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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, and openWorldHint=false. The description adds useful behavioral context: it creates no record or approval and returns review/direct requirements plus reasons, though it does not discuss permissions, audit logging, or rate limits.

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 short and front-loads the main usage condition, but it repeats the point that the tool creates no record or approval and restates the checking action in the second sentence, adding some redundancy.

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?

It tells the agent what the tool returns, which matters because there is no output schema, but with two required parameters and 0% schema description coverage it does not fully explain the kind enum or the payload object structure.

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 0%, so the description must carry parameter meaning. It partially explains that payload represents the "exact proposed fields" and that kind is the record-change type, but it does not explain the allowed kind values or the expected payload properties, leaving substantial ambiguity for a nested object parameter.

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 specific verb and resource: checking exact proposed fields against current security rules before confirming a record change. It also clarifies the outcome (review/direct requirements and reasons) and distinguishes the tool from record creation by saying it creates no record or approval.

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 gives a clear use condition: "Use this when checking whether exact proposed fields require review or may be applied directly." The "creates no record or approval" line implies this is not a drafting or creation tool, but it does not explicitly name sibling alternatives such as the draft_* tools.

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