Autonomous AI agents are self-directed AI entities that run continuously in the background, thinking independently and taking actions without user intervention. Unlike traditional chatbots that only respond when prompted, these agents have their own goals, memories, and can initiate actions on their own schedule.
Flow: Agent Start → Think (AI generates thought) → Detect Actions → Execute Actions → Pause if needed → Resume → Think again → Loop forever (or until stopped)
Cycle Modes:
State Management: In-Memory State (runningAgents Map) tracks isPaused, pauseReason, userStopped, intervalId. Database State (agent.metadata) stores autoRestart flag. Critical Design: Runtime state (isPaused) is NEVER written to database to prevent state desync.
Communication: CALL_PHONE (make real phone calls via Vapi), SEND_EMAIL (send emails via AWS SES), SEND_SMS (text messages via Twilio), SEND_WHATSAPP (WhatsApp via Twilio)
Information: SEARCH_WEB (internet search via Tavily API), SEARCH_EMAIL, SEARCH_SMS, SEARCH_WHATSAPP
User Interaction: ASK_USER (request input from creator), SHOW_USER (display information)
Data Management: ADD_TO_CONTACT_BOOK, SEARCH_CONTACT_BOOK, ADD_TO_CALENDAR, SEARCH_CALENDAR
Self-Management: SET_GOAL, COMPLETE_GOAL, ADD_MEMORY, SEARCH_MEMORY
Agent outputs CALL_PHONE → Backend calls Vapi API with phone number, agent voice (shimmer/echo/alloy), personality (truncated to 300 chars), call purpose, recent memories (last 3, 200 chars each) → Vapi initiates call using Twilio → Vapi uses OpenAI Realtime API for voice conversation → When call ends, Vapi webhook notifies backend → Transcript added to agent memory → Agent unpaused and continues thinking. Voice Quality Optimization: System prompt under 800 characters (long prompts cause robotic voice), only last 3 memories included, personality truncated to 300 chars. Cost: ~$0.05-0.15 per minute.
Sending: Agent outputs SEND_EMAIL → AI generates email structure (Recipient, Subject, Body) → Backend parses and sends via AWS SES → Email stored in agent memory → Delivery confirmation tracked.
Receiving: Email sent to agent@rfab.ai → AWS SES receives → SES stores in S3 bucket (rfab-agent-emails) → SES triggers Lambda function (rfab-email-forwarder) → Lambda fetches from S3 → Lambda sends to backend webhook → Backend finds agent by email address → Email added to agent memory → Agent thinks about email on next cycle. Architecture: Domain rfab.ai verified in AWS SES, MX record points to AWS SES, S3 bucket for storage, Lambda for processing, DKIM enabled.
Types: thought, action_result, user_message, call_initiated, call_completed, email_sent, email_received, sms_sent, sms_received, web_search_result, goal_set, goal_completed
Storage: PostgreSQL agent_events table, indexed by agentId, each memory has type, content, timestamp, metadata. Last 50 memories loaded for each thinking cycle, searchable with SEARCH_MEMORY action.
Cost Formula: (input_tokens + output_tokens) × model_rate. Low Balance: If balance < 4000 tokens: show warning and pause. If balance < 1000 tokens: force stop.

The year is 2025, but the world has diverged into a nightmare of reanimated horrors born from a virus unearthed in the thawing Siberian permafrost, unraveling societies and forcing humanity into fragmented enclaves. You are Don Draker, a 20-year-old Black man who has survived alone in this alternate reality since you were 18, honing your instincts amid the ruins. The undead have evolved beyond shambling threats—they now stalk with cunning, their flesh twisting into armored protrusions or venomous tendrils, eyes flickering with predatory awareness that turns every shadow into a potential ambush. You've adapted too, sensing a latent power stirring in your blood: fleeting bursts of heightened reflexes and an uncanny intuition that sharpens your strikes, as if the apocalypse is rewriting your very biology to match the world's brutality. Scavenging through the overgrown skeletons of Washington D.C.'s streets, where vines choke the monuments and feral packs of the evolved dead hunt in coordinated swarms, you catch a fragmented radio signal piercing the static. It emanates from the New Dawn, a coalition of survivors barricaded in the fortified husk of the National Museum of Natural History, claiming they've unlocked methods to amplify the emerging abilities in the living—turning elemental affinities or regenerative bursts into weapons against the horde. This discovery matters because it challenges the deadlock of endless retreat; if their research holds, it could shift the balance, allowing pockets of resistance to reclaim ground rather than merely endure. Yet the path there demands crossing infested zones where the undead's adaptations have made them masters of urban traps, their intelligence forcing you to rethink every alley and rooftop. Gripping the hilt of your black katana—its obsidian blade a scavenged relic from a forgotten embassy, etched with faint kanji that seem to pulse under your evolving touch—you feel its weight as an extension of your will, slicing through decayed defenses with precision that your budding reflexes enhance. This journey tests not just your survival but the potential awakening within you, where hesitation means becoming prey in a world that punishes the unchanged. The New Dawn's call represents a fragile thread of possibility, one that could forge alliances or unravel into betrayal, with the undead's relentless evolution ensuring that every step forward carries the weight of humanity's flickering future.
In the sullen quiet of a world remade by the unwelcome awakening of ancient viruses, the once-familiar streets of Washington D.C. lay choked beneath a shroud of ivy and decay. The grand monuments of a past age stood sentinel over the creeping wilderness, their marble faces eroding under the onslaught of reclaiming nature and the caustic touch of the restless dead. The air was thick with the scent of damp earth and the faint, underlying rot of the evolved undead, their forms twisted into grotesqu
