C2.9/5.0
Behavior2/5

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

With no annotations provided, the description carries the full behavioral burden, but it discloses nothing beyond the action itself. It does not say whether the operation permanently moves clip boundaries (destructive), whether it affects all transitions or just the nearest, what happens if no beat is detected, or what is returned. For a mutation-style tool, this is a significant gap.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

A single nine-word sentence with zero filler, and the core action is front-loaded. It is genuinely concise rather than bloated, though the brevity veers toward under-specification given the missing parameter and behavior context.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a tool with no annotations, no output schema, and two unexplained parameters, this definition is too sparse. An agent needs to know what 'snap' does to the timeline, how the two track IDs relate, and the expected result. The description leaves the call's behavior materially underspecified.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0% and the description adds no parameter meaning. The term 'audio track' hints at audio_track_id's role, but track_id is entirely unexplained, leaving the agent to guess which track holds the transitions. Neither parameter's type, role, or relationship is clarified.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses a specific verb ('snap') and identifies both the object being modified ('clip transitions') and the target ('nearest beat in the audio track'). It is the only beat-synchronization tool among the 37 siblings, so an agent can distinguish it without opening the schema.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No usage context is provided. It does not name alternatives (e.g., trim, move, ripple_delete) or state when this tool is preferred over manual nudging. It also fails to mention prerequisites such as requiring a pre-existing audio track with detectable beats or that transitions must already exist.

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