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

No annotations are provided, so the description carries the full burden. It discloses the tool's behavior by specifying it retrieves current state and listing possible states, but does not mention permissions needed, rate limits, or response format. This is adequate for a read-only tool with zero parameters, but lacks depth in behavioral context.

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, efficient sentence that front-loads the core purpose ('Get current OpenThread network state') and adds necessary detail (list of states) without any waste. Every word earns its place, 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 tool's low complexity (0 parameters, no output schema, no annotations), the description is complete enough for basic usage. It explains what the tool does and the possible return states, but could benefit from mentioning response format or error handling. However, for a simple state-retrieval tool, this is largely sufficient.

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 tool has 0 parameters with 100% schema description coverage, so the baseline is high. The description adds no parameter information, which is acceptable since there are no parameters to document. It compensates by clarifying the output semantics (possible states), aligning with the lack of parameters.

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 specific action ('Get current OpenThread network state') and resource ('OpenThread network'), distinguishing it from siblings like 'openwrt_thread_get_info' or 'openwrt_thread_get_dataset' by focusing on state retrieval. It explicitly lists the possible states (disabled, detached, child, router, leader), making the purpose unambiguous and distinct.

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 usage for retrieving network state, but does not explicitly state when to use it versus alternatives like 'openwrt_thread_get_info' or 'openwrt_thread_get_dataset'. It provides clear context for state checking, but lacks explicit exclusions or named alternatives, missing full guidance on sibling differentiation.

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