async-analyze

async-analyze is a skill for Claude Code from twelvelabs-io/twelve-labs-claude-code-plugin. It costs 73 tokens per session (2,096 once invoked), scanned A, original, MIT.

A background video-analysis tool that accepts a URL, local file, uploaded asset, or base64 data without requiring the video to be indexed first.

In plain words
What is it for?
Use it to analyse videos up to two hours, extract tagged segments, use reference images, request JSON-shaped results, or check and manage analysis tasks.
Why use it?
It handles longer videos and analyses that need time-based results, reference images, or structured JSON instead of waiting for an immediate answer.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

async-analyze scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Async Video Analysis

Asynchronously analyse a video using Pegasus 1.5 (default). Accepts a direct http(s) URL, a local file path (auto-uploaded as an asset), a previously uploaded asset ID, or base64 data — no prior indexing required. Handles videos up to 2 hours. Returns a task ID immediately; poll with get-analyse-task for the result.

When to Use This Skill

Use this skill when the user:

  • Provides a video URL or local file path they want analysed
  • Has a video over 1 hour long (sync analyze caps at 1 hour)
  • Wants time-based metadata extraction — structured per-segment output (e.g. "find every highlight and tag each one with description+importance")
  • Wants multimodal prompting with reference images (promptV2 + mediaSources)
  • Wants structured JSON output (jsonSchema)
  • Asks about a pending async analysis task ("is my analysis done?")
  • Asks to check, list, filter, or delete async analysis tasks

For short, prompt-only analysis of an already-indexed video, use sync-analyze instead — it returns inline.

Model Default

pegasus1.5 for everything. Only set pegasus1.2 when the user explicitly asks for legacy mode.

Instructions

Starting Async Analysis

Step 1: Classify the Input
  • http(s)://... URL → videoUrl
  • 24-char hex or asset_*assetId
  • Local file path → resolve absolute; verify exists; auto-upload via create-asset:
    Tool: mcp__twelvelabs-mcp__create-asset
    Parameters:
      file: "<absolute-path>"
    
    Surface the returned assetId to the user — they can reuse or delete it via /twelvelabs:assets. Then continue as assetId.

If a URL is given that's a YouTube/Drive/Dropbox share link, refuse — the MCP only accepts direct http(s) links to raw media.

Step 2: Build the Prompt

Use the user's question/instruction as prompt. Default: "Provide a comprehensive summary of this video including key topics, main points, and important moments."

Step 3: Start the Task

Exactly one source (videoUrl / assetId / base64Video), modelName: "pegasus1.5", plus prompt:
