write_setup

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

No annotations exist, so the description must fully disclose behavior. It does explain clamping/snapping when ranges exist and a warning otherwise. However, it does not clarify whether an existing setup with the same name is overwritten, nor what the return value is. This leaves notable gaps, so a score of 3 is appropriate.

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 front-loaded purpose sentence, followed by parameter explanations and a key behavioral note. Every sentence adds value, including the example and ranges behavior. It is nearly perfect but could be slightly tighter (e.g., merging parentheses).

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 no annotations and 0% schema coverage, the description covers the main functionality and an important edge case (ranges). However, it omits what the output schema contains, whether the tool can overwrite existing setups, and any prerequisites (e.g., valid car/track names). It is adequate but leaves several gaps for a tool with these signals.

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%, so the description must compensate. It explains values_json with a clear example and describes base_setup's purpose. However, the required parameters car, track, and name are not described, leaving their semantics implied. Partial compensation keeps this at a mid score.

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 uses the specific verb 'write' and identifies the resource as 'setup file'. It clearly states the purpose: creating a new setup the user can load from the in-game setup menu. This distinguishes it from siblings like read_setup (read) and list_setups (list), earning a top score.

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 creating or modifying a setup (via base_setup), but does not explicitly state when to use this tool versus alternatives. No exclusions or prerequisites are mentioned. The guidance is present only by implication, which is adequate but not strong.

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