create_lane

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

With no annotations, the description carries the full burden for a mutation tool. It does not disclose whether lane names must be unique, what happens if a lane with that name already exists, whether the operation is reversible, whether permissions are required, or what is returned on success.

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?

One short sentence, front-loaded with the verb and resource, with the examples doing efficient work. No filler.

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 write operation with zero annotation coverage and no output schema, the definition is thin: an agent cannot tell from it what a successful call returns, how duplicates are handled, or where the new lane appears in relation to list_lanes. The name semantics are the only thing fully covered.

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%, so the description must compensate for the single 'name' parameter. The examples ('Hero shots', 'Final cut') usefully convey that names are human-readable display labels rather than IDs, but they add no detail on length limits or character constraints, leaving the schema's minLength/maxLength undocumented.

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 and resource ('Create a custom lane') and clarifies the otherwise opaque concept of a 'lane' with concrete examples ('Hero shots', 'Final cut'). It does not explicitly name or contrast with the siblings list_lanes and move_to_lane, so it falls short of a 5.

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 examples hint at the domain but the description never says when to create a lane versus using list_lanes to inspect existing ones or move_to_lane to assign assets. No prerequisites or exclusions are given.

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