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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It mentions optional filtering and implies a list operation, but fails to describe key behaviors such as pagination handling (though parameters exist), rate limits, authentication requirements, or what the output format looks like. For a list tool with zero annotation coverage, this leaves significant gaps in understanding how the tool behaves.

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 a single, efficient sentence that front-loads the core action ('List all guardrails') and includes key details (organization scope and filtering options) without any wasted words. It's appropriately sized for its purpose.

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 of a list operation with 4 parameters, no annotations, and no output schema, the description is incomplete. It lacks details on behavioral aspects (e.g., pagination, rate limits), output format, and error handling, which are crucial for an agent to use the tool effectively in a real-world context.

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%, meaning all parameters are documented in the input schema. The description adds minimal value by mentioning 'optional filtering by workspace or organization,' which aligns with two parameters but doesn't provide additional semantics beyond what the schema already covers. This meets the baseline for high schema coverage.

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 verb ('List') and resource ('all guardrails in your Portkey organization'), making the purpose specific and understandable. However, it doesn't explicitly differentiate this tool from sibling tools like 'get_guardrail' (which retrieves a single guardrail) or other list tools, missing an opportunity for clear sibling distinction.

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 implies usage through the phrase 'with optional filtering by workspace or organization,' suggesting this tool is for listing guardrails with potential filters. However, it doesn't provide explicit guidance on when to use this tool versus alternatives (e.g., 'get_guardrail' for a single guardrail) or any prerequisites, leaving usage context partially implied.

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