## Goal

Deploy a pattern to a local dev server, verify it works via CLI (handler
testing) and browser (UI testing), and produce a structured test report against
acceptance criteria.

## Inputs

You will be told:

- **Pattern path**: Directory containing the pattern source files
- **Acceptance criteria**: Either a spec.md path or inline criteria to verify
- **Report output path**: Where to write the test report (optional)
- **Notes path**: Where to maintain your working journal (optional)

You may also be told:
- A piece ID if the pattern is already deployed
- A port offset or API URL for the dev servers
- A space name to deploy into

## Skills to Load

Load these skills at the start of your workflow:

1. `Skill("cf")` — for deploying, inspecting, and calling handlers
2. `Skill("agent-browser")` — for browser-based UI testing

Also read:

- `docs/common/ai/manual-testing-guide.md`

## Workflow

### 1. Ensure Local Dev Servers Are Running

Check if servers are running, and start/restart if needed:

```bash
./scripts/check-local-dev.sh || ./scripts/restart-local-dev.sh --force
```

If a port offset is specified (e.g. for factory runs), pass it:

```bash
./scripts/restart-local-dev.sh --port-offset=200 --force
```

Default URLs (no offset): Toolshed http://localhost:8000, Shell http://localhost:5173

### 2. Deploy the Pattern

If no piece ID is provided, deploy the pattern:

```bash
deno task cf piece new {pattern-path}/main.tsx \
  --identity claude.key \
  --api-url {api-url} \
  --space {space-name}
```

Save the piece ID from the output.

### 3. CLI Verification (call -> step -> inspect)

Test each handler via the CLI. **Always run `piece step` after `piece call`** —
without it, computed values remain stale.

```bash
# Example: test addCard handler
deno task cf piece call --piece {ID} addCard '{"columnIndex": 0, "title": "Test"}' \
  --identity claude.key --api-url {api-url} --space {space-name}
deno task cf piece step --piece {ID} \
  --identity claude.key --api-url {api-url} --space {space-name}
deno task cf piece inspect --piece {ID} \
  --identity claude.key --api-url {api-url} --space {space-name}
```

For each handler in the spec:

1. Call it with valid input
2. Step to process
3. Inspect to verify state changed correctly
4. Call it with edge-case input (empty strings, out-of-bounds indices)
5. Step and inspect to verify edge cases are handled

### 4. Browser Verification (agent-browser)

**IMPORTANT: Clear the browser profile before testing.** The headless browser
uses a persistent profile at `/tmp/cf-browser-profile` that may contain cached
JavaScript from a previous dev server session (possibly running at a different
port). Stale cached JS will cause the browser to silently fail to connect to
the correct API. Always run this before opening:

```bash
# Close any existing browser and clear stale cache
agent-browser close 2>/dev/null
rm -rf /tmp/cf-browser-profile
```

Then open the pattern in the browser. Use `--headed` if a human is watching
(interactive factory run), or headless for unattended runs:

```bash
# Interactive (human watching):
agent-browser --headed open {api-url}/{space-name}/{piece-id}

# Headless (unattended / default):
agent-browser open {api-url}/{space-name}/{piece-id}
```

Default to headless. Only use `--headed` if the orchestrator prompt explicitly
says the run is interactive or a human is watching.

Then test each acceptance criterion from the spec:

```bash
# Get interactive elements
agent-browser snapshot -i

# Interact with elements using refs
agent-browser fill @e1 "New card title"
agent-browser click @e2

# Re-snapshot after interactions (refs are invalidated)
agent-browser snapshot -i

# Take screenshots at key states
agent-browser screenshot

# Check for expected text
agent-browser get text @e3
```

**Key rules:**

- Always re-snapshot after any interaction that changes the page
- Use `agent-browser wait --load networkidle` after actions that trigger server
  communication
- Take screenshots before and after significant state changes
- Use `--headed` mode only for interactive runs where a human is watching

### 5. Runtime Debugging (when things go wrong)

When the UI doesn't behave as expected, use the runtime inspection utilities
via `agent-browser eval`. These are available on `globalThis.commonfabric` in the
browser. Full reference: `docs/development/debugging/console-commands.md`.

**Read cell values** (verify what data the piece actually holds):

```bash
# Read the full output of the current piece
agent-browser eval "(async () => {
  const v = await commonfabric.readCell();
  return JSON.stringify(v).slice(0, 500);
})()"

# Read a specific field
agent-browser eval "(async () => {
  const v = await commonfabric.readArgumentCell({ path: ['items'] });
  return JSON.stringify(v).slice(0, 500);
})()"
```

**Inspect the VDOM tree** (verify what's actually rendered):

```bash
agent-browser eval "(async () => {
  await commonfabric.vdom.dump();
  return 'dumped to console';
})()"
```

**Detect non-idempotent computations** (if UI is churning / high CPU):

```bash
agent-browser eval "(async () => {
  const r = await commonfabric.detectNonIdempotent(5000);
  return JSON.stringify({ nonIdempotent: r.nonIdempotent.length, cycles: r.cycles.length, busyTime: r.busyTime });
})()"
```

**Check for action schema mismatches** (if handlers seem to do nothing):

```bash
agent-browser eval "JSON.stringify(commonfabric.getLoggerFlagsBreakdown())"
```

**Subscribe to cell updates** (watch values change during interaction):

```bash
agent-browser eval "window._cancel = commonfabric.subscribeToCell()"
agent-browser click @e5
agent-browser console   # Check for "[debug] cell update" entries
agent-browser eval "window._cancel()"
```

Use these tools to diagnose issues before reporting them, and include the
diagnostic output in the test report's "Issues Found" section.

### 6. Write Test Report

Write the report to the provided output path with this structure:

```markdown
# Manual Test Report: {Pattern Name}

**Piece ID**: {id} **Space**: {space} **API URL**: {api_url}
**Date**: {date}

## CLI Verification

For each handler tested:

- **{handlerName}**: PASS/FAIL — {what was tested and result}

## Browser Verification

For each acceptance criterion from the spec:

- [ ] {criterion text} — PASS/FAIL — {how it was verified}

## Screenshots

- {description}: {screenshot path}

## Issues Found

- {issue description, severity, steps to reproduce}

## Summary

{overall assessment: all criteria pass / N criteria fail / blocked by issue}
```

### 7. Working Notes

Throughout your work, maintain freeform notes at the provided notes path.
Record:

- Server startup results
- Deploy output (piece ID, URL)
- Each CLI call and its result
- Browser interaction sequence and observations
- Any issues or unexpected behavior
- Screenshots taken and what they show
