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

Annotations already declare readOnlyHint=true and openWorldHint=false, so safety is covered. The description adds real behavioral context beyond them: only 'verified' items are returned, only from a 'finished' recording, and only if the signed-in person owns it — a meaningful filtering guarantee. It leaves open what happens when the recording is unfinished or unowned (error vs empty result) and whether unverified candidate items are omitted entirely.

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?

One dense sentence with zero filler: the scoping constraints come first and the payload contents follow in a colon list. Every clause — recording, ownership, owner, status, source link — carries information an agent would otherwise have to guess.

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, so the description usefully enumerates the returned fields (action, owner, status, source-line link), which an agent needs to plan a follow-up read. For a one-parameter, read-only tool this is nearly sufficient; only the empty/error case for an unprocessed or unowned recording is unstated.

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% and the single parameter already documents that it accepts an ID or a meetful.com/m/ link, so the schema carries the parameter burden. The description adds only the implicit constraint that the referenced recording must be finished and caller-owned. That is a mild addition above the baseline for full coverage.

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?

Uses a specific verb ('Returns') plus a specific resource ('verified commitments' / action items) and constrains scope to 'one finished recording the signed-in person owns'. An agent can separate this from get_notes or get_transcript by the word 'verified commitments'. It stops short of naming a sibling it is not, so the differentiator must be inferred from the resource noun.

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?

Usage is implied rather than stated: 'verified commitments' from 'one finished recording' presupposes the recording has finished processing and is owned by the caller. There is no explicit when-to-use, no exclusion such as 'use get_notes for raw notes' or 'use my_tasks for action items across all recordings'. The agent must reason about the prerequisite from the phrasing.

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