+# Mole AI Agent Documentation
+
+> **READ THIS FIRST**: This file serves as the single source of truth for any AI agent trying to work on the Mole repository. It aggregates architectural context, development workflows, and behavioral guidelines.
+
+## 1. Philosophy & Guidelines
+
+### Core Philosophy
+
+- **Safety First**: Never risk user data. Always use `safe_*` wrappers. When in doubt, ask.
+- **Incremental Progress**: Break complex tasks into manageable stages.
+- **Clear Intent**: Prioritize readability and maintainability over clever hacks.
+- **Native Performance**: Use Go for heavy lifting (scanning), Bash for system glue.
+
+### Eight Honors and Eight Shames
+
+- **Shame** in guessing APIs, **Honor** in careful research.
+- **Shame** in vague execution, **Honor** in seeking confirmation.
+- **Shame** in assuming business logic, **Honor** in human verification.
+- **Shame** in creating interfaces, **Honor** in reusing existing ones.
+- **Shame** in skipping validation, **Honor** in proactive testing.
+- **Shame** in breaking architecture, **Honor** in following specifications.
+- **Shame** in pretending to understand, **Honor** in honest ignorance.
+- **Shame** in blind modification, **Honor** in careful refactoring.
+
+### Quality Standards
+
+- **English Only**: Comments and code must be in English.
+- **No Unnecessary Comments**: Code should be self-explanatory.
+- **Pure Shell Style**: Use `[[ ]]` over `[ ]`, avoid `local var` assignments on definition line if exit code matters.
+- **Go Formatting**: Always run `gofmt` (or let the build script do it).
+
+## 2. Project Identity
+
+- **Name**: Mole
+- **Purpose**: A lightweight, robust macOS cleanup and system analysis tool.
+- **Core Value**: Native, fast, safe, and dependency-free (pure Bash + static Go binary).
+- **Mechanism**:
+  - **Cleaning**: Pure Bash scripts for transparency and safety.
+  - **Analysis**: High-concurrency Go TUI (Bubble Tea) for disk scanning.
+  - **Monitoring**: Real-time Go TUI for system status.
+
+## 3. Technology Stack
+
+- **Shell**: Bash 3.2+ (macOS default compatible).
+- **Go**: Latest Stable (Bubble Tea framework).
+- **Testing**:
+  - **Shell**: `bats-core`, `shellcheck`.
+  - **Go**: Native `testing` package.
+
+## 4. Repository Architecture
+
+### Directory Structure
+
+- **`bin/`**: Standalone entry points.
+  - `mole`: Main CLI wrapper.
+  - `clean.sh`, `uninstall.sh`: Logic wrappers calling `lib/`.
+- **`cmd/`**: Go applications.
+  - `analyze/`: Disk space analyzer (concurrent, TUI).
+  - `status/`: System monitor (TUI).
+- **`lib/`**: Core Shell Logic.
+  - `core/`: Low-level utilities (logging, `safe_remove`, sudo helpers).
+  - `clean/`: Domain-specific cleanup tasks (`brew`, `caches`, `system`).
+  - `ui/`: Reusable TUI components (`menu_paginated.sh`).
+- **`scripts/`**: Development tools (`run-tests.sh`, `build-analyze.sh`).
+- **`tests/`**: BATS integration tests.
+
+## 5. Key Workflows
+
+### Development
+
+1. **Understand**: Read `lib/core/` to know what tools are available.
+2. **Implement**:
+    - For Shell: Add functions to `lib/`, source them in `bin/`.
+    - For Go: Edit `cmd/app/*.go`.
+3. **Verify**: Use dry-run modes first.
+
+**Commands**:
+
+- `./scripts/run-tests.sh`: **Run EVERYTHING** (Lint, Syntax, Unit, Go).
+- `./bin/clean.sh --dry-run`: Test cleanup logic safely.
+- `go run ./cmd/analyze`: Run analyzer in dev mode.
+
+### Building
+
+- `./scripts/build-analyze.sh`: Compiles `analyze-go` binary (Universal).
+- `./scripts/build-status.sh`: Compiles `status-go` binary.
+
+### Release
+
+- Versions managed via git tags.
+- Build scripts embed version info into binaries.
+
+## 6. Implementation Details
+
+### Safety System (`lib/core/file_ops.sh`)
+
+- **Crucial**: Never use `rm -rf` directly.
+- **Use**:
+  - `safe_remove "/path"`
+  - `safe_find_delete "/path" "*.log" 7 "f"`
+- **Protection**:
+  - `validate_path_for_deletion` prevents root/system deletion.
+  - `checks` ensure path is absolute and safe.
+
+### Go Concurrency (`cmd/analyze`)
+
+- **Worker Pool**: Tuned dynamically (16-64 workers) to respect system load.
+- **Throttling**: UI updates throttled (every 100 items) to keep TUI responsive (80ms tick).
+- **Memory**: Uses Heaps for top-file tracking to minimize RAM usage.
+
+### TUI Unification
+
+- **Keybindings**: `j/k` (Nav), `space` (Select), `enter` (Action), `R` (Refresh).
+- **Style**: Compact footers ` | ` and standard colors defined in `lib/core/base.sh` or Go constants.
+
+## 7. Common AI Tasks
+
+- **Adding a Cleanup Task**:
+    1. Create/Edit `lib/clean/topic.sh`.
+    2. Define `clean_topic()`.
+    3. Register in `lib/optimize/tasks.sh` or `bin/clean.sh`.
+    4. **MUST** use `safe_*` functions.
+- **Modifying Go UI**:
+    1. Update `model` struct in `main.go`.
+    2. Update `View()` in `view.go`.
+    3. Run `./scripts/build-analyze.sh` to test.
+- **Fixing a Bug**:
+    1. Reproduce with a new BATS test in `tests/`.
+    2. Fix logic.
+    3. Verify with `./scripts/run-tests.sh`.
