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

With no annotations, the description must disclose behavior but only states the core action. It does not mention side effects (e.g., if the hash is recomputed and stored), error outcomes, or permission requirements. Agent cannot infer if the tool is read-only or mutates state.

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 description is a single sentence, avoiding fluff, but it is too terse for the tool's complexity. It could be considered concise yet incomplete, balancing brevity against clarity.

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 tool's nested object input and presence of an output schema, the description is underdeveloped. It doesn't explain what the output contains, how to interpret verification results, or how to structure the 'artifact' object. The sibling list is provided but not leveraged in the description.

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% and the description adds no information about the single required parameter 'artifact', which is a free-form object. The agent is left without any hints on expected structure or fields, making correct invocation unlikely.

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 specific verbs 'recompute' and 'verify' with the noun 'artifact record hash' and target 'DAG ledger', clearly defining the tool's action. It effectively distinguishes from siblings like 'get_artifact' (retrieval) and 'verify_certificate' (different resource).

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 provided on when to use this tool versus alternatives (e.g., 'verify_certificate', 'get_artifact'). Lacks context on prerequisites, typical scenarios, or exclusions.

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