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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It states that the operation is a one-way hash ('Hash') and that details are hidden, but it does not disclose whether the commitment is stored, whether anchoring via anchor_status is required, or any security or side effects. This is minimal for a ZK-related tool.

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 short, front-loaded sentences with no fluff. Every word serves a purpose.

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 lack of annotations and output schema, the description is incomplete. It does not explain what the tool returns (e.g., a commitment or proof), how it interacts with sibling tools like verify_commitment or anchor_status, or any prerequisites. For a simple one-parameter tool, an agent still needs more context to invoke it correctly.

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 schema has one parameter, entity_id, with 0% schema description coverage. The description does not mention entity_id at all, so it adds no meaning about how the parameter is used. The phrase 'compliance status' only indirectly relates to the entity, leaving the agent to guess the parameter's role.

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 uses a specific verb ('Hash compliance status into ZK commitment') and clearly identifies the resource (compliance status → ZK commitment). It also distinguishes itself from sibling tools like create_vc, build_merkle_tree, and verify_commitment by focusing on creating a privacy-preserving commitment.

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 phrase 'Proves state without revealing details' implies when to use the tool, but there is no explicit when-to-use guidance, no exclusions, and no mention of alternatives such as create_vc, threshold_proof, or selective_disclosure. The usage context is inferred rather than stated.

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