# /doublecheck — Critical Verification Pass
**Usage**: `/doublecheck $ARGUMENTS`
## Current State
- Recent changes: !`git diff HEAD --stat | tail -5`
- Recent commits: !`git log --oneline -5`
- Tool versions: !`grep 'var version' cmd/*/main.go 2>/dev/null`
**Examples**:
```
/doublecheck # verify whatever was just implemented (tool inferred from context)
/doublecheck morpheus # verify morpheus implementation
/doublecheck oracle # verify oracle implementation
/doublecheck trinity # verify trinity implementation
/doublecheck neo # verify neo implementation
/doublecheck plan oracle # attack a plan before implementation begins
```

## What This Command Does
Runs an adversarial verification pass on a tool implementation or plan in the Go monorepo. This is NOT a confirmation pass — it is a structured search for problems. Four subagents attack from different angles simultaneously.
**This command is different from `/audit`.**
- `/audit` asks: "Are the context files accurate against ground truth?"
- `/doublecheck` asks: "Is the implementation itself complete, correct, and production-ready?"
> **Critical**: "Looks good" and "seems correct" are forbidden. Every agent must produce specific findings or justify exactly why each check passed. Absence of findings is suspicious — look harder.
