Use when managing the pynchy service on the server — deploying changes, observing logs, checking service status, restarting the service, setting up GitHub auth, rebuilding the agent container, or running commands on the live Pynchy host. Also use when interacting with the LiteLLM proxy — investigating failed requests, model routing errors, spend tracking, health checks, API gateway diagnostics, or modifying the LiteLLM configuration. Also use when the user mentions the LiteLLM UI, dashboard, proxy errors, or model availability.
Use when creating, scaffolding, or updating a pynchy plugin, including channels, MCP servers, skills, agent cores, workspace specs, and container runtime plugins. Also use when users ask how to register plugins via config.toml, add entry points, or validate plugin hook wiring.
Drive a host desktop through Pynchy's policy-mediated provider plugins when browser automation is inappropriate.
How to use browser tools for web navigation and interaction
Post tweets, like, reply, retweet, and quote on X (Twitter) using browser automation. Use when the user asks you to interact with X/Twitter.
When running multi-line Python code or code with quotes, apostrophes, or f-strings via Bash, always use heredoc syntax instead of python -c to avoid shell quoting issues.

Refresh expired Slack browser session tokens (xoxc/xoxd) used by Slack MCP server.
Need system Chrome/Chromium binary — CHROME_PATH must set in .env (e.g. CHROME_PATH=/usr/bin/google-chrome-stable). Playwright bundled Chromium never used — services fingerprint as bot traffic.
On headless servers, setup_slack_session also need VNC stack for interactive login:
apt install xvfb x11vnc novnc
Plugin check missing deps at startup, log warnings.
Use Playwright persistent browser contexts — after one manual login (human handle CAPTCHA/magic-link), later token extractions run headless using saved session.
Before tokens auto-refresh, human must log in once:
setup_slack_session(workspace_name="acme")
Open visible Chromium window. Human complete Slack login flow (CAPTCHA, magic link, SSO — whatever Slack require). Session saved for future headless use.
On headless server (no X display), tool auto-start virtual display with noVNC web access on port 6080. Before calling setup_slack_session, tell human open http://<server>:6080/vnc.html?autoconnect=true in browser so can interact with login page.
Hardware security keys (YubiKey, FIDO2): noVNC cannot forward WebAuthn challenges — key must physically connect to machine running browser. If Slack login need hardware key, run setup_slack_session on local machine with key attached, then rsync profile to server:
rsync -az data/playwright-profiles/acme/ server:/path/to/pynchy/data/playwright-profiles/acme/
Once session set up, tokens refresh headless:
refresh_slack_tokens(
workspace_name="acme",
xoxc_var="SLACK_XOXC_ACME",
xoxd_var="SLACK_XOXD_ACME",
)
Tool navigate to Slack using saved session, extract fresh tokens, write to .env. pynchy service auto-restart on .env changes.
