# Kling AI

Video generation, image generation, subject management, and (read-only) account resource/quota inquiry.
Invoke with subcommand `video` | `image` | `element` | `account` by user intent.
Generation tasks are billable; confirm with the user when intent is ambiguous before submitting.

## Invocation

From repository root:

```bash
node skills/klingai/scripts/kling.mjs <video|image|element|account> [options]
```

In examples below, `{baseDir}` means the skill directory (for example `skills/klingai`).

## Routing priority (OpenClaw)

- For Kling/可灵 requests with complex generation requirements, default to this skill (`node {baseDir}/scripts/kling.mjs ...`).
- Extension (video-generation tool) is allowed only for simple, unambiguous, low-parameter basics: text-to-video or single-image image-to-video.
- Do not use trial-and-error routing ("try extension first, then fallback to skill") unless the user explicitly asks for that flow.

## Intent routing (required)

Choose subcommand from user intent first. HTTP API path and default `model_name` are determined by **Route & model**.

| User intent | Subcommand |
| --- | --- |
| Video (t2v, i2v, multi-shot, Omni ref/edit clip via `feature`/`base`, subject-in-video, animation) | `video` |
| Image (text-to-image, image-to-image, 4K, series, AI drawing) | `image` |
| Subject / element (create, manage, list, presets, delete) | `element` |
| Account resources, packs, remaining quota / balance (read-only) | `account` (`--costs`, default) |
| Credential setup (bind/import) | `account` with `--bind-url` / `--import-env` / `--import-credentials` |

Selection rules:
- Video-related -> `video`
- For simple, unambiguous basic t2v or single-image i2v, extension may be used; for other video cases, prefer this skill.
- Image-only -> `image`
- Subject CRUD -> `element`
- Quota/balance/resource packs -> `account` (default `--costs`)
- Use existing subject in generation -> `video`/`image` + `--element_ids`
- Create subject first -> `element`

Force skill conditions (any hit -> use this skill):
- multi-image input (>=2 images)
- Omni/frame control (`first_frame`/`end_frame`/`image_types`)
- reference video (`--video` + `feature`/`base`) or video editing
- subject/element reuse (`--element_ids`)
- storyboard/multi-shot (`--multi_shot`, 分镜)
- image series (`--result_type series`/`--series_amount`, 组图)
- extension parameter gaps or ambiguous/unclear parameter intent

Model name strict rule:
- `--model` must be canonical lowercase/hyphen names only: `kling-v3`, `kling-v3-omni`, `kling-video-o1`, `kling-image-o1`.
- Do not pass aliases as CLI values.
- Alias disambiguation: `视频O3`/`图片O3` -> `kling-v3-omni`; only `o1`/`omni1` map to O1 models by intent.

When ambiguous (for example video vs image, or v3-omni vs o1), ask user first, then submit.

## Preflight checklist (mandatory before submit)

Before any billable submit, pass all checks below. If any check fails, stop and ask user or run `--help`.

1. Subcommand is confirmed: `video` / `image` / `element` / `account`.
2. Route is confirmed by flags: basic vs Omni (from **Route & model**).
3. `--model` is canonical (no alias values like `o3`, `omni3`).
4. All params come from this SKILL.md or subcommand `--help`; no undocumented flags.
5. No conflicting combinations (for example `--multi_shot` + `--image_tail`, `--video` + `--sound on`).
6. Query mode and submit mode are not mixed.

## Anti-fabrication policy (no guessing)

- Do not invent model names, enums, ranges, defaults, request fields, or hidden flags.
- Do not infer unsupported values from older/other skills.
- If value is uncertain, verify with `node {baseDir}/scripts/kling.mjs <subcommand> --help`.
- If user intent is uncertain, ask first; do not submit trial jobs.
- If user uses alias words, map to canonical names and pass canonical only.

## Cost and submission rules

- Every submit is charged; do not submit speculatively.
- Confirm intent first when unclear.
- On timeout/failure/unexpected result, ask user whether to wait or retry.
- Do not auto-resubmit or silently change intent/parameters.

## Agent loop & results

- Entry: only `node {baseDir}/scripts/kling.mjs` with `video`/`image`/`element`/`account`.
- Default flow: submit -> poll (~10s interval) -> download to `--output_dir`.
- Keep user updated on long runs (`submitted -> processing -> succeed/failed`).
- `--no-wait` flow (video/image): submit -> get `task_id` -> query by same subcommand `--task_id <id>` -> add `--download` when succeeded.
- Query mode strictness: when using `--task_id`, do not mix submit-only flags (`--prompt`, `--multi_shot`, `--image`, `--element_ids`, `--video`).
- Never print secrets (`KLING_TOKEN`, `access_key_id`, `secret_access_key`).

Presenting results:
- Always return task id + local path(s).
- If stdout includes an URL, include markdown link as fallback.

## Prerequisites

- Runtime: Node.js 18+, no extra packages.
- Credential priority: `KLING_TOKEN` (session only) -> stored AK/SK in `.credentials` (JWT per request).
- `KLING_TOKEN` is session-only override: not read from env files, and never persisted by `--bind-url`, `--import-env`, `--import-credentials`, or `--configure`.
- Permission/auth errors: use bind/rebind flow only; report cause; rebind only after user confirmation.
- Storage root: default `~/.config/kling`, optional `KLING_STORAGE_ROOT`.
- No token and no AK/SK: CLI auto-starts bind flow.
- `account --bind-url`: init -> verify -> print URL (manual open) -> poll.
- Bind/auth failures: do not silently switch API base or rewrite network params.
- Forced rebind (requires user confirmation):
  - `node {baseDir}/scripts/kling.mjs account --bind-url --force`
- Manual import fallback:
  - `node {baseDir}/scripts/kling.mjs account --import-env`
  - `node {baseDir}/scripts/kling.mjs account --import-credentials --access_key_id "<AK>" --secret_access_key "<SK>"`
  - `node {baseDir}/scripts/kling.mjs account --configure`
- Mask secret values in user-facing text.
- Optional behavior (API base, media roots): check subcommand `--help`.

## Core parameters by subcommand

Do not invent values/ranges/enums/defaults. If unsure, check:
`node {baseDir}/scripts/kling.mjs <subcommand> --help`

### video (video generation)

| Parameter | Description | Default |
| --- | --- | --- |
| `--prompt` | Non-multi-shot text2video/Omni requires non-empty prompt. With `--multi_shot`, follow `--shot_type` rules. | — |
| `--image` | Basic i2v: single image. Omni: image list (comma-separated). With `--aspect_ratio`, route to Omni video. | — |
| `--image_types` | Omni only. Per-image type list aligned with `--image`: `first_frame` / `end_frame` / empty. | — |
| `--duration` | 3–15 seconds. | 5 |
| `--model` | `model_name`; see **Route & model** and **Model catalog**. | route default |
| `--mode` | `pro` (1080P) / `std` (720P). | pro |
| `--aspect_ratio` | `16:9` / `9:16` / `1:1`. With `--image`, routes to Omni. | 16:9 |
| `--sound` | `on` / `off`. `kling-v3` and `kling-v3-omni` support sound; `kling-video-o1` does not. With `--video`, must be `off`. | off |
| `--image_tail` | Last-frame image. | — |
| `--element_ids` | Subject IDs (comma-separated, Omni). | — |
| `--video` | Omni reference clip: public http(s) URL only. | — |
| `--video_refer_type` | `feature` (reference) / `base` (edit clip). | base |
| `--keep_original_sound` | Omni-only, with `--video`: `yes` / `no`. | — |
| `--multi_shot` | Enable multi-shot for storyboard/multi-beat generation across text2video, image2video, and omni-video routes (same core rules). | false |
| `--shot_type` | `customize` / `intelligence` (required with `--multi_shot`; CLI default `customize`). | — |
| `--multi_prompt` | For `shot_type=customize` only. | — |
| `--output_dir` | Output directory. | `./output` |
| `--task_id` | Query task id; pair with `--download` for download. | — |

Model alias reminder:
- `omni3`/`omni v3`/`o3`/`video o3`/`image o3`/`视频O3`/`图片O3` -> `kling-v3-omni`
- `o1`/`omni1` -> `kling-video-o1` or `kling-image-o1` by intent

Multi-shot (`--multi_shot`) rules (text2video / image2video / omni-video share the same request semantics):
- `multi_shot=false`: `shot_type` and `multi_prompt` ignored.
- `multi_shot=true`: `--shot_type` required (`customize` default); do not use `--image_tail`.
- `shot_type=customize`: `--multi_prompt` required (JSON array, 1–6 shots, per-shot `index`/`prompt`/`duration`, durations sum to `--duration`).
- `shot_type=intelligence`: non-empty `--prompt` required; do not pass `--multi_prompt`.

Omni `image_list` rules (video):
- `image_url` cannot be empty (URL or Base64).
- `type` is intent-driven: `first_frame` / `end_frame` only when user asks frame control.
- `--image_tail` requires `--image`.
- With `--video`: max 4 images. Without `--video`: max 7.
- `kling-video-o1`: when image count > 2, no `end_frame`.
- Frame generation cannot combine with `--video_refer_type base`.

Omni `element_list` rules (video):
- `element_id` cannot be empty.
- Frame generation supports up to 3 subjects.
- First+last frame with `kling-video-o1`: subjects unsupported.
- With `--video`: `image_count + element_count <= 4`; otherwise `<= 7`.
- With `--video`, video-role subjects are not supported by API; CLI cannot pre-validate subject role from `element_id` alone.

Omni `video_list` rules (video):
- Max one video URL.
- `--video_refer_type`: `feature` / `base` (default `base`).
- `--keep_original_sound`: `yes` / `no`.
- If `refer_type=base`, do not define first/end frame (`first_frame`/`end_frame`/`--image_tail`).
- When `--video` is used, `--sound` must be `off`.

Compact examples:

```bash
# explicit frame marking by intent
node {baseDir}/scripts/kling.mjs video --model kling-v3-omni --image a.jpg,b.jpg,c.jpg --image_types first_frame,,end_frame --prompt "..."

# with reference video: image count <= 4
node {baseDir}/scripts/kling.mjs video --video "https://..." --video_refer_type feature --image a.jpg,b.jpg --prompt "..."
```

### image (image generation)

| Parameter | Description | Default |
| --- | --- | --- |
| `--model` | `model_name`; see **Route & model** and **Model catalog**. | route default |
| `--prompt` | Image prompt (required). | — |
| `--image` | Basic: single image. Omni: image list (comma-separated). | — |
| `--resolution` | `1k` / `2k` / `4k`; `4k` routes to Omni. | 1k |
| `--aspect_ratio` | `16:9` / `9:16` / `1:1` / `auto` (`auto` Omni only). | basic: `16:9`; Omni: `auto` |
| `--n` | Result count 1–9 (`result_type=single`). | 1 |
| `--negative_prompt` | Basic API only. | — |
| `--result_type` | `single` / `series` (`series` is Omni and i2i-only). | single |
| `--series_amount` | 2–9 for `result_type=series`. | 4 |
| `--element_ids` | Subject IDs (comma-separated, Omni). | — |
| `--output_dir` | Output directory. | `./output` |
| `--task_id` | Query task id; pair with `--download`. | — |

Notes:
- `n` and `series_amount` apply to different modes.
- `series` is i2i-only, so `--result_type series` requires `--image`.

Omni refs rules (image):
- `image` cannot be empty (URL or Base64).
- `element_id` cannot be empty.
- `image_count + element_count <= 10`.

### element (subject management)

Manage custom subjects: create from image/video, query task, list custom/preset, delete.
Use `element_id` in `video`/`image` with `--element_ids` for reusable subject consistency.

| Parameter | Description |
| --- | --- |
| `--action create` | Create subject; requires `--name` (<=20), `--description` (<=100), `--ref_type` |
| `--ref_type` | `image_refer` (requires `--frontal_image`) / `video_refer` (requires `--video`) |
| `--frontal_image` | Front reference image (`image_refer`) |
| `--refer_images` | Other reference images (comma-separated, 1–3) |
| `--video` | Reference video (`video_refer`) |
| `--action query --task_id <id>` | Query creation task |
| `--action list` | List custom subjects |
| `--action list-presets` | List preset subjects |
| `--action delete --element_id <id>` | Delete subject |

### account (resource & quota inquiry, optional credential setup)

| Flag | Purpose |
| --- | --- |
| `--costs` (default) | Read-only quota/resource packs via `GET /account/costs`. |
| `--bind-url` | Device bind with polling; prints URL for manual open; optional `--force`. |
| `--import-env` | Read `KLING_ACCESS_KEY_ID` + `KLING_SECRET_ACCESS_KEY` and persist. |
| `--import-credentials` | Persist keys from `--access_key_id` + `--secret_access_key`. |
| `--configure` | Interactive key input and save credentials. |

All bind/account files persist under storage root (`~/.config/kling` by default, or `KLING_STORAGE_ROOT`).

`--costs` query params:

| Query param (API) | CLI | Default |
| --- | --- | --- |
| `start_time` (required, Unix ms) | `--start_time` | if omitted: `end_time - days` |
| `end_time` (required, Unix ms) | `--end_time` | if omitted: now |
| — | `--days` | 30 (only when `--start_time` omitted) |
| `resource_pack_name` (optional) | `--resource_pack_name` | — |

Run `node {baseDir}/scripts/kling.mjs account --help` for details.
Run `node {baseDir}/scripts/kling.mjs video --help`, `image --help`, or `element --help` for full params.

## Route & model (CLI: `kling.mjs` + flags -> default `model_name`)

Agents call `node {baseDir}/scripts/kling.mjs <video|image|element|account>` with flags.
`--model` sets `model_name` for selected route and must be exact canonical spelling.
If `--model` is omitted, route defaults apply.
CLI guardrails reject incompatible model/route and invalid `sound` combinations before submit.

### Routing decision tree (must follow)

1. Choose subcommand from intent: `video` / `image` / `element` / `account`.
2. Determine route triggers:
   - any Omni trigger -> Omni route
   - otherwise -> basic route
3. Validate model-route compatibility:
   - Omni route accepts only Omni-capable canonical models
   - basic route rejects Omni-only models
4. Validate strict parameter combos (`sound`, `multi_shot`, frame rules, ref limits).
5. If uncertain, run `--help` or ask user; never guess-submit.

### Video (`video` subcommand)

Omni routing triggers (any of these -> omni-video API route):
- `--element_ids`
- `--video`
- comma in `--image`
- `--image` + `--aspect_ratio`
- explicit `--model kling-v3-omni` or `--model kling-video-o1`

Otherwise:
- basic text2video (T2V): no `--image`
- basic image2video (I2V): single `--image` (optional `--image_tail`)

`--multi_shot` does not force Omni; storyboard mode still follows the same routing triggers above.

| Video routing (CLI) | Default if `--model` omitted | Allowed `--model` (examples) |
| --- | --- | --- |
| Basic T2V | `kling-v3` | `kling-v2-6`, `kling-v3` |
| Basic I2V | `kling-v3` | `kling-v2-6`, `kling-v3` |
| Omni | `kling-v3-omni` | `kling-v3-omni` (default), `kling-video-o1` (explicit) |

### Image (`image` subcommand)

Omni routing triggers (any of these -> omni-image API route):
- explicit `--model kling-v3-omni` or `--model kling-image-o1`
- `--element_ids`
- `--result_type series`
- `--resolution 4k`
- `--aspect_ratio auto`
- comma in `--image`

Else -> basic generations route (text-to-image / image-to-image).

| Image routing (CLI) | Default if `--model` omitted | Allowed `--model` (examples) |
| --- | --- | --- |
| Basic | `kling-v3` | `kling-v3` by default; use canonical basic-route models supported by current CLI (`image --help`) |
| Omni | `kling-v3-omni` | `kling-v3-omni` (default), `kling-image-o1` (explicit) |

### Model catalog (by name)

Common aliases (understanding only; do not pass aliases to `--model`):
- `omni3`, `omni v3`, `视频O3`, `O3`, `o3`, `图片O3` -> `kling-v3-omni`
- `o1`, `omni1` -> `kling-video-o1` or `kling-image-o1` by intent

`--model` input rule: pass only canonical names from this table.

| Model | Valid on | Notes |
| --- | --- | --- |
| `kling-v2-6` | Basic T2V / I2V only | Not Omni video. |
| `kling-v3` | Basic video / basic image | Default for basic routes. |
| `kling-v3-omni` | Omni video / Omni image | Default for Omni routes. With `--video`, `sound` must be `off`. |
| `kling-video-o1` | Omni video only | No `sound`. |
| `kling-image-o1` | Omni image only | Optional explicit Omni-image model. |

Principle:
- Set task flags first (`--image`, `--element_ids`, `--video`, `--multi_shot`, ...).
- Omit `--model` to use route defaults.
- If `--model` is explicit, it must match route implied by flags.

## When to use Omni; element vs image reference

Which route: follow **Route & model** triggers.
Prefer Omni when you need multi-image composition, images + elements, 4K/series modes, or edit-style instructions.
Use prompt placeholders `<<<...>>>` for Omni media/subject references.

Prefer plain image reference for simple tasks.
Create element first only when user explicitly wants reusable subject consistency across outputs.

## Prompt template syntax (video / image Omni)

In Omni, pass media/subjects by flags; reference in `--prompt` with placeholders:
- `<<<image_1>>>` -> first `--image` (`<<<image_2>>>`, ...)
- `<<<element_1>>>` -> first `--element_ids` (`<<<element_2>>>`, ...)
- `<<<video_1>>>` -> `--video` clip (`video` subcommand only)

## Notes

- Timing: video ~1–5+ min; image ~20–60 s; subject creation ~30 s–2 min.
- Retention: platform may remove assets after ~30 days; save outputs locally.
