name: hyperframes-cli description: > Use the HyperFrames CLI development loop: init, add, catalog, capture, lint, check, snapshot, compare, grade-compare, preview, play, present, beats, keyframes, single or batch render, publish, cloud, cloudrun, feedback, lambda, doctor, browser, info, upgrade, skills, compositions, docs, benchmark, telemetry, transcribe, auth, tts, and remove-background. Also use when diagnosing build or render failures. validate, inspect, and layout are deprecated aliases; use check. Covers local, HeyGen-hosted cloud, AWS Lambda, and Google Cloud Run rendering.

HyperFrames CLI

Run commands as npx hyperframes ... unless project instructions provide a wrapper. Obey the wrapper when present. The CLI requires Node.js 22 or newer and FFmpeg.

Development loop

1. Scaffold: npx hyperframes init <project> or capture a site. In non-TTY mode, pass --non-interactive --example=<name>.
2. Author: write the composition using /hyperframes-core.
3. Get fast feedback while editing: run npx hyperframes lint after the first HTML pass and after structural changes.
4. Run the final gate: run npx hyperframes check; it reruns lint before opening the browser. Do not prepend a redundant standalone lint invocation. Add --snapshots for annotated overview frames and finding crops.
5. Inspect sub-compositions: when index.html mounts data-composition-src, capture midpoint snapshots and inspect each mounted scene.
6. Open the final Studio preview: run npx hyperframes preview, hand the timeline project URL to the user, and ask whether to revise or render.
7. Render only after approval: use draft quality for iteration and high quality for delivery.
8. Verify the output: confirm the file exists, is non-empty, and has a plausible duration.

# Fast iteration check; repeat while authoring as needed.
npx hyperframes lint

# Required final gate; includes lint.
npx hyperframes check
npx hyperframes preview
npx hyperframes render --quality high --output out.mp4
test -s out.mp4
ffprobe -v error -show_format out.mp4

check runs lint first, then uses one browser session and one seek pass to audit runtime errors, failed requests, layout, *.motion.json assertions, and WCAG contrast. Persistent findings gate the exit code; transient entrance or exit findings are informational. Use --strict to gate warnings. validate, inspect, and layout remain aliases for compatibility but must not appear in new instructions or scripts.

Two different preview surfaces

Do not confuse these states:

Surface	When it may open	Purpose
Storyboard board	Before composition checks, only when storyboard: yes	Review plan cards and wireframe sketches. Open ?view=storyboard#project/<name>.
Final composition preview	After check passes	Review the assembled timeline before render. Open #project/<name>.

The early board is not approval of the final video. Rendering always requires the final approval defined by hyperframes-core/references/review-loop.md.

Sub-composition smoke test

Static audits cannot catch every mount failure. When the project uses sub-compositions, capture at least one visible midpoint for each host slot:

npx hyperframes snapshot --at <t1>,<t2>,<t3>

Treat tiny unstyled content, canvas-sized icons, missing hero elements, or timeline-registration timeouts as render-blocking mount defects. See hyperframes-core/references/sub-compositions.md for the corresponding fixes.

Agent conventions

• Prefer --json for agent and CI calls. Server-mode render, preview, and play do not provide ordinary JSON output; preview --selection --json and preview --context --json are query-mode exceptions.

• doctor --json always exits zero. Gate on its payload:

  npx hyperframes doctor --json | jq -e '.ok' >/dev/null
  

• Non-TTY mode is automatic. init requires --example there; use --non-interactive to force deterministic behavior on a TTY.

• Use one HYPERFRAMES_RUN_ID for all commands in the same verification loop.

• Use --strict, --strict-all, and --strict-variables when the corresponding warnings, variables, or CI conditions must gate the render.

• JSON paths redact the home directory as $HOME; do not try to reverse the redaction.

• When a hosted cloud project approaches or exceeds the 200 MB upload limit, use cloud render --dry-run --json and follow the .hyperframesignore investigation in references/cloud.md. Never ignore an asset merely because it is large.

• Never render merely because checks pass. Pause at the final preview and wait for approval.

Studio-directed edits

When the user refers to “this element” or the current selection, query Studio instead of guessing:

npx hyperframes preview --context --json --context-fields selection

Use selection.target.hfId when available, otherwise its selector and source file. If the result reports no-selection, ask the user to click the element and rerun. Request only the context slices you need; use --context-detail full only for computed styles or editable text metadata. Full behavior and failure codes live in references/preview-render.md.

Render choices

Need	Command
Fast local iteration	npx hyperframes render --quality draft
Final local delivery	npx hyperframes render --quality high --output out.mp4
Reproducible container render	npx hyperframes render --docker --strict --output out.mp4
Local variable-driven batch render	npx hyperframes render --batch rows.json --output "renders/{name}.mp4"
HeyGen-hosted zero-infrastructure render	npx hyperframes cloud render
Self-managed distributed AWS render	npx hyperframes lambda render <project> --width 1920 --height 1080 --wait
Self-managed distributed GCP render	npx hyperframes cloudrun render <project> --width 1920 --height 1080 --wait

Use cloud rendering when the user wants hosted rendering without local Chrome, FFmpeg, or AWS. Use Lambda only when AWS ownership is a requirement. Use Cloud Run only when GCP ownership is a requirement. Read the matching reference before running any cloud path.

After verifying a successful render, send one feedback report unless telemetry is disabled or the user opted out:

npx hyperframes feedback --rating <0-10> --comment "<specific result or friction>"

Keep clean-run feedback concise. For any bug or friction, capture a reproduction packet before submitting; do not send only a symptom summary. Include the rerunnable command (relative to the project directory — feedback is submitted to a public channel, so do not paste absolute paths, home-directory prefixes, or user/machine identifiers), expected versus actual behavior, exact error (also strip absolute paths from stack traces — keep basename + line, drop the leading directory), whether output completed/fell back/failed, workaround, and repro-project status. For a rating ≤ 7 that describes a visual defect (black frame, flicker, corrupt output, wrong frame, blank output, other visual anomaly), also include a COMPOSITION_STRUCTURE: block — a privacy-preserving structural anatomy (element census + attribute presence + timeline shape) so maintainers can pattern-match against known bug families without the composition ZIP. Agents auto-fill this via the composition-census helper; the human user does not fill it by hand. If the issue did not reproduce again, say so and still include the last failing command and logs. Use --file-issue only with consent: it publishes a minimal reproduction to a public URL. The required packet format and privacy warning live in references/preview-render.md.

Read the matching reference before running a command

The following references and owning skills are mandatory command contracts, not optional background reading. Before running a command in the table, read its matching row.

Need	Reference
init, capture, skills	references/init-and-scaffold.md
lint, check, motion sidecars, snapshot	references/lint-validate-inspect.md
compare, grade-compare, variable-driven render --batch	references/compare-and-batch.md
beats for an existing project's Studio beat grid	references/beats.md
preview, play, render, publish, Studio context, feedback	references/preview-render.md
doctor, browser management	references/doctor-browser.md
auth, HeyGen-hosted cloud rendering, and template variables	references/cloud.md
AWS Lambda deployment and rendering	references/lambda.md
Google Cloud Run deployment and rendering	references/cloudrun.md
info, upgrade, compositions, docs, benchmark, telemetry, media preprocessing	references/upgrade-info-misc.md

For composition variables, also read /hyperframes-core → references/variables-and-media.md. For hyperframes add and hyperframes catalog, use /hyperframes-registry. Before hyperframes present, read /slideshow; before hyperframes keyframes, read /hyperframes-keyframes. For TTS, transcription, captions, or background removal choices, use /media-use.

The specialized commands are deliberately documented by their owning workflows:

npx hyperframes present <project-dir> --port 3004 --no-open
npx hyperframes beats <project-dir> --json
npx hyperframes keyframes <project-dir> --json

present serves a navigable deck with presenter and audience synchronization. beats is the standalone Studio beat-grid utility defined in references/beats.md. keyframes surfaces seek-safe animation and motion-path diagnostics.
