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

No annotations are present, and the description only exposes a GET method, which weakly implies a read-only operation. It does not disclose side effects, whether a lockfile is created or stored, authentication requirements, or failure behavior.

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 definition is extremely brief and technically front-loaded, but it is under-specified rather than concise. The trailing '.' after 'receipt_id=' reads like a placeholder or stub, and no sentence explains behavior or context.

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 GET with an output schema, the endpoint line provides the minimum call shape. However, with no annotations, no parameter description, and a large sibling set, the description is not complete enough for reliable tool selection or correct parameter construction.

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 zero description coverage, and the only parameter 'receipt_id' appears in the path with no explanation of its format, provenance, or valid values. The description repeats the query parameter name but adds no semantic meaning beyond what the schema already provides.

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 an explicit HTTP verb and resource path ('GET /v1/provenance/lockfile') and shows the key input, so an agent can infer it retrieves or emits a lockfile for a receipt. It does not explain this in plain language or differentiate itself from siblings like hydracept_verify_lockfile, so it stops short of a 5.

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 statement about when to call this tool, what scenario requires emitting a lockfile, or why it should be preferred over alternatives such as hydracept_verify_lockfile or hydracept_get_receipt. The only context is the endpoint itself, so no explicit usage guidance is provided.

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