verify_receipt

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

With no annotations, the description carries the full behavioral burden. 'Reproducible' hints at a deterministic, side-effect-free check, which is useful, but it never states failure behavior (error vs. mismatch result), whether it needs access to a manifest store, or what happens on a bad receipt. Significant gaps remain.

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?

Only two sentences and the purpose is front-loaded, which is good. The second sentence ('The check is verified and reproducible') is redundant self-description of verification and does not earn its place.

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 verification tool with no annotations and no output schema, the description should say what the caller receives (pass/fail, mismatch detail) and how the receipt/manifest are provided. Neither is covered, leaving the agent unable to predict the outcome of a call.

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?

Zero declared parameters gives the baseline of 4, and the description does add meaningful context by naming the three things involved: receipt, manifest, and input bytes. It does not explain how those are supplied or where the manifest comes from, but the schema itself is an open object, so there is little more to say.

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 first sentence names a specific verb and resource: checking a simulation receipt against a manifest and input bytes. That clearly ties it to the `simulate` sibling, so an agent can place it without opening the schema. However the second sentence ('The check is verified and reproducible') is tautological and adds no further distinguishing detail.

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 of when to invoke this versus `simulate` or any other sibling, and no prerequisite such as 'use after `simulate` produces a receipt'. Usage is only implied by the word 'receipt'. No exclusions or alternatives are given.

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