## Summary
Extracts all studio API routes into a shared Hono-based module at `@hyperframes/core/studio-api`.
### Architecture
- **`StudioApiAdapter` interface** — consumers inject host-specific behavior (project resolution, bundling, rendering, thumbnails)
- **Shared route modules**: projects, files, preview, lint, render, thumbnail
- **Shared helpers**: `isSafePath`, `walkDir`, `getMimeType`, `buildSubCompositionHtml`
### What this PR does
- Creates the shared module with all API routes extracted from both `vite.config.ts` and `studioServer.ts`
- Both consumers will be refactored in follow-up commits to mount this module with their own adapter
### What stays in each consumer
- **Vite**: SSR module loading, Puppeteer thumbnails, file watcher + HMR, producer HTTP proxy, multi-project scanning
- **CLI**: in-process `executeRenderJob`, local runtime serving, browser management, SPA static file serving
### Follow-up needed
- [ ] Refactor `packages/studio/vite.config.ts` to use `createStudioApi(adapter)` via `@hono/node-server`'s `getRequestListener`
- [ ] Refactor `packages/cli/src/server/studioServer.ts` to use `createStudioApi(adapter)`
- [ ] Add `./studio-api` export path to `packages/core/package.json`
- [ ] Add `hono` as peer dependency of `@hyperframes/core`
## Test plan
- [ ] Verify shared module compiles without type errors
- [ ] After consumer refactoring: all studio features work identically via both vite dev and CLI embedded servers

## Summary
- CLI render: use timestamped filenames (`project_date_time.ext`) matching the studio's naming convention, preventing overwrites of previous renders
- studioServer: read `fps`/`quality`/`format` from POST body instead of hardcoding `fps:30`/`quality:standard`/`mp4`
- studioServer: use timestamped job IDs matching the studio pattern
- studioServer: fix download endpoint to serve correct content-type for WebM
## Test plan
- [x] `hyperframes render --format webm` outputs timestamped WebM file
- [x] `hyperframes render` outputs timestamped MP4 (no overwrite)
- [x] Studio embedded server (`hyperframes dev`) renders with correct format when selected in UI
- [x] Download endpoint serves correct MIME type for WebM renders
* feat(cli): add system metrics to telemetry and expand doctor command
Enrich render telemetry with device/environment metadata (CPU, memory,
OS, Docker/CI/WSL detection) following patterns from Next.js and
Turborepo. Add speed_ratio (render time / composition duration),
per-frame capture timing, and resource usage to render events.
Expand the doctor command with CPU, memory, disk, /dev/shm, and
environment checks to help debug rendering issues on user machines.

* fix(cli): invert speed_ratio to match experiment-framework convention
composition_duration / render_time — higher is better, >1 means faster
than realtime. Matches magic_edit.render.speed_ratio in experiment-framework.

* fix(cli): wire errorMessage into render error telemetry
Address review feedback — the errorMessage field was declared in the
trackRenderError interface but never populated.

* feat(cli): add render telemetry to embedded studio server
Track render_complete and render_error from the studio's render API
endpoint (hyperframes dev). Uses dynamic imports so telemetry is
resolved at call time within the CLI package — no telemetry coupling
added to @hyperframes/studio or @hyperframes/producer.

## What
Adds 4 new composition templates and fixes structural issues across all templates.
### New templates
- **decision-tree** — animated flowchart with branching paths
- **kinetic-type** — bold kinetic typography promo
- **product-promo** — multi-scene product showcase with SVG assets (3 scenes)
- **nyt-graph** — animated data chart in NYT print editorial style
### Fixes across all templates
- GSAP updated from 3.12.2 → 3.14.2 (all templates, including warm-grain, swiss-grid, vignelli, play-mode)
- New templates restructured with proper root wrapper div, `data-duration`, sub-composition refs with `data-composition-id` / `data-width` / `data-height`
- nyt-chart: replaced `${compId}` template literal variables with hardcoded `"nyt-chart"` string — cheerio's css-what parser crashes on template literals during bundling, causing silent fallback to raw HTML without runtime injection
- nyt-chart: added DOM readiness retry for dynamically created SVG elements
- kinetic-type: removed external S3 audio URL
- All templates: GSAP script loaded in `<head>` before any scripts reference it
## Why
The new templates expand the range of content types available via `hyperframes init`. The fixes ensure all templates work correctly in the studio preview (bundler inlines sub-compositions and injects the runtime).
## Test plan
- [x] All 4 new templates render in studio preview
- [x] nyt-graph chart animates bars, line, and labels on playback
- [x] Existing templates unaffected (GSAP version bump is backwards compatible)
- [x] `hyperframes lint` passes on all templates
- [x] `generators.ts` updated with new template IDs
## Summary
- Adds `process.exit(0)` after render completes in the CLI `render` command
- Fixes the process hanging indefinitely after `npx hyperframes render --output video.mp4`
- Root cause: Node.js `fetch()` keep-alive pool (from update checks and telemetry) keeps TCP connections open, preventing the event loop from draining
- Telemetry is preserved — the `exit` handler in `cli.ts` calls `flushSync()` which spawns a detached child process
## Test plan
- [x] Run `npx hyperframes render --output test.mp4` and verify the process exits after completion
- [x] Verify telemetry events are still sent (check PostHog)
- Init "next steps" now leads with opening in an AI agent as step 1,
followed by dev preview and render as steps 2 and 3
- Interactive init shows a tip about AI agent workflow after scaffolding
- Dev command output hints that compositions can be edited with an
AI agent and changes reload automatically in the studio
The shared CLAUDE.md in scaffolded projects mentioned
hyperframes.heygen.com alongside doc topic names, causing AI agents
to guess incorrect URLs like /compositions instead of using the local
`hyperframes docs` CLI command or the correct /concepts/compositions
path. Now explicitly directs agents to use the CLI for quick reference
and llms.txt for full doc URL discovery.
- Interactive wizard is now the default when running in a TTY terminal
- Non-interactive mode (for CI/agents) uses --non-interactive flag
- Template defaults to "blank" when not specified in non-interactive mode
- --template flag skips the template picker prompt in interactive mode
- Replaces --human-friendly flag with --non-interactive (inverted logic)
npm's sigstore provenance verification requires package.json
repository.url to match the GitHub repo. Without it, publish
fails with E422 "expected to match https://github.com/heygen-com/hyperframes".
- Compute CPU_CORE_COUNT once at module level instead of calling cpus()
multiple times
- Make RenderOptions.workers required (number, not optional) — the
caller resolves the default, callees don't re-derive it
- Remove redundant existsSync guard before mkdirSync({recursive})
- Trim oversized JSDoc on defaultWorkerCount
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Replace the hardcoded default of 4 workers with a CPU-aware heuristic:
half of available CPU cores, capped at 4. Each worker spawns a separate
Chrome browser process (~256MB RAM each), so the previous default of 4
caused resource contention on smaller machines.
The new defaults:
2-core laptop → 1 worker
4-core laptop → 2 workers
8-core desktop → 4 workers
16-core server → 4 workers (capped)
Also adds --workers auto flag support, improves help text to explain
what workers do, and adds a Workers section to the rendering docs with
guidance on when to increase or decrease parallelism.

- Extract `resolveAssetDir()` helper to eliminate copy-paste across
getStaticTemplateDir, getSharedTemplateDir, getBundledSkillsDir
- Remove `counted` boolean in fallbackInstall() — collect installed
skills from first target explicitly, then copy to remaining targets
- Consolidate duplicate `installed.length > 0` check in runInstall()
into a single early return
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Replace custom git clone + copy logic with `npx skills add` from the
vercel-labs/skills ecosystem. This is the standard used by GSAP,
Remotion, and other skill providers.
- Primary path: `npx skills add heygen-com/hyperframes` and
`npx skills add greensock/gsap-skills` with `-g -y -a <agent>` flags
- Git clone + copy kept as fallback if npx is unavailable
- Added `skillsAgent` field to targets mapping CLI flags to the correct
agent names (e.g., gemini → gemini-cli)
- Removes ~80 lines of custom git/copy infrastructure
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
New HyperFrames projects created via `hyperframes init` now include:
- CLAUDE.md + AGENTS.md — teaches AI agents about skills, commands,
project structure, and framework rules (class="clip", timeline
registration, determinism). Agents know to invoke /compose-video
before writing compositions.
- .claude/skills/{compose-video,captions} — project-level skills for
immediate availability in the current agent session (global skills
require a session restart to discover).
- Updated next-steps output with `hyperframes docs <topic>` and a
link to hyperframes.heygen.com.
- Updated README with "AI Agent Skills" section documenting
`npx hyperframes skills` and `npx skills add` install paths.
- Repo-level CLAUDE.md for framework contributors.

The blank template was a bare `<div>` fragment without `<!DOCTYPE>`,
`<head>`, or `<body>`. This caused:
- Blank preview (bundler/runtime can't initialize from a fragment)
- "Failed to run lint" (parsing errors on the malformed document)
All other templates (swiss-grid, vignelli, warm-grain, play-mode) are
proper HTML documents — blank was the only outlier.
Also improves lint error reporting to show the actual error message
instead of the generic "Failed to run lint."

The SIGINT handlers that were meant to do graceful cleanup (close server,
remove symlinks) override Node's default exit behavior. If the cleanup
hangs (e.g. server.close() blocked by open connections), the process is
stuck and Ctrl+C does nothing.
Fix: don't intercept SIGINT at all. Node's default behavior exits the
process immediately on Ctrl+C. The OS reclaims the port and file handles.
Use process.on("exit") for best-effort symlink cleanup instead.
Also fixes running the CLI via `tsx` in dev mode — __CLI_VERSION__ is a
tsup build-time define that crashes at runtime without a fallback.

The embedded dev server (hyperframes dev) silently reported success even
when the requested port was already in use (e.g., by Cursor IDE on 3002).
This happened because the old isPortAvailable() probe had a TOCTOU race
and findAvailablePort() silently fell back to the original port on exhaustion.
Replace with serveWithPortFallback() that binds the real Hono server
directly via createAdaptorServer + manual listen(), retrying on EADDRINUSE.
Shows a yellow warning when auto-incrementing and a clear error when all
ports are exhausted.

- Engine: document getEncoderPreset() for MP4/WebM, VP9 alpha flags,
Opus audio in mux step
- Producer: document format field in RenderConfig, WebM usage example,
pipeline steps updated for WebM
- CLI: add render command examples in --help (including WebM overlay)
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Support rendering compositions with transparent backgrounds via
`--format webm`. VP9+alpha is the standard format for overlayable
video (captions, lower thirds, overlays).
Changes by layer:
- CLI: `--format mp4|webm` flag on render command
- Producer: threads format through RenderConfig, switches to PNG
capture and VP9 encoding when webm
- Engine: getEncoderPreset() returns VP9 config with yuva420p;
transparent page background via CDP when capturing PNG;
mux uses Opus audio for WebM; VP9 flags from production:
-row-mt 1, -auto-alt-ref 0, alpha_mode=1 metadata
- Frame capture: Emulation.setDefaultBackgroundColorOverride a=0

- Document the three dev server modes (embedded/local studio/monorepo)
- Add --port flag to dev command
- Document _meta envelope on all --json commands
- Document upgrade --check --json for agent consumption
- Document passive update notices and HYPERFRAMES_NO_UPDATE_CHECK
- Update doctor output example with Version check row
- Fix README default port from 3000 to 3002
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
- New `updateCheck.ts` utility: cached npm registry check (24h TTL),
sync `getUpdateMeta()` for _meta envelope, `printUpdateNotice()` for
passive stderr banner
- `upgrade --check --json`: machine-readable version check for AI agents
Returns { current, latest, updateAvailable }
- `_meta` envelope on all --json commands (info, lint, benchmark,
compositions): includes version, latestVersion, updateAvailable
- `doctor` shows version check as first row
- Passive update notice on stderr after command completes (skipped in
CI, non-TTY, --json, --quiet)
- Background check fires on startup (non-blocking, populates cache)

- version.ts: replace hardcoded "0.1.0" with __CLI_VERSION__ injected by
tsup at build time from package.json — fixes version mismatch where
`hyperframes --version` reported 0.1.0 while package was 0.1.4
- tsup.config.ts: add define.__CLI_VERSION__ using package.json version
- render.ts: renderDocker error handler showed "Try --docker" even when
already using --docker — changed to "Check Docker is running: docker info"
- dev.ts: add missing --port arg to embedded mode; findAvailablePort now
starts from the user-supplied port instead of hardcoded 3002

Wire up the "Export MP4" button in the studio UI. The render runs
async in the same process using @hyperframes/producer's executeRenderJob,

When installed via npx, `hyperframes dev` now starts a standalone
Hono HTTP server that serves the pre-built studio SPA and implements
the project API (file listing, read/write, preview bundling,
sub-composition rendering, runtime serving, SSE file watching).
Three modes are auto-detected:
1. Monorepo dev (running from .ts source) → spawn Vite (existing)
2. Local @hyperframes/studio installed → spawn Vite via package (new)
3. Default → embedded Hono server (new, zero extra deps needed)
Also patches the studio SPA to use EventSource SSE fallback when
Vite HMR is unavailable (production/embedded builds).

The previous approach called loadHyperframeRuntimeSource() to regenerate
the runtime IIFE, but its output lacked the trailing newline present in
the pre-built artifact, causing a SHA256 checksum mismatch with the
manifest. Copy the pre-built files from core/dist directly instead.

Empty src="" on <audio> elements causes the browser to fetch the
current page URL as the audio source, producing 404 errors in the
console during rendering. These are placeholder sound effect slots
whose src should be set dynamically when audio is configured.

The CLI's ensureBrowser() finds Chrome via env var, cached download,
or system paths (including /Applications/Google Chrome.app on macOS).
But the result was discarded — the engine's acquireBrowser() only
checked the puppeteer cache for chrome-headless-shell, passing
undefined executablePath on macOS without headless-shell installed.
Bridge the two by setting PRODUCER_HEADLESS_SHELL_PATH from the CLI's
resolved browser path before creating the render job, so the engine's
resolveConfig() picks it up.

The hyperframeRuntimeLoader uses import.meta.url to resolve
hyperframe.manifest.json as a sibling file. When bundled into the CLI
via tsup, import.meta.url points to dist/cli.js, so the sibling lookup
checks dist/hyperframe.manifest.json — which wasn't being shipped.
Copy the manifest and the canonical-named runtime IIFE into dist/ during
the build-runtime step so the loader's sibling-path resolution works in
published npm packages.

The CLI bundle uses tsup to inline @hyperframes/producer, but the
deterministicFonts module used require.resolve('@fontsource/*/package.json')
at runtime to find woff2 files on disk. When installed via npx, these
@fontsource packages don't exist, causing "Cannot find module" errors.
Replace runtime filesystem lookups with a build-time generator that reads
all @fontsource woff2 files and produces a TypeScript module with base64
data URIs. The generator runs before both producer and CLI builds, making
the bundle fully self-contained with zero @fontsource runtime dependencies.

After merging, the release tag is created automatically, which triggers npm publish.
* feat(cli): non-interactive by default, --human-friendly for UI
Following ElevenLabs CLI pattern: default mode is agent-friendly
(flag-driven, plain text output, fail fast on missing args).
Interactive clack UI is opt-in via --human-friendly.
Init command:
- --template required in default mode (errors with example if missing)
- --video / --audio flags for media input
- --skip-skills / --skip-transcribe to control optional steps
- --human-friendly enables the existing interactive prompts
- --help shows examples for every flag combination
- Transcription runs automatically in default mode (unless --skip-transcribe)
- Plain console.log output, process.exit(1) on errors
Skills command:
- Added --human-friendly flag
- Added examples to --help output
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix(cli): improve --help documentation and add --yes/--check to upgrade
- upgrade: add --yes and --check flags to skip interactive prompt
- benchmark: clarify description — preset fps/quality/worker configs
- browser: describe each subcommand (ensure/path/clear) in help
- docs: list available topics inline in --help output

* feat(cli): add whisper transcription to init flow
New modules:
- whisper/manager.ts: download/cache whisper.cpp binary + model
(~/.cache/hyperframes/whisper/)
- whisper/transcribe.ts: extract audio, run whisper, save transcript.json
Init flow changes:
- "Got a video or audio file?" now accepts audio-only files (mp3, wav, m4a)
- "Generate captions from audio?" prompt after file selection
- Transcription produces transcript.json in project root
- Graceful fallback if whisper/ffmpeg unavailable
Supports: macOS ARM64/x86, Linux x86_64. Downloads whisper.cpp v1.7.3
from GitHub releases and ggml-base.en model from Hugging Face.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix(cli): use brew/system whisper instead of downloading binaries
whisper.cpp doesn't ship pre-built macOS/Linux CLI binaries.
Use brew install whisper-cpp on macOS (auto-installs if brew available),
system PATH lookup otherwise. Model still downloaded from Hugging Face.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix(cli): simplify whisper install — detect or instruct, don't build
Remove build-from-source complexity. If whisper-cpp is found on PATH,
use it. If not, show install instructions instead of blocking:
"To generate captions, install whisper-cpp: brew install whisper-cpp"
The transcription prompt only appears when whisper is available.
When it's not, the user sees the install command and can re-run init.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat(cli): auto-install whisper via brew or build from source
ensureWhisper() now tries 4 strategies in order:
1. System PATH (whisper-cli or whisper already installed)
2. Homebrew (macOS: brew install whisper-cpp)
3. Build from source (git clone + cmake, ~30-60s)
4. Show install instructions as last resort
Init flow always asks "Generate captions?" — whisper is installed
automatically in the background if needed. No user intervention
required on macOS with Xcode CLI tools or any system with git+cmake.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix(cli): add window.__timelines guard to all templates
The studio bundler doesn't always initialize window.__timelines
before template scripts run, causing "Cannot set properties of
undefined" errors. Add defensive guard to every template.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat(cli): patch template captions with actual transcript data
After scaffolding, if transcript.json exists, replace the hardcoded
word array in the template's captions composition with the real
transcript data. The template's caption animation and styling are
preserved — only the word data changes.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix(cli): show install notice when whisper needs to be installed
When whisper-cpp isn't found, show an info message before the spinner:
"whisper-cpp not found — installing automatically..."
Then the spinner shows "Installing whisper-cpp (this may take a moment)..."
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix(cli): add muted and playsinline to all template video elements
The framework requires video elements to have muted and playsinline
attributes. All four templates were missing these, causing video
to not play in the studio preview.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix(cli): flat asset structure + separate audio tracks in templates
Assets: video, images, fonts all go at project root (not assets/ or
fonts/ subdirectories). The studio preview can't resolve relative
paths from subdirectories due to the /preview URL suffix.
Audio: added <audio> elements alongside muted <video> in all 4
templates so the video's audio plays back. The framework requires
muted video + separate audio element.
Removed assets/ and fonts/ directory creation from scaffoldProject.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix(studio): inject base tag for asset resolution in preview
The preview iframe serves bundled HTML from /api/projects/:id/preview
but relative asset paths (video.mp4, font.woff2) resolve to the wrong
URL without a <base> tag. Now injects <base href="/api/projects/:id/preview/">
so relative paths route through the static asset handler.
Also adds proper MIME types for video, audio, image, and font files
served from the preview asset route.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix(studio): serve HyperFrames runtime in dev mode
The preview runtime script had an empty src — the framework never
loaded, so video playback and clip lifecycle didn't work.
Now auto-detects packages/cli/dist/hyperframe-runtime.js and serves
it at /api/runtime.js. No env var needed in dev mode.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix(cli): filter whisper special tokens from transcript
Use --output-json instead of --output-json-full to avoid special
tokens like [_TT_485] and [BLANK_AUDIO]. Also filter remaining
bracket tokens when building the word array for captions.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix(cli): use --output-json-full for word-level timestamps
--output-json only produces segment-level timing (no tokens).
--output-json-full is required for word-level timestamps that
the captions template needs. Special tokens are filtered out
by the patchTranscript function.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat(cli): patch template durations to match uploaded video
Templates now use __VIDEO_DURATION__ placeholder that gets replaced
with the actual probed video duration. All data-duration values on
the root composition, video, audio, and caption clips are updated.
Without a video, defaults to 10 seconds.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix(cli): merge punctuation tokens with preceding word
Whisper outputs punctuation (. , ! ?) as separate tokens. These
appeared as standalone words in captions, sometimes in the wrong
group. Now merged with the preceding word during transcript
normalization.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix(cli): match both TRANSCRIPT and script variable names in templates
Three templates use `const TRANSCRIPT = [...]` while warm-grain uses
`const script = [...]`. The patchTranscript function now matches both.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix(cli): security and template fixes
- Replace shell injection risk (execSync rm) with unlinkSync in transcribe.ts
- Add GIT_TERMINAL_PROMPT=0 to whisper buildFromSource git clone
- Fix hardcoded data-duration="18" in warm-grain captions template
- Add data-start="0" to root compositions in swiss-grid, vignelli, warm-grain
- Add data-start="0" to warm-grain grain-overlay composition
- Deduplicate hasFFmpeg: remove from init.ts, import from whisper/manager.ts
- Add my-video/ and packages/studio/data/ to .gitignore
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix(cli): format warm-grain captions and fix TS nullability errors
- Format warm-grain/compositions/captions.html
- Add optional chaining on token.offsets (may be undefined)
- Use intermediate variable for lastWord to satisfy TS strict checks
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat(cli): add blank template option, smart defaults for video vs audio
- Blank template: minimal scaffolding (root composition, video, audio,
GSAP timeline) with __VIDEO_SRC__ and __VIDEO_DURATION__ placeholders
- Template defaults: video uploads default to "blank" (user brings
their own content), audio-only defaults to "warm-grain" (motion
graphics template since there's no video to show)
- Audio-only projects now tracked with isAudioOnly flag
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix(cli): address whisper review feedback
- Clean stale builds: if BUILD_DIR exists but no binary, nuke and retry
- Build failures clean up BUILD_DIR so next attempt starts fresh
- patchTranscript regex scoped within <script> blocks to prevent
matching across block boundaries
- Removed hardcoded model size hint (~148MB)
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix(cli): add missing rmSync import to whisper manager
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* chore: remove test project and lock file
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix(cli): address review items 7-12 — execFileSync, build diagnostics, WAV verification
- manager.ts: replace all execSync with execFileSync to prevent command injection
