The body is mostly efficient procedural guidance, but it pads with repeated 'CRITICAL' test mandates restated across the Development Approach, Testing Strategy, and Implementation Steps sections, which could be tightened.

It provides concrete executable guidance throughout: exact file paths, a full plan template with checkboxes, specific AskUserQuestion JSON, and a dependency-detection table mapping starters to skills.

Steps 0 through 3 are clearly sequenced with explicit validation checkpoints (tests must pass before next task, STOP before moving on, re-ask loop after IDE review) and error-recovery feedback loops.

No bundle files are present and the skill is a single self-contained SKILL.md, but the plan template and task guidelines are embedded inline as a large block that could be split into a referenced template file.

The phrase 'Create structured implementation plan' names the core action and a concrete artifact ('docs/plans/'), but it lists a single action rather than multiple specific concrete actions, falling short of the score-3 anchor.

It states what the skill does (create a plan in docs/plans/) but includes no 'Use when...' clause or equivalent explicit trigger guidance, capping completeness at 2 per the rubric.

It includes the relevant keyword 'implementation plan', which a user might say, but it lacks common variations like 'plan a feature', 'feature plan', or 'task plan', so coverage is partial.

'Create structured implementation plan in docs/plans/' is somewhat specific to a niche but 'implementation plan' is generic enough to overlap with other planning skills, not a fully distinct trigger set.
