Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00073 | $0.01385 |
| Opus 5 | $0.00036 | $0.00692 |
| Sonnet 5 | $0.00015 | $0.00277 |
| Haiku 4.5 | $0.00007 | $0.00138 |
Grade A, and why
sync-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 8d 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.
How it starts
The opening of the file, as written. The whole thing — 115 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Synchronous Video Analysis
Analyse a video using TwelveLabs AI and return the result inline. Works on:
- A previously-indexed
videoId(legacy, Pegasus 1.2 only). - A direct http(s) URL (Pegasus 1.5).
- A previously-uploaded
assetId(Pegasus 1.5). - A local file path — this skill uploads it as an asset internally first, then analyses it (Pegasus 1.5).
For videos longer than 1 hour, or for time-based metadata extraction, use the async-analyze skill instead.
When to Use This Skill
The user wants a quick text/JSON answer about a single video and:
- Provides a video reference (URL, file path, asset ID, or indexed videoId) AND a question / instruction; or
- Asks a general question and references "this video" / "that video" / "the video I just indexed".
For multi-segment structured extraction (e.g. "find every product mention with timestamps"), use the async-analyze skill — that supports analysisMode: "time_based_metadata".
Model Default
| Input type | modelName |
|---|---|
videoId |
pegasus1.2 (forced — the MCP rejects 1.5 + videoId) |
| Anything else | pegasus1.5 |
Only override to pegasus1.2 when the user explicitly says so ("use 1.2", "legacy model").
Instructions
Step 1: Classify the Input
Look at what the user gave you:
- 24-char hex string referred to as a "video" →
videoId. ForcemodelName: "pegasus1.2". http(s)://...URL →videoUrl. UsemodelName: "pegasus1.5".- 24-char hex or
asset_*referred to as an "asset" or "uploaded thing" →assetId.modelName: "pegasus1.5". - Anything that looks like a file path → resolve to absolute; verify the file exists; upload it first:
Capture the returnedTool: mcp__twelvelabs-mcp__create-asset Parameters: file: "<absolute-path>"assetId. Tell the user the asset was created and that they can reuse or delete it via/twelvelabs:assets. Then continue as if they had given you anassetId.
Step 2: Build the Prompt
If the user gave a question, use it as prompt. Otherwise default to:
"Provide a comprehensive summary of this video including key moments, topics covered, and important details."
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

sync-analyze is a skill published in the GitHub repository twelvelabs-io/twelve-labs-claude-code-plugin (23 stars, last pushed 3mo ago), licensed MIT. It adds 73 tokens to every session and 1,385 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
