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

demo-slideshow-edit 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 1mo 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

Demo Slideshow Edit

Overview

Use this skill when the best output is a curated still-frame or segment-based reel rather than a full narrated playback. The slideshow must remain source-backed and evidence-linked.

Inputs

  • storyboard frames or screenshots
  • selected spans from video.shots.json, segment.evidence.json, or events.json
  • source .demo.yaml or QA flow/report
  • target duration, aspect ratio, and audience

Workflow

  1. Select frames or spans that show state changes clearly.
  2. Reject frames that expose secrets, private data, or unreadable UI.
  3. Define the sequence with durations, crop/zoom notes, and transition notes.
  4. Prefer simple transitions and stable framing over decorative effects.
  5. Record the source path, evidence links, and output path in the artifact manifest when available.
  6. Produce a render plan or command. Do not claim the MP4 is approved until evidence and safety checks pass.

Output

Return:

  • source run directory
  • ordered frame/span list
  • duration and aspect ratio
  • output media path
  • review surface path, if generated
  • checks needed before handoff

Guardrails

  • Do not fabricate app states that were not captured.
  • Do not crop away failures, warnings, or key context.
  • Do not use external stock or music unless the user explicitly asks and licensing is recorded.
  • Keep generated slideshow media out of git unless explicitly promoted.
Files

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.

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.
