Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the burden of behavioral disclosure. It clearly states that it writes a file and modifies .gitignore, which are concrete side effects. However, it does not disclose whether it overwrites an existing apidog.json, appends to .gitignore, or requires any authentication or directory context. The transparency is partial but not deceptive.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
