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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description still adds genuine behavioral context beyond that: newest-first ordering, that answers are excluded, and that the access link is never returned. It does not mention pagination defaults or result volume, so it is strong but not exhaustive.

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-loaded with the core purpose and tag, then the filters, then the cross-tool routing. Every sentence carries information, though the dense em-dash phrasing and embedded example make it slightly harder to scan than a clean bulleted split.

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 the description compensates by stating exactly what a row contains (delivery state only) and what it omits (answers, access link). For a read-only filtered list with zero required parameters, nothing needed to call it correctly 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 0%, so the description must carry the parameters, and it explains person_id ('who fills it'), form_id, and enumerates every status value with its meaning. Only limit and offset go unexplained, and those are conventional pagination controls.

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 framing: 'Who was SENT which form and what happened to it — newest first. Read-only.' It distinguishes itself from hr_get_form_response (answers live there) and hr_assign_form (the link lives there), so an agent can separate this list tool from its closest siblings without opening a 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?

Explicit routing: to read actual answers, call hr_get_form_response with the row's own id; to obtain the access link, look at hr_assign_form's result. It also gives a concrete decision scenario ('did the mentor ever fill the day-3 review') with the exact status value that answers it, and lists the accepted status filters.

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