gitee_send_message

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

No annotations are present, so the description must fully disclose behavior. It only states 'Send a private message' without disclosing side effects (e.g., mutating state), authentication requirements, rate limits, error handling for invalid usernames, or whether the message is stored.

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, concise sentence with no redundant information. It front-loads the action and resource appropriately, making it easy to scan.

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 tool, the description provides the core action. However, it lacks behavioral context (e.g., message limits, delivery guarantees) and does not explain the output (no output schema). It is minimally complete but could be improved.

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%, with clear parameter descriptions ('Recipient username', 'Message content'). The description adds no additional semantics beyond what the schema provides. Baseline 3 is appropriate since the schema already describes parameters well.

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' and the resource 'private message', which directly conveys the tool's action. Among sibling tools, there are get and list message functions, so this tool's purpose is distinct. However, it could be more descriptive about the recipient context.

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 is provided on when to use this tool versus alternatives (e.g., gitee_list_messages or gitee_mark_message_read). There is no mention of prerequisites, when not to use, or any conditions for successful sending.

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