create_project_task_assignment

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

No annotations are provided, so the description carries the full burden. It discloses the basic effect (making task available for time tracking) but does not cover important behaviors: idempotency, error handling, authorization requirements, or what happens if the assignment already exists.

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?

The description is two sentences long with no wasted words. It is front-loaded with the core action and efficiently adds extra detail.

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?

Given the lack of annotations and output schema, the description adequately covers purpose and key parameters but omits behavioral details like idempotency, error scenarios, and prerequisites. It is sufficient for basic understanding but not fully complete.

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% with good descriptions for each parameter. The description adds context that the 'hourly_rate' and 'budget' are project-specific, but this adds only minor value beyond the schema descriptions.

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 clearly states the action ('Assign a task to a project'), the outcome ('making it available for time tracking'), and the additional capability ('Allows setting project-specific rates and budgets'). It distinguishes from siblings like 'create_task' (which creates a new task) and 'update_project_task_assignment' (modifies an existing one).

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?

The description implies usage when you need to link a task to a project for time tracking with optional custom rates/budgets, but it does not explicitly state when NOT to use it (e.g., if the task is already assigned) or mention alternatives like 'create_task' or 'update_project_task_assignment'.

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