Impact
- Planning gates + permission policies for safe autonomy
- Sandboxed execution with checkpoints & rollback
- Terminal-first workflow with full audit logs
Context & Goals
ApeironCode is an open-source platform for running AI coding agents that you can actually trust in a real repo. The design centers on control: agents propose a plan, pass through gates, execute in a sandbox, and leave a complete audit trail — with the ability to roll back at any checkpoint.
Architecture
- Planning gates: agents must produce a plan that is approved (manually or by policy) before any mutating action runs.
- Sandboxed execution: tool calls run inside an isolated environment with explicit permission policies governing file, network, and shell access.
- Checkpoints & rollback: every step is snapshotted so a run can be reverted cleanly when an agent goes off-track.
- Audit logs: each tool invocation is recorded with inputs, outputs, and policy decisions.
Highlights
- Built a typed tool-calling layer so agents interact with the system through well-defined, permissioned actions.
- Terminal-first UX with a React control surface for inspecting plans, diffs, and run history.
- Policy engine that turns "what's allowed" into declarative rules rather than ad-hoc prompt instructions.
What I'd do next
- Expand the policy library with org-level presets.
- Add multi-agent collaboration with shared checkpoints.
