create_task

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

No annotations are provided, so the description must disclose behavioral traits. It mentions optional contact linking but fails to specify whether the tool is idempotent, what side effects occur, or what the response contains (e.g., no mention of returning the created task ID). This is insufficient for a mutation tool.

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 extremely concise with two sentences that capture the core action and a key parameter relationship. No unnecessary words or repetition.

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 complexity (6 parameters, no output schema, no annotations), the description is minimal. It misses important details like return value, defaults (priority default is in schema but not description), and behavioral guarantees. However, the sibling tools provide some context for task management workflows.

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 67%, so the schema already describes most parameters (title, dueDate, priority, contactId). The description adds value by hinting that contactId should come from find_contacts, but otherwise provides no additional semantics beyond the schema.

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 'Create a task / to-do' with a specific verb and resource. It distinguishes this tool from siblings like update_task and list_tasks by focusing on creation.

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 for creating tasks but does not explicitly state when to use alternatives (e.g., update_task for modifications, complete_task for completion). The hint about contactId from find_contacts provides some guidance, but overall context is lacking.

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