wecom_get_doc_content

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

The description mentions 'Uses async polling internally', disclosing behavioral trait beyond what the schema provides (which only lists parameters). Without annotations, this is valuable. It also implies the tool may return partial results initially.

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?

Two sentences, concise and front-loaded with the purpose. The second sentence adds behavioral context. No waste.

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 no output schema and no annotations, the description could be improved by mentioning the return format (Markdown) and any limits. However, it covers the main purpose and polling nature adequately.

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?

Schema coverage is 100%, so the schema already documents both parameters. The description adds that task_id is for polling and implies it should be omitted on first call, but this is already in the schema description. So baseline 3.

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 'Fetch the full content of a WeCom online doc as Markdown', which is a specific verb ('Fetch') and resource ('WeCom online doc'). It also distinguishes from siblings like wecom_read_doc likely by focusing on full content and Markdown format.

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 says 'Uses async polling internally', which implies it is for getting full content and may require an initial call with just url and then polling with task_id. However, it does not explicitly state when to use this vs siblings or when not to use it.

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