contract-acquisition

Acquire a platform's or library's real contract from its own toolchain oracles before authoring against an unfamiliar one — infrastructure, a CLI invocation, code on a managed runtime, or code against an unfamiliar framework or third-party library whose contract you don't hold. Triggers on "deploy to", "write the Terraform / Pulumi / CDK for", "provision", "what's the right resource shape", "why does this apply fail", "what's the signature / does this still exist in this version", "why does this library call raise". Runs a tiered, tool-keyed protocol — detect the stack or library + version, run the toolchain's validate / plan / synth or the type-checker / compiler + API-surface oracle, consult a curated skill, retrieve versioned docs, then a runtime probe — declares its oracle tier and degrades honestly to the probe when no strong static oracle exists. Do NOT use for code whose contract you already hold (use work-loop directly), nor to review a finished diff (rides quality-engineer).
