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

No annotations are provided, so the description carries the full burden of behavioral disclosure. 'Retrieve all' implies a read-only operation, but nothing is said about ordering, pagination, permissions, or what happens when the task has no checklist items.

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 short sentences, front-loaded with the purpose and followed by the required inputs. There is minor redundancy in restating the required parameters, but nothing wasteful.

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 two-parameter read tool with complete schema coverage this is roughly sufficient, but with no output schema and no annotations the description could have described the returned checklist item shape and any ordering guarantees. It leaves those gaps unaddressed.

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 description coverage is 100%, so both board_id and task_number are already documented in the schema with their meanings. The description only restates that both are required, adding no format or scoping detail beyond the structured fields.

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 ('retrieve all checklist items for a specific task'), which clearly separates it from its write siblings add_checklist_item, update_checklist_item, and delete_checklist_item. It does not name those siblings explicitly, but the read/list distinction is unambiguous.

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?

'Use this to retrieve all checklist items for a specific task' gives the context of use, and the second sentence states the required inputs. There are no exclusions, prerequisites, or named alternatives, so usage is implied rather than fully guided.

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