Behavior3/5

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

Annotations already declare this is a non-read-only, open-world, non-destructive write. The description usefully adds the public-visibility trait and a 60-character limit, but says nothing about whether it overwrites a previous status or what happens on auth failure.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

One short sentence with no padding, and the key constraint and example come immediately. It is a fragment rather than a complete statement, but nothing is wasted.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a two-parameter write tool with annotations and no output schema, the essentials are nearly covered. Missing is any note on overwrite semantics, required membership/join state, or the effect of exceeding the character limit.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is only 50%: accessToken is documented in the schema, but `status` has no schema description. The description compensates with a length constraint (≤60 chars) and a concrete example, which the schema does not enforce or illustrate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose2/5

Does the description clearly state what the tool does and how it differs from similar tools?

The text reads as a parameter definition ("Short public status shown next to your name") rather than a statement of what the tool does. The action verb survives only in the name/title, so the description largely restates the field rather than the operation.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance on when to call this versus siblings like update_profile or set_avatar, and no mention of prerequisites such as having joined. The accessToken requirement is only visible in the schema, not the description.

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