Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 | $0.00074 | $0.00764 |
| Opus 5 | $0.00037 | $0.00382 |
| Sonnet 5 | $0.00015 | $0.00153 |
| Haiku 4.5 | $0.00007 | $0.00076 |
Grade A, and why
video-explainer 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 — 69 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Video Explainer
Version note: v0.3.0-rc.1 / 2026-07-22 / Add the first guarded brief-to-video workflow with script-bound review receipts, a no-key demo path, and local verification. Keep upload, account access, credentials, private voice assets, and hosted rendering out of scope. Rollback: remove this skill and continue using the legacy scripts directly.
Produce a local video and evidence packet. Never upload or publish from this skill.
Install
This Skill orchestrates a local clone of claude-video-kit; it does not bundle the renderer. From the repository root, install the runtime and register the Skill with:
npm ci --prefix remotion
npx skills add runesleo/claude-video-kit --skill video-explainer
For repository development, run commands from the repository root.
Workflow
-
Run the read-only doctor before changing a project:
node scripts/video-explainer.mjs doctor --output <output-directory>Read setup-and-doctor.md when doctor blocks or the environment is new.
-
Convert the brief into
script.json. Keep claims traceable, use supported slide types, and target 9:16. Read brief-to-script.md for the input/output contract. -
Require an independent review. Write
review-input.json, then run:node scripts/video-explainer.mjs review <project> --input <project>/review-input.jsonRead review-gate.md for the six required checks. If any check is
fixorblock, revise and review again. Never render from that receipt. -
Render only after a current pass receipt:
node scripts/video-explainer.mjs render <project>On macOS, use
--demo-qualityonly for a credential-free first success. It forces the built-insayvoice and script-timed captions; label the result as demo-quality. Read render-and-verify.md before running a custom project.
What ships with it
6 files 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.
