***

## Setup (4 tasks)

Confirm prerequisites, current evidence, and the selected cross-package scope.

### Cross-package

* [x] T001 \[S1201] Verify Phase 12 Session 01 prerequisites, candidate ordering, and Session 02 dependency on the packaging decision (`.spec_system/PRD/phase_12/session_01_codex_plugin_packaging.md`)
* [x] T002 \[S1201] Review current Codex hook, config, and plugin requirement sources before any package files are created (`apps/hooks/README_hooks.md`)
* [x] T003 \[S1201] Inventory Phase 11 direct hook validation evidence, privacy boundaries, and unsupported live-step exceptions (`.spec_system/specs/phase11-session03-end-to-end-validation-and-integration-fixes/codex-e2e-validation-record.md`)
* [x] T004 \[S1201] Prepare isolated `CODEX_HOME`, `FACTIONOS_HOME`, cache, and docs-review plan so validation does not mutate real user state (`.spec_system/specs/phase12-session01-codex-plugin-packaging/implementation-notes.md`)

***

## Foundation (5 tasks)

Create the decision artifacts and map the branch criteria.

### Cross-package

* [x] T005 \[S1201] \[P] Create packaging decision record with criteria matrix, source references, proceed/defer branch, and no-overclaim fields (`.spec_system/specs/phase12-session01-codex-plugin-packaging/codex-plugin-packaging-decision.md`)
* [x] T006 \[S1201] \[P] Create validation plan for install, hook trust, cache refresh, uninstall, privacy review, and branch-specific fallback handling (`.spec_system/specs/phase12-session01-codex-plugin-packaging/codex-plugin-validation-plan.md`)
* [x] T007 \[S1201] \[P] Map direct user-level Codex hook baseline docs, installer behavior, diagnostics, and uninstall support (`apps/cli/README_cli.md`)
* [x] T008 \[S1201] \[P] Map reusable hook package assets, Codex hook map boundaries, and redaction rules for possible plugin reuse (`apps/hooks/README_hooks.md`)
* [x] T009 \[S1201] Define pass/fail decision gate so any plugin package is created only after all required criteria pass (`.spec_system/specs/phase12-session01-codex-plugin-packaging/codex-plugin-packaging-decision.md`)

***

## Implementation (10 tasks)

Evaluate the decision gate, implement the selected branch, and align docs.

### Cross-package

* [x] T010 \[S1201] Evaluate direct user-level Codex hooks against install, run, doctor, status, uninstall, and `/hooks` trust evidence (`.spec_system/specs/phase12-session01-codex-plugin-packaging/codex-plugin-packaging-decision.md`)
* [x] T011 \[S1201] Evaluate Codex plugin value for maintenance, distribution, trust review, reuse, and privacy without creating duplicate runtime paths (`.spec_system/specs/phase12-session01-codex-plugin-packaging/codex-plugin-packaging-decision.md`)
* [x] T012 \[S1201] Record final packaging decision with explicit release implications, known limitations, and Session 02 handoff (`.spec_system/specs/phase12-session01-codex-plugin-packaging/codex-plugin-packaging-decision.md`)
* [x] T013 \[S1201] Implement the selected branch artifact with schema-validated manifest inputs if packaging proceeds or explicit no-manifest deferral if it does not (`.spec_system/specs/phase12-session01-codex-plugin-packaging/codex-plugin-packaging-decision.md`)
* [x] T014 \[S1201] Update CLI docs so direct Codex hooks remain the supported baseline and plugin packaging is either documented or explicitly deferred (`apps/cli/README_cli.md`)
* [x] T015 \[S1201] Update hook package docs for plugin reuse boundaries, `/hooks` trust review, no trust bypass, and no raw payload storage (`apps/hooks/README_hooks.md`)
* [x] T016 \[S1201] Update hook contract docs if the selected branch changes supported install surfaces, examples, or deferral wording (`docs/api/event-api-hook-contracts.md`)
* [x] T017 \[S1201] Update developer workflow notes for the selected branch while preserving no hosted auth, telemetry, remote execution, or trusted-erasure claims (`docs/development.md`)
* [x] T018 \[S1201] Record plugin install, hook trust, cache refresh, and uninstall evidence or record why those checks are not applicable for deferral (`.spec_system/specs/phase12-session01-codex-plugin-packaging/codex-plugin-validation-plan.md`)
* [x] T019 \[S1201] Update implementation notes with command evidence, selected branch, docs touched, privacy review, and open questions closed or carried forward (`.spec_system/specs/phase12-session01-codex-plugin-packaging/implementation-notes.md`)

***

## Testing (4 tasks)

Run focused validation and repository hygiene for the selected branch.

### Cross-package

* [x] T020 \[S1201] Run focused CLI and hooks tests for any touched installer, provider posture, uninstall, hook map, or handler reuse behavior (`apps/cli/tests/codexInstaller.test.js`)
* [x] T021 \[S1201] Run plugin manifest or packaging validation if package files exist, otherwise verify no plugin-package validation is represented as passed (`.spec_system/specs/phase12-session01-codex-plugin-packaging/codex-plugin-validation-plan.md`)
* [x] T022 \[S1201] Run formatting, linting, `git diff --check`, ASCII/LF validation, and sensitive-string review for touched files (`package.json`)
* [x] T023 \[S1201] Finalize decision record, validation plan, implementation notes, and Session 02 release-readiness handoff (`.spec_system/specs/phase12-session01-codex-plugin-packaging/implementation-notes.md`)

***

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

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/phase12-session01-codex-plugin-packaging/tasks.md?ask=<question>&goal=<endgoal>
```

`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.
