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

With no annotations, the description carries the full behavioral burden and it does not disclose what happens when the receipt_id is unknown, whether any auth/scope is required, or whether results are cached/immutable. 'Stored' hints at persistence but nothing more.

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?

A single tight sentence with the resource front-loaded after the verb. No waste, though it is almost too terse for a tool whose domain term 'verdict receipt' is unexplained.

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 single-parameter read tool with no output schema and no annotations, the description is workable but thin: it never clarifies what a 'verdict receipt' contains or how it differs from sibling outputs. Adequate minimum, not more.

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 coverage is 0%, but there is only one required string parameter and the description's 'by id' maps directly onto receipt_id, conveying the lookup semantics. It adds no format, source, or example detail beyond the obvious, so it is only minimally compensating for the schema gap.

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?

States a specific verb ('Fetch') and resource ('stored verdict receipt') with the lookup key ('by id'), so the agent knows this is a retrieval-by-identifier operation. It does not contrast itself against siblings genesis_pin or verify_candidate, 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?

No guidance on when to use this versus verify_candidate or genesis_pin, and no prerequisites or exclusions stated. The agent must infer the retrieval context entirely.

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