+## Utility Commands
+
+The `codebook utils` command group provides helper utilities for managing and inspecting your CodeBook environment.
+
+### Status
+
+```bash
+codebook utils status
+```
+
+**Purpose:** Provides a comprehensive health check and overview of your CodeBook documentation environment.
+
+**Output includes:**
+
+1. **Task Statistics**
+   - Total number of tasks in the tasks directory
+   - Breakdown by status (if tasks have status metadata)
+   - Recently created/modified tasks
+
+2. **Link Health**
+
+   Validates different types of links based on their nature:
+
+   **File References** - `[text](file.md)` or `[text](file.md#section)`
+   - Check if target file exists
+   - For section links (`#section`), verify the heading exists in the target file
+   - Report broken links with source file and line number
+   - Report broken section anchors with expected heading
+
+   **CodeBook Templates** - `` [`value`](codebook:template) ``
+   - Count total templates found
+   - Optionally verify backend connectivity
+
+   **EXEC Blocks** - `<exec lang="python">code</exec>`
+   - Validate language is supported (currently: `python`)
+   - Check Python syntax with `ast.parse()` (no execution)
+   - Verify Jupyter kernel is available
+   - Report syntax errors with file and line number
+
+   **CICADA Blocks** - `<cicada endpoint="query" param="value">...</cicada>`
+   - Validate endpoint name (`query`, `search-function`, `search-module`, `git-history`, `expand-result`, `refresh-index`, `query-jq`)
+   - Check required parameters are present for each endpoint type
+   - Optionally verify Cicada server connectivity
+   - Report invalid endpoints/params with file and line number
+
+3. **Backend Connectivity**
+   - Backend server health status (if configured)
+   - URL and response time
+
+4. **Cicada Integration**
+   - Cicada server status (if configured)
+   - Index availability
+
+**Exit codes:**
+- `0` - All checks passed
+- `1` - Warnings found (broken links, missing files)
+- `2` - Errors found (backend unreachable, critical failures)

+After completing the task, please update the task file with:
+- Description of the feature task that was requested
+- Short description of the changes that were made and why
+Include implemenentation details how the task was implemented.
+Do not include code snippets. Only describe the functional changes that were made.
+Do not remove diff lines from the task file.
+--- FEATURE TASK ---
+Implement a comprehensive status command for CodeBook that provides health checks and diagnostics for the documentation environment. The command should validate links, check code blocks, gather task statistics, and optionally verify backend/Cicada connectivity.
+
+--- NOTES ---
+The implementation expanded the original specification to include:
+- Section anchor validation for markdown links (e.g., file.md#heading)
+- Python syntax validation for EXEC blocks using ast.parse()
+- Endpoint and parameter validation for CICADA blocks
+- Proper exit codes (0=success, 1=warnings, 2=errors)
+- Optional backend/Cicada connectivity checks via flags
+
+--- SOLUTION ---
+Created a new utils module (src/codebook/utils.py) with:
+- CodeBookStatusChecker class that validates different link types based on their nature
+- StatusReport dataclass to collect and report findings with exit code logic
+- LinkValidationResult dataclass for individual validation results
+
+Added utils command group to CLI (src/codebook/cli.py) with:
+- utils status command that orchestrates all health checks
+- --check-backend and --check-cicada flags for optional connectivity tests
+- Formatted output with emoji indicators and sectioned reporting
+
+Validation implementation:
+- File references: Checks file existence and validates section anchors by parsing markdown headings and generating GitHub-style slugs
+- EXEC blocks: Validates language support (python only) and syntax using ast.parse() without executing code
+- CICADA blocks: Validates endpoint names against whitelist and checks required parameters per endpoint type
+- Backend/Cicada: Optional HTTP health checks with response time measurement
+
+Created comprehensive test suite (tests/test_utils.py) with 19 test cases covering:
+- StatusReport exit code logic
+- Task statistics gathering
+- All validation types (file links, sections, EXEC, CICADA)
+- Edge cases (missing files, syntax errors, invalid endpoints)
+
+The command successfully identified real issues in the codebase including 18 broken file links and 3 invalid CICADA blocks during initial testing.
+
+Moved UTILS.md from project root to codebook/ directory to match the documentation structure expected by the README link.
