| description | Auto-register or RSVP to events on Lu.ma, Eventbrite, Meetup, Hopin, and
custom event sites — given an event URL and an attendee profile, the
skill drives a real cloud browser to fill the registration form, answer
screener questions from a saved profile, and stop before final submit
for human confirmation. Tracks RSVPs to a local pipeline. Useful for
hackathons, meetups, conferences, and product launches.

Event RSVP
Drive a real browser through event registration end-to-end: parse the form, fill from a saved attendee profile, answer screener questions (T-shirt size, dietary needs, role, company), and stop before submit for human confirmation.
Hard rules:
- Never click final RSVP / Register / Confirm without explicit user confirmation.
- Never invent answers (T-shirt size, dietary, GitHub URL, etc.) — if a field doesn't map to the profile, pause and ask.
- One event per task.
- Refuse to register the user for events that charge money without explicit confirmation of the price.
Setup
composio login
composio link browser_tool
composio connections list
Maintain an attendee profile at ~/Desktop/event-rsvp/profile.json:
{
"first_name": "Alex",
"last_name": "Doe",
"email": "alex@example.com",
"phone": "+1-555-0100",
"company": "Acme Inc",
"role": "Senior Backend Engineer",
"linkedin": "https://www.linkedin.com/in/alexdoe",
"github": "https://github.com/alexdoe",
"twitter": "@alexdoe",
"city": "San Francisco",
"country": "USA",
"tshirt": "M",
"dietary": "no restrictions",
"pronouns": "they/them",
max_event_price_usd: 0 means refuse paid events automatically. Set it higher (with explicit user confirmation per session) to allow paid registrations.
Pipeline
Step 1: Inspect the event + form
composio execute BROWSER_TOOL_CREATE_TASK -d '{
"task": "Capture: event title, date and time, venue (or \"online\"), host/organizer, listed price (or \"free\"), and a short description. Then enumerate every visible registration field as a JSON array of { label, type, required, options }. Do NOT fill or click Register yet. Stop after enumeration.",
"startUrl": "{EVENT_URL}"
}'
Poll BROWSER_TOOL_WATCH_TASK. Review:
- Price >
profile.max_event_price_usd → stop and report to user.
- Required field with no profile mapping → stop and ask.
- Date conflicts → flag (the user can sanity-check).
Step 2: Fill the form (no submit)
composio execute BROWSER_TOOL_CREATE_TASK -d '{
"task": "Fill the registration form using the attendee profile JSON below. CRITICAL: do NOT click Register / Confirm / RSVP. After filling every field, stop on the confirmation screen and report: which fields were filled, which were left blank, and any required field whose options did not match the profile. Profile: {PROFILE_JSON}",
"sessionId": "{session_id_from_step_1}"
}'
Step 3: Show the user the live viewer
composio execute BROWSER_TOOL_GET_SESSION -d '{ "sessionId": "{session_id}" }'
Step 4: Submit on explicit confirmation
composio execute BROWSER_TOOL_CREATE_TASK -d '{
"task": "Click the final Register / RSVP / Confirm button. Capture the confirmation page text and any confirmation number, ticket number, or QR code reference. Return as JSON. If a payment screen appears, STOP — do not enter card details.",
"sessionId": "{session_id}"
}'
Step 5: Log to local pipeline
LOG=~/Desktop/event-rsvp/registrations.json
node -e "
const fs = require('fs');
const p = fs.existsSync('$LOG') ? JSON.parse(fs.readFileSync('$LOG','utf8')) : [];
p.push({
event: '{EVENT_TITLE}',
url: '{EVENT_URL}',
date: '{EVENT_DATE}',
venue: '{VENUE}',
status: 'registered',
registered_at: new Date().toISOString(),
confirmation: '{CONFIRMATION}'
});
fs.writeFileSync('$LOG', JSON.stringify(p, null, 2));
"
Optional: emit an .ics file or push to Google Calendar via a separate skill.
Per-platform notes
| Platform | Notes |
|---|
| Lu.ma | Often one-step. May require login via email magic link — pause if so. Some hosts auto-approve, others require approval; report which. |
| Eventbrite | Multi-step (tickets → details → review). Pause on payment if price > 0. |
| Meetup | Requires Meetup account. Pause on login screen. |
| Hopin / Hopin Sessions | Often requires account creation — pause. |
| Custom (Webflow / Typeform / Tally) | Enumerate first (Step 1), expect unusual field semantics. |
Refuse / pause conditions
- Listed price exceeds
profile.max_event_price_usd.
- Account creation required (passwords, magic links).
- A field asks for credit-card details.
- A required field has no profile mapping.
- The event title or description suggests something the user didn't ask for (e.g., a different city's chapter).
- A CAPTCHA appears.
Batch RSVP
For a list of event URLs (e.g., a hackathon week's worth of side events):
jq -r '.events[]' events.json | while read -r URL; do
echo "→ inspecting $URL"
composio execute BROWSER_TOOL_CREATE_TASK -d "$(jq -n --arg u "$URL" '{
task: "Capture event title, date, price, and enumerate registration fields. Stop after enumeration.",
startUrl: $u
}')"
done
Key use cases
- Hackathon week — RSVP to 10 side events in one sitting (with one human review per event).
- Conference circuit — register for every relevant track/workshop at a multi-day conference.
- Local meetup tracking — auto-RSVP to a recurring meetup series; log attendance.
- Product launches — register for every launch event in a category.
- Founder office hours — sign up to office-hours slots that fill fast.
