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

Annotations already indicate read-only, idempotent, and non-destructive behavior conocimiento. The description adds value by specifying the return format (JSON validity result), offline verification capability, compliance (GDPR), and cost. This goes beyond annotations by providing operational and compliance context.

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 concise (three sentences) and front-loaded with the core action. The compliance and cost details are useful but placed at the end, which is acceptable. No wasted words, but could be slightly more structured with a clear use-case statement.

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 (1 parameter, output schema present), the description is adequate. It covers key aspects: what it does, output type, offline capability, compliance, and cost. With the output schema and annotations, the agent has enough to invoke it correctly. It lacks explicit error scenarios or edge cases, but those are not critical for this context.

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 100%, so the parameter 'envelope' is already described. The description does not add further detail about the envelope structure or required fields beyond what the schema provides万余字. It meets the baseline but does not exceed it.

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 verifies a memory attestation envelope against the platform key registry. It identifies the specific action (verify), the resource (attestation envelope), and the context (platform key registry). However, it could better distinguish from siblings like verify_agent_attestation, though the 'memory' prefix provides some differentiation.

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 implies usage for verifying envelopes and mentions offline verification, but it does not explicitly state when to use this tool versus alternatives like verify_agent_attestation or when not to use it. No prerequisites or specific conditions are provided.

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