| name | verify-proof |
| description | Verify candidate proofs with the local proof verification MCP service. Use only when a full candidate proof of the entire problem has been assembled in markdown, and before publishing the final verified blueprint. |
Verify Proof
Use the local proof verification service as the canonical verifier before accepting a solution.
Do not use this skill for partial proofs, isolated subgoals, or branches that have not yet produced a full proof draft of the whole problem.
Input Contract
Read:
- target theorem statement
- assembled proof blueprint candidate from
results/{problem_id}/blueprint.md as pure markdown text
- relevant prior failure reports and branch context
Procedure
- Read the current
results/{problem_id}/blueprint.md draft as pure text.
- First check that
blueprint.md contains a full proof draft of the entire target theorem rather than a partial proof, fragment, or exploratory notes. If it does not, do not call the verifier yet.
- Call MCP tool
verify_proof_service with:
statement: target informal statement
proof: the raw markdown text from blueprint.md
- Read
verification_report.summary, critical_errors, gaps, verdict, and repair_hints.
- Return and persist exactly what the verification service returns. Do not rename keys, add keys, or change the JSON structure.
- Treat the proof as failed if any of the following hold:
verdict is "wrong"
verification_report.critical_errors is non-empty
verification_report.gaps is non-empty
- Only treat the proof as passed when none of the failure conditions above hold.
- If the proof passes, rename
results/{problem_id}/blueprint.md to results/{problem_id}/blueprint_verified.md.
Output Contract
Append to verification_reports:
{
"verification_report": {
"summary": "string",
"critical_errors": [
{"location": "", "issue": "detailed description of the issue"}
],
"gaps": [
{"location": "", "issue": "detailed description of the gap"}
]
},
"verdict": "string",
"repair_hints": "string"
}
Persist the verification service response exactly as returned.
If verification fails, revise blueprint.md directly and append to failed_paths when a branch is invalidated.
