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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=true, so safety is covered. The description adds genuinely useful behavioral detail beyond that: the response shape { count, next_skip, items }, the pagination loop, and the GET /task-groups endpoint.

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?

It is dense and front-loaded: identity, return shape, paging, single-record read, filtering, endpoint. The opening fragment 'Task groups (columns/lists on a task board)' is terse but purposeful; nothing is wasted.

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 7-parameter, no-output-schema list tool, the description supplies the return shape, the pagination loop, and both filter mechanisms. Combined with the annotations and full schema coverage, an agent has what it needs to call it correctly.

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%, so baseline would be 3. The description earns extra by explaining the pagination contract ('pass next_skip as skip for the next page') and summarizing the two filtering modes (exact-match filters vs MongoDB-style query) that the schema documents in detail.

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 names the resource and clarifies it as 'columns/lists on a task board', so the agent knows exactly what entity is being listed. It's a clear list operation but doesn't explicitly contrast itself with siblings like plutio_list_task_boards or plutio_list_tasks.

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 states concrete usage paths: 'Pass id to read one record' and 'Filter with exact-match fields or a MongoDB-style query', giving the agent clear invocation context. It stops short of stating when NOT to use it or naming an alternative sibling.

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