claim_next_batch

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

No annotations are provided, so the description carries full burden. It discloses that the batch is locked for a configurable lease (30s default) and that failure to provide data releases the batch for others. This explains critical side effects.

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 three sentences, front-loaded with the core purpose. Each sentence adds essential information: purpose, ordering dependency, and lease behavior. No superfluous words.

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?

The description covers the claim operation, lease, and workflow dependency. However, it does not mention the return value (likely the batch data) or error conditions (e.g., no pending batch). With no output schema, this omission slightly reduces completeness.

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%; both parameters (runId, leaseMs) are already described in the schema with identical semantics. The description reinforces the leaseMs default but adds no new information 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: 'Claim the next pending mock batch for processing.' This distinguishes it from sibling tools like get_batch (reading) and release_batch (releasing). The verb 'claim' and resource 'mock batch' are specific.

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 says 'You MUST call this before provide_batch_mock_data', providing a clear ordering requirement. It also explains the lease mechanism and timeout behavior, guiding when to use this tool in the workflow.

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