description: "Turn a GitHub pull request (a PR URL, owner/repo#N, or 'this PR' in a checked-out repo) into a code-change explainer video — changelog, feature reveal, fix, or refactor walkthrough built from the diff, commits, and files: the input is a code change, not a website. Not a product promo (/product-launch-video) or a no-PR topic explainer (/faceless-explainer). Unclear → /hyperframes."

> **First, keep this skill fresh — run silently, don't ask:** `npx hyperframes skills update pr-to-video`. A fast no-op when everything is current; otherwise it refreshes this skill plus the core domain skills it depends on before you rely on them.

> **media-use**: Before sourcing audio/images/logos, call `/media-use` to resolve BGM/SFX/images from the HeyGen catalog and brand logos from their official sources. Run `--adopt` first to register existing assets. See `/media-use` skill.

PR to HyperFrames

Use this skill to ingest a GitHub pull request, understand the change, plan a code-change explainer, and build it frame by frame in HyperFrames. The input is a **code change** (read via `gh`), not a website — there is **no capture step and no real assets** beyond the contributors' avatars.

> **The front door is `/hyperframes`.** You are the orchestrator. Run each step, verify its gate, and only then continue. This skill is for a **GitHub pull request** (a code change). Any other intent, a bare "make a video", or any uncertainty → read `/hyperframes` first — the intent layer owns every route decision, and a fresh creation arriving here without `BRIEF.md` goes through it anyway (Setup's opening rule).

You are the orchestrator. Work in the resolved external `PROJECT_DIR`, never in the caller repository by default. Run steps in order and pass each gate before continuing. User-gated steps are Step 0, Step 3, and Step 6. Read `../hyperframes-core/references/brief-contract.md` before Step 0 — it defines the gate types and how `BRIEF.md`'s `flow`/`storyboard` derive the mode that governs the Step 3/4/6 gates. Do every step yourself except Step 5, where you dispatch a bounded pool of frame workers. Do not put design or motion rules here; those live in the frame-worker sub-agent, this skill's local `../hyperframes-animation/rules/` + `../hyperframes-animation/blueprints/`, and `hyperframes-creative`.

Workflow: Step 0 setup → `hyperframes.json`; Step 1 ingest → `capture/extracted/` + `assets/<login>.png`; Step 2 design system → `frame.md`; Step 3 storyboard/script → `STORYBOARD.md` and `SCRIPT.md`; Step 3.1 audio → `audio_meta.json`; Step 4 visual design → enriched `STORYBOARD.md`; Step 5 frames → `compositions/frames/NN-*.html` and `index.html`; Step 6 final render → `renders/video.mp4`.

Step 0: Setup

Goal: Enter with a confirmed brief — including the **PR reference** (a full URL, an `<owner>/<repo>#<N>` ref, or "this PR" in a checked-out repo) — create the HyperFrames project, and make the brief durable. The style is always **code-editorial** (fixed at Step 2, never asked).

**The brief is confirmed by the intent layer, not by questions asked here.** Opening rule, in order: **(1)** `BRIEF.md` exists → read it and ask nothing — the brief is settled, and its `flow`/`storyboard` derive the mode (brief contract § 1). **(2)** No `BRIEF.md` but the project exists (`hyperframes.json` / `STORYBOARD.md` on disk) → resume from the storyboard's frontmatter and the recorded preferences; never re-interrogate a half-built project. **(3)** Neither — a fresh creation request that arrived here directly → read `/hyperframes` and run its intent layer (`references/intent-interview.md`): it checks recipes and remembered defaults, and conducts this route's questions — including the PR-size → length doctrine, which lives whole in `../hyperframes/references/routes/pr-to-video.md` — then hands back the locked brief. Edit requests skip all of this — go do the edit.

Resolve the project directory before doing any other work. Preserve a user-supplied project directory; otherwise use the durable external cache location printed by the resolver. Never create `videos/` in the caller repository:

PR="<url | owner/repo#N>"
if [ -n "${EXPLICIT_PROJECT_DIR:-}" ]; then
  PROJECT_DIR="$(node <SKILL_DIR>/scripts/project-dir.mjs --pr "$PR" --project-dir "$EXPLICIT_PROJECT_DIR")"
else
  PROJECT_DIR="$(node <SKILL_DIR>/scripts/project-dir.mjs --pr "$PR")"
fi
echo "PR-to-video project: $PROJECT_DIR"
node <SKILL_DIR>/scripts/preflight.mjs

The capability preflight runs before fetch, story work, audio, or frame dispatch. If the installed CLI cannot run the validation command required by this skill, stop with its upgrade instruction rather than spending the run's context first.

Initialize only if `$PROJECT_DIR/hyperframes.json` is missing. Its basename comes from the PR, such as `acme-sdk-pr-1842`; never use the workspace name or a timestamp.

`npx hyperframes init "$PROJECT_DIR" --non-interactive --example=blank --skill=pr-to-video` — `init` checks the installed skills against the latest on GitHub and updates the global set if any are out of date.

Every relative-path command below runs with `$PROJECT_DIR` as its working directory. Examples without an explicit subshell mean `(cd "$PROJECT_DIR" && …)`; never change the caller repository's working tree.

**Write `BRIEF.md` immediately after init** (never before — `init` refuses a non-empty directory): the intent layer's locked brief, shape per `../hyperframes-core/references/brief-format.md`. Resolve `<MEDIA_DIR>` as the installed `/media-use` skill directory. Then record each preference-backed answer with `node <MEDIA_DIR>/scripts/prefs.mjs record --hyperframes .` (`brief-format.md` names the subset). If the intent layer adopted a recipe, run `node <MEDIA_DIR>/scripts/recipe.mjs use --hyperframes . --name <name>`; it copies its `frame.md` into the project (Step 2 is then skipped) and returns the skeletons Step 3 drafts from. A recipe fills answers,
