Build with Specs. Code with Context.
Archcore is a git-native context layer for AI coding agents. It keeps specs, architecture, decisions, rules, and plans in your repository and makes that project context available as your agent works.
Start with a decision or rule your agent needs for its next task. Record it in .archcore/, review the document, and retrieve it in a later session. The same project documents are available across your connected agents.
Start using Archcore
Section titled “Start using Archcore”- Install Archcore and connect your coding agent.
- Follow the quick start to record and reuse project context.
- See what to expect during a session, including what happens automatically.
Use it in your project
Section titled “Use it in your project”| Your task | Where to go |
|---|---|
| Record a decision, plan a change, or review a branch | Commands and examples |
| Add Archcore to an agent or your own harness | Connect your agent |
| Use Archcore alongside another tool | Integrations |
| Diagnose a missing tool, hook, or document | Troubleshooting |
Understand the model
Section titled “Understand the model”Archcore supports spec-driven development and context engineering. Specs describe intended behavior; project context also includes the decisions, constraints, and rules behind that behavior.
Why Archcore explains the design choices and tradeoffs. Project context explains how documents, categories, and relations fit together.
