GET an LCU endpoint

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 return shape and states 'Always allowed', giving a safety hint. However, it does not describe error behavior, rate limits, or consequences of invalid paths. For a simple GET, this is partial coverage.

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?

Two sentences with no filler. The core action and return format are front-loaded, and the pointer to lol_endpoints is useful. Very efficient.

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 single-parameter GET tool with no output schema, the description covers the essential aspects: what it does, what it returns, and how to find valid inputs (via lol_endpoints). It could mention error handling, but the delegation to lol_endpoints mitigates the need. Overall reasonably complete.

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 0%, and the description does not explain the 'path' parameter in detail beyond 'any LCU path'. It points to lol_endpoints for discovery, which compensates somewhat, but the description itself adds little semantic detail about the parameter's format or valid 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?

States a specific verb (GET), resource (any LCU path), and return shape ({ status, body }). Names a sibling (lol_endpoints) for discovery, which also helps differentiate its scope. The 'Always allowed' adds a constraint.

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?

Gives some guidance: use lol_endpoints to discover paths, and 'Always allowed' implies no restrictions. However, it does not explicitly contrast with alternative tools like lol_request (likely for non-GET methods) or specify when not to use this tool. The guidance is implicit rather than explicit.

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