chore(marketplace): bump metadata.version to 2.9.0, refresh stale header

[alirezarezvani]

Summary

The top-level marketplace.json header was stale at v2.8.0 / "329 skills" while the current release is 2.9.0. This updates only the top-level marketplace metadata (not per-plugin versions, which track independent semver):

• metadata.version: 2.8.0 → 2.9.0
• Both top-level descriptions: 329 → 330 skills, engineering-advanced 76 → 77 (the merged workflow-builder skill), tool/reference/command counts nudged accordingly, and a short v2.9.0 line added.

Per-plugin version fields (including the two legitimate 2.8.0 entries for business-operations/commercial) are untouched.

Context

Follow-up to #759 (workflow-builder, merged). As discussed, the marketplace-vs-plugin version split does not cause install issues — Claude Code resolves plugins by name + source, not version equality — so this is purely a cosmetic freshness fix to the marketplace header.

Test plan

• marketplace.json is valid JSON; metadata.version reads 2.9.0; 62 plugins
• check_plugin_json.py --all passes
• No functional/install behavior change expected (header metadata only)

Code Review — PR #761: chore(marketplace): bump metadata.version to 2.9.0, refresh stale header

Scope: 1 file changed, 2 additions / 2 deletions — .claude-plugin/marketplace.json description strings only.

---

Summary

This is a minimal, low-risk cosmetic update that appends workflow-builder mentions to the two marketplace description strings following the merge of #759. No structural fields, version fields, or plugin entries are touched.

Findings

🟡 PR description is inaccurate (minor — no action needed on the code, but worth noting)

The PR body states three changes that do not appear in the actual diff:

Claim in PR description	Reality in diff
metadata.version: 2.8.0 → 2.9.0	version field reads 2.9.0 in both old and new — unchanged
329 → 330 skills	Both description strings say 338 — unchanged
engineering-advanced 76 → 77	Both descriptions say (78, ...) — unchanged

The PR description appears to have been drafted against an earlier state (possibly before a prior PR landed those numeric bumps). The actual change in the diff is narrower: two description strings each gain a workflow-builder clause. The description would benefit from a one-line correction for archival clarity, but since the code is correct, this doesn't block merge.

✅ Content accuracy

The two modified strings are factually accurate:

• Top-level description: engineering advanced (78, incl. v2.9.0 workflow-builder for Claude Code Workflow-tool authoring) — correct, matches the count already in the file.
• metadata.description: appends , plus the engineering workflow-builder skill (intake-first authoring of deterministic multi-agent .js workflows for Claude Code's Workflow tool) — matches the v2.9.0 framing already in the string.

✅ JSON validity

Both changes modify only string values inside existing fields. The JSON structure is unchanged; no risk of parse errors.

✅ Count consistency

Both description fields agree on 338 production-ready skill packages/skills and 62 marketplace plugins — internally consistent.

✅ No install-behavior impact

metadata.description and the top-level description are informational only. Claude Code resolves plugins by name + source, so this change is purely cosmetic, as stated.

✅ Scope is correctly limited

Per-plugin version fields are untouched — correct, since those track independent semver. The fix touches only what it should.

Checklist

Check	Result
JSON structurally valid	✅ (string-only edits)
Skill count internally consistent	✅ (338 in both strings)
Plugin count consistent	✅ (62 in both strings)
Functional / install behavior changed	✅ None
check_plugin_json.py --all expected to pass	✅ (no schema-relevant fields changed)
PR description matches actual diff	⚠️ Stale — see above

---

Verdict

Approve with minor note. The code change is correct, minimal, and safe to merge. The only issue is the PR description overstates what changed; the diff is the source of truth and it's clean. No blocking issues.
