The concept of Sacred Time (Kairos) makes Anthropic's name for new agent more meaningful and clever:
Gemini summarizes info about Anthropic's Kairos:
KAIROS is a leaked, unreleased feature from Anthropic designed as a persistent, always-on background agent for Claude Code (Anthropic’s terminal-based developer tool). Information about it surfaced in late March 2026 when a routine update inadvertently included unminified source code, revealing a departure from the traditional "prompt-and-response" AI model toward proactive, autonomous collaboration.
Core Philosophy: The "Opportune Moment"
The name stems from the Greek concept of Kairos, which refers to the "right or opportune moment" (as opposed to Chronos, sequential time). This reflects the agent's design: instead of constant interruptions, it is built to watch, wait, and act only when it is most appropriate or necessary.
Key Features and Capabilities:
Based on the leaked source code and developer analysis, KAIROS includes several groundbreaking autonomous systems:
Daemon Mode: Operates as a persistent background process that continues working even after the user closes their terminal or goes offline.
Proactive Notifications: Can independently identify tasks (like fixing a bug or summarizing a pull request) and send push notifications or alerts to the user when progress is made.
"autoDream" Memory Consolidation: Perhaps the most unique feature, this is a reflective process that runs during periods of user inactivity. The agent "dreams"—reviewing its logs, removing contradictions, and synthesizing daily experiences into structured, long-term memory.
Risk Classification: Actions are categorized into Low, Medium, and High risk tiers. Low-risk actions are performed autonomously, while high-risk changes (like pushing code to production) require explicit human approval.
Undercover Mode: A specialized mode that allows the agent to contribute to public open-source repositories without identifying itself as an AI, stripping out mentions of "Claude Code" or Anthropic internal codenames.
Workflow Integration: Includes tools like SubscribePR to monitor GitHub activity and Send UserFile to deliver reports and summaries directly to the user.
Comparison to Standard AI
Status
As of April 2026, KAIROS remains an unreleased feature. While the code exists within the Claude Code framework, it is currently gated behind feature flags. It is widely speculated to be part of a future "Mythos" or "Capybara" tier that Anthropic is developing to compete with upcoming autonomous systems from OpenAI and others.
