Conciseness

The body is dense and efficient — tables, phase lists, exact prompts, and specific tool names with almost no explanation of concepts Claude already knows. However, the "Workflow" section (lines 240-245) and much of the "Examples" section recap rules already stated in "Mode Detection", "CI vs Interactive", and the phase descriptions, so it could be tightened; this fits "efficient; minor instances of over-explanation that could be trimmed" rather than the 3 anchor's "some unnecessary explanation".

Actionability

Guidance is fully executable for an instruction-only skill: exact file paths (`.qa/config.yml`, `.qa/reports/YYYY-MM-DD-HHmmss-qa-report.md`), exact MCP tool names (`mcp__github__get_pull_request`, `mcp__linear__get_issue`), copy-ready prompt templates for every user interaction, concrete agent-selection conditions, and a prioritized spawn strategy. This matches the 5 anchor's "copy-paste ready... specific examples cover the common cases"; the 4 anchor would imply missing key details.

Workflow Clarity

Mode A's six phases are explicitly sequenced ("Follow these phases IN SEQUENCE") with validation checkpoints and feedback loops: stop if the test plan is empty, warn on missing env vars, detect STOPPED_EARLY blockers, and after bug fixes "re-run ONLY failing scenarios to verify" with an explicit "If still broken: ask user for another iteration" recovery path. This matches the 5 anchor's "explicit validation steps; feedback loops for error recovery"; the 4 anchor would require missing checkpoints.

Progressive Disclosure

Structure is good — the body stays an overview, templates are clearly signaled one level deep in `references/` (config.md, test-plan.md, env-qa.md all exist) — but three files referenced as load-bearing (`rules/orch-spawn.md` marked CRITICAL, `rules/orch-triage.md`, `rules/orch-report.md` which defines the report format used in Phase 6) do not exist anywhere in the bundle, so the report format is never actually defined. This falls between the 3 anchor (structure present but organization issues) and the 4 anchor ("minor organization gaps") — missing referenced files are more than a minor gap, so 3.

Specificity

The description lists multiple specific concrete actions covering the full pipeline: "spawn test agents in parallel, collect results, triage bugs, trigger the bug fixer, and generate QA reports". This matches the comprehensive-coverage anchor; it is not the level below (4), which would require minor gaps in the action list.

Completeness

It explicitly answers both questions: what it does ("spawn test agents in parallel, collect results, triage bugs, trigger the bug fixer, and generate QA reports") and when to use it ("Trigger on 'run QA', 'start QA session', 'test the PR'..."). This matches the 5 anchor with concrete trigger phrases; the 4 anchor would require the 'when' to be less explicit.

Trigger Term Quality

Natural trigger phrases users would actually say are comprehensively covered: "run QA", "start QA session", "test the PR", "orchestrate QA agents", "run multiple QA agents together", plus the explicit "/qa-orchestrator" command name as a synonym. Nothing users commonly say for this need is missing, so it fits the comprehensive anchor rather than the 4 anchor ("a few natural terms missing").

Distinctiveness Conflict Risk

It occupies a clear niche (QA agent orchestration as "the main entry point for running a QA session") with distinct trigger phrases that would not naturally invoke a generic testing or bug-fixing skill. The QA-session framing keeps conflict risk minimal, fitting the 5 rather than the 4 anchor ("minor overlap risk with closely related skills").
