Préparer une version majeure pour apple-fm

name: prep-major-release description: Prep apple-fm for a major release — refresh the README so it advertises the current feature set, and review/revise the demo modes (the user captures the screenshots) allowed-tools: Read, Grep, Glob, Bash, Edit, Write

Get apple-fm's public-facing material ready for a release: make the README compelling and accurate to the current feature set, and review the demo modes so the screenshots are the right ones. You do not capture the demos — you prepare everything and hand off; the user runs the capture.

What "ready for release" means

The README and demos are the first thing a prospective user sees. After a batch of changes they drift in two directions: a new headline feature ships but isn't advertised, or a removed feature is still being sold. Both are bugs here. The goal is a README that honestly and compellingly reflects what apple-fm does today.

Steps

1. Establish the current feature set (source of truth = code + requirements).

   • Read docs/3-requirements.md (the FR/NFR table with status markers) and docs/ai/requirements-summary.md. Shipped FR/NFRs are what's advertisable; Partial ones can be mentioned with honest framing; Dropped/Removed ones must not appear in the README.
   • Read the public API (src/index.ts) and the CLI surface (src/cliArgs.ts USAGE) so command/flag examples in the README actually exist.
   • Skim recent history for what changed: git log --oneline -30 and the Hot Sheet completed tickets. Look specifically for added features (new FR, new flag, new export) and removed ones (a feat!/BREAKING CHANGE, a deleted module).

2. Review README.md against that set. Read it top to bottom and check:

   • Headline / tagline still true (e.g. the on-device / no-network claim — if a networked feature was added or removed, this line changes).
   • "Why apple-fm" bullets cover the most important and interesting shipped features. As of this writing those are: on-device & private (no key/cloud/network), one-binary-three-shapes (probe/generate/chat), guaranteed structured output (guided generation), long coherent chat (persistent session + auto-compaction + Esc interrupt), tool calling (permission-gated local read/bash), zero runtime deps, and future-proof (runtime model resolution). Add a bullet for any shipped headline feature that's missing; delete any that no longer ship.
   • CLI / Library examples match real flags and API (no removed flags, no invented ones).
   • Every <img> alt text still describes what the demo shows.
   • Install / platform-support / disclaimer / license still accurate.
   • Tighten prose so it stays compelling and scannable — lead with the benefit, not the mechanism. Don't pad with an imageless section if a bullet does the job.

3. Upgrade the demo tooling (domotion-svg) to the latest, if out of date. The demos are rendered with the domotion CLI from the domotion-svg dev-dependency, so a release should capture on the current renderer. Do this before reviewing/capturing demos so the review reflects what will actually ship.

   • Compare installed vs. latest: npm ls domotion-svg (installed) against npm view domotion-svg version (latest — or, if the npm cache is unwritable in this environment, curl -s https://registry.npmjs.org/domotion-svg | ... reads the dist-tags.latest). If they match, skip the rest of this step.
   • If out of date, bump it: npm install --save-dev domotion-svg@latest (updates package.json + the lockfile).
   • Then re-sync the demo pipeline to the new renderer. scripts/lib/window.mjs and scripts/lib/cast.mjs are pure string transforms keyed off domotion's output shape (a frame is <g class="f f-N">; the cast frame wraps a nested <svg>), and both are pinned by comment to a specific domotion version (search for domotion 0.15 and similar). A domotion upgrade can change that output shape and silently break the window-dressing / title-card compositing.
     • Run npm test — tests/demo.test.ts exercises the transforms and is the first tripwire for shape drift. Fix any breakage in window.mjs / cast.mjs and their tests.
     • Update the version references in the docstrings/comments (scripts/demo.mjs, scripts/lib/*.mjs, and this skill's examples) to the new version so they don't lie about which renderer they target.
     • Because the transform coupling is fragile and demo output is only truly verifiable against the real on-device model (the user's capture step), flag in your hand-off report that domotion was upgraded from X→Y and that the recaptured SVGs should be eyeballed for regressions.

4. Review the demo modes in scripts/demo.mjs (the DEMOS array). Each entry is a { slug, title{eyebrow,headline,subtitle}, cmd, capture } (the chat one is composed turn-by-turn). For each, decide: does it still showcase a current, compelling capability? Consider new / different / fewer:

   • New — a shipped feature with no demo that would demo well. Note that demos run the real on-device model (non-deterministic output), so a good demo is one whose value shows even with varying wording. Be wary of demos that depend on the model reliably doing something specific (e.g. calling a tool on cue) — those make flaky, embarrassing assets. Prefer prose in the README for those.
   • Different — an existing demo's prompt/title/subtitle is stale or undersells the feature; revise the title/cmd/capture text.
   • Fewer — a demo that's redundant or no longer interesting; remove it (and its <img> from the README).
   • Edit scripts/demo.mjs to make these changes. Keep each demo's slug stable unless you intend to rename the output file (then update the README <img src>).
   • If you changed scripts/demo.mjs, run npm test — tests/demo.test.ts covers the pure demo-composition logic (buildChatFrames / parseChatTranscript).

5. Verify the non-capture changes. npm run lint && npm run typecheck && npm test should stay green (README is prose; demo.mjs is covered by demo.test.ts). Fix any breakage before handing off.

6. Hand off the capture — do NOT run it yourself. The demos are captured by npm run demo (build + node scripts/demo.mjs), which runs the real on-device model and drives headless Chromium via domotion. Summarize for the user:

   • what you changed in the README and in the demo modes (added/removed/revised demos),
   • whether you upgraded domotion-svg (from X→Y) — if so, call it out so the user watches the recaptured SVGs for renderer regressions,
   • that they should now run npm run demo to (re)capture all demo SVGs (always all — minor rendering details drift between captures),
   • the capture requirements: macOS 26+ Apple Silicon with the model ready, and that model-loading is blocked by the command sandbox (it surfaces as modelNotReady even though --probe says available) — so the capture must run unsandboxed / in a normal terminal.

   Then stop and let the user capture. (Only run npm run demo yourself if the user explicitly asks you to in this invocation.)

Don't

• Don't bump the project version in package.json. The release flow (npm run release) derives the bump from conventional commits — a feat!: / BREAKING CHANGE: footer yields a major bump automatically. See docs/5-releasing.md. (This is separate from the domotion-svg dev-dependency bump in step 3, which you should do.)
• Don't capture demos unless explicitly asked — that's the user's step (it needs the on-device model + an unsandboxed run).
• Don't invent features. Everything advertised must trace to a Shipped FR/NFR or a real export/flag.

Report

End with: the README edits made (and why), any domotion-svg upgrade (X→Y, plus any window.mjs / cast.mjs transform fixes it required), the demo-mode changes (added / revised / removed, with the reasoning for any new-vs-prose call), the verify result (lint/typecheck/test), and a clear "ready to capture — run npm run demo (unsandboxed)" hand-off line.
