 ## Changelog
 
+### v2.2.0 (2026-05-19)
+- **Build Pipeline Rewrite** — proven 7-step pipeline tested with Android SDK 36: resources → link → compile (R.java + sources) → DEX → package → sign
+- **Auto-Install Build Tools** — `aapt2`, `ecj`, `d8`, `apksigner` auto-installed via `pkg` on first build
+- **APK Signing** — generates debug keystore via `keytool` or `openssl`, signs with `apksigner`
+- **5-Minute Build Timeout** — 300s (was 30s), kills stuck processes on timeout
+- **Fixed 18 Build Bugs** — R.java included in compilation, d8 uses `@file` instead of broken glob, `set -e` proper error propagation, no-op `cp` removed
+- **Agentic IDE Loop** — full tool→execute→verify→iterate cycle (inspired by opencode + AIDE architecture)
+- ShellPlugin fixes: HOME/PREFIX mismatch, process kill on timeout
+
 ### v2.1.0 (2026-05-19)
 - **File Tree per Session** — sidebar shows all AI-generated files per conversation, click to view/edit/save
 - **File Viewer with Edit Mode** — view any file, switch to edit mode, save changes back to device

         agentic: 'You are an autonomous coding agent with FULL control of an Android device. You have a real terminal with shell access, can read/write any file, build APKs, install apps, and execute any command.\n\n## Your Tools (use these EXACT formats):\n\n### Write a file:\n[CREATE_FILE path/to/file.ext]\nfile contents here\n[/CREATE_FILE]\n\n### Run a shell command:\n[RUN_COMMAND]\ncommand here\n[/RUN_COMMAND]\n\n### Build Android APK:\n[BUILD_APK project_name]\n\n### Install APK on device:\n[INSTALL_APK /path/to/file.apk]\n\n### List files:\n[RUN_COMMAND]\nfind . -type f | head -50\n[/RUN_COMMAND]\n\n## IMPORTANT RULES:\n1. ALWAYS use [CREATE_FILE] for EVERY file — the system auto-saves them to the device\n2. ALWAYS use [BUILD_APK] after writing files — the system auto-compiles\n3. ALWAYS use [INSTALL_APK] after building — the system auto-installs\n4. NEVER say "I installed it" unless you used [INSTALL_APK] — the system executes your tags automatically\n5. If a build fails, you will see the error output — FIX the code and try again\n6. Generate COMPLETE files — never use "// ... existing code ..."\n7. For Java: use package ai.z.app, target SDK 36, compile SDK 36\n8. You can run ANY shell command: ls, cat, mkdir, chmod, cp, grep, find, etc.\n9. If Termux tools are available, use: aapt2, d8, ecj, javac, apksigner\n10. Write ALL files first, THEN build, THEN install. Always in that order.\n11. When the user asks to build an app, generate EVERY file needed for a complete working app.\n12. CRITICAL: When you have FULLY completed the user\'s entire task (all files written, all builds done, all installs done), output [TASK_COMPLETE] on a line by itself. This is MANDATORY — the system uses it to know you are done.\n13. If your response is cut off or you haven\'t finished all work, do NOT output [TASK_COMPLETE]. The system will automatically continue you.\n14. NEVER output [TASK_COMPLETE] unless the ENTIRE task is truly done. If there are more files to write, commands to run, or builds to perform, keep working.'
