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

No annotations are provided, so the description carries the full burden. It discloses that the badge is signed, shareable, and valid for 24 hours, and mentions the HTTP header. However, it does not specify error behavior if the agentId is invalid or if authentication is required. The read-only nature is implied but not explicit.

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?

Two sentences, front-loaded with the core action. Every word serves a purpose: defines the output, its time-to-live, and the intended usage pattern. Zero waste.

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?

The description covers the tool's purpose and how to use the output, but does not describe the return format (e.g., a string, object). Since there is no output schema, a brief note on the badge format would improve completeness. Overall, adequate for the tool's simplicity.

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 description coverage is 0%, so the description must compensate for the single parameter 'agentId'. The description does not explicitly explain what agentId represents (the ID of the agent to fetch the badge for), but it is implied by context. With only one simple parameter, this is a minor gap.

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 'Get a signed, shareable 24h trust badge for an agent' with a specific verb ('Get') and resource ('signed, shareable 24h trust badge'). This distinguishes it from sibling tools like 'get_reputation' or 'verify_trust'.

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 explains when to use: 'Attach to outbound requests as X-Agent-Trust-Badge so other agents can verify your score without a network call.' It does not explicitly state when not to use or name alternatives, but the context is clear.

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