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 | $0.00027 | $0.03186 |
| Opus 5 | $0.00014 | $0.01593 |
| Sonnet 5 | $0.00005 | $0.00637 |
| Haiku 4.5 | $0.00003 | $0.00319 |
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 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.

/twelvelabs:async-analyze - Async Video Analysis
Asynchronously analyse a video using Pegasus 1.5 (default). Accepts a direct 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 status to retrieve the result.
Use this when:
- You have a video URL, local file, or asset but no indexed
videoId - The video is over 1 hour long (sync analyze is capped at 1 hour)
- You want structured time-based metadata segmentation
- You want multimodal prompting with reference images
For already-indexed videos under 1 hour, /twelvelabs:sync-analyze is faster.
Usage
/twelvelabs:async-analyze <url-or-path-or-asset-id>
/twelvelabs:async-analyze <url-or-path-or-asset-id> "<prompt>"
/twelvelabs:async-analyze status [task-id]
/twelvelabs:async-analyze list
/twelvelabs:async-analyze delete <task-id>
User provided: $ARGUMENTS
Arguments
- First positional — one of:
- Direct http(s) URL to a raw media file (YouTube/Drive/Dropbox share links not accepted)
- Absolute or relative local path to a video file (this command will upload it as an asset for you)
- A previously uploaded asset ID (24-char hex string starting with a digit)
prompt- Optional: natural-language question or instruction (max 2000 tokens). Drives general analysis. Cannot be combined withanalysisMode: "time_based_metadata".status- Check task status. Optionally provide a task ID.list- List recent async analyse tasks (supports filters — see List Flow).delete- Delete a task by ID.
Optional advanced parameters (when the user asks for them)
| Param | Purpose |
|---|---|
modelName |
"pegasus1.5" (default) or "pegasus1.2" (legacy, deprecated). Set 1.2 only if the user explicitly requests it. |
promptV2 |
Structured prompt with <@name> references to attached images (Pegasus 1.5 only). Mutually exclusive with prompt. Shape: { inputText, mediaSources: [{ name, mediaType: "image", url|assetId|base64String }] }. Up to 4 mediaSources. |
temperature |
0-1, default 0.2 |
maxTokens |
Pegasus 1.2: 1-4096. Pegasus 1.5: 2048-32768 (default 32768). |
jsonSchema |
JSON Schema (Draft 2020-12) — constrain general-mode output to structured JSON. Cannot combine with segmentDefinitions. |
startTime / endTime |
Clip the analysis window (Pegasus 1.5 only). end - start ≥ 4. Mutually exclusive with segmentDefinition.timeRanges. |
analysisMode |
"time_based_metadata" — switches output to per-segment structured extraction. Requires segmentDefinitions. Pegasus 1.5 only. |
segmentDefinitions |
1-10 segment definitions; each has id, description, optional fields (typed schema), optional mediaSources (up to 4 reference images), optional timeRanges. |
minSegmentDuration / maxSegmentDuration |
Constraints on auto-extracted segment lengths. time_based_metadata only. Mutually exclusive with per-definition timeRanges. |
customId |
Caller-supplied tracking ID (1-64 chars, alphanumeric + -_). Round-trips through get-analyse-task and list-analyse-tasks. |
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.

async-analyze is a command published in the GitHub repository twelvelabs-io/twelve-labs-claude-code-plugin (23 stars, last pushed 3mo ago), licensed MIT. It adds 27 tokens to every session and 3,186 once invoked, about $0.0001 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.
