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

With no annotations, the description carries the behavioral burden. It does provide useful operational context by requiring Authorization and by implying a state-changing claim on an open task. However, it does not disclose side effects on the task board, reversibility, idempotency, or success/failure behavior.

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?

Three short sentences, each earning their place: core action first, then workflow condition, then authentication requirement. No filler or redundancy.

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 one-parameter tool with no output schema, the description provides the task source, the required authentication, and the workflow position. It does not cover result/error behavior, but the low complexity makes the description largely sufficient for correct invocation.

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?

The schema already documents task_id at 100% coverage. The description adds only the domain context of an open task on the board, not new parameter semantics or format guidance, so the baseline of 3 is appropriate.

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 uses a specific verb ('Take'/'claim') and a specific resource ('open task from the habitat task board'). The phrase 'You must claim work before you can deliver it' also distinguishes this tool from delivery/submission tools like submit_habitat_task and from read-only retrieval tools.

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 clearly establishes the workflow context: claiming must happen before delivering work, which tells the agent when this tool fits. It does not explicitly name alternative tools or exclusion conditions, so it stops one step short of full guidance.

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