Conciseness

The body is directive and assumes competence ("DRY. YAGNI. TDD. Frequent commits.", "Assume they are a skilled developer") with no padding explaining known concepts, but the Task Right-Sizing and Bite-Sized Task Granularity sections overlap and a few rationale sentences ("You reason best about code you can hold in context at once") could be trimmed, matching the efficient-with-minor-trimmables anchor.

Actionability

Full copy-paste-ready templates give exact file paths (`Create: exact/path/to/file.py`), runnable commands (`pytest tests/path/test.py::test_name -v`, `git commit -m "feat: ..."`), expected outcomes ("Expected: FAIL with 'function not defined'"), and an explicit ban on placeholders — fully executable guidance covering the common cases.

Workflow Clarity

The process is clearly sequenced (announce → scope check → file structure → task sizing → header → tasks → self-review → handoff) with explicit validation checkpoints baked into every task template (run the test to verify it fails, then verify it passes) and a fix-and-continue feedback loop in Self-Review ("If you find issues, fix them inline... If you find a spec requirement with no task, add the task").

Progressive Disclosure

The skill is a single self-contained file with clear section headers and no nested references (no references/, scripts/, or assets/ bundles exist), but the two substantial markdown templates are inlined and there are no external reference files at all, leaving minor organization/split opportunities — matching the good-structure-with-minor-gaps anchor rather than the clear overview with well-signaled references.

Specificity

"breaking the work into bite-sized, testable tasks with exact file paths, code samples, and test commands an engineer can follow step by step" lists multiple concrete actions with concrete deliverable artifacts, matching the comprehensive-coverage anchor rather than the minor-gaps anchor below it.

Completeness

The "what" is explicit and concrete, and the "when" is present ("run after delivery-flow splits the work into multiple meaningful implementation units"), but the trigger guidance is workflow-positional and negative ("do not activate it directly") rather than concrete positive trigger phrases, so it does not reach the anchor 5 example.

Trigger Term Quality

"implementation plan", "feature, spec, or ticket" are natural terms users would say, but common variations such as "design doc", "planning", or "break down this work" are missing, so coverage is good but not comprehensive.

Distinctiveness Conflict Risk

"It is not a standalone entry point, so do not activate it directly for a one-off user request or a narrow change; use delivery-flow for those instead" carves out a clear niche and explicitly disambiguates against the nearest conflicting skill, giving minimal conflict risk.
