About Open Envelope

The full technical specification for the Envelope team definition format, agent structure, workspace documents, adapters, variables, secrets, and access policies., VS Code, JetBrains, and any SchemaStore-aware editor will validate *.envelope.json files automatically, no configuration needed. The Envelope team definition, the structure that describes agents, roles, hierarchy, escalation paths, required secrets, and adapters, is published as a formal, versioned open source specification. Anyone can read it, validate against it, and build tooling around it.

About Overplane

Overplane is an AI code generation and build system that verifies and safely compiles plain-language specs into working, verified code. Container-sandboxed agents, replayable builds, and multi-agent support. Overplane combines popular AI coding agents with containers, spec-driven development, and formal verification to create a safer and more reliable AI coding workflow. Overplane keeps the speed and fixes the rest in three moves: contain the agent, wrap it in a real build system, and verify the plan before the code exists.
