update_automatic_discount_bxgy

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

With no annotations, the description must provide behavioral context. It only mentions 'Only provided fields are changed,' which implies a PATCH-like behavior, but lacks information on side effects, authorization requirements, error conditions, or whether the discount must be active.

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 concise at two sentences, but it sacrifices completeness for brevity. While it front-loads the core purpose, it omits necessary details, making it under-informative.

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 complexity (16 parameters, nested objects, no output schema, no annotations), the description is far from complete. It fails to explain return values, error handling, or parameter dependencies, leaving the agent with insufficient 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 coverage is only 13% (2 of 16 parameters have descriptions). The description adds no parameter details, leaving the agent to infer from names alone. For a tool with many parameters, this is insufficient.

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 an existing automatic BXGY discount, with the specific verb 'Update' and explicit resource. The phrase 'Only provided fields are changed' clarifies the partial update semantics, distinguishing it from create tools.

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 is provided on when to use this tool versus other update discount tools (e.g., update_automatic_discount_basic) or when not to use it. Prerequisites or alternatives are not mentioned.

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