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

Annotations only declare the safe-write profile (readOnlyHint=false, destructiveHint=false, openWorldHint=true). The description adds real behavioral context beyond them: it runs without confirmation, the task is scoped to your team, complete_task closes it, and it requires a Cotlet API key with app access. Return format is not described, keeping it short of 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?

Front-loaded with the core purpose and sized appropriately for the tool's simplicity. There is mild redundancy between 'New task in a项目 or standalone' and the following sentence that re-explains the same project/standalone split, and the 'Runs without asking' phrasing is slightly cryptic, but overall it is tight.

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 create tool with no output schema and a fully documented schema, the description covers the essentials an agent needs: project vs standalone behavior, assignment defaults, priority naming, auth requirement, and the follow-up complete_task. It does not describe the created task's returned identifier, the only notable gap.

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 the schema already documents all six parameters. The description largely restates what the schema says ('assigns to you unless staff email', 'Priority uses the names in your account', standalone when project_id empty) with no syntax or format detail added, so the baseline 3 applies.

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 ('Adds a task to a project, or a standalone task when project_id is empty') and distinguishes the project vs standalone cases. It also names the lifecycle sibling complete_task, letting an agent tell it apart from list_tasks/complete_task without opening a schema.

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?

Provides context on defaults ('assigned to you unless you give a staff email', 'Priority uses the names in your account') but never states explicitly when to prefer this tool over siblings or any preconditions/exclusions for use. Usage is implied rather than spelled out.

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