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

Annotations already cover read-only, idempotent, non-destructive behavior. The description adds tenant scoping and explains the resource concept, but doesn't disclose pagination behavior or any operational details. Acceptable given annotation coverage, but minimal.

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?

Two sentences, front-loaded with the main purpose. The second sentence about endpoint definition is informative but not essential for invocation; still concise and without 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?

With an output schema present and parameter descriptions complete, the description is mostly sufficient. It doesn't explicitly mention pagination defaults or filtering behavior, but those are covered by the schema. Could benefit from a note on intended usage.

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 has 100% coverage for all three parameters (page_size, page_token, slug_prefix). The description adds no parameter-specific meaning, so it relies entirely on the schema, which meets the baseline.

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?

States a specific verb (list) and resource (dynamic endpoints) with tenant scope, and briefly defines what an endpoint is. This distinguishes it from sibling get_dynamic_endpoint and list_dynamic_endpoint_runs, though it doesn't explicitly contrast them.

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?

Provides no guidance on when to use this tool versus alternatives like get_dynamic_endpoint or list_dynamic_endpoint_runs. No conditions, exclusions, or context for selection are given.

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