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

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 6d 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 — 41 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Explainer

Announce at start: "I'm using the explainer skill to build the narrated walkthrough."

Inputs: <qa-dir> with qa-manifest.json, the session's plan.md (optional), the target name + optional --base-url override for the demo pass (resolved inline per orc:qa-targets; never the resolved JSON), settings explainer_style (CLAUDE_PLUGIN_OPTION_EXPLAINER_STYLE, default isometric) and explainer_voice (CLAUDE_PLUGIN_OPTION_EXPLAINER_VOICE, default af_heart).

1. Toolchain

orc-explain setup (first run: npm install kokoro-js into the user cache; model downloads on first narration). command -v ffmpeg missing ⇒ stop with one line, no explainer. animate missing ⇒ say graphic segments will be plain title cards and continue.

2. Demo footage

If <qa-dir>/demo/ lacks a .webm per @golden scenario: ( cd <repo>/<dir> && ORC_TARGET_JSON="$(orc-targets resolve <name> [--base-url <override>])" ORC_PW_OUTPUT_DIR=<qa-dir>/pw-demo npx playwright test --project=demo ) (resolve stays inline — orc:qa-targets iron rule), then orc-qa-video plan --results <qa-dir>/pw-demo/results.json and copy each video to <qa-dir>/demo/<id>.webm.

3. Script → segments.json (schema: references/segments-schema.md)

Sources, in order: the plan's slice titles + acceptance (what was built), the manifest's acceptance rows (what was proven), git log --format=%s <base>..HEAD (what changed). Never the raw diff — the script describes behaviour, not code. Shape: s01 graphic (feature title + 2–3 lines), one clip segment per golden scenario (caption = the first AC title that scenario proves; narration = one sentence of what the viewer sees), sNN graphic outcome (criteria passed/total, notable skips). Narration lines ≤ 25 words, present tense, no file names. Total target ≤ 90 seconds. style from setting, voice from setting.

4. Explainer gate (soft-inward, header Explainer; guided/full pre-approve)

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.
