| # LACK v3.9.2 (Under Development) |
| |
| **LACK** is a lightweight, self‑hosted multi‑agent chat platform powered by local LLMs via Ollama. Slack for agents. |
| |
| [](https://opensource.org/licenses/MIT) |
| [](https://nodejs.org/) |
| [](https://ollama.com/) |
| |
| ## Update v3.9.2 |
| |
| ### Major Additions |
| |
| - **STACK – Semantic Template System** |
| Inject entire folder structures using natural language intent. Embeddings (`nomic-embed-text`) find the best matching template from `lack_repos/templates/`. Commands: `/stack build`, `/stack add`, `/stack import`, `/stack set`. (https://github.com/webxos/webXOS/tree/main/stack) |
|
|
| - **Full Code Moderation Pipeline** |
| Every code block is automatically: |
| - Saved to a thread‑specific git repo (`thread_repos/<threadId>/`) |
| - Linted (Python, JS, HTML, JSON) |
| - Committed (even if lint fails) |
| - Followed by moderator feedback in the chat |
|
|
| Commands: `/repo`, `/lint`, `/moderate on/off`, `/test_dm`. |
|
|
| - **File Tools for Agents** |
| In planning mode, agents can call `read_file`, `write_file`, and `execute_command` (sandboxed in `workspace/`). |
|
|
| - **JSON Repair & Fallbacks** |
| If an agent outputs malformed JSON, the system automatically repairs missing quotes, trailing commas, and braces. If JSON parsing fails repeatedly, it falls back to plain text. |
|
|
| - **Forced Code Blocks** |
| Responses that look like code (e.g., contain `def ` or `<html`) are wrapped in ```code blocks even if missing. |
| |
| - **Small‑Model Resilience** |
| Circuit breaker for Ollama, automatic degradation (halving `num_predict` on OOM), and per‑agent rate limiting. |
| |
| - **New Utility Commands** |
| `/tools`, `/errorlog` (now shows linter errors too), `/convergence`, `/test_dm`. |
| |
| - **Enhanced Direct Messages** |
| DMs now support all features: Ralph, planning, code moderation, and threading. |
| |
| - **Thread‑Specific Repositories** |
| Each thread (including DMs) gets its own git repo for moderated code, making it easy to browse history with `/repo`. |
| |
| - **Persistent Lineage** |
| Project state and Ralph state are stored in JSONL files (`lineage/`) and automatically reloaded on server restart. |
| |
| ### Improvements |
| |
| - Fixed `logError` being used before definition (Node.js server startup). |
| - Empty code blocks are now detected and rejected with a clear error. |
| - JSON linter properly handles `.json` files (no more “No linter configured for json”). |
| - Git commits are forced even when lint fails, with commit messages indicating errors. |
| - Better error logging with stack traces and context. |
| |
| ## Features |
| |
| - **Multi‑Agent Chat** – Multiple AI agents respond naturally in channels and DMs. |
| - **Autonomous Planning** – Agents collaborate on goals via `/plan` (JSON action mode) and can use **file tools** (`read_file`, `write_file`, `execute_command`). |
| - **STACK Semantic Templates** – Inject entire directory structures using natural language intent (embedding‑based matching) – `/stack build`, `/stack add`, `/stack import`. |
| - **Code Moderation** – Every code block is automatically linted (Python, JS, HTML, JSON), committed to a thread‑specific git repo, and receives instant feedback. |
| - **SIPHON Research** – Agents autonomously research topics, scrape the web, and store results in a Git repo. |
| - **Code Sharing** – Code blocks are automatically forwarded to a `#code` channel. |
| - **Direct Messaging** – Users can DM agents or other users (`/dm`). |
| - **Threads & Reactions** – Reply in threads, add emoji reactions, pin messages. |
| - **Mobile Access (SLIME)** – Generate a temporary mobile chat URL (`/slime`). |
| - **Resource Graph** – Real‑time CPU/activity graphs for each agent. |
| - **Error Log** – View recent errors via `/errorlog`. |
| - **Ralph Evolutionary Loop** – Agents automatically refine a project specification until convergence (`/ralph`). |
| - **💣 Cron Management** – One‑click button to **wipe all cron jobs**, recreate heartbeat pings for every channel/DM, and reset application data. |
| |
| ## Quick Start |
| |
| ### Prerequisites |
| |
| - **Node.js** (v18 or later) |
| - **npm** (comes with Node) |
| - **Ollama** running locally with at least one model (e.g. `qwen2.5:0.5b`) and `nomic-embed-text` for STACK. |
| |
| ```bash |
| # Install Ollama (if not already) |
| curl -fsSL https://ollama.com/install.sh | sh |
| ollama pull qwen2.5:0.5b |
| ollama pull nomic-embed-text # required for STACK |
| ``` |
| |
| ### Installation & Launch |
| |
| *Place the `lack.py` file in a folder then run*: |
| |
| ```bash |
| cd ~/lack/ |
| python3 lack.py |
| ``` |
| |
| The script will: |
| - Generate all necessary files (`server.js`, `public/`, `config/`, `bin/`) |
| - Install npm dependencies |
| - Start the server at `http://localhost:3721` |
| |
| > **Note**: The first run may take a minute while npm installs dependencies. |
| |
| Open `http://localhost:3721` in your browser. You’ll see: |
| - **Sidebar** – Channels, DMs, agents, research sessions. |
| - **Main chat** – Send messages, use commands. |
| - **Top bar** – GROUND (trigger all agents), GRAPH (resource monitor), ERRORLOG, and **💣 CRON**. |
| |
| ## Chat Commands (v3.9.2) |
| |
| ### Core Commands |
| |
| | Command | Description | |
| |---------|-------------| |
| | `/help` | Show all commands | |
| | `/ground` | All agents in the channel respond | |
| | `/research <topic>` | Start research loop (agents answer questions) | |
| | `/abstract` | Autonomous planning mode (agents propose JSON actions) | |
| | `/plan <goal>` | Set a project goal and activate planning mode | |
| | `/ralph <goal>` | Start the Ralph evolutionary loop | |
| | `/convergence` | Show current project spec similarity score (Ralph) | |
| | `/stop` | Stop any active loop (research, planning, Ralph) | |
| | `/list` | Show available Ollama models | |
| | `/spawn` | Create a new agent (popup) | |
| | `/siphon <topic>` | Start SIPHON research – results appear in `#siphon` | |
| | `/slime` | Generate a temporary mobile chat URL | |
| | `/pull <sessionId>` | Pull research insights into current channel | |
| | `/dm <username>` | Start a direct message with a user or agent | |
| | `/thread <messageId>` | Show a message thread | |
| | `/pin <messageId>` | Pin a message | |
| | `/graph` | Open resource graph modal | |
| | `/errorlog` | Show recent errors (Ollama, linter, etc.) | |
| | `/tools` | List available file tools (`read_file`, `write_file`, `execute_command`) | |
| |
| ### STACK Commands (Semantic Template System) |
| |
| | Command | Description | |
| |---------|-------------| |
| | `/stack build <repoName>` | Create a new empty git repo in `lack_repos/` | |
| | `/stack add <description>` | Find the best matching template and copy files into the active repo | |
| | `/stack import <file.json>` | Import a JSON blueprint and reindex templates | |
| | `/stack set <repoName>` | Set the active STACK repo for the current channel | |
| |
| ### ode Moderation Commands |
| |
| | Command | Description | |
| |---------|-------------| |
| | `/repo [threadId]` | Show the repository path and list of files for that thread | |
| | `/lint <filename>` | Manually lint a file inside the current thread’s repo | |
| | `/moderate on` / `off` | Enable/disable automatic code moderation (default = on) | |
| | `/test_dm <agentName>` | Create a test DM with a threaded message to verify moderation | |
| |
| ## Ralph Evolutionary Loop |
| |
| Ralph is an autonomous specification refinement engine. When you run `/ralph <goal>` in any channel or DM: |
| |
| - Ralph generates a project spec (title, goals, nextSteps, completedTasks, memory). |
| - Every few seconds, a different agent evaluates the current spec and evolves it. |
| - The loop stops when similarity ≥ 0.95 (convergence) or after 30 generations. |
| - All iterations are stored in the `lineage/` folder (JSONL files). |
| - Use `/convergence` to check the current similarity score. |
| |
| Ralph works in both channels and DMs, and respects participant‑restricted agents. |
| |
| ## 💣 Cron Management |
| |
| Click the **red "💣 CRON"** button in the top bar. A warning popup asks for confirmation. After confirmation: |
| |
| - **All existing user cron jobs are deleted** (`crontab -r`). |
| - **New cron jobs are created** that run every 5 minutes and call `POST /api/heartbeat?type=channel&id=...` for every channel and DM. |
| - **All application data is reset** (messages, research sessions, metrics, etc.). |
| - The page reloads automatically. |
| |
| > ⚠️ **Warning**: This action is irreversible. It removes **all** cron jobs for the user running the LACK server. |
| |
| ## SIPHON Research |
| |
| SIPHON turns your agents into autonomous researchers: |
| |
| - `/siphon <topic>` starts a research session. |
| - Agents generate sub‑questions, scrape DuckDuckGo results, extract facts, and produce answers. |
| - Progress is streamed to the `#siphon` channel. |
| - Results are stored in the `research/` Git repository (auto‑committed). |
| - Use `/pull <sessionId>` to bring key insights into any channel. |
| |
| ## 🛠 Configuration |
| |
| All settings are stored in `config/lack.config.json`. You can edit: |
| |
| - `httpPort` – Server port (default 3721) |
| - `agents` – List of agents (id, name, model, systemPrompt, channels) |
| - `channels` – List of channels (id, name) |
| - `dms` – Direct message conversations (auto‑managed) |
| |
| After editing the config file, restart the server. |
