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

guide 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 5d 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

showreel setup guide

The full visual guide — every step with real captured terminal output and real sample artifacts — ships with the plugin as GUIDE.html in the plugin root (<plugin>/GUIDE.html, sibling of this skills/ dir).

What to do

  1. Open it in the user's browser:
    • macOS: open <plugin>/GUIDE.html
    • Linux: xdg-open <plugin>/GUIDE.html
    • Windows: start <plugin>/GUIDE.html Resolve <plugin> from this skill's own path (two directories up from this file).
  2. Tell the user it covers, in order: install (from GitHub or a local folder), preflight, pre-warming the capture motor (one-time ~90MB Chromium download), optional ffmpeg (best gif quality) and vhs (terminal recordings), and the first self-validated annotated screenshot.

If no GUI browser is available

Don't open the HTML; run the live diagnostic instead and relay its output — it prints [ok]/[warn] per dependency plus copy-paste Setup commands:

bash <plugin>/scripts/preflight.sh
node <plugin>/scripts/ensure-deps.mjs   # pre-warm the motor now, not later
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.
