I want a small todo app. Add todos, tick them off, filter open and done. Browser only, no backend.

Read .spec-first/memory/MEMORY.md

Read src/main.ts

It's an empty Vite starter, and I'll use TypeScript and Vitest as you prefer. Should todos survive a reload?

Yes, localStorage is fine.

/spec-first:create-spec

Write 2026-10-27-7b2d-todos-first-version.yaml

Here is the spec. Shall I put it on its own branch?

Looks right, go.

Bash git worktree add -b spec/2026-10-27-7b2d …

Spec 2026-10-27-7b2d is on its own branch: 3 steps, 3 done criteria.

/spec-first:review-spec

Bash check-evidence.py evidence resolves: 1 spec

Agent Review spec 2026-10-27-7b2d fresh context

Edit 2026-10-27-7b2d-todos-first-version.yaml

BUILD WITH CUTS. Drag to reorder is out, a check for empty titles is in. Both applied.

/spec-first:apply-spec

Plan: the store first, then the list, then the tests. Go?

Go.

Write src/todos.ts

Write src/TodoList.ts

Write src/todos.test.ts

Bash npm test 9 passed

Write .spec-first/decisions/2026-10-27-7b2d.yaml

Built and tested. One decision on record: localStorage over IndexedDB, because a few hundred todos fit easily.

/spec-first:deliver-spec

Bash git commit -m "feat: a first todo app (2026-10-27-7b2d)" gate: build, test passed

Bash gh pr create #12

Bash npm run dev localhost:5173

The gate passed and pull request #12 is open. The app runs on localhost:5173.
