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

Annotations already provide readOnlyHint=true and openWorldHint=true, so the read-only nature is covered. The description adds that it returns a structured, audited deliverable and that inputs are validated server-side, but doesn't detail deliverable format, pagination, or any side effects beyond the annotations.

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 and front-loaded with the core purpose. The reference case adds useful context but could be considered extraneous, and the 'Gapup agent-payable' phrase is somewhat opaque. Overall, each sentence contributes to positioning the tool.

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 (8 parameters, nested objects, no output schema, low schema coverage), the description is incomplete. It doesn't explain what the deliverable contains, how to construct the input case, or how to interpret the output. The absence of an output schema makes the description insufficient for correct invocation.

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 only 13%, so the description must compensate but doesn't. It merely says 'send the documented case fields' and references example metrics (ARR, forecast accuracy, revenue leakage) that map loosely to schema properties, but it doesn't enumerate or explain the nested object structures or required fields.

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 identifies the tool as a RevOps architect providing C-suite CRO expertise and returning a structured, audited deliverable. It distinguishes from sibling architects by naming RevOps and CRO focus, though the exact action (e.g., 'design a RevOps plan') is implied rather than explicitly stated.

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 explicit guidance on when to use this tool versus alternatives. The reference case hints at revenue leakage and forecast inaccuracy as triggers, but there is no direct 'use when' or comparison to other strategist/architect tools like abm_architect or comp_plan_architect.

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