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

Annotations mark the tool as read-only, idempotent, and non-destructive. The description adds valuable context beyond that: dates come from current-cycle institution records and may lag, students should verify on official pages, and no student data is read or stored. This is strong behavioral disclosure.

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?

The description is three sentences with no wasted words: it front-loads the main purpose, then adds the prep schedule and calendar URL, then the data-freshness caveat and privacy note. The parenthetical schedule details are relevant and concise.

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?

Given that an output schema exists and annotations already cover safety and read-only behavior, the description provides sufficient operational context: college limit, returned artifacts, data lag warning, confirmation recommendation, and privacy. Nothing essential is missing for correct selection and invocation.

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?

The only parameter, unitids, is described in the schema as an IPEDS institution ID from search results, which provides core meaning. The description reinforces the 20-college limit but adds no further parameter detail. With 0% schema description coverage in the prose, the description is minimally adequate but does not substantially improve on the schema.

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 clearly identifies the tool as retrieving application, aid, and commitment deadlines for up to 20 colleges, with countdowns and a prep schedule. It is distinguished from sibling tools like get_financial_aid and get_university_details by its focus on deadlines.

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 description implies when to use it—when deadline info and a prep schedule are needed—but it does not explicitly contrast with sibling tools or state when not to use it. No alternative routing or exclusion conditions are provided.

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