approve_request

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

Annotations already indicate write operation (readOnlyHint=false) and idempotency (idempotentHint=true). Description adds the WRITE_ENABLED prerequisite, which is useful. However, it does not disclose side effects (e.g., workflow triggers, notifications) or post-approval behavior, leaving room for improvement.

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?

Single sentence with critical prerequisite in parentheses. No superfluous words. Front-loaded with verb and resource. Excellent conciseness.

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?

With no output schema, the description should explain what the tool returns (e.g., success status, updated record) and any side effects (e.g., workflow triggers). It does not. For an approval tool with moderate complexity, this is a significant gap.

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 covers 100% of parameters with descriptions. The description does not add additional semantic information about the parameters beyond what the schema provides. Baseline score of 3 is 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?

Description specifies the verb 'Approve' and the resource 'pending approval request', clearly distinguishing from sibling tools like reject_request and list_approvals. It includes a prerequisite, making the purpose immediately understandable.

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?

The description explicitly states a required condition (WRITE_ENABLED=true). While it does not provide explicit when-to-use vs when-not-to-use, the verb and sibling context implicitly guide usage: this tool is for approving, not canceling or rejecting. Missing explicit exclusions, but clear overall.

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