What to build

2 of 3 marketplace skills the producer gated with skill-quality:check fail the marketplace's own static gate — evidence the gate is not run in this repo's CI. Producer results: planning:interview FAIL (MD041 first-line H2; MD013 ×8 clustered in the dynamic ## Pre-computed context injection block; MD060 table pipe; 264-line hub; no "Use when:" phrasing warning), source-control:setup FAIL (already fixed via #1140/PR #1146), re-anchor:sweep-all-disciplines PASS clean.

NOTE before "fixing" lint: this repo's .markdownlint-cli2.jsonc disables MD013 and MD041 repo-side — the producer ran the gate from a consumer context without that config. First verify which findings actually apply under the repo's own lint config (the #1140 lesson), and whether the gate applies repo lint config when run in CI.

Ship:

1. Run skill-quality:check in this repo's CI over changed skills (changed-file-scoped, not full-tree, to keep CI fast) so shipped skills cannot regress below the marketplace's own bar.
2. Decide deliberately whether dynamic-injection blocks (declared shell: blocks) are lint-exempt, and encode that decision in the gate itself instead of leaving them as permanent per-consumer failures. Record the decision.
3. Fix whatever planning:interview findings remain valid under the repo's lint config + the injection-block decision (e.g. MD060 table pipe, hub length soft-cap consideration, "Use when:" phrasing).

Acceptance criteria

• CI job runs the skill-quality gate over skills changed in the PR; red on gate errors
• Injection-block lint-exemption decision made, encoded in the gate (skill-quality plugin), and documented
• planning:interview passes the gate under the repo's lint config after the decision is applied
• No "fixes" applied for rules the repo's .markdownlint-cli2.jsonc disables
• Version bumps for every touched plugin per semver weight

Blocked by

None — can start immediately (serialize after the skill-quality resolution fix to avoid same-file conflicts).
