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

No annotations are provided, so the description carries the full burden, yet it discloses nothing beyond the bare action. It does not say whether verification returns a boolean, throws on invalid signatures, or what trust anchor is used, and it says nothing about idempotency or side effects.

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?

One short sentence with no filler, so nothing is wasted. However, the brevity is under-specification rather than efficiency — there is no front-loaded detail to structure.

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 tool whose only input is an opaque nested object, with no annotations and no output schema, the description leaves the agent without the structure of the certificate, the success/failure semantics, or the return shape. It is not sufficient to invoke the tool correctly without guesswork.

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 single parameter is an untyped nested object, so the schema offers essentially no semantics. The description only echoes the parameter by mentioning 'certificate signature' and never explains the expected structure, encoding, or required fields of the certificate object.

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 ('Verify') and resource ('continuity certificate signature'), so the agent knows the operation is a validation of a certificate's signature rather than a mutation or lookup. It does not differentiate itself from siblings such as continuity_reliance_check, which could plausibly also be a validation step.

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 no guidance on when to call this versus continuity_reliance_check or the other continuity_* tools, nor any prerequisites (e.g., a certificate must first be issued). The agent must infer the calling context entirely from the name.

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