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

Annotations already declare readOnly, idempotent, closed-world, non-destructive, so the safety profile is covered. The description adds useful context the annotations don't: fixed set size (37), source-linked provenance, and no input required. It stops short of describing the shape of what comes back, which matters somewhat since there is no output schema.

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?

A single sentence, front-loaded with the enumerating scope, followed by topic coverage and the routing rule. Every clause carries information an agent needs.

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?

For a zero-param bulk-retrieval tool with read-only annotations, the description covers scope, size, and alternative. The only gap is the absence of any hint about the return payload's size/structure, which would help an agent decide whether to pull all 37 at once.

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?

Zero parameters, so baseline is 4. 'Takes no input' merely restates the empty schema rather than adding meaning, but nothing is missing.

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?

States a specific verb+resource (list all of Trimi's reviewed answers) plus scope: 'every one of the 37', 'in one call'. It also names the topical sibling it differs from, so an agent can distinguish it from search_questions without inspecting either schema.

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?

Explicit when-to-use ('when you need the whole reviewed set') and an explicit alternative ('use search_questions for one topic'). The exclusion is stated, not left to inference.

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