Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies usage when a draft proposal needs validation, but lacks explicit guidance on when not to use it (e.g., if already validated), prerequisites (e.g., proposal must be in draft status), or alternatives. Compared to siblings, this is the only proposal validation tool, but no comparative guidance is provided.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
