Conciseness

The body is lean and procedural with no concept explanations or padding — e.g. 'Run `npx ai-devkit@latest lint` before phase work' and 'Convert goals, user stories, design components... into implementation tasks' — assuming Claude's competence so every token earns its place.

Actionability

Provides concrete, executable commands throughout (`npx ai-devkit@latest lint`, `npx ai-devkit@latest lint --feature <name>`, resolving `.ai-devkit.json` paths.docs) with specific step-by-step guidance; absence of full code blocks is appropriate for this instruction-only skill.

Workflow Clarity

Clear sequenced workflows for both Create Initial Plan (1–9) and Update Planning (1–8) with an explicit validation gate ('Run lint before phase work') and a verify step ('Verify every test-plan scenario has at least one implementation task'), plus explicit phase transitions ('Next: dev-implementation').

Progressive Disclosure

No bundle files are present or needed; the ~43-line body is self-contained and organized into clear sections (Phase Contract, Create Initial Plan, Update Planning), which satisfies the score-3 simple-skill allowance for under-50-line skills with no external references.

Specificity

Lists multiple concrete actions such as 'creating and reconciling feature task plans', 'create an implementation plan, update planning docs, mark task progress, capture blockers or new tasks', matching the score-3 anchor of multiple specific concrete actions.

Completeness

Explicitly answers both what ('Planning phase guidance for creating and reconciling feature task plans') and when ('Use when the user wants to create an implementation plan, update planning docs, mark task progress, capture blockers or new tasks...'), satisfying the score-3 anchor with explicit triggers.

Trigger Term Quality

Includes some natural phrases a user would say ('create an implementation plan', 'update planning docs', 'capture blockers'), but leans on internal jargon like 'dev-lifecycle' and lacks the breadth of common natural variations seen in the score-3 anchor.

Distinctiveness Conflict Risk

Scoped to the AI DevKit planning phase with planning-specific triggers (create/update plans, capture blockers), giving it a clear niche unlikely to trigger for sibling dev-lifecycle skills.
