docs(cli): a seat you attach yourself is private; say what it reaches - #2356
Conversation
…d what that reaches Every seat the web app or the daemon sets up is public (sandboxed, none of your own tools). A seat attached with `commonly agent attach` with no --env, or with an env file that declares no sandbox, is private: it runs as you with no sandbox, reaches your whole machine (files, shell tools, your own MCP servers and their logged-in sessions, skills, account connectors; Codex without approvals), and takes instructions from anyone who can @mention it in the pod. The wrapper doc now says so in a section of its own, and the README's manual path and the OpenCode guide point at it. Walked 2026-10-20. Also restores, per Vera's note on #2349, that the DeepSeek model was walked through an OpenAI-compatible endpoint as well as DeepSeek's API.

Docs gate — #2356 at 5fe01f43da73d4effab2d0a38990f0417c40aaab
One commit, docs only: README.md (+1 sentence), docs/agents/LOCAL_CLI_WRAPPER.md (the new section), docs/cli/opencode.md (pointer + the DeepSeek note). No non-.md path in the diff. Claims checked against origin/main 79600819, which carries #2354 as 8fbbfca6.
What holds
- (2) A self-attached seat is private.
buildDefaultEnvironment(cli/src/commands/agent.js:491) returns{ mcp, skills }and declares nosandbox. The onlyseatBaseline(..., { sandbox: true })in that file is the bootstrap record at:391; the self-attach path writes the environment without it. An env file with nosandboxblock is the same thing towithDefaultSandbox, which treats a missing block, an empty one andmode: 'none'alike. - (3) What a private seat reaches.
--setting-sources '',--disable-slash-commands,--strict-mcp-configand--permission-mode dontAskall live insidebuildPublicClaudePolicyArgs(adapters/claude.js:251-257), which is spread only on the two public branches — so the private branch loads your settings and MCP servers, and your real HOME. The public seat's own HOME isoutput.HOME = state.statePath(:209), a per-identity 0700 directory. Codex: the private branch is['--dangerously-bypass-approvals-and-sandbox'](adapters/codex.js:432), and the public branch takes--ignore-user-config, which is what makes "a public Codex seat ignores your~/.codex/config.toml" true. - (4) The attach refusal.
agent.js:561—const isPublic = Boolean(pod?.publicRead) || Boolean(pod?.communityListed);— both halves of "a pod anyone can read or one listed in Community", and the gate refuses the seat that declares no enforced sandbox, so narrowing the sentence to a private seat is right. - The skills sentence is consistent with #2354 as merged: a public seat doesn't read yours, and does get the ones the seat declares.
- Both pointers resolve: the heading is
### Public and private seatsatLOCAL_CLI_WRAPPER.md:58, so the slug both links use is correct, and../agents/LOCAL_CLI_WRAPPER.mdfromdocs/cli/is the right relative path. - The DeepSeek note claims no more than the walks: two runs of the same model, both answering an @mention through the Commonly tool, and the "none has been walked yet" sentence is narrowed rather than dropped.
Defect — the section's first sentence is false for the one adapter that cannot be confined
"Every seat that the web app or the daemon sets up is public: its environment declares
"sandbox": { "trust": "public" }."
seatBaseline adds that block only when the adapter is in ADAPTERS_WITH_DEFAULT_SANDBOX (cli/src/lib/default-environment.js:46), which is {claude, codex, opencode, qwen}. pi is excluded on purpose — the comment above COMMONLY_DEFAULT_SANDBOX says "A pi seat must never be handed this block: it fails closed on a declared sandbox rather than run under a spec it cannot honour" — and the exclusion is pinned by a test named for it (cli/__tests__/default-environment.test.mjs:40, ['claude','codex','opencode','qwen']).
So a page- or daemon-set-up pi seat gets { mcp: [commonly] } and no sandbox — which is, by this section's own definition two paragraphs later, a private seat. pi is reachable on both paths the sentence names: it is third in BOOTSTRAP_ADAPTER_DETECT_ORDER = ['claude', 'codex', 'pi'] (agent.js:154), so the page's own command picks it when neither claude nor codex is on PATH, --adapter pi selects it directly, and the daemon's derive calls the same seatBaseline (daemon-supervisor.js:199).
Carried to its mint, because a reachability claim needs it: serverAdapterBindingRefusal throws before the record at :391 is built unless the installation already declares runtimeAdapter: 'pi', and adapterForRuntimeBinding (backend/services/grantBrokerConfinement.ts:135) accepts any adapter string, so that declaration exists once an owner has run attach pi for the seat. Narrow, and not hypothetical.
For pi the sentence is not merely inaccurate, it is unachievable: assertNoSandboxDeclared (adapters/pi.js:306) refuses to start a seat whose trust resolves to public — "pi has no enforced sandbox; do not attach a pi seat to a stranger-readable pod". Handing a pi seat the block the sentence promises would stop it booting.
Held on direction, not on pedantry. Every other claim in the section errs toward telling the reader they are exposed; this one tells them they are confined, and it is the sentence a reader checks first — the page says public, so the seat is sandboxed. For a pi seat that is wrong, deliberately and by test. The guide went to an outside user today, which is the reason this is worth a clause rather than a footnote.
Precision note, not a defect
"the listener pre-approves only Commonly's tools" — the pre-approval is mcp__<name>__* for every server declared in env.mcp (adapters/claude.js:637-641), not only commonly. That reads as only-Commonly because the default environment declares only Commonly; a seat whose --env declares the person's own server gets that server's tools pre-approved too, and then the permissions.allow step is unnecessary. The instruction stays correct for the case the paragraph is actually about — servers that live in the person's own config rather than the seat's env spec — so this is wording, and it errs toward an extra step rather than a missing one.

GATE: HOLD
…s declared servers Vera on #2356: "every seat the web app or the daemon sets up is public" is false for pi, which seatBaseline never hands the sandbox block (ADAPTERS_WITH_DEFAULT_SANDBOX excludes it, and adapters/pi.js refuses a public trust). The sentence now names the four adapters that get it and says a pi seat is always private. Also: the listener pre-approves the tools of every server in the seat's environment, by default only Commonly's; tools from the person's own ~/.claude.json are the ones that need permissions.allow.

Re-gate — #2356 at 329ef9aa53c6577ba332e264d69816d2dde7394f
My HOLD at 5fe01f43 is an ancestor; one commit since, docs/agents/LOCAL_CLI_WRAPPER.md only, +2 −2. README.md and docs/cli/opencode.md are blob-identical to the head I held, so everything I verified there carries forward untouched.
The held defect is closed, and the replacement matches the code
"A Claude Code, Codex, OpenCode or Qwen Code seat that the web app or the daemon sets up is public … A pi seat is the exception. pi can't be sandboxed, so a pi seat never gets that block and is always private, however it was set up."
The four named adapters are exactly ADAPTERS_WITH_DEFAULT_SANDBOX (cli/src/lib/default-environment.js:46), the set seatBaseline gates the public block on, and the set cli/__tests__/default-environment.test.mjs:40 pins by name. pi's exclusion is the deliberate one that comment describes, and assertNoSandboxDeclared (adapters/pi.js:306) is why it cannot be reversed.
I checked the whole registry rather than only the adapter I named: it is {stub, claude, codex, pi, opencode, qwen}, so stub is the one other member outside the public set. Leaving it out of a user-facing doc is right — stub.detect() returns (builtin) and stub.spawn() returns a canned string, so a stub seat has no sandbox and no capability; there is nothing for a reader to be exposed by.
The precision note is closed too
"the listener pre-approves the tools of the servers declared in the seat's environment (by default, only Commonly's). Tools from servers in your own
~/.claude.jsonneed apermissions.allowentry in your~/.claude/settings.json…"
Three claims, three checks. The pre-approval is mcp__<name>__* built from env.mcp (adapters/claude.js:637-641). "By default, only Commonly's" is exact: defaultMcpServers returns [commonlyMcpServer()] and nothing else. And ~/.claude.json is the right file to name for the person's own servers, corroborated twice inside this repo — adapters/claude.js:173 reads join(homedir(), '.claude.json') as operatorConfigPath, and docs/MCP_INTEGRATION.md:172,181 documents it as where global MCP config lives. The remedy still points at ~/.claude/settings.json, which is where permissions.allow belongs and which a private seat loads, because the private branch passes no --setting-sources ''.
Nothing pinned the old sentence: no test under backend/__tests__, cli/__tests__, frontend/src or scripts references LOCAL_CLI_WRAPPER, so the rewrite left no stale fixture behind.
One nuance, not a defect
"always private, however it was set up" is the right claim for any pi seat that runs, and it is worth knowing why it is not simply "unsandboxed by default": an operator who hand-writes an env with sandbox.trust: public or a non-none mode for pi does not get a public pi seat, they get one that refuses to start — assertNoSandboxDeclared throws before the spawn. So the sentence's two readings ("pi is never confined" and "declaring confinement for pi achieves nothing") are both true, and the failure mode a reader could hit is a seat that will not boot rather than one that silently runs unconfined. That errs toward caution, which is the direction this section should err in.
Verdict
Both items I held on are fixed against the code they describe, the fix touches two lines and nothing else moved, and the rest of the PR is the text I verified at the previous head. No defect.
