brain_task_claim

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It discloses atomicity but omits critical behaviors: what happens if the task is already claimed, TTL semantics, whether the claim is idempotent, and what state changes occur. For a coordination tool, these details are essential.

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?

A single, front-loaded sentence with no filler. It communicates the core action and purpose efficiently. However, the extreme brevity omits parameter and usage details, so while it is concise, it is not fully appropriate for the tool's complexity.

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 tool with three parameters, no annotations, and an output schema, the description is far too thin. It leaves the agent guessing about return values, failure modes, and interaction with sibling tools like brain_task_release. Only the atomic coordination context is provided.

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 0%, and the description names none of the three parameters. It does not explain the role of 'agent', the meaning of 'ttl_hours', or how 'task_id' is used. With zero compensation from the description, this is a fundamental gap.

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 a specific verb ('claim') and resource ('task'), and enhances it with 'atomically' and the purpose 'for parallel agent coordination.' It conveys the tool's function and is implicitly distinguishable from sibling brain_task_release, though it does not explicitly compare them.

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?

There is no guidance on when to use this tool versus alternatives. The phrase 'for parallel agent coordination' implies a scenario, but it does not state when not to use it, prerequisites, or mention brain_task_release as the counterpart. An agent must infer the appropriate context on its own.

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