-# Demon CLI Improvement Plan
-
-## Overview
-This document outlines the planned improvements to the demon CLI tool based on feedback and best practices.
-
-## Improvement Tasks
-
-### 1. Switch to `anyhow` for Error Handling
-**Priority**: High  
-**Status**: Pending
-
-**Goal**: Replace `Box<dyn std::error::Error>` with `anyhow::Result` throughout the codebase for better error handling.
-
-**Tasks**:
-- Replace all `Result<(), Box<dyn std::error::Error>>` with `anyhow::Result<()>`
-- Use `anyhow::Context` for better error context
-- Simplify error handling code
-- Update imports and error propagation
-
-**Benefits**:
-- Better error messages with context
-- Simpler error handling
-- More idiomatic Rust error handling
-
-### 2. Implement CLI Testing with `assert_cmd`
-**Priority**: High  
-**Status**: Pending
-
-**Goal**: Create comprehensive integration tests for all CLI commands using the `assert_cmd` crate.
-
-**Prerequisites**:
-- Research and document `assert_cmd` usage in CLAUDE.md
-- Add `assert_cmd` dependency
-- Create test infrastructure
-
-**Test Coverage Required**:
-- `demon run`: Process spawning, file creation, duplicate detection
-- `demon stop`: Process termination, timeout handling, cleanup
-- `demon tail`: File watching behavior (basic scenarios)
-- `demon cat`: File content display, flag handling
-- `demon list`: Process listing, status detection
-- `demon status`: Individual process status checks
-- `demon clean`: Orphaned file cleanup
-- Error scenarios: missing files, invalid PIDs, etc.
-
-**Test Structure**:
-```
-tests/
-├── cli.rs              # Main CLI integration tests
-├── fixtures/           # Test data and helper files
-└── common/             # Shared test utilities
-```
-
-### 3. Add Quiet Flag to List Command
-**Priority**: Medium  
-**Status**: Pending
-
-**Goal**: Add `-q/--quiet` flag to the `demon list` command for machine-readable output.
-
-**Requirements**:
-- Add `quiet` field to `ListArgs` struct (if needed, since `List` currently has no args)
-- Convert `List` command to use `ListArgs` struct
-- When quiet flag is used:
-  - No headers
-  - One line per process: `id:pid:status`
-  - No "No daemon processes found" message when empty
-
-**Example Output**:
-```bash
-# Normal mode
-$ demon list
-ID                   PID      STATUS     COMMAND
---------------------------------------------------
-my-app               12345    RUNNING    N/A
-
-# Quiet mode
-$ demon list -q
-my-app:12345:RUNNING
-```
-
-### 4. Add LLM Command
-**Priority**: Medium  
-**Status**: Pending
-
-**Goal**: Add a `demon llm` command that outputs a comprehensive usage guide for other LLMs.
-
-**Requirements**:
-- Add `Llm` variant to `Commands` enum
-- No arguments needed
-- Output to stdout (not stderr like other messages)
-- Include all commands with examples
-- Assume the reader is an LLM that needs to understand how to use the tool
-
-**Content Structure**:
-- Tool overview and purpose
-- All available commands with syntax
-- Practical examples for each command
-- Common workflows
-- File structure explanation
-- Error handling tips
-
-### 5. Remove `glob` Dependency
-**Priority**: Low  
-**Status**: Pending
-
-**Goal**: Replace the `glob` crate with standard library `std::fs` functionality.
-
-**Implementation**:
-- Remove `glob` from Cargo.toml
-- Replace `glob("*.pid")` with `std::fs::read_dir()` + filtering
-- Update imports
-- Ensure same functionality is maintained
-
-**Functions to Update**:
-- `list_daemons()`: Find all .pid files
-- `clean_orphaned_files()`: Find all .pid files
-
-**Implementation Pattern**:
-```rust
-// Replace glob("*.pid") with:
-std::fs::read_dir(".")?
-    .filter_map(|entry| entry.ok())
-    .filter(|entry| {
-        entry.path().extension()
-            .and_then(|ext| ext.to_str())
-            .map(|ext| ext == "pid")
-            .unwrap_or(false)
-    })
-```
-
-## Implementation Order
-
-1. **Document assert_cmd** - Add understanding to CLAUDE.md
-2. **Switch to anyhow** - Foundation for better error handling
-3. **Implement tests** - Ensure current functionality works correctly
-4. **Add quiet flag** - Small feature addition
-5. **Add LLM command** - Documentation feature
-6. **Remove glob** - Cleanup and reduce dependencies
-
-## Success Criteria
-
-- [ ] All existing functionality remains intact
-- [ ] Comprehensive test coverage (>80% of CLI scenarios)
-- [ ] Better error messages with context
-- [ ] Machine-readable list output option
-- [ ] LLM-friendly documentation command
-- [ ] Reduced dependency footprint
-- [ ] All changes committed with proper messages
-
-## Risk Assessment
-
-**Low Risk**:
-- anyhow migration (straightforward replacement)
-- quiet flag addition (additive change)
-- LLM command (new, isolated feature)
-
-**Medium Risk**:
-- glob removal (need to ensure exact same behavior)
-- CLI testing (need to handle file system interactions carefully)
-
-## Notes
-
-- Each improvement should be implemented, tested, and committed separately
-- Maintain backward compatibility for all existing commands
-- Update IMPLEMENTATION_PLAN.md as work progresses
-- Consider adding integration tests that verify the actual daemon functionality
