KAIROS — Always-On Daemon
A persistent background agent that never sleeps
P0Core Pattern
Summary
Referenced 150+ times. Persistent daemon that receives periodic <tick> prompts every 5 minutes, decides independently whether to act, maintains append-only daily logs, and subscribes to GitHub webhooks. Has a 15-second blocking budget — any action exceeding this gets deferred. Uses 'Brief' output mode for minimal disruption.
Architecture Diagram
Technical Details
Three exclusive tools unavailable to standard Claude Code:
• Push notifications (reach you when terminal is closed)
• File delivery (send created outputs without being asked)
• PR subscriptions (autonomous GitHub monitoring)
Teaser rollout planned April 1–7, full launch gated for May 2026 starting with Anthropic employees.
Implementation Pattern
TypeScript (conceptual)
// KAIROS tick handler pattern (conceptual)
interface DaemonTick {
timestamp: number;
dayLog: string[]; // append-only
blockingBudgetMs: 15000;
}
async function onTick(tick: DaemonTick) {
const actions = await decidePendingActions();
for (const action of actions) {
if (estimatedDuration(action) > tick.blockingBudgetMs) {
defer(action); // exceeds budget, queue for later
continue;
}
await execute(action);
tick.dayLog.push(summarize(action));
}
}Architecture Insight
KAIROS is architecturally significant because it proves that AI daemons are viable in production — not as always-running processes, but as periodic tick-based systems with strict resource budgets. This is closer to cron than to a traditional daemon.
Official / Public Basis
Referenced 150+ times in leaked source. Anthropic has not officially documented KAIROS. Teaser UI elements found in v2.1.89+.
Governance Concerns
Always-on daemons must have strict resource budgets, failure limits, and audit trails. The 15-second blocking budget is a good reference pattern. All daemon actions must be append-only logged.
