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.

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 | $0.00048 | $0.02143 |
| Opus 5 | $0.00024 | $0.01071 |
| Sonnet 5 | $0.00010 | $0.00429 |
| Haiku 4.5 | $0.00005 | $0.00214 |
Grade A, and why
make-viral-video 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.

The opening of the file, as written. The whole thing — 170 lines — stays where its author put it; the contents beside it link to each section on GitHub.
make-viral-video
Build a short (~30-60s, 1280×720 landscape, h264+aac) news-explainer video around a single source URL or news event. Designed for shareability via the specificity-shape framing (Chi's pick 2026-05-09): one striking number, image, or quote — not a comprehensive overview.
Distinct from Lucy's recursive-meta-explorer v8-v12 lineage (which optimized for completeness). This skill optimizes for the one moment that makes someone share.
Usage
bash "$SKILL_DIR/scripts/build.sh" --topic "DoW UAP file release" --source "https://war.gov/UFO" --out results/
Produces:
results/viral-{ts}/video.mp4— the rendered videoresults/viral-{ts}/script.md— the narration scriptresults/viral-{ts}/assets/— fetched images with hash + validation logresults/viral-{ts}/build.log— full build trace (codex iterations + validation results)results/viral-{ts}/verify.sh— script to independently re-validate the build
Required tools
python3 ≥ 3.10(PIL for frame composition)ffmpeg(encode + ffprobe gate)geminiAPI key (free tier, default) ORopenaiAPI key (fallback)- Codex CLI (for script generation per pass)
Architecture
Three-phase build with self-heal
Phase 1 — Source ingestion + script generation
- Fetch the source URL (curl + Playwright fallback for JS-rendered pages)
- Codex generates a narration script + asset manifest with the specificity-shape framing:
- One striking opening fact (the hook)
- 3-5 supporting details (context)
- One closing twist or open question (the share moment)
- Asset manifest is JSON:
[{"url": "...", "alt": "...", "purpose": "hook|support|closer"}]
Phase 2 — Asset validation (the self-heal loop)
For each asset URL:
- Fetch
- Hash check: refuse duplicates (catches the v12 PR46-404-dupe pattern)
- Content-type check: must be image/* or fall back
- 404 detector: known-404-page hash list + OCR keywords ("404", "page not found", "Not Found")
- Resolution check: ≥600×400 (sub-thumb assets are not viral-grade)
- Re-fetch on failure with up to 2 retries
- If validation still fails → script regen with that asset removed, NOT a silent skip
What ships with it
8 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.

make-viral-video is a skill published in the GitHub repository sonichi/sutando (393 stars, last pushed yesterday), licensed MIT. It adds 48 tokens to every session and 2,143 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
