generate_cache_config

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

With no annotations, the description carries the burden of disclosing behavior. It describes the output content (revalidating HTML, caching assets as immutable), giving some transparency about what the generated config will do. However, it does not mention whether the tool writes files, returns a string, or has side effects on the target host. This is a partial disclosure but not comprehensive.

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, dense sentence that conveys the core purpose and key behavior without any redundant words. It is appropriately front-loaded and earns every word, making it highly concise and well-structured.

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 lack of annotations, no output schema, and an undocumented nested 'options' parameter, the description is insufficiently complete. It does not explain what the tool returns, how to use options, or any edge cases. For a tool generating configuration, the user needs to know the output format and how to customize behavior via options, both of which are absent.

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?

The schema description coverage is 0%, so the description must compensate for parameter documentation. It does indirectly reference the 'target' enum by naming the hosts, but it provides no explanation of the 'options' object or its possible properties. The description adds minimal value beyond the schema for the 'target' and none for 'options'.

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 generates cache-header configuration for a specific set of hosts (netlify, vercel, nginx) and specifies the caching rules (revalidate HTML, cache content-hashed assets as immutable for a year). This is a specific verb+resource action, and it distinguishes itself from sibling tools that handle other aspects like head tags, JSON-LD, sitemaps, and robots.

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 the tool is used when generating cache headers for these hosts, but it does not explicitly state when to use it versus alternatives, nor does it provide any exclusions or prerequisites. The scope is clear from the description, but there is no direct guidance on selection among nearby tools.

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