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

With no annotations present, the description carries the full burden of disclosing behavior. It states what the tool computes (recompute digest), what it verifies (frozen implementation/input integrity), and what it intentionally does not do (semantic replay). While it does not describe return values or side effects, the read-only nature of 'verify' and the explicit scope make the behavior reasonably transparent.

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 two sentences, front-loaded with the primary action, and every phrase adds distinct information. It is concise without being underspecified, delivering the core purpose and key exclusions in under 25 words.

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 modest complexity—one parameter, no output schema—the description covers the essential scope and limitations. The caveat about semantic replay adds necessary context for correct use within the Athena toolkit. However, the absence of any indication of the return value or success/failure behavior leaves a minor completeness gap.

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 only one parameter, invocation_id, with 0% description coverage. The description does not explain what invocation_id refers to or how to obtain it. Although the parameter name is moderately self-explanatory, the description adds zero semantic value about the parameter, so it fails to compensate for the low schema coverage.

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 opens with a specific verb ('Recompute') and resource ('HUGINV packet digest'), clearly stating the tool's function. It further distinguishes the tool from siblings by narrowing its scope to 'frozen implementation/input integrity only' and explicitly excluding semantic replay, which separates it from related verification tools.

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?

The description gives clear context for when to use the tool: to verify a frozen packet's integrity. It also provides an exclusion condition ('semantic replay is N/A unless a real registered executor replays the algorithm'), though it does not explicitly name alternative tools. This is sufficient guidance for a specialized verification action.

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