The session replaced the deferred Codex routing boundary with backup-first hook management, surgical uninstall behavior, privacy-safe status and doctor output, and focused test and documentation coverage. *** ## Deliverables ### Files Created | File | Purpose | Lines | | ------------------------------------------------------------------------------------------------------------- | -------------------------------------------- | ----- | | `apps/cli/tests/codexInstaller.test.js` | Focused Codex installer and posture coverage | \~260 | | `.spec_system/specs/phase10-session02-codex-hook-install-uninstall-and-diagnostics/IMPLEMENTATION_SUMMARY.md` | Session closeout summary | \~80 | ### Files Modified | File | Changes | | ------------------------------------------- | -------------------------------------------------------------------------------- | | `apps/cli/src/installers/codex.js` | Added Codex hook backup, merge, install, uninstall, and posture logic | | `apps/cli/src/commands/init.js` | Replaced deferred Codex summary with real install guidance | | `apps/cli/src/commands/uninstall.js` | Added backup restore and managed-hook removal summaries | | `apps/cli/src/commands/doctor.js` | Added Codex hooks validity, counts, and trust-review guidance | | `apps/cli/src/commands/status.js` | Added compact Codex posture output | | `apps/cli/src/lib/localFiles.js` | Added Codex directory resolution helper support | | `apps/cli/src/lib/providerPosture.js` | Added Codex posture formatting and count labels | | `apps/cli/tests/cliProvider.test.js` | Updated provider selection expectations for real Codex install behavior | | `apps/cli/tests/cliRuntime.test.js` | Expanded runtime coverage for Codex init, install, uninstall, doctor, and status | | `apps/hooks/tests/codexHookMap.test.js` | Verified the Codex hook template remains installable | | `apps/cli/README_cli.md` | Documented Codex install, uninstall, and diagnostics behavior | | `apps/hooks/README_hooks.md` | Documented Codex hook map readiness and trust-review boundaries | | `.spec_system/state.json` | Marked the session complete in project state | | `.spec_system/PRD/phase_10/PRD_phase_10.md` | Updated phase progress tracking and session status | | `.spec_system/PRD/PRD.md` | Updated the master Phase 10 status map | | `package.json` | Incremented the patch version | *** ## Technical Decisions 1. **Backup-first installs**: Preserve the first raw Codex hooks file before writing managed hooks so uninstall can restore user state when possible. 2. **Compact diagnostics**: Report labels, counts, and trust-review guidance only, avoiding raw hook bodies or sensitive configuration disclosure. *** ## Test Results | Metric | Value | | -------- | -------- | | Tests | 3 suites | | Passed | 3 suites | | Coverage | N/A | *** ## Lessons Learned 1. Codex hook handling needs surgical ownership checks to avoid removing user-managed entries. 2. Session closeout files are part of the release contract and should be updated together with the code changes. *** ## Future Considerations Items for future sessions: 1. Complete Phase 10 server ingest so Codex lifecycle events flow into heroes and missions. 2. Finish Phase 10 web awareness so Codex labels and filters are visible in the cockpit. *** ## Session Statistics * **Tasks**: 23 completed * **Files Created**: 2 * **Files Modified**: 16 * **Tests Added**: 1 * **Blockers**: 0 resolved --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://faction-os.gitbook.io/faction-os-docs/.spec_system/archive/sessions/phase10-session02-codex-hook-install-uninstall-and-diagnostics/implementation_summary.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
