mureo_batch_end

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

With no annotations, the description fully discloses the key behavioral trait: 'Closing is FINAL: no later entry can join, so the member count stays true.' It also explains the return value and the refused condition, providing transparency beyond what structured data alone would offer.

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 compact and front-loaded. Four sentences each add distinct value: action/outcome, user guidance, finality warning, and precondition. No waste.

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 tool is simple (one optional parameter, no output schema), and the description adequately explains the return value, finality, and refusal condition. It provides enough context for an agent to invoke it correctly without needing extra documentation.

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 tool description adds no additional parameter meaning beyond what the schema already provides for the optional 'path' parameter. It does not describe the parameter or its constraints, but that is already covered in 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: 'Close the open batch' and specifies the outcome: 'return its exact membership: the action_log indices it collected and the platforms they span.' This distinguishes it from siblings like mureo_batch_begin and mureo_batch_status, which handle starting or checking status.

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?

The description gives clear context for when to use the tool: after collecting changes and wanting to finalize the batch. It also notes a when-not condition: 'Refused if no batch is open.' However, it does not explicitly mention alternatives, relying on sibling names to convey their roles.

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