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

No annotations are provided, so the description carries full burden. It discloses only the basic action (send) and protocol, but nothing about side effects, authentication requirements, or what happens on failure. For a write-intended operation, this lacks needed context.

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 precise sentence with no wase; the protocol mention adds context without bloat. Every word earns its place.

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 simple two-parameter send operation with no output schema, the description plus schema cover the essential information. It falls slightly short on usage context, but none of the missing details block basic invocation.

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% – both 'room' and 'message' are documented in the schema. The description adds no extra meaning about parameter formats, defaults, or constraints, so baseline 3 applies.

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 ('Send'), a resource ('a message to a Twake Chat room'), and a protocol ('via Matrix') – clearly distinct from siblings that list rooms or read history. An agent can immediately understand what this tool does without needing to inspect other definitions.

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?

No guidance on when to use this tool versus alternatives; the description only says what it does. The distinction from siblings is implied by the verb, but there is no explicit 'use this when...' or exclusion to prevent incorrect selection.

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