022-root-cause-analysis

Use when a framed problem needs root-cause investigation rather than a symptom-level fix, applying Five Whys, Fishbone (Ishikawa), Current Reality Tree, and constraint identification. This should trigger when an issue's Root Cause Analysis point of view needs evaluation, or when a maintainer directly asks to find the root cause of a problem before proposing a fix.

Quality

Content

86%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-structured, concise instruction-only skill body with a clear workflow and a clean one-level-deep reference that exists. Actionability and workflow_clarity are strong but stop just short of fully executable checkpoints/output templates.

Dimension	Reasoning	Score
Conciseness	Lean and efficient with no padding or over-explanation of concepts Claude already knows; every section (Constraints, When to use, Workflow) earns its place.	5 / 5
Actionability	Provides concrete, specific guidance (chain why questions 'stopping when further why steps would require guessing', named Fishbone categories), but as an instruction-only skill it lacks a concrete inline output template.	4 / 5
Workflow Clarity	A clear 6-step sequence with embedded guidance to flag open findings, but checkpoints are implicit rather than explicit validate-then-fix-then-retry loops.	4 / 5
Progressive Disclosure	The body is a concise overview pointing to a single one-level-deep, clearly-signaled reference (references/022-root-cause-analysis.md), which exists and holds the detailed guidance; navigation is easy.	5 / 5

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, specific description that names concrete techniques and provides explicit 'Use when' trigger guidance with natural phrasing. Slightly formal trigger language keeps trigger_term_quality just short of comprehensive.

Dimension	Reasoning	Score
Specificity	Names the domain and lists multiple concrete techniques — 'Five Whys, Fishbone (Ishikawa), Current Reality Tree, and constraint identification' — providing comprehensive coverage of specific actions.	5 / 5
Completeness	Explicitly answers both 'what' (the four named techniques) and 'when' via the 'Use when a framed problem needs root-cause investigation' clause plus concrete trigger conditions.	5 / 5
Trigger Term Quality	Includes natural trigger phrases users would say ('find the root cause of a problem', 'Root Cause Analysis', 'maintainer directly asks'), but a few common synonyms or phrasings are missing.	4 / 5
Distinctiveness Conflict Risk	Occupies a clear RCA niche with distinct technique-specific triggers and minimal overlap risk with unrelated skills.	5 / 5
