Quality

Content

92%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

A well-architected instruction skill: concrete workflow with validation checkpoints, actionable mode-selection guidance, and excellent progressive disclosure through clearly signaled reference files. Only minor redundancy across the mode-related tables keeps conciseness from a perfect score.

Dimension	Reasoning	Score
Conciseness	Lean and well-structured with no explanation of concepts Claude already knows, but mode information recurs across three tables (5 Reasoning Modes, Reference Guide, Output Templates) with overlapping Output/Deliverable columns that could be consolidated.	4 / 5
Actionability	Provides concrete executable guidance: an explicit 5-step workflow, exact AskUserQuestion two-step selection options, the specific reference file to load per mode, and a precise final output structure — fully actionable for an instruction-only skill.	5 / 5
Workflow Clarity	The Core Workflow is a clearly sequenced Identify→Select→Challenge→Engage→Synthesize flow with explicit validation checkpoints (steelman confirmation, 'ask the user to respond before proceeding') and a MUST DO / MUST NOT checklist; no destructive or batch operations apply.	5 / 5
Progressive Disclosure	SKILL.md is a concise overview pointing to six verified one-level-deep reference files via a Reference Guide table with a 'Load When' column giving clear navigation signals; no nested references.	5 / 5
	Total	19 / 20 Passed

Description

92%Weight 40%Scale 1-5

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

A strong, concrete description that clearly states what the skill does and when to use it with natural trigger phrases and a distinct niche. The only minor gap is missing a few common synonyms that users might naturally say.

Dimension	Reasoning	Score
Specificity	Lists multiple concrete actions — 'play devil's advocate, run a pre-mortem, red team, or audit evidence and assumptions' — giving comprehensive coverage of the skill's modes, matching the anchor for multiple specific concrete actions.	5 / 5
Completeness	Explicitly answers both what ('challenging ideas... using structured critical reasoning' plus four named modes) and when ('Use when challenging ideas, plans, decisions, or proposals') with concrete trigger phrases.	5 / 5
Trigger Term Quality	Includes natural phrases users say ('devil's advocate', 'pre-mortem', 'red team', 'audit evidence and assumptions') but omits common synonyms like 'stress test', 'poke holes', or 'what could go wrong' that appear only in metadata triggers.	4 / 5
Distinctiveness Conflict Risk	Occupies a clear niche (structured critical reasoning / devil's advocate) with distinct triggers (pre-mortem, red team, evidence audit) that are unlikely to fire for unrelated skills.	5 / 5
	Total	19 / 20 Passed
