Update Work Order Contract Subcontractor SOV Status

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

Annotations indicate non-readonly, non-destructive, non-idempotent, and open-world. The description adds that the tool updates commitments and returns the modified object, and provides the API endpoint path. However, it does not disclose permission requirements, rate limits, or potential side effects such as cascading updates. The behavioral context is adequate but not exhaustive.

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 front-loaded with the core purpose and includes essential details (required params, API info) in a few sentences. It avoids unnecessary fluff, though the sentence about 'only the supplied fields are changed' is somewhat redundant given PATCH semantics. Overall, it is appropriately concise and structured.

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 moderate complexity (3 parameters, no output schema, minimal annotations), the description provides the API endpoint and states the return type ('modified object'). However, it lacks details on the returned object structure, error conditions, or integration implications. The description is sufficient for a simple update but incomplete for an agent to fully understand outcomes without additional context.

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?

The input schema has 100% coverage with descriptions for all three parameters. The description reiterates the required parameters and mentions status options but adds no new meaning beyond the schema. The schema already explains that status can be changed only under certain conditions (no requisitions, etc.), which the description partially repeats with a truncated sentence. Thus, the description adds minimal value over 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 verb (Update) and the resource (Subcontractor SOV status of a Work Order Contract). It distinguishes from siblings by specifying the contract type ('Work Order Contract') and naming similar sibling tools like 'update_purchase_order_contract_subcontractor_sov_status'. The purpose is specific and unambiguous.

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 explains that this tool updates existing commitments and lists required parameters, but it does not provide guidance on when to use this tool versus alternatives (e.g., updating other contract types or statuses). There is no mention of preconditions, when not to use, or fallback options. Usage context is implied but not explicit.

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