verify_ros2_environment

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

No annotations are provided, so the description must fully disclose behavioral traits. It states the tool checks environment readiness and returns status, but lacks details on what happens if the environment is not ready (e.g., error vs. false return), whether the tool modifies anything, or any side effects. This leaves ambiguity for the agent.

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 concise, with a clear opening sentence and a bullet list of return values. It is front-loaded with purpose. Minor improvement could be trimming redundancy, but overall it is 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 tool has no parameters and an output schema exists, the description covers all necessary aspects: purpose, usage context, and return values. It is complete for an agent to understand when and how to invoke this tool.

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 input schema has no parameters, and schema coverage is 100%. The description does not need to add parameter meaning since there are none. It appropriately focuses on the tool's behavior rather than parameter documentation. Baseline for zero parameters is 4.

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 defines the tool's purpose: verifying the ROS2 environment setup. It mentions specific checks like ROS2 availability, version, and environment variables. This distinguishes it from sibling tools like check_autoware_status or health_check, which focus on different aspects.

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 provides context: users should have sourced their ROS2/Autoware environment before starting the server. It implies using this tool after server start to verify readiness. However, it does not specify when not to use it or list alternative tools.

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