create_task

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

No annotations are provided, so the description bears the full behavioral transparency burden. It clearly discloses that this is a WRITE operation, describes the immediate side effect (a new item appears in the task app), and states the return value, including the new id.

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 front-loaded with the WRITE callout, then a compact definition, use case, side effect, return value, and sibling routing. Every sentence earns its place and there is no filler.

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 6-parameter create tool with no annotations and no output schema, the description covers the purpose, the human-facing nature of the write, the immediate behavioral consequence, and a clear return guarantee. Schema covers parameters, so nothing an agent needs to call it correctly is missing.

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 baseline is 3. The description does not add much parameter-level semantics beyond the schema, though it does imply the item model and reinforces the main purpose of title. With all parameters already documented well in the schema, additional detail is unnecessary.

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 verb and resource: creates a new item (task/note) in the store. It clearly frames the tool as the agent-to-human write side of a two-way bus and names update_task as the alternative for modifying existing items, which distinguishes it from siblings.

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?

It explicitly tells the agent when to use this tool, to hand the human a note, action, or reminder, and explicitly tells it to use update_task instead when changing an existing item. This is direct routing guidance between competing write tools.

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