AGENC CORE 0.14 · MIT LICENSED

One command and the agent
is in your terminal.

AgenC Core is the daemon-backed coding and agent harness. Its TUI, background agents, providers, tools, channels, budgets and sandbox share one local control plane.

WORKBENCH

A coding agent and an editor in one terminal.

Agent and Editor tabs, Alt+1 and Alt+2, in the same session.
An embedded Neovim buffer (nvim --embed): undo history, registers and plugins survive tab switches.
:AgenCAsk, :AgenCFix and :AgenCRefactor propose diffs beside the buffer; nothing lands until you accept.
Skills live in the session: /skills browses hundreds of project skills; agents auto-invoke them or you call one by name.

AUTONOMY

Plans that execute themselves, visibly and safely.

The agent works through a live todo checklist while you watch steps check off.
Permission modes gate writes and commands; approvals are one keypress, in the terminal or in a channel.
Budget-bounded execution with daemon-owned caps; interrupted writes, restarts and cancellations recover safely.

SWARM MODE

One turn, a swarm of parallel agents.

/swarm routes a big turn across delegate agents that are actually spawned, not merely described.
Each worker runs isolated with its own context, turn budget and mailbox.
Every assignment returns a structured outcome receipt; the parent reviews, verifies and integrates.

Everything under one control plane

Plan, build, test and ship from the terminal, with the safety rails on.

Daemon control planeTUI, print mode, agents and gateway are all clients of one local daemon.

Swarm orchestrationSpawn parallel delegates with budgets, mailboxes and outcome receipts.

Embedded NeovimA real nvim buffer in the workbench; falls back to the inline editor.

Background agentsFire-and-forget sessions you can attach, resume, stop and tail.

Channel gatewayTelegram, Discord, Slack, WebChat and stdio, with in-channel approvals.

Remote controlPair iOS or Android, co-drive chats and settle permissions from the phone.

Budget-bounded autonomyDaemon-owned reservations and caps across heartbeat, cron and hooks.

16 providersgrok-4.5 by default with 500k context; OpenAI, Anthropic, Ollama and more.

Grok OAuthSubscription Grok access with an X sign-in; no API key required.

Browser toolIsolated Chromium over CDP, behind an SSRF proxy by default.

Transactional patchesapply_patch with read-before-write and atomic-patch safety.

MCP, both waysConsume MCP servers or serve AgenC as one, including enterprise XAA.

Layered safetyPermission modes, OS sandbox (Seatbelt, Landlock) and security audit --fix.

Ledger, first-classVerified wallet-cli install and physically approved transfers.

Durable sessionsRollout logs and SQLite state; --continue and --resume just work.

Trajectory exportTurn real sessions into SFT and DPO training data.
