finalize_purchase_document

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

Description does not disclose binding nature or irreversibility beyond what is hinted in the schema's confirm parameter description. Without annotations, the description should emphasize that finalization is a critical action but fails to do so.

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?

Extremely concise (one sentence), but it omits critical behavioral context. Conciseness should not come at the expense of completeness.

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?

Despite having output schema, the description lacks essential context about the action's implications (e.g., irreversibility, confirmation requirement). For a binding operation, this is insufficient.

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 100%, so baseline is 3. The description adds no extra meaning to the parameters beyond what the schema provides. The confirm parameter's description in schema already states 'Must be true. Finalization is binding.'

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?

Clear verb and resource: 'Finalize a draft purchase document.' It specifies the action (finalize) and the object (draft purchase document), distinguishing it from siblings like finalize_sales_document.

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?

No guidance on when to use this tool versus alternatives. It does not mention prerequisites (e.g., document must be in draft status) or when not to use it (e.g., if already finalized).

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