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 high
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 →
- high Tool Misuse · line 229 Tool parameters are crafted to achieve unintended or unsafe behavior. Parameter abuse can bypass intended safety checks (e.g. shell=True, --force, dangerous glob patterns).Fix: Validate all tool parameters against an allowlist. Reject dangerous parameter values (shell=True, --force, -rf /) and use safe defaults.
- medium Excessive Agency · line 214 Skill allows unbounded resource consumption (API calls, storage, compute). Without rate limits or quotas, a compromised or misbehaving agent can cause denial-of-service or cost overruns.Fix: Set explicit rate limits, timeouts, and resource quotas for API calls, file operations, and compute. Implement circuit breakers for runaway loops.
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 | $0.00050 | $0.18365 |
| Opus 5 | $0.00025 | $0.09182 |
| Sonnet 5 | $0.00010 | $0.03673 |
| Haiku 4.5 | $0.00005 | $0.01836 |
Grade A, and why
runway-video scanned grade A with 2 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 9d 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.

Runway Video
Use this skill for server-side integrations with the documented Runway Developer API at https://api.dev.runwayml.com. It covers Runway-native video models and makes partner models, still-image generation, the consumer web app, Recipes, Workflows, Characters, and third-party gateways explicit out-of-scope branches.
Research cutoff: 2026-07-10.
Evidence language
Interpret statements in this skill as follows:
- Fact — stated in a first-party Runway source or visible in the official OpenAPI-generated SDK.
- Claim — Runway marketing or policy language that may depend on plan or contract.
- Heuristic — an operational recommendation derived from the facts; validate it for the deployment.
- Unknown — not established by the reviewed first-party public material. Do not silently fill it in.
When a volatile fact affects money, safety, payload validity, or data governance, re-open the cited first-party page before production use.
Start with scope, consent, and an execution mode
Before designing a request, obtain all of the following:
- The desired mode: text-to-video, image-to-video, video edit, or performance transfer.
- Whether Runway-native models are required or a partner model is acceptable.
- Output duration, dimensions, delivery format, audio expectation, and iteration budget.
- Rights to every prompt, image, video, face, voice, performance, mark, and music input.
- Explicit permission from each depicted or heard person. Runway's Usage Policy prohibits using another person's image, video, or audio without permission.
- A disclosure/provenance plan when realistic synthetic media could mislead viewers.
- Data classification, approved regions/subprocessors, retention requirement, and whether the organization's contract actually provides no-training or zero-data-retention terms.
- One of these execution modes:
- Plan/dry-run — default. Validate, price, and print an approval digest. Perform no paid API creation.
- Approved create — only after an exact request digest, bounded maximum cost, and explicit environment gates match.
- Resume — poll an already recorded task ID; never create a replacement.
- Cancel/delete — a separate destructive operation with a separate approval. Never infer it from a timeout.
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.

runway-video is a skill published in the GitHub repository calesthio/generative-media-skills (170 stars, last pushed 2mo ago), licensed MIT. It adds 50 tokens to every session and 18,365 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 2 findings (makes network calls, runs shell commands). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
