cors_analyze_config

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

No annotations are provided, so the description must carry the full burden of disclosure. 'Analyze' implies a read-only operation, but the description does not state whether the tool modifies anything, what prerequisites exist (e.g., existing CORS configuration), what it inspects (files, API endpoints, cloud resources), or what it returns. This leaves significant behavioral uncertainty for such a minimally specified tool.

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 short sentence with no filler or irrelevant detail. It front-loads the core intent. However, it is so terse that it sacrifices useful information; it is concise in form but not in content depth.

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 annotations, no output schema, two parameters where one is undocumented, and a one-line description, this definition is incomplete for safe tool invocation. An agent does not know what the analysis result will be, whether it needs an api_key for certain directory types, what failures could occur, or how this relates to the many CORS-related siblings. The minimal phrasing leaves too many operational gaps.

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 coverage is only 50%: 'directory' is documented as 'Project directory', but 'api_key' has no schema description and the tool description adds nothing about either parameter. The agent cannot tell whether api_key is required for remote analysis, authentication, or something else, nor how directory should be formatted. The description does not compensate for the schema gap.

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 names a concrete verb and resource ('Analyze CORS configuration'), so an agent knows the general intent and can distinguish it from sibling generation tools like cors_generate_middleware. However, it is vague about what specific aspects of CORS configuration are analyzed, what the output looks like, or what 'configuration' refers to (source code? deployment manifests? headers?). It reads as an expanded version of the tool name rather than a substantive definition.

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?

There is no guidance on when to use this tool versus alternatives. The sibling list includes cors_generate_middleware, cors_generate_policy, and s3_setup_cors, but the description never explains whether this tool is for auditing existing configs, validating a new setup, or comparing policy across services. The agent is left to infer all usage context.

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