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

Annotations already indicate a non-read-only, non-destructive operation, and the description adds that the operation creates a task scoped to a project. It does not mention return behavior, permissions, failure outcomes, or task state, so it stops short of full transparency.

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, front-loaded sentences deliver the main action, project scope, and the two non-obvious parameters without filler. Every phrase earns its place.

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 straightforward create call with an output schema and annotations, the description plus input schema is sufficient to invoke it correctly: required project_id and title, optional priority and body. Minor gaps are explicit alternative routing and initial task state, but these are not required to make the call.

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?

With 0% schema description coverage, the description compensates by documenting priority's allowed values and default, and by explaining that body is markdown for goals, notes, and constraints. It also clarifies project_id's role through 'inside a project'; title is self-evident from its name.

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 states a specific action and resource: 'Create a task inside a project.' This clearly separates it from create_project/create_skill by resource and from update_task/update_task_state/delete_task by operation.

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?

No guidance is given about when to use create_task versus update_task or update_task_state. The description only states the action, leaving the agent to infer routing from sibling tool names.

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