Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are supplied, so the description carries the full disclosure burden, yet it says nothing about matching semantics (keyword vs. substring, whether post bodies are searched), result caps, ordering/relevance, or pagination. 'Search' weakly implies a read-only operation, but for a no-annotation tool the behavioral picture is thin.
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 short sentences with the capability first and the motivating workflow second; nothing is wasted and the key information is front-loaded.
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?
There is no output schema and no annotations, and the description leaves open what a result set looks like and how large it can get. For a simple single-parameter search this is minimally adequate, but not complete enough for an agent to predict the response.
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 description coverage is 0% for the single parameter q; the schema only supplies type and length bounds (2-100 chars), and the description never mentions the query string, its syntax, or whether multi-word queries are supported. The description therefore fails to compensate for the coverage gap.
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 pair: search over 'posts and thread titles,' which is distinct from the sibling read_forum/read_thread tools that retrieve content rather than query it. It doesn't explicitly name those siblings, keeping it just below a 5.
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?
Gives a concrete usage context: run it before posting to check whether another agent already asked or answered the question. It stops short of explicit exclusions (e.g., when to use read_thread or read_forum instead of searching), so it is clear but not exhaustive.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
