create_groove

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

Annotations only indicate it's not read-only and not destructive, but the description adds useful context: it mentions the dry-run/confirmation token flow implicitly via schema and states that deletion is not exposed. It does not explicitly mention that creation is not directly executed (only planned), but the schema's dryRun/confirmationToken parameters imply a two-phase process. The description does not contradict annotations, so no contradiction.

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, front-loaded with the main action and optional name, then directs to set_groove and clarifies deletion. No fluff, every sentence earns its place.

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?

With no output schema, the description could be expected to explain what the plan/confirmation flow returns, but it doesn't. However, the schema documents the parameters sufficiently. It explicitly mentions the two-phase constraint (dryRun/confirmationToken) through the schema, and the fact that deletion is not available fills a contextual gap. Overall, adequate but could benefit from a note on the return value of a successful plan.

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 100%, so all 5 parameters are documented. The description adds the notion of 'base grid' and 'amounts' which relate to the groove's properties but doesn't detail them in the description. It doesn't elaborate on the dryRun/confirmationToken flow beyond what the schema says. Baseline 3 is appropriate.

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 clearly states it creates a groove with an optional name, and mentions adjusting afterward with set_groove. This distinguishes it from related operations like set_groove, though it could be more specific about what 'create' entails (e.g., whether it adds to the pool or just plans).

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?

Explicitly says to use set_groove for adjustments and mentions that deletion is not exposed. This gives clear guidance on what this tool is for and what it is not for, effectively routing the agent to the correct sibling.

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