list_api_docs

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

With no annotations provided, the description must disclose behavioral traits. It mentions 'cached' but does not explain implications like staleness, refresh mechanism, rate limits, authorization requirements, or side effects. The agent gets minimal insight beyond the fact that it is a list operation.

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 sentence of 8 words, front-loading the key action and resource. Every word is essential, with no filler. It is perfectly concise and well-structured.

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 simple list tool with one optional parameter and no output schema, the description covers the essential purpose and filtering. Minor gaps include lack of return format information, but it is sufficient for an agent to understand the basic function.

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?

Parameter coverage is 100% as the schema describes 'category' as a filter. The description adds the word 'optionally' but does not provide new meaning beyond the schema. Baseline 3 is appropriate since the schema already does the work.

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 verb 'List' and the resource 'cached Mailganer API documentation pages', with optional category filtering. It distinguishes from sibling tools like 'search_api_docs' or 'get_api_endpoint_doc' by indicating a broad listing action. This is specific and unambiguous.

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 given on when to use this tool versus alternatives. Sibling tools like 'search_api_docs' or 'get_api_overview' are not mentioned, nor are any preferred scenarios or exclusions. The description lacks contextual usage advice.

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