Token cost

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.

Security

Grade A, and why

longform-to-shorts 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.

What it actually says

Longform To Shorts

Core Workflow

  1. Identify source asset, audience, platforms, content rights, and reuse goal.
  2. Extract moments with clear hook, standalone context, payoff, and visual or audio viability.
  3. Turn each moment into short-form script, clip note, caption, title, and CTA.
  4. Preserve accuracy and avoid removing context that changes meaning.
  5. Add editing notes: timestamps, b-roll, subtitles, on-screen text, and aspect ratio needs.
  6. Create a repurposing plan by platform and priority.

Safety Rules

  • Do not change meaning by clipping out necessary context.
  • Do not reuse third-party material without rights or attribution review.
  • Do not invent timestamps, quotes, or source claims.

Deliverable Shape

For repurposing plans, provide:

  • Source and rights notes
  • Clip candidates
  • Hook and payoff
  • Script or edit notes
  • Caption and CTA
  • Platform adaptation
  • Risk or context caveats

References

  • Read references/longform-to-shorts-checklist.md when repurposing long-form content.
Files

What ships with it

2 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.

Changes

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.
