Set track storefront

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

The most important behavior—whole-storefront replacement with clearing of omitted optional fields—is stated upfront, warning the agent to send all values that should remain. This adds meaningful behavioral nuance beyond the annotations' idempotent and read/write hints.

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 compact sentences front-load the purpose and immediately warn about replacement semantics. No filler or repetition of schema details.

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 an 8-parameter mutation with no output schema, the description covers the core invocation context: target ownership, create-or-replace behavior, and the data-loss warning. It leaves response/error details to runtime feedback, but nothing essential for correct invocation is missing when combined with the schema.

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 high at 75%, so parameter details are largely already available. The description adds the crucial semantic that optional omitted parameters are cleared, which affects how every optional parameter should be considered when building arguments.

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 names a specific action ('Create or replace'), the target resource ('storefront (buy / link module)'), and its scope ('on a track owned by the logged-in user'). This is easily distinguishable from siblings like update_track or set_like.

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?

It is clear that the tool is for setting/replacing the buy/link module on the caller's own track and that every preserved field must be sent. It does not explicitly name alternative tools or state when not to use it, but the usage context is strong.

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