woo_update_coupon

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

No annotations provided. Description simply says 'Update a coupon' with no disclosure of behavioral traits such as idempotency, side effects, or required permissions.

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 (3 words), but at the expense of necessary detail for a tool with 13 parameters. Minimal waste but insufficient information.

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?

Severely incomplete for the complexity. No output schema, no annotations, no description of update behavior or constraints. A 13-parameter tool needs far more 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?

Schema has 13 parameters with only 8% description coverage (only 'id' has a description). The tool description adds no parameter meanings, failing to compensate for low coverage.

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?

Description clearly states verb 'Update' and resource 'coupon', distinguishing it from siblings like 'woo_create_coupon' and 'woo_get_coupon'.

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 like 'woo_create_coupon' or other update tools. Lacks context for proper selection.

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