Verification · Finding validation
External contract verification
Checks claims about third-party behaviour (an API can return null, a library throws) against authoritative documentation, and grades how strong that proof is.
Sub-techniques
-
Documentation lookup
V1044.001Fetch the exact library version's documentation or source.
-
Proof grading
V1044.002Grade as definitive (spec or exhaustive enum), illustrative (an example) or unresolved.
How to build it
- Resolve the dependency version from the lockfile.
- Fetch that version's docs or source, not the latest.
- Keep findings that rest on illustrative proof at lower severity.
Signals in a repository
- Documentation MCP servers or doc lookup tools configured for the review agent.
