-## 5. Troubleshooting
+## 5. Workspace Bootstrap (MUST run before any build)
+Agents **MUST** perform these steps automatically at the start of every session before running any Gradle task. Do not wait for the user to tell you.
+
+1. **Android SDK:** `ANDROID_HOME` may not be set in agent workspaces. Detect and export it:
+   ```bash
+   # Check common macOS/Linux locations in order of preference
+   if [ -z "$ANDROID_HOME" ]; then
+     for dir in "$HOME/Library/Android/sdk" "$HOME/Android/Sdk" "/opt/android-sdk"; do
+       if [ -d "$dir" ]; then export ANDROID_HOME="$dir"; break; fi
+     done
+   fi
+   ```
+   All `./gradlew` invocations must include `ANDROID_HOME` in the environment. If the SDK cannot be found, ask the user for the path.
+
+2. **Proto submodule:** `core/proto/src/main/proto` is a Git submodule containing Protobuf definitions. It must be initialized or builds will fail with proto generation errors:
+   ```bash
+   git submodule update --init
+   ```
+
+## 6. Troubleshooting
 - **Build Failures:** Check `gradle/libs.versions.toml` for dependency conflicts.
 - **Missing Secrets:** Check `local.properties` (see Environment Setup above).
 - **JDK Version:** JDK 21 is required.
+- **SDK location not found:** See Workspace Bootstrap step 1 above.
+- **Proto generation failures:** See Workspace Bootstrap step 2 above.
 - **Configuration Cache:** Add `--no-configuration-cache` flag if cache-related issues persist.
 - **Koin Injection Failures:** Verify the KMP component is included in `app` root module wiring (`AppKoinModule`).

+- **Workspace Bootstrap (MUST run first):** Before executing any Gradle task in a new workspace, agents MUST automatically:
+  1. **Find the Android SDK** — `ANDROID_HOME` is often unset in agent worktrees. Probe `~/Library/Android/sdk`, `~/Android/Sdk`, and `/opt/android-sdk`. Export the first one found. If none exist, ask the user.
+  2. **Init the proto submodule** — Run `git submodule update --init`. The `core/proto/src/main/proto` submodule contains Protobuf definitions required for builds.
 - **Think First:** Reason through the problem before writing code. For complex KMP tasks involving multiple modules or source sets, outline your approach step-by-step before executing.
 - **Plan Before Execution:** Use the git-ignored `.agent_plans/` directory to write markdown implementation plans (`plan.md`) and Mermaid diagrams (`.mmd`) for complex refactors before modifying code.
 - **Atomic Execution:** Follow your plan step-by-step. Do not jump ahead. Use TDD where feasible (write `commonTest` fakes first).
