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

Annotations already note that the tool is idempotent and not read-only, but the description adds the side effect of emailing Jetblanc's desk and gives operational guidance for idempotencyKey reuse. This goes beyond the structured annotations without contradicting them.

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 tuned for purpose: core action, exclusion, and retry guidance. No wasted words and the key facts are front-loaded.

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 tool's complexity (nested request object, 4 params, no output schema), the description leaves out necessary workflow context: how this relates to sibling validations, what the response looks like, or whether any precondition must be met beyond an 'authorised' brief. It is adequate but not thorough.

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 coverage is 0%, so the description carries a heavy burden. It adds semantic value for idempotencyKey (retry behavior) and implies userApproved corresponds to 'authorised', but it says nothing about internalTest or the request object structure. This is partial compensation, not complete.

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 names a clear action ('save the authorised brief') and a side effect ('email Jetblanc's desk'), and explicitly distinguishes what it is not ('Not a flight booking'). This gives an agent an immediate, specific understanding of the tool's scope.

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 implies usage context ('authorised brief' and 'LIVE') but does not explicitly state when to prefer this tool over sibling tools like get_request_status or validate_trip_brief. The 'Not a flight booking' exclusion is present but low-value for differentiating from the actual siblings.

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