Close Launch

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

Annotations already indicate destructiveHint=true (mutation) and idempotentHint=true (safe to retry). The description adds that it returns updated launch details, but does not disclose side effects on associated data or prerequisites. With annotations covering key behaviors, the description provides minimal additional context.

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 a single sentence of 7 words, extremely concise. Every word is functional, though the minimalism omits some potentially useful context. It is appropriate for a simple tool but not excessively verbose.

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?

Given the low complexity of the tool and the presence of annotations covering destructiveness and idempotency, the description covers the basic action and return value. However, it lacks details about error conditions, prerequisites, or the relationship to reopen_launch, which would enhance 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%, with clear descriptions for all four parameters (launch_id required, others optional). The description adds no further semantic meaning beyond what the schema provides, so baseline 3 applies.

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') and the resource ('launch'), and it specifies that the tool returns updated launch details. This distinguishes it from sibling tools like delete_launch (different action) and reopen_launch (opposite action), though the exact meaning of 'close' vs. 'delete' is not explicitly clarified.

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 provides no guidance on when to use this tool versus alternatives such as delete_launch or reopen_launch. There is no explicit when-to-use or when-not-to-use context, leaving the agent to infer based solely on the tool name.

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