ea57447649 feat: hot-activate WASM channels, channel-first prompts, unified artifact resolution (#297)
* refactor: unify WASM artifact resolution into registry/artifacts.rs

Consolidate duplicated WASM find/build/install logic from 5+ files into
a single src/registry/artifacts.rs module. This fixes two bugs:
- registry/installer.rs now respects CARGO_TARGET_DIR (was hardcoded)
- channels/wasm/bundled.rs now searches all WASM triples (was wasip2 only)

Also includes: extension manager hot-activation for WASM channels,
extension guidance in LLM prompts, channel manager hot-add support,
webhook router channel lookup, and minor cleanups.

* fix: send approval prompts as messages on WASM channels (Telegram, Slack)

WASM channels mapped ApprovalNeeded status to a typing indicator,
so users on Telegram never saw tool approval prompts — the agent
got stuck in AwaitingApproval and all subsequent messages failed
with "Waiting for approval".

- Intercept ApprovalNeeded in WasmChannel::handle_status_update and
  send the prompt as an actual message via call_on_respond, showing
  tool name, description, parameters, and yes/no/always instructions
- Guard against empty LLM responses after clean_response() strips
  reasoning_content think-tags (defense-in-depth for reasoning models)
- Add reasoning_content fallback to NearAiChatProvider::complete()
  for consistency with complete_with_tools()
- Add debug logging when empty responses are suppressed
- Improve error logging for channel respond() failures
- Register WASM channel webhook routes before credential checks so
  platforms don't deactivate webhook URLs with 404s

* fix: address PR #297 review comments

- ChannelManager::add: use async write().await instead of try_write()
- resolve_target_dir: resolve relative CARGO_TARGET_DIR against crate_dir
- install_wasm_files: log warning on capabilities copy failure
- refresh_active_channel: load capabilities file for webhook secret name
- activate_wasm_channel: validate name against path traversal
- Fix cargo fmt formatting in nearai_chat.rs

* fix: wire up channel runtime for hot-activation and address PR review round 2

- Wire up set_channel_runtime() in main.rs so hot-activation actually works
  (with_channel_runtime was never called — hot-activation was dead code)
- Change ExtensionManager channel runtime fields to RwLock<Option<...>>
  interior mutability so set_channel_runtime(&self) works after Arc wrapping
- Fix artifact tests to use resolve_target_dir() instead of hardcoding
  "target/" (breaks when CARGO_TARGET_DIR is set)
- Fix bundled.rs build hint: cargo component build (not cargo build --target)
- Fix wasm_artifact_path doc: binary_name should not include .wasm extension

* fix: use char-aware truncation to prevent UTF-8 panic in approval prompt

&s[..77] panics on multi-byte UTF-8 (CJK, emoji). Use s.chars().take(77)
for safe truncation at character boundaries.

IronClaw

IronClaw

Your secure personal AI assistant, always on your side

PhilosophyFeaturesInstallationConfigurationSecurityArchitecture


Philosophy

IronClaw is built on a simple principle: your AI assistant should work for you, not against you.

In a world where AI systems are increasingly opaque about data handling and aligned with corporate interests, IronClaw takes a different approach:

  • Your data stays yours - All information is stored locally, encrypted, and never leaves your control
  • Transparency by design - Open source, auditable, no hidden telemetry or data harvesting
  • Self-expanding capabilities - Build new tools on the fly without waiting for vendor updates
  • Defense in depth - Multiple security layers protect against prompt injection and data exfiltration

IronClaw is the AI assistant you can actually trust with your personal and professional life.

Features

Security First

  • WASM Sandbox - Untrusted tools run in isolated WebAssembly containers with capability-based permissions
  • Credential Protection - Secrets are never exposed to tools; injected at the host boundary with leak detection
  • Prompt Injection Defense - Pattern detection, content sanitization, and policy enforcement
  • Endpoint Allowlisting - HTTP requests only to explicitly approved hosts and paths

Always Available

  • Multi-channel - REPL, HTTP webhooks, WASM channels (Telegram, Slack), and web gateway
  • Docker Sandbox - Isolated container execution with per-job tokens and orchestrator/worker pattern
  • Web Gateway - Browser UI with real-time SSE/WebSocket streaming
  • Routines - Cron schedules, event triggers, webhook handlers for background automation
  • Heartbeat System - Proactive background execution for monitoring and maintenance tasks
  • Parallel Jobs - Handle multiple requests concurrently with isolated contexts
  • Self-repair - Automatic detection and recovery of stuck operations

Self-Expanding

  • Dynamic Tool Building - Describe what you need, and IronClaw builds it as a WASM tool
  • MCP Protocol - Connect to Model Context Protocol servers for additional capabilities
  • Plugin Architecture - Drop in new WASM tools and channels without restarting

Persistent Memory

  • Hybrid Search - Full-text + vector search using Reciprocal Rank Fusion
  • Workspace Filesystem - Flexible path-based storage for notes, logs, and context
  • Identity Files - Maintain consistent personality and preferences across sessions

Installation

Prerequisites

  • Rust 1.85+
  • PostgreSQL 15+ with pgvector extension
  • NEAR AI account (authentication handled via setup wizard)

Download or Build

Visit Releases page to see the latest updates.

Install via Windows Installer (Windows)

Download the Windows Installer and run it.

Install via powershell script (Windows)
irm https://github.com/nearai/ironclaw/releases/latest/download/ironclaw-installer.ps1 | iex
Install via shell script (macOS, Linux, Windows/WSL)
curl --proto '=https' --tlsv1.2 -LsSf https://github.com/nearai/ironclaw/releases/latest/download/ironclaw-installer.sh | sh
Compile the source code (Cargo on Windows, Linux, macOS)

Install it with cargo, just make sure you have Rust installed on your computer.

# Clone the repository
git clone https://github.com/nearai/ironclaw.git
cd ironclaw

# Build
cargo build --release

# Run tests
cargo test

For full release (after modifying channel sources), run ./scripts/build-all.sh to rebuild channels first.

Database Setup

# Create database
createdb ironclaw

# Enable pgvector
psql ironclaw -c "CREATE EXTENSION IF NOT EXISTS vector;"

Configuration

Run the setup wizard to configure IronClaw:

ironclaw onboard

The wizard handles database connection, NEAR AI authentication (via browser OAuth), and secrets encryption (using your system keychain). Settings are persisted in the connected database; bootstrap variables (e.g. DATABASE_URL, LLM_BACKEND) are written to ~/.ironclaw/.env so they are available before the database connects.

Alternative LLM Providers

IronClaw defaults to NEAR AI but works with any OpenAI-compatible endpoint. Popular options include OpenRouter (300+ models), Together AI, Fireworks AI, Ollama (local), and self-hosted servers like vLLM or LiteLLM.

Select "OpenAI-compatible" in the wizard, or set environment variables directly:

LLM_BACKEND=openai_compatible
LLM_BASE_URL=https://openrouter.ai/api/v1
LLM_API_KEY=sk-or-...
LLM_MODEL=anthropic/claude-sonnet-4

See docs/LLM_PROVIDERS.md for a full provider guide.

Security

IronClaw implements defense in depth to protect your data and prevent misuse.

WASM Sandbox

All untrusted tools run in isolated WebAssembly containers:

  • Capability-based permissions - Explicit opt-in for HTTP, secrets, tool invocation
  • Endpoint allowlisting - HTTP requests only to approved hosts/paths
  • Credential injection - Secrets injected at host boundary, never exposed to WASM code
  • Leak detection - Scans requests and responses for secret exfiltration attempts
  • Rate limiting - Per-tool request limits to prevent abuse
  • Resource limits - Memory, CPU, and execution time constraints
WASM ──► Allowlist ──► Leak Scan ──► Credential ──► Execute ──► Leak Scan ──► WASM
         Validator     (request)     Injector       Request     (response)

Prompt Injection Defense

External content passes through multiple security layers:

  • Pattern-based detection of injection attempts
  • Content sanitization and escaping
  • Policy rules with severity levels (Block/Warn/Review/Sanitize)
  • Tool output wrapping for safe LLM context injection

Data Protection

  • All data stored locally in your PostgreSQL database
  • Secrets encrypted with AES-256-GCM
  • No telemetry, analytics, or data sharing
  • Full audit log of all tool executions
