create_task_tool

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

No annotations are provided, so the description shoulders the full burden. It discloses that the tool creates a checkbox task, inserts it at a specified location, creates the file if missing, and formats metadata with emoji syntax. The return value is also described. No contradictions are present.

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 well-structured, starting with a clear purpose statement, followed by details on metadata formatting, a 'When to use' list, and a description of the return value. It is concise (about 15 lines) with no superfluous content; every sentence 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?

Given 11 parameters (2 required), no output schema, and no annotations, the description covers the most crucial aspects: creation behavior, insertion location, file creation, metadata formatting, and return format. It could be slightly more complete by mentioning error handling or limitations, but it is generally sufficient.

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 high (91%), so the baseline is 3. The description adds valuable context beyond the schema, such as explaining the emoji syntax for priority, dates, and recurrence, and the insert_at options. This enriches understanding of how parameters affect the output.

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 'Create a new task with Tasks plugin metadata (filesystem-native, offline).' It clearly specifies the verb (Create), resource (task), and context (Tasks plugin). This distinguishes it from sibling tools like toggle_task_status_tool or update_task_metadata_tool, which handle existing tasks.

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?

Includes a 'When to use:' section listing four concrete scenarios (e.g., 'Adding tasks to project notes', 'Creating recurring task templates'). This provides clear context for when to invoke this tool, though it does not explicitly state when not to use it.

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