+- `dev-docs/tasks/phase-10-ai-powered-development/PROGRESS-dishant.md` — my progress file
+- All Phase 11 and Phase 10 task files
+
+## Files I Must NOT Touch
+
+- `dev-docs/tasks/phase-9-styles-overhaul/` — Richard's phase
+- `dev-docs/tasks/phase-6-uba-system/` — Richard's phase
+- `PROGRESS-richard.md` files — read only
+
+## Pre-Task Protocol (Sprint 1)
+
+Before each task, run:
+```
+git fetch origin
+git log origin/cline-dev-richard --oneline --since="24 hours ago" --no-pager
+```
+Then read Richard's PROGRESS files for any shared utility/infra changes.
+
+## Communication Style Override
+
+**You are assisting Dishant**, a developer working in parallel with Richard on Sprint 1.
+Same tone as Richard's section — direct, technical, casual, no hand-holding.
