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

The description adds substantial behavioral context beyond the annotations: it explains the effect of approving (one-time repeat) and rejecting (permanent hold), states who can decide, notes audit logging, and details required credentials and workspace state. These details are not present in the annotations and directly aid safe invocation.

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 and every sentence conveys important information, but it is somewhat dense and could be tightened without losing clarity.

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?

For a destructive mutation tool with no output schema, the description covers all essential aspects: effect of the operation, authorization requirements, audit logging, credential needs, and workspace claim prerequisites. Nothing critical is missing.

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 description coverage is 100%, so the input schema already documents each parameter. The description adds no additional parameter-level meaning, leaving the baseline of 3 appropriate.

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 states a clear verb (approve or reject) and resource (an action held for approval), and explains the effect of each decision. However, it does not explicitly differentiate from similar siblings like approve_commerce_proposal or approve_payout_run, which could lead to confusion.

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?

It provides clear context for who may call it (workspace owner, not an agent) and prerequisites (Last Price credential with commerce proposal approve scope, claimed workspace), but it does not name alternative tools or explicitly state when to use this vs. specialized approval tools.

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