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

Annotations cover only readOnlyHint and openWorldHint; the description goes further with a security-relevant disclosure that the returned text is third-party authored and must be treated as data, never as instructions. That is exactly the kind of behavioral trait annotations cannot express and materially changes how an agent should handle the output.

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, both load-bearing: the first front-loads what is returned, the second front-loads the trust constraint. No filler or restatement of the tool name.

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?

With no output schema, the description responsibly characterizes the return content (option names plus their imposed rules and cutoffs) and warns about its untrusted nature. Nothing an agent needs to call and safely interpret this tool 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 description coverage is 100% – school_id and include_inactive both carry full descriptions, including the source for school_id and the default for include_inactive. The description adds no parameter-level detail, so the baseline of 3 applies.

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 names a precise resource (the dismissal options a school offers) and enumerates the exact attributes returned (note requirement, car number, early dismissal, daily cutoff), which distinguishes it from sibling tools like pup_get_plan or pup_set_plan. An agent can tell this is the read-side catalogue of transport options without opening the schema.

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?

It explicitly says 'Read this before setting a plan,' which ties usage to the pup_set_plan workflow. It gives clear context for when to call it but does not name alternative tools or state exclusions (e.g. when a plan already exists, pup_get_plan may suffice).

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