-### 2. Verify specs implementation
-
-Read the PR description and look for a **SPECS** section:
-
-```bash
-gh pr view $ARGUMENTS --json body --jq '.body'
-```
-
-If a SPECS section is present, it defines the requirements that this PR MUST implement. **Every single spec must be verified against the diff.**
-The specs override other instructions (code, inline comments in code, etc). ALL specs MUST be implemented.
-
-For each spec:
-1. **Find the code** that implements the spec
-2. **Verify correctness** — does the implementation fully satisfy the spec?
-3. **Check for missing specs** — is any spec not implemented at all?
-
-Flag any unimplemented or partially implemented spec as a **P1 finding** (missing functionality that was explicitly required).
-
-Include a spec coverage table in the review output:
-
-```markdown
-| Spec | Implemented | Location | Notes |
-|------|:-----------:|----------|-------|
-| Must support `--flag` option | Yes | `interp/api.go:42` | Fully implemented |
-| Must return exit code 2 on error | **No** | — | Not found in diff |
-```
-
-If no SPECS section is found in the PR description, skip this step.
