Create a track

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

The description discloses idempotency key deduplication behavior (24h window) and notes that without a key each call is a new operation. Annotations provide no behavioral hints, so the description carries the burden; it adds useful context about mutation and deduplication.

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, no redundancy. First sentence states purpose, second provides critical parameter details and idempotency guidance. Every sentence is necessary and front-loaded.

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 the complexity (creation tool with many required fields, nested object, no output schema), the description covers purpose and key parameters but does not mention return values, success/failure behavior, or any side effects beyond idempotency. Slightly incomplete.

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 100% (both parameters documented). The description adds meaning by listing required fields, specifying the ISO format for recording_country, and explaining idempotency_key purpose and behavior – going beyond the schema.

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 states 'Create a track on a release' – a specific verb and resource. It clearly distinguishes from siblings like create_release, update_track, and delete_track by specifying the action of creation.

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 explains when to use (to create a track) and provides guidance on idempotency key usage for retries. However, it does not explicitly mention when not to use or list alternative tools for modification vs creation.

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