C2.6/5.0

Behavior2/5

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

Annotations already declare readOnlyHint=false, destructiveHint=false, so the safety profile is covered structurally. The description adds almost nothing beyond that: no mention of duplicate-name behavior, validation failures, side effects on related sessions/logs, or what 'Deletes are not supported' is meant to warn against in a create operation.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Very short and front-loaded, which is good, but the second sentence is a non sequitur for a create tool and consumes half the available text without earning its place.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With seven parameters, a nested open-ended object, and low schema coverage, the description is far too thin. An output schema existing excuses explaining return values, but the input-side gaps (especially setupData contents and dataLogIds/influencedSessionId linkage) remain unaddressed.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is only 43% across seven parameters, including a free-form nested setupData object and undocumented vehicleId, setupName, dataLogIds, and influencedSessionId. The description provides no parameter meaning at all, so it fails to compensate for the coverage gap.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource ('Saves a new TuneWorks setup for a vehicle'), which is clearly distinguishable from update_setup and archive_setup. The scope of 'new' is stated explicitly. It stops short of differentiating itself by naming any sibling tool.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No indication of when to use this versus update_setup or archive_setup, no prerequisites (e.g., vehicle must already exist), and no guidance about duplicate setups. The only usage-adjacent statement, 'Deletes are not supported,' describes an unrelated capability rather than when to call this tool.

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