mutualAuthVerifyTrustBundle

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

With no annotations provided, the description fully bears the responsibility for behavioral transparency. It clearly states the return format (ok:true on success, failure reason otherwise) and lists specific failure reasons (untrusted_publisher, signature_invalid, bundle_expired, not_yet_valid). This is good, though it doesn't mention if there are any side effects or performance costs.

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 two sentences long, front-loaded with the verb 'Verify', and every sentence adds value. No wasted words.

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?

Given the tool's simplicity and the lack of output schema, the description adequately covers return values and failure reasons. However, the 'bundle' parameter is a complex object with no property descriptions, which could be more complete. Overall, it's sufficient for a verification tool.

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?

The input schema has 100% description coverage for its three parameters. The description does not add any additional meaning beyond what the schema provides; it only references the bundle and trusted publishers. Baseline is 3, and no extra value is added.

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 tool's purpose: 'Verify a TrustAnchorBundle signature and freshness.' It specifies the action (verify) and the resource (TrustAnchorBundle), and distinguishes it from siblings by being focused on trust bundle verification.

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 provides no guidance on when to use this tool versus alternatives. Among siblings like verify_issuer, verify_delegation, etc., there is no comparison or context to help the agent choose correctly.

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