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

Annotations already declare readOnly/openWorld/idempotent/non-destructive, and the description adds real value on top: the 20-questions-per-project-per-hour server limit, the shared docs knowledge base source of answers, and that the response JSON is passed through unchanged. Only minor gap is that it does not say how to interpret an answer that the docs KB cannot cover.

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?

Front-loads purpose and 'last-resort' framing, then the routing rule, then the parameter, limit, alias and response note. Dense and list-like, but every clause carries actionable information with no filler.

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 read-only, single-question tool with no output schema, the description covers source of truth, rate limit, and response passthrough. What remains thin is parameter-level guidance for composing the question, though the auth parameters are self-documented in the schema.

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 67% and the two auth parameters already carry their own descriptions. The description's note on 'question' merely restates the required flag and 2000-character cap from the schema, adding no guidance on how to shape a good question or what makes one answerable.

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 (open-ended question), resource (TestChimp platform docs), and the exact topic scope (purpose, philosophy, intended testing approach). It is clearly the only knowledge-base QA tool among siblings, distinct from ask-user-question-async which asks a human.

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?

Explicitly says to prefer references/ and agent-quick-answers first and to use this only when those do not cover platform intent or approach clarification. Both the when and the when-not, plus the alternative source, are named outright.

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