What's Wrong?

When asked whether to keep a function in a public API, Claude provided
two justifications without verifying them against the actual code:

  1. Claimed "users might want custom formatting" - but the function

has fixed format with no customization options

  1. Claimed "users might want to format only errors" - but this requires

extra work that makes the function useless for this purpose

Claude invented plausible-sounding reasons instead of reading the
code first. This pattern wastes user time by presenting false options.

What Should Happen?

Expected behavior: Claude should verify claims against actual code
before presenting them as valid options.
