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

Annotations already disclose a non-read-only but non-destructive write, and the description adds the key behavior beyond them: the answers are persisted ('Your answers are saved for Tue'), so the agent knows this is a durable submission rather than a scratch call. It stops short of describing retention, overwrite behavior, or what form the returned guidance takes.

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?

Purpose is front-loaded in the first sentence and the field constraints follow in a single dense block with no filler. The one weakness is structure: the fields are packed into a run-on enumeration with a colon series, which is harder to scan than a short list would be.

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 4-parameter write tool with no output schema, the description covers purpose, prerequisites, all parameter constraints, and persistence behavior, which is most of what an agent needs. The remaining gap is what the returned guidance actually contains and whether re-submission overwrites prior answers.

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?

With 0% schema coverage, the description carries the full burden and does so: it marks which fields are required versus optional, gives length limits (2000 chars for answers, 100 for the other fields), specifies that answers must be one per question in order, and supplies sentinel values ('unknown'/'undisclosed') plus an explicit anti-guessing rule.

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 and resource ('Answer the questions from `or_problem_questions` and get guidance on solving the problem') and ties itself to a named sibling tool, so an agent knows exactly which tool precedes it. The dual function (submit answers, receive guidance) is explicit rather than implied.

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 prerequisite is clear: answers must correspond to questions produced by `or_problem_questions`, which establishes the ordering of calls. It does not explicitly say what to do if questions have not yet been generated or whether resubmission is allowed, so no true when-not guidance is given.

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