chore: sync codex + gemini indices after code-reviewer C# update

[alirezarezvani]

Summary

Post-merge follow-up to #730. Phase 7 of the plugin audit on engineering-team/skills/code-reviewer found the cross-platform skill indices were stale — still showing the pre-#723 description without "C#, and .NET". This commits the auto-fix from scripts/sync-codex-skills.py + scripts/sync-gemini-skills.py.

Re-running the syncers also picked up two unrelated drifted entries (.codex/skills/{review,run,status} symlinks, .gemini/skills/claude-coach/ symlink) — included in the same commit since they're all canonical-sync output.

Audit verdict for code-reviewer (PR #730 changes)

Phase	Result
1 — Discovery	Single-skill, engineering-team, 3 scripts, 3 references
2 — Structure	PASS 86.4/100 GOOD
3 — Quality	WARN 54.8/100 D (pre-existing baseline — missing README/assets/expected_outputs; not regressions)
4 — Scripts	PASS 3/3
5 — Security	PASS 0 critical, 0 high (9 files scanned)
6 — Marketplace	PASS (bundled under parent engineering-team v2.8.1, plugin.json valid)
7 — Ecosystem	PASS WITH AUTO-FIX (this PR)
8 — Code review	PASS (cs-senior-engineer criteria)

Type of Change

• Infrastructure / CI (index sync)

Draft for review.

Code Review — PR #734: codex + gemini index sync

Overall this is a clean, well-scoped infrastructure PR. The audit verdict table in the description is a nice touch. A few observations:

---

What's correct

• Gemini code-reviewer description (C#, and .NET) — matches the codex entry and the actual skill after PR feat(code-reviewer): deliver C# / .NET implementation behind PR #723 docs #730. Verified.
• claude-coach addition to gemini — it was already in .codex/skills-index.json and .codex/skills/; gemini was the only index missing it. Source path (../../../engineering/claude-coach/skills/claude-coach/SKILL.md) resolves to a real directory. ✅
• Count arithmetic — total_skills 393 → 394 (+1 for claude-coach) and engineering-advanced 77 → 78 are both correct. ✅
• Symlink targets — all three repointed codex symlinks (review, run, status) point to paths that exist on disk. ✅
• Hermes — .hermes/skills/ uses a single claude-skills bundle, not per-skill symlinks, so no update needed there. ✅

Issues worth addressing before merge

1. Non-deterministic symlink collision resolution (existing design flaw, surfaced here)

Three slug names — review, run, status — each have two source skills:

Slug	Option A	Option B
review	engineering-team/playwright-pro/skills/review	engineering-team/self-improving-agent/skills/review
run	engineering/agenthub/skills/run	engineering/autoresearch-agent/skills/run
status	engineering/agenthub/skills/status	engineering/autoresearch-agent/skills/status

sync-codex-skills.py sorts by (category, name) then creates symlinks in iteration order — the last entry processed for a given name wins. Path.iterdir() order on Linux is inode/readdir order, which is not alphabetical and can differ between machines, kernels, or after a filesystem operation. This means re-running the syncer on a clean clone could flip these symlinks again and produce another drift-fix PR.

Suggested fix in create_symlinks(): add an explicit tie-breaking rule, e.g. alphabetical by source path, so the winner is deterministic:

# When multiple skills share a name, last-write wins — sort source ascending
# so the alphabetically-later source (more specific plugin) always wins.
for skill in sorted(skills, key=lambda s: (s["category"], s["name"], s["source"])):

Or keep an explicit priority list. Either way, document the rule in the script.

2. Both colliding entries remain in the JSON index

The skills-index.json keeps both review entries (and both run, both status). This means:

• Tooling doing a name lookup gets two hits and must pick one.
• The index does not reflect which path the actual symlink points to.

The PR only reorders the duplicate pairs — the underlying ambiguity isn't resolved. Consider either: (a) deduplicating in the index, keeping only the "winner", or (b) adding a "collision": true marker so tooling can handle it explicitly.

3. Minor: PR description overstates what was stale in codex

still showing the pre-#723 description without "C#, and .NET"

The .codex/skills-index.json already had the correct description before this PR (verified: "description": "Code review automation for TypeScript, JavaScript, Python, Go, Swift, Kotlin, C#, and .NET…"). Only the gemini index needed updating. The codex diff in this PR is purely the symlink reordering, not a description fix. This is actually fine — it just means the PR description is slightly inaccurate about the scope.

---

Summary

The actual file changes are correct. The main blocker before moving out of DRAFT is the symlink non-determinism — without a stable tie-breaking rule, this exact fix could regress the next time someone runs the syncer on a fresh machine. The duplicate-index entries are a pre-existing issue; at minimum, linking it to a follow-up issue would prevent the next reviewer from spending time on it.
