Conciseness

The body is lean and assumes Claude's competence with no concept explanations, but the Overview line ("Load plan, review critically, execute all tasks, report when complete") restates the description and "Don't force through blockers - stop and ask" duplicates the STOP section — minor trims that fit anchor 4 rather than the every-token-earns-its-place anchor at 5.

Actionability

For an instruction-only skill the guidance is mostly executable — verbatim announce phrases, exact sub-skill gating for finishing-a-development-branch, and enumerated stop conditions — but "Read plan file" never says where the plan comes from and "identify any questions or concerns" gives no example of what a gap looks like, leaving minor gaps consistent with anchor 4.

Workflow Clarity

The three-step sequence is clearly numbered with an explicit validation checkpoint ("Run the verification the plan names for that task... and confirm it passes before moving on"), error-recovery loops (blocker stop conditions, verification-fails-repeatedly, when to return to Step 1), and a closing checklist — matching the explicit-validation anchor rather than the implicit-checkpoint anchor at 4.

Progressive Disclosure

This is a simple ~55-line skill with no bundle files and no content that belongs in separate files; sections (Process, Stop, Revisit, Remember) are well-organized and navigation is trivial, so per the rubric's simple-skill guideline it merits 5.

Specificity

The description lists four concrete actions covering the complete lifecycle — "loads the plan, reviews it critically for gaps, works through each task with its verification steps, and reports when everything is done" — which matches the comprehensive-coverage anchor rather than the minor-gaps anchor at 4.

Completeness

Both what (the enumerated action list) and when ("entered by requests like 'implement this plan'... once delivery-flow has produced a written plan") are explicitly stated with concrete trigger phrases, exactly matching the anchor-5 example pattern.

Trigger Term Quality

It quotes natural trigger phrasings users would actually say — "implement this plan", "run the plan", "execute the plan", "work through these tasks" — with synonym coverage exceeding the good-but-incomplete anchor at 4, and adds explicit negative trigger guidance.

Distinctiveness Conflict Risk

It claims a clear niche — "the execution stage inside the delivery-flow workflow" — and draws an explicit boundary ("Do not activate directly for a standalone request that has not gone through delivery-flow first"), minimizing overlap with generic implementation skills.
