# Decision Points for Embedding AI Agents in Enterprise Systems # Pull vs Push — Agent Activation Models 🎯 The Hook Is your agent designed to only act when a user explicitly calls it? There are actually two fundamentally different activation models: Pull (triggered by explicit user requests) and Push (triggered by system events). The choice between them reshapes user experience, load characteristics, and authorization models. In most production environments, the Pull-to-Push ratio settles somewhere between 7:3 and 5:5 🔑 📋 Overview Pull-based agents respond to explicit user intent — a question to a Slack Bot, a request from a Salesforce opportunity screen. Push-based agents activate automatically from system events (webhooks, CDC, scheduled triggers) to perform anomaly detection and preventive actions. Think of a Jira SLA breach triggering automatic escalation, or a nightly batch detecting attendance anomalies in Workday and presenting corrective recommendations the next morning. In enterprise environments, hybrid configurations combining both models are the norm 📊 🔍 Decision Points Three axes drive this decision: First, can the trigger be defined as a clear system event (webhook, CDC, cron)? If yes, consider Push. Second, is the user's intent and context (current screen, recent actions) essential for execution? If yes, Pull should be your primary model. Third, is there value in "acting before the user notices"? If preemptive action prevents losses — SLA violation prevention, early incident detection — Push is the way to go. When both apply, a hybrid where Push notifies and Pull enables deeper exploration is usually the optimal architecture. If you adopt Push, always design for event volume estimation and throttling ⚡ 💡 Key Details Understanding hybrid patterns is essential for enterprise deployments: Push to alert, Pull to explore — Send summary notifications via event-driven Push. When users want details, they shift to a Pull conversation. A Zendesk customer satisfaction score drops sharply, the agent pushes an alert, and the agent handles the follow-up question "analyze the root cause." Background Push behind Pull — While handling a user's Pull query, the agent monitors related events in the background (unresolved tickets for the same customer) and proactively surfaces additional information. Authorization design deserves special attention with Push. Pull-based agents inherit permissions from the requesting user's session, keeping the authorization model simple. Push-based agents operate outside user sessions, so you must explicitly define which credentials they use for API calls — otherwise you end up with over-privileged service accounts 🔄 ⚖️ Trade-offs Push overload causes notification fatigue. Without properly calibrated event thresholds, a flood of alerts buries the Slack channel in unread notifications. Users start ignoring everything, and genuinely critical alerts get lost in the noise 😩 On the other hand, running Pull-only means missing prevention opportunities. If event sources exist that could detect anomalies but you rely solely on Pull, by the time a user notices, the SLA violation is already a fact. For "too late once noticed" problems, Push is indispensable. Another pitfall is event storms. Mass CDC events right after a deployment or system migration can overwhelm Push agents, causing cascading timeouts. Throttling design must be in place before go-live ⚠️ 🛠️ Use Cases Incident response agent (ServiceNow integration): Push detects P1 incident escalation instantly, auto-sends notification and initial analysis to on-call staff. The responder then uses Pull: "Analyze the blast radius in detail." The agent cross-references logs across related systems and reports findings. A textbook hybrid where Push accelerates first response and Pull enables deep investigation 🏢 Attendance management agent (Workday integration): Nightly Push batch detects attendance anomalies (overtime excess, missed clock-ins) and presents corrective recommendations to managers the next morning. Managers use Pull to ask "What was this department's trend last month?" and receive detailed analytical reports 📚 Sales support agent (Salesforce integration): Push monitors opportunity stage changes and auto-reminds sales reps about deals stagnating too long. Reps use Pull to request "Summarize this customer's past support history," and the agent generates a comprehensive report including Zendesk interaction history 🔧 Practical tip: When introducing Push, start with notification threshold design. Do not notify on every event — build a mechanism that filters for business-impactful events only. Also, apply the principle of least privilege rigorously to Push agent service accounts 💪 #AIAgents# #EnterpriseArchitecture#
