# Bias Check Skill Pre-research and pre-decision bias review. ## Workflow 1. **Identify context**: What stage (L0-L5)? What activity (research, decision, evaluation)? 2. **Load stage-specific checklist** from cognitive-biases.md for the current scale. 3. **For each bias on the checklist**: - Is this bias likely active in the current situation? (Yes/No/Maybe) - If Yes/Maybe: What specific mitigation will be applied? - Document the assessment. 4. **Check agent's own biases** (from cognitive-biases.md agent section): - Sycophancy: Am I agreeing with the user when evidence says otherwise? - Recency: Am I overweighting recent context over earlier evidence? - Pattern matching: Am I assuming this is like something I've seen before without checking? - Completionism: Am I filling gaps with speculation rather than acknowledging uncertainty? 5. **Output bias briefing**: ``` ## Bias Check: [Activity] Stage: [L0-L5] ### Active Risks | Bias | Risk Level | Mitigation | |------|-----------|------------| | ... | High/Med/Low | ... | ### Agent Self-Check - Sycophancy: [OK/Risk] - Recency: [OK/Risk] - Pattern matching: [OK/Risk] - Completionism: [OK/Risk] ### Proceed?

Where does this skill come from?
From majiayu000/claude-skill-registry, a repository with 534 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
