prepare_track

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

It discloses key behavior beyond annotations, specifically idempotence (adds only what is missing, in order, at the end) and role fallback from track name. However, dry_run defaults to true yet the description never mentions dry-run semantics, which is important for whether a call actually mutates the chain.

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 dense sentences carry meaning without filler; the core behavior, role maps, role fallback, ordering, idempotence, and chain position are all included efficiently.

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?

The output schema exists, so return-value explanation is unnecessary. The description is sufficient for a domain-expert agent to understand the core operation, but lacks clarity on what track numbers refer to and whether dry_run actually prevents mutation, leaving real invocation gaps.

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. The description helpfully explains role semantics (read from track name unless given, unless explicitly provided), but track is unexplained as an integer identifier and dry_run behavior is left entirely to inference from its name/default value.

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?

Description states a concrete behavior with resource (track chain) and specific role-to-chain mappings, and explains role fallback logic. It is not a tautology and likely distinguishes prepare_track from vague siblings, though it does not explicitly name siblings.

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 when to use it: prepare a track by appending the standard role chain for kick, bass, master, with role inferred unless explicit. It gives no explicit when-to-use vs alternatives or when-not-to-use guidance, so usage context is implied rather than stated.

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