Conciseness

The body is mostly concrete templates and tables rather than explanation of known concepts, but there are padded sections: the ~80-line "Example: Complete Task" largely restates the Task Template, the "MANDATORY COMPLIANCE" block repeats its prohibition three ways, and the "Decisions before tasks" section (tracker claiming, "Beads is not an end-user requirement") drifts off-topic. Not a 2 because the bulk is directly actionable material, and not a 4 because the duplicate example and compliance padding are clearly trimmable.

Actionability

Guidance is fully executable and copy-paste ready: exact file paths ("Create: `src/validators/email.ts`"), complete TypeScript test and implementation code, exact commands ("npm test tests/validators/email.spec.ts") with expected output strings, and commit commands with messages. The worked example covers the common case end-to-end.

Workflow Clarity

The task template lays out an explicit TDD sequence with validation checkpoints (write failing test → verify it fails → implement → verify it passes → commit), and checklists reinforce it. Not a 5 because the top-level plan-creation workflow is organizational rather than sequenced, and error-recovery guidance exists implicitly via expected outputs but is not spelled out as a feedback loop.

Progressive Disclosure

Sections are well-organized with clear headers, but the body is ~340 lines of monolithic content — the full worked example and the long task template are strong candidates for separate reference files. The two file references ("skills/blocks/engineering-method-selection.md", "skills/blocks/codex-host-adapter.md") point to plugin-internal paths, and this bundle has no references/, scripts/, or assets/ directories, so navigation to detail files is not clearly signaled within the skill.

Specificity

The description names one core action — "Create zero-context implementation plans" — with the attributes "zero-context" and "bite-sized tasks", which is domain-plus-1-2-concrete-actions coverage rather than the multiple specific actions of a 4 or 5. It does not list what a plan contains (file paths, test steps, commits), so it is not comprehensive.

Completeness

Both parts are present: the what is "Create zero-context implementation plans with bite-sized tasks" and the when is the explicit "use for multi-step feature planning". It is not a 5 because the when is a single terse clause — it lacks concrete trigger phrases like "when the user asks to plan a feature or break work into tasks".

Trigger Term Quality

"implementation plans" and "multi-step feature planning" are relevant phrases a user might say, but common variations are missing: "write a plan", "break down work", "task breakdown", "plan a feature". Coverage is partial rather than good (4) since several natural trigger phrasings users would actually use are absent.

Distinctiveness Conflict Risk

The zero-context/bite-sized-task planning niche is fairly distinct from execution or review skills, with "implementation plans" as a clear discriminator. Minor overlap remains with general project-planning, roadmap, or decomposition skills, so it does not reach the clear-niche level of 5.
