track_set_properties

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

With no annotations, description carries full burden. It adds valuable constraint information (gain range -36 to 36, pan range -1.0 to 1.0) not present in schema, but omits safety profile (destructive vs reversible), return behavior, or error handling.

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?

Efficient Args-list format with zero redundancy. Front-loaded purpose statement followed by dense parameter specifications. Slightly technical formatting but appropriately sized for the information density.

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 6 parameters with complex optional semantics (union types with null) and no output schema, description successfully documents all inputs. Minor gap regarding default behaviors or partial update semantics (setting only some properties).

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?

Perfect compensation for 0% schema coverage. Documents all 6 parameters with precise semantics: track indexing (0-based), gain units (dB), pan mapping (-1.0=left to 1.0=right), and boolean flags for mute/solo.

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?

States specific action ('Set properties') and target resource ('track by index'), but fails to distinguish from sibling tools like 'track_mute' or 'track_get_info' that handle specific single properties or read operations.

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?

Provides no guidance on when to use this multi-property setter versus single-purpose siblings like 'track_mute', nor does it mention prerequisites (e.g., track must exist) or error conditions.

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