Runeward: Sandbox AI agents with policy gates
Runeward is a sandboxing tool for AI agents that enforces policy gates to restrict agent actions. It uses LLMs to interpret and enforce user-defined policies, solving the problem of unsafe or unintended agent behavior for developers building autonomous AI systems.

Attestor: open-source zero-trust boundary for autonomous AI agents
Attestor is an open-source execution boundary that enforces zero-trust security for autonomous AI agents. It uses LLMs to define and enforce policies that restrict agent actions, preventing unauthorized access or data leaks. This solves the problem of safely deploying autonomous agents in production environments.
Cinchor: accountability layer for AI agents with bound-before and prove-after
Cinchor is a primitive that enforces policy on AI agents before they act and provides cryptographic proof of actions afterward. It allows teams to give agents real capabilities (e.g., moving money, shipping changes) while maintaining auditability and preventing out-of-policy actions. The system mints scoped capabilities (spend cap, allowlist, expiry) and checks every action against them, refusing violations before execution; actions are hashed, signed, and anchored append-only for later verification.
Developer shares best practices from building 6 agent harnesses in 6 months
A developer recounts building six agent harnesses over six months and distills best practices from companies like Ramp, Stripe, OpenAI, and Anthropic. Key takeaways include using small agent prompts, deterministic gates, isolated environments, and managing state.
Community proposes three-stage rollout pattern for safe AI agent deployment
A Reddit user outlines a three-stage rollout pattern for AI agents to manage irreversible actions: observe only, propose actions with human approval, and execute bounded actions. The pattern addresses the challenge of deciding when an agent is allowed to act, emphasizing safety through staged permissions.
Sanbox: Isolated sandboxes for AI agents with MicroVM isolation
Sanbox is a platform that provides isolated, resumable sandboxes for running AI agents. It uses MicroVM isolation, a persistent filesystem, and a live trail of run events. The platform supports reusable templates, a CLI that works with Codex, Claude Code, Cursor, CI, or terminal, and can be self-hosted for security/compliance.
