run-oikos

Idempotent driver for the Oikos repo's Next.js 16 (Turbopack) dev server. Paths below are relative to repo root (<unit>/ = oikos repo root).

The agent path: smoke.sh

One script, one command, all paths verified in this container:

.claude/skills/run-oikos/smoke.sh

What it does, in order:

1. Sanity-checks Node ≥ 20 (Next 16 requires it). Bails on the user's shell PATH if node / npm aren't visible (fnm/nvm shells without use activated will trip this).
2. Confirms .env.local exists. If missing, prints a directive to copy .env.local.example or (in worktrees) symlink from the main checkout.
3. Detects the stale-install state: package.json declares @next/bundle-analyzer but node_modules/@next/bundle-analyzer doesn't exist. Symptom from a vanilla next dev: Error: Cannot find module '@next/bundle-analyzer' and dev silently dies. Fix: the script runs npm install automatically when this signature matches.
4. If :3000 is already serving (probably your prior session), reuses it instead of double-launching.
5. Otherwise launches npm run dev via nohup into .claude/skills/run-oikos/.logs/dev-3000.log, then polls the log for Ready in <Nms> with a 60s ceiling. Crashes are surfaced by greppping for Error|EADDRINUSE|Failed to and tailing the log.
6. Smokes three routes that are reliable under Turbopack cold-start: / → 200, /zh-TW → 200, /dashboard → 307. See Gotchas for why /sign-in is intentionally not in the smoke set.
7. Leaves the server running, prints the URL + PID + log path + how to stop it.

To stop:

.claude/skills/run-oikos/smoke.sh --stop

(Or the underlying: lsof -ti :3000 | xargs kill.)

Override port if 3000 is in use by another project:

PORT=3001 .claude/skills/run-oikos/smoke.sh

Prerequisites

• macOS or Linux with Node ≥ 20 (Next 16 requirement). This session ran Node v24.15.0 / npm 11.12.1 on darwin 24.0.0.
• .env.local at the repo root, populated with the Supabase dev project credentials. .env.local.example has the template. The user has a separate oikos prod and oikos-dev dev Supabase project; local npm run dev must talk to the dev one. In worktrees the convention is to symlink rather than copy (ln -s ../../.env.local) so key rotations don't drift.
• A clean :3000 (or set PORT).

Direct invocation: drive the running app

Once smoke.sh returns the server is live, use plain curl to drive routes from an agent:

curl -s -o /dev/null -w "%{http_code}\n" http://localhost:3000/zh-TW
# → 200

# Signed-out user hitting an auth-walled route 307s to the
# locale-aware sign-in path.
curl -sI http://localhost:3000/dashboard | grep -i '^location:'
# → location: /zh-TW/sign-in

# Inspect the rendered HTML of the landing for a chip / glyph change:
curl -s http://localhost:3000/zh-TW | grep -o 'phoneMock[A-Za-z]*'

For visual verification (DOM mutations, screenshots, focus rings), fall through to a real browser at http://localhost:3000/ — the script keeps the server alive in the background for as long as you need it.

Run (human path)

npm install      # if you just pulled / switched node_modules-disturbing branches
npm run dev      # interactive; Ctrl-C to stop

Open http://localhost:3000/ in a browser. Same dev server as the agent path; useful for actual visual inspection.

Gotchas

• Error: Cannot find module '@next/bundle-analyzer' after a branch swap or fresh clone. next.config.ts imports the analyzer unconditionally (gated only by ANALYZE=true for actually running it), so an absent package kills dev too. The script auto-runs npm install when it detects this; if you bypassed the script, run it manually.
• /sign-in 404s on first cold curl under Turbopack. Verified this session: /zh-TW/sign-in and /sign-in both 404 from a fresh next dev even though app/[locale]/sign-in/page.tsx exists. The same route renders 200 once you reach it via the in-app /dashboard → 307 → sign-in redirect chain from a real browser session — Turbopack apparently warms the route through that path but not via a direct curl. Hence the smoke set intentionally skips /sign-in; check it through a browser session if you need it.
• package-lock.json version field drift. The lockfile's "version" was stamped 1.2.4 while package.json was 1.3.0 (release didn't push the lockfile bump). Harmless to dev but will rage npm ci; the v1.3.1 PR fixed it.
• bundle-analyzer adds ~16 packages on first install. Not a bug — they're transitive deps of the analyzer. Worth noting so the npm install output isn't surprising.
• Dev server binds to 0.0.0.0 and prints a LAN URL. If you're driving from another device on the same network, use the 192.168.x.x URL Next prints, not just localhost.
• .env.local is not in any repo lock. Loss of the file (e.g. deleted by accident in a worktree) leaves dev launching but every Supabase call failing. The script catches the missing-file case; it can't catch wrong-but-present keys.

Troubleshooting

Layout

.claude/skills/run-oikos/
  SKILL.md      # this file
  smoke.sh      # the driver (chmod +x)
  .logs/        # gitignored; dev server logs land here

.logs/ is created on first run. Add to .gitignore if you maintain one (this repo doesn't ignore inside .claude/skills/ explicitly).
