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

Annotations already indicate readOnlyHint=true, openWorldHint=false, idempotentHint=true, and destructiveHint=false, so the tool is safe and non-mutating. The description adds context that it is 'zero-input' and 'public', which are useful behavioral details beyond annotations, but does not disclose any output format details or additional side effects (though the output schema is available).

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 a single, concise sentence that front-loads the purpose and includes key qualifiers ('zero-input', 'public', 'founder or leader', 'local context'). No wasted words; every part adds value.

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?

Given the tool has zero parameters and an output schema exists, the description adequately covers the tool's purpose and scope. It mentions the target audience (founder/leader), the subject (InfoAddict engagement), and the mode (using local context). One could argue it could mention what the bundle looks like, but with an output schema, the burden is lighter.

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?

The tool has zero parameters, and the schema is empty with 100% coverage (vacuously). The description clearly states it is 'zero-input', which is sufficient. Since there are no parameters to explain, a baseline of 4 is appropriate given the schema is fully described and the description confirms zero-input.

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 clearly states the tool returns a bundle for assessing InfoAddict engagement fit, using a specific verb ('Return') and resource ('evidence and instruction bundle'). It distinguishes itself from siblings like assess_dan_role_fit by targeting InfoAddict specifically, though it could be clearer about what 'engagement fit' means.

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?

The description implies it should be used when a founder or leader wants to assess an InfoAddict engagement, but it does not explicitly state when to use this tool over alternatives like assess_dan_role_fit or other siblings. It mentions 'using its own local context' but provides no exclusions or alternative guidance.

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