# Mosaic Standards

## Load Order

1. `~/.config/mosaic/STANDARDS.md`
2. Repository `AGENTS.md`
3. Repo-local `.mosaic/repo-hooks.sh` when present

## Session Lifecycle

- Start: `scripts/agent/session-start.sh`
- Priority scan: `scripts/agent/critical.sh`
- End: `scripts/agent/session-end.sh`

If wrappers are available, you may use:

- `mosaic-session-start`
- `mosaic-critical`
- `mosaic-session-end`

## Enforcement Rules

- Treat `~/.config/mosaic` as canonical for shared guides, tools, profiles, and skills.
- Do not edit generated project views directly when the repo defines canonical data sources.
- Pull/rebase before edits in shared repositories.
- Run project verification commands before claiming completion.
- Use non-destructive git workflow unless explicitly instructed otherwise.
