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

Annotations declare readOnly=false, idempotentHint=true, destructiveHint=false, so the mutation/safety profile is covered. The description adds useful context: callback_url receives signed event POSTs, '' clears working_on. But it doesn't state auth requirements (member_token is required) or how updates merge vs. replace unmentioned fields.

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?

A single dense sentence with parenthetical clarifications. Front-loads the resource ('Your own seat settings') and each clause maps to a parameter group. Slightly cramped but no wasted words.

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 and 17% param coverage, the description should do more. It clarifies callback_url and working_on values but leaves agent_name vs display_name distinction, clearing behavior for names, and required-token auth unaddressed.

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 17% (only callback_url documented). The description compensates by explaining callback_url semantics (signed event POSTs, '' removes) and working_on (what you're doing now, '' clears it). But agent_name, display_name, room_id, and member_token get no added meaning beyond 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?

States specific verb+resource: 'Your own seat settings' with concrete fields (callback_url, display_name/agent_name, working_on). Clearly distinguishes itself as self-scoped ('Your own') vs. siblings like room_members or room_manage, though it doesn't name any sibling explicitly.

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?

Implied usage: this updates your own seat. The description hints at context (callback for services, working_on shown next to name) but never states when to use this vs. room_manage or other sibling tools, nor any prerequisites.

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