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

Annotations already declare readOnlyHint=true, openWorldHint=true, destructiveHint=false, so the safety profile needs no restating. The description adds the underlying endpoint (GET /clientapis/capamanagement/v1.0/capa/{id}/tasks) and a preview of the returned fields, which is useful, but says nothing about pagination totals, rate limits, or what happens when a CAPA has no tasks.

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?

Three short sentences with zero padding. The purpose and returned fields come first, the id provenance second, and the endpoint last — a clean front-loaded 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 read-only list tool with no output schema, the field enumeration effectively substitutes for return-value documentation, and pagination is covered by the schema. It stops short of explaining ordering, empty-result behavior, or pagination totals, which leaves a small gap for an openWorldHint listing tool.

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 page/page_size defaults and limits are fully documented in the schema, so the baseline is 3. The description adds genuine value beyond the schema by specifying that the `id` is the GUID `Id` returned from safetychain_search_capas, giving the agent a sourcing path the schema doesn't provide.

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 ("List a CAPA's tasks") and enumerates the returned task attributes (step, form, location, resource, workgroup, assignee, due date, status), which in practice separates it from get_capa_activity, get_capa_attachments and get_capa_history. It never explicitly contrasts itself with those siblings, so the differentiation is inferential rather than stated.

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?

Gives a concrete prerequisite chain: the `id` must be the GUID `Id` obtained from safetychain_search_capas, which tells the agent how to reach this tool. It does not describe when to prefer get_capa_activity or get_capa_attachments instead, so no exclusions or alternatives are stated.

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