Conciseness

The body is lean and command-driven — worktree creation, build limits, spawn commands, a 3-minute monitoring cadence, and a tight Key Rules section — with no explanation of concepts Claude already knows; only the brief supervisor-role restatement of the description keeps it from being pure anchor 5, and that line still orients the agent usefully, so anchor 5 ('lean and efficient; every token earns its place') is the best fit over anchor 4.

Actionability

Most guidance is copy-paste executable ('git worktree add ../$(basename $PWD)-issue-<NUMBER> -b fix/issue-<NUMBER>', 'pnpx tsx <path-to-mastracode>/src/main.ts --timeout 1800', 'gh pr checks <PR_NUMBER>'), but the unresolved '<path-to-mastracode>' placeholder and reliance on the undocumented '/gh-new-pr conventions' are minor gaps, fitting anchor 4 ('mostly executable; minor gaps') rather than anchor 5's fully copy-paste-ready bar.

Workflow Clarity

The sequence is explicit (inputs → worktree setup → parallel spawn → 3-minute monitoring → timeout/restart → PR creation → comment handling → CI checks) with validation checkpoints ('Check git diff --stat', 'Review all mc output before creating PRs — subagent work is untrusted'), feedback loops for every failure mode (timeout restart with continuation context, CI fix instances, PR comment instances), and a Key Rules checklist — anchor 5. This batch operation includes validation, so the workflow cap does not apply.

Progressive Disclosure

No bundle files exist and none are needed for this orchestration skill; the body is well-sectioned and self-contained. It falls just short of anchor 5 because it leans on external skill references ('/gh-new-pr conventions', '/gh-pr-comments', '/gh-fix-ci') whose conventions are not available in the bundle — a minor organization gap matching anchor 4 ('good structure; minor organization gaps').

Specificity

The description names its domain and several concrete actions — 'Orchestrate parallel Mastra Code headless instances to debug and fix multiple GitHub issues simultaneously' — but omits parts of the actual scope (monitoring, PR creation, CI fixes), matching anchor 4 ('several specific actions; minor gaps') rather than anchor 5's comprehensive coverage; it is clearly above anchor 3's '1-2 concrete actions'.

Completeness

The 'what' is clear (orchestrate parallel headless instances to debug and fix multiple GitHub issues), but there is no 'Use when...' clause or equivalent explicit trigger guidance, which per the judging guidelines caps completeness at 3 ('clear what but when is missing or only weakly implied').

Trigger Term Quality

Relevant keywords exist ('GitHub issues', 'debug', 'fix', 'parallel', 'Mastra Code') but common natural variations a user would say are missing ('many issues at once', 'batch', 'bulk'), matching anchor 3 ('some relevant keywords but missing common variations or synonyms') — below anchor 4's good coverage and above anchor 2's one-or-two generic terms.

Distinctiveness Conflict Risk

The niche pairing of 'Mastra Code headless instances' with 'multiple GitHub issues simultaneously' is distinctive, matching anchor 4 ('mostly distinct; minor overlap risk') — it could still collide with a generic single-issue-fixing skill, so not anchor 5, but it is far more specific than anchor 3's 'works with document files' level of overlap.
