The Protocol Layer
1Source injects a standardized .1source protocol into your repo. It serves as the authoritative interface for any AI agent interacting with your codebase.

Keep humans and AI agents aligned. 1Source generates a shared context layer from your repo so every tool - from Cursor to Claude Code - follows the same decisions, patterns, and conventions.
Standardize context across your stack
1Source injects a standardized .1source protocol into your repo. It serves as the authoritative interface for any AI agent interacting with your codebase.
Establish the "Level Playing Field." Define strict boundaries, forbidden patterns, and mandatory conventions that every engineer and agent must follow.
Prevent "Architectural Amnesia." The DECISIONS.md artifact ensures new agents respect historical context and don't re-litigate solved problems.
Cursor, Copilot, Claude, Gemini—they all read from the same .1source layer. One source of truth means consistent AI-assisted changes across every tool your team uses.
Artifacts are delivered via automated Pull Request. Engineering leads review context updates just like code, keeping documentation in perfect sync.
Standardize context across all your AI coding assistants for consistent, high-quality results.
Get StartedConnect your GitHub repo, and 1Source analyzes your codebase and commit history to extract architectural decisions, conventions, and key entry points.
Context files are delivered as a pull request - your team reviews and merges, and every AI tool now shares the same source of truth.
Extracts patterns, conventions, and decisions from your code and git history.
Context updates arrive as PRs you can review, approve, and merge.
