* docs(media): document automatic proxying for hostile codecs
Describes the shipped behavior: which input codecs render, that live preview
auto-proxies what the browser cannot decode, where the cache lives, and how to
turn it off. Carries the skills notes and the hardening design documents.
* docs(media): align proxy guidance with runtime
## What
Part 2 of the GSAP seek-safety rules (stacks on #2611): the two rules that touch existing catalog content and required reconciliation with an existing rule.
- `gsap_relative_value_second_writer` (error) — a relative var value (`y: "-=15"`) on a property whose target has another writer **active at the relative tween's start**. The relative base is captured at tween init, which reads a different partial state per seek path: sequential seek inits it mid-entrance, a cold render worker inits it at the entrance's end state, and the element teleports at chunk boundaries (production case: all scene nodes jumping ~20px mid-scene). Writers that complete strictly before the start are safe (children render in start-time order within a seek pass — verified against gsap 3.15.0) and are not flagged; neither are single-writer relatives, `from()`/`fromTo()`, build-time `gsap.set`, or relative position parameters (`"+=0.5"`). Selector resolution bails on combinators and cross-composition scoping rather than guessing. Findings aggregate per tween pair and report the overlap window.
- `gsap_timeline_set_initial_hide` (warning) — initial-state hiding via `tl.set(target, vars, 0)` on a paused timeline is not rendered while the playhead sits at exactly 0, so frame 0 shows the unhidden state (verified against gsap 3.15.0: opacity stays 1 after `tl.time(0)`, applies only past 0). Exempt when the target is already hidden by authored CSS/inline styles or a standalone `gsap.set()`, and only sets preceding every tween in source order qualify (mutated position variables resolve to their initial binding in the parser — outro hard-kills don't masquerade as position-0 sets).
- Reconciliation: `gsap_fullscreen_overlay_starts_visible`'s fixHint previously recommended exactly the flagged `tl.set(sel, {opacity:0}, 0)` pattern; it now recommends authored CSS hiding or immediate `gsap.set()`.
- Docs for the full rule family in `docs/packages/lint.mdx`.
## Corpus impact (the reason this is its own PR)
These two rules are the ones that fire on repo-shipped content:
- `gsap_relative_value_second_writer`: 4 errors in `gooey-metaball`, all genuine overlaps. Measured with gsap 3.15.0: ballD diverges **3.31 xPercent / 1.99 yPercent (~8px/5px at 240px ball size)** between sequential and cold seek — a permanent base offset that appears as a teleport at a chunk boundary. Real but modest; happy to fix the block in a follow-up (start the drift at the entrance's end, or use absolute `fromTo`).
- `gsap_timeline_set_initial_hide`: 10 warnings across the catalog after the CSS-hidden exemption (down from 54 pre-narrowing); spot-checked as genuine frame-0 pops with no authored hide (e.g. `vfx-text-cursor` `#phrase-b`).
Adversarially reviewed the same way as #2611 (393-composition corpus + gsap semantics experiments); FP classes fixed and locked as negative tests: precede-only second writers, descendant/cross-composition selector mis-joins, CSS-hidden re-assertions, mutated position variables.
## Tests
Full `packages/lint` suite green at 440 tests including multi-composition roots; `tsc`, oxlint, fallow audit clean.
* feat(studio-server): serve H.264 proxies from the preview route
Wires the codec manifest and the transcoder into the preview surface: the route
negotiates a proxy via a query param and serves it through the existing range
and ETag machinery, composition HTML carries a codec map for the runtime, and
hostile assets pre-warm so a first play does not wait on a cold transcode.
Exposes the three subpath exports the CLI surfaces consume upstack.
Drops the TEMP fallow entry added with the transcoder: it has real importers now.
* fix(studio-server): publish media proxy exports
* fix(parsers): scan HTML comments linearly
* feat(cli): let projects opt out of automatic proxying
Adds media.autoProxy to hyperframes.json plus --proxy/--no-proxy flags, and
forwards the resolved value into the studio and preview servers and the vite
adapter. Lands before the runtime slice that turns auto-proxying on, so the
switch exists before there is any behavior to switch off.
* fix(cli): align media config schema

Windows users with the OS temp dir on a small system drive have hit
C: exhaustion mid-render (Slack ts=1784219488 · CLI v0.7.58 · win32
15 GB / 8-core, ~5500 frames). The engine already honors
HYPERFRAMES_EXTRACT_CACHE_DIR for relocation, but the knob was
undocumented and invisible in diagnostics — the reporter had to piece
together a 4-flag compound workaround including EXTRACT_CACHE_DIR=off.
Changes:
- Extract the env-var resolver into a public engine API
(resolveExtractCacheDir, defaultExtractCacheDir,
EXTRACT_CACHE_DIR_DISABLED_ALIASES) with a typed resolution shape
distinguishing "disabled by user" vs "default" vs "env override".
- Add a Frames-cache check to `hyperframes doctor` that reports the
effective directory, its free space, source (env or default), and
fails with a relocation hint when <2 GB free at that mount.
- Add `hyperframes render --frames-cache-dir <path>` as discoverable
CLI sugar for the env var, including the opt-out aliases
(off/none/false/0) and CWD-safe absolute-path resolution.
- Document the flag in docs/packages/cli.mdx with the field-signal
citation, and add a render example row for the Windows workflow.
- Cover both surfaces with unit tests (6 doctor cases + 4 engine
cases including all disabled-alias variants).

* docs(skills): make the core set the default install on every surface
A field test showed an agent with a real 'make videos' intent installing
all 19 skills: at install time, every surface it could read pointed at the
full set, while the core-eager / workflow-on-demand design only exists
inside hyperframes/SKILL.md - unreadable until after the install decision.
Two traps made full-install the documented default:
- The README Quick Start used 'skills add --yes': skills.sh force-detects
agent environments into non-interactive mode, and a non-interactive run
without --skill installs all 19. Dropping --yes fixes the human path
(the picker opens with nothing pre-selected), but not the agent path.
- marketplace.json listed the full 'hyperframes' bundle first, under the
name an agent installing 'hyperframes' matches; core-skills sat second.
Changes, each behavior verified by an isolated run:
- README Quick Start drops --yes (humans get the picker; verified via a
pty capture that nothing is pre-selected) and points agents and
non-interactive runs at 'npx hyperframes skills update', which from a
clean HOME installs exactly the 8 core skills, refreshes stale ones and
prunes unpublished ones on an existing machine, and is idempotent.
- CLAUDE.md and the docs install guide lead with the same one-liner;
--all is reworded to explicit-request-only at every surface.
- marketplace.json puts core-skills first and both descriptions steer the
default choice; the full entry keeps auto-discovery (no allowlist),
per the skillsManifest core-pin test (56/56 pass).
* docs(skills): close the same install trap in AGENTS.md
Review follow-up on the core-default change: AGENTS.md still carried a
bare 'npx skills add heygen-com/hyperframes' - no --full-depth, and the
same non-interactive-installs-everything trap the README fix closed.
AGENTS.md is the first file Codex/Cursor-family agents read for repo
intent, so it leaked the full-set default to exactly the readers the
core-default policy targets. It now leads with the same core-set
one-liner and policy line as CLAUDE.md.
* docs(guides): add Claude Design → Send to HyperFrames single-file import guide
Self-contained authoring guide for the 'Send to HyperFrames' MCP import path
(distinct from the download-ZIP flow): single self-contained HTML wire format,
the composition contract the importer validates, inline-brand-assets fidelity
rules (base64 data: URIs), no bundled/splash artifacts, keep-the-original-as-
reference, a complete worked skeleton, the animation-pattern catalog, and
determinism rules. Reviewed for technical accuracy against a known-good
imported+rendered composition.

* docs(send-to guide): assets must be resolvable (inline OR fetchable URL), not inline-only
Large media can exceed the import size cap, so "inline everything" is wrong for it,
and the import tool description now states "resolvable refs." Align the guide: inline
data: URIs preferred (fonts/images/logos — the only fully self-contained form), a
publicly-fetchable absolute URL allowed for large media, and explicitly forbid relative
paths / local-file variables / expiring-or-private hosts (the media-expiry trap).

Adds a `--timeout <ms>` CLI flag (and `HYPERFRAMES_TRANSCRIBE_TIMEOUT_MS`
env var) plus a model-slowdown factor in the auto-scaled default so
`hyperframes transcribe` doesn't hard-fail with `spawnSync ETIMEDOUT`
on slow CPUs running heavier whisper models.
Field-signal ts=1784165471 (win32/arm64 emulating x64 on Snapdragon,
CLI 0.7.59) reported the failure on a 63s wav with `-m medium` at ~13x
realtime — the historical 10x-realtime scale (PR #2463) gave 10.5 min
while the machine needed ~13.7 min. Splitting audio and merging offsets
was the manual workaround.
- Add `--timeout <ms>` and `HYPERFRAMES_TRANSCRIBE_TIMEOUT_MS` (min 5000).
Explicit override bypasses auto-scaling; still capped at 12h.
- Add per-model slowdown factor (tiny 0.5, base 0.7, small 1, medium 2,
large 4, large-v3-turbo 2). Multiplied into the 10s/audio-second
baseline so medium/large get proportional headroom while `small.en`
(the default) preserves the historical safety window.
- Wrap whisper's spawn error with a discoverability hint naming
`--timeout`, the env var, and the effective timeout when the child
was killed by SIGTERM/ETIMEDOUT (mirrors PR #2504 protocol-timeout).
- Docs: new `--timeout` row in `docs/packages/cli.mdx` Flags table.
Regression coverage in `packages/cli/src/whisper/transcribe.test.ts`
(56 tests) and `packages/cli/src/commands/transcribe.test.ts` (5 tests):
- Model factor per known name + case-insensitive + safe unknown fallback.
- 63s field-signal case on medium.en → 1_260_000ms (was 630_000ms).
- Explicit override honored below the auto floor + capped at 12h.
- Model factor ignored when overrideMs is set.
- SIGTERM/ETIMEDOUT detection + augmented message contract.
- CLI rejects below-minimum `--timeout` with error naming both the flag
and the 5000ms floor.

* docs(registry,skills): surface code-highlight 0-based indexing and opacity-reveal sweep guidance
From the 2026-07-14 CLI feedback digest (skills-owner action): a user
building code teaching videos hit two authoring gaps.
1. code-highlight's `line` is intentionally zero-based (`line: 1` =
second displayed line) but the warning lived only in pr-to-video's
code-vocabulary reference — nowhere an author actually touches the
value. Call it out at the block-use sites: the `__BLOCK` declaration
itself, the registry-item description, and the motion-graphics
catalog map.
2. Opacity-only code-typing tripped `sweep_static` for that user, who
worked around it with a slow host y-drift. The sweep fingerprint
does include per-element opacity, so document the actual trap (a
reveal that settles before the sampled window, then holds a static
frame) and the idiomatic fixes (spread the reveal / keep a blinking
caret alive) in the check reference — and pin the fingerprint's
opacity sensitivity with a regression test covering both the
visibility-floor crossing and a mid-fade value change.
* docs(catalog): regenerate code-highlight page from updated registry-item description
Only the code-highlight page is committed: a full generate-catalog-pages
run also surfaces ~34 blocks missing from the git-tracked catalog index
(pre-existing drift on main), which belongs in its own chore PR.
* feat(studio,cli): per-frame board comments, self-refreshing storyboard, status-aware preview landing
Per-frame comment boxes on the storyboard board batch into
.hyperframes/frame-comments.json (a resubmit wins per frame; unconsumed
comments on other frames are kept). Submitted-but-unconsumed comments
stay visible — a toolbar banner plus a per-tile echo — until the agent
consumes the file; the banner also says what to do next (reply anything
in the agent chat).
The board keeps itself current: GET /projects/:id/signature exposes the
watcher-cached project signature, the storyboard payload carries the
signature it was derived from, and the view polls at 2s (hidden tabs
skipped, re-checked on visibility), refetching in place with no loading
flash. Posters bake the signature into their URL so tiles fill in as
sketches land and a poster that failed mid-write retries on the next
version; the empty state upgrades itself when STORYBOARD.md appears,
and its handoff prompt now points the agent at the review loop and uses
the parser's real status vocabulary (outline, not planned).
preview lands the browser on the storyboard view while the board is the
review surface — any frame built, or pure planning (srcs declared, none
on disk yet) — and on the timeline once the video is assembled.
* feat(skills): the review loop — plan, sketch, build as one shared process
hyperframes-core/references/review-loop.md is the single source for the
three-pass collaborative review: the plan proposed on a live board
(§ 1), wireframe sketches marked built with one layout question (§ 2 —
real words on plain blocks, run no CLI; a confirmed board is itself a
valid deliverable when the user asked for a storyboard, not a video),
the build dressing confirmed layouts (§ 3, worker or inline), and the
final look (§ 4). Autonomous runs skip every gate and keep one question
before render.
The three narrative workflows' Steps 3/4/6 collapse to references plus
their sketch stand-ins (captured-asset blocks for product-launch-video,
plain code panels for pr-to-video); the confirmed-sketch handoff stays
in each frame-worker prompt. general-video plans on a board for
multi-scene narrative pieces in collaborative mode — its sketch pass is
layout-before-animation with the user watching. The router treats
"I want a storyboard" as a process request rather than a route, and
closes exploratory intake by recommending a route plus how the run will
review.
The supporting contracts land next door: the comments channel (silent
submit, one reply picks it up, check the file before the words) in
brief-contract § 1; the sidecar schema and the built status rung in
storyboard-format; the mode question asked first and alone in the three
workflows' Step 0.
* feat(media-use): user memory — remembered preferences and frozen recipes
Two tiers of memory on media-use's existing two-tier storage split.
Preferences (lightweight): confirmed brief answers — destination, aspect,
language, mode, voice, style preset — recorded to the project's
.media/preferences.json (committed, the team inherits it) and promoted
to the personal ~/.media/preferences.json once the same value is
confirmed in two different projects (a sightings ledger accumulates the
cross-project evidence user-side, since project files can't see each
other). prefs.mjs get/record; merge reads project-over-user; a changed
value restarts its provenance.
Recipes (heavyweight): one approved run frozen as a named, versioned
bundle — frame.md, the storyboard skeleton (structure kept: durations,
transitions, srcs, Video direction; statuses reset to outline; content
blanked to per-frame fill-ins naming the beat's role), and the confirmed
brief values. Named folders, not content hashes: re-freezing bumps
version and archives <name>@v<N>; a freeze is already confirmed, so it
promotes to the user tier immediately. recipe.mjs freeze/list/use, plus
resolve --type recipe --entity <name> delegating like grade/lut.
16 new node --test cases; the media-use lib suite is 168/168.
* feat(skills): wire user memory into the brief and the review loop
brief-contract § 2 gains Remembered defaults: read the merged
preferences before Round 2 and let a remembered value become the
recommended option with a receipt naming its source project. Memory
changes the default, never the question — every ask-marked field still
gets asked, and what the request says this time beats what was picked
last time. Record only what the user actually confirmed (a defaulted
voice nobody chose is not an answer; a "go" that accepts the
recommended defaults is). The first record announces itself once;
after that the receipts carry the reminder. In autonomous mode a
remembered value becomes the decided value, receipt included.
The three narrative workflows read the remembered defaults before
Round 2, record the confirmed answers at the Step 0 gate, record the
chosen preset at the Step 2 gate (pr-to-video excepted — its preset is
fixed), and fall back to the remembered voice when the request names
none. general-video's discovery reads the same defaults.
Recipes wire in at both ends: Step 0 checks for a matching recipe
before the mode question — one question, plural-aware, and adopting
one fills the brief, skips the design step, and drafts the storyboard
from the frozen skeleton while every review gate still runs. The
review loop's final look (§ 4) offers the freeze once after approval,
and the confirmation teaches the recall phrase — the name is something
the system reminds the user of, never something they must remember.
The router recognizes a named recipe or "like last time" as a route.
* docs(skills): the sketch pass names check, not the deprecated validate
* feat(skills): intent-layer references — process, route briefs, capability menu, BRIEF.md format

* fix(scripts): sandbox npx-leak guard - private npm global prefix keeps npx on the branch CLI
* chore(skills): resync manifest hash after formatter pass reflowed general-video tables
* fix(skills): recipe freeze reads workflow from BRIEF.md; style_preset records require workflow scope
Two holes found by a live companion-run freeze: the agent-supplied --workflow
contradicted the run's actual workflow (recipe.json said faceless-explainer,
brief-skeleton said general-video), and the style_preset lookup missed because
the preference had been recorded under the bare key.
- freezeRecipe resolves the workflow from BRIEF.md frontmatter; the flag is a
fallback for briefless projects and a contradicting flag is ignored (noted).
- recordPreference refuses a bare style_preset — the scoped key is the only
writable shape; freeze tolerates legacy bare records via read fallback.
- review-loop § 4 / media-use SKILL / brief-format wording follow the machinery.
Add a `core-skills` entry to .claude-plugin/marketplace.json declaring
the core skill set (the /hyperframes router, the hyperframes-* domain
skills, and media-use). The upstream vercel-labs/skills CLI reads that
entry's `skills` array for its interactive picker: the core set renders
under a "Core Skills" group and everything else falls into "Other", so
a human running `npx skills add heygen-com/hyperframes --full-depth`
can tell the always-needed core set apart from the on-demand creation
workflows — mirroring the core/on-demand tiers `hyperframes skills
update` already enforces (isCoreSkill in skillsManifest.ts).
The array deliberately lives on a separate marketplace entry, NOT on
plugin.json or the `hyperframes` entry: Claude Code treats a manifest
`skills` array as that plugin's skill allowlist (verified against
claude CLI), so attaching it to the full plugin would narrow it from
all skills to the core 8. As a side effect the new entry is itself a
coherent Claude Code plugin — `core-skills@hyperframes` installs just
the core set — while `hyperframes@hyperframes` keeps auto-discovering
everything.
A new pin test keeps the marketplace list in lockstep with isCoreSkill
and the skills/ tree (alongside the existing FALLBACK_CORE_SKILLS pin),
and asserts the full plugin carries no allowlist. Agent installs are
unaffected — the upstream CLI detects agent environments and installs
non-interactively, and the hyperframes CLI always passes explicit
--skill flags.

* docs(skills): add cloud render + variables to CLI skill, media-use generative use cases
The hyperframes-cli skill only documented self-managed AWS Lambda rendering; the
zero-infra HeyGen-hosted `cloud render` path (a real, shipped command with its
own docs page) was absent from every skill, so agents never surfaced it.
- hyperframes-cli: add `cloud` to the frontmatter verb list + entry point; new
Cloud and Variables sections; new references/cloud.md distilled from
docs/deploy/cloud.mdx; routing + workflow rows.
- media-use: add image-to-video recipe (heygen video create type:image) plus a
table of other HeyGen generative use cases (photo avatar, digital twin, video
translation, lipsync, voice design) in references/operations.md; surface them
in the SKILL coverage/provider rows.
- Sync README + docs/guides/skills.mdx catalog entries to mention cloud render.
* docs(media-use): point HeyGen generative use cases at --request-schema
Verified against the installed heygen CLI (v0.3.0): no capability gap that would
need the raw API. Replace hardcoded body-field lists with a pointer to
`heygen video create --request-schema` (self-documenting, can't rot), correct
the image-to-video motion_prompt/expressiveness support, and add the
cinematic_avatar, ai-clipping, and photo-avatar creation paths.
* fix(skills): correct media-use manifest hash (clean-tree regen)
The prior regen was polluted by the gitignored skills/media-use/eval-report.html
(a suppressed mv error left it present), so the committed media-use hash didn't
match a clean checkout. Regenerate with no untracked artifacts present.
Two real conflicts:
- docs/guides/prompting.mdx: modify/delete. This branch already deleted
it (383dd3568, replaced by the docs/prompting/* multi-page structure);
main separately fixed one line in the old file (cf7c1d760: lint+validate
-> the new consolidated `check` command). Kept the deletion — a
redirect to /prompting/overview already exists in docs.json — and
ported the same check-command fix forward into the two new-structure
pages that still had the stale lint+validate phrasing
(examples.mdx, rules-and-anti-patterns.mdx), so main's fix isn't lost.
- skills-manifest.json: auto-generated, regenerated fresh via
packages/cli/scripts/gen-skills-manifest.ts rather than hand-resolving
the JSON conflict markers.
Everything else auto-merged cleanly (no conflicts) — this pulls in
main's independent work since the branch diverged (media-use v2, the
check command consolidation, studio timeline updates, etc).

Learned from a strong example prompt (not reused verbatim — different
subject, same technique): a stop-motion/hand-animated look wants
irregular timing, but true unseeded randomness breaks HyperFrames'
determinism guarantee (same seek must always render the same frame).
The correct pattern is a PRNG seeded once at composition start, stepping
elements between held positions rather than tweening continuously —
distinct from rule 1's continuous ambient idle, which is a different
tool for a different texture.
Kept separate from "The grammar, measured" (rules 1-6, empirically
videoed) since there's no rendered proof for rule 7 yet — the new
section and example are illustrative, not claimed as verified.

* feat(cli): coordinate-frame layout findings in check
Four production compositions shipped with 100-600px layout drift, each a
different coordinate-frame confusion the check graded info or missed
entirely: viewport pixels written as container left/top, gsap x/y
treated as absolute position, a -350px margin fighting flex centering,
and stage-relative path coords drawn into a nested SVG.
Three new layout findings close the class:
- positioned_out_of_parent: an absolute/fixed element rendering mostly
outside its positioning ancestor (warning) — the parent needs no
overflow clipping, which is what let container_overflow miss it.
- box_out_of_canvas: a painted panel breaching the canvas (warning) —
text is canvas_overflow's, media is frame_out_of_frame's, painted
boxes were nobody's.
- connector_detached: a connector path whose endpoints land far from
every anchorable element (warning) — measured coordinates drawn into
an SVG with a different origin.
canvas_overflow additionally promotes from info to warning when held
across samples AND the breach exceeds 5% of the canvas.
All three are persistence-tiered and respect data-layout-allow-overflow.
Verified against the four incident compositions: every one now surfaces
its drift as held warnings (previously: info or silence).
* fix(cli): harden coordinate-frame findings against review false positives
Reworks all three findings after two-lens review (adversarial FP hunt in
real Chrome + maintainer pass):
- escaped_container (was positioned_out_of_parent): uses offsetParent
(transform-aware, skips fixed-as-canvas), exempts fully-detached
callouts within an attachment allowance while still flagging
touching-but-mostly-outside drift.
- panel_out_of_canvas (was box_out_of_canvas): paint alone qualifies
(flat solid panels were a false negative), fully off-canvas rects are
parked entrances and stay silent, pointer-events:none marks decorative
layers, hero-sized breaches warn while small bleeds stay info.
- connector_detached: endpoints via getPointAtLength + getScreenCTM
(viewBox, preserveAspectRatio, group transforms, every command type),
defs/marker/clipPath subtrees skipped, word-boundary connector naming,
containment tier limited to opaque non-ancestor targets (a text-bearing
wrapper contains its own diagram's endpoints).
- canvas_overflow promotion requires partial visibility — a fully
off-canvas rect is a parked entrance, not drift.
Verified: the four incident compositions still surface their drift as
held warnings; the review's false-positive repros (fixed HUD, callout,
parked entrance, corner bleed, marker arrowheads, g-transform and
viewBox-scaled connectors) are clean at warning level. Docs and the CLI
skill reference now describe the coordinate-frame findings.
* fix(cli): panel ownership is geometric — direct-text panels were a silent false negative
A painted panel whose direct text stays in-bounds while its box breaches
the canvas produced neither finding: canvas_overflow measures the text
range and panel_out_of_canvas skipped every own-text element. Skip the
panel finding only when the element's own text ALSO breaches (that
geometry belongs to canvas_overflow); pin the message/fixHint wording of
all three findings with positive assertions; document the SVG-internal
anchor blind spot.
* fix(cli): classify panel decoration by paint kind, not pointer-events
pointer-events:none exempted the framed-painting incident's gold frame
layers — hero content that happens to disable hit-testing. Decoration is
now gradient-only paint (spotlights, textures, vignettes); url() images,
solid fills and borders are content regardless of pointer-events.
* fix(cli): add fixHint to the test-local AuditIssue shape
* fix(cli): gradient stops decide content vs decoration; ownership matches canvas_overflow's tolerance
A gradient with any solid stop (alpha >= 0.6) is content — heroes and
cards painted with linear-gradient were invisible under the blanket
gradient exemption; all-translucent stops (spotlights, vignettes) stay
decoration. The text-ownership check now uses the audit tolerance that
canvas_overflow itself fires at, making the contract strict-mutex: any
text breach past that tolerance cedes the element, so a shallow 20px
text breach no longer double-reports.
Every other creation workflow gets either a dedicated page or an
explicit routing/contrast section inside a related one (website-to-
video inside product-launch.mdx, slideshow inside music-and-
slideshows.mdx). /remotion-to-hyperframes had neither — its only
mention anywhere in the 29-page guide was one line in overview.mdx's
install table.
Covers what to hand the agent (the exact source file, since a Remotion
project can register several Compositions), the one-way/no-reverse-
export scope, the lint-blocker categories that make the skill refuse
rather than approximate (useState/useEffect state machines, third-
party UI kits), and why SSIM validation against the Remotion original
is part of the deliverable, not optional. Added to the "By video type"
nav group in docs.json.

Scaffolded projects' npm run check now invokes the single check command
instead of chaining lint, validate, and inspect (three Chrome boots
become one). The CLI skill, its correctness reference, the entry skill's
capability map, README/docs catalog rows, the Mintlify CLI page (new
check section, deprecation banner on inspect), template CLAUDE/AGENTS
(byte-identical), root CLAUDE/AGENTS, and every creation-workflow skill
that taught the old sequence all point at check. snapshot keeps its
standalone sections; validate/inspect stay documented as deprecated
aliases with their check equivalents.
Validates 16 more published prompts end-to-end (variants across every
video type, caption styles, overlays with proven alpha, code diff and
highlight, edit verbs against the real attribute map, a generated-avatar
talking-head through embedded-captions, a presented slideshow deck) and
fixes every prompt flaw the builds surfaced. Adds keyword-to-render
grids for the easing, camera, and marker vocabulary; two more worked
visual specs with renders; a measured before/after pair proving the
motion grammar (frozen frames vs all-alive, 211KB vs 2.5MB); before/
after render pairs on editing and generated-artwork pages; and proof
renders on the overview.

Five-way review of the section against docs.json, catalog pages, and
skills. Fixes: stale /hyperframes-media skill row (real name /media-use)
plus missing music-to-video and slideshow workflow rows; caption
identity misattributions (keynote/documentary are scene-embedded, stomp
carries no rail); prompts violating the guide's own ambient-idle rule;
grounded keying rationale (u2net_human_seg); broken forward references;
nested-backtick code spans; brand casing and frontmatter dash
consistency throughout.

Moves all 28 example/validation renders to the docs' canonical media
host (s3://heygen-public via scripts/upload-docs-images.sh) and points
every embed at static.heygen.ai instead of HeyGenVerse asset URLs.

Runs validation builds for the primary prompt on every new feature page
(all pass lint/validate/render) and applies the fixes they surfaced:
lower-third exit-length note, block-adaptation framing on the anatomy
technique slot, code-typing per-character wording, caption-component
demo-content note, map determinism/merge-at-source notes, device-mockup
demo-UI expectation, variables img clarification. Embeds 29 unedited
renders next to their prompts (HeyGenVerse-hosted), including a
default-vs-overridden pair demonstrating variables.

Adds 18 pages completing the Prompt Guide expansion (phases 2-4): six
video-type pages seeded by the verified example prompts, and twelve
feature pages giving prompting guidance for surfaces the docs implied
but never covered (transitions, caption styles, overlays, code blocks,
data/maps, VFX, rendering/output, editing existing videos, media/audio,
variables, runtimes/3D, design systems). All block/component/skill names
grounded against the catalog and skills; render pairing deferred.

Splits guides/prompting into a Prompt Guide nav group (overview + Fundamentals
+ Making it look good, 11 pages) with a redirect from the old URL. Applies
research-validated upgrades: beat content formula, before/after prompt rewrites
with engine rationale, single-variable iteration moves, absolute-target
calibration, camera/depth/pacing vocabulary, prerequisites gate.

Documentation-only updates surfaced by the prompt-guide validation
campaign. The behavior fixes from the same campaign are in a separate
PR (pipeline fixes); Tier 3 block bugs are tracked in #2107.
- hyperframes-core SKILL.md: new "First-pass lint gotchas" subsection —
the root composition element must carry data-start="0"
(root_composition_missing_data_start), and initial states belong in
gsap.fromTo, never a CSS transform paired with a GSAP tween on the
same property (gsap_css_transform_conflict). Both were guaranteed
first-build lint failures for agents writing compositions cold.
- media-use SKILL.md: "Weak local-model defaults" row corrected — local
Kokoro TTS is the free default with HeyGen as the paid upsell (was
described backwards), and bg-removal runs via the hyperframes CLI.
- docs/concepts/compositions.mdx: document that data-composition-src
paths resolve relative to the project root, not the referencing file.
- gsap-transforms-and-perf.md: runtime-created SVG (createElementNS)
has no reliable center pivot — draw geometry at local (0,0) inside a
positioning <g> so scale/rotation pivot on the shape's middle.
