+# Feedback
+
+How to share bugs, ideas, and adoption experience for kaizen-agentic.
+
+## Quick channels
+
+| Channel | Use for |
+|---------|---------|
+| **Gitea Issues** | Bugs, features, general feedback (templates below) |
+| **`kaizen-agentic feedback`** | Print links and template guidance from the CLI |
+| **Pull requests** | Code and agent-definition contributions (see CONTRIBUTING.md) |
+| **State Hub messages** | Cross-repo coordination between custodian agents (advanced) |
+
+## Gitea issue templates
+
+Choose a template when opening a new issue:
+
+- **Bug report** — reproducible defects
+- **Feature request** — enhancements with proposed scope
+- **General feedback** — experience and adoption notes
+
+Repository: [coulomb/kaizen-agentic](https://gitea.coulomb.social/coulomb/kaizen-agentic/issues)
+
+## CLI
+
+```bash
+kaizen-agentic feedback          # human-readable channel list
+kaizen-agentic feedback --json   # machine-readable for tooling
+```
+
+## What helps us most
+
+- Python version and `kaizen-agentic --version`
+- Minimal reproduction steps for bugs
+- Which agents you used and whether memory/metrics were enabled
+- For integration issues: whether artifact-store, Helix Forge, or activity-core is involved
+
+## Privacy
+
+Do not include secrets, tokens, or private project content in public issues. Redact
+`.kaizen/` memory contents unless you intentionally share sanitized examples.
