Governed Workspace Standard

Centralize instructions in AGENTS.md with tool-specific adapters for Antigravity, Claude Code, Cursor, Codex, Gemini, and VS Code.

🧩

Declarative Skill OS

Validation-first skill, prompt, workflow, permission, and guardrail registries with Ed25519 signatures and policy checks.

⚡

Localhost Gateway Foundation

Mock OpenAI-compatible provider runtime, client preview configs, route planning, and local in-memory usage accounting.

🔒

Zero-Dependency Safety

Standard library Node.js (20+) architecture with approval-gated writes, bounded local logs, and zero remote tracking.

Architecture Overview ​

MultiModel Dev OS sits between developer intent, AI coding tools, and localhost gateway mock foundations:

Non-Negotiable Safety Boundaries ​

MultiModel Dev OS is designed for total transparency and local safety:

Zero Runtime Dependencies
Uses Node.js standard library built-in modules only (crypto, fs, http, path).
Approval-Gated Writes
All file mutations require explicit approval. Onboarding and planning are read-only.
Mock-Only Provider
The v4.2 gateway executes bundled mock models only. No external APIs are called.
Preview-Only Configs
Client configuration plans are preview-only. No third-party tools are modified silently.
Local Observability
Traces, metrics, and usage logs stay local, bounded, redacted, and in-memory. Zero telemetry.
Maintainer Publication
Package publishing is maintainer-controlled with strict pre-publish security checks.
