This is a well-structured planning skill with strong actionability and clear workflow sequencing. The clarification gate as a blocking step is a particularly good design choice that prevents premature plan generation. The main weaknesses are moderate verbosity in some sections (the critical details checklist and atomic task slicing contract could be tighter) and the unverifiable reference to PLAN_EXAMPLE.md which isn't included in the bundle.

Suggestions

Tighten the 'Atomic task slicing contract' section by removing redundant restatements of the one-commit-per-task principle—the concept is stated three slightly different ways.

Include the referenced `context/plans/PLAN_EXAMPLE.md` in the bundle so the progressive disclosure reference is functional and verifiable.

Dimension	Reasoning	Score
Conciseness	The skill is mostly efficient and avoids explaining concepts Claude already knows, but some sections are slightly verbose—e.g., the clarification gate's bullet list of critical details could be tightened, and the example clarification questions, while useful, add length. The atomic task slicing contract section repeats ideas (one commit, one contributor) in slightly different ways.	2 / 3
Actionability	The skill provides concrete, specific guidance throughout: exact file paths, a detailed task format template, a filled-in example task with real commands (`pnpm test`, `curl`), checkbox syntax for progress tracking, and a specific output contract with a canonical next command. This is highly actionable and copy-paste ready.	3 / 3
Workflow Clarity	The workflow is clearly sequenced: intake trigger → clarification gate (blocking) → plan writing → output contract. The clarification gate explicitly blocks progress until ambiguities are resolved, which is a strong validation checkpoint. The final task requirement for validation/cleanup and the output contract with explicit confirmation steps provide clear checkpoints throughout.	3 / 3
Progressive Disclosure	The skill references `context/plans/PLAN_EXAMPLE.md` for a full annotated reference plan, which is good progressive disclosure. However, no bundle files are provided, so this reference is unverifiable. The inline content is reasonably well-structured with clear sections, but the example task entry and the skeleton could potentially be moved to a reference file to keep the main skill leaner.	2 / 3

Description

100%

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

This is an excellent skill description that clearly communicates what the skill does (creates structured implementation plans with atomic tasks, acceptance criteria, and verification steps), where outputs go, and when to use it. The explicit 'Use when' clause covers multiple natural trigger scenarios, and the specificity of the SCE format and output path make it highly distinctive.

Dimension	Reasoning	Score
Specificity	Lists multiple specific concrete actions: creates/updates structured plans, breaks change requests into scoped atomic tasks, specifies clear goals, boundaries, acceptance criteria, and verification steps. Also specifies the output path format.	3 / 3
Completeness	Clearly answers both 'what' (creates structured implementation plans with atomic tasks, goals, boundaries, acceptance criteria, verification steps) and 'when' (explicit 'Use when' clause covering feature planning, refactoring, integration, task breakdowns, and roadmaps).	3 / 3
Trigger Term Quality	Includes strong natural trigger terms users would say: 'plan a new feature', 'refactor', 'integration', 'project plan', 'task breakdown', 'implementation roadmap', 'work plan', 'change request', 'success criteria', 'structured planning'. Good coverage of variations.	3 / 3
Distinctiveness Conflict Risk	Highly distinctive with the specific SCE plan format, output path (`context/plans/{plan_name}.md`), and focus on pre-execution structured planning. The combination of implementation planning with specific file output and atomic task decomposition creates a clear niche unlikely to conflict with other skills.	3 / 3
