Multi-platform agentic AI harness. Runs on Telegram, WhatsApp, Discord, Microsoft Teams, the Terminal, and a cross-platform Desktop/Mobile companion app (Flutter), with a pluggable backend (Claude Agent SDK, Kilo, OpenCode, Codex, Antigravity, or OpenAI Agents) and full tool access through MCP.
Features
| Multi-frontend | Telegram (grammY + GramJS userbot), WhatsApp (Baileys multi-device), Discord (discord.js), Microsoft Teams (Bot Framework), Terminal with live tool visibility, and a Desktop/Mobile app (Flutter) over a local/remote bridge — one or several at once, see Frontends |
| Pluggable backend | Claude Agent SDK, Kilo, OpenCode, Codex, Antigravity, OpenAI Agents — selectable per-process via backend config. Streaming, model fallback, context-overflow recovery. |
| MCP tools | Messaging, media, history, search, web fetch, cron jobs, triggers, goals, stickers, file system, admin controls |
| Plugins | Hot-reloadable plugin system with talon plugin install/enable/disable (npm, git, or local sources). Built-in: GitHub, MemPalace, Playwright, Brave Search |
| Background agents | Heartbeat (hourly by default — advances goals, proactively messages when something matters) and Dream (memory consolidation + diary) |
| Goals | Persistent multi-day objectives the agent commits to in chat; every heartbeat run re-reads them, makes progress, and records what it did |
| Skills | SKILL.md workflow bundles the agent authors and reuses, with talon skill install/enable/disable (local folders, git, or owner/repo — the Anthropic skills ecosystem installs directly) |
| Triggers | Self-authored watcher scripts (bash/python/node) that wake the bot when conditions are met |
| Task table | Every unit of agent work — chat turns, heartbeat, dream, isolated cron/trigger jobs — registered live; talon ps / talon kill |
| Event bus | Typed internal pub-sub spine (task + turn lifecycle events); subsystems subscribe instead of importing each other; talon events -f |
| VFS | Unified namespace at ~/.talon/ns over workspace, skills, scripts, logs, plus /proc-style live views of the task table, event bus, and plugin registry — a real filesystem (FUSE-backed live views), so plain ls/cat and every tool just work |
| Per-chat settings | Model, effort level, and pulse toggle per conversation via inline keyboard |
| Model registry | Models discovered from the active backend at startup — new models appear in all pickers automatically |
