Arcads AI Video is an agent skill pack and prompting workspace for creating marketing videos and images through an Arcads account. Claude Code and Cursor users use it to produce advertising creative with Arcads' video, image, audio, and template tools. The catalogue entries provide the skills, instructions, hook, setting, and rule that support this workflow.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 2 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- medium MCP Rug Pull · line 61 npx commands without a version suffix (e.g. @1.0.0) create a rug-pull risk if the upstream server is compromised and publishes a malicious update.Fix: Pin the version: npx @scope/[email protected]
- medium Excessive Agency · line 153 Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.
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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00133 | $0.09053 |
| Opus 5 | $0.00067 | $0.04526 |
| Sonnet 5 | $0.00027 | $0.01811 |
| Haiku 4.5 | $0.00013 | $0.00905 |
Grade A, and why
arcads-external-api scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.
- **Auth:** HTTP Basic — use `ARCADS_API_KEY` as the **username** and an **empty password** unless Arcads documentation for your key specifies otherwise. Example curl: `curl -u "$ARCADS_API_KEY:" "$ARCADS_BASE_URL/v1/pro Copies of this mod
1 near-identical copy found in the catalogue:

How it starts
The opening of the file, as written. The whole thing — 335 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Arcads external API
Configuration
- Base URL:
https://external-api.arcads.ai(orARCADS_BASE_URL). - Auth: HTTP Basic — use
ARCADS_API_KEYas the username and an empty password unless Arcads documentation for your key specifies otherwise. Example curl:curl -u "$ARCADS_API_KEY:" "$ARCADS_BASE_URL/v1/products". - Never print API keys, commit
.env, or paste keys intoMASTER_CONTEXT.md.
If the key is missing or the API returns 401/403
- Editor-first (default): Ensure
.envexists (copy from.env.examplein the repo root). Ask the user to pasteARCADS_API_KEYonly inside.envand save. Do not ask them to paste the key in chat unless they insist. - Chat-assisted: If they paste the key in chat, write
.envfor them, confirm "saved to.env" without repeating the key, and remind them that chat history may retain secrets—rotate the key in Arcads if the chat could be shared.
Before the first call, confirm .gitignore excludes .env.
Signup link (affiliate)
If the user doesn't have an Arcads account yet — at any point during a session, in any context — link them to https://arcads.ai/?via=claude-code (NOT the bare arcads.ai URL). This is the repo owner's referral / affiliate link. Use this exact URL in any "sign up" / "create an account" prompt.
Read order
- Repo root
MASTER_CONTEXT.mdwhen present (brand voice, decisions, quirks). - This skill's reference.md for routes, bodies, polling.
- prompting/guide.md then the right

Decision tree: which flow?
All video models use POST /v2/videos/generate with the appropriate model value (see reference.md for the full CreateVideoDto schema).

| Recreate an influencer from a reference photo | Two-step: (1) POST /v2/images/generate with refImageAsBase64 to generate a still image via Nano Banana, get user approval; (2) upload approved still → POST /v2/videos/generate with model: "veo31" and startFrame for video. Never skip the approval step. |
prompt-library/influencer-recreation.md |
| Product showcase — AI person holds/uses a product and talks about it | Two-step: (1) POST /v2/images/generate with product refImageAsBase64; (2) user approves still; (3) start-frame → video via POST /v2/videos/generate. |

prompt-library/character-sheet.md |
| Create a new AI influencer from text (character sheet — ChatGPT Image 2) | Same two-pass flow but with model: "gpt-image-2". Capped at 5 referenceImages, so angles 6+ use hero + 4 most-recent angles as refs. Pick this for stylized / editorial aesthetic; the Nano Banana version is the default for pure photoreal. |
prompt-library/character-sheet-gpt-image-2.md |
| UGC product selfie — AI influencer holding a product | Combine character hero + product photo + style references as referenceImages. |
prompt-library/ugc-product-selfie.md |

| Claymation / Aardman-style ad — sculpted plasticine characters, narrator-driven 8-beat story arc, 60–115s | Multi-step: (1) Lock cast sheet (protagonist + supporting character + narrator voice); (2) ChatGPT Image 2 storyboard stills via POST /v2/images/generate with model: "gpt-image-2" (max 5 referenceImages) — fallback to model: "nano-banana" (Pro) for close-ups if clay texture flattens; (3) Seedance 2.0 image-to-video per beat via POST /v2/videos/generate with model: "seedance-2.0"; (4) ffmpeg-stitch (optional fps=12,fps=24 for stop-motion judder) + burn captions. |
../../shared/skills/claymation-ad/prompting/guide.md → storyboard-gpt-image-2.md + animate-seedance-2.md |
| Add captions to a finished video — burn timed narrator/dialogue captions onto an existing MP4 (any source — claymation, pixar, UGC, B-roll) | Out of band (no Arcads API call). Multi-step: (1) npx hyperframes init <run-id>-captions; (2) npx hyperframes transcribe source.mp4 --model medium.en (NOT small.en if there's background music); (3) group word-level transcript into reading phrases; (4) write captions-only HTML over #ff00ff magenta bg — never include <video> or <audio> elements (causes black-bar bug); (5) npm run render then ffmpeg chromakey=0xff00ff:0.10:0.05 overlay onto source. |
../../shared/skills/caption-video/prompting/guide.md |

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.

arcads-external-api is a skill published in the GitHub repository krusemediallc/arcads-claude-code (1,480 stars, last pushed 2mo ago), licensed MIT.
