diagnose_environment

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

With no annotations, the description carries the behavioral disclosure burden. It clearly labels the tool 'Read-only' and states the return type and fields ('EnvironmentReport with ready/java/jmeter/plugins fields'), giving agents confidence that this is a safe inspection. It does not cover potential error conditions, but for a zero-parameter read-only tool this is adequate.

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 two sentences with a front-loaded action phrase and a clean usage statement. Every sentence adds value: one identifies scope and safety, the other gives timing and return shape. No filler or redundancy.

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?

For a simple no-argument diagnostic tool with an output schema, the description provides the essential purpose, read-only safety, usage timing, and return structure. It is sufficient for an agent to select and invoke the tool correctly.

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?

There are zero parameters and schema coverage is 100%, so the baseline for parameter semantics is 4. The description needs to add no parameter-specific details, and it does not.

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 opens with 'Read-only environment diagnosis for Java, JMeter, plugins, and Docker,' which provides a specific verb and resource scope. It clearly distinguishes the tool from siblings like ensure_environment by emphasizing a non-mutating readiness check.

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?

'Use before planning work when you only need readiness details' gives explicit contextual timing and conditions for use. It does not explicitly name alternatives or exclusions, but the phrase 'when you only need readiness details' implies other tools handle additional needs.

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