-description: Answer questions about the Effect framework
----
-
-# Effect
-
-This codebase uses Effect, a framework for writing typescript.
-
-## How to Answer Effect Questions
-
-1. Clone the Effect repository: `https://github.com/Effect-TS/effect-smol` to
-   `.opencode/references/effect-smol` in this project NOT the skill folder.
-2. Use the explore agent to search the codebase for answers about Effect patterns, APIs, and concepts
-3. Provide responses based on the actual Effect source code and documentation
-
-## Guidelines
-
-- Always use the explore agent with the cloned repository when answering Effect-related questions
-- Reference specific files and patterns found in the Effect codebase
-- Do not answer from memory - always verify against the source

 - Keep things in one function unless composable or reusable
 - Avoid `try`/`catch` where possible
 - Avoid using the `any` type
+- Prefer single word variable names where possible
 - Use Bun APIs when possible, like `Bun.file()`
 - Rely on type inference when possible; avoid explicit type annotations or interfaces unless necessary for exports or clarity
 - Prefer functional array methods (flatMap, filter, map) over for loops; use type guards on filter to maintain type inference downstream
 
+### Naming
+
+Prefer single word names for variables and functions. Only use multiple words if necessary.
+
+### Naming Enforcement (Read This)
+
+THIS RULE IS MANDATORY FOR AGENT WRITTEN CODE.
+
+- Use single word names by default for new locals, params, and helper functions.
+- Multi-word names are allowed only when a single word would be unclear or ambiguous.
+- Do not introduce new camelCase compounds when a short single-word alternative is clear.
+- Before finishing edits, review touched lines and shorten newly introduced identifiers where possible.
+- Good short names to prefer: `pid`, `cfg`, `err`, `opts`, `dir`, `root`, `child`, `state`, `timeout`.
+- Examples to avoid unless truly required: `inputPID`, `existingClient`, `connectTimeout`, `workerPath`.
+
+```ts
+// Good
+const foo = 1
+function journal(dir: string) {}
+
+// Bad
+const fooBar = 1
+function prepareJournal(dir: string) {}
+```
+
 Reduce total variable count by inlining when a value is only used once.

+
+## Test Structure
+
+All tests live in `packages/app/e2e/`:
+
+```
+e2e/
+├── fixtures.ts       # Test fixtures (test, expect, gotoSession, sdk)
+├── actions.ts        # Reusable action helpers
+├── selectors.ts      # DOM selectors
+├── utils.ts          # Utilities (serverUrl, modKey, path helpers)
+└── [feature]/
+    └── *.spec.ts     # Test files
+```
+
+## Test Patterns
+
+### Basic Test Structure
+
+```typescript
+import { test, expect } from "../fixtures"
+import { promptSelector } from "../selectors"
+import { withSession } from "../actions"
+
+test("test description", async ({ page, sdk, gotoSession }) => {
+  await gotoSession() // or gotoSession(sessionID)
+
+  // Your test code
+  await expect(page.locator(promptSelector)).toBeVisible()
+})
+```
+
+### Using Fixtures
+
+- `page` - Playwright page
+- `sdk` - OpenCode SDK client for API calls
+- `gotoSession(sessionID?)` - Navigate to session
+
+### Helper Functions
+
+**Actions** (`actions.ts`):
+
+- `openPalette(page)` - Open command palette
+- `openSettings(page)` - Open settings dialog
+- `closeDialog(page, dialog)` - Close any dialog
+- `openSidebar(page)` / `closeSidebar(page)` - Toggle sidebar
+- `waitTerminalReady(page, { term? })` - Wait for a mounted terminal to connect and finish rendering output
+- `runTerminal(page, { cmd, token, term?, timeout? })` - Type into the terminal via the browser and wait for rendered output
+- `withSession(sdk, title, callback)` - Create temp session
+- `withProject(...)` - Create temp project/workspace
+- `sessionIDFromUrl(url)` - Read session ID from URL
+- `slugFromUrl(url)` - Read workspace slug from URL
+- `waitSlug(page, skip?)` - Wait for resolved workspace slug
+- `trackSession(sessionID, directory?)` - Register session for fixture cleanup
+- `trackDirectory(directory)` - Register directory for fixture cleanup
+- `clickListItem(container, filter)` - Click list item by key/text
+
+**Selectors** (`selectors.ts`):
+
+- `promptSelector` - Prompt input
+- `terminalSelector` - Terminal panel
+- `sessionItemSelector(id)` - Session in sidebar
+- `listItemSelector` - Generic list items
+
+**Utils** (`utils.ts`):
+
+- `modKey` - Meta (Mac) or Control (Linux/Win)
+- `serverUrl` - Backend server URL
+- `sessionPath(dir, id?)` - Build session URL
+
+## Code Style Guidelines
+
+### Imports
+
+Always import from `../fixtures`, not `@playwright/test`:
+
+```typescript
+// ✅ Good
+import { test, expect } from "../fixtures"
+
+// ❌ Bad
+import { test, expect } from "@playwright/test"
+```
+
+### Naming Conventions
+
+- Test files: `feature-name.spec.ts`
+- Test names: lowercase, descriptive: `"sidebar can be toggled"`
+- Variables: camelCase
+- Constants: SCREAMING_SNAKE_CASE
+
+### Error Handling
+
+Tests should clean up after themselves. Prefer fixture-managed cleanup:
+
+```typescript
+test("test with cleanup", async ({ page, sdk, gotoSession }) => {
+  await withSession(sdk, "test session", async (session) => {
+    await gotoSession(session.id)
+    // Test code...
+  }) // Auto-deletes session
+})
+```
+
+- Prefer `withSession(...)` for temp sessions
+- In `withProject(...)` tests that create sessions or extra workspaces, call `trackSession(sessionID, directory?)` and `trackDirectory(directory)`
+- This lets fixture teardown abort, wait for idle, and clean up safely under CI concurrency
+- Avoid calling `sdk.session.delete(...)` directly
+
+### Timeouts
+
+Default: 60s per test, 10s per assertion. Override when needed:
+
+```typescript
+test.setTimeout(120_000) // For long LLM operations
+test("slow test", async () => {
+  await expect.poll(() => check(), { timeout: 90_000 }).toBe(true)
+})
+```
+
+### Selectors
+
+Use `data-component`, `data-action`, or semantic roles:
+
+```typescript
+// ✅ Good
+await page.locator('[data-component="prompt-input"]').click()
+await page.getByRole("button", { name: "Open settings" }).click()
+
+// ❌ Bad
+await page.locator(".css-class-name").click()
+await page.locator("#id-name").click()
+```
+
+### Keyboard Shortcuts
+
+Use `modKey` for cross-platform compatibility:
+
+```typescript
+import { modKey } from "../utils"
+
+await page.keyboard.press(`${modKey}+B`) // Toggle sidebar
+await page.keyboard.press(`${modKey}+Comma`) // Open settings
+```
+
+### Terminal Tests
+
+- In terminal tests, type through the browser. Do not write to the PTY through the SDK.
+- Use `waitTerminalReady(page, { term? })` and `runTerminal(page, { cmd, token, term?, timeout? })` from `actions.ts`.
+- These helpers use the fixture-enabled test-only terminal driver and wait for output after the terminal writer settles.
+- After opening the terminal, use `waitTerminalFocusIdle(...)` before the next keyboard action when prompt focus or keyboard routing matters.
+- This avoids racing terminal mount, focus handoff, and prompt readiness when the next step types or sends shortcuts.
+- Avoid `waitForTimeout` and custom DOM or `data-*` readiness checks.
+
+### Wait on state
+
+- Never use wall-clock waits like `page.waitForTimeout(...)` to make a test pass
+- Avoid race-prone flows that assume work is finished after an action
+- Wait or poll on observable state with `expect(...)`, `expect.poll(...)`, or existing helpers
+- Prefer locator assertions like `toBeVisible()`, `toHaveCount(0)`, and `toHaveAttribute(...)` for normal UI state, and reserve `expect.poll(...)` for probe, mock, or backend state
+- Prefer semantic app state over transient DOM visibility when behavior depends on active selection, focus ownership, or async retry loops
+- Do not treat a visible element as proof that the app will route the next action to it
+- When fixing a flake, validate with `--repeat-each` and multiple workers when practical
+
+### Add hooks
+
+- If required state is not observable from the UI, add a small test-only driver or probe in app code instead of sleeps or fragile DOM checks
+- Keep these hooks minimal and purpose-built, following the style of `packages/app/src/testing/terminal.ts`
+- Test-only hooks must be inert unless explicitly enabled; do not add normal-runtime listeners, reactive subscriptions, or per-update allocations for e2e ceremony
+- When mocking routes or APIs, expose explicit mock state and wait on that before asserting post-action UI
+- Add minimal test-only probes for semantic state like the active list item or selected command when DOM intermediates are unstable
+- Prefer probing committed app state over asserting on transient highlight, visibility, or animation states
+
+### Prefer helpers
+
+- Prefer fluent helpers and drivers when they make intent obvious and reduce locator-heavy noise
+- Use direct locators when the interaction is simple and a helper would not add clarity
+- Prefer helpers that both perform an action and verify the app consumed it
+- Avoid composing helpers redundantly when one already includes the other or already waits for the resulting state
+- If a helper already covers the required wait or verification, use it directly instead of layering extra clicks, keypresses, or assertions
+
+## Writing New Tests
+
+1. Choose appropriate folder or create new one
+2. Import from `../fixtures`
+3. Use helper functions from `../actions` and `../selectors`
+4. When validating routing, use shared helpers from `../actions`. Workspace URL slugs can be canonicalized on Windows, so assert against canonical or resolved workspace slugs.
+5. Clean up any created resources
+6. Use specific selectors (avoid CSS classes)
+7. Test one feature per test file
+
+## Local Development
+
+For UI debugging, use:
+
+```bash
+bun test:e2e:ui
+```
+
+This opens Playwright's interactive UI for step-through debugging.
