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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint, so safety is covered; the description's "read-only" restates that. It does add genuine behavioral context the annotations lack: the same-account existence constraint on project_id. Pagination and return-shape behavior remain undisclosed.

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 sentences, no filler, and the scope statement is front-loaded before the usage hint and limitations. Efficient for a tool with this many parameters.

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 full annotation coverage and no output schema, the description supplies what an agent needs: the endpoint scope, the filter dimensions, the usage trigger, and the account-context precondition. Remaining gaps (pagination, return shape) are minor against what annotations already carry.

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 78%, so the schema documents most parameters already. The description names project_id and repeats the filter enum values (ALL, ACTIVE, ARCHIVED) that are already in the schema, while saying nothing about page, page_size, account_id, or the auth parameters — marginal value beyond 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 (Lists) and resource (tasks from /tasks) plus the optional scoping dimensions (project_id, status filter). An agent can distinguish it from get_task and list_task_comments, though it never names the closest sibling, list_user_tasks, to draw the line.

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 after selecting a project to narrow task context" gives a clear when-to-use trigger, and the Limitations clause adds the precondition that project_id must exist in the same account context. It stops short of naming an alternative (e.g. list_user_tasks) for the non-project-scoped case.

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