nginx_optimize

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

With no annotations provided, the description carries the full burden of behavioral disclosure, and it does little: it never says whether the tool returns an optimized config, writes to a file, or calls a remote service. It also doesn't explain why api_key is needed for an optimization operation, and '(Pro)' hints at entitlements without explaining what happens if the agent lacks them.

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 ten-word sentence that is front-loaded with the action verb and contains zero filler. Every word contributes to meaning, and the scope qualifier 'for performance and security' is efficiently bundled.

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?

The tool has 3 parameters, no output schema, and no annotations, so the description must carry the completeness burden. It fails to state what the agent receives in return, why the api_key parameter exists, or what the '(Pro)' designation means operationally. For a tool that appears to be a gated remote operation, this is a significant gap.

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%, so the baseline is 3 and the schema already documents all three parameters. The tool description adds no meaningful parameter detail beyond what the schema provides, though 'performance and security' loosely echoes the optimization_target enum values.

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 states a specific verb ('Optimize'), a clear resource ('Nginx configuration'), and the scope ('performance and security'). The verb contrasts with the sibling generate tools (nginx_generate_proxy, nginx_generate_ssl), making the tool's job distinct even without naming them. The '(Pro)' suffix adds a small but useful signal about tiering.

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?

No when-to-use guidance, no exclusions, and no mention of alternatives. The verb 'Optimize' weakly implies the agent already has an existing config to improve, but nothing explicitly routes the agent to this tool over nginx_generate_proxy/nginx_generate_ssl or clarifies prerequisites such as the api_key.

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