Code Decisions: Open Source Claude Plugin Captures Technical Decisions
Code Decisions is a Claude Code plugin that addresses the problem of Claude forgetting technical decisions between sessions, whether working solo with parallel sessions or collaborating with a team. The plugin captures decisions made during normal conversation and persists them for future reference.
How It Works
When you make a technical decision in conversation with Claude—for example, saying "use raw SQL for dashboard queries" or "use Redis, Sidekiq is too heavy"—the plugin detects decision language and writes a markdown file to .claude/decisions/. Each file includes an affects field pointing to the files it governs. When anyone on the team (including future-you) edits those files, the decision automatically surfaces in their Claude session.
Key Features
- Zero configuration, zero dependencies (stdlib-only Python)
- Always advisory—provides nudges but never blocks
- Markdown files serve as the source of truth (not a database)
- Decisions commit to git and travel with the repository
- Decisions appear in pull requests
Manual Control Commands
The plugin includes a /decision command for manual control:
/decision authsearches past decisions about authentication/decision --tagsbrowses decisions by topic/decision undoreverts the last captured decision
The plugin is MIT licensed and available on GitHub at https://github.com/zimalabs/code-decisions.
