Loop Graph Engineer (VS Code extension)

Design agent loop graphs on a visual canvas and run them against real models (OpenAI, Anthropic, Google, OpenRouter, Ollama, or any OpenAI-compatible endpoint).

Features

• Graph builder in the sidebar or a full editor panel — "Loop Graph: Open Builder" from the command palette.
• Persistence via the extension host — projects, runs, files, and settings live in VS Code global state; API keys are stored in the OS keychain via SecretStorage.
• CORS-free model calls — requests go through the extension host, so Anthropic and local Ollama work without browser CORS issues.
• Real workspace files — attach files from your workspace to run nodes, and write run output back into the workspace.
• GitHub sign-in — uses VS Code's built-in GitHub authentication.

License

Apache 2.0 — the same terms as the rest of the Axiom repository, LICENSE included verbatim so the carve-out travels with the code.

Apache rather than MIT because MIT grants no patent rights at all. Apache 2.0 gives you an express, royalty-free patent licence for what ships here, which is the point of using a permissively licensed tool built by a company that files patents — you should not have to wonder.

Read the note at the end of LICENSE: the Two-Layer Evaluation Pattern (Teacher-Student, Kid-Parent, Doctor-Patient) is not covered, and is proprietary to Orivael Inc. Building a critic loop on this canvas is ordinary use of the tool and is fine; reimplementing that pattern is what the note is about. See TERMS_OF_SERVICE.md.
