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: 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]
