 # Agent Instructions
 
-This project uses **bd** (beads) for issue tracking. Run `bd onboard` to get started.
+This project has a *zero defects policy*. 
+When you are unsure about something, ALWAYS ask the user.
 
-## Quick Reference
+# Planning
 
-```bash
+we use  `yx` for planning run yx --help to see options. Invoke when the user wants to make a plan, work on something for a plan or mentions 'yak' or 'yaks'.
-bd ready              # Find available work
-bd show <id>          # View issue details
-bd update <id> --status in_progress  # Claim work
-bd close <id>         # Complete work
-bd sync               # Sync with git
-```
 
-## Landing the Plane (Session Completion)
+# Building
 
-**When ending a work session**, you MUST complete ALL steps below. Work is NOT complete until `git push` succeeds.
+This is a Phoenix Liveview monorepo, the blogging library is in blogex, the application is in 'app'. Use `make` to build and `brief` to find out more about mix. 
 
-**MANDATORY WORKFLOW:**
+# Development
+Always fix failing tests, credo issues and format isseus.
 
-1. **File issues for remaining work** - Create issues for anything that needs follow-up
+When developing new features, we apply TDD. Work Test-First, and Refactor when all tests are passing.
-2. **Run quality gates** (if code changed) - Tests, linters, builds
-3. **Update issue status** - Close finished work, update in-progress items
-4. **PUSH TO REMOTE** - This is MANDATORY:
-   ```bash
-   git pull --rebase
-   bd sync
-   git push
-   git status  # MUST show "up to date with origin"
-   ```
-5. **Clean up** - Clear stashes, prune remote branches
-6. **Verify** - All changes committed AND pushed
-7. **Hand off** - Provide context for next session
-
-**CRITICAL RULES:**
-- Work is NOT complete until `git push` succeeds
-- NEVER stop before pushing - that leaves work stranded locally
-- NEVER say "ready to push when you are" - YOU must push
-- If push fails, resolve and retry until it succeeds
 
+If you believe an issue is pre-existing, stop work, and have a conversation with the user on how to address the pre-existing issue, as well as how to prevent this in the future.
