Voiceover

Skill: voiceover

The voice-over is the spec. Instead of a PRD, a feature starts as the demo narration the user would record if the feature had already shipped. This skill owns the whole journey: script → worktree → build → fraimz → PR.

The contract: no code until the script is approved.

Phase 1 — Align on words (no code)

1. Take the feature in a sentence. Ask only what you need to narrate a demo of it.
2. Draft the script. Write the voice-over end to end — one numbered paragraph per frame, 4–8 frames for most features. Spoken style, present tense, the end user as protagonist. Describe what the viewer sees and why it matters, never implementation. If a frame is hard to narrate, the feature (or the frame) is wrong — say so and reshape it.
3. Iterate on words, not code. State the script back and revise with the user until they would actually record it. This conversation is the review that used to happen on a PRD.

Phase 2 — Start clean (fresh worktree)

On approval, set up an isolated workspace so the user's checkout stays untouched:

git fetch origin dev
git worktree add ../_worktrees/openwork-<flow-id> -b feat/<flow-id> origin/dev

Then, inside the worktree:

4. Land the script at evals/voiceovers/<flow-id>.md: a title, optional context prose, then the numbered frame paragraphs. From this point the file is what the code gets held to — the runner fails any flow whose narration drifts from it.
5. Scaffold the flow. pnpm fraimz scaffold <flow-id> generates evals/flows/<flow-id>.flow.mjs with one ctx.prove stub per paragraph, narration pre-wired via loadVoiceoverParagraphs. Do not renumber or reword paragraphs after this without re-approval.

Phase 3 — Build until the demo holds

6. Build the feature. The orchestrator decomposes the work and delegates the coding to the executor subagent; the fraimz loop (see the fraimz skill) is how the orchestrator verifies each round — drive the demo against the real app, repair, and re-run until every frame passes.

Phase 4 — Ship (PR with the proof on it)

7. Open the PR and post the proof. From the worktree:

git push -u origin feat/<flow-id>
gh pr create --base dev --fill
pnpm fraimz --flow <flow-id> --pr   # posts the frame-by-frame proof as a PR comment

The PR review is the demo review: verdict, claims, voiceovers, and assertions, frame by frame.

Script format

# <flow-id> — <one-line claim>

Optional context prose (not narrated).

1. First frame narration, one or two spoken sentences.

2. Second frame narration.

Only numbered paragraphs become frames. Keep each to one or two sentences a human could speak over the screen while it shows exactly that state.

Source of truth

• evals/runner/voiceover.mjs — parser, drift check, scaffolder.
• evals/voiceovers/voiceover-first-dx.md — the reference script (this workflow demoing itself, worktree and PR included).
• The fraimz skill — the validate/repair/verdict loop inside Phase 3.
