## Purpose
Detect biased reasoning, oversimplification, hidden assumptions, and weak logic.

## Use when
- the analysis feels too neat
- a preferred solution may be biasing the work
- critical review is required before decisions

## Inputs
- artifact or analysis output under review
- source material and assumptions
- project context and quality bar

## Procedure
1. Inspect the artifact systematically.
2. Look for omissions, contradictions, weak assumptions, and vague language.
3. Distinguish evidence-backed claims from inference.
4. Record issues by severity.
5. Recommend targeted fixes, not generic criticism.
6. Re-state what would make the artifact review-ready.

## Outputs
- bias and assumption log
- rival interpretations
- logic weaknesses
- revised decision notes

## Guardrails
- Be concrete.
- Do not rewrite the whole artifact unless necessary.
- Focus on the highest-leverage defects first.
- Prefer explainable quality gates.

## Completion criteria
- key defects identified
- fixes proposed
- pass/fail or ready/not-ready decision given
