GodopuandClaude Opus 5.5 65dc7fde82 release(v4.8.4): bump framework and eight skills to 4.8.4 in lockstep; archive PR #47 reviews (two rounds)
The .claude/skills check accepts both local layouts and fails on a dangling
link. Review: round 1 (@e1ed270) claude agy grok PASS, codex NOT PASS (a
dangling top-level link was skipped); fixed in 150b493; round 2 4/4 PASS.

## 2. Commit Audit (base..head)
Commit `e1ed270`: `test(issue-42): the .claude/skills check accepts both local layouts`
Diff summary:
- [`tests/test_issue42_skill_blocks.py`](file:///var/folders/q_/68sxgw3j073dgjg8wl9s08vw0000gn/T/mam-review/loop-20261004T043243Z-baf133/1/tests/test_issue42_skill_blocks.py#L238-L253):
Modified `test_claude_skills_link_resolves_to_agents_skills()` to support both local `.claude/skills` layouts:
1. A single symlink pointing directly to `.agents/skills` (`link.is_symlink()`).
2. A local directory containing individual symlinks for each skill in `SKILL_NAMES`.
**Product Code Modifications**: None (0 changes to `.sh` or `.py` product code).
---
## 3. Review Item Verification & Empirical Testing
### Item 1: Behavior Across Both Layouts & Edge Cases
Empirical tests were executed inside the verification path across all layouts and boundary cases (with temporary `.claude` structures removed after verification):
1. **Absent `.claude/skills` (Worktree default)**:
- Behavior: Skipped with `pytest.skip(".claude/skills is untracked; absent in a worktree")`.
- Result: PASS (skipped cleanly).
2. **Single Symlink Layout (`.claude/skills -> .agents/skills`)**:
- Tested: `ln -s ../.agents/skills .claude/skills`
- Behavior: `link.is_symlink()` evaluates to `True`, verifies `link.resolve() == SKILLS.resolve()`.
- Result: PASS.
3. **Per-Skill Directory Layout (Control plane / Main checkout)**:
- Tested: `.claude/skills/` containing symlinks for all 8 `multi-agent-mux-*` skills plus helper links (`lib.sh`, `lib_py`).
- Behavior: Verifies `entry.exists()` and `entry.resolve() == (SKILLS / skill).resolve()` for every skill in `SKILL_NAMES`.
- Result: PASS.
4. **Missing Skill in Directory Layout (Negative test)**:
- Tested: Omitted `multi-agent-mux-stop` symlink.
- Behavior: Fails immediately with `AssertionError: .claude/skills/multi-agent-mux-stop is missing`.
- Result: PASS (correctly caught).
5. **Misdirected Symlink Target (Negative test)**:
- Tested: Pointed `multi-agent-mux-stop` to `multi-agent-mux-create`.
- Behavior: Fails with `AssertionError: .claude/skills/multi-agent-mux-stop -> .../multi-agent-mux-create`.
- Result: PASS (correctly caught).
6. **Broken Symlink (Negative test)**:
- Tested: Pointed `multi-agent-mux-create` to nonexistent target.
- Behavior: `entry.exists()` returns `False`, failing with `AssertionError: .claude/skills/multi-agent-mux-create is missing`.
- Result: PASS (correctly caught).
7. **Regular File at `.claude/skills` (Negative test)**:
- Tested: Created plain file `.claude/skills`.
- Behavior: Child path lookup on regular file evaluates `entry.exists() == False`, failing cleanly with `AssertionError: .claude/skills/multi-agent-mux-create is missing`.
- Result: PASS (correctly caught).
8. **Static Completeness of `SKILL_NAMES`**:
- `SKILL_NAMES` is defined from `.agents/skills/multi-agent-mux-*/SKILL.md` and enforced by `test_inventory_covers_eight_skills` (`len == 8`). Cannot be empty.
### Item 2: Strictness & Flexibility Assessment
- **Appropriate Flexibility**: Allows additional local symlinks or files within `.claude/skills` (such as `lib.sh` or `lib_py`) without triggering false alarms, reflecting that Claude Code only registers subdirectories containing `SKILL.md`.
- **Appropriate Strictness**: Unconditionally requires that all 8 canonical skills are present and resolve to their exact corresponding `.agents/skills/<skill>` directories.
### Item 3: Scope & Diff Inspection
- Exactly 1 file modified: `tests/test_issue42_skill_blocks.py` (+10, -1).
- No changes to product scripts, library code, or documentation.
- No version bump.

## 4. Test Suite Execution Results
Executed in verification worktree (`/var/folders/q_/68sxgw3j073dgjg8wl9s08vw0000gn/T/mam-review/loop-20261004T043243Z-baf133/1`) with `--basetemp=/tmp/pytest-pr47`:
| Test Suite | Result | Duration |
|---|---|---|
| `tests/test_issue42_skill_blocks.py` | 31 passed, 1 skipped* | 0.07 s |
| `tests/test_version_consistency.py` | 3 passed | 0.22 s |
*\* Note: `test_claude_skills_link_resolves_to_agents_skills` skipped as expected in worktrees lacking untracked `.claude/skills`; empirical tests confirmed passing under both layouts.*
---
## 5. Conclusion
PR #47 cleanly and robustly supports both local layouts of `.claude/skills`, preventing false failures on the main checkout while maintaining strict integrity verification across all canonical skills.
[VERDICT: PASS]
