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

With no annotations provided, the description carries full burden and adds significant behavioral context beyond the schema. It discloses critical constraints: dashboard interface usage, filePath-only parameter for requests (no content), deletion restrictions, and workflow dependencies ('Wait for user to review and approve before continuing'). However, it doesn't mention error handling, rate limits, or authentication requirements.

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 appropriately sized and well-structured with clear sections. The first sentence states the purpose, followed by usage instructions and critical warnings. Every sentence adds value, though the 'CRITICAL' section could be more concise by integrating with the action descriptions.

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 tool's complexity (8 parameters, multiple operations) and lack of annotations/output schema, the description provides substantial context about usage patterns, constraints, and workflow integration. It covers the main behavioral aspects but doesn't address potential edge cases, error responses, or the format of status results.

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 baseline is 3. The description adds some value by clarifying action-specific parameter requirements (e.g., 'Only provide filePath parameter for requests', 'approvalId required for status and delete', 'title required for request'), but doesn't provide additional semantic context beyond what's already documented in the schema descriptions.

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 the tool's purpose: 'Manage approval requests through the dashboard interface' and lists specific operations (request, check status, delete). It distinguishes from siblings by focusing on approval management rather than logging, spec status, or workflow guidance. However, it doesn't explicitly contrast with each sibling tool's specific domain.

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 provides explicit usage guidance: 'Use this tool to request, check status, or delete approval requests' with clear action-specific rules. It specifies when to use each action (e.g., 'request' after creating documents, 'delete' for completed/rejected/needs-revision requests) and includes critical exclusions ('cannot delete pending requests', 'Never include document content').

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