# BroV — guide for AI coding agents

BroV is a personal, never-published fork of Coucou (github.com/Louis-CFM/coucou, MIT, imported at 83708fe). Native macOS app in `NotchBuddy/`: an animated character in the MacBook notch that shows Claude Code sessions, lets the user approve/answer from the notch, and chats — with the user's own `claude` CLI as its brain (no API key).

## Where things are
- `NotchBuddy/Sources/App/` — Mac app code. `NotchBuddy/Sources/CoucouKit/` — shared models, the character engine (`BotEngine.swift`), pills (`PillCatalog.swift`).
- `NotchBuddy/Sources/App/ClaudeCodeCLI.swift` — runs `claude -p … --output-format stream-json --resume <id>` for the chat.
- `NotchBuddy/Resources/sounds/` — WAV sounds.
- `NotchBuddy/project.yml` — XcodeGen project (never edit the `.xcodeproj` by hand; it is git-ignored and regenerated).

## Build
```
bash scripts/build.sh   # xcodegen + xcodebuild, installs ~/Applications/BroV.app, relaunches
bash scripts/render-brov.sh   # character in every state → /tmp/brov-states.png
```
DerivedData must stay outside ~/Documents (iCloud adds Finder attributes and codesign fails).
```
```

## Rules
- Personal use only: never publish to GitHub or any public place. The original Coucou name, Mochi character and icon are not used in BroV.
- Swift 6, SwiftUI + AppKit, no third-party dependencies. The character is drawn in code (`Canvas` + `TimelineView`).
- Secrets live in the Keychain, never on disk or in git.
- Never block Claude Code: if the app doesn't answer, the hook exits immediately.
- Never overwrite `~/.claude/settings.json`: dated backup, merge, write only after the user confirms.
- Never approve a Claude Code permission without an explicit click.
- When spawning `claude`, strip `CLAUDECODE` from the environment and close stdin.
- Pill IDs are stable contract values: never rename an existing pill ID.
