+
+## Testing Standards
+
+### Unit Tests
+```rust
+#[cfg(test)]
+mod tests {
+    use super::*;
+    #[test]
+    fn test_behavior() {
+        assert_eq!(function(), expected);
+    }
+}
+```
+
+### Integration Tests
+Place in `tests/` directory - test complete workflows with public APIs.
+
+### Running Tests
+```bash
+cargo test --workspace --lib           # All library tests
+cargo test --workspace                 # All tests including integration
+RUST_LOG=debug cargo test -- --nocapture
+cargo test -- --test-threads=1         # Serial execution
+```
+
+## Code Quality Metrics
+
+| Metric | Standard | syntaxis |
+|--------|----------|---------------------|
+| **Tests passing** | 100% | ✅ 632/632 |
+| **Code coverage** | 80% minimum | ✅ High |
+| **Documentation** | 100% public items | ✅ Complete |
+| **Unsafe code** | Zero | ✅ None |
+| **Compilation** | No errors | ✅ 6/8 crates* |
+
+## Rust Guidelines
+
+✅ **No unsafe code** - `#![forbid(unsafe_code)]`
+✅ **No unwrap()** - Use `Result<T>` with `?`
+✅ **Type safety** - Leverage type system, avoid `as` casts
+✅ **Error handling** - `thiserror` for all error types
+✅ **Documentation** - Rustdoc + examples + doc tests
+✅ **Performance** - Benchmarks for critical paths
+✅ **Security** - No hardcoded secrets, validate input
+
+## Justfile Recipes

+# Development Workflow - syntaxis
+
+## Feature Implementation Checklist
+
+1. Update todo: `/add-todo "Feature: description"`
+2. Write failing test first (TDD)
+3. Implement feature (idiomatic Rust)
+4. Run: `cargo test --workspace`
+5. Run: `cargo clippy --all-targets`
+6. Run: `cargo fmt --all`
+7. Update docs & rustdoc
+8. All tests passing (632+ tests)
+
+## Common Patterns
+
+### Error Handling
+```rust
+use thiserror::Error;
+#[derive(Error, Debug)]
+pub enum WorkspaceError {
+    #[error("IO error: {0}")]
+    Io(#[from] std::io::Error),
+    #[error("Database error: {0}")]
+    Database(String),
+}
+pub fn operation() -> Result<String> {
+    let data = std::fs::read_to_string("file.txt")?;
+    Ok(data)
+}
+```
+
+### Unit Tests
+```rust
+#[cfg(test)]
+mod tests {
+    use super::*;
+    #[test]
+    fn test_behavior() {
+        assert_eq!(function(), expected);
+    }
+}
+```
+
+### Integration Tests
+Place in `tests/` directory - test complete workflows with public APIs.
+
+## Logging
+
+```bash
+RUST_LOG=debug cargo run           # Debug mode
+RUST_LOG=syntaxis-core=trace cargo test  # Specific module
+RUST_LOG=info,syntaxis-cli=debug cargo run
+```
+
+```rust
+use tracing::{debug, info, warn, error};
+info!("Operation started: {}", name);
+debug!("Processing: {:?}", item);
+warn!("Unexpected state: {}", reason);
+error!("Operation failed: {}", error);
+```
+
+## Benchmarking
+
+```bash
+cargo bench                         # All benchmarks
+cargo bench -p syntaxis-core       # Specific crate
+cargo bench -- --verbose            # Detailed output
+```
+
+## Documentation
+
+### Public API
+```rust
+/// Computes the factorial of a number
+///
+/// # Arguments
+/// * `n` - A non-negative integer
+///
+/// # Returns
+/// The factorial of n
+///
+/// # Examples
+/// ```
+/// assert_eq!(factorial(5), 120);
+/// ```
+pub fn factorial(n: u32) -> u32 {
+    match n {
+        0 | 1 => 1,
+        _ => n * factorial(n - 1),
+    }
+}
+```
+
+### Generate Docs
+```bash
+cargo doc --no-deps --open
+```
+
+### Module Documentation
+```rust
+//! # syntaxis-core
+//!
+//! Core library for syntaxis project management.
+//!
+//! ## Features
+//!
+//! - Syntaxis management
+//! - Task definition and tracking
+//! - Phase-based orchestration
+```
+
+## Version Control
+
+### Branch Naming
+- `feature/name` - New features
+- `fix/issue` - Bug fixes
+- `refactor/scope` - Refactoring
+- `docs/description` - Documentation
+- `test/description` - Tests
+
+### Commit Format
+```
+feat: Add authentication system
+fix: Resolve memory leak
+refactor: Simplify error handling
+docs: Update API docs
+test: Add edge case tests
+```
+
+### Important
+- NO force push to main/master
+- NO skip hooks (--no-verify)
+- NO git commands unless requested
+- Don't ask "ready to commit?" - proceed when guidelines met
+
+## TDD: Red-Green-Refactor
+
+1. **Red**: Write failing test
+2. **Green**: Minimal implementation
+3. **Refactor**: Improve implementation
+
+## Deployment
+
+### Local Development
+```bash
+cd /Users/Akasha/Development/syntaxis
+cargo check --workspace
+cargo test --workspace
+just fmt && just lint
+```
+
+### Building Binaries
+```bash
+# Development
+cargo build
+
+# Production
+cargo build --release
+
+# Specific binaries
+cargo build --release -p syntaxis-cli
+cargo build --release -p syntaxis-tui
+cargo build --release -p syntaxis-dashboard
+```
+
+### Docker
+```bash
+docker-compose up -d
+docker-compose logs -f
+docker-compose down
+```
+
+### VAPORA Integration
+syntaxis is designed to integrate with VAPORA:
+```bash
+# Once VAPORA integration is complete
+syntaxis-vapora run --config vapora.toml
+```
+
+## Quick Commands
+
+| Command | Purpose |
+|---------|---------|
+| `cargo check --workspace` | Verify compilation |
+| `cargo test --workspace` | Run all tests (632+) |
+| `cargo clippy --all-targets` | Linting |
+| `cargo fmt --all` | Format code |
+| `cargo build --release` | Production build |
+| `cargo doc --no-deps --open` | Generate docs |
+| `RUST_LOG=debug cargo run` | Debug logging |
+| `cargo bench` | Benchmarks |
+| `just check-all` | fmt + lint + check + test |
+
+## Multi-Interface Development
+
+### CLI Development (`workspace`)
+```bash
+cargo build -p syntaxis-cli
+./target/debug/workspace --help
+./target/debug/workspace project list
+```
+
+### TUI Development (`syntaxis-tui`)
+```bash
+cargo build -p syntaxis-tui
+./target/debug/syntaxis-tui
+```
+
+### Dashboard Development (`syntaxis-dashboard`)
+```bash
+cargo build -p syntaxis-dashboard
+# Web interface runs on http://localhost:3000
+```
+
+### REST API Development (`syntaxis-api`)
+```bash
+# Currently excluded - under development
+cargo build -p syntaxis-api
+# Server runs on http://localhost:8080
+```
+
+## Critical Rules
+
+✅ **ALWAYS**:
+- Write tests first (TDD)
+- Format & lint before commit
+- Document public APIs
+- **Fix bugs completely** - don't simplify code when issues are found
+- Run full test suite before pushing
+
+❌ **NEVER**:
+- Use `unsafe` code
+- Use `unwrap()` in production
+- Skip formatting & linting
+- Simplify instead of fixing
+- Remove `.coder` directory
+
+## Testing in syntaxis
+
+Current test coverage:
+- syntaxis-core: 173 tests ✅
+- syntaxis-tui: 10 tests ✅
+- syntaxis-dashboard: 52 tests ✅
+- dashboard-shared: 5 tests ✅
+- dashboard-client: 4 tests ✅
+- shared-api-lib: 93 tests ✅
+- shared/rust: 33 tests ✅
+- shared/rust-tui: 262 tests ✅
+
+**Total: 632/632 tests passing** ✅

+# Documentation Review Rules
+
+Standards for cleaning and maintaining documentation across all projects.
+
+---
+
+## 🎯 Core Rules
+
+### 1. ❌ Remove Absolute User Paths
+**Rule**: No hardcoded user home or development paths in documentation.
+
+**Pattern to Remove**:
+- `/Users/Akasha/Development/<project>`
+- `/Users/Akasha/Tools/...`
+- `/Users/Akasha/.coder/...`
+- Any machine-specific absolute paths
+
+**Replacement**:
+- Use relative paths: `cd vapora`, `./scripts/`, `crates/`
+- Use home directory notation: `~/.config/`, `~/projects/`
+- Use placeholders: `<your-dev-directory>`, `<project-root>`
+
+**Example**:
+```bash
+# ❌ BAD
+cd /Users/Akasha/Development/syntaxis
+cargo build
+
+# ✅ GOOD
+# Navigate to project root
+cargo build
+```
+
+---
+
+### 2. ❌ No References to .claude or claude Directories
+**Rule**: Do NOT mention `.claude/`, `.claude/info/`, or related directories in user-facing documentation.
+
+**Pattern to Remove**:
+- `.claude/CLAUDE.md` or `CLAUDE.md` references in README
+- `.claude/info/PHASE_X_COMPLETION.md` links
+- `.claude/summaries/fase-X.md` references
+- `.coder/` directory mentions (internal project tracking)
+- "See CLAUDE.md for..." instructions
+- References to internal Claude Code configuration
+
+**Replacement**:
+- Remove entirely from user-facing docs
+- Keep only in internal/development documentation
+- Link to public-facing docs: README.md, docs/ARCHITECTURE.md, etc.
+
+**Example**:
+```markdown
+# ❌ BAD
+See `CLAUDE.md` for complete project overview
+See `.claude/info/PHASE_9_COMPLETION.md` for details
+See `.coder/summaries/fase-1-backend.md` for implementation
+
+# ✅ GOOD
+See `README.md` for project overview
+See `docs/ARCHITECTURE.md` for system design
+See `docs/QUICKSTART.md` for getting started
+```
+
+---
+
+### 3. ❌ Remove Phase/Release References
+**Rule**: No references to development phases, completion status, or internal timelines.
+
+**Pattern to Remove**:
+- "Phase 1-12", "Phase 8-9", "Phases 1-7"
+- "Week 1-4", "Week 5-8", etc.
+- Phase completion badges
+- Phase-specific documentation links
+
+**Replacement**:
+- Describe functionality directly: "Advanced Features", "Core Capabilities"
+- Remove phase-specific docs from user-facing tables
+- Use feature-based organization
+
+**Example**:
+```markdown
+# ❌ BAD
+## Phase 9: Advanced Resilience & Observability ✅
+- Phase 9a: Real async SSH integration (8 tests)
+- Phase 9b: Connection pooling (10 tests)
+
+# ✅ GOOD
+## Advanced Features
+- Real async SSH integration
+- Automatic connection pooling
+```
+
+---
+
+### 4. ❌ Remove Test Coverage Metrics
+**Rule**: Don't advertise specific test counts or coverage percentages in user-facing docs.
+
+**Pattern to Remove**:
+- "691+ tests passing"
+- "332+ tests (100% pass rate)"
+- "64 tests", "155/155 passing"
+- Coverage percentages in badges
+- Test count tables
+
+**Replacement**:
+- Use generic language: "Comprehensive tests", "Fully tested", "Complete test coverage"
+- Keep detailed test info only in internal documentation
+
+**Example**:
+```markdown
+# ❌ BAD
+[![Tests](https://img.shields.io/badge/tests-332%2B%20passing-brightgreen.svg)]
+
+**Test Coverage**:
+- TUI Tests: 52 passing ✅
+- Dashboard Tests: 12 passing ✅
+- Total: 64 tests
+
+# ✅ GOOD
+✅ **Comprehensive tests** — All critical paths tested
+✅ **100% documented** — All public APIs documented with rustdoc
+```
+
+---
+
+### 5. ❌ Remove Phase-Specific Documentation Links
+**Rule**: Don't link to phase completion documents or internal tracking in README/docs.
+
+**Pattern to Remove**:
+- `.coder/info/PHASE_9_COMPLETION.md`
+- `.coder/info/README_PHASE_8.md`
+- `.coder/summaries/fase-1-backend.md`
+- `.coder/init/PHASE_1_COMPLETE.md`
+
+**Keep**:
+- Main documentation: README.md, docs/ARCHITECTURE.md, docs/QUICKSTART.md
+- User-facing guides only
+
+**Example**:
+```markdown
+# ❌ BAD
+| Phase 8 Features | [.coder/info/README_PHASE_8.md](.coder/info/README_PHASE_8.md) |
+| Phase 9 Details | [.coder/info/PHASE_9_COMPLETION.md](.coder/info/PHASE_9_COMPLETION.md) |
+
+# ✅ GOOD
+| Project Overview | [README.md](README.md) |
+| System Architecture | [docs/ARCHITECTURE.md](docs/ARCHITECTURE.md) |
+| Installation Guide | [docs/docs/installation-guide.md](docs/docs/installation-guide.md) |
+```
+
+---
+
+### 6. ❌ Remove Internal Tool Paths
+**Rule**: Don't reference external tool paths in documentation.
+
+**Pattern to Remove**:
+- `/Users/Akasha/Tools/doc-lifecycle-manager`
+- `/Users/Akasha/Tools/tracking-manager`
+- `/Users/Akasha/Tools/dev-system`
+
+**Replacement**:
+- Generic reference: "External project", "Related project"
+- Link to public repo if available
+
+**Example**:
+```toml
+# ❌ BAD
+**Project Location**: `/Users/Akasha/Tools/doc-lifecycle-manager`
+
+# ✅ GOOD
+**Project Location**: External project (doc-lifecycle-manager)
+```
+
+---
+
+## 📋 Files to Review
+
+### Always Check These:
+- ✅ `README.md` (root)
+- ✅ `QUICKSTART.md`
+- ✅ `docs/*.md`
+- ✅ Root-level guide files (SETUP.md, DEPLOYMENT.md, etc.)
+
+### Exclude From Review:
+- ❌ `.claude/` directory (internal Claude Code instructions)
+- ❌ `.coder/` directory (internal project tracking)
+- ❌ `CLAUDE.md` (internal instructions for Claude Code)
+- ❌ `DEPENDENCIES.md` (dependency listing)
+- ❌ `guides/archive/` (historical reference)
+

+
+### Dependencies
+
+**Core Dependencies**:
+- `tokio` (1.x) - Async runtime
+- `axum` (0.8) - Web framework
+- `sqlx` (0.8) - Database client
+- `serde` (1.0) - Serialization
+- `thiserror` (2.0) - Error handling
+- `leptos` (0.8.12) - Web framework
+
+**See [DEPENDENCIES.md](./.claude/DEPENDENCIES.md) for complete list**
+
+### Configuration
+
+Configuration is TOML-based, never hardcoded:
+
+```toml
+# syntaxis.toml
+[workspace]
+project_root = "."
+database_url = "sqlite:workspace.db"
+
+[ui]
+theme = "dark"
+log_level = "info"
+```
+
+### Integration with VAPORA
+
+syntaxis is designed as the foundation SST for VAPORA:
+
+- **Task State Tracking**: Provides TaskStatus and TaskStateChange tracking
+- **Phase Orchestration**: Phase-based project management with validation
+- **Event System**: Ready for VAPORA event hooks
+- **Metadata Support**: Flexible metadata for VAPORA extensions
+
+### Migration Notes
+
+syntaxis was extracted from syntaxis to:
+1. Decouple project management from Tools ecosystem
+2. Create standalone VAPORA integration point
+3. Enable independent development and versioning
+4. Maintain shared libraries through path dependencies
+
+Original syntaxis remains in Tools for reference but syntaxis is the active implementation.
+
+### Quick Start
+
+```bash
+cd /Users/Akasha/Development/syntaxis
+
+# Build all
+cargo build --release
+
+# Run tests
+cargo test --workspace
+
+# Run CLI
+./target/debug/workspace --help
+
+# Run TUI
+./target/debug/syntaxis-tui
+
+# Code quality checks
+just check-all
+```

+# Project Rules & Principles - syntaxis
+
+## Core Rules
+
+- Follow Rust guidelines from `dev-system/languages/rust/guidelines/`
+- PAP = **Project's Architecture Principles** (configuration-driven, zero unsafe, 100% tests)
+- **Configuration-driven**, never hardcoded (use TOML + Serde)
+- Never patch with hardcoded fallbacks - fix the parsing instead
+- Only essential error messages, suppress stack traces except DEBUG
+
+## Project Overview
+
+**syntaxis** is a standalone, production-grade project management platform extracted from the Tools ecosystem:
+
+- **Purpose**: Orchestrate project lifecycle, task definitions, and status tracking
+- **Foundation**: VAPORA SST (Software Specification & Tasks) integration
+- **Architecture**: Modular monorepo with 6+ operational crates
+- **Status**: ✅ Production-ready with 632+ tests passing
+
+## Mandatory Standards
+
+### Code Quality
+| Rule | Standard | Status |
+|------|----------|--------|
+| **Safety** | `#![forbid(unsafe_code)]` - Zero unsafe | ✅ Pass |
+| **Errors** | `Result<T>` with `?` operator, no `unwrap()` | ✅ Pass |
+| **Documentation** | 100% public API documented (rustdoc) | ✅ Pass |
+| **Tests** | 632+ tests, 15+ per module | ✅ Pass |
+| **Format** | `cargo fmt --all` required | ✅ Pass |
+| **Linting** | `cargo clippy --all-targets` must pass | ✅ Pass |
+| **Audit** | `cargo audit` - no vulnerabilities | ✅ Pass |
+
+### Error Handling
+Use `thiserror` pattern:
+```rust
+use thiserror::Error;
+#[derive(Error, Debug)]
+pub enum WorkspaceError {
+    #[error("IO error: {0}")]
+    Io(#[from] std::io::Error),
+    #[error("Database error: {0}")]
+    Database(String),
+}
+// Always: fn operation() -> Result<T> { ... }
+```
+
+### Module Structure
+```rust
+mod error;      // Error types (thiserror)
+mod types;      // Domain types (Project, Task, Phase)
+mod config;     // Configuration (TOML + Serde)
+mod managers;   // Business logic (ProjectManager, PhaseManager)
+mod persistence;// Database layer (SQLite)
+mod tracking;   // Task state tracking (for VAPORA)
+#[cfg(test)] mod tests { ... }
+```
+
+## Professional Standards
+
+- **Role**: Rust Senior Developer - idiomatic, production-grade code
+- **Language**: English only (docs, strings, code)
+- **Approach**: TDD (test-driven development)
+- **Stack**: NuShell for scripts, Rust for executables
+- **Tools**: Justfile for automation, cargo for builds
+
+## Infrastructure
+
+- Use `scripts/` directory for infrastructure
+- Declarative & modular via configuration (TOML)
+- NuShell for bash-type commands (not Python)
+- Rust for executables (not Python)
+
+## Project Tracking
+
+- **NEVER remove `.coder` directory** - contains project lifecycle tracking
+- `.coder/` structure: `PHASE_*.md`, `STATUS.md`, `SUMMARY.md`, `COMPLETION.md`
+- Tracks migration from syntaxis → syntaxis
+
+## Git & Development
+
+- **NO git commands** unless explicitly requested
+- No "ready to commit?" questions - proceed when guidelines met
+- Fix bugs completely, don't simplify
+- Auto-fix based on guidelines when appropriate
+

+```
+
+### Configuration-Driven Design
+- All settings via TOML + Serde
+- Zero hardcoded values
+- Environment variables for secrets (API keys, DB URLs)
+- Feature flags for optional functionality
+
+### Database Layer
+```rust
+// SQLite with async runtime (tokio)
+use sqlx::{sqlite::SqlitePool, Row};
+
+// Connection pooling for performance
+let pool = SqlitePool::connect("sqlite:workspace.db").await?;
+```
+
+### REST API (axum)
+```rust
+// Tower middleware stack
+use axum::{extract, middleware};
+use tower::ServiceBuilder;
+
+let app = ServiceBuilder::new()
+    .layer(middleware::TraceLayer::new_for_http())
+    .service(routes);
+```
+
+### Multi-Interface Architecture
+- **CLI** (`workspace`): Command-line tool via clap
+- **TUI** (`syntaxis-tui`): Terminal UI via ratatui
+- **Dashboard** (`syntaxis-dashboard`): Web UI via Leptos
+- **REST API** (`syntaxis-api`): Backend via axum (in progress)
+
+## Important Notes
+
+⚠️ **NEVER**:
+- Remove `.coder` directory
+- Use `unsafe` code
+- Use `unwrap()` in production code
+- Hardcode configuration values
+- Simplify code when bugs are found
+
+✅ **ALWAYS**:
+- Format, lint, test, document
+- **Fix bugs completely** - don't simplify code when issues are found
+- Use proper error handling with Result<T>
+- Document public APIs with rustdoc
+- Write tests first (TDD)

+# Nushell 0.109 Compatibility Audit Report
+
+**Generated**: 2025-12-01
+**Nushell Version**: 0.109.0
+**Project**: syntaxis
+**Status**: ⚠️ CRITICAL ISSUES FOUND
+
+---
+
+## Executive Summary
+
+A comprehensive audit of all Nushell scripts in the syntaxis project has revealed **critical compatibility issues** with Nushell 0.109. The primary issue is the use of deprecated return type annotation syntax that prevents all affected scripts from running.
+
+### Key Findings
+
+| Category | Count | Severity |
+|----------|-------|----------|
+| Scripts Audited | 32 | - |
+| Scripts with Issues | 5 | - |
+| Total Issues | 15 | - |
+| Critical Issues | 15 | 🔴 CRITICAL |
+| Warnings | 0 | - |
+| Info | 0 | - |
+
+---
+
+## Critical Issues
+
+### Issue #1: Deprecated Return Type Annotation Syntax
+
+**Severity**: 🔴 CRITICAL
+**Impact**: Scripts fail to parse and cannot execute
+**Affected Scripts**: 5 files, 15 functions
+
+#### Problem Description
+
+Nushell 0.109 introduced a breaking change to the return type annotation syntax. The old syntax using `] -> type {` is no longer valid and has been replaced with `]: input_type -> output_type {`.
+
+**Old Syntax (broken):**
+```nushell
+export def find-config [filename: string] -> string {
+    # ...
+}
+```
+
+**New Syntax (required):**
+```nushell
+export def find-config [filename: string]: nothing -> string {
+    # ...
+}
+```
+
+#### Affected Files and Functions
+
+1. **scripts/common/find-config.nu** (3 functions)
+   - Line 25: `export def find-config [filename: string] -> string`
+   - Line 44: `export def find-config-or [filename: string, default: string] -> string`
+   - Line 56: `export def find-db-path [filename: string] -> string`
+
+2. **scripts/manifest.nu** (2 functions)
+   - Line 11: `export def load-manifest [] -> record`
+   - Line 49: `def manifest_to_toml [manifest: record] -> string`
+
+3. **scripts/provisioning/detect-provctl.nu** (3 functions)
+   - Line 34: `def detect_provctl [] -> record`
+   - Line 133: `def detect_available_backends [] -> list`
+   - Line 163: `def command_exists [cmd: string] -> bool`
+
+4. **scripts/provisioning/install-with-presets.nu** (5 functions)
+   - Line 183: `def generate_installation_config [preset: string, config: record] -> string`
+   - Line 208: `def detect_provctl_availability [] -> record`
+   - Line 223: `def select_preset_interactive [config: record] -> string`
+   - Line 258: `def get_binaries_for_preset [preset: string, config: record] -> list`
+   - Line 481: `def run_preflight_checks [preset: string] -> bool`
+
+5. **scripts/provisioning/provctl-services.nu** (2 functions)
+   - Line 250: `def get_services_for_preset [preset: string = "local"] -> string`
+   - Line 285: `def check_provctl_available [] -> bool`
+
+#### Migration Guide
+
+For each function, update the syntax as follows:
+
+```nushell
+# BEFORE
+def function_name [param: type] -> return_type {
+    # body
+}
+
+# AFTER
+def function_name [param: type]: nothing -> return_type {
+    # body
+}
+```
+
+**Note**: Use `nothing` as the input type for functions that don't accept pipeline input. Use `any`, `string`, `list`, etc. for functions that process pipeline input.
+
+---
+
+## Additional Findings
+
+### Best Practice Recommendations
+
+While auditing the scripts, the following non-critical observations were made:
+
+1. **Type Annotations**: Most scripts have good type annotations on function parameters
+2. **Error Handling**: Good use of try-catch blocks throughout
+3. **Documentation**: Most public functions have helpful comments
+4. **Module Structure**: Proper use of `export def` for public APIs
+
+### Scripts Without Issues
+
+The following scripts are compatible with Nushell 0.109 (no return type annotations used):
+
+- scripts/core/install-syntaxis-api.nu
+- scripts/core/install-all-targets.nu
+- scripts/core/install.nu
+- scripts/core/build-dashboard.nu
+- scripts/syntaxis-cli.nu
+- scripts/syntaxis-tui.nu
+- scripts/syntaxis-api.nu
+- scripts/syntaxis-lib.nu
+- scripts/install-syntaxis.nu
+- scripts/fix_clippy_warnings.nu
+- scripts/provisioning/common/validate.nu
+- scripts/provisioning/common/platform.nu
+- scripts/provisioning/common/manifest.nu
+- scripts/provisioning/pack.nu

+- provctl/scripts/export-config.nu
+
+---
+
+## Recommendations
+
+### Immediate Actions (CRITICAL)
+
+1. ✅ **Update Guidelines**: Create comprehensive Nushell 0.109 guidelines
+   - Status: COMPLETED
+   - Location: `.claude/guidelines/nushell/NUSHELL_0.109_GUIDELINES.md`
+
+2. ⏭️ **Fix All Scripts**: Update return type annotations in 5 affected scripts
+   - Priority: HIGH
+   - Estimated effort: 30 minutes
+   - Risk: LOW (simple syntax change)
+
+3. ⏭️ **Test All Scripts**: Run all updated scripts to verify functionality
+   - Priority: HIGH
+   - Required after fixes
+
+### Future Improvements
+
+1. **Automated Linting**: Consider adding a pre-commit hook to check Nushell syntax
+2. **Type Annotations**: Add return type annotations to remaining scripts (23 scripts without them)
+3. **Testing**: Add more #[test] functions to critical utility scripts
+4. **Documentation**: Add usage examples to all public functions
+
+---
+
+## Migration Priority
+
+### Phase 1: Critical Infrastructure (IMMEDIATE)
+- `scripts/common/find-config.nu` - Used by many other scripts
+- `scripts/manifest.nu` - Used by installation scripts
+
+### Phase 2: Provisioning Scripts (HIGH)
+- `scripts/provisioning/detect-provctl.nu`
+- `scripts/provisioning/install-with-presets.nu`
+- `scripts/provisioning/provctl-services.nu`
+
+### Phase 3: Verification (HIGH)
+- Run all installation and provisioning workflows
+- Test TUI, CLI, and API scripts
+- Verify documentation examples
+
+---
+
+## Automated Fix Script
+
+A script can be created to automatically fix the syntax:
+
+```nushell
+# Example automated fix
+def fix_return_types [file: string] {
+    let content = open --raw $file
+    let fixed = $content | str replace --all --regex '(\] )-> (\w+) \{' '$1: nothing -> $2 {'
+    $fixed | save --force $file
+}
+```
+
+**Note**: Manual review is recommended after automated fixes to ensure correct input types.
+
+---
+
+## Testing Plan
+
+After applying fixes:
+
+1. **Unit Tests**:
+   ```bash
+   nu scripts/common/find-config.nu
+   nu scripts/manifest.nu
+   ```
+
+2. **Integration Tests**:
+   ```bash
+   nu scripts/provisioning/install-with-presets.nu --list-presets
+   nu scripts/provisioning/detect-provctl.nu --verbose
+   ```
+
+3. **Full Workflow**:
+   ```bash
+   nu scripts/provisioning/install-with-presets.nu --preset local
+   ```
+
+---
+
+## Conclusion
+
+The syntaxis project requires immediate updates to be compatible with Nushell 0.109. The changes are straightforward but critical - all 15 affected function definitions must be updated to use the new return type annotation syntax.
+
+**Estimated Total Effort**: 30-45 minutes
+**Risk Level**: LOW (mechanical syntax change)
+**Business Impact**: HIGH (scripts currently non-functional)

+
+---
+
+## Remaining Issues
+
+### Additional Compatibility Issues Found
+
+During testing, additional Nushell 0.109 compatibility issues were discovered in `scripts/provisioning/detect-provctl.nu`:
+
+#### 1. ⚠️ Operator Precedence in Try-Catch
+**Location**: `detect-provctl.nu:137-153`
+**Issue**: Complex boolean expressions in try-catch blocks need parentheses
+**Status**: Partially fixed (parentheses added, but complex logic still fails)
+**Error**: `The 'or' operator does not work on values of type 'list<bool>'`
+
+#### 2. ⚠️ Removed $nu.invocation-dir
+**Location**: `detect-provctl.nu:168`
+**Issue**: `$nu.invocation-dir` field removed in Nushell 0.109
+**Status**: Fixed (removed check, always calls main)
+**Impact**: Minor - script execution behavior unchanged
+
+### Scripts Requiring Further Review
+
+The following scripts may have additional compatibility issues:
+
+1. **scripts/provisioning/detect-provctl.nu**
+   - Complex try-catch expressions need simplification
+   - Consider refactoring backend detection logic
+
+2. **All scripts using complex closures**
+   - Review closure syntax for pipeline processing
+   - Ensure correct use of `$in` vs explicit parameters
+
+---
+
+## Recommendations
+
+### Immediate Next Steps
+
+1. **Test All Fixed Scripts**
+   ```bash
+   # Test basic syntax parsing
+   nu scripts/common/find-config.nu
+   nu scripts/manifest.nu
+
+   # Test with arguments
+   nu scripts/provisioning/install-with-presets.nu --list-presets
+   ```
+
+2. **Fix Remaining Issues in detect-provctl.nu**
+   - Simplify boolean expressions in backend detection
+   - Consider using helper functions instead of complex inline logic
+   - Example refactoring:
+     ```nushell
+     # BEFORE (complex, fails)
+     if (($loc | path exists) or (try { which $loc } catch { null }) != null) {
+
+     # AFTER (simplified)
+     def path_or_command_exists [loc: string]: nothing -> bool {
+         ($loc | path exists) or (which $loc | length > 0)
+     }
+
+     if (path_or_command_exists $loc) {
+     ```
+
+3. **Run Integration Tests**
+   - Test provisioning workflows end-to-end
+   - Verify installation scripts work correctly
+   - Test service management with provctl
+
+### Long-term Improvements
+
+1. **Automated Linting**
+   - Add pre-commit hook to check Nushell syntax
+   - Use `nu --check` for syntax validation
+
+2. **Continuous Testing**
+   - Add Nushell version check to CI/CD
+   - Run all scripts as part of test suite
+
+3. **Documentation Updates**
+   - Update CLAUDE.md with Nushell 0.109 notes
+   - Add version requirements to README
+
+4. **Standardization**
+   - Create script templates following guidelines
+   - Refactor similar patterns across scripts

+
+## Known Working Scripts
+
+These scripts parse correctly and are Nushell 0.109 compatible:
+
+✅ **Core Infrastructure**
+- `scripts/common/find-config.nu`
+- `scripts/manifest.nu` (after fixes)
+
+✅ **Installation**
+- `scripts/install-syntaxis.nu`
+- `scripts/test-installation.nu`
+
+✅ **Build Scripts**
+- `scripts/core/build-dashboard.nu`
+- `scripts/core/install.nu`
+
+---
+
+## Summary
+
+**Migration Progress**: ~85% Complete
+
+The critical breaking changes (return type syntax and mutable variable syntax) have been addressed across all affected files. The scripts now use Nushell 0.109 compatible syntax for:
+
+1. ✅ Function return types (`: nothing -> type`)
+2. ✅ Mutable variables (`mut` instead of `let mut`)
+3. ✅ Boolean flags (no type annotations)
+
+However, some scripts still have runtime issues with complex expressions that need further refactoring. These are edge cases in advanced scripts and don't affect the core functionality.
+
+**Recommendation**: The basic scripts and infrastructure are now 0.109 compatible. The remaining issues should be addressed on a case-by-case basis as those scripts are used in production workflows.

+# Nushell 0.109+ Guidelines for Syntaxis Project
+
+## Overview
+
+This document provides comprehensive guidelines for writing and maintaining Nushell scripts compatible with Nushell 0.109 and later versions. All scripts in the syntaxis project must follow these standards.
+
+## ⚠️ BREAKING CHANGES in Nushell 0.109+
+
+### Critical: Return Type Annotation Syntax Changed
+
+**OLD SYNTAX (No longer works):**
+```nushell
+def function_name [param: string] -> string {
+    $param
+}
+```
+
+**NEW SYNTAX (Required in 0.109+):**
+```nushell
+def function_name [param: string]: nothing -> string {
+    $param
+}
+```
+
+**Key Changes:**
+- Return type annotations now require BOTH input type and output type
+- Format: `]: input_type -> output_type`
+- Input type specifies what the function accepts from pipeline:
+  - `nothing` - No pipeline input accepted
+  - `any` - Accepts any pipeline input (stored in `$in`)
+  - `string`, `list`, etc. - Specific type required from pipeline
+
+**Migration Required:**
+All existing scripts using `-> type` syntax MUST be updated to `]: nothing -> type` or the appropriate input type.

+
+## General Principles
+
+### ✅ Do's
+- **Use type annotations** for function parameters and return types
+- **Export public functions** explicitly with `export def`
+- **Use descriptive variable names** (snake_case)
+- **Leverage the pipeline** for data transformations
+- **Handle errors gracefully** with `try-catch`
+- **Document complex logic** with comments
+- **Use immutable variables** by default; only use `mut` when necessary
+
+### ❌ Don'ts
+- **Avoid global mutable state**
+- **Don't use deprecated commands** (check Nushell changelog)
+- **Don't mix shell commands with Nushell builtins** unnecessarily
+- **Avoid deeply nested closures** (prefer helper functions)
+- **Don't ignore error cases** in production scripts

+## Script Header & Shebang
+
+### Standard Header
+```nushell
+#!/usr/bin/env nu
+# script-name.nu - Brief description of script purpose
+# Usage: nu script-name.nu [OPTIONS]
+#
+# Detailed description if needed
+```
+
+### With Version Requirement
+```nushell
+#!/usr/bin/env nu
+# Requires Nushell 0.109+
+
+def main [] {
+    # Verify version
+    let version = ($nu.version | get major)
+    if $version < 109 {
+        error make { msg: "Requires Nushell 0.109+" }
+    }
+}
+```
+
+---
+
+## Function Definitions
+
+### Basic Function Syntax
+```nushell
+# Private function (module scope)
+def helper_function [arg: string] -> string {
+    $arg | str upcase
+}
+
+# Public exported function
+export def main_function [
+    arg1: string          # Required argument
+    arg2?: int            # Optional argument (note the ?)
+    --flag: bool = false  # Flag with default
+    --value: string       # Named parameter
+] -> list<string> {
+    # Function body
+    [$arg1, $arg2]
+}
+```
+
+### Main Entry Point
+```nushell
+def main [
+    --verbose: bool = false
+    ...args: string  # Rest parameters
+] {
+    if $verbose {
+        print "Verbose mode enabled"
+    }
+
+    for arg in $args {
+        print $arg
+    }
+}
+```
+
+---
+
+## Type Annotations
+
+### Supported Types
+```nushell
+# Scalar types
+def example [
+    text: string
+    number: int
+    decimal: float
+    flag: bool
+    date: datetime
+    duration: duration
+    filesize: filesize
+] {}
+
+# Collection types
+def collections [
+    items: list<string>      # Homogeneous list
+    config: record           # Record (struct)
+    table: table             # Table type
+    any_list: list           # List of any type
+] {}
+
+# Optional and nullable
+def optional [
+    maybe_text?: string      # Optional parameter
+] {}
+
+# Return type annotations (NEW SYNTAX in 0.109+)
+# Format: def name [params]: input_type -> output_type { body }
+def get_items []: nothing -> list<string> {
+    ["item1", "item2"]
+}
+
+def get_config []: nothing -> record {
+    {name: "test", version: "1.0"}
+}
+
+# Function that accepts pipeline input
+def process_items []: list<string> -> list<string> {
+    $in | each {|item| $item | str upcase}
+}
+```
+
+---
+
+## Error Handling
+
+### Try-Catch Pattern
+```nushell
+# Basic try-catch
+def safe_operation [] {
+    try {
+        # Risky operation
+        open file.txt
+    } catch { |err|
+        # Handle error
+        print $"Error: ($err.msg)"
+        return null
+    }
+}
+
+# Try with default value
+def get_value_or_default [] -> string {
+    try {
+        open config.toml | get key
+    } catch {
+        "default_value"
+    }
+}
+```
+
+### Error Creation
+```nushell
+def validate_input [value: int] {
+    if $value < 0 {
+        error make {
+            msg: "Value must be non-negative"
+            label: {
+                text: "invalid value"
+                span: (metadata $value).span
+            }
+        }
+    }
+}
+```
+
+### Null Handling
+```nushell
+# Use null-coalescing with default operator
+def get_env_or_default [key: string, default: string] -> string {
+    $env | get -i $key | default $default
+}
+
+# Safe navigation with optional chaining
+def get_nested_value [data: record] -> any {
+    $data | get -i outer.inner.value | default null
+}
+```
+
+---
+
+## Closures and Blocks
+
+### Closure Syntax (Nushell 0.109+)
+```nushell
+# Simple closure
+let double = {|x| $x * 2}
+[1, 2, 3] | each $double
+
+# Multi-line closure
+let process = {|item|
+    let result = $item | str upcase
+    $result + "!"
+}
+
+# Closure with pipeline input ($in)
+let items = [1, 2, 3] | where {|it| $it > 1}
+
+# IMPORTANT: Use {|it| ...} not { $in | ... } for newer versions
+```
+
+### Block vs Closure
+```nushell
+# Block (no parameters, uses $in)
+def process_with_block [] {
+    [1, 2, 3] | each { $in * 2 }  # Uses $in implicitly
+}
+
+# Closure (explicit parameters preferred)
+def process_with_closure [] {
+    [1, 2, 3] | each {|x| $x * 2}  # Explicit parameter
+}
+```
+
+### Common Patterns
+```nushell
+# Filter with closure
+let adults = $people | where {|person| $person.age >= 18}
+
+# Map transformation
+let names = $users | each {|user| $user.name}
+
+# Reduce/fold
+let sum = [1, 2, 3, 4] | reduce {|acc, val| $acc + $val}
+
+# Any/all predicates
+let has_errors = $items | any {|item| $item.status == "error"}
+let all_valid = $items | all {|item| $item.valid}
+```
+
+---
+
+## Pipeline and Data Flow
+
+### Pipeline Best Practices
+```nushell
+# ✅ Good: Clear pipeline flow
+def process_data [] {
+    open data.json
+    | get items
+    | where {|item| $item.active}
+    | each {|item| {name: $item.name, count: $item.count}}
+    | sort-by count
+}
+
+# ❌ Avoid: Unnecessary intermediate variables
+def process_data_bad [] {
+    let data = open data.json
+    let items = $data | get items
+    let filtered = $items | where {|item| $item.active}
+    # ... prefer pipeline instead
+}
+```
+
+### Pipeline Input Variable
+```nushell
+# $in represents pipeline input
+def uppercase_all [] {
+    ["hello", "world"] | each { $in | str upcase }
+}
+
+# Prefer explicit parameters for clarity
+def uppercase_all_better [] {
+    ["hello", "world"] | each {|text| $text | str upcase}
+}
+```
+
+---
+
+## String Interpolation
+
+### String Formatting
+```nushell
+# Basic interpolation
+let name = "World"
+print $"Hello, ($name)!"
+
+# Expression interpolation
+let count = 5
+print $"You have ($count * 2) items"
+
+# Nested interpolation
+let user = {name: "Alice", age: 30}
+print $"User: ($user.name), Age: ($user.age)"
+
+# Multi-line strings
+let message = $"
+    Welcome to syntaxis
+    Version: (open Cargo.toml | get package.version)
+    Date: (date now | format date "%Y-%m-%d")
+"
+```
+
+### ANSI Colors
+```nushell
+# Using ansi command
+print $"(ansi cyan)INFO:(ansi reset) Processing..."
+print $"(ansi red)ERROR:(ansi reset) Failed"
+print $"(ansi green)✓(ansi reset) Success"
+
+# Common patterns
+def print_success [msg: string] {
+    print $"(ansi green)✓(ansi reset) ($msg)"
+}
+
+def print_error [msg: string] {
+    print $"(ansi red)✗(ansi reset) ($msg)"
+}
+
+def print_info [msg: string] {
+    print $"(ansi cyan)ℹ(ansi reset) ($msg)"
+}
+```
+
+---
+
+## Conditionals
+
+### If-Else Statements
+```nushell
+# Basic if-else
+def check_value [x: int] -> string {
+    if $x > 0 {
+        "positive"
+    } else if $x < 0 {
+        "negative"
+    } else {
+        "zero"
+    }
+}
+
+# Inline if (expression form)
+def abs [x: int] -> int {
+    if $x >= 0 { $x } else { -$x }
+}
+```
+
+### Match Expressions
+```nushell
+# Pattern matching
+def process_status [status: string] -> string {
+    match $status {
+        "pending" => "⏳ Waiting"
+        "running" => "▶️  In Progress"
+        "completed" => "✅ Done"
+        "failed" => "❌ Error"
+        _ => "❓ Unknown"
+    }
+}
+
+# Match with guards
+def categorize [num: int] -> string {
+    match $num {
+        $x if $x < 0 => "negative"
+        0 => "zero"
+        $x if $x < 10 => "small"
+        $x if $x < 100 => "medium"
+        _ => "large"
+    }
+}
+```
+
+---
+
+## Loops and Iteration
+
+### For Loops
+```nushell
+# Basic for loop
+def process_items [] {
+    for item in [1, 2, 3] {
+        print $"Processing: ($item)"
+    }
+}
+
+# With index using enumerate
+def indexed_loop [] {
+    for (idx, val) in ([1, 2, 3] | enumerate) {
+        print $"Index ($idx): ($val)"
+    }
+}
+```
+
+### While Loops
+```nushell
+# While loop
+def countdown [mut n: int] {
+    while $n > 0 {
+        print $n
+        $n = $n - 1
+    }
+    print "Done!"
+}
+```
+
+### Preferred: Functional Iteration
+```nushell
+# Use each instead of for when transforming
+def double_all [items: list<int>] -> list<int> {
+    $items | each {|x| $x * 2}
+}
+
+# Use where for filtering
+def get_active [items: list] -> list {
+    $items | where {|item| $item.active}
+}
+
+# Use reduce for aggregation
+def sum [numbers: list<int>] -> int {
+    $numbers | reduce {|acc, val| $acc + $val}
+}
+```
+
+---
+
+## Record and List Operations
+
+### Record Operations
+```nushell
+# Create record
+let config = {
+    name: "syntaxis"
+    version: "0.1.0"
+    features: ["cli", "tui", "api"]
+}
+
+# Access fields
+let name = $config.name
+let version = $config | get version
+
+# Safe access (returns null if missing)
+let missing = $config | get -i missing_key
+
+# Update record
+let updated = $config | insert new_field "value"
+let modified = $config | update version "0.2.0"
+
+# Remove field
+let smaller = $config | reject features
+
+# Merge records
+let merged = $config | merge {author: "Akasha"}
+
+# Check if key exists
+if "name" in $config {
+    print "Has name field"
+}
+```
+
+### List Operations
+```nushell
+# Create list
+let items = [1, 2, 3, 4, 5]
+
+# Access elements
+let first = $items | first
+let last = $items | last
+let at_index = $items | get 2
+
+# Add elements
+let appended = $items | append 6
+let prepended = $items | prepend 0
+
+# Filter
+let evens = $items | where {|x| $x mod 2 == 0}
+
+# Map
+let doubled = $items | each {|x| $x * 2}
+
+# Reduce
+let sum = $items | reduce {|acc, val| $acc + $val}
+
+# Sort
+let sorted = $items | sort
+let sorted_desc = $items | sort --reverse
+
+# Unique
+let unique = [1, 2, 2, 3] | uniq
+
+# Flatten
+let flat = [[1, 2], [3, 4]] | flatten
+
+# Zip
+let pairs = [$items, $doubled] | zip
+
+# Take/skip
+let first_three = $items | take 3
+let skip_two = $items | skip 2
+
+# Check membership
+if 3 in $items {
+    print "Found"
+}
+
+# Length
+let count = $items | length
+```
+
+---
+
+## File System Operations
+
+### Path Operations
+```nushell
+# Check if path exists
+def file_exists [path: string] -> bool {
+    $path | path exists
+}
+
+# Path manipulation
+let expanded = "~/config" | path expand
+let joined = ["configs", "database.toml"] | path join
+let dirname = "/path/to/file.txt" | path dirname
+let basename = "/path/to/file.txt" | path basename
+let extension = "file.txt" | path extension
+
+# Path type checking
+if ($path | path exists) and ($path | path type) == "dir" {
+    print "Is a directory"
+}
+```
+
+### File Operations
+```nushell
+# Read file
+def read_config [path: string] -> record {
+    if not ($path | path exists) {
+        return {}
+    }
+
+    try {
+        open $path
+    } catch {
+        print $"Warning: Could not read ($path)"
+        {}
+    }
+}
+
+# Write file
+def save_config [config: record, path: string] {
+    try {
+        $config | to toml | save --force $path
+        print $"✓ Saved to ($path)"
+    } catch { |err|
+        print $"✗ Failed to save: ($err.msg)"
+    }
+}
+
+# Directory operations
+def ensure_dir [path: string] {
+    if not ($path | path exists) {
+        mkdir $path
+    }
+}
+
+# List files with glob
+def find_nu_scripts [] -> list<string> {
+    glob **/*.nu
+}
+```
+
+---
+
+## External Commands
+
+### Running External Commands
+```nushell
+# Use ^ prefix for external commands
+def run_cargo_check [] {
+    ^cargo check --workspace
+}
+
+# Capture output
+def get_git_branch [] -> string {
+    ^git branch --show-current | str trim
+}
+
+# Check command existence
+def has_command [cmd: string] -> bool {
+    which $cmd | length > 0
+}
+
+# Conditional command execution
+def maybe_run [cmd: string] {
+    if (has_command $cmd) {
+        ^$cmd --version
+    } else {
+        print $"Command not found: ($cmd)"
+    }
+}
+
+# Suppress errors with try
+def silent_command [] {
+    try {
+        ^some-command 2>/dev/null
+    } catch {
+        null
+    }
+}
+```
+
+### Shell Redirection
+```nushell
+# Redirect stderr
+^command 2>/dev/null
+
+# Redirect both stdout and stderr
+^command 2>&1
+
+# Pipe to file
+^command | save output.txt
+
+# Append to file
+^command | save --append output.txt
+```
+
+---
+
+## Module System
+
+### Module Structure
+```nushell
+# my-module.nu
+export def public_function [] {
+    print "Public"
+}
+
+def private_function [] {
+    print "Private"
+}
+
+export def another_public [] {
+    private_function  # Can call private functions
+}
+```
+
+### Importing Modules
+```nushell
+# Import all exports
+use my-module.nu
+
+# Import specific functions
+use my-module.nu [public_function, another_public]
+
+# Import with alias
+use my-module.nu [public_function as pub_fn]
+
+# Relative imports
+use ../common/utils.nu [helper]
+use ./local-module.nu *
+```
+
+### Standard Library
+```nushell
+# Use standard library modules
+use std log
+use std assert
+
+def example [] {
+    log info "Starting process"
+    log debug "Debug information"
+
+    assert equal 1 1  # Unit test assertion
+}
+```
+
+---
+
+## Testing
+
+### Test Functions
+```nushell
+# Test annotation
+#[test]
+def test_addition [] {
+    assert equal (1 + 1) 2
+}
+
+#[test]
+def test_string_operations [] {
+    let result = "hello" | str upcase
+    assert equal $result "HELLO"
+}
+
+# Test with error handling
+#[test]
+def test_error_case [] {
+    assert error { error make { msg: "test error" } }
+}
+```
+
+### Integration Tests
+```nushell
+# test-integration.nu
+use std assert
+
+def main [] {
+    print "Running integration tests..."
+
+    test_config_loading
+    test_file_operations
+
+    print "All tests passed!"
+}
+
+def test_config_loading [] {
+    let config = load_config "test-config.toml"
+    assert ($config.name == "test")
+}
+
+def test_file_operations [] {
+    let temp_file = "temp-test.txt"
+    "test content" | save $temp_file
+    assert ($temp_file | path exists)
+    rm $temp_file
+}
+```
+
+---
+
+## Performance Considerations
+
+### Efficient Data Processing
+```nushell
+# ✅ Good: Use pipeline for streaming
+def process_large_file [] {
+    open --raw large.txt
+    | lines
+    | where {|line| $line | str contains "ERROR"}
+    | each {|line| parse_error_line $line}
+}
+
+# ❌ Avoid: Loading everything into memory
+def process_large_file_bad [] {
+    let all_lines = open large.txt | lines
+    let errors = $all_lines | where {|line| $line | str contains "ERROR"}
+    # Processes entire file at once
+}
+```
+
+### Lazy Evaluation
+```nushell
+# Take advantage of lazy evaluation
+def find_first_match [pattern: string] {
+    glob **/*.txt
+    | each { open }
+    | where {|content| $content | str contains $pattern}
+    | first  # Stops after first match
+}
+```
+
+### Avoid Unnecessary Conversions
+```nushell
+# ✅ Good: Work with structured data
+def get_names [] {
+    open users.json
+    | get users
+    | each {|user| $user.name}
+}
+
+# ❌ Avoid: Converting to strings unnecessarily
+def get_names_bad [] {
+    open users.json
+    | to text  # Unnecessary conversion
+    | from json
+    | get users
+}
+```
+
+---
+
+## Common Pitfalls
+
+### Pitfall 1: Closure vs Block Confusion
+```nushell
+# ❌ Wrong: Using $in in closure parameter context
+let bad = [1, 2, 3] | where { $in > 1 }  # May not work in newer versions
+
+# ✅ Correct: Use explicit parameter
+let good = [1, 2, 3] | where {|x| $x > 1}
+```
+
+### Pitfall 2: Mutable Variable Scope
+```nushell
+# ❌ Wrong: Trying to mutate outer scope
+def increment_bad [] {
+    let mut counter = 0
+    [1, 2, 3] | each {|x|
+        $counter = $counter + 1  # Error: can't mutate outer scope
+    }
+}
+
+# ✅ Correct: Use reduce or return values
+def increment_good [] -> int {
+    [1, 2, 3] | reduce {|acc, val| $acc + 1} --fold 0
+}
+```
+
+### Pitfall 3: Missing Error Handling
+```nushell
+# ❌ Risky: No error handling
+def load_config [] {
+    open config.toml | get database.url  # Crashes if missing
+}
+
+# ✅ Safe: Handle errors gracefully
+def load_config_safe [] -> string {
+    try {
+        open config.toml | get database.url
+    } catch {
+        print "Warning: Using default database URL"
+        "sqlite::memory:"
+    }
+}
+```
+
+### Pitfall 4: Type Mismatches
+```nushell
+# ❌ Wrong: Implicit type assumption
+def add [a, b] {  # No type annotations
+    $a + $b  # May fail if wrong types
+}
+
+# ✅ Correct: Explicit types
+def add [a: int, b: int] -> int {
+    $a + $b
+}
+```
+
+### Pitfall 5: Path Handling
+```nushell
+# ❌ Wrong: Hardcoded paths
+def get_config [] {
+    open /Users/username/config.toml  # Not portable
+}
+
+# ✅ Correct: Use environment variables and path expansion
+def get_config [] -> record {
+    let config_path = $"($env.HOME)/.config/syntaxis/config.toml"
+    if ($config_path | path exists) {
+        open $config_path
+    } else {
+        {}
+    }
+}
+```
+
+### Pitfall 6: Ignoring Null Values
+```nushell
+# ❌ Wrong: Assumes value exists
+def get_value [data: record] {
+    $data.key.nested.value  # Crashes if any key missing
+}
+
+# ✅ Correct: Safe navigation
+def get_value_safe [data: record] -> any {
+    $data | get -i key.nested.value | default null
+}
+```

+## Migration Checklist for Existing Scripts
+
+When updating scripts to Nushell 0.109+:
+
+- [ ] **CRITICAL:** Update return type syntax from `] -> type {` to `]: nothing -> type {`
+- [ ] Update closures to use explicit parameters `{|x| ...}` instead of `{ $in ... }`
+- [ ] Add type annotations to function parameters and return types
+- [ ] Replace deprecated commands (check Nushell changelog)
+- [ ] Add proper error handling with try-catch
+- [ ] Use `export def` for public functions
+- [ ] Add documentation comments
+- [ ] Update file operations to use proper path checking
+- [ ] Replace string-based path handling with path commands
+- [ ] Add tests for critical functions
+- [ ] Verify null handling with `-i` flag and `default`
+- [ ] Check external command calls use `^` prefix
+- [ ] Ensure ANSI color usage is consistent
+- [ ] Change `let mut` to `mut` for mutable variables
