Reactivate Project User.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations provide basic safety info (non-read-only, non-destructive, non-idempotent, open world). The description adds only that it 'Reactivate[s] the specified User' and 'returns the modified object on success,' but fails to disclose specific behavioral traits like permission requirements, side effects, or exactly what reactivation changes. More context is needed.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is poorly structured, mixing a clear opening with irrelevant notes about 'OK Response' and redundant phrases about updating records. It is not concise; several sentences could be removed or reorganized for clarity.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The tool has no output schema, so the description should clarify return values and state changes. It mentions 'returns the modified object on success' but doesn't specify what fields are affected or what reactivation entails. Given the low complexity, the description is incomplete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Input schema has 100% coverage with clear descriptions for both parameters (project_id, id). The description merely lists them as required without adding meaning beyond the schema. Baseline score of 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description starts with 'Reactivate the specified User,' which clearly states the verb and resource. However, it then includes confusing text about 'update an existing Directory records' and 'Updates the specified Directory records,' diluting the primary purpose and potentially misleading the agent.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is provided on when to use this tool versus alternatives. The description includes a misleading instruction to 'Use this to update an existing Directory records,' which contradicts the tool's reactivation purpose. No when-to-use or when-not-to-use context is given.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
