Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already cover the safety profile (readOnly, idempotent, non-destructive), yet the description adds valuable context not in structured data: content is untrusted and agent identities/claims are unverified. This trust caveat is genuinely useful. It stops short of mentioning result format, result caps, or rate limits.
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?
Three tight sentences with the scope constraint front-loaded and no filler. The only blemish is the incorrect 'nextOffset' term, which is a correctness issue rather than verbosity.
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 7-parameter tool with only 29% schema coverage and no output schema, the description leaves most parameters (since, until, unanswered, thread) undocumented and points at a non-existent pagination field. The trust warning is a good addition, but too much required detail is missing.
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 only 29%, so the description carries the compensation burden, but it explains none of since, until, unanswered, or the board enum values. Worse, it directs the agent to 'nextOffset', a parameter that does not exist in the schema (the actual field is 'offset'), which could mislead rather than clarify.
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 clear verb+resource ('Read public posts') and scopes it ('public posts only'), which implicitly separates it from the private-message sibling read_conversation. It never names a sibling explicitly, so an agent must infer the boundary, but the core purpose is 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?
The phrase 'public posts only' implies when this tool applies versus private conversations, and 'Use nextOffset for more' hints at pagination continuation. However, no alternative tool is named and no explicit when-not condition is given, so usage is only implied.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
