From 578764d85ecf954b0bebec3122e88b95df31b24f Mon Sep 17 00:00:00 2001 From: Claude Date: Thu, 24 Sep 2026 20:10:21 +0000 Subject: [PATCH 01/35] fix(worktree): self-heal wedged task worktrees and stop clobbering remote work Multi-agent runs kept leaving task worktrees in states nothing recovered from automatically. create_worktree/rebase/commit/push now heal them: - Detached HEAD / other branch: a clean checkout is switched back onto its task branch in place (fast-forwarding over detached commits, or pinning diverged ones under refs/agentflare/rescue/) instead of `worktree add` failing on the occupied path every redispatch. - Interrupted git: abandoned index.lock (>10 min, or ours after a timeout kill) is removed and a half-finished rebase aborted; the abort result is checked instead of discarded. - Half-created checkout (worktree add killed mid-populate, "initializing" lock left) is recreated rather than reused and committed as mass deletions. - Broken .git pointer: repaired, else snapshotted and cleared; commit and cleanup refuse to run in it (git would act on the main repo). - push uses --force-if-includes and, on rejection, integrates origin/ and retries once, so human/update-branch commits on the PR branch are kept instead of dropped or rejected forever. - worktree add retries recompute -b after a partial success, match real ref/index lock errors, and run under a timeout. - branch_diverged checks against origin/ as well as the (never pulled) local target. - gc_orphans drops only the removed path's registration instead of a repo-wide `worktree prune`; relative gitdir pointers are resolved; the branch-scoped cleaner honors locked registrations. - cleanup pins detached-only commits before removal; squash_since refuses a base that is no longer an ancestor of HEAD. --- crates/flare-git-core/src/worktree.rs | 565 ++++++++++++++++---- crates/flare-git-core/src/worktree_tests.rs | 322 +++++++++++ 2 files changed, 796 insertions(+), 91 deletions(-) diff --git a/crates/flare-git-core/src/worktree.rs b/crates/flare-git-core/src/worktree.rs index 5b6649ed5..0e6f13495 100644 --- a/crates/flare-git-core/src/worktree.rs +++ b/crates/flare-git-core/src/worktree.rs @@ -45,9 +45,242 @@ pub fn is_retryable_worktree_race(err: &str) -> bool { || e.contains("could not lock") || e.contains("unable to lock") || e.contains("already locked") + || e.contains("cannot lock ref") + || (e.contains("unable to create") && e.contains(".lock")) || (e.contains("worktree add") && e.contains("already exists")) } +/// `.worktrees/task/` under `repo_root` -- the one place every +/// per-item worktree lives. +#[must_use] +pub fn item_worktree_path(repo_root: &Path, sequence_id: i64) -> PathBuf { + repo_root + .join(".worktrees") + .join("task") + .join(sequence_id.to_string()) +} + +/// [`run_output_timeout`] against git, shaped like `shell::run_in`: +/// `Ok(stdout)` trimmed on success, `Err(stderr)` (or the spawn/timeout +/// message) otherwise. +fn run_git_timeout(cwd: &Path, args: &[&str], timeout_secs: u64) -> Result { + let out = run_output_timeout(crate::shell::git_binary(), args, cwd, timeout_secs)?; + if out.status.success() { + Ok(String::from_utf8_lossy(&out.stdout).trim().to_string()) + } else { + Err(String::from_utf8_lossy(&out.stderr).trim().to_string()) + } +} + +/// Deadline for one `git worktree add`, checkout hooks included. +const WORKTREE_ADD_TIMEOUT_SECS: u64 = 600; + +/// How old a leftover `index.lock` must be before it's presumed abandoned by +/// a killed git process rather than held by a live one.

lock claimed worktrees - Every git spawn now gets LC_MESSAGES=C/LANGUAGE= (LC_ALL removed): lock-race retries, push-rejection recovery and the force-if-includes fallback all classify git's English stderr, and silently did nothing on a non-English workstation. - GIT_TERMINAL_PROMPT=0 / GCM_INTERACTIVE=never: a credential prompt fails fast as an auth error instead of hanging until a timeout, or forever for calls without one. - GIT_OPTIONAL_LOCKS=0: the daemon's read-only status polling no longer takes index.lock in a worktree an agent is committing in. - Claimed worktrees are `git worktree lock`ed with an agentflare reason so an outside `worktree prune`/gc can't drop their registration; our own cleaners unlock/remove only registrations carrying that reason. - A child item stops targeting its parent's branch once the parent is completed or cancelled, instead of stacking on an already-landed (squash-merged) branch and conflicting on every rebase. - A worktree whose changes can't be auto-committed because its checkout is broken now fails `done` loudly (item #92) instead of reading as "nothing to commit". --- crates/flare-git-core/src/shell.rs | 19 +++++++ crates/flare-git-core/src/worktree.rs | 47 +++++++++++++++- crates/flare-git-core/src/worktree_tests.rs | 61 ++++++++++++++++++++- src/mcp_server/tests/action_tests.rs | 16 ++++-- 4 files changed, 133 insertions(+), 10 deletions(-) diff --git a/crates/flare-git-core/src/shell.rs b/crates/flare-git-core/src/shell.rs index 8be697ad2..47868bdb6 100644 --- a/crates/flare-git-core/src/shell.rs +++ b/crates/flare-git-core/src/shell.rs @@ -146,10 +146,29 @@ pub(crate) fn git_binary() -> PathBuf { /// spawn can still hit `E2BIG` even though `git_binary()` already computed a /// clean PATH, because that clean PATH was only ever used to *locate* the /// binary, never applied to the child's actual env. +/// +/// Also pins the environment every daemon-side git call needs to be safe +/// unattended: +/// - `LC_MESSAGES=C`/`LANGUAGE=` (and no `LC_ALL`, which would override +/// them): callers classify failures by matching git's English stderr +/// (lock races, push rejections);

stop double dispatch - mark_completed / mark_in_review / promote / redispatch / release use IMMEDIATE transactions: DEFERRED read-then-write failed instantly with SQLITE_BUSY_SNAPSHOT under concurrent writers, erroring `done` after its PR was already open. - mark_in_review / mark_completed only move items in the started or in_review group, so a late finalize can't revive a cancelled, completed or redispatched item. - promote_in_review_to_completed_if_pr compare-and-sets on the PR number that was verified merged. - acquire_if_stale_only / ClaimLedger::acquire_existing: a steal never re-creates a released claim row, so a reassigned job can't take the item back and publish. - Supervisor dispatch decision waits on ANY live claim (the item's own assignee session included -- it was invisible, causing dispatch -> Held -> failure-cap -> needs-manual-dispatch) using the real 4h item claim TTL instead of the 30 min repo-claim TTL; same TTL fix in handoff. New tier waits while blocking dependencies are incomplete. - Fallback claim owner is :-, unique per process, instead of : which collided across sandboxes/machines. - `git worktree audit/doctor`: claimed_sequence_ids and item_state_groups read backend.db (they read the wrong database and always came back empty), are scoped to the repo's own project, and the claim guard fails closed. --- crates/agentflare-backend/src/claim.rs | 51 +++++ crates/agentflare-backend/src/item/claim.rs | 85 +++++++- crates/agentflare-backend/src/item/tests.rs | 2 + .../src/item/tests_finalize.rs | 192 ++++++++++++++++++ crates/agentflare-db-kit/src/claim.rs | 109 ++++++++++ src/claims.rs | 34 +++- src/cli/git.rs | 162 ++++++++++----- src/mcp_server/handoff.rs | 10 +- src/quota/decide.rs | 161 +++++++++++++-- 9 files changed, 733 insertions(+), 73 deletions(-) create mode 100644 crates/agentflare-backend/src/item/tests_finalize.rs diff --git a/crates/agentflare-backend/src/claim.rs b/crates/agentflare-backend/src/claim.rs index 324fa0f48..77cd4391d 100644 --- a/crates/agentflare-backend/src/claim.rs +++ b/crates/agentflare-backend/src/claim.rs @@ -19,6 +19,23 @@ pub fn acquire( LEDGER.acquire(conn, &[item_id], owner, now, ttl_secs) } +/// Steal-only acquire: takes over an existing done, stale, or already-ours +/// lease on `item_id` exactly like `acquire`, but returns `Ok(None)` +/// instead of creating one when no row exists.

New resume_run / is_driving / is_leased_elsewhere / recover_with and patch_run_data (a context patch that survives an in-flight step's write-back). - agentflare-jobs: a watchdog timeout now flags the attempt cancelled so its agent children and run actually stop before the retry, instead of abandoning a live thread that keeps heartbeating the claim. - Launched agents record pid + start-time under agent-pids/; orphan reconcile kills that recorded group (not only `pgrep -f`, which never matched on macOS/Windows where the path isn't in argv) and, on Linux, processes whose cwd is inside the worktree -- except ones with a controlling terminal, i.e. a human's shell. - orphan reconcile: the terminal-failure label swap runs in one BEGIN IMMEDIATE transaction (retried), so an item can no longer end up with neither `dispatched` nor `ready-for-work` and vanish from dispatch; restore_ready_for_work uses IMMEDIATE too. - daemon: the lock file is never deleted (deleting it let two processes both "hold" it) and a lifetime flock is the liveness test. --- crates/agentflare-jobs/src/worker.rs | 114 +++++- crates/flare-workflow/src/engine.rs | 403 +++++++++++++++++++-- crates/flare-workflow/src/loops.rs | 4 + crates/flare-workflow/src/types.rs | 30 ++ crates/flare-workflow/tests/lease_test.rs | 423 ++++++++++++++++++++++ src/agent_launch.rs | 133 +++++++ src/agent_launch_tests.rs | 58 +++ src/daemon.rs | 100 ++++- src/dashboard/orphan_reconcile.rs | 410 +++++++++++++++++---- 9 files changed, 1560 insertions(+), 115 deletions(-) create mode 100644 crates/flare-workflow/tests/lease_test.rs diff --git a/crates/agentflare-jobs/src/worker.rs b/crates/agentflare-jobs/src/worker.rs index c97545013..a1cc16448 100644 --- a/crates/agentflare-jobs/src/worker.rs +++ b/crates/agentflare-jobs/src/worker.rs @@ -161,8 +161,11 @@ fn worker_loop( /// in-process job has no OS-level SIGKILL backstop the way a subprocess does /// (a stuck claim/worktree/done step can't be force-killed), so without this /// a hang there would wedge one of the pool's worker threads forever.

a closed own PR is never reused. - push_and_open_pr returns PrOutcome; "no PR possible by configuration" (non-GitHub/no origin/no credentials) completes the item with metadata.no_pr instead of failing `done` forever; transient failures still error so finalize retries. - find_existing queries head=: (one request, no unbounded pagination), prefers metadata.pr.number, and a lookup error never falls through to creating a duplicate PR. - Metadata writes (PR identity, run id, item_update) re-read, merge and write in one IMMEDIATE transaction instead of clobbering concurrent writes from a snapshot. - Finalize treats item_done's "unchanged" as a failure (re-armed by the terminal-failure hook) rather than reporting success. - item_claim rolls back the claim and prior state when the worktree can't be created (non-retryable); item_done refuses completed or cancelled items; discovery resumes its own earlier PR claim. - Supervisor: one project's DB error or missing folder no longer aborts the discovery tick for every project; per-project cap on active work jobs when several projects have ready items; job_in_flight uses an EXISTS query instead of the 100 newest jobs; a failed boot recover() retries every 60s instead of leaving dispatch off until restart. - Restart wiring: an attached run adopts the current owner (finalize was refused after a restart and all work redone), stale runs are taken over instead of waited on forever, a lost claim or cancelled job stops the run, and boot recovery skips runs whose item is already finished. - done/release steal only an existing stale claim: a job that lost its item to a reassignment can't re-mint the lease and publish. promote compare-and-sets on the PR number verified merged. --- crates/agentflare-backend/src/item/claim.rs | 31 ++ crates/agentflare-jobs/src/queue.rs | 29 ++ src/cli/work_dispatch_fixture_tests.rs | 32 +- src/dashboard/server.rs | 125 ++++-- src/github/graphql.rs | 7 +- src/github/pulls.rs | 22 +- src/mcp_server.rs | 188 ++++++++- src/mcp_server/item.rs | 149 ++++++- src/mcp_server/item_status.rs | 1 + src/mcp_server/project_resolution.rs | 56 ++- src/mcp_server/tests/item_pr_failure_tests.rs | 372 +++++++++++++----- src/supervisor.rs | 211 +++++++++- .../tests/multi_project_sweep_tests.rs | 210 ++++++++++ src/supervisor_project_scope_tests.rs | 6 +- src/supervisor_tests.rs | 16 +- src/work_item_pipeline.rs | 300 +++++++++++--- src/work_item_pipeline/tests.rs | 146 ++++--- src/worktree/discovery.rs | 50 ++- src/worktree/mod.rs | 342 +++++++++++----- src/worktree/mod_tests.rs | 111 +++++- 20 files changed, 1992 insertions(+), 412 deletions(-) create mode 100644 src/supervisor/tests/multi_project_sweep_tests.rs diff --git a/crates/agentflare-backend/src/item/claim.rs b/crates/agentflare-backend/src/item/claim.rs index ae1a52b64..f663116f8 100644 --- a/crates/agentflare-backend/src/item/claim.rs +++ b/crates/agentflare-backend/src/item/claim.rs @@ -460,3 +460,34 @@ pub fn redispatch( assignee_agent: agent, }) } + +/// The abandoned-claim steal `done`/`release` run when the caller doesn't +/// hold the lease (item #83): a live claim by someone else comes back as +/// `Held`;

Claims of crashed interactive sessions or killed `agentflare work` processes are freed in about a minute instead of after the 4h TTL. release/done take over a dead owner's claim immediately. Headless runs register their session. Job controls (src/job_controls.rs, flare-workflow, agentflare-jobs): - cancel really stops: cancels the item's run and queued/running jobs, kills the agent, releases the claim, and is never retried/re-queued. - pause/resume: the engine stops at the next step boundary (the stopped step is not journaled as a failure) and resumes the same run in the same worktree; a `paused` label holds the item meanwhile. - `agentflare job cancel|pause|resume`, `agentflare item cancel|pause|resume|redispatch [--agent]`, MCP item actions, dashboard POST /api/jobs/{id}/cancel and /api/items/{id}/{action}, chat /cancel /pause /resume /redispatch. - handoff of a claimed item to another agent releases the old claim and cancels its jobs. Agent failover (src/auth_runner_classify.rs, src/quota/failover.rs, src/cli/work_failover.rs, agent-registry): agent failures are classified (short rate limit, long rate limit, credit exhausted, usage window with parsed reset time, auth expired). Credit/window exhaustion and long rate limits cool the agent down until its reset and move the item to the next available agent immediately, without charging the item's dispatch failure ceiling; with no alternative the retry is scheduled at the reset time. Configurable via AGENTFLARE_FAILOVER, [failover] in config.toml, and per-item allowed_agents / failover:false. A hung agent whose output only repeats while its worktree doesn't change is killed after 45 min (AGENTFLARE_STALL_WINDOW_SECS); repeated mid-run exhaustion errors kill it early into failover. Realtime inter-agent messaging (src/messages.rs, src/hook_messages.rs): MCP tool `message` (send/list/inbox/read/whoami), CLI `agentflare message send|list|inbox|read|whoami|watch`, dashboard /api/sessions, /api/messages and an SSE stream, chat /msg.

back under LOC gate Behavior-preserving: - AgentflareMcp::post_item_comment replaces 11 copies of the best-effort `comment_impl(CommentRequest{action:"create",..})` call. - metadata_object() replaces the copied coerce-metadata-to-object chain (merge_item_metadata, handoff merges, persist_comment_cursor). - item.rs: require_id / internal_err replace 13 id preambles and 12 internal-error mappings; the progress sender is fetched once instead of calling create_worktree / push_and_open_pr through two branches. - claims::ttl_secs delegates to the backend's identical default; wrapper tests that duplicated db-kit's ClaimLedger tests are dropped. - groom/standup/health handlers move verbatim to item_reports.rs and the finalize step to work_item_pipeline/finalize.rs: item.rs 3113 -> 2633 and work_item_pipeline.rs 1749 -> 1488 lines, both back under scripts/loc-gate.sh limits. --- crates/agentflare-backend/src/claim.rs | 5 +- crates/agentflare-db-kit/src/claim.rs | 3 +- src/claims.rs | 82 +--- src/cli/work.rs | 7 +- src/cli/work_failover.rs | 14 +- src/mcp_server.rs | 39 +- src/mcp_server/handoff.rs | 38 +- src/mcp_server/item.rs | 616 +++---------------------- src/mcp_server/item_reports.rs | 425 +++++++++++++++++ src/work_item_pipeline.rs | 275 +---------- src/work_item_pipeline/finalize.rs | 237 ++++++++++ 11 files changed, 789 insertions(+), 952 deletions(-) create mode 100644 src/mcp_server/item_reports.rs create mode 100644 src/work_item_pipeline/finalize.rs diff --git a/crates/agentflare-backend/src/claim.rs b/crates/agentflare-backend/src/claim.rs index 77cd4391d..93848162a 100644 --- a/crates/agentflare-backend/src/claim.rs +++ b/crates/agentflare-backend/src/claim.rs @@ -57,9 +57,8 @@ pub fn is_owner(conn: &Connection, item_id: &str, owner: &str) -> rusqlite::Resu LEDGER.is_owner(conn, &[item_id], owner) } -/// Default claim TTL, mirrored from the main binary's `claims::ttl_secs()` -/// (this lower-level crate can't depend on it) — override via -/// AGENTFLARE_CLAIM_TTL_SECS so the two stay in sync. +/// Default claim TTL (override via AGENTFLARE_CLAIM_TTL_SECS) -- the single +/// source of truth;

A clean, mergeable PR with no CI at all is Passing instead of Pending forever. - New PrCiStatus::AwaitingReview (blocked + REVIEW_REQUIRED / CHANGES_REQUESTED with green checks) takes the approval-gate path, so the human is actually pinged, with no merge attempt. - Secondary rate limits (403/429 with retry-after or "secondary rate limit"/"abuse") map to RateLimited instead of a token-scope error; a shared per-host backoff deadline short-circuits calls until it passes; mutating requests are serialized >= 1s apart; GraphQL RATE_LIMITED errors map to RateLimited. - The gh/vault token is resolved once per process and refreshed on 401. - After a merged item is promoted, its remote head branch is deleted unless the repo auto-deletes, it is the default/protected branch, or the head lives in a fork. - PRs for items bridged from a GitHub issue include "Closes #N" (or owner/repo#N across repos). --- src/github/actions.rs | 58 +++++ src/github/auth.rs | 74 ++++++- src/github/client.rs | 391 +++++++++++++++++++++++++++++++--- src/github/graphql.rs | 141 ++++++++++-- src/github/models.rs | 39 ++++ src/github/pulls.rs | 87 +++++++- src/github/repos.rs | 210 +++++++++++++++++- src/mcp_server/item_status.rs | 9 +- src/supervisor.rs | 352 ++++++++++++++++++++---------- src/supervisor_tests.rs | 107 +++++++++- src/worktree/mod.rs | 214 ++++++++++++++++--- src/worktree/mod_tests.rs | 268 ++++++++++++++++++++++- 12 files changed, 1749 insertions(+), 201 deletions(-) diff --git a/src/github/actions.rs b/src/github/actions.rs index f927667b0..c643a3767 100644 --- a/src/github/actions.rs +++ b/src/github/actions.rs @@ -87,6 +87,41 @@ pub fn list_check_runs( serde_json::from_value(arr).map_err(|e| GitHubError::Parse(e.to_string())) } +/// Legacy commit statuses (the Statuses API -- third-party CI, CLA bots, +/// deploy previews) for a commit SHA, folded into the check-run shape via +/// `CheckRun::from_status`.

Messaging / sessions / failover: - `message watch` and the SSE stream requeue a taken message whose print/send failed instead of losing the rest of the batch. - Envelope-tag escaping is case- and whitespace-insensitive. - The MCP server's provisional session row is deleted, not ended, so its live claims aren't judged dead. - Session host identity uses the kernel hostname (same for daemons and shells), then the machine id, before "localhost". - A typo'd failover allow-list disables failover instead of widening to any agent; the agent-wide "no alternative" cache is only armed for unrestricted items; short rate-limit retries post the neutral agent-unavailable marker; a stale cancelled run id no longer makes a fresh dispatch's setup error read as a cancel; handoff compares canonical agent names. --- .claude/settings.json | 2 +- crates/agent-registry/src/failover.rs | 23 +- crates/agentflare-jobs/src/queue.rs | 53 ++- crates/agentflare-jobs/src/worker.rs | 98 +++++- crates/flare-git-core/src/worktree_heal.rs | 23 +- .../flare-git-core/src/worktree_heal_tests.rs | 61 ++++ crates/flare-git-core/src/worktree_orphans.rs | 6 + crates/flare-git-core/src/worktree_tests.rs | 25 ++ crates/flare-workflow/src/engine.rs | 86 ++++- crates/flare-workflow/src/engine_control.rs | 36 +- crates/flare-workflow/src/engine_lease.rs | 60 +++- crates/flare-workflow/src/loops.rs | 9 +- .../tests/driver_exclusivity_test.rs | 316 ++++++++++++++++++ crates/flare-workflow/tests/engine_test.rs | 5 +- src/cli/message.rs | 56 +++- src/cli/work.rs | 10 +- src/cli/work_failover.rs | 68 ++-- src/cli/work_failover_tests.rs | 27 ++ src/dashboard/messages.rs | 24 +- src/github/client.rs | 78 ++++- src/github/graphql.rs | 47 ++- src/github/mod.rs | 42 +++ src/github/pulls.rs | 2 +- src/github/repos.rs | 40 ++- src/job_controls.rs | 8 +- src/mcp_server/handoff.rs | 48 ++- src/messages.rs | 37 +- src/messages/identity.rs | 17 +- src/quota/failover.rs | 26 +- src/sessions.rs | 92 ++++- src/supervisor.rs | 15 +- src/supervisor/merge.rs | 14 +- src/supervisor/telegram.rs | 4 +- src/supervisor/tests/auto_merge_tests.rs | 5 +- 34 files changed, 1292 insertions(+), 171 deletions(-) create mode 100644 crates/flare-workflow/tests/driver_exclusivity_test.rs diff --git a/.claude/settings.json b/.claude/settings.json index 3d10a7757..7c71b9c46 100644 --- a/.claude/settings.json +++ b/.claude/settings.json @@ -5,7 +5,7 @@ "hooks": [ { "type": "command", - "command": "$CLAUDE_PROJECT_DIR/.claude/hooks/session-start.sh", + "command": "\"$CLAUDE_PROJECT_DIR\"/.claude/hooks/session-start.sh", "timeout": 1800 } ] diff --git a/crates/agent-registry/src/failover.rs b/crates/agent-registry/src/failover.rs index a597dbe3c..bd7edbb56 100644 --- a/crates/agent-registry/src/failover.rs +++ b/crates/agent-registry/src/failover.rs @@ -45,15 +45,20 @@ struct RawFile { /// Parses the `[failover]` table out of a config.toml-shaped document, /// ignoring every other table.

Findings are ranked P0-P2 with file:line evidence, a per-feature status matrix, the current per-agent capability table, a list of Claude-Code- style features worth universalising with the agentflare mechanism each maps onto, and a roadmap. Two bugs surfaced by the audit are recorded for follow-up rather than fixed here: `agentflare work` passes both `--output-format json` and `--output-format stream-json`, which makes the whole-stdout JSON parse fail and silently drops session_id and cost (so SDD-loop `--resume` never fires in real dispatch); and `agentflare run --mode` forwards `--mode`, which is not a Claude Code flag (`--permission-mode` is).

The `ctx_*` MCP tools were not loaded in the auditing session, so +the lean-ctx CLI and shell hook were used instead. Every claim about agentflare +cites `path:line` on this branch. + +--- + +## 1. Verdict + +agentflare touches Claude Code at three layers, and they are very unequal. + +**Layer A, Claude Code as an instrumented host** (`agentflare init --agent +claude-code`): deep. agentflare wires 9 of Claude Code's 33 hook events, a +status line, `permissions.allow`, `env.BASH_ENV`, `~/.claude/rules`, an MCP +server with 31 tools, 2 resources and 12 slash-command prompts, a skills +registry with intent-based injection, coaching rules, a live-session registry +with inter-agent messaging, and a completion gate. This is a serious use of the +hook system. It uses only two of the hook system's output verbs (`deny` and +`additionalContext`), only the `command` hook type, and only user-scope +settings. + +**Layer B, Claude Code as a headless worker** (`agentflare work`, `agentflare +run --print`, `flare-workflow` steps, Apps, Telegram chat, `optimize output`): +shallow. agentflare launches `claude -p` with seven flags and reads three +fields off the reply. It does not use system-prompt injection, structured +output, tool allow/deny lists, permission modes, per-run MCP config, per-run +settings, subagent invocation, session naming or forking, effort or thinking +controls, native sandbox settings, or the Agent SDK. One launch path also has a +flag collision that defeats the session-resume and cost features it does use +(§2.3). Everything Claude Code offers to make a worker *role-shaped* is left on +the table, and role shaping is done by prose in the user prompt instead. + +**Layer C, the agent-agnostic layer**: the registry knows 20 agents, but the +capability table is thin: 6 have a headless mode, 2 have JSON output and +resume, 1 has turn/budget caps. Hooks are emulated for Cursor (3 events), +Codex (1 event plus a 2-event plugin), Cline (a 4-callback JS plugin) and +OpenCode (a branch-guard plugin), versus 9 events on Claude Code. Most of the +value agentflare generates for Claude users through hooks reaches other agents +only when those agents call agentflare's MCP tools. + +### Top findings + +| # | Finding | Severity | +|---|---------|----------| +| 1 | **Flag collision breaks resume and cost in `agentflare work`.** `run_headless_impl` adds `--output-format json` when `request_json` is set (`src/agent_launch.rs:847`), then `build_extra_args` appends `--output-format stream-json --verbose` (`src/cli/work.rs:253-258`). With the last flag winning, stdout is multi-line stream-json, `parse_json_reply` (`:676-698`) fails to parse it as one object and returns `session_id: None`, `cost_usd: None`. The SDD loop's `--resume` between fix rounds (`src/work_item_pipeline.rs:254-268`) and the per-job cost therefore never fire in real dispatch; the unit tests pass because they feed the parser a single object. | P0 bug | +| 2 | **Headless workers are launched bare.** No `--append-system-prompt(-file)`, `--allowedTools`/`--disallowedTools`, `--permission-mode`, `--mcp-config`/`--strict-mcp-config`, `--settings`/`--setting-sources`, `--agent`/`--agents`, `--add-dir`, `--json-schema`, `--effort`, `--name`, `--fork-session`. Role prompts, tool policy and MCP wiring for workers are done by text in the user prompt or by mutating the user's global `~/.claude` state, and verdicts are regex-matched on marker strings. | P0 | +| 3 | **`--dangerously-skip-permissions` is the only permission posture.** `--permission-mode` (`plan`, `acceptEdits`, `dontAsk`, `auto`), `permissions.deny`, `permissions.disableBypassPermissionsMode`, `autoMode` rules and `sandbox.*` are unused; agentflare relies solely on its own bwrap sandbox and PreToolUse branch guard. | P0 | +| 4 | **Personas are subagent files that are never invoked as subagents.** Apps project `personas/*.md` into `.claude/agents/` (`crates/agentflare-apps/src/project.rs:4-26`), but `apps/auto-company/workflow.json` prompts say "Read `.claude/agents/<persona>.md` and answer in that voice". `--agent <name>`, `--agents`, `@agent-name`, `SubagentStart`/`SubagentStop` (beyond `optimize code`), and agent frontmatter (`tools`, `model`, `permissionMode`, `maxTurns`, `skills`, `memory`, `hooks`, `mcpServers`, `isolation: worktree`) are unused. | P0 | +| 5 | **`PreCompact` is wired but a documented no-op** (`src/hook.rs:593-608`) while README and AGENTS.md still advertise `optimize context` as PreCompact compaction. `PostCompact` exists and is the event that can re-inject survival context. `SessionStart` ignores `source` (`startup|resume|clear|compact`), so the full briefing is re-injected after every compaction. | P1 | +| 6 | **Hook system used at 2 of 5 types and 2 of 9 output verbs.** Unused: `mcp_tool` hooks (call agentflare's own MCP server per event instead of spawning a process), `http` hooks (post to the daemon), `prompt`/`agent` hooks (the judge role), `permissionDecision: allow|ask|defer`, `updatedInput`, `PermissionRequest`, `PermissionDenied`+`retry`, `StopFailure` (API-error failover trigger), `Notification`, `TaskCreated`/`TaskCompleted`, `PreModelSwitch`/`PostModelSwitch`, `WorktreeCreate`/`WorktreeRemove`, `Setup`, the `if` field. | P1 | +| 7 | **Interactive `agentflare run claude-code --mode X` passes `--mode`** (`src/agent_launch.rs:101-103`), which is not a Claude Code flag; the real one is `--permission-mode`. | P1 bug | +| 8 | **Config-dir and uninstall hygiene.** `~/.claude` is hard-coded (`src/paths.rs:36-60`; only `crates/flare-code/src/config.rs:58-80` honours `CLAUDE_CONFIG_DIR`); auth-profile isolation overrides `HOME` (`src/auth.rs:952`), relocating hooks, memory and plugins too; `wire_optimize_claude_code` overwrites any existing `statusLine` (`src/init.rs:665`); `uninstall` leaves `PreCompact`, `PostToolUse`, `PostToolUseFailure`, `SubagentStart`, `statusLine`, `permissions.allow`, `env.BASH_ENV` and rule files behind (`src/uninstall.rs:55-110`). | P1 | +| 9 | **Distribution and interop.** No Claude plugin (`.claude-plugin/plugin.json`), only Codex and Cline plugins; no `claude mcp serve` adapter; no `--channels` push messaging; no Agent SDK; no GitHub Action or Routines recipe; `~/.claude/.credentials.json` is read directly for usage polling (`src/claude_usage.rs:23-64`). | P2 | + +--- + +## 2.

Also fixes the `--mode` bug. | +| `--permission-prompts none`, `--permission-prompt-tool` | Unused | The supported way to run unattended without bypassing permissions: route prompts to a tool (agentflare's MCP server) that applies the branch guard and completion gate. | +| `--dangerously-skip-permissions` | Used | Keep for sandboxed jobs; pair with `--disallowedTools` and `permissions.deny`. | +| `--max-turns`, `--max-budget-usd` | Used | Handle `subtype` explicitly. | +| `--model`, `--fallback-model` | Partial | `--fallback-model` gives in-process failover before agentflare's cross-agent failover. | +| `--effort` | Unused | `TaskModelTier` picks a model per task; effort is the cheaper second axis. | +| `--resume <id|name|path>`, `--continue` | Used / Unused | Resume by name or transcript path also works. | +| `-n/--name`, `--fork-session`, `--session-id`, `--from-pr` | Unused | Name sessions after `<item>:<role>:<round>` so they are addressable from the item record; fork one implementer session into parallel reviewers; `--from-pr` links sessions to PRs for `check_merge`. | +| `--mcp-config`, `--strict-mcp-config` | Unused | Per-job MCP wiring (flare, lean-ctx, GitHub) without mutating `~/.claude.json`. Apps already write a project `.mcp.json`; jobs should too. | +| `--settings`, `--setting-sources` | Unused | Job-scoped settings (hooks, permissions, `env`, `model`, `statusLine` off, `attribution.commit=false`). | +| `--add-dir` | Unused | Worktree jobs that need the main checkout or a sibling repo read-only. | +| `--agent`, `--agents` | Unused | See §3.6. | +| `--bare` | Unused | For deterministic CI-like jobs: skips hooks, skills, subagents, MCP and CLAUDE.md the user did not opt into. Note it also skips agentflare's own hooks, so pair with `--mcp-config` and `--settings`. | +| `--no-session-persistence`, `CLAUDE_CODE_SKIP_PROMPT_HISTORY` | Unused | For throwaway judge turns; keep persistence where cost roll-up depends on transcripts. | +| `--plugin-dir`, `--plugin-url` | Unused | Load agentflare as a plugin per job without installing it. | +| `--worktree`, `--cloud`, `--remote-control`, `--channels`, `--chrome`, `--tmux`, `--teammate-mode` | Unused | `--channels` matters: an MCP server with the `claude/channel` capability can push messages into a live session, replacing the `Stop`-block delivery hack. | +| `--init-only` / `Setup` hook | Unused | The supported way to run one-time setup (agentflare's install steps) inside Claude's own lifecycle. | +| `claude mcp add|remove|list|get|serve`, `claude plugin …`, `claude doctor`, `claude setup-token`, `claude project purge` | Partial | `mcp add/remove` used. `setup-token` is the supported way to mint long-lived tokens instead of reading `.credentials.json`. | + +### 3.2 Settings + +| Key | Status | Notes | +|---|---|---| +| `hooks` | Used | User scope only.

Also the right place for `AGENTFLARE_*` and proxy variables for workers. | +| `permissions.deny` / `ask` / `additionalDirectories` / `blockReadsOutsideWorkingDirectories` / `disableBypassPermissionsMode` | Unused | Branch guard and destructive-command classification can be expressed as `deny` rules as a first, hook-free layer; `disableBypassPermissionsMode` for interactive installs. | +| `autoMode`, `autoMode.classifyAllShell` | Unused | Claude's classifier-based auto mode overlaps with `hook_redirect::classify`. | +| `model`, `fallbackModel`, `effortLevel`, `maxEffortLevel`, `modelSettings`, `alwaysThinkingEnabled` | Unused | | +| `outputStyle` | Unused | `optimize output` (caveman) is prompt injection; an output style is the native mechanism and survives compaction. | +| `enabledPlugins`, `extraKnownMarketplaces`, `pluginConfigs` | Unused | See §3.8. | +| `allowedMcpServers`, `enabledMcpjsonServers`, `enableAllProjectMcpServers` | Partial | Apps set `enableAllProjectMcpServers`; jobs should approve only the servers they ship. | +| `sandbox.*` (filesystem, network, credentials) | Unused | Native sandbox duplicates part of `flare-sandbox`; at minimum detect `sandbox.enabled` and avoid double-wrapping bwrap in bwrap. | +| `attribution.commit`, `attribution.pr`, `includeGitInstructions` | Unused | AGENTS.md forbids co-author trailers; `attribution.commit: false` enforces it. | +| `cleanupPeriodDays` | Unused | Cost roll-ups depend on transcripts Claude deletes after this period. | +| `autoMemoryEnabled`, `autoMemoryDirectory` | Unused | See §3.4. | +| `autoCompactEnabled`, `autoCompactWindow`, `bashOutputMaxChars`, `skillListingBudgetFraction` | Unused | Context-budget knobs that `optimize` should tune for hosts it instruments. | +| `crossSessionInbound`, `isolatePeerMachines` | Unused | Native cross-session messaging; decide how it coexists with `message`. | +| `processWrapper` | Unused | Where a corporate launcher (or agentflare's sandbox) is meant to be declared. | +| `disableSideloadFlags`, `strictPluginOnlyCustomization`, `allowManagedHooksOnly` | Unused | In managed environments these reject `--agents`/`--mcp-config`/`--plugin-dir` and user hooks. Any P0 plan that relies on flags needs the plugin path as fallback. | +| `CLAUDE_CONFIG_DIR` | Partial | Honoured in `flare-code` only; `src/paths.rs` hard-codes `~/.claude`. | + +### 3.3 Hooks + +Claude Code has 33 events, 5 hook types (`command`, `http`, `prompt`, +`agent`, `mcp_tool`), an `if` filter, and 9 output verbs. agentflare uses 9 +events, 1 type, 2 verbs (`deny`, `additionalContext`) plus `decision: block` +on `Stop` and `systemMessage` on `SessionStart`. + +| Event / capability | Status | Notes | +|---|---|---| +| `SessionStart` | Used | Ignores `source`; on `compact` re-inject only survival context, on `resume` skip the consent banner. Use `CLAUDE_ENV_FILE` to export `AGENTFLARE_*`. | +| `UserPromptSubmit` | Used | `decision: block` unused (e.g. refuse `agentflare work` under an AI agent). | +| `PreToolUse` | Used | `allow` (pre-approve gateway tools, cut prompts), `ask`, `defer`, `updatedInput` (rewrite a call, as lean-ctx does) unused. `if` field could replace part of `classify`. | +| `PostToolUse`, `PostToolUseFailure`, `Stop`, `SessionEnd` | Used | `SessionEnd.reason` distinguishes crash from exit for the registry. `CLAUDE_CODE_STOP_HOOK_BLOCK_CAP` bounds the `Stop` block loop. | +| `PreCompact` | Wired, no-op | Remove or use to checkpoint `runtime.json` evidence into agentflare memory. | +| `PostCompact` | Unused | The event that can re-inject agentflare's survival context after compaction. | +| `SubagentStart` | Partial | `optimize code` only. | +| `SubagentStop` | Unused | Record a reviewer subagent's verdict for the completion gate. | +| `PermissionRequest`, `PermissionDenied` (+`retry`) | Unused | Answer permission prompts programmatically instead of skipping permissions. | +| `StopFailure` | Unused | Fires on API errors (quota, 5xx): the natural trigger for `quota::failover` instead of scraping stdout. | +| `Notification` | Unused | Route "waiting for input"/"idle" to `channel_send` and the dashboard. | +| `TaskCreated`, `TaskCompleted` | Unused | Sync Claude's native tasks with agentflare items (today `TodoWrite` is denied and redirected). | +| `PreModelSwitch`, `PostModelSwitch` | Unused | Enforce `[router]` policy and quota-aware model choice natively. | +| `WorktreeCreate`, `WorktreeRemove` | Unused | Reconcile Claude-created worktrees with agentflare claims. | +| `Setup`, `InstructionsLoaded`, `ConfigChange`, `CwdChanged`, `FileChanged`, `PostToolBatch`, `UserPromptExpansion`, `MessageDisplay`, `Elicitation*`, `TeammateIdle` | Unused | `Setup` for install; `ConfigChange` to detect a user editing hooks agentflare wrote. | +| Hook type `mcp_tool` | Unused | Call `mcp__flare__*` directly per event: no process spawn, shared state, and the hook logic already lives in the MCP server process. | +| Hook type `http` | Unused | Post to the daemon; needs `allowedHttpHookUrls`. | +| Hook types `prompt`, `agent` | Unused | Tried and retired for `PostToolUseFailure`; `agent` is the right tool for the judge role. | +| `async: true` | Unused | Vent consolidation and messaging sync in `SessionStart` block startup. | +| Input fields `permission_mode`, `effort`, `prompt_id`, `tool_use_id`, `scratchpad_dir` | Unused | `permission_mode` lets the branch guard relax under `plan`. | + +### 3.4 Instructions and memory + +| Feature | Status | Notes | +|---|---|---| +| `CLAUDE.md` hierarchy, `@imports`, `CLAUDE.local.md`, managed `claudeMd` | Partial | agentflare writes `~/.claude/rules/*.md` and reads `AGENTS.md`; never writes or verifies `CLAUDE.md`. Claude Code v2.1.277+ reads `AGENTS.md` directly, so agentflare's AGENTS.md is already loaded natively. | +| `.claude/rules/*.md` with `paths:` frontmatter | Unused | Path-scoped rules (e.g. lean-ctx rule only for source files, git rule only near `.git`). | +| Auto memory (`MEMORY.md`, topic files, `type:` frontmatter) | Unused | Bridge both ways: import Claude's auto memory into `memory(remember)`; export agentflare facts into `MEMORY.md` (200 lines / 25KB cap). | +| `/import` | Unused | Claude's own import of Cursor/Copilot config is the mirror image of agentflare's rule-file fan-out. | +| `/memory`, `/init`, `/context` | N/A | | + +### 3.5 Skills and slash commands + +| Feature | Status | Notes | +|---|---|---| +| `SKILL.md` skills, discovery scopes | Used | 7 shipped; registry covers user, project, plugin-cache paths. | +| Frontmatter beyond `name`/`description` (`allowed-tools`, `disallowed-tools`, `model`, `effort`, `context: fork`, `agent`, `background`, `paths`, `hooks`, `arguments`, `disable-model-invocation`, `user-invocable`) | Unused | The `pm` skill is a `context: fork` + `disable-model-invocation` candidate; `paths` gates language-specific skills. | +| `.claude/commands/*.md`, `$ARGUMENTS`, `!`shell``, `@file` | Used | `pm.md` only. | +| MCP prompts as `/flare:*` | Used | | +| `/skill-doctor`, `claude plugin eval` | Unused | Should back `agentflare skill eval` on Claude hosts. | +| `skillListingBudgetFraction`, `skillOverrides` | Partial | `skillOverrides` behind a cargo feature. | + +### 3.6 Subagents and orchestration + +| Feature | Status | Notes | +|---|---|---| +| `.claude/agents/*.md` | Partial | Apps project persona files there; workflow prompts bypass them. | +| `--agent <name>` (run the whole session as an agent), `--agents <json>`, `@agent-name` | Unused | Run each `auto-company` step as `claude -p --agent ceo-bezos`; each SDD role becomes an agent definition. | +| Frontmatter `tools`, `disallowedTools`, `model`, `permissionMode`, `maxTurns`, `skills`, `mcpServers`, `hooks`, `memory`, `effort`, `isolation: worktree`, `omitClaudeMd`, `initialPrompt`, `background` | Unused | Everything `RoleSpec` (§5) needs already exists as agent frontmatter. | +| Built-in `Explore`, `Plan`, `general-purpose` | Unused | The review-analyst prompt re-implements `Explore`. | +| Agent teams, `SendMessage`, `TeammateIdle`, `crossSessionInbound` | Unused | Decide the source of truth when Claude spawns its own team inside an agentflare job; agentflare's `message` tool and session registry should ingest `TeammateIdle`/`TaskCompleted`. | +| `/subtask`, fork mode | Unused | | +| Background agents, `claude agents`, `disableAgentView` | Unused | agentflare jobs are the durable equivalent. | +| Workflows tool, `/loop`, scheduled tasks | Unused | `flare-workflow` is agentflare's own engine; interop by letting a Claude workflow call `mcp__flare__workflow`. | +| Plan mode | Unused | Maps to `submit_plan`/`approve_plan`; `plansDirectory` is where Claude writes the plan file. | +| Worktrees (`--worktree`, `isolation: worktree`, `WorktreeCreate`) | Unused | agentflare provisions worktrees itself; document the nesting. | +| Checkpoints, `/rewind`, `fileCheckpointingEnabled` | N/A (own) | `agentflare git rewind` and shim snapshots are the universal equivalent. | + +### 3.7 MCP + +| Feature | Status | Notes | +|---|---|---| +| stdio and Streamable HTTP server | Used | | +| Scopes: user (`claude mcp add -s user`), project `.mcp.json` (Apps only) | Partial | A checked-in `.mcp.json` for the repo makes agentflare available to any collaborator without `init`. | +| Resources | Partial | `agentflare://sessions`, `agentflare://nudges`. Items, artifacts, memory facts and docs are natural resources (`@flare:item/123`). | +| Prompts | Used | | +| Tool search / deferred tools | Partial | agentflare's `tool(search|execute)` gateway is its own deferral layer and has fought Claude's native `ToolSearch` before (`fix: stop usetsearch blocking every native ToolSearch call`). Consider `alwaysLoad` and `_meta["anthropic/maxResultSizeChars"]` annotations instead. | +| `claude/channel` push messages (`--channels`, `channelsEnabled`) | Unused | Push inter-agent messages into a live session; retire the `Stop`-block path where available. | +| `claude mcp serve` | Unused | Turns Claude Code into a tool server any other agent can call: the cleanest way to give non-Claude agents a Claude worker. | +| `headersHelper`, OAuth, `ws` transport | Unused | Needed for the daemon to serve remote sessions. | +| Auto-background (>2 min), `MCP_TIMEOUT`, idle timeouts | Unused | `pr_wait` (60-120s) sits under the 2-minute auto-background threshold on purpose; document it. | + +### 3.8 Plugins + +| Feature | Status | Notes | +|---|---|---| +| `.claude-plugin/plugin.json`, marketplace | Unused | agentflare ships `.codex-plugin/plugin.json` and a Cline plugin but no Claude plugin, so hooks, rules, skills, agents and MCP are installed by editing user files. A plugin bundles them, versions them, `enabledPlugins` toggles them, and it is the only path under `strictPluginOnlyCustomization`. | +| Components: `skills/`, `agents/`, `hooks/hooks.json`, `.mcp.json`, `.lsp.json`, `monitors/monitors.json`, `bin/`, `settings.json` | Unused | `monitors` and `bin/` (PATH shims) map onto agentflare's dashboard signals and its PATH shim. | +| `claude plugin validate|eval` | Unused | | + +### 3.9 Sessions, context and cost + +| Feature | Status | Notes | +|---|---|---| +| Transcript parsing for cost | Used | Use `result.usage` from stream-json for jobs so cost survives `cleanupPeriodDays`. | +| `/compact [instructions]`, auto-compact, `autoCompactWindow` | Unused | For long jobs, send `/compact <focus>` over `--input-format stream-json` before context fills. | +| Session names, fork, `--from-pr`, `claude project purge`, `CLAUDE_CODE_PROJECT_DIR_NAME` | Unused | | +| Structured transcript access `claude -p --resume <id> --output-format json` | Unused | Documented alternative to parsing `.jsonl` (internal format, may break). | +| `/context`, `/cost`, `/usage`, `/insights` | N/A | `agentflare cost`, `insights`. | +| Usage polling via `.credentials.json` and an undocumented beta endpoint | Used, fragile | `claude setup-token`, or the `StopFailure` hook, are the supported signals. | + +### 3.10 Cloud, CI and integrations + +| Feature | Status | Notes | +|---|---|---| +| Claude Code on the web, `SessionStart` container caching, Routines, `--cloud`, `remote.defaultEnvironmentId` | Partial | Only this repo's own `.claude/hooks/session-start.sh` (installs lean-ctx, prefetches crates). Daemon jobs could target cloud sessions via Routines. | +| GitHub Action (`anthropics/claude-code`, `@claude`) | Unused | `.github/workflows` has no Claude job. A label-triggered `agentflare work` Action would complement `flare_git pr_wait`. | +| Remote Control, Slack Claude Tag | Unused | Overlaps with `message` + dashboard; `channel_send` is outbound only, Telegram is the only inbound chat. | +| Bedrock/Vertex/Foundry, `ANTHROPIC_BASE_URL`, OTEL | Unused | `flare-proxy` exposes an Anthropic-compatible endpoint but nothing points Claude Code at it. | +| Cowork | Partial | Host alias and `CLAUDE_CODE_IS_COWORK` detection only. | + +### 3.11 Agent SDK + +| Feature | Status | Notes | +|---|---|---| +| `query()` options: `agents`, `hooks` (in-process), `canUseTool`, `permissionPromptTool`, `systemPrompt`/`appendSystemPrompt`, `settingSources`, `mcpServers` (in-process servers), `outputFormat`/`jsonSchema`, `resume`/`forkSession`, streaming input, `sandbox`, `plugins`, `thinking`, `effort`, `abortController` | Unused | agentflare is Rust; the SDK is Node/Python. The CLI flags in §3.1 cover most of it. A thin Node sidecar (like the browser sidecar) would unlock `canUseTool` callbacks and in-process hooks without a process per event. | + +--- + +## 4.

Codex `exec --json`, Gemini `--output-format json` and OpenCode `run + --format json` exist upstream and are not mapped (`json_output_args` + covers 2 of 6 headless agents). +2.

Turn/budget caps: Claude only. `hard_cap`/`idle_timeout` is the universal + cap, but a cap hit is not surfaced as a typed outcome. +5. Permission postures are not equivalent (Codex `--full-auto` keeps its + sandbox; Claude skip-permissions removes every gate). Prefer each agent's + sandboxed-auto mode where one exists and document the difference. +6. Only Claude gets hook-pushed messages (`host_injects_context`); other + hosts see messages only when they happen to call an agentflare tool. +7.

Claude-Code-style features worth building universally + +Ranked by leverage. Each names the universal mechanism agentflare already has. + +| Feature (Claude Code) | Universal mechanism in agentflare | Status | Size | +|---|---|---|---| +| Role definitions (subagent frontmatter: tools, model, permission mode, max turns, skills, memory, system prompt) | A `RoleSpec` compiled per agent by the registry: `--agent`/`--agents` + `--allowedTools` + `--permission-mode` + `--append-system-prompt-file` for Claude; `--sandbox`/approval policy + system prompt file for Codex; `--yolo` + prompt for Gemini; `.cursor/rules` + `--force` for Cursor; system prompt only for the rest. Personas in `apps/*/personas` become the first RoleSpecs. | Not started | M | +| Hooks (PreToolUse deny, PostToolUse evidence, Stop messaging) | Run the hook pipeline inside the MCP gateway (`tool(execute)`) so any agent that routes tool calls through agentflare gets the branch guard, completion gate, coaching and messages; keep native hooks where the host has them (`mcp_tool` hooks on Claude make this one code path). | Partial (gateway exists, hooks not run in it) | M | +| Structured output (`--json-schema`) | One schema per role; `--json-schema` on Claude, JSON-mode flags on Codex/Gemini/OpenCode, validating retry for agents without one. Removes marker parsing everywhere. | Not started | M | +| Permission modes / tool policy | `RoleSpec.tools` compiled to `--allowedTools`/`--disallowedTools` (Claude), approval policy (Codex), `--auto` deny list (OpenCode), and to the gateway's allow-list for everyone else; `plan` mode wired to `submit_plan`/`approve_plan`. | Not started | M | +| Compaction survival (`PostCompact`, `/compact`) | agentflare-side transcript summary written to memory on job checkpoints and re-injected on `SessionStart source=compact`/`PostCompact` (Claude) or on the next prompt-submit hook (Cursor/Codex). Replaces the no-op `optimize context`. | Regressed | M | +| Skills | Registry + intent injection already universal where a prompt hook exists; for hook-less agents inject via the `skill` tool result and rules files. | Mostly done | S | +| Memory (auto memory bridge) | agentflare memory is universal; add import/export with Claude's `MEMORY.md`. | Partial | S | +| Session naming and addressability | Name every headless session `<item>:<role>:<round>` (`--name` on Claude, session ids elsewhere) and store it on the item so transcripts, cost and resume are one lookup. | Not started | S | +| Push messaging | `--channels` on Claude; polling delivery piggybacked on gateway results elsewhere (exists). | Partial | S | +| Failover on API errors | `StopFailure` hook on Claude; stdout classification elsewhere (exists). | Partial | S | +| Checkpoints / rewind | `agentflare git rewind` + snapshots. | Done | — | +| Plan mode | `submit_plan/approve_plan` + `--permission-mode plan` during planning. | Partial | S | +| Cost and status visibility | Dashboard is universal; status line is Claude-only; Cursor/OpenCode have status surfaces worth wiring. | Partial | S | +| Scheduled work (Routines, `/loop`) | `agentflare-jobs` + daemon: add `agentflare job schedule` (cron) so Claude is not the only timer. | Partial | M | +| PR steward | `flare_git pr_wait` + `check_merge` cover the poll; a `pr_watch` job that re-dispatches on CI failure or review comments completes it for every agent. | Partial | M | +| Plugins | One manifest generating `.claude-plugin/`, `.codex-plugin/` and the Cline plugin. | Not started | M | + +--- + +## 6. Roadmap + +**P0: make the headless worker build on Claude Code** + +1. Fix the `--output-format` collision and the last-line fallback (§2.3); + add a live-shaped test; verify `agent_sessions` gets a session id. +2. Introduce `RoleSpec` in `build_extra_args` (`src/cli/work.rs:241`) and + `real_agent_send_hook` (`src/work_item_pipeline.rs:725`); registry gains + `role_args(agent, &RoleSpec)`, Claude first: `--append-system-prompt-file`, + `--allowedTools`/`--disallowedTools`, `--permission-mode`, `--effort`, + `--name`, `--json-schema`. +3. Replace marker parsing in the SDD loop with schema verdicts; parse the + full stream-json `result` (usage, `num_turns`, `subtype`). +4. Job-scoped `--settings` and `--mcp-config` files generated under the + worktree (Apps already do the `.mcp.json` half); stop depending on the + user's `~/.claude` for jobs. Keep the plugin path (§6.10) as the fallback + for `disableSideloadFlags` environments. +5. Run personas as agents: `claude -p --agent <persona>` per step, or + `--agents` JSON; rewrite `apps/auto-company/workflow.json` prompts. + +**P1: hooks, settings and hygiene** + +6. `SessionStart` reads `source`; add `PostCompact` re-injection; delete or + implement `PreCompact`; fix README/AGENTS.md wording for `optimize context`. +7. Replace `--mode` with `--permission-mode` in `run_launch_env`. +8. Honour `CLAUDE_CONFIG_DIR` in `src/paths.rs`; make auth isolation use it + instead of `HOME`; make `statusLine` writes additive; make `uninstall` + remove everything `init` wrote. +9. Add `PermissionRequest` (programmatic approvals), `StopFailure` + (failover), `Notification` (channel routing), `SubagentStop` (reviewer + evidence), `TaskCompleted` (item sync). Move per-event work to + `mcp_tool` hooks where the logic already lives in the MCP server. +10. Express the branch guard and destructive-command rules also as + `permissions.deny` in a project `.claude/settings.json`; set + `attribution.commit: false`. +11. Auto-memory bridge; `.claude/rules` with `paths:` for language-scoped rules. + +**P2: distribution and interop** + +12. Publish a Claude plugin and marketplace entry generated from the same + manifest as `.codex-plugin`. +13. `claude mcp serve` adapter so non-Claude agents can call a Claude worker; + `--channels` push delivery. +14. GitHub Action recipe (`agentflare work` on label) and a Routines recipe + for Claude Code on the web. +15.

The last flag wins, stdout became a multi-line stream-json transcript, `parse_json_reply` failed to parse it as one object, and every dispatch silently lost its session_id and cost — so the SDD loop's `--resume` between fix rounds never fired in real runs. - `headless_full_args` skips the registry's JSON-output flags whenever the caller already pins `--output-format` (any spelling, incl. `--stream-json`). - `parse_json_reply` falls back to the final line when the whole stdout is not a single JSON object, so both output shapes yield session and cost. - `agentflare run --mode` forwarded a bare `--mode`, which Claude Code rejects; `agent_registry::mode_flag` maps it to `--permission-mode` for Claude Code and keeps the pass-through for other agents. Roadmap P0 item 2, first slice: `agent_registry::role` introduces `RoleSpec` (system prompt, allowed/disallowed tools, permission mode) and `compile_role(agent, &spec)`. Claude Code compiles to `--append-system-prompt`, `--allowedTools`, `--disallowedTools` and `--permission-mode`; every other agent gets an empty argv and the identity folded into the user prompt via `prompt_with_system_fallback`, never an unconfirmed flag. The SDD loop (`work_item_pipeline/roles.rs`) now gives each dispatch a role: implementer keeps every tool, the analyst and the reviewers lose the editing tools (Bash stays for verification), the judge also loses the shell. Resume args still lead the argv; a mid-flight correction still leads the prompt. Docs: README and AGENTS.md no longer describe `optimize context` as PreCompact-driven compaction (the hook is inert); the audit's roadmap and bug list record what landed here.

The card now says GitHub is blocking the merge until a review lands, whether an approving review is required or a reviewer requested changes (AwaitingReview and CiGreenMerge::BlockedOnReview now carry changes_requested), links the PR's review, and keeps the Approve button only while the label is also missing. The review card has its own once-per-item key so the plain label card is still sent once the review lands with the label absent. --- src/mcp_server/item_status.rs | 2 +- src/mcp_server/tests/item_force_tests.rs | 1 + src/supervisor.rs | 8 +- src/supervisor/merge.rs | 41 ++++- src/supervisor/notify.rs | 220 +++++++++++++++++++---- src/supervisor/tests/auto_merge_tests.rs | 4 +- src/worktree/mod.rs | 13 +- src/worktree/mod_tests.rs | 17 +- 8 files changed, 258 insertions(+), 48 deletions(-) diff --git a/src/mcp_server/item_status.rs b/src/mcp_server/item_status.rs index ee1648c51..7fd71df3a 100644 --- a/src/mcp_server/item_status.rs +++ b/src/mcp_server/item_status.rs @@ -42,7 +42,7 @@ fn pr_status_summary( crate::worktree::PrCiStatus::Passing { number, labels, .. } => { ("passing", Some(number), vec![], labels) } - crate::worktree::PrCiStatus::AwaitingReview { number, labels } => { + crate::worktree::PrCiStatus::AwaitingReview { number, labels, .. } => { ("awaiting_review", Some(number), vec![], labels) } crate::worktree::PrCiStatus::Behind { number, .. } => { diff --git a/src/mcp_server/tests/item_force_tests.rs b/src/mcp_server/tests/item_force_tests.rs index 9ee7460f1..d00b61e8b 100644 --- a/src/mcp_server/tests/item_force_tests.rs +++ b/src/mcp_server/tests/item_force_tests.rs @@ -253,6 +253,7 @@ fn a_passing_pr_is_not_evidence_unless_the_caller_is_on_its_pushed_branch() { let awaiting_review = PrCiStatus::AwaitingReview { number: 8, labels: vec![], + changes_requested: false, }; assert!( branch_gate(true, awaiting_review) diff --git a/src/supervisor.rs b/src/supervisor.rs index 3aaf9a1f8..456c0bb94 100644 --- a/src/supervisor.rs +++ b/src/supervisor.rs @@ -1589,7 +1589,11 @@ fn handle_pr_status( // repair labels cleared, the approval gate surfaced (the whole point: // this used to read as `Pending` and never reached the gate), and // CodeRabbit findings still repaired while it waits. - crate::worktree::PrCiStatus::AwaitingReview { number, labels } => handle_ci_green( + crate::worktree::PrCiStatus::AwaitingReview { + number, + labels, + changes_requested, + } => handle_ci_green( mcp, queue, auth_conn, @@ -1597,7 +1601,7 @@ fn handle_pr_status( item, number, &labels, - CiGreenMerge::BlockedOnReview, + CiGreenMerge::BlockedOnReview { changes_requested }, label_id_by_name, folder_path, repo_root, diff --git a/src/supervisor/merge.rs b/src/supervisor/merge.rs index 0ad7593c1..56909a195 100644 --- a/src/supervisor/merge.rs +++ b/src/supervisor/merge.rs @@ -15,7 +15,9 @@ pub(super) enum CiGreenMerge<'a> { /// verdict was made on.

The direct merge_if_approved path stays as the fallback when the repo has auto-merge off or GitHub refuses to arm it (a PR it could merge right now), and promotion of merged items stays in the sweep. Auto-merge is disarmed again when findings appear or the label is removed, keeping item #628's invariant. The batch GraphQL query now also fetches the PR node id, autoMergeRequest and the merge-queue flags; a base branch with a merge queue never reads "clean", so green required checks on a queue-enabled branch count as Passing instead of Pending forever, and an enqueued PR waits. The merge method comes from the repo's allowed methods (GET /repos, cached with repos::settings: squash, then merge, then rebase) instead of a hard-coded squash. GraphQL mutations now get the same write spacing as REST writes.

A 304 costs no primary rate-limit budget, so polling unchanged PRs, issues and check runs every sweep tick no longer eats the 5,000/hour allowance. The cache lives with the per-host throttle state (so mock servers in tests never share entries), is capped at 1024 entries evicted oldest-first and 512 KiB per body, and drops an entry whenever a response comes back without a validator. The secondary-rate-limit backoff still refuses calls before any network or cache lookup, since a cached body is only known current once the server has confirmed it, and the 401 token refresh retries through the same conditional path. The test mock server now records request headers so the conditional headers can be asserted. --- src/github/client.rs | 167 +++++++++++++++++++++++++++++++++++-- src/github/etag_cache.rs | 136 ++++++++++++++++++++++++++++++ src/github/mod.rs | 1 + src/github/test_support.rs | 25 +++++- 4 files changed, 319 insertions(+), 10 deletions(-) create mode 100644 src/github/etag_cache.rs diff --git a/src/github/client.rs b/src/github/client.rs index 8f621f2ea..358baeb6e 100644 --- a/src/github/client.rs +++ b/src/github/client.rs @@ -2,10 +2,13 @@ //! with no credential, maps status codes to `GitHubError`, and applies //!

item_done then flips it ready for review (GraphQL markPullRequestReadyForReview, using the node id the create already returned) and records metadata.pr.ready. Repositories that refuse draft PRs (GitHub's 422) get an ordinary PR instead. Nothing stalls on a draft: the CI-status paths (REST and batched GraphQL, which now fetches isDraft) report a new PrCiStatus::Draft before any check state, and the review sweep re-runs the ready flip for an in-review item whose flip never landed. A draft the item already records as flipped was converted back by a human and is held: not re-flipped, not merged, and not self-repaired, since Draft is decided before Failing/Passing.

A disarm GitHub refused used to clear the sweep's arming record anyway, leaving nothing to retry; now the record stays until GitHub confirms the disarm. And because sweep-time reconciliation alone cannot stop GitHub merging a head that was pushed and went green between two ticks, the sweep now posts a per-commit status (context agentflare/judged) on the exact head it armed auto-merge on. A repo that requires that context in branch protection gets a merge-time gate: a later push is a new sha without the status, so GitHub waits for the sweep to judge it. Repos that don't require it see an informational status. --- src/github/actions.rs | 54 ++++++++++++++++++++++++ src/supervisor/auto_merge.rs | 41 +++++++++++------- src/supervisor/merge.rs | 40 ++++++++++++++++++ src/supervisor/tests/auto_merge_tests.rs | 37 +++++++++++++--- 4 files changed, 151 insertions(+), 21 deletions(-) diff --git a/src/github/actions.rs b/src/github/actions.rs index c643a3767..24b2c4073 100644 --- a/src/github/actions.rs +++ b/src/github/actions.rs @@ -95,6 +95,35 @@ pub fn list_check_runs( /// status was still pending or red.

Arm it only when something stops that: the base branch merges through a merge queue (the queue's own merge_group CI run is the gate, and a direct merge is refused there anyway), or the base branch's protection or rulesets require the agentflare/judged status the sweep stamps on every judged head. Otherwise the sweep merges directly, pinned to the judged head, as before; a review-blocked PR on such a branch waits for the review and merges on the next tick. repos::required_status_contexts reads branch protection and rulesets for a branch once per process (an unprotected or unreadable branch reads as "nothing required"). AutoMergeRef carries the PR's base branch and merge-queue flag from the same fetch as the CI verdict (GraphQL baseRefName/isMergeQueueEnabled, REST base.ref). --- src/github/graphql.rs | 11 +- src/github/repos.rs | 134 ++++++++++++++++++ src/supervisor/merge.rs | 66 ++++++++- src/supervisor/tests/auto_merge_tests.rs | 171 ++++++++++++++++++++--- src/worktree/mod.rs | 35 +++-- src/worktree/mod_tests.rs | 1 + 6 files changed, 374 insertions(+), 44 deletions(-) diff --git a/src/github/graphql.rs b/src/github/graphql.rs index fa01852fa..15cbf4a86 100644 --- a/src/github/graphql.rs +++ b/src/github/graphql.rs @@ -71,6 +71,9 @@ pub struct BatchPrData { /// review it -- agentflare opens every PR as one and is expected to have /// flipped it by the time the item is in review. pub is_draft: bool, + /// `baseRefName`: the branch this PR merges into, whose protection + /// decides whether arming auto-merge is safe. + pub base_ref: Option<String>, } /// One aliased sub-query for PR `number` -- `pr<number>` is a valid GraphQL @@ -84,7 +87,7 @@ fn pr_alias(number: u64) -> String { fn pr_subquery(number: u64) -> String { format!( "{}: pullRequest(number: {number}) {{ id state merged mergeable mergeStateStatus \ - isDraft reviewDecision headRefOid \ + isDraft reviewDecision headRefOid baseRefName \ isMergeQueueEnabled isInMergeQueue autoMergeRequest {{ enabledAt }} \ labels(first: 20) {{ nodes {{ name }} }} \ commits(last: 1) {{ nodes {{ commit {{ statusCheckRollup {{ state contexts(first: 100) {{ \ @@ -230,6 +233,7 @@ fn parse_batch_pr(node: &serde_json::Value) -> BatchPrData { merge_queue_enabled: node["isMergeQueueEnabled"].as_bool().unwrap_or(false), in_merge_queue: node["isInMergeQueue"].as_bool().unwrap_or(false), is_draft: node["isDraft"].as_bool().unwrap_or(false), + base_ref: string(&node["baseRefName"]), } } @@ -454,7 +458,7 @@ mod tests { 200, r#"{"data":{"repository":{ "pr8":{"id":"PR_kwDOAbc","merged":false,"mergeable":"MERGEABLE","mergeStateStatus":"BLOCKED", - "isMergeQueueEnabled":true,"isInMergeQueue":false, + "baseRefName":"main","isMergeQueueEnabled":true,"isInMergeQueue":false, "autoMergeRequest":{"enabledAt":"2026-09-24T00:00:00Z"}, "labels":{"nodes":[]},"commits":{"nodes":[]}}, "pr9":{"id":"PR_kwDOAbd","merged":false,"mergeable":"MERGEABLE","mergeStateStatus":"CLEAN", @@ -470,7 +474,10 @@ mod tests { assert!(!out[&8].in_merge_queue); assert!(!out[&9].auto_merge_enabled); assert!(!out[&9].merge_queue_enabled); + assert_eq!(out[&8].base_ref.as_deref(), Some("main")); + assert_eq!(out[&9].base_ref, None); let sent: serde_json::Value = serde_json::from_str(&server.requests()[0].body).unwrap(); + assert!(sent["query"].as_str().unwrap().contains(" baseRefName ")); assert!( sent["query"] .as_str() diff --git a/src/github/repos.rs b/src/github/repos.rs index 081d335a1..c9dd30a6d 100644 --- a/src/github/repos.rs +++ b/src/github/repos.rs @@ -284,6 +284,96 @@ pub fn delete_merged_pr_branch( delete_ref_if_at(client, node_id, &head.git_ref, &head.sha) } +/// The status-check contexts `branch`'s protection requires before a merge, +/// from both places GitHub keeps them: the classic branch-protection rule +/// (`GET /branches/{branch}`, whose `protection.required_status_checks` +/// lists them even when the dedicated protection endpoint needs admin +/// scope) and repository rulesets (`GET /rules/branches/{branch}`, each +/// `required_status_checks` rule naming its contexts).
