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

Annotations already declare readOnlyHint=true, so the safety profile is covered; the description adds real value by disclosing the returned structure (per-action records with time, IP, location, email status) and the underlying GET endpoint, which is important since no output schema exists. It does not mention ordering, pagination, or auth/rate-limit behavior.

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?

Two dense sentences, zero filler, payload description front-loaded ahead of the endpoint reference. Every clause carries information an agent can use.

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 read-only, single-parameter tool with no output schema, describing the returned audit-trail fields is the key missing piece and it is present. Minor gaps remain: ordering/pagination of the action list and any error behavior for unknown ids.

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?

Single parameter with 100% schema description coverage, including a hint on where to obtain the id ('from stiply_list_sign_requests'). The description itself adds nothing about the id beyond the schema, so baseline 3 applies.

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 and resource ('Get the audit trail of a sign request') and enumerates the payload ('each action (sent, opened, signed, ...) with time, IP, location and email status'), which inherently separates it from the plain get-by-id sibling. It does not explicitly name stiply_get_sign_request as the alternative, so an agent must infer the division of labor.

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?

Usage is only implied: you call this when you want to see the progression of a sign request. There is no explicit when-to-use/when-not guidance and no mention of how it relates to siblings like stiply_get_sign_request, stiply_get_sign_request_by_external_key, or stiply_list_signers.

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