list_feed_catalog

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

No annotations provided. The description only declares the action without disclosing behavioral traits such as idempotency, rate limits, or whether the catalog is static or dynamic.

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?

Single concise sentence with no waste. However, could be slightly more structured by including a brief note on the catalog's purpose.

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 zero parameters and no output schema, the description covers the essential purpose. It could mention that the catalog feeds are usable with other tools, but not mandatory.

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?

No parameters exist, so baseline score of 4 applies. The description adds no parameter info, which is acceptable given zero parameters and 100% schema coverage.

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 complete catalog of predefined news feeds, using specific verb 'returns' and resource 'catalog'. It distinguishes from sibling tools that fetch individual feeds or search.

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 on when to use this tool versus alternatives like fetch_feed or search tools. The description implies it's for listing available feeds, but no explicit context or exclusions.

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