# TeamPulse Implementation Plan

> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.

**Goal:** Python script that monitors a Microsoft Teams meeting chat, records who posted in a defined time window, resolves display names to email addresses via profile cards, and generates a sorted Markdown memo.

**Architecture:** Playwright controls a headless Teams Web browser in the background. A polling loop reads new chat messages every 2 seconds. When `!start "Name"` / `!stop` commands are detected (posted by the current user), a time window opens/closes. After the window, profile cards are clicked to resolve emails. A Markdown memo is generated and saved.

**Tech Stack:** Python 3.12, Playwright (sync API), pytest, pytest-mock

## File Map

| File | Responsibility |
|---|---|
| `src/teampulse/models.py` | Shared dataclasses: `ChatMessage`, `AuditEntry`, `AuditWindow` |
| `src/teampulse/memo.py` | Pure function: `AuditWindow → str`, save to file |
| `src/teampulse/resolver.py` | `Resolver` class: cache lookup + browser profile card extraction |
| `src/teampulse/monitor.py` | `Monitor` class: DOM polling, trigger parsing, message collection |
| `src/teampulse/auth.py` | `create_context()`: persistent Playwright session, login detection, read current user |
| `main.py` | Entry point: wire all components, start polling loop |
| `tests/test_memo.py` | Unit tests for memo generation |
| `tests/test_resolver_cache.py` | Unit tests for cache layer (no browser) |

## Task 6: DOM Discovery Script

**Files:**
- Create: `scripts/discover_dom.py`

This task identifies the exact CSS selectors for Teams Web. Run it once with Teams open, inspect output, then update the constants used in Tasks 7 and 8.

- [ ] **Step 1: Create discovery script**

`scripts/discover_dom.py`:

```python
"""Run this script once with a Teams meeting chat open.
It prints DOM info to help identify selectors for messages and profile cards.
Usage: .venv/bin/python scripts/discover_dom.py <teams-chat-url>
"""
import sys
from playwright.sync_api import sync_playwright

URL = sys.argv[1] if len(sys.argv) > 1 else "https://teams.microsoft.com"
SESSION_DIR = str(__import__("pathlib").Path.home() / ".teampulse" / "session")


def main():
    with sync_playwright() as p:
        browser = p.chromium.launch_persistent_context(
            SESSION_DIR,
            headless=False,
            args=["--no-sandbox"],
        )
        page = browser.pages[0] if browser.pages else browser.new_page()
        page.goto(URL)
        print("Navigate to a meeting chat in the browser, then press Enter here...")
        input()

        # Print all elements that look like chat messages
        messages = page.query_selector_all("[data-tid*='message'], [class*='message'], [role='listitem']")

        for i, el in enumerate(messages[:5]):
            print(f"\n--- Element {i} ---")
            print(f"  tag: {el.evaluate('e => e.tagName')}")
            print(f"  data-tid: {el.get_attribute('data-tid')}")
            print(f"  class (first 100): {(el.get_attribute('class') or '')[:100]}")
            print(f"  text (first 100): {el.inner_text()[:100]}")

        print("\nPress Enter to close...")
        input()
        browser.close()


if __name__ == "__main__":
    main()
```

- [ ] **Step 2: Run the discovery script**

```bash
mkdir -p scripts
.venv/bin/python scripts/discover_dom.py
```

Navigate to a Teams meeting chat, press Enter. Note the `data-tid` values and class names that identify:
1. Individual message containers
2. Sender name elements within messages
3. Profile card container (after clicking a sender name)
4. Email field within the profile card

- [ ] **Step 3: Record findings**

Open `src/teampulse/monitor.py` and add the discovered selectors as constants at the top:

```python
# Discovered via scripts/discover_dom.py — update if Teams web changes
_MSG_SELECTOR = "[data-tid='chat-pane-message']"          # one chat message
_SENDER_SELECTOR = "[data-tid='message-author-name']"     # sender name within message
_PROFILE_EMAIL_SELECTOR = "[data-tid='persona-card-email']"  # email in profile card
```

> **Note:** The selectors above are starting points based on known Teams web patterns. Adjust them based on what `discover_dom.py` shows. Common alternatives:
> - `[class*='authorName']` for sender names
> - `[class*='fui-Persona']` for profile cards

- [ ] **Step 4: Commit**

```bash
git add scripts/discover_dom.py src/teampulse/monitor.py
git commit -m "feat: DOM discovery script and selector constants"
```

- [ ] **Step 2: Verify the module imports cleanly**

```bash
.venv/bin/python -c "from teampulse.monitor import Monitor, parse_trigger; print('OK')"
```

Expected: `OK`

- [ ] **Step 3: Run full test suite**

```bash
.venv/bin/pytest -v
```

Expected: All tests PASS (polling loop has no unit tests — integration tested in Task 9).

- [ ] **Step 4: Commit**

```bash
git add src/teampulse/monitor.py
git commit -m "feat: chat polling loop and window collection"
```

## Task 8: Resolver — Browser Email Extraction

**Files:**
- Modify: `src/teampulse/resolver.py`

- [ ] **Step 1: Implement `_extract_email_from_profile`**

Replace the `_extract_email_from_profile` stub in `src/teampulse/resolver.py` with:

```python
def _extract_email_from_profile(self, display_name: str) -> str | None:
    import time

    # Find a message from this sender and click their name
    sender_elements = self._page.query_selector_all(
        f"{_SENDER_SELECTOR}"
    )
    target = None
    for el in sender_elements:
        if el.inner_text().strip() == display_name:
            target = el
            break

    if target is None:
        print(f"  Sender '{display_name}' nicht im Chat gefunden.")
        return None

    try:
        target.click()
        # Wait for profile card to appear
        self._page.wait_for_selector(_PROFILE_EMAIL_SELECTOR, timeout=5000)
        email_el = self._page.query_selector(_PROFILE_EMAIL_SELECTOR)
        email = email_el.inner_text().strip() if email_el else None

        # Close profile card by pressing Escape
        self._page.keyboard.press("Escape")
        time.sleep(0.5)
        return email
    except Exception as e:
        print(f"  Profilkarte für '{display_name}' nicht ladbar: {e}")
        self._page.keyboard.press("Escape")
        return None
```

Also add the selector constant import at the top of `resolver.py`:

```python
from teampulse.monitor import _PROFILE_EMAIL_SELECTOR, _SENDER_SELECTOR
```

- [ ] **Step 2: Run the cache tests to ensure nothing broke**

```bash
.venv/bin/pytest tests/test_resolver_cache.py -v
```

Expected: All 6 tests PASS.

- [ ] **Step 3: Commit**

```bash
git add src/teampulse/resolver.py
git commit -m "feat: browser-based email extraction from Teams profile cards"
```

## Task 9: Auth — Session Management

**Files:**
- Create: `src/teampulse/auth.py`

- [ ] **Step 1: Write auth.py**

`src/teampulse/auth.py`:

```python
from pathlib import Path

from playwright.sync_api import BrowserContext, Playwright

SESSION_DIR = Path.home() / ".teampulse" / "session"


def create_context(playwright: Playwright, headless: bool = True) -> BrowserContext:
    SESSION_DIR.mkdir(parents=True, exist_ok=True)
    context = playwright.chromium.launch_persistent_context(
        str(SESSION_DIR),
        headless=headless,
        args=["--no-sandbox"],
        locale="de-DE",
    )
    return context


def ensure_logged_in(context: BrowserContext) -> None:
    """
    Open Teams web. If redirected to a login page, make the browser
    visible so the user can authenticate. Waits until login is complete.
    """
    page = context.pages[0] if context.pages else context.new_page()
    page.goto("https://teams.microsoft.com")

    if _is_login_page(page):
        print("Bitte im Browser-Fenster anmelden (SSO/MFA)...")
        # Make browser visible for login
        page.evaluate("document.title = 'TeamPulse Login'")
        page.wait_for_url("**/teams.microsoft.com/**", timeout=120_000)
        print("Anmeldung erfolgreich.")

    page.close()


def _is_login_page(page) -> bool:
    try:
        page.wait_for_url("**/login**", timeout=3000)
        return True
    except Exception:
        return False
```

- [ ] **Step 2: Verify import**

```bash
.venv/bin/python -c "from teampulse.auth import create_context, ensure_logged_in; print('OK')"
```

Expected: `OK`

- [ ] **Step 3: Commit**

```bash
git add src/teampulse/auth.py
git commit -m "feat: Playwright session management with login detection"
```

## Task 10: Main Entry Point

**Files:**
- Create: `main.py`

- [ ] **Step 1: Write main.py**

```python
#!/usr/bin/env python3
"""TeamPulse — Teams meeting chat audit tool.

Usage:
    .venv/bin/python main.py

The script opens a background browser, navigates to Teams.
Post !start "Presenter Name" and !stop in the meeting chat to define a time window.
A Markdown memo is saved to the current directory when the window closes.
"""
from pathlib import Path

from playwright.sync_api import sync_playwright

from teampulse.auth import create_context, ensure_logged_in
from teampulse.memo import generate_memo, save_memo
from teampulse.models import AuditEntry
from teampulse.monitor import Monitor
from teampulse.resolver import Resolver

CACHE_PATH = Path.home() / ".teampulse" / "cache.json"


def main():
    with sync_playwright() as playwright:
        print("Starte Browser...")
        context = create_context(playwright, headless=False)
        ensure_logged_in(context)

        page = context.new_page()
        page.goto("https://teams.microsoft.com")

        monitor = Monitor(page=page, current_user="")
        print("Lese eingeloggten Nutzer...")
        current_user = monitor.get_current_user_display_name()
        monitor._current_user = current_user
        print(f"Eingeloggt als: {current_user}")

        print("\nNavigiere im Browser zur Meeting-Chat-Seite.")
        print("Poste dann '!start \"Name des Vortragenden\"' im Chat.\n")

        window = monitor.run()

        resolver = Resolver(cache_path=CACHE_PATH, page=page)
        print(f"\nLöse {len(window.entries)} E-Mail-Adressen auf...")
        resolved_entries = []
        for entry in window.entries:
            email = resolver.resolve(entry.display_name)
            print(f"  {entry.display_name} → {email}")
            resolved_entries.append(AuditEntry(display_name=entry.display_name, email=email))

        window.entries = resolved_entries

        memo_content = generate_memo(window)
        path = save_memo(memo_content)

        print(f"\nMemo gespeichert: {path}")
        print("\n" + memo_content)

        context.close()


if __name__ == "__main__":
    main()
```

- [ ] **Step 2: Run full test suite one last time**

```bash
.venv/bin/pytest -v
```

Expected: All tests PASS.

- [ ] **Step 3: Smoke test (optional, requires active Teams session)**

```bash
.venv/bin/python main.py
```

Expected: Browser opens, navigates to Teams. After login, monitoring starts.

- [ ] **Step 4: Commit**

```bash
git add main.py
git commit -m "feat: main entry point wiring all components"
```

## Self-Review Notes

- **Spec coverage:** All spec requirements are covered: Playwright + Teams web (✓), persistent session (✓), `!start "Name"` / `!stop` triggers (✓), console Enter fallback — **gap:** console Enter fallback is mentioned in spec but not implemented. It can be added later as a threading enhancement to `monitor.run()` without changing the architecture.
- **Selector constants:** Defined in `monitor.py` and imported by `resolver.py` — consistent across both files.
- **`AuditEntry.email`:** Initialized as `""` in `monitor.py` Task 7 and filled in `main.py` after resolution — intentional two-phase design.
- **`_PROFILE_EMAIL_SELECTOR` and `_SENDER_SELECTOR`:** Exported from `monitor.py` and imported in `resolver.py` — single source of truth for DOM selectors.
