-# Agent Guidelines for ubmit.dev
-
-## Commands
-
-- **Dev**: `pnpm run dev` (starts at localhost:4321)
-- **Build**: `pnpm run build` (runs astro check + build)
-- **Format**: `pnpm run format` (Prettier with Astro/Tailwind plugins)
-- **Type Check**: `pnpm exec astro check`
-- **Visual Tests**: `pnpm run test` (Playwright visual regression tests)
-- **Visual Tests UI**: `pnpm run test:ui` (Interactive Playwright UI mode)
-- **Update Snapshots**: `pnpm run test:update` (Update visual regression baselines after intentional UI changes)
-
-## Code Style
-
-- **TypeScript**: Strict mode, strict null checks enabled
-- **Imports**: Named exports preferred (e.g., `export const SITE_TITLE`)
-- **Formatting**: Auto-formatted via Prettier (prettier-plugin-astro, prettier-plugin-tailwindcss)
-- **Astro Components**: Use frontmatter (`---`) for imports and logic; keep markup semantic
-- **Types**: Explicit types via Zod schemas for content collections; leverage Astro's built-in types
-
-## Styling
-
-- **Tailwind**: Utility-first; use `cn()` helper from `src/utils.ts` for conditional classes
-- **Colors**: Custom gray scale (100-1200) via Radix UI Colors (`--gray-1` to `--gray-12`)
-- **Typography**: Custom fonts (Commit Mono for mono, Work Sans for sans)
-- **Dark Mode**: Handled via CSS `prefers-color-scheme`
+# Agent Guide — ubmit.dev
+
+## Comms
+- be extremely concise, drop grammar if needed
+
+## Commands (pnpm)
+- dev: `pnpm run dev` (localhost:4321)
+- build: `pnpm run build` (astro check + build)
+- format: `pnpm run format`
+- typecheck: `pnpm exec astro check`
+- visual tests: `pnpm run test`
+- visual tests UI: `pnpm run test:ui`
+- update snapshots: `pnpm run test:update`
+
+## Stack + tools
+- package mgr: pnpm
+- github: gh
+- web automation: `agent-browser` (see `agent-browser --help`)
+- frontend tasks: use `/frontend-design`
+- framework: Astro (SSG sites), React + TanStack Start if app needed
+
+## Code style
+- TS strict, no `any`, no default exports, inline `export`
+- avoid new abstractions unless needed; prefer clear names over comments
+- avoid helpers for trivial expressions; avoid `useEffect` unless required
+- no `try/catch` unless necessary
+- file names: kebab-case for `.ts`/`.tsx`/`.jsx`
+- Astro: use frontmatter (`---`), keep markup semantic
+- formatting: Prettier (astro + tailwind plugins)
+
+## UI + styling
+- Tailwind v4 only; use built-ins; rare globals; use `cn()` in `src/utils.ts`
+- colors: Radix gray scale `--gray-1`…`--gray-12`
+- fonts: Commit Mono (mono), Work Sans (sans)
+- dark mode: `prefers-color-scheme`
+- UI lib: project DS first; else `shadcn/ui` w/ Base UI
 
 ## Content
-
-- Blog posts in `src/content/blog/` as MDX/Markdown with frontmatter (title, description, pubDate, etc.)
-- Validate using Zod schema in `src/content/config.ts`
-
-## Testing & CI
-
-- **Visual Regression**: Run manually before deploys (`pnpm run test`)
-- **Snapshots**: Platform-specific (`*-chromium-darwin.png` for macOS)
-- **CI Jobs**: lint-and-format, type-check, build
-- **Updating Snapshots After UI Changes**:
-  1. Run `pnpm run build` (snapshots test against built site)
-  2. Run `pnpm run test:update`
-  3. Commit the updated snapshots in `tests/visual.spec.ts-snapshots/`
-
-## Landing the Plane (Session Completion)
-
-**When ending a work session**, you MUST complete ALL steps below. Work is NOT complete until `git push` succeeds.
-
-**MANDATORY WORKFLOW:**
-
-1. **File issues for remaining work** - Create tasks for anything that needs follow-up
-2. **Run quality gates** (if code changed) - Tests, linters, builds
-3. **Update issue status** - Close finished work, update in-progress items
-4. **PUSH TO REMOTE** - This is MANDATORY:
-
-   ```bash
-   git pull --rebase
-   bd sync
-   git push
-   git status  # MUST show "up to date with origin"
-   ```
-
-5. **Clean up** - Clear stashes, prune remote branches
-6. **Verify** - All changes committed AND pushed
-7. **Hand off** - Provide context for next session
-
-**CRITICAL RULES:**
-
-- Work is NOT complete until `git push` succeeds
-- NEVER stop before pushing - that leaves work stranded locally
-- NEVER say "ready to push when you are" - YOU must push
-- If push fails, resolve and retry until it succeeds
+- blog: `src/content/blog/` (MD/MDX + frontmatter)
+- validate via Zod in `src/content/config.ts`
+
+## Tests + CI
+- CI jobs: lint-and-format, type-check, build
+- visual snapshots: `tests/visual.spec.ts-snapshots/` (`*-chromium-darwin.png`)
+- snapshot update flow:
+  1) `pnpm run build`
+  2) `pnpm run test:update`
+  3) commit snapshots
+
+## Git
+- commits: Conventional Commits, small + intentional
+- branches: prefix `gui/`
