Conciseness

Lean ~74-line body with no over-explanation of concepts Claude already knows; every section (Orient, Invent, Judge, File, Boundaries) earns its place and assumes Claude's competence.

Actionability

Provides concrete executable commands ('gh issue create --title ... --label idea', 'gh label create <name> --force', 'gh issue lock <number>'); placeholders in the body template keep it just short of copy-paste-ready.

Workflow Clarity

Clear orient→invent→judge→file sequence with explicit validation checkpoints — the 'ALL must hold' value-bar checklist, queue back-pressure ('if 5 or more... file nothing'), dedup, max-3 cap, and 'if nothing passes, file nothing' feedback gate.

Progressive Disclosure

Single well-organized file with clearly signaled one-level references to repo artifacts (IMPLEMENTATION_PLAN.md, docs/progress-log.md, docs/task-automation.md); no skill-bundle files to split, and at 74 lines the inline structure is appropriate but not a textbook multi-file overview.

Specificity

Lists several concrete actions ('invent improvements', 'judge them against the value bar', 'file the winners as locked `idea` issues') and an explicit non-action ('Never implements anything'); the 'autonomous value-creation loop' framing is slightly abstract, keeping it just below comprehensive.

Completeness

Explicitly answers what ('invent...judge...file the winners as locked idea issues') and when ('Use when the user says...') with concrete trigger phrases, matching the top anchor.

Trigger Term Quality

Includes natural user phrases ('アイデア出して', 'next idea', 'wants proposals without implementation') that a user would actually say, but coverage of synonyms is not exhaustive.

Distinctiveness Conflict Risk

Clear niche — ideation only, explicitly distinguished from the next-task skill ('the next-task skill builds from the queue this skill fills') with distinct triggers and minimal overlap risk.
