Raven

Raven is The Self-Improving Agent Harness, built on EverOS, with opt-in Deep Research for multi-source investigation.

Raven helps agents improve across runs by continuously refining the systems around them: tools, skills, memory, code execution, policies, and working environment. EverOS provides durable user memory, agent memory, and world knowledge across sessions, so successful workflows can evolve into reusable Agent Templates and digital workers.

Update: Raven added Deep Research. Enable it with raven deep-research enable to give the agent access to MiroThinker-backed, multi-source research when a task needs deeper investigation.

Raven is pre-alpha. Interfaces and configuration may change quickly.

Quick Start

Install

Linux, macOS, or WSL2:

curl -fsSL https://raven.evermind.ai/install.sh | bash

Native Windows PowerShell:

irm https://raven.evermind.ai/install.ps1 | iex

Windows PowerShell 5.1 may reject the redirect. Use the direct installer URL instead:

irm https://raw.githubusercontent.com/EverMind-AI/Raven/refs/heads/main/install.ps1 | iex

Onboard and run

raven

That is the whole first run: with nothing configured yet, raven walks you through setup and then opens the TUI in the same session. To reconfigure later, run raven onboard explicitly.

The bilingual onboarding wizard configures six areas without requiring manual edits to ~/.raven/config.json:

  1. LLM provider and model
  2. Sandbox or execution location
  3. Chat channels
  4. EverOS long-term memory
  5. Deep Research
  6. Cold-start import from other AI tools

Provider setup includes an in-step connectivity check. Optional steps can be skipped and configured later. If setup is incomplete, run:

raven doctor

Upgrade

raven upgrade --check
raven upgrade

Upgrades preserve configuration, sessions, and memory. Raven does not update automatically.

Deep Research

Deep Research gives Raven a dedicated path for open-ended questions that require broad web search, source reading, analysis, and multi-source cross-checking. It uses MiroThinker and returns a self-contained answer with inline citations and references.

Configure it during onboarding or later:

raven deep-research enable
raven deep-research get

Once configured, Raven can invoke deep_research when a task needs more than a quick lookup. Before a paid, minute-scale run, interactive surfaces ask whether to use Deep Research or regular search for that query.

Delivery adapts to where Raven is running:

  • CLI and TUI: progress streams inline while Raven searches, reads pages, and runs analysis. The completed report is shown directly without being rewritten by the main model.
  • Gateway channels: the run continues in the background and the completed report is delivered back to the originating conversation.
  • Local archive: every completed result is saved under <workspace>/deep_research/ for later use.

Use regular search for a single fact or URL. Use Deep Research for comparisons, landscape reviews, technical investigations, and questions where source agreement matters.

Tracing

Tracing makes Raven's reasoning path inspectable without sending trace data to a hosted service. Open the local dashboard with:

raven tracing

Each session.turn becomes a trace tree containing the work that happened beneath it:

  • LLM calls, models, token usage, cost, latency, and errors
  • Tool inputs and outputs
  • Subagent runs and parent-child relationships
  • Skill reads and injections
  • Memory recall, storage, extraction, and consolidation
  • Large prompts and results stored as out-of-line artifacts

Tracing is enabled by default and is designed to never interrupt Raven's control flow. Spans are stored locally at ~/.raven/traces/logs/audit-spans.log; set RAVEN_TRACING_DIR to move the state directory or RAVEN_TRACING=0 to disable recording.

The schema follows a small, versioned semantic contract. See the Tracing Standard API for span names, attributes, artifact behavior, and extension rules.

Core Systems

SystemWhat it adds
EverOS memoryDurable user memory, agent memory, and world knowledge across sessions
Context EngineExplicit token budgets and a unified assembly pipeline that preserves the most useful context
ProactivitySentinel observations, scheduled work, nudge policy, and deferred decisions
SkillForgeBuilt-in, workspace, EverOS, and mirrored skills with retrieval, feedback, and evolution
EvolverReproducible evaluation loops for improving agents and reusable procedures
Agent TemplatesShareable starting points for specialized digital workers built on the same harness

Providers and Gateways

Raven supports API-key, OAuth, local, and OpenAI-compatible providers. The onboarding catalog includes OpenRouter, OpenAI, Anthropic, Gemini, MiniMax, DeepSeek, Z.ai, DashScope, Moonshot, VolcEngine, SiliconFlow, Groq, AiHubMix, Azure OpenAI, GitHub Copilot OAuth, OpenAI Codex OAuth, Ollama, and hosted vLLM.

Twelve gateway adapters connect Raven to Telegram, Slack, Discord, WhatsApp, Matrix, Feishu, WeCom, Mochat, QQ, DingTalk, Email, and WeChat.

The Python runtime and React/Ink TUI communicate only through typed TUI-RPC. The Spine carries runtime events, while the Agent Loop coordinates providers, tools, context, memory, skills, subagents, and proactive work.
