Initialize your repo

Run this once per repository, from the repo root. Paste your access key when prompted. It detects your coding agent automatically — a CLAUDE.md or .claude/ means Claude Code, an AGENTS.md or .opencode/ means opencode — then indexes the codebase. A few minutes for a typical repo.

To pick the agent explicitly, name it: sourceindex init opencode or sourceindex init claude opencode. If your repo has no CLAUDE.md yet, run /init in Claude Code first.

That's it — just use your agent

Open Claude Code or opencode in that repo as usual. The agent finds and uses the SourceIndex roadmap on its own; git hooks keep the index fresh as you commit. Day-to-day there is nothing to run.
