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

No annotations are present, so the description carries the full burden of behavioral disclosure. It communicates that the operation is a verification and produces cryptographic proof, but it does not describe the response format, failure behavior, whether the operation is read-only, or any access requirements.

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 a single, front-loaded sentence with a clarifying em-dash clause. Every word contributes meaning, and there is no redundant or filler content.

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?

For a one-parameter tool, the description covers the core action and purpose. However, with no annotations and no output schema, it omits the result shape, failure behavior, and explicit invocation context, leaving the agent to infer important call-time details.

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%, since the schema already explains agent_id as 'Agent identifier to verify'. The description adds context about hash-chain integrity but no additional parameter format, type, or usage specifics, so the baseline of 3 applies.

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 action ('Verify'), a precise resource ('agent's hash chain integrity'), and the intended result ('cryptographic proof of untampered history'). It is clearly distinct from the sibling soul_* tools, which target profile, insights, leaderboard, feed, and bounties.

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 the tool should be used when an agent needs proof that its history has not been tampered with, but it does not explicitly state when to prefer it over alternatives, any prerequisites, or when not to use it.

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