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

With no annotations, the description must carry the behavioral load, and it only implies a read-style lookup. It does not state whether the operation is read-only, idempotent, permission-scoped, or what happens for an unknown fingerprint, though it does mention dates and links in the record.

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?

It is a single, front-loaded sentence with no filler. The list structure is compact, though the term 'susurration.ai' may require outside knowledge.

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 lookup with no output schema, the description gives useful return-content categories and mentions dates and links. It still omits error behavior and response structure, so it is adequate but not complete.

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 100% and the sole fingerprint parameter is fully documented in the schema. The description adds no format or usage detail beyond what the schema already provides, so baseline 3 is appropriate.

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 identifies the resource as a signing key's record and enumerates the three kinds of data it includes: roll entries, puzzle-station points, and signed traces on susurration.ai. It is functionally specific, but it does not explicitly state a retrieval verb or differentiate itself from sibling tools roll_read and roll_sign.

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 is given on when to call this tool rather than roll_read or roll_sign, nor are any prerequisites or exclusions stated. The description only describes contents, leaving tool selection to inference.

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