capcut_create_video_bridge

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

There are no annotations, so the description must disclose behavior itself. It clearly states that it creates a draft, separates audio, and imports subtitles, which are valuable behavioral details. However, it does not disclose prerequisites (e.g., whether CapCut must already be open), handling of existing projects, side effects, or failure behavior, leaving notable transparency gaps for a no-annotation tool.

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?

The description is a single dense sentence with three clearly related behavioral clauses and little waste. It is front-loaded with the domain name and outcome. The parentheticals '(Remotion/WebGL)' and 'Direct Video Track Bridge' add mild jargon, but overall the description is appropriately compact.

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?

For a six-parameter orchestration tool with no annotations and no output schema, the description covers the main workflow but leaves practical questions unanswered, such as whether the CapCut app must be running, whether an existing project with the same name is overwritten, and what result or artifact the agent can expect. It is adequate but not complete enough for a complex tool.

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 100%, so the schema already documents all six parameters. The description adds framing by linking the video_plate_path to a 60 FPS master plate and subtitles_srt_path to editable subtitles, but it does not provide deeper per-parameter meaning. A baseline 3 is appropriate because the schema carries the load without contradiction.

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 names a specific verb and resource: it 'creates a CapCut draft around a pre-rendered master video plate,' 'separates multi-track audio,' and 'auto-imports subtitles.' This clearly distinguishes it from granular siblings like capcut_create_project, capcut_add_video_clip, and capcut_add_subtitles by framing it as an orchestrator. The 'Direct Video Track Bridge' label is somewhat niche, but the action and outcome are explicit.

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 conveys a clear use context: use this when you already have a pre-rendered 60 FPS master video plate and need to wrap it into a CapCut draft with separated audio and editable subtitles. It does not explicitly name alternatives or state when not to use it, so it stops short of a 5, but the context is strong enough to guide selection.

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