Whose pick this was

  • Write against the API that exists today

    The default move, and it is the right default. Version-pinned documentation fetched at the moment of writing, rather than recalled from whenever the model last saw this library. Worth pointing at the version the project actually installs, because "latest" is its own way of being wrong.

  • Read a codebase you did not write

    Fixes the failure that looks least like a context problem: the agent knows the library, just the version from its training data. Wrong API, confident tone, no error until runtime.

  • A review that is not a rubber stamp

    Then check the claims the diff makes about somebody else's library. Reviewing agents are worst at this exact thing, because the call looks idiomatic and the model has genuinely seen that API. It has seen an older one. Version-pinned documentation is what turns "looks right" into "is right for the version this project installs".
