The standalone CLI packs reviewed context without Fable, Memory, +Python, an API key, a model, or any third-party runtime dependency. + +**Source preview: 0.1.0-alpha.1.** Independently installable source, not an npm +release. `private: true` deliberately blocks accidental registry publication. +Real installation, discovery, installed CLI lifecycle and removal have been +validated in disposable Codex homes on Windows (versions below). Native +compaction/resume remains unvalidated; fixture hook events are not that evidence. + +## What works + +The deterministic packer retains whole redacted excerpts, source references, +constraints, failures, findings, test results, action records, approvals, +corrections, unknowns, and explicitly required evidence. It preserves paired +tool calls/results and their dependencies. Optional records are selected by +word overlap and recency under a complete JSON byte budget. Omitted records +remain explicit; protected material that does not fit causes an error. + +The CLI can deliberately stage one reduced, reviewed snapshot for a session, +read it back while its binding is valid, and revoke it. The optional Codex hook +announces a valid snapshot after native compaction or resume. The skill then +retrieves the snapshot as **tool data**, not as new developer instructions. + +This does **not** replace Codex's native compactor, rewrite rollout files, +automatically collect transcripts, or guarantee that nothing important is lost. +The packer cannot recover evidence that the supplied input never contained. +Historical approvals stay historical; a retained passing-test claim is not proof. + +## Try without installing a plugin + +Requirements: Node.js 18 or newer. Git is also required for stage/read/hook +binding checks. From this standalone directory or an extracted source archive: + +```sh +node examples/demo.mjs +npm test +npm run check +node bin/codex-context-keeper.mjs help +``` + +These commands require no dependency installation and use synthetic fixtures. +Tests create and remove disposable Git repositories; they do not use your +normal repository or credentials. + +For a local npm artifact (not publication): + +```sh +npm pack --ignore-scripts +``` + +The entire directory, including hidden manifests, can be copied to a separate +checkout. It imports nothing from Fable. While maintained in Fable, an additional +root test enforces byte parity between both copies of the shared packer and I/O +modules. Do not edit those copies independently. + +## Prepare an explicit reviewed input + +The input is `agoragentic.context-input.v1`, not a native transcript. It contains +`scope` (opaque project/repo/worktree/session IDs), `policy_revision`, `task` +(`goal`, exact `head_ref`, `required_ids`), `records`, and `upstream_omitted`. +Each record has `id`, `kind`, exact redacted `text`, text `sha256`, +`source: {id, revision}`, `evidence_refs`, and `requires` dependencies. Source +coordinates/hash are optional. Tool records require a paired `call_id` and an +explicit `effect`: `read_only`, `side_effect`, or `unknown`. + +A separate host-reviewed binding specifies the expected scope, policy revision, +Git head, source revision map, canonical input digest, and `budget_bytes` +(1,024 through 65,536). `examples/demo.mjs` shows the complete executable input +and binding. The exported `snapshotDigest(input)` computes the input fingerprint; +it does not approve or redact it. + +Use actual current source evidence and a session ID supplied by the host. Never +invent a host session ID or parse rollout files to discover one. The optional +startup hook below provides the current ID. Store private inputs and bindings +outside Git. Redaction, source authorization and correct record classifications +remain the owner's/trusted host's responsibility; this is not a secret scanner. + +```sh +node bin/codex-context-keeper.mjs pack --input INPUT.json --binding BINDING.json +``` + +Output is JSON on stdout. Review before saving or sharing; insufficiently +redacted input produces insufficiently redacted output. No file is changed. + +## Stage, read, revoke + +Use an absolute, **new dedicated private root** whose parent exists; the command +creates the directory and marker. Existing unmarked roots are rejected. Choose +a location outside repositories, synced folders, shared homes and backups where +possible. Outside-repository placement is an owner obligation, not enforced by +the CLI. Never point this at the normal Codex home or Memory database. + +The following uppercase values are placeholders to replace, not literal paths: + +```sh +node bin/codex-context-keeper.mjs stage --input INPUT.json --binding BINDING.json --root ABSOLUTE_PRIVATE_ROOT --cwd ABSOLUTE_WORKTREE --session HOST_SESSION_ID --reviewed REVIEWED_REDACTED +node bin/codex-context-keeper.mjs read --root ABSOLUTE_PRIVATE_ROOT --cwd ABSOLUTE_WORKTREE --session HOST_SESSION_ID --policy POLICY_REVISION +node bin/codex-context-keeper.mjs revoke --root ABSOLUTE_PRIVATE_ROOT --session HOST_SESSION_ID +``` + +PowerShell accepts the same commands on one line. Staging and revocation are +explicit local writes; obtaining a context pack does not authorize either one. +Only the reduced pack is stored, not the source input or a second transcript. +An existing session capsule is never overwritten: explicitly revoke and then +stage a fresh reviewed snapshot when replacement is required. + +TTL defaults to ten minutes; `--ttl-ms` permits 1,000 through 3,600,000. Expiry +prevents use but does not physically delete the file. `revoke` unlinks only the +named capsule, not unrelated data or backups. Root/capsule paths are local and +owner-controlled. See SECURITY.md before use on shared machines. + +Reads enforce session, canonical working directory, policy, expiry, committed +Git HEAD, integrity and data-only boundary checks. **An unchanged HEAD does not +prove that the worktree, external sources or permissions are unchanged.** Before +continuing actual work, revalidate those live conditions. No stored approval is +renewed by a matching hash. The fixed Git read uses no shell or network command. + +## Optional Codex plugin + +The portable root `plugin.json`, compatibility `.codex-plugin/plugin.json`, +`skills/`, `hooks/hooks.json`, and self-contained local marketplace are included. +Codex 0.159.2 installs the portable layout and discovers its skill, but does not +discover portable plugin hooks. For hooks on this version, prepare the supported +compatibility layout in a **new directory whose parent already exists**: + +```sh +node scripts/prepare-codex-plugin.mjs ./NEW_COMPATIBILITY_DIRECTORY +``` + +This copies the self-contained runtime, skill and compatibility manifest. It +omits the portable root manifest, refuses existing destinations and never +installs anything. Use that directory, not Fable's root marketplace, when you +explicitly choose to install: + +```sh +codex plugin marketplace add ./NEW_COMPATIBILITY_DIRECTORY +codex plugin add codex-context-keeper@codex-context-keeper-local +``` + +These two Codex commands change the selected Codex home's configuration. Review +and trust the installed hooks through Codex's supported interface before use; +installation alone does not grant hook trust. First use the disposable smoke +below. Neither the packer nor the preparation command installs or activates a +plugin. The original portable package also installs on 0.159.2; its missing hook +discovery is a separate runtime limitation, not a general installation failure. + +Hooks remain **off** unless the owner supplies all of these settings in the +Codex launch environment (values are placeholders): + +```powershell +$env:CODEX_CONTEXT_KEEPER_ENABLE = "1" +$env:CODEX_CONTEXT_KEEPER_ROOT = "ABSOLUTE_PRIVATE_ROOT" +$env:CODEX_CONTEXT_KEEPER_POLICY = "POLICY_REVISION" +``` + +The Bash equivalents are ordinary `export NAME=value` settings. These are not +credentials. Do not dump unrelated environment variables to find them. Unset +`CODEX_CONTEXT_KEEPER_ENABLE` or set it to `0` to disable the hooks; this does not +delete staged files. No normal Codex configuration is edited by this project. + +On startup the enabled hook emits the current host session ID, without reading +a transcript or creating a snapshot. After an explicit stage, `PreCompact` +checks availability without altering native compaction. On `SessionStart` with +`source: compact` or `resume`, a valid capsule produces only a fixed retrieval +pointer. Ask/use `$codex-context-keeper` to read the packet as data. A missing, +expired, revoked, changed or invalid capsule produces a notice, not a successful +restore claim. Known subagent events and unrelated events are ignored. + +The hook's additional context is developer-role material in Codex. Therefore it +never contains source excerpts, shell commands from retrieved text, or arbitrary +paths supplied by a packet. The local read command returns the actual excerpts +at the tool-data boundary. Prompt injection in those excerpts can still affect +a model; this design does not guarantee model instruction adherence. + +## Validation before wider use + +The included tests exercise the library, real CLI subprocesses, disposable Git +head changes, private local capsule lifecycle, malformed/bounded hook input, +default-off behavior, and manifest consistency. Hook events are fixtures, not a +native compaction/resume event. POSIX permission assertions do not validate +Windows ACLs. + +Run the real-host smoke from the standalone source or npm archive. Supply the +actual Codex executable path if it is not on PATH: + +```sh +node scripts/smoke-codex-install.mjs codex compatibility +node scripts/smoke-codex-install.mjs codex both +``` + +The smoke creates and removes disposable homes, local marketplaces and Git +repositories. It installs the actual payload, checks app-server skill and hook +discovery, runs the installed CLI and configured shell hook with synthetic +input, and tests policy/HEAD denial, revocation, removal and reinstallation. +It makes no model turns, copies no credentials, edits no hook trust records and +does not touch the normal Codex home. Hooks must remain `untrusted` during this +check. Any missing hook or discovery warning fails the selected layout's gate. + +Windows results on September 30, 2026: + +| Codex version | Portable layout | Prepared compatibility layout | +| --- | --- | --- | +| 0.142.5 | Install, discovery and lifecycle pass | Install, discovery and lifecycle pass | +| 0.159.2 | Install and CLI pass; hook discovery fails | Install, discovery and lifecycle pass | + +Thus `both` intentionally fails on 0.159.2. The `compatibility` selection checks +the supported path without claiming portable hooks work. Both paths use the +same runtime bytes; the portable manifest remains available for other hosts. + +Before enabling on real tasks, validate your host version in an isolated Codex +home, actual manual/automatic compaction and resume, Windows/macOS/Linux +behavior, independent worktrees, policy changes and deletion.
