Update Purchase Order Contract Subcontractor SOV Status

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

Annotations indicate write (readOnlyHint=false) and possible side effects (openWorldHint=true). The description adds that only supplied fields are changed and returns the modified object, which is helpful. However, it does not mention permissions, reversibility, or constraints like the contract having no requisitions (hinted in schema but not in description). Given open world hint, more context is needed.

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 paragraph that front-loads purpose, then gives usage, then API reference. Every sentence adds value; no redundant fluff. It is appropriately sized for the tool's simplicity.

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 3 parameters with full schema coverage and annotations, the description covers the core functionality and API endpoint. However, it lacks context on return value format (no output schema) and domain-specific prerequisites (e.g., contract existence, user permissions). Adequate but not comprehensive.

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 lists the three required parameters but adds no new meaning beyond the schema. It states 'only the supplied fields are changed' which describes behavior, not parameter semantics.

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 it updates the Subcontractor SOV status of a specific Purchase Order Contract. It identifies the resource and action with the verb 'Update'. However, it does not explicitly distinguish this tool from similar ones like 'update_work_order_contract_subcontractor_sov_status', relying on the name for differentiation.

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 directs to 'Use this to update an existing Commitments' and lists required parameters. It implies the tool is for updating, but lacks explicit guidance on when to use vs. alternatives, prerequisites, or conditions when it should not be used.

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