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: 7 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 →

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 | $0.00168 | $0.07206 |
| Opus 5 | $0.00084 | $0.03603 |
| Sonnet 5 | $0.00034 | $0.01441 |
| Haiku 4.5 | $0.00017 | $0.00721 |
Grade A, and why
video-generation-gateways 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 — 500 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Video-generation gateways
A video-generation gateway is a hosted inference aggregator that resells many third-party video models (Veo, Kling, Seedance, Hailuo/MiniMax, Luma, Wan, LTX-Video, Pika, and others) behind a single account, a single API convention, and a single bill. You send a prompt and parameters to a gateway-owned endpoint; the gateway runs the underlying model on its own infrastructure and returns a hosted result URL. This skill covers fal.ai, Replicate, and WaveSpeed as the representative gateways, and the production decisions common to the category.
This skill is about routing and operating, not about art direction. Prompt craft, shot design, and motion direction for a specific model belong to model- or craft-specific skills. Here the questions are: which gateway, going through a gateway at all, how the async job contract works, how to discover a model's schema, how to pin a version, how to cap spend, how to fail over, and whose license governs the output.
When a gateway is the right route (and when it is not)
Use a gateway when (production heuristics):
- You need several video models behind one integration — e.g. Veo for premium shots, a Kling/Seedance tier for volume, and an audio or upscale model in the same pipeline — without signing and maintaining a separate contract, key, billing relationship, and SDK per vendor.
- You want one async job contract (submit → poll/webhook → fetch) instead of learning each vendor's bespoke long-running-job protocol.
- You are model-shopping or A/B testing and want to swap model IDs without re-plumbing auth, storage, and result handling.
- You want the gateway to host input uploads and output media on a CDN so you are not building that yourself.
- Your volume does not yet justify a direct enterprise contract, or the model has no first-party public API and is only reachable through resellers.
Go direct (or reconsider) when:
- You need a first-party capability the gateway does not expose — a parameter, resolution, region, private-model hosting, or SLA the reseller has not surfaced. Gateways expose a curated subset of each model's surface.
- You need contractual data-processing terms, HIPAA/regional residency, or a signed DPA that the gateway cannot pass through from the underlying vendor.
- You are at very high, steady volume where a direct committed-use contract beats per-call reseller margin.
- You need the provider's own moderation posture rather than the gateway's added moderation layer (see Content safety below).
- Latency is dominated by gateway queueing/cold-start overhead you cannot tune, and the direct API offers provisioned throughput.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

video-generation-gateways is a skill published in the GitHub repository calesthio/generative-media-skills (170 stars, last pushed 1mo ago), licensed MIT. It adds 168 tokens to every session and 7,206 once invoked, about $0.0008 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 2026-09-03.
