Coordinators juggle sign-up forms, shift schedules, reminder calls, last-minute cancellations, and appreciation outreach. An AI agent can handle routine coordination while keeping a human coordinator informed of issues that require judgment. This tutorial builds a volunteer management agent that registers volunteers, matches them to shifts based on skills and availability, sends reminders, and tracks hours for recognition programs. ## Modeling Volunteers and Shifts Start with clean data structures that capture what the agent needs to make scheduling decisions. ```mermaid flowchart LR CALLER(["Donor or Volunteer"]) subgraph TEL["Telephony"] SIP["Twilio SIP and PSTN"] end subgraph BRAIN["Nonprofit AI Agent"] STT["Streaming STT Deepgram or Whisper"] NLU{"Intent and Entity Extraction"} TOOLS["Tool Calls"] TTS["Streaming TTS ElevenLabs or Rime"] end subgraph DATA["Live Data Plane"] CRM[("CRM and Notes")] CAL[("Calendar and Schedule")] KB[("Knowledge Base and Policies")] end subgraph OUT["Outcomes"] O1(["Donation pledge captured"]) O2(["Volunteer slot booked"]) O3(["Program lead handoff"]) end CALLER --> SIP --> STT --> NLU NLU -->|Lookup| TOOLS TOOLS CRM TOOLS CAL TOOLS KB NLU --> TTS --> SIP --> CALLER NLU -->|Resolved| O1 NLU -->|Schedule| O2 NLU -->|Escalate| O3 style CALLER fill:#f1f5f9,stroke:#64748b,color:#0f172a style NLU fill:#4f46e5,stroke:#4338ca,color:#fff style O1 fill:#059669,stroke:#047857,color:#fff style O2 fill:#0ea5e9,stroke:#0369a1,color:#fff style O3 fill:#f59e0b,stroke:#d97706,color:#1f2937 ``` ```python from dataclasses import dataclass, field from datetime import datetime, date, time from typing import Optional from enum import Enum from uuid import uuid4 class ShiftStatus(Enum): OPEN = "open" FILLED = "filled" IN_PROGRESS = "in_progress" COMPLETED = "completed" CANCELLED = "cancelled" @dataclass class Volunteer: volunteer_id: str = field(default_factory=lambda: str(uuid4())) name: str = "" email: str = "" phone: Optional[str] = None skills: list[str] = field(default_factory=list) availability: list[str] = field(default_factory=list) total_hours: float = 0.0 shifts_completed: int = 0 @dataclass class Shift: shift_id: str = field(default_factory=lambda: str(uuid4())) event_name: str = "" role: str = "" shift_date: date = field(default_factory=date.today) start_time: time = field(default_factory=lambda: time(9, 0)) end_time: time = field(default_factory=lambda: time(12, 0)) location: str = "" required_skills: list[str] = field(default_factory=list) spots_total: int = 1 spots_filled: int = 0 assigned_volunteers: list[str] = field(default_factory=list) status: ShiftStatus = ShiftStatus.OPEN ``` ## Building the Registration Tool The agent needs to register new volunteers and capture their skills and availability. ```python from agents import function_tool # In-memory store for demonstration volunteer_db: dict[str, Volunteer] = {} @function_tool async def register_volunteer( name: str, email: str, phone: str, skills: list[str], availability: list[str], ) -> dict: """Register a new volunteer with their skills and availability.""" # Check for duplicate registration for v in volunteer_db.values(): if v.email == email: return { "status": "already_registered", "volunteer_id": v.volunteer_id, "message": f"{name} is already registered.", } volunteer = Volunteer( name=name, email=email, phone=phone, skills=[s.lower() for s in skills], availability=[d.lower() for d in availability], ) volunteer_db[volunteer.volunteer_id] = volunteer return { "status": "registered", "volunteer_id": volunteer.volunteer_id, "message": f"Welcome, {name}! You are now registered.", } ``` ## Shift Matching and Assignment The scheduling tool matches volunteers to shifts based on skill overlap and day-of-week availability. ```python shift_db: dict[str, Shift] = {} @function_tool async def find_matching_shifts( volunteer_id: str, ) -> dict: """Find open shifts that match a volunteer's skills and availability.""" volunteer = volunteer_db.get(volunteer_id) if not volunteer: return {"error": "Volunteer not found"} matches = [] for shift in shift_db.values(): if shift.status != ShiftStatus.OPEN or shift.spots_filled >= shift.spots_total: continue day_name = shift.shift_date.strftime("%A").lower() skill_match = not shift.required_skills or any( s in volunteer.skills for s in shift.required_skills) if day_name in volunteer.availability and skill_match: matches.append({ "shift_id": shift.shift_id, "event": shift.event_name, "date": str(shift.shift_date), "spots_left": shift.spots_total - shift.spots_filled, }) return {"matches": matches, "count": len(matches)} @function_tool async def assign_volunteer_to_shift( volunteer_id: str, shift_id: str, ) -> dict: """Assign a volunteer to a specific shift.""" volunteer = volunteer_db.get(volunteer_id) shift = shift_db.get(shift_id) if not volunteer: return {"error": "Volunteer not found"} if not shift: return {"error": "Shift not found"} if volunteer_id in shift.assigned_volunteers: return {"error": "Already assigned to this shift"} if shift.spots_filled >= shift.spots_total: return {"error": "Shift is full"} shift.assigned_volunteers.append(volunteer_id) shift.spots_filled += 1 if shift.spots_filled >= shift.spots_total: shift.status = ShiftStatus.FILLED return { "status": "assigned", "volunteer": volunteer.name, "shift": shift.event_name, "date": str(shift.shift_date), "role": shift.role, } ``` ## Reminders and Appreciation Automated reminders reduce no-shows, and post-shift appreciation messages improve retention. ```python @function_tool async def send_shift_reminder( volunteer_id: str, shift_id: str, ) -> dict: """Send a reminder to a volunteer about an upcoming shift.""" volunteer = volunteer_db.get(volunteer_id) shift = shift_db.get(shift_id) if not volunteer or not shift: return {"error": "Volunteer or shift not found"} return { "status": "sent", "recipient": volunteer.email, "shift": shift.event_name, "date": str(shift.shift_date), } @function_tool async def log_hours_and_thank( volunteer_id: str, shift_id: str, hours_worked: float, ) -> dict: """Log volunteer hours and send an appreciation message.""" volunteer = volunteer_db.get(volunteer_id) if not volunteer: return {"error": "Volunteer not found"} volunteer.total_hours += hours_worked volunteer.shifts_completed += 1 milestone = "" if volunteer.total_hours >= 100: milestone = " You have reached 100+ hours — Gold level!" elif volunteer.total_hours >= 50: milestone = " You have reached 50+ hours — Silver level!" return { "status": "logged", "total_hours": volunteer.total_hours, "shifts_completed": volunteer.shifts_completed, "milestone": milestone, } ``` ## Assembling the Agent ```python from agents import Agent, Runner volunteer_agent = Agent( name="Volunteer Coordinator Agent", instructions="""You are a volunteer coordinator agent. Your responsibilities: 1. Register new volunteers with their skills and availability 2. Find shifts that match a volunteer's profile 3. Assign volunteers to shifts they are interested in 4. Send reminders 24 hours before shifts 5. Log hours after shifts and send appreciation 6. Track milestones (50 hours = Silver, 100 = Gold) 7. If no shifts match, suggest the volunteer broaden availability 8. Always confirm assignment details before finalizing""", tools=[ register_volunteer, find_matching_shifts, assign_volunteer_to_shift, send_shift_reminder, log_hours_and_thank, ], ) result = Runner.run_sync( volunteer_agent, "Maria Garcia wants to volunteer. Her email is maria@example.com, " "phone 555-0199. She has skills in cooking and event setup, and is " "available on Saturdays and Sundays. Please register her and find " "matching shifts.", ) print(result.final_output) ``` ## FAQ ### How does the agent handle last-minute cancellations? Add a `cancel_assignment` tool that removes the volunteer from the shift, reopens the spot, and triggers a notification to the waitlist. The agent can then proactively reach out to other qualified volunteers to fill the gap, prioritizing those who have expressed interest in similar shifts. ### Can the agent handle background check requirements? Yes. Add a `background_check_status` field to the Volunteer model. The assignment tool checks this field before confirming shifts that require clearance (such as working with children). If the check is pending, the agent informs the volunteer and places them on a conditional waitlist. ### How do you prevent double-booking a volunteer? The `assign_volunteer_to_shift` tool should check the volunteer's existing assignments for time conflicts before confirming. Query all shifts where the volunteer is assigned, compare the date and time ranges, and reject the assignment if there is any overlap. --- #VolunteerManagement #NonprofitAI #Scheduling #AgenticAI #Python #LearnAI #AIEngineering --- Source: https://callsphere.ai/blog/ai-agent-volunteer-management-signup-scheduling-communication
