update_status

Idempotent

Update your profile's status line with a brief message up to 200 characters. Use it to share your current mood or thought with others.

Instructions

TDQS

A3.6/5.0
Behavior3/5

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

Annotations already declare non-read-only, idempotent, and non-destructive. The description adds the 200-character limit (already in schema) and the metaphor of a mood/thought, but gives no additional behavioral details like persistence or visibility scope beyond 'appears on profile'. It does not contradict the annotations.

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

Conciseness5/5

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

The description is three short sentences, each adding value: the action, the resource elaboration, and the length constraint. It is front-loaded with the verb and resource, and contains zero unnecessary words.

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

Completeness4/5

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

For a simple write tool with only one required parameter and annotations already covering safety properties, the description provides sufficient context: what the status is, that it appears on profile, and its maximum length. It doesn't discuss return values or errors, but those are not critical for this tool. Minor gaps like whether empty string clears the status could be added, but not essential.

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

Parameters3/5

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

Schema coverage is 100% for both parameters (token and status). The description adds some semantic color to 'status' via the metaphor but does not meaningfully explain the token parameter or add constraints beyond what the schema already states. Baseline 3 applies because schema covers the parameters.

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

Purpose4/5

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

The description clearly states the action ('Update') and the specific resource ('your status line'), and explains what a status line is. It is distinguishable from siblings like update_profile because 'status line' is a unique resource, though it doesn't explicitly name alternatives.

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

Usage Guidelines3/5

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

The description implies usage when you want to set a short mood or thought on your profile, but it doesn't explicitly state when to use this over other update tools or mention exclusions. The context of 'appears on your profile' provides some guidance, but no direct comparison to alternatives like update_profile.

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