twake_mail_read

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

No annotations are provided, so the description bears full responsibility for behavioral disclosure. It only says 'read' and does not mention whether the operation is side-effect free, whether it can alter read/unread state, what authorization is needed, or what the response contains. For a simple read some of this is inferable, but the description adds almost nothing beyond the tool name.

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?

One compact sentence that front-loads the action and object, with no filler or repetition. Every word adds 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?

For a one-parameter read operation the minimal description is nearly sufficient: the agent knows what to call and what argument to supply. However, with no output schema and no annotations, a short note about the returned email content or side-effect neutrality would make it fully complete.

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% and the single 'id' parameter already has a description ('Email ID'). The tool description only echoes 'by ID' and adds no new format, example, or source details. Baseline 3 applies because the schema handles the parameter documentation.

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 states a specific verb ('Read'), a resource ('an email'), and a precise selector ('by ID from Twake Mail'). This makes it distinguishable from list-style siblings like twake_mail_inbox or twake_drive_read without needing to inspect their schemas.

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 phrase 'by ID' implies this tool should be used when the agent already has an email ID and needs that single email, but the description does not explicitly compare it with twake_mail_inbox or state when not to use it. Usage context is present only by implication.

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