Conciseness

At ~373 lines the skill is noticeably verbose: the 大企業詰め拡張パック (~107 lines of company-flavored motivational speeches) and repeated hammering of the verification/proactivity point heavily pad the context. It is above anchor 1 because genuine methodological content is embedded, but several sections are unnecessary padding, matching anchor 2.

Actionability

Concrete executable directives appear throughout (buildしろ、curlで戻り値を確認しろ、前後50行を確認、完全なエラーメッセージを検索、公式ドキュメント+Issuesを検索) plus concrete checklists and a failure-pattern→flavor selector table. For an instruction-only skill this is mostly actionable guidance with minor gaps from the motivational prose, matching anchor 4.

Workflow Clarity

The 5-step methodology and L1-L4 escalation are clearly sequenced with explicit validation steps, feedback loops (Step 5 振り返り → 鉄則三 follow-up), and checklists (7-item, proactivity). It is not a 5 because the proliferation of parallel overlapping frameworks creates minor ambiguity about which workflow applies when.

Progressive Disclosure

The skill has clear section structure (headers, tables) but is monolithic at 373 lines with no bundle files and no external references, while large chunks (the flavor pack, Agent Team integration) clearly belong in separate reference files. This matches anchor 3 (some structure, content that should be separate is inline); it is above anchor 2 because the structure is not minimal.

Specificity

Names the domain (生産性コーチングモード) and two concrete actions (構造化トラブルシューティング, 証拠ベースの完了確認), but coverage is not comprehensive. This matches anchor 3 (domain + 1-2 concrete actions); it lacks the multiple specific actions needed for a 4.

Completeness

Explicitly answers both 'what' (構造化トラブルシューティングと証拠ベースの完了確認を促す) and 'when' (明示的な依頼、反復失敗、受け身、検証不足、品質不満のときに) with concrete trigger phrases. The explicit 'Use when' equivalent (...のときに) with concrete triggers matches anchor 5; it is not capped at 3 because trigger guidance is present.

Trigger Term Quality

Trigger conditions (明示的な依頼、反復失敗、受け身、検証不足、品質不満) cover several scenarios but are mostly internal behavioral states the model observes rather than natural phrases a user would say, missing common variations/synonyms. Anchor 3 (some relevant keywords, missing variations) is the best fit; not a 4 because the terms are not natural user utterances.

Distinctiveness Conflict Risk

The productivity-coaching niche with specific behavioral triggers is mostly distinct, with only minor overlap risk against debugging or methodology skills. It is not a 5 because the coaching/verification theme does share conceptual space with general systematic-debugging skills.
