Agent Card Health Check

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

No annotations are provided, so the description carries the full behavioral burden. It implies a diagnostic read/verification operation but does not disclose whether it makes live network calls, requires credentials, has side effects, rate limits, or how failures are reported. For a tool that reconciles declarations against live connection results, this is a significant gap.

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?

A single densely packed sentence with no padding. It is front-loaded with the core action, though the compound phrasing slightly reduces immediate clarity.

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?

With no annotations, no output schema, 3 parameters at 0% schema coverage, and nested objects, the description is far too thin. It omits what the comparison returns, what a mismatch means, and how to supply credentials, leaving key operational details unaddressed.

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 required 'agentCard' and 'authorizedTargetUrl' plus optional 'authorization' object are entirely undocumented. The description references agents and connection results but does not explain the parameter meanings, formats, or the bearer credential structure, leaving the agent to infer.

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 states a specific verb (照合します - reconcile/compare) and resources (Agent Card declaration vs. actual non-update connection results). However, the phrasing is dense and the scope ('all or explicitly authorized A2A agents') is somewhat unclear, and there is no sibling differentiation since none exist. Purpose is recoverable but not crisp.

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?

There is no explicit when-to-use guidance or indication of when-not to use this tool. The mention of authorization scope hints at a condition, but it does not tell the agent when to select this diagnostic over alternatives or what prerequisites apply.

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