Adversarial code review with three parallel perspectives — Advocate, Skeptic, Architect — that create productive tension. Use for high-stakes PRs, architectural changes, or when single-pass review would miss issues. Surfaces findings through disagreement, not consensus.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Deep Review
Perform thorough code review using three perspectives with opposing mindsets. Their disagreement surfaces issues; their agreement signals confidence.
## When to Use
- Architectural changes, multi-file refactors, or security-sensitive code
- PRs that are too important for single-pass review
- When you suspect confirmation bias in a standard review
- High-stakes merges where the cost of a missed issue is high
## When NOT to Use
- Routine single-file edits (use standard `code-review` skill)
- Documentation-only PRs
- Formatting/linting changes

## The Three Perspectives
| Agent | Mindset | Question | Owns |
| ----- | ------- | -------- | ---- |
| **Advocate** | "Why is this correct?" | Trust boundaries, design rationale, false-positive defense | Correctness defense |
| **Skeptic** | "How can I break this?" | Bugs, edge cases, code smells that indicate bugs | Correctness attack |
| **Architect** | "Is this the right direction?" | System impact, scope, structural smells, tech debt | Direction |

## Workflow
### Phase 1: Gather Context
1. **Identify the changes** — PR diff, local changes, or specific files

The line at the top of this page pins the label git:20260728.80a7ab6, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
