Teams Headless

Teams Headless

Background Microsoft Teams Web V2 chat and transcript extraction using Playwright and Google Chrome. Runs entirely headlessly without UI interference.

Prerequisites

• Google Chrome installed (see path configuration below)
• uv package manager: pip install uv or brew install uv
• One-time auth setup completed (Step 0)

Chrome path configuration

The scripts read CHROME_PATH from the environment, falling back to platform defaults:

# Linux (common paths)
export CHROME_PATH="/usr/bin/google-chrome"
export CHROME_PATH="/usr/bin/chromium-browser"

# macOS
export CHROME_PATH="/Applications/Google Chrome.app/Contents/MacOS/Google Chrome"

User data and downloads are stored under XDG-compliant directories:

• Browser session: $XDG_STATE_HOME/agent-skills/teams-headless/user_data/ (default: ~/.local/state/) — not safe to delete (breaks auth)
• Downloaded images: $XDG_CACHE_HOME/agent-skills/teams-headless/downloads/ (default: ~/.cache/) — safe to delete

Step 0: Setup Auth (one-time)

Log in to establish a persistent browser session:

cd skills/teams-headless/scripts && uv run src/setup_auth.py

A Chrome window opens to https://teams.microsoft.com/v2/. Sign in manually, then press Enter in the terminal. The session is saved and reused for all future headless runs.

Step 1: Extract

Recent messages from a chat

cd skills/teams-headless/scripts

# Search for a chat by person or chat name, return recent messages
uv run src/teams_client.py "Suhasini"

# Control how many messages come back (default: 5)
uv run src/teams_client.py "Suhasini" --limit 20

# Omit the name to read the currently open chat
uv run src/teams_client.py

Meeting recap and transcript

uv run src/teams_client.py "Call to Discuss AMI Creation" --recap

Opens the chat, clicks View recap, switches to the Transcript tab, and returns the transcript segments. If no transcript is found, falls back to the recap pane's text with author "Recap Fallback".

Step 2: Summarise

Output is a JSON array printed to stdout:

[
  {
    "author": "Alice Smith",
    "body": "Message text...",
    "timestamp": null,
    "images": [
      { "alt": "diagram", "src": "https://...", "local_path": null }
    ]
  }
]

Parse the JSON and summarise or analyse the content for the user.

Capabilities

Notes

• Targets Teams Web V2 (teams.microsoft.com/v2/) — selectors are tied to that UI and will need updating if Microsoft changes it.
• Uses CSS selectors and DOM interaction only — no mouse movement or screen automation.
• Session is persistent — re-run setup_auth.py only if the session expires.
• Chat selection and recap loading use fixed waits, so a run takes ~10-30s.
• Behaviour is specified in features/chat_extraction.feature.
