Analyze HTTP cache policy

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

Annotations already declare readOnlyHint=true, idempotentHint=true, openWorldHint=true, and destructiveHint=false, so the safety profile is fully covered. The description's only additions are the 'one authorized response' constraint and the sensitive-path caching scope, which are mildly useful but say nothing about live-request behavior, rate limits, or what 'authorized' implies operationally.

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?

A single 20-word sentence with zero filler, and the analysis scope is front-loaded right after the verb. It packs five facets into one list, which is dense but not padded.

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?

An output schema exists, so return values need not be described, and annotations fully cover the safety profile; with only one parameter, the definition is nearly complete. The remaining gap is routing guidance against the many overlapping header/cookie/CORS analysis siblings, which the description does not address.

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 0% for the single required 'url' parameter, so the description must compensate. 'on one authorized response' hints that the URL targets a single HTTP response and that the caller must be authorized to test it, but there is no guidance on URL format, absolute vs. relative, or the 2048-char limit.

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 ('Assess') and a specific resource ('Cache-Control, Vary, validators, CDN signals, and sensitive-path caching'), which pins down the scope far better than the generic title 'Analyze HTTP cache policy'. It implicitly separates itself from broad siblings like headers_analysis by naming cache-specific facets, but it never names an alternative tool outright.

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 phrase 'on one authorized response' communicates the operating scope (single response, authorization required), which is real usage context. However, there is no explicit when-to-use guidance, no exclusions, and no pointer to the overlapping siblings such as headers_analysis or cookie_security_analysis, so the agent must infer when this is the right call.

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