Conciseness

The body is mostly efficient bullets, but the stop-and-ask guidance is repeated three times ('Ask for clarification rather than guessing', "Don't force through blockers - stop and ask", 'Stop when blocked, don't guess'), 'Review plan critically first' in Remember duplicates Step 1, and the platform note about Superpowers working 'much better with access to subagents' is padded — matching 'mostly efficient but could be tightened'.

Actionability

For an instruction-only skill the guidance is concrete: verbatim announce strings, named sub-skills ('superpowers:finishing-a-development-branch', 'superpowers:using-git-worktrees'), explicit tool actions ('Create TodoWrite', 'Mark as in_progress'), and a specific stop-condition list. Minor gaps remain — 'Run verifications as specified' defers entirely to the plan without saying what to do on first failure.

Workflow Clarity

The three-step sequence is clear with real checkpoints: a concern gate before starting ('If concerns: Raise them with your human partner before starting'), per-task verification ('Run verifications as specified'), explicit stop conditions, revisit conditions, and a Remember checklist. Error recovery escalates ('Verification fails repeatedly' → stop and ask) rather than giving a fix-and-retry loop, and completion is delegated to a sub-skill, leaving minor validation gaps.

Progressive Disclosure

No bundle files exist (references/, scripts/, assets/ are absent), so everything lives appropriately in a single well-sectioned SKILL.md, with cross-skill references clearly signaled one level deep in the Integration section. The redundancy between 'When to Stop', 'When to Revisit', and 'Remember' is a minor organization gap keeping it below the top anchor.

Specificity

The description names the domain ('a written implementation plan to execute') with essentially one generic action ('execute'), listing no concrete capabilities such as running verifications or reporting. It is also phrased in the second person ('Use when you have a written implementation plan'), which per the guidelines reduces the specificity score by 1 from an anchor-3 base.

Completeness

The 'when' is explicit ('Use when you have a written implementation plan to execute in a separate session with review checkpoints'), but the 'what' is only weakly implied by the embedded phrase 'to execute' — no capability statement like 'executes each task, runs verifications, and reports results' appears. This sits between 'only when present without what' (2) and 'both present, when could be more specific' (4).

Trigger Term Quality

Relevant keywords are present ('written implementation plan', 'execute', 'separate session', 'review checkpoints') but common variations users would naturally say — 'implement the plan', 'follow the plan', 'work through the plan', 'run the plan' — are missing, matching the anchor for some relevant keywords without synonyms.

Distinctiveness Conflict Risk

The niche is clear — executing an already-written plan in a fresh session — and distinct from plan-writing or ad-hoc implementation, so it would not trigger for the wrong skill in most cases. Minor overlap risk remains with closely related workflow skills (e.g., subagent-driven development or plan-writing), matching the 'mostly distinct' anchor.
