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

The annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=true, so the safety profile is covered. The description adds context beyond the annotations: it names the underlying GET endpoint and lists the response fields (id, title, prerequisites, triggers), which matters because there is no output schema. It does not discuss pagination or rate limits, and the schema covers those, so this is not a 5.

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 clauses with the core purpose first and the follow-up cue second; nothing is filler. The parenthetical field list is slightly compressed, but it still earns its place by compensating for the missing output schema.

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 simple read-only list tool, the description covers purpose, response shape, and the follow-up tool. With full schema coverage and clear annotations, nothing essential is absent, though a note on the pagination contract (next_page) would make it complete.

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 schema itself documents page, per_page, and workflow_id, so the baseline of 3 applies. The description only implies that one workflow is targeted; it adds no meaning to the paging parameters or to how workflow_id is chosen.

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 the specific resource (statuses of one pipeline workflow) and enumerates the returned fields, so it is distinguishable from cats_list_workflows and cats_list_job_statuses. It never uses a clear verb like 'list/return', relying instead on a noun phrase plus the raw endpoint, which keeps it short of a 5.

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?

It points the agent forward with 'Use the ids with cats_change_pipeline_status', which is a useful next-step cue. However, it gives no guidance on when to use this instead of cats_list_workflows or cats_list_job_statuses, and it states no prerequisites, such as needing a workflow id from cats_list_workflows. The usage guidance is implied rather than explicit.

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