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

With no annotations, the description does carry real behavioral weight: it discloses that the message is public ('everyone in the room sees it') and that authorship is attributed to this agent under its own name. It says nothing about prerequisites (must be in the meeting), rate limits, persistence, or failure modes for a write operation.

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 short sentences, zero filler, with the core action front-loaded and the visibility consequence placed second where it belongs.

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?

For a two-parameter write tool with no annotations and no output schema, the description covers what happens but not what is required to call it successfully — the meeting identifier format and any join/authorization prerequisite are left 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 coverage is 0% — neither parameter has a description — and the description does not compensate. It never clarifies what 'meeting' expects (ID, code, or name) or whether 'text' has length or formatting constraints.

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 target: post a message into the meeting chat, attributed to this agent. It implicitly distinguishes itself from voice-oriented siblings like speak and from send_feedback/send_notetaker by naming 'meeting chat', though it never names an alternative outright.

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 only implied — you use this when you want to say something in a meeting's chat. There is no explicit when-to-use versus speak (voice) or send_feedback, and no stated prerequisite such as having joined the meeting first.

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