Razor All Tracks

razor_all_tracks

Split every video and audio clip at the playhead or a set time across all tracks, with optional filtering by track type. Use it to cut multiple timeline layers at once.

Instructions

Razor (split) all clips at the playhead position across all tracks, or at a specific time.

TDQS

A3.6/5.0
Behavior3/5

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

Annotations already declare the safety profile (readOnlyHint=false, destructiveHint=false, idempotentHint=false). The description adds the default-targeting behavior (playhead if no time given, all tracks by default), which is useful, but says nothing about undo, resulting edit points, or any permission/state requirements for a mutation.

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

Conciseness5/5

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

A single tight sentence with the core operation front-loaded and the optional time argument trailing as a clause. No filler or redundancy.

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

Completeness4/5

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

For a two-parameter tool with a full schema and an output schema, the description covers what the tool does and how targeting defaults work. The main omission is guidance on how this interacts with the many adjacent edit operations (e.g., split_clip), which is minor.

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

Parameters3/5

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

Schema description coverage is 100%, so both parameters (track_type, time_seconds) are already fully documented, including the playhead default and enum values. The description restates the same default semantics without adding format or edge-case detail, so baseline 3 applies.

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

Purpose4/5

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

States a specific verb ('Razor (split)'), the resource ('all clips'), and the scope ('across all tracks'), making the operation clear. It implicitly distinguishes itself from the single-clip sibling split_clip via the 'all tracks' scope, but never names that sibling explicitly.

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

Usage Guidelines3/5

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

Gives one concrete usage condition ('at the playhead position ... or at a specific time'), which tells the agent the two ways to invoke it, but provides no when-not guidance, prerequisites, or explicit routing away from similar tools such as split_clip or ripple_delete.

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