Conciseness

The body is imperative and lean with no explanation of concepts Claude already knows ('Run npx ai-devkit@latest lint --feature <name>', 'record completed/blocked/new tasks, blockers, and next action per task'). It is not 5 because the lint command and the 'If task tracing is available' clause repeat across the Phase Contract and both procedures and could be consolidated, and not 3 because there is no unnecessary explanation or padding.

Actionability

Concrete executable commands ('npx ai-devkit@latest lint --feature <name>', resolve '.ai-devkit.json paths.docs, falling back to docs/ai') and specific per-task fields (outcome, dependencies, validation evidence, related testing scenarios) give mostly executable guidance. It is not 5 because there is no copy-paste-ready example of a task entry or planning-doc format, and not 3 because the guidance is concrete and specific rather than high-level hints.

Workflow Clarity

Both procedures are clearly sequenced numbered lists with explicit phase transitions ('Next: dev-implementation'; 'if all done, run implementation verification before testing and review') and a validation checkpoint ('Verify every test-plan scenario has at least one implementation task'). It is not 5 because reconciliation has no explicit verify-after-write or error-recovery feedback loop, and not 3 because checkpoints are present, not merely implied.

Progressive Disclosure

The body is a 44-line, self-contained instruction skill with no bundle files, and its well-organized sections (Phase Contract, Create Initial Plan, Update Planning) with clear next-phase navigation match the under-50-lines simple-skill exception. It is not 4 because there is no content that clearly belongs in a separate reference file and navigation between the two procedures is unambiguous.

Specificity

Names the domain ('feature task plans') with two concrete actions ('creating and reconciling'), matching the anchor for 1-2 concrete actions without comprehensive coverage. It is not 4 because it does not enumerate several specific actions, and not 2 because the actions named are more than minimal or generic.

Completeness

Both what ('creating and reconciling feature task plans') and when (explicit 'Use when the user wants to create an implementation plan, update planning docs, mark task progress, capture blockers or new tasks...') are present, with the when clause concrete and multi-trigger. It is not 5 because the what-side ('Planning phase guidance for...') is thinner and less concretely enumerated than the 5 anchor's action list, and not 3 because the when is explicit, not implied.

Trigger Term Quality

'implementation plan', 'update planning docs', 'mark task progress', 'capture blockers', and 'new tasks' are natural phrases users would say, giving good keyword coverage. It is not 5 because kit-specific jargon ('AI DevKit', 'dev-lifecycle') stands in for common synonyms a user might use, and not 3 because the natural terms present go beyond 'some relevant keywords'.

Distinctiveness Conflict Risk

Scoping to 'AI DevKit' and 'dev-lifecycle planning work' carves a mostly distinct niche with clear triggers, though 'create an implementation plan' could overlap with general planning skills. It is not 5 because generic planning phrasing keeps some overlap risk, and not 3 because the kit-specific framing makes wrong-skill triggering unlikely.
