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

Annotations already declare readOnlyHint, idempotentHint, non-destructive and openWorldHint=false, so safety is covered. The description adds genuinely useful behavior: results are ordered newest first, and the returned fields (meeting_id, title, date, platform, summary-exists) are disclosed in the absence of an output schema.

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?

Three short sentences, front-loaded with the core action, then filters, then return shape. No filler and nothing buried.

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 usefully enumerates the returned fields, and annotations cover the safety profile. It omits pagination behavior (default/max limit) and any routing versus search_meetings, which are the remaining gaps for a simple list tool.

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%, so all four parameters (to, from, limit, title) are already documented in the schema. The description maps loosely onto the filters ('date range or a word in the title') but adds no format or boundary detail beyond that, so baseline 3 is appropriate.

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 (list the user's recorded meetings) plus ordering (newest first), filterability, and return fields. However, it never distinguishes this tool from the sibling search_meetings, and 'filter by a word in the title' sounds like search, so an agent cannot fully disambiguate the two from the description alone.

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: when you want recorded meetings, optionally narrowed by date range or title text. There is no explicit when-to-use/when-not guidance and no mention of the sibling search_meetings, which overlaps heavily with the described filtering behavior.

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