pumble_send_message

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

No annotations are provided; the description only notes the default user identity. It lacks disclosure of key behaviors such as rate limits, permissions required, error handling, or response format. The phrase 'by default' hints at the asBot option but does not fully describe behavioral traits.

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?

The description is a single sentence that is front-loaded with the action. It is concise and contains no extraneous information.

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?

Given no output schema and no annotations, the description is minimal. It does not explain return values or success/failure indicators, which would be helpful for a write operation. However, it is adequate for a simple send action.

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 100% (all parameters described), setting a baseline of 3. The description adds minimal extra value beyond the schema, only reinforcing the default identity. No new parameter semantics are introduced.

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?

The description clearly states the verb 'send', the resource 'Pumble channel', and the default scope 'as your own user'. It distinguishes from siblings like pumble_send_dm (direct message) and pumble_edit_message (edit).

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?

The description implies usage for sending messages to channels, but does not explicitly state when to use alternatives like pumble_send_dm for DMs or pumble_edit_message for edits. No when-not-to-use guidance is provided.

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