Aiden

Autonomous AI Engine — local-first, Windows-native, yours to own

74 skills · 60 tools · 19 providers · 9 channels · AGPL-3.0

A semi-autonomous AI agent that runs on your machine. Touches your files, browser, and shell. Remembers what matters. Built solo. Open source. Still rough in spots.

Try it in 60 seconds

npm install -g aiden-runtime
aiden

That's it. Pick a provider (Groq is free + fastest), paste your key, and start chatting.

Want autonomous triggers?

export AIDEN_DAEMON=1          # PowerShell: $env:AIDEN_DAEMON = "1"
aiden trigger add file --path ~/Documents/inbox --label "watch-inbox" --include "*.txt"
aiden                          # boots the REPL + dispatcher

Drop a file in ~/Documents/inbox/anything.txt and Aiden acts on it. The agent turn is visible via aiden runs list.

What's new in v4.6

Aiden now spawns workers and learns from itself.

• Sub-agents. spawn_sub_agent runs a focused child with an isolated context + intersected toolset; subagent_fanout runs N children in parallel (ensemble or partition) with merge strategies (all / vote / pick-best / combine) and provider rotation across configured fallback slots.
• Operator kill-switch. /spawn-pause on|off|status blocks new sub-agent spawning while in-flight children continue. Marker file at ~/.aiden/spawn.paused so the state survives restart and is shared across REPL, daemon, and MCP runtimes. Optional reason field captured in the typed SUBAGENT_SPAWN_PAUSED error envelope.
• Self-improvement loop foundation. TCE classifications + recoveries persist to two new SQLite tables (failure_signatures, recovery_reports); /recovery list|show|clear surfaces recurring failure patterns across sessions.
• REPL parent-run lineage. Each REPL turn writes its own runs row; sub-agent children link back via spawned_from_run_id. aiden runs list hides children by default and shows a (N children, M OK) badge per parent; --include-children flips to flat view.
• PlannerGuard opt-in. The keyword-based per-turn tool narrower is OFF by default in v4.6 (modern models pick well from the full catalog). Enable via /planner-guard on or AIDEN_PLANNER_GUARD=1 for smaller local models.
• v4.6.1 onboarding redesign. Fresh disclaimer screen, loading sequence, rich provider picker with live /models fetch, 3-step connection probe, success screen, and /walkthrough guided tour. Phase 2 also fixed an MCP-mode subagent_fanout regression that had silently broken in the v4.5 refactor.

What's new in v4.5

Aiden now wakes up by itself.

• Persistent daemon mode (opt-in). AIDEN_DAEMON=1 boots a background service with a SQLite-backed trigger bus. File watchers, webhook endpoints, IMAP polling, and cron schedules all feed the same durable queue.
• Autonomous trigger dispatch. When a trigger fires, a real AidenAgent turn runs end-to-end — same tools, same sandbox, same recovery pipeline as your interactive REPL. Surface the chain with aiden runs show <id>.
• Execution sandbox with risk tiers. Filesystem allowlist + Docker session backend + dry-run preflight. Default on; flip live with /sandbox on|off.
• State-aware browser depth. URL + DOM + iframe-tree capture before/after every browser tool call. Stale-ref auto-retry. Surfaces login / 2FA / captcha / consent blockers as structured cards.
• Continuous error recovery (TCE). 16 failure categories classified per tool call. Smart retry with cooldown. Dead-letter for permanent failures. Recovery report enriches the REPL's capability card.
• Live-flip slash commands. /sandbox, /tce, /browser-depth, /daemon status, /suggestions, /update — toggle every subsystem without restart. Choices persist to config.yaml.
• Update notification + /update CLI. Boot prompt when a newer version is on npm. Skip-this-version persistence. Install-method detection (npm-global / npx / standalone).

Core capabilities

Category	What Aiden does
Inference & providers	19 providers: Anthropic, OpenAI, Groq, Gemini, OpenRouter, Together, NVIDIA NIM, DeepSeek, Mistral, Z.ai, Kimi, MiniMax, Hugging Face, Ollama (fully offline), Nous Portal, custom OpenAI-compatible endpoints. OAuth subscription routing for Claude Pro and ChatGPT Plus.
60 built-in tools	Web search & fetch, deep research, YouTube search, Playwright browser automation (10 tools), file ops, process control, shell exec, code execution, system info, screenshot, clipboard, app launch, media keys, MCP bridge, memory ops, session list/search/summary/recall, skill view/list/manage, aiden_self_update.
74 bundled skills	Composable workflows each with a SKILL.md prompt, optional helper scripts, and tool requirements. GitHub PR/issue workflows, NSE / Upstox / Zerodha trading, Censys / Shodan / VirusTotal lookups, Windows Defender / Task Scheduler, Docker management, YouTube content tools, and more.
Self-promoting memory	USER.md + SOUL.md identity, plus MEMORY.md split between durable facts (compression-protected) and recent-session distillations. Each session ends with a structured summary that graduates durable facts into the protected section. Semantic recall over past sessions via recall_session.
Voice	Edge TTS / Windows SAPI text-to-speech, speech-to-text helpers.
Channel adapters	Discord, Slack, Telegram, WhatsApp, Email (IMAP+SMTP), Webhook, Twilio SMS, iMessage (macOS), Signal — any channel triggers the same agent loop.
Computer use	Screenshot capture, screen-state vision loop, browser automation. Mouse/keyboard automation partial.
v4.5 daemon mode (opt-in)	File watcher / webhook / email IMAP / scheduled triggers route through a durable trigger bus consumed by the Phase 5a dispatcher. Triggers fire → real agent runs → tool calls execute → run_events captures the chain. Off by default.
Plugins	Three bundled plugins: Chrome DevTools Protocol bridge, Claude Pro OAuth, ChatGPT Plus OAuth. Permission-state machine (pending-grant / loaded / suspended).
MCP	Model Context Protocol bridge — stdio + HTTP transports, schema discovery, tool dispatch.
Security moat	Tiered approval engine (safe / caution / dangerous), dangerous-command pattern classifier, honesty enforcement (post-loop scan rewrites false claims), memory guard, planner-guard tool narrowing, SSRF-safe URL fetcher, secret/PII pre-write scanner, skill-teacher (auto-create skills from successful flows).

Architecture

Aiden is a local-first agent loop: provider adapters feed a 90-turn ceiling, every tool call passes through verification + failure classification + recovery, and tool results stream back as structured envelopes the model can reason over. v4.5 added a SQLite daemon foundation alongside the REPL — file watchers and webhook endpoints write to a durable trigger bus, a single-worker dispatcher claims events, and each trigger fires a fresh agent turn keyed by a stable session id. Sandboxed execution (filesystem allow/deny + Docker session backend), state-aware browser observation, and continuous error recovery apply to daemon-fired turns identically to REPL turns.

Install + first run

Linux / WSL / macOS (one-line)

npm install -g aiden-runtime
aiden            # interactive setup wizard fires on first run

Windows (one-line)

npm install -g aiden-runtime
aiden

If you hit native-build errors on Windows, install the windows-build-tools prerequisite first.

Try without installing

npx aiden-runtime

After pulling updates

npm install -g aiden-runtime@latest

Or, from inside a running session, the slash command: /update install

(Aiden also prompts you on boot when a newer version is on npm — see /update auto off to silence.)

Uninstall

npm uninstall -g aiden-runtime

To also wipe your local Aiden home (config, sessions, memory, skills):

# Linux / macOS
rm -rf ~/.aiden

# Windows (PowerShell)
Remove-Item -Recurse -Force $env:LOCALAPPDATA\aiden

Setup wizard

The first time you run aiden, you'll see:

• Disclaimer screen — honest about what Aiden can touch (files, browser, shell)
• Loading sequence — system check, skills load, tools register, memory init
• Provider picker — pick from 19 providers, no defaults — explicit choice
• Live model fetch — Aiden hits the provider's /models API for the current catalog
• 3-step probe — key works → model accessible → tool calls supported
• Success screen — three example prompts to get started
• REPL handoff — first-run hint banner: Tip: try /walkthrough

To re-run the wizard later:

aiden setup

To diagnose without re-running:

aiden doctor

Switching models

Inside the REPL: /model

Picks a provider (with ✓ authed badges next to ones you've configured), fetches the live model list, and saves your choice to config.yaml. Persists across sessions.

To set the default at the env level:

export AIDEN_DEFAULT_PROVIDER=groq
export AIDEN_DEFAULT_MODEL=llama-3.3-70b-versatile

Configuration

Aiden reads ~/.aiden/config.yaml (Linux/macOS) or %LOCALAPPDATA%\aiden\config.yaml (Windows). The setup wizard writes a starter config on first boot; subsequent edits are diff-merged.

Common env vars

Variable	Default	Effect
AIDEN_DAEMON	0	Set to 1 to boot the daemon foundation alongside the REPL
AIDEN_DAEMON_PORT	4200	Daemon HTTP listener port
AIDEN_DAEMON_BIND	127.0.0.1	Loopback-only by default; non-loopback requires AIDEN_API_KEY
AIDEN_DAEMON_DAILY_BUDGET	unset	Hard daily token cap across daemon turns; resets midnight UTC
AIDEN_DAEMON_MODEL	unset	Override model for daemon turns (<provider>/<model>)
AIDEN_SANDBOX	1	0 to disable filesystem allowlist + Docker session backend
AIDEN_TCE	1	0 to disable continuous error recovery
AIDEN_BROWSER_DEPTH	1	0 to disable state-aware browser observation
AIDEN_API_KEY	unset	Required for non-loopback daemon bind
AIDEN_NO_UPDATE_CHECK	0	Set to 1 to silence the boot-time update probe
AIDEN_PLANNER_GUARD	0	Set to 1 to enable keyword-based tool narrowing (helps smaller local models)

Most flags are also flippable live via slash commands.

Troubleshooting

Common issues live in docs/v4.5/troubleshooting.md. Quick reference:

• "daemon already running" — stale ~/.aiden/daemon/runtime.lock; remove it
• Webhook 401 despite valid HMAC — check format (github / gitlab / generic)
• IMAP auth failure — Gmail / Outlook require app passwords, not account passwords
• High RSS / slow drain — run the 72-hour soak (tests/v4/daemon/soak/README.md)
• Boot stuck on wizard — non-TTY stdin (CI / piped); set provider env var or use --no-ui
• /help doesn't list a command — that command likely needs an active session field; run from a real REPL
• npm install permission errors on Windows — install into a real folder (not a drive root like S:\)
