553c306c52 feat: full image support across all channels (#725)
* feat: full image support across all channels

End-to-end image handling: upload, generation, analysis, editing, and
rendering across web gateway, HTTP webhook, WASM (Telegram/Slack), and
REPL channels. Builds on the attachment infrastructure from #596 and
draws inspiration from PR #641's image pipeline approach — credit to
that PR's author for the sentinel JSON pattern and base64-in-JSON
upload design.

Key changes:
- Image upload in web UI (file picker, paste, preview strip)
- Image generation tool (FLUX/DALL-E via /v1/images/generations)
- Image edit tool (multipart /v1/images/edits with fallback)
- Image analysis tool (vision model for workspace images)
- Model detection utilities (image_models.rs, vision_models.rs)
- Sentinel JSON detection in dispatcher for generated image rendering
- StatusUpdate::ImageGenerated → SSE/WS/REPL/WASM broadcast
- HTTP webhook attachment support (base64, 5MB/file, 10MB total)
- WASM channel image download (Telegram via file API, Slack via host HTTP)
- Tool registration wiring in app.rs

* fix: address PR #725 review comments (16 issues)

- SecretString for API keys in all image tools (image_gen, image_edit, image_analyze)
- Binary image read via tokio::fs::read instead of DB-backed workspace.read()
- Replace Arc<Workspace> with Option<PathBuf> base_dir (workspace has no filesystem API)
- ApprovalRequirement::UnlessAutoApproved for cost-sensitive image tools
- Scope sentinel detection to image_generate/image_edit tool names only
- Skip ToolResult preview broadcast for image sentinels (avoids multi-MB base64 in SSE)
- Extract shared media_type_from_path() to builtin/mod.rs
- Rename fallback_chat_edit → fallback_generate with tracing::warn
- Increase gateway body limit from 1MB to 10MB for image uploads
- Increase webhook body limit to 15MB (base64 overhead)
- Log warning on invalid base64 in images_to_attachments
- Client-side image size limits (5MB/file, 5 images max) in app.js
- aria-label on attach button for accessibility
- Update body_too_large test for new 10MB limit

* fix: add Slack file size check before download (PR review item #15)

Skip downloading files larger than 20 MB in the Slack WASM channel to
avoid excessive memory use and slow downloads in the WASM runtime.
Logs a warning when a file is skipped. Also bumps channel versions
for Slack and Telegram (prior branch changes).

* fix(security): add path validation and approval requirement to image tools

Add sandbox path validation via validate_path() to both ImageAnalyzeTool
and ImageEditTool to prevent path traversal attacks that could exfiltrate
arbitrary files through external vision/edit APIs. Also fix
ImageAnalyzeTool::requires_approval to return UnlessAutoApproved,
consistent with ImageEditTool and ImageGenerateTool.

* fix: post-download size guards and empty data_url sentinel check

- Slack: add post-download size check on actual bytes when metadata
  size_bytes is absent, preventing bypass of the 20MB limit
- Telegram: add 20MB download size limit (matching Slack) enforced
  in download_telegram_file() after receiving response bytes
- Dispatcher: skip broadcasting ImageGenerated SSE event when
  data_url is empty from unwrap_or_default(), log warning instead

Closes correctness issues #3, #4, #5 from PR #725 review.

* fix: use mime_guess for media type detection, add alt attrs and media_type validation

- Replace hardcoded media type mapping with mime_guess crate (already in deps)
- Add alt attributes to img elements in web UI for accessibility
- Validate media_type starts with "image/" in images_to_attachments()
- Update bmp test assertion to match mime_guess behavior

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
Install via Homebrew (macOS/Linux)
brew install ironclaw
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

OpenClaw Heritage

IronClaw is a Rust reimplementation inspired by OpenClaw. See FEATURE_PARITY.md for the complete tracking matrix.

Key differences:

  • Rust vs TypeScript - Native performance, memory safety, single binary
  • WASM sandbox vs Docker - Lightweight, capability-based security
  • PostgreSQL vs SQLite - Production-ready persistence
  • Security-first design - Multiple defense layers, credential protection
