feat(cli): shared TTS/BGM auth preflight + caption and skill-workflow fixes

[WaterrrForever]

What

Six commits off current main, grouped as one branch. The headline is a shared sign-in
preflight for TTS & BGM in the CLI; the rest are caption-rendering and video-workflow
robustness fixes that ride along.

Commit	Scope
feat(auth) onboarding-first auth status + shared TTS/BGM preflight	new audio/providers + auth/status-guidance modules; doctor + tts/python wired in
fix(hyperframes-media) enforce sign-in preflight on standalone BGM/TTS	standalone BGM/TTS now gate on sign-in before running
fix(captions) embed brand fonts whose files use separators	font files with spaces/_/- in the name now embed across all three caption skills
fix handle caption skin workflow	linter (core + cli) recognizes the caption-skin path instead of flagging it
feat(pr-to-video) scale recommended length to PR change size	recommended video length now tracks the size of the PR's diff
docs(skills) simplify the finalize step	trimmed the finalize step across the video workflows

Why

• Auth preflight — standalone BGM/TTS could start work before failing on a missing
  sign-in, wasting a run. Centralizing the check (and making auth status onboarding-first)
  surfaces the requirement up front, with one shared path used by every audio workflow.
• Caption font embedding — brand fonts whose filenames contain separators were not
  matched and silently dropped, so captions fell back to a default face.
• Caption-skin workflow — the linter flagged the caption-skin path as invalid, blocking
  an otherwise-valid render.
• pr-to-video length — a fixed recommended length over/under-shot for PRs of very
  different sizes; scaling to the change set gives a more sensible default.

How

• packages/cli — new audio/providers.ts (shared provider/preflight resolution) and
  commands/auth/status-guidance.ts (onboarding-first guidance); auth status, doctor,
  and tts/python consume them. tts/synthesize slims down to the shared path.
• Caption scripts — captions.mjs + lib/tokens.mjs in faceless-explainer,
  pr-to-video, and product-launch-video updated identically to match separator-bearing font
  filenames and embed them.
• Linter — core/src/lint/context.ts + cli/src/utils/lintProject.ts recognize the
  caption-skin workflow.
• Skills — pr-to-video/SKILL.md scales recommended length; finalize steps simplified
  across the video-workflow SKILLs.

Test plan

• bun run test — new units: audio/providers.test.ts, auth/status.test.ts,
  lintProject.test.ts, hyperframeLinter.test.ts
• Build, lint (oxlint), format (oxfmt --check) clean on changed files
• Manual: standalone BGM/TTS without sign-in stops at preflight; auth status shows
  onboarding guidance; captions embed a separator-named brand font; caption-skin render
  passes the linter

Notes

The commits are independent and bundled as one branch — happy to split by scope if you'd
rather review the auth work separately from the caption/skill fixes.

Review: feat(cli): shared TTS/BGM auth preflight + caption and skill-workflow fixes

This is a big bundle — 6 logical changes across 38 files. Reviewing each scope independently.

---

1. Auth preflight (audio/providers.ts, auth/status-guidance.ts, auth/status.ts, tts/python.ts, doctor.ts)

Architecture is clean. The decide/gather split is well-designed — pure decideVoice/decideMusic functions take facts, return engine readiness; gather* does the I/O. This makes the pure logic unit-testable without spawning Python.

Good decisions:

• hasPythonModules uses importlib.util.find_spec (fast, doesn't import torch) instead of import — correct for a preflight.
• gatherVoiceFacts / gatherMusicFacts short-circuit when HeyGen is configured — no Python probes needed.
• findPython exported from tts/python.ts and reused in synthesize.ts — clean extraction, no duplication.
• detectUnconfiguredContext correctly treats agent runtimes as interactive (they relay output to users) but CI as non-interactive.
• buildUnconfiguredJson gives skills a machine-readable path via --json.

Test coverage solid — providers.test.ts (10 cases for the decide functions) and status.test.ts (testing guidance lines, JSON output, engine readiness display, non-interactive terse mode).

2. Caption font embedding fix (captions.mjs × 3, tokens.mjs × 3)

This is the highest-value bug fix in the PR. The brandFontFaces function was silently dropping fonts whose filenames contained underscores or hyphens because fam.replace(/\s+/g, "") only stripped whitespace while the files used _ / - as word separators.

The fix (norm = s => s.toLowerCase().replace(/[^a-z0-9]/g, "")) strips ALL non-alphanumerics on both sides of the match. Three additional improvements:

1. claimed set prevents a shorter family from stealing a longer one's files (e.g. "TT Norms Pro" vs "TT Norms Pro Mono").
2. Longest-key-first sort ensures the more specific family matches first.
3. weightOf reorder — semibold/demibold checked before bold because "demibold" contains "bold". The old order misclassified demibold as 700.

The warning when no font files match is a great DX add — surfaces the root cause at build time instead of a disconnected lint error two steps later.

Same fix applied identically across faceless-explainer, pr-to-video, and product-launch-video — the scripts are currently duplicated per skill. Not ideal (a shared module would be better), but that's pre-existing structure, not this PR's problem.

3. Caption skin path migration (build-frame.mjs × 3, captions.mjs × 3, SKILL.md × 5)

Moves caption-skin.html from the project root to .hyperframes/caption-skin.html. The captions.mjs scripts check .hyperframes/ first, then fall back to the legacy root path — backward compatible. All SKILL.md docs updated consistently.

4. Linter: comment stripping + caption-skin exclusion

• context.ts: rawSource.replace(/<!--[\s\S]*?-->/g, "") strips HTML comments before the template-match regex runs. This prevents <!-- <template> --> in a comment from being matched as the template boundary. The new test case pins this exactly.
• lintProject.ts: Skips caption-skin.html in the multiple-root-compositions check. Test added.

Both are small, correct, well-tested.

5. pr-to-video length scaling

Nice improvement — scaling recommended video length to the PR's actual change size (+/- lines, nudged by file count) instead of a fixed 60-90s guess. The tier table is sensible.

6. Skill doc updates (finalize simplification, font guidance, preflight gates)

Every video-creation skill now shows hyperframes auth status as a decision gate in Step 0. Frame-worker docs now explicitly warn against naming fonts without shipped files. Finalize steps simplified across the board. All consistent.

---

CI status

Format check is failing. The Preflight (lint + format) jobs are red across multiple pipelines. Worth fixing before merge — likely just a formatting pass on the new files.

The CodeQL, player-perf, preview-regression, and regression failures look unrelated (skipping/config-gated, not actual test failures), but Format is a real blocker.

Minor observations (non-blocking)

1. tokens.mjs color regex — the new regex (?:"([^"]+)"|'([^']+)'|(#...)) with m[2] ?? m[3] ?? m[4] is more robust than the old ["']? approach, but it also now strips trailing # comments via (?:#.*)?$. Make sure no color values legitimately contain # after the value (unlikely for CSS colors, but worth noting).

2. parseFonts fallback chain — Adding h1, h2, title, hero as display-font role lookups makes sense. Just noting that hero is quite generic — could match a non-font "hero" role key in some token schemas. Low risk since it's a ?? chain (only used when nothing more specific matches).

LGTM on the code — fix the Format CI failure and this is ready to go.

— Review by Miga

[jrusso1020]

Read the auth-preflight surface + the caption-fix logic + the linter context change in full. 38 files / +928/-124 is past one-pass review so the skill .md changes + the 3 SKILL.md docs are scope-down samples. Posting as COMMENT — per the customer-partner-PR discipline (Miao's WaterrrForever GH handle is the same allowlisted contributor as the prior PRs in this batch), stamp eligibility routes through James. Also not stampable as-is: 9 CI checks are RED, including 2 high-severity CodeQL alerts.

CI red — needs addressing before merge

Check	Status
Format	FAIL
Preflight (lint + format) × 4	FAIL
player-perf	FAIL
preview-regression	FAIL
regression	FAIL
CodeQL	FAIL (2 high-severity alerts)

Same shape as HF#1665 had at draft time. Probably:

• Format / Preflight × 4 → run bun run format on the 38 changed files.
• player-perf / preview-regression / regression → either an intentional baseline drift (new caption/linter behavior shifts a fixture) requiring a regression:update, OR an unintended regression worth investigating per-job.
• CodeQL → covered below.

Two high-severity CodeQL alerts both on context.ts:32 — same shape #1635 already learned from

CodeQL flagged the new line in packages/core/src/lint/context.ts:32:

let source = rawSource.replace(/<!--[\s\S]*?-->/g, "");

• js/incomplete-multi-character-sanitization (security_severity: high) — single-pass replace doesn't handle nested comments. A payload like <!--<!---->--> leaves a dangling start-marker after one pass.
• js/polynomial-redos (security_severity: high) — the regex can be slow on strings starting with <!-- with many repetitions.

This is the same shape HF#1635 (cfdc21312) already fixed in captions.mjs:227: the fix there was to replace the single-pass regex with a fixpoint loop:

while (out.includes("<!--")) out = out.replace(/<!--[\s\S]*?-->/g, "");

The same fix applies here. Miga's review praised the linter comment-stripping logic but didn't catch that it's the regression #1635 already had + fixed elsewhere. The fixpoint-loop pattern needs to land in context.ts to match.

Additive findings beyond Miga's pass

Three quick observations Miga's review summary didn't surface:

1. weightOf ordering bug fix in captions.mjs (silently included): the pre-fix order had if (/bold/.test(s)) return 700 BEFORE if (/semibold|demibold/.test(s)) return 600, so "SemiBold" / "DemiBold" matched /bold/ first and got weight 700 (wrong). The new order checks semibold/demibold first. Comment says "before /bold/ — 'demibold' contains 'bold'". Small but real. ✓

2. Skin path migrates to .hyperframes/caption-skin.html (hidden dir) with legacy caption-skin.html fallback. This is a workflow change — Step 2 of each skill that copies the chosen frame-preset's skin needs to write to the new hidden path. Worth confirming the Step-2 code matches (or accept that the legacy fallback covers the transition period). Miga didn't surface this.

3. Skin docstring updated to reflect the hidden path: comment header now says .hyperframes/caption-skin.html (line 18). Body documentation is in sync. ✓

Cross-site applicability check for the new audio/providers.ts helper

Per [[feedback_audit_try_catch_scope_and_cross_site_applicability_on_new_helper_prs]]:

• Consumers within this PR: auth status, doctor, tts/python, tts/synthesize (the slim-down). That's 4 consumers.
• What about render commands? The skill scripts in hyperframes-media/scripts/audio.mjs (the orchestrator) have their own provider resolution. Does the new decide* / gather* get adopted there?
  • The PR body says "Mirrors the resolution order the hyperframes-media skill scripts use." That's parallel implementation, not shared code. Same logic in two places = potential drift surface.
  • Future PR opportunity: lift the CLI-side audio/providers.ts to a shared module the skill scripts can also import. Out of scope for this PR but worth a follow-up note.

The split between decide (pure, unit-testable) and gather (live facts) is clean architecture. Try/catch scope on the gather paths is appropriate — hasPythonModules uses find_spec which is exception-free for the common cases.

Verified Miga's findings

• norm() strips all non-alphanumerics on both sides — verified at captions.mjs:319-320 of the diff. Plus the longest-family-first sort prevents prefix-collision (e.g. "TT Norms Pro" claiming "TT Norms Pro Mono"'s files), tracked via the new claimed: Set deduplicating across the sorted iteration. Two distinct improvements bundled into the same fix. ✓
• Linter comment stripping in context.ts — verified, but flagged for the CodeQL issue above.
• Auth preflight clean decide/gather architecture — verified. The pure decision functions are testable without spawning Python.

Body claims verified

• "6 commits ... bundled as one branch" — verified.
• "captions.mjs + lib/tokens.mjs in faceless-explainer, pr-to-video, and product-launch-video updated identically" — sampled faceless-explainer's captions.mjs diff in full; trust the body for the other two byte-for-byte. Worth a quick diff between the three files at the team-merge moment.
• "auth status, doctor, and tts/python consume them" — verified.

Stamp posture

Same routing as the prior Miao batch — customer-partner-PR, hand-back to <@U08E7PV788Z>. Even without that policy, the 9 CI failures + 2 high-severity CodeQL alerts block stamp under REVIEW_DISCIPLINE rule #1. The two CodeQL alerts in particular should land the same fixpoint-loop pattern that HF#1635 already shipped — that's a known-working precedent.

Review by Jerrai

[jrusso1020]

R2 at 9cae28dffa — Verified the auth update + the two follow-up commits since R1.

R1 blockers addressed

• CodeQL — both high-severity alerts on context.ts:32 now resolved (69270f7368). The fix lifted the comment-stripping into a shared stripHtmlComments(html) utility (linear scan + fixpoint), called from buildLintContext and pointed at by captions.mjs:227 too. Single source of truth across both call sites — better than the per-site fixpoint loop I'd pointed at #1635 for. 0 open CodeQL alerts on this PR now.
• CI checks: 41/41 passing with 10 pending (running for the new HEAD). No remaining failures from the R1 sweep (Format / Preflight / player-perf / regression all clean).

Auth-update commit (9cae28dffa) — well-scoped + truthful

Walked the 13 files. The commit body's three points are exactly the right cuts:

1. heygen auth login is API-key-only, not OAuth — corrects the over-promise in the original copy. The shared-credential fact stays in docs/guides/authentication.mdx (truthful), but the onboarding flow no longer dangles heygen auth login as a parallel "create an account" step alongside hyperframes auth login.
2. npx hyperframes everywhere — correct for first-touch UX. Bare hyperframes isn't on PATH on a fresh machine; npx hyperframes is. All imperatives (status-guidance.ts, error messages in heygen.mjs/tts.mjs, all 5 skill SKILL.md previews, references/{requirements.md,tts.md}) flipped consistently.
3. Drop heygen auth login from skill onboarding — there's no npx heygen, so it was a command-not-found trap. Right call.

The status-guidance UI rewrite is cleaner too — splits OAuth and --api-key into two labeled blocks with the API-key URL (app.heygen.com/settings/api) inline. Tests status.test.ts updated to pin both the positive (npx hyperframes auth login recommended) and negative (heygen auth login no longer surfaced) contracts.

Nothing new to block on

• 5-file scope tight; no drive-bys
• Tests cover both shapes
• Error messages and skill copy fully consistent
• The data-mismatch the commit fixes was a real first-touch UX trap (sign-up → "now go install a separate CLI and run a command that pastes a key")

Worth noting for the next round (not this PR): the heygen-cli OAuth story discussed in the parent thread is still the path to fully unified sign-up across both CLIs. Right now the shared ~/.heygen/credentials story is honest but asymmetric — hyperframes auth login creates accounts via OAuth, heygen auth login doesn't. Closing that asymmetry is a heygen-cli PR, not a HyperFrames one.

Stamp posture: COMMENT only — routing through James per the customer-partner-PR discipline. Code is clean on merit; James decides on stamp.
