A video-making workflow that turns a GitHub pull request—a proposed code change—into a video explaining its differences, commits, and affected files.

It helps create changelog videos, feature explanations, bug-fix walkthroughs, and refactor summaries from a GitHub pull request.

It makes a code change easier to understand by turning the actual pull request into a visual walkthrough instead of a product advertisement.

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.

Model	Per session	Once invoked
Fable 5	$0.00104	$0.07208
Opus 5	$0.00052	$0.03604
Sonnet 5	$0.00021	$0.01442
Haiku 4.5	$0.00010	$0.00721

Security

Grade A, and why

pr-to-video 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 yesterday.

The scan reads SKILL.md. This mod also ships 22 executable files (scripts/assemble-index.mjs, scripts/assemble-index.test.mjs, scripts/audio.mjs, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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

First, keep this skill fresh — confirm with the user before running: 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.

What ships with it

29 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.
