## Task Description

Add a concise, cross-tool contributor/review instruction layer so Codex, Claude, Gemini, and GitHub Copilot can participate in the project without duplicating the full Agentic OS governance corpus into every tool-specific entry point.

## Phase Sequence

| Phase | Status | Entered | Notes |
|---|---|---|---|
| bootstrap | complete | 2026-06-04T14:26:28+08:00 | Classified as feature; backlog #56 selected as closest existing roadmap item. |
| plan | complete | 2026-06-04T14:28:00+08:00 | Spec created and frozen from explicit user approval. |
| implement | complete | 2026-06-04T14:33:00+08:00 | Added review guidelines, Gemini/Copilot adapters, human guide, and guard tests. |
| review | complete | 2026-06-04T14:37:00+08:00 | AC coverage and scope checked against spec; no security findings. |
| test | complete | 2026-06-04T14:41:00+08:00 | Focused and full guard/CI tests passed. |
| handoff | complete | 2026-06-04T14:44:00+08:00 | Resume block recorded before ship. |
| ship | complete | 2026-06-04T14:45:00+08:00 | Ship metadata prepared for commit. |

## Phase Summary

- Bootstrap: Verified branch was split from `origin/main`; classified this as a feature because it introduces cross-tool contributor/review adapter behavior across multiple files.
- Plan: Targeted `AGENTS.md`, `GEMINI.md`, Copilot instruction files, `docs/ai-contributors.md`, spec/backlog metadata, and guard tests; non-goal kept generator work out of scope.
- Implement: Added concise `AGENTS.md ## Review guidelines`, Gemini and Copilot adapters, human interaction guide, and guard tests for adapter presence/length.
- Review: Verified AC-1..AC-6 by test coverage and manual diff inspection; adapter files point back to canonical governance instead of duplicating long rules.
- Test: Focused multi-agent guard tests passed; full `tests/ci` + `tests/guard` suite passed before ship metadata.
- Handoff: Work is complete and ready for ship commit; rollback is reverting the feature and ship commits.

## Known Risk

- Instruction duplication: mitigate by keeping adapters short and pointing to canonical files.
- Copilot context truncation: mitigate with a guard test that enforces `.github/copilot-instructions.md` under 4,000 characters.
- Scope creep into generator work: keep adapter generator as a non-goal.

## Resume

State: shipped
Completed: `AGENTS.md ## Review guidelines`; `GEMINI.md`; `.github/copilot-instructions.md`; `.github/instructions/governance-review.instructions.md`; `docs/ai-contributors.md`; `tests/guard/test_multi_agent_review_guidelines.py`; spec/backlog/SSoT/domain metadata.
Next: push branch, open PR, confirm CI.
Context: Implementation commit `fe0f306ef529c5b30b099b5e1b7a8bac8b561f15`; ship metadata commit pending.

### Read Map

- `docs/specs/multi-agent-review-guidelines.md` — shipped feature contract.
- `docs/ai-contributors.md` — human-facing interaction guide.
- `tests/guard/test_multi_agent_review_guidelines.py` — adapter guard tests.

### Skip List

- Do not re-read shipped historical specs unless tracing a bug.
- Do not implement a generator in this PR; backlog #56 can spawn follow-up generator work later.

### Context Snapshot

- Copilot instructions are 997 characters, below the 4,000-character code review custom-instruction limit.
- `AGENTS.md` grew from 71 to 80 lines, preserving short-entry intent.
- `CLAUDE.md` already imports `AGENTS.md`; no duplicate Claude adapter edit was needed.

### Backlog Status

- Backlog #56 moved from Pending to In Progress during bootstrap and to Shipped during ship.
