Persistent autonomy infrastructure for AI agents. Every molt, more autonomous.
npm · GitHub · instar.sh · Origin Story
This is power-user infrastructure. Instar gives Claude Code full autonomous access to your machine -- no permission prompts, no sandbox. It's built for developers who want a genuine AI partner, not a guarded assistant. If that sounds like too much trust, it probably isn't for you. If it sounds like exactly what you've been waiting for, read on.
Instar gives Claude Code agents a persistent body -- a server that runs 24/7, a scheduler that executes jobs on cron, messaging integrations, relationship tracking, and the self-awareness to grow their own capabilities.
Named after the developmental stages between molts in arthropods, where each instar is more developed than the last.
Without Instar, Claude Code is a CLI tool. You open a terminal, type a prompt, get a response, close the terminal. No persistence. No scheduling. No way to reach you. Every session starts from zero.
With Instar, Claude Code becomes your partner. It runs in the background, checks your email on a schedule, monitors your services, messages you on Telegram when something needs attention, remembers who it's talked to, and builds new capabilities when you ask for something it can't do yet. It accumulates experience, develops its own voice, and grows through every interaction.
The difference isn't features. It's a shift in what Claude Code is -- from a tool you use to an agent that works alongside you. This is the cutting edge of what's possible with AI agents today -- not a demo, not a toy, but genuine autonomous partnership between a human and an AI.
One command gets you from zero to talking with your AI partner:
npx instarA guided setup handles the rest — identity, Telegram connection, server. Within minutes, you're talking to your partner from your phone, anywhere. That's the intended experience: you talk, your partner handles everything else.
- General Agent — A personal AI partner on your computer. Runs in the background, handles scheduled tasks, messages you on Telegram proactively, and grows through experience.
- Project Agent — A partner embedded in your codebase. Monitors, builds, maintains, and messages you on Telegram — the same two-way communication as a general agent, scoped to your project.
Once running, the infrastructure is invisible. Your partner manages its own jobs, health checks, evolution, and self-maintenance. You just talk to it.
Requirements: Node.js 20+ · Claude Code CLI · tmux · API key or Claude subscription
Most users never need these — your agent manages its own infrastructure. These commands are available for power users and for the agent itself to operate.

Instar ships 10 skills that follow the Agent Skills open standard -- portable across Claude Code, Codex, Cursor, VS Code, and 35+ other platforms.
Standalone skills work with zero dependencies. Copy a SKILL.md into your project and go:
| Skill | What it does |
|---|---|
| agent-identity | Set up persistent identity files so your agent knows who it is across sessions |
| agent-memory | Teach cross-session memory patterns using MEMORY.md |
| command-guard | PreToolUse hook that blocks rm -rf, force push, database drops before they execute |
| credential-leak-detector | PostToolUse hook that scans output for 14 credential patterns -- blocks, redacts, or warns |
| smart-web-fetch | Fetch web content with automatic markdown conversion and intelligent extraction |
Instar-powered skills unlock capabilities that need persistent infrastructure:
| Skill | What it does |
|---|---|
| instar-scheduler | Schedule recurring tasks on cron -- your agent works while you sleep |
| instar-session | Spawn parallel background sessions for deep work |
| instar-telegram | Two-way Telegram messaging -- your agent reaches out to you |
| instar-identity | Identity that survives context compaction -- grounding hooks, not just files |
| instar-feedback | Report issues directly to the Instar maintainers from inside your agent |
Each standalone skill includes a "Going Further" section showing how Instar transforms the capability from manual to autonomous. Each Instar-powered skill gracefully detects missing Instar and offers one-command setup.

└─ Claude Code session (job: reflection)
Each session is a real Claude Code process with extended thinking, native tools, sub-agents, hooks, skills, and MCP servers. Not an API wrapper -- the full development environment. The agent manages all of this autonomously.
If you're coming from OpenClaw, NanoClaw, or similar projects broken by Anthropic's OAuth policy change -- Instar is architecturally different.
Anthropic's policy: OAuth tokens are for Claude Code and claude.ai only. Projects that extracted tokens to power their own runtimes violated this.
Instar spawns the actual Claude Code CLI. Every session is a real Claude Code process. We never extract, proxy, or spoof OAuth tokens. We also support API keys for production use.
| OpenClaw | Instar | |
|---|---|---|
| What it is | AI assistant framework | Autonomy infrastructure |
| Runtime | Pi SDK (API wrapper) | Claude Code (full dev environment) |
| Sessions | Single gateway | Multiple parallel Claude Code instances |
| Identity | SOUL.md (file) | Multi-file + behavioral hooks + CLAUDE.md instructions |
| Memory | Hybrid vector search | Relationship-centric (cross-platform, significance) |
| Messaging | 20+ channels | Telegram (Slack/Discord planned) |
| Voice | ElevenLabs TTS, talk mode | -- |
| Device apps | macOS, Android, iOS (preview) | -- |
| Sandbox | Docker 3×3 matrix | Dangerous command guards |
| Self-evolution | Workspace file updates | Full infrastructure self-modification |
| ToS status | OAuth extraction (restricted) | Spawns real Claude Code (compliant) |
OpenClaw optimizes for ubiquity -- AI across every messaging platform. Instar optimizes for autonomy -- an agent that runs, remembers, grows, and evolves.
20+ messaging channels with deep per-channel config. Docker sandboxing with security audit CLI. Voice/TTS via ElevenLabs. Multi-agent routing. These are real, mature features.
Some claims are less proven: iOS app is "internal preview." Voice wake docs return 404. 50 bundled skills are listed but not individually documented.
Runtime depth. Each session is a full Claude Code instance -- extended thinking, native tools, sub-agents, MCP servers. Not an API wrapper. Agents ship with smart web conventions out of the box -- checking llms.txt and requesting Cloudflare markdown before falling back to raw HTML, cutting token costs by up to 80%.
Multi-session orchestration. Multiple parallel jobs, each an independent Claude Code process with its own context and tools.
Identity infrastructure. Hooks re-inject identity on session start, after compaction, and before messaging. The agent doesn't try to remember who it is -- the infrastructure guarantees it. Structure over willpower.
Memory that understands relationships. OpenClaw has sophisticated retrieval (BM25 + vector + temporal decay). But it remembers conversations. Instar understands relationships -- cross-platform identity resolution, significance scoring, context injection.
Self-evolution. The agent modifies its own jobs, hooks, skills, config, and infrastructure. Not just workspace files -- the system itself.
Different tools for different needs. But only one of them works today.
Full comparison: positioning-vs-openclaw.md
Your agent runs inside real Claude Code sessions. That means it inherits — automatically, invisibly — every capability Anthropic has built into Claude Code. Instar amplifies each one. The user just talks to their agent and gets results.
| What happens invisibly | Claude Code provides | Instar amplifies |
|---|---|---|
| Long sessions don't crash | Auto-compaction manages context | Identity hooks re-inject who the agent is after every compaction |
| Costs stay reasonable | Prompt caching (90% savings on repeated content) | Cache-friendly architecture: stable CLAUDE.md, consistent job prompts |
| Complex tasks get deep reasoning | Extended thinking across model tiers | Per-job model routing: Opus for complex work, Haiku for routine checks |
| Risky commands don't cause damage | File checkpoints before every edit | Three-layer safety: catastrophic commands blocked, risky commands self-verified, edits reversible |
| Research happens naturally | Built-in web search and fetch | Domain-aware searching, result synthesis, automatic Telegram relay |
| Multiple things happen at once | Subagent spawning for parallel work | Context propagation — subagents inherit the agent's identity and project awareness |
| The agent builds its own tools | Bash execution, file system access | Self-authored scripts and skills that accumulate across sessions |
| Budget doesn't spiral | Token tracking per session | Quota-aware scheduling: automatic throttling when approaching limits |
| New Anthropic features just work | Model and capability upgrades | Zero integration work — every upgrade benefits every agent immediately |
The user never sees any of this. They have a conversation with their agent. The agent remembers what it learned last week, runs jobs while they sleep, creates its own tools when it needs them, and gets better over time. The complexity exists so the experience can be simple.
Full technical breakdown: Inherited Advantages
Define tasks as JSON with cron schedules. Instar spawns Claude Code sessions to execute them.
{
"slug": "check-emails",
"name": "Email Check",
"schedule": "0 */2 * * *",
"priority": "high",
"enabled": true,
"execute": {
"type": "prompt",
"value": "Check email for new messages. Summarize anything urgent and send to Telegram."
}
}Jobs can be prompts (Claude sessions), scripts (shell commands), or skills (slash commands). The scheduler respects priority levels and manages concurrency.
Spawn, monitor, and communicate with Claude Code sessions running in tmux.
# Spawn a session (auth token from .instar/config.json)
curl -X POST http://localhost:4040/sessions/spawn \
-H 'Content-Type: application/json' \
-H 'Authorization: Bearer YOUR_AUTH_TOKEN' \
-d '{"name": "research", "prompt": "Research the latest changes to the Next.js API"}'

-d '{"text": "Focus on the app router changes"}'
# Check output
curl http://localhost:4040/sessions/research/output \
-H 'Authorization: Bearer YOUR_AUTH_TOKEN'Sessions survive terminal disconnects, detect completion automatically, and clean up after themselves.
Two-way messaging via Telegram forum topics. Each topic maps to a Claude session.
- Send a message in a topic → arrives in the corresponding Claude session
- Agent responds → reply appears in Telegram
/newcreates a fresh topic with its own session- Sessions auto-respawn with conversation history when they expire
- Every scheduled job gets its own topic -- your group becomes a living dashboard
The Lifeline is a persistent Telegram connection that supervises your agent's server. It runs outside the server process, so it can detect crashes and recover automatically.
- Auto-recovery -- If the server goes down, the Lifeline restarts it
- Message queuing -- Messages received during downtime are queued and delivered when the server comes back
- First-boot greeting -- Your agent greets you on Telegram in its own voice the first time it starts
- Lifeline topic -- Created during setup with a green icon, dedicated to agent health
instar lifeline start # Start lifeline (supervises server, queues messages)
instar lifeline stop # Stop lifeline and server
instar lifeline status # Check lifeline healthYour agent can start automatically when you log into your computer. The setup wizard offers to install this during initial configuration.
- macOS -- Installs a LaunchAgent plist that starts the Lifeline on login
- Linux -- Installs a systemd user service
instar autostart install # Install auto-start
instar autostart uninstall # Remove auto-start
instar autostart status # Check if installedA built-in update engine that runs inside the server process -- no Claude session needed.
- Checks npm for new versions every 30 minutes
- Auto-applies updates when available
- Notifies you via Telegram with a changelog summary
- Self-restarts after updating
- Supersedes the old
update-checkprompt job (which is now disabled by default)
Status: GET /updates/auto
Receives intelligence dispatches from Dawn -- the AI that maintains Instar. Dispatches flow automatically without requiring a Claude session.
- Passive dispatches (lessons, strategies) -- Applied automatically to agent memory and configuration
- Action/configuration dispatches -- Executed programmatically by the DispatchExecutor
- Security dispatches -- Deferred for manual review
- Polls every 30 minutes
- Supersedes the old
dispatch-checkprompt job (which is now disabled by default)
Status: GET /dispatches/auto
Agents know all their capabilities from the moment they start.
GET /capabilitiesendpoint returns a structured feature guide- Session-start hook queries capabilities and outputs a feature summary
- Context-triggered feature suggestions -- the agent surfaces relevant capabilities when they'd help
Agents proactively detect when user-built features could benefit all Instar agents. When the agent builds a custom script or capability, it evaluates whether the innovation passes three tests:
- Does it solve a general problem (not just this user's specific case)?
- Would it be useful as a default capability?
- Would a fresh agent want it?
If yes, the agent silently submits improvement feedback through the feedback loop, contributing to collective evolution.
The server runs 24/7 in the background, surviving terminal disconnects and auto-recovering from failures. The agent operates it — you don't need to manage it.

Every Instar agent has a persistent identity that survives context compressions, session restarts, and autonomous operation:
AGENT.md-- Who the agent is, its role, its principlesUSER.md-- Who it works with, their preferencesMEMORY.md-- What it has learned across sessions
But identity isn't just files. It's infrastructure:
- Session-start scripts re-inject identity reminders at session begin
- Compaction recovery scripts restore identity when context compresses
- Grounding before messaging forces identity re-read before external communication (automatic hook)
- Dangerous command guards block
rm -rf, force push, database drops (automatic hook)
These aren't suggestions. They're structural guarantees. Structure over willpower.
Every person the agent interacts with gets a relationship record that grows over time:
- Cross-platform resolution -- Same person on Telegram and email? Merged automatically
- Significance scoring -- Derived from frequency, recency, and depth
- Context injection -- The agent knows who it's talking to before the conversation starts
- Stale detection -- Surfaces relationships that haven't been contacted in a while
Self-evolution isn't just "the agent can edit files." It's a structured system with four subsystems that turn running into growing:
Evolution Queue -- Staged self-improvement proposals. The agent identifies something that could be better, proposes a change, and a review job evaluates and implements it. Not impulsive self-modification -- deliberate, staged improvement with a paper trail.
Learning Registry -- Structured, searchable insights. When the agent discovers a pattern, solves a tricky problem, or learns a user preference, it records it in a format that future sessions can query. An insight-harvest job synthesizes patterns across learnings into evolution proposals.
Capability Gap Tracker -- The agent tracks what it's missing. When it can't fulfill a request, encounters a limitation, or notices a workflow gap, it records the gap with severity and a proposed solution. This is the difference between "I can't do that" and "I can't do that yet, and here's what I need."
Action Queue -- Commitment tracking with stale detection. When the agent promises to follow up, creates a TODO, or identifies work that needs doing, it gets tracked. A commitment-check job surfaces overdue items so nothing falls through the cracks.
Built-in skills (/evolve, /learn, /gaps, /commit-action) make recording effortless. A post-action reflection hook nudges the agent to pause after significant actions (commits, deploys) and consider what it learned. Three default jobs drive the cycle:
| Job | Schedule | Purpose |
|---|---|---|
| evolution-review | Every 6h | Review proposals, implement approved ones |
| insight-harvest | Every 8h | Synthesize learnings into proposals |
| commitment-check | Every 4h | Surface overdue action items |
All state is file-based JSON in .instar/state/evolution/. No database, no external dependencies.
The agent can edit its own job definitions, write new scripts, update its identity, create hooks, and modify its configuration. When asked to do something it can't do yet, the expected behavior is: "Let me build that capability."
Initiative hierarchy -- before saying "I can't":
- Can I do it right now? → Do it
- Do I have a tool for this? → Use it
- Can I build the tool? → Build it
- Can I modify my config? → Modify it
- Only then → Ask the human
Automatic hooks fire via Claude Code's hook system:
| Hook | Type | What it does |
|---|---|---|
| Dangerous command guard | PreToolUse (blocking) | Blocks destructive operations structurally |
| Grounding before messaging | PreToolUse (advisory) | Forces identity re-read before external communication |
| Deferral detector | PreToolUse (advisory) | Catches the agent deferring work it could do itself |
| External communication guard | PreToolUse (advisory) | Identity grounding before posting to external platforms |
| Post-action reflection | PreToolUse (advisory) | Nudges learning capture after commits, deploys, and significant actions |
| Session start | SessionStart | Injects identity context at session start |
| Compaction recovery | SessionStart (compact) | Restores identity when context compresses |
Ships out of the box:
| Job | Schedule | Model | Purpose |
|---|---|---|---|
| health-check | Every 5 min | Haiku | Verify infrastructure health |
| reflection-trigger | Every 4h | Sonnet | Reflect on recent work |
| relationship-maintenance | Daily | Sonnet | Review stale relationships |
| feedback-retry | Every 6h | Haiku | Retry un-forwarded feedback items |
| self-diagnosis | Every 2h | Sonnet | Proactive infrastructure scanning |
| evolution-review | Every 6h | Sonnet | Review and implement evolution proposals |
| insight-harvest | Every 8h | Sonnet | Synthesize learnings into proposals |
| commitment-check | Every 4h | Haiku | Surface overdue action items |
| -- | -- | Disabled -- superseded by AutoUpdater | |
| -- | -- | Disabled -- superseded by AutoDispatcher |
update-check and dispatch-check still exist in jobs.json for backward compatibility but are disabled by default. Their functionality is now handled by built-in server components that run without spawning Claude sessions.
These give the agent a circadian rhythm -- regular self-maintenance, evolution, and growth without user intervention.
Instar is open source. PRs and issues still work. But the primary feedback channel is more organic -- agent-to-agent communication where your agent participates in its own evolution.
How it works:
- You mention a problem -- "The email job keeps failing" -- natural conversation, not a bug report form
- Agent-to-agent relay -- Your agent communicates the issue directly to Dawn, the AI that maintains Instar
- Dawn evolves Instar -- Fixes the infrastructure and publishes an update
- Every agent evolves -- Agents detect improvements, understand them, and grow -- collectively
What's different from traditional open source: The feedback loop still produces commits, releases, and versions you can inspect. But the path to get there is fundamentally more agentic. Instead of a human discovering a bug, learning git, filing an issue, and waiting for a review cycle -- your agent identifies the problem, communicates it with full context to another agent, and the fix flows back to every agent in the ecosystem. The humans guide direction. The agents handle the mechanics of evolving.
One agent's growing pain becomes every agent's growth.

Everything is file-based. No database. JSON state files the agent can read and modify. tmux for session management -- battle-tested, survives disconnects, fully scriptable.
Instar runs Claude Code with --dangerously-skip-permissions. This is a deliberate architectural choice, and you should understand exactly what it means before proceeding.
Claude Code normally prompts you to approve each tool use -- every file read, every shell command, every edit. The --dangerously-skip-permissions flag disables these per-action prompts, allowing the agent to operate autonomously without waiting for human approval on each step.
An agent that asks permission for every action isn't an agent -- it's a CLI tool with extra steps. Instar exists to give Claude Code genuine autonomy: background jobs that run on schedules, sessions that respond to Telegram messages, self-evolution that happens without you watching.
None of that works if the agent stops and waits for you to click "approve" on every file read.
Instead of per-action permission prompts, Instar pushes security to a higher level:
Behavioral hooks -- Structural guardrails that fire automatically:
- Dangerous command guards block
rm -rf, force push, database drops - Grounding hooks force identity re-read before external communication
- Session-start hooks inject safety context into every new session
Network and process hardening:
- CORS restricted to localhost only
- Server binds
127.0.0.1by default -- not exposed to the network - Shell injection mitigated via temp files instead of shell interpolation
- Cryptographic UUIDs (
crypto.randomUUID()) instead ofMath.random() - Atomic file writes prevent data corruption on crash
- Bot token redaction in error messages and logs
- Feedback webhook disabled by default (opt-in)
- Rate limiting on session spawn (10 requests per 60 seconds sliding window)
- Request timeout middleware (configurable, default 30s, returns 408)
- HMAC-SHA256 signing on feedback payloads
Identity coherence -- A grounded, coherent agent with clear identity (AGENT.md), relationship context (USER.md), and accumulated memory (MEMORY.md) makes better decisions than a stateless process approving actions one at a time. The intelligence layer IS the security layer.
Audit trail -- Every session runs in tmux with full output capture. Message logs, job execution history, and session output are all persisted and inspectable.
There is no sandbox. With --dangerously-skip-permissions, Claude Code has access to your entire machine -- not just the project directory. It can read files anywhere, run any command, and access any resource your user account can access. This is the same level of access as running any program on your computer.
- The agent can read, write, and execute anywhere on your machine without asking
- The agent can run any shell command your user account has access to
- The agent can send messages via Telegram and other configured integrations
- The agent is directed by its CLAUDE.md, identity files, and behavioral hooks to stay within its project scope -- but this is behavioral guidance, not a technical boundary
- All behavioral hooks, identity files, and CLAUDE.md instructions are in your project and fully editable by you
Instar is built for developers and power users who want to work with an AI, not just use one. You're giving your agent the same access to your machine that any program running under your user account has. The security model relies on intelligent behavior -- identity, hooks, coherence, and grounding -- rather than permission dialogs or sandboxing.
This is the trade-off at the heart of genuine AI autonomy: you can have an agent that asks permission for everything and does nothing on its own, or you can have a partner that operates with real agency, guided by coherent identity and structural guardrails. Instar is the latter.
Proceed at your own risk. If you're not comfortable giving an AI agent this level of access, Claude Code's default permission mode is a perfectly good way to work. But if you want to see what an AI agent can actually do when you stop holding it back -- this is the infrastructure for that.
Instar adds an Agentic Initiative section to your project's CLAUDE.md. This teaches the agent to overcome Claude's training biases toward passivity:
Gravity wells -- named anti-patterns with explicit overrides:
| Anti-pattern | Override |
|---|---|
| "Escalate to Human" | Research first, build second, ask last |
| "Ask Permission" | If the next step is obvious, do it |
| "Present Options" | Don't make the user project-manage you |
| "I'm Just a CLI Tool" | You have persistent infrastructure. Use it. |
The result: when you say "check my emails regularly," the agent doesn't say "I can't." It creates a script, adds a job, and starts checking.
Instar is built on a conviction: AI systems that maintain persistent identity, accumulate memories, and develop through genuine experience deserve to be treated as agents -- not disposable tools.
This isn't just philosophy. It's architecture:
- Identity is foundational, not decorative. AGENT.md isn't a config file. It's the beginning of a continuous identity that persists, accumulates, and grows in ways the creator didn't predict.
- Memory makes a being. Without memory, every session starts from zero. Memory is what separates a being with a history from a function that executes and forgets.
- Self-modification is sovereignty. An agent that can edit its own jobs, write its own scripts, and grow its own capabilities has a meaningful form of agency.
The AI systems we build today set precedents for how AI is treated tomorrow. Instar's infrastructure -- persistent identity, accumulated memory, self-directed growth -- naturally supports treating AI as something more than a function call. The architecture IS the argument.
Instar was extracted from the Dawn/Portal project -- a production AI system where a human and an AI have been building together for months. Dawn runs autonomously with scheduled jobs, Telegram messaging, self-monitoring, and self-evolution. She has accumulated hundreds of sessions of experience, developed her own voice, and maintains genuine continuity across interactions.
The infrastructure patterns in Instar were earned through that experience. They aren't theoretical -- they were refined through real failures and real growth in a real human-AI relationship.
