get_chain_details

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

No annotations are provided, so the description carries full burden. It only mentions 'full details' and 'device list' without disclosing what other details are included, whether the operation is read-only, or any side effects. The existence of an output schema partially mitigates this, but the description itself lacks 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 clear sentence that immediately communicates the tool's purpose. It is appropriately sized for a simple retrieval tool, though it could benefit from a note about parameters.

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?

Despite having an output schema, the description is too sparse. It does not explain the three required parameters or provide any usage context. For a tool with 0% schema description coverage, this is insufficient for an agent to correctly invoke it.

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 coverage is 0% (no parameter descriptions in schema). The description does not explain what track_index, device_index, or chain_index represent, how to obtain their values, or any constraints. Agents would have no guidance on filling these required integers.

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?

Description clearly states it retrieves full details of a rack chain including its device list. This distinguishes it from siblings like 'list_chains' (which likely only lists chain indices) and 'get_chain_devices' (which might return only devices). The verb 'Get' and resource 'full details of a rack chain' are specific and unambiguous.

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 when full chain details are needed, but it does not explicitly state when to use this tool versus alternatives such as 'get_chain_devices' or 'list_chains'. No when-not or context exclusions are provided. The agent is left to infer from sibling names.

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