Where Context7 fits in the workflow
  1. 2
    Make the agent reach for docs

    Servers do not get used just because they are installed. Say so in CLAUDE.md, or the agent falls back on training data exactly when it matters most.

    Prompt · CLAUDE.md rule
    Before writing code against any library, framework, or SDK, look up its
current documentation with Context7. This applies even to libraries you
know well: the API may have changed since training. Do not skip it because
the change looks like a one-liner.
