From the source SKILL.md

Hold up a mirror to thinking and show the distortions. Cognitive biases are not character flaws — they're predictable patterns in how human cognition processes information under time pressure, complexity, and uncertainty. Identifying them is the first step to correcting for them.

What this skill does

Bias Detector is a community-contributed Claude Code skill in the general-misc sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/bias-detector/ and loads when your prompt matches the skill's trigger.

When to invoke it: Use when the user suspects their thinking may be biased, wants to check a decision for common reasoning errors, needs to understand why a group made an irrational choice, or wants to debias a specific judgment before acting on it.
