 RP is a sophisticated command-line AI assistant designed for autonomous task execution, advanced tool integration, and intelligent workflow management. Built with a focus on reliability, extensibility, and developer productivity.
 
 ## Overview
@@ -10,11 +12,44 @@ RP provides autonomous execution capabilities by default, enabling complex multi
 
 ### Core Capabilities
 - **Autonomous Execution**: Tasks run to completion by default with intelligent decision-making
+- **Multi-Language Support**: Automatic detection and analysis for Python, C, C++, Rust, Go, JavaScript, TypeScript, and Java
 - **Advanced Tool Integration**: Comprehensive tool set for filesystem operations, web interactions, code execution, and system management
 - **Real-time Cost Tracking**: Built-in usage monitoring and cost estimation for API calls
 - **Session Management**: Save, load, and manage conversation sessions with persistent state
 - **Plugin Architecture**: Extensible system for custom tools and integrations
 
+### Language-Agnostic Analysis
+
+RP automatically detects the programming language and provides tailored analysis:
+
+| Language | Features |
+|----------|----------|
+| Python | Dependency detection, version requirements, breaking change detection (pydantic v2, FastAPI) |
+| C/C++ | Header analysis, stdlib/POSIX/external library detection, compiler flag suggestions, Makefile generation |
+| Rust | Cargo.toml detection, crate analysis |
+| Go | go.mod detection, package analysis |
+| JavaScript/TypeScript | package.json detection, module analysis |
+| Java | Maven/Gradle detection, dependency analysis |
+
+### C/C++ Development Support
+
+Full support for C and C++ projects including:
+
+- **Header Classification**: Distinguishes between standard library, POSIX, local, and external library headers
+- **Compiler Flags**: Automatic suggestion of `-std=c99/c11/gnu99`, `-Wall`, `-Wextra`, `-pthread`, `-lm`, etc.
+- **Library Detection**: Maps headers to system packages (curl, openssl, sqlite3, zlib, ncurses, etc.)
+- **Package Manager Integration**: Install commands for Debian/Ubuntu, Fedora, Arch, and Homebrew
+- **Build System Detection**: Identifies Makefile, CMake, Meson, and Autotools projects
+- **Makefile Generation**: Creates complete Makefiles with proper LDFLAGS and dependencies
+
+Example: For code with `#include <curl/curl.h>`:
+```
+Language: c
+Dependency: curl/curl.h → curl
+Install: apt-get install -y libcurl4-openssl-dev
+Linker: -lcurl
+```

+                              Quick Reference Guide
+================================================================================
+
+OVERVIEW
+--------
+This document describes all keyboard shortcuts available during build
+operations in the rp AI assistant. These shortcuts allow you to control
+build execution, monitor costs, and customize output in real-time.
+
+================================================================================
+VISUAL CONTROL SHORTCUTS
+================================================================================
+
+Ctrl+K  -  Clear Current Step Output
+         Clears the terminal display to remove clutter from previous steps.
+         Use when output becomes too long and you want a fresh view.
+         Works in any build phase.
+
+Ctrl+L  -  Toggle Live Cost Ticker
+         Shows or hides the real-time cost tracking panel that displays:
+         - Current build cost
+         - Session cost
+         - Budget remaining
+         - Burn rate (cost per second)
+         Default: Enabled
+
+Ctrl+H  -  Show Build History
+         Displays the last 5 completed steps with their:
+         - Success/failure status

+         - Duration
+         Useful for reviewing what has been accomplished.
+
+Ctrl+I  -  Toggle Token Breakdown
+         When enabled, the cost panel shows detailed token counts:
+         - Input tokens and their cost
+         - Output tokens and their cost
+         Helps understand where costs are coming from.
+
+================================================================================
+EXECUTION CONTROL SHORTCUTS
+================================================================================
+
+Ctrl+Shift+P  -  Pause/Resume Execution
+               Temporarily pauses the current build without canceling.

+               Press again to resume from where you left off.
+
+Ctrl+D  -  Dry-Run Mode Toggle
+         When enabled, shows cost estimates without executing.
+         Useful for:
+         - Planning complex builds
+         - Estimating costs before committing
+         - Testing build configurations
+         No API calls made in dry-run mode.
+
+Ctrl+R  -  Retry Last Failed Step
+         Re-executes the most recent step that failed.
+         Only available when a step has failed.
+         Does not affect previous successful steps.
+
+Ctrl+E  -  Export Session Logs
+         Saves all build logs to a timestamped JSON file.

+================================================================================
+COST TRACKING SYSTEM
+================================================================================
+
+HOW COSTS ARE CALCULATED
+------------------------
+Costs are tracked in EUR (Euro) using the following formula:
+
+  Input Cost  = Input Tokens  x (0.20 EUR / 1,000,000 tokens)
+  Output Cost = Output Tokens x (1.50 EUR / 1,000,000 tokens)
+  Total Cost  = Input Cost + Output Cost
+
+Token counts are provided by the API response and represent:
+- Input Tokens: Your prompts, context, and system messages
+- Output Tokens: AI-generated responses and tool outputs
+
+COST DISPLAY FORMAT
+-------------------
+All costs shown to 4 decimal places for accuracy:
+  Cost this step: EUR0.0023 (1,234 input + 567 output tokens)
+
+COST PANEL COMPONENTS
+---------------------
+  This Build:  Total cost since build started
+  Session:     Total cost since rp started
+  Budget:      Configurable spending limit
+  Remaining:   Budget minus session cost
+  Burn Rate:   Cost per second (averaged over build)
+
+================================================================================
+EXAMPLE BUILD WITH COSTS
+================================================================================
+
+Below is an example build showing typical cost output:
+
+  STEP [1/5]: Initialize Project
+  ----------
+  -> Scanning project directory
+  -> Loading configuration
+  [████████████████░░░░░░░░░░░░░░] 55%
+  Cost this step: EUR0.0012 (800 input + 200 output tokens)
+
+  STEP [2/5]: Analyze Dependencies
+  ----------
+  -> Parsing package.json
+  -> Resolving versions
+  [██████████████████████████████] 100%
+  Cost this step: EUR0.0018 (1,100 input + 350 output tokens)
+
+  ...
+
+  BUILD COMPLETED SUCCESSFULLY
+
+  Summary:
+    Total steps:    5
+    Duration:       45.2s
+
+  Step-by-step cost breakdown:
+    1. Initialize Project: EUR0.0012
+    2. Analyze Dependencies: EUR0.0018
+    3. Generate Code: EUR0.0089
+    4. Run Tests: EUR0.0034
+    5. Package Output: EUR0.0015
+
+  Token breakdown:
+    Input tokens:   12,450
+    Output tokens:   3,280
+    Total tokens:   15,730
+
+  Total cost: EUR0.0168
+  Average cost per step: EUR0.0034
+  Output artifacts: 3
+
+================================================================================
+TERMINAL COMPATIBILITY
+================================================================================
+
+SUPPORTED TERMINALS
+-------------------
+The following terminals are fully supported:
+- Linux: gnome-terminal, konsole, xterm, alacritty, kitty
+- macOS: Terminal.app, iTerm2, Alacritty
+- Windows: Windows Terminal, ConEmu, Cmder
+
+TTY DETECTION
+-------------
+Features automatically disable when output is piped:
+- Colors and formatting removed
+- Progress bars show plain text
+- Cost panels simplified
+Non-TTY mode activates when: os.isatty(sys.stdout.fileno()) = False
+
+READLINE REQUIREMENTS
+---------------------
+Full keybinding support requires GNU readline:
+- Linux: Usually pre-installed (libreadline)
+- macOS: Install via brew: brew install readline
+- Windows: pyreadline3 package (pip install pyreadline3)
+
+If readline is unavailable:
+- Basic operation continues
+- Keybindings show as disabled
+- Manual commands still work
+
+================================================================================
+TROUBLESHOOTING
+================================================================================
+
+KEYBINDINGS NOT WORKING
+-----------------------
+1. Check readline is installed:
+   python -c "import readline; print('OK')"
+
+2. Check terminal type:
+   echo $TERM
+   (Should be xterm-256color or similar)
+
+3. Some terminals intercept keys:
+   - Ctrl+S may be captured for terminal suspend
+   - Alt keys may conflict with menu shortcuts
+   Try different terminal emulator.
+
+COST PANEL NOT DISPLAYING
+-------------------------
+1. Ensure TTY mode:
+   - Run directly in terminal, not piped
+   - Check: python -c "import os,sys; print(os.isatty(sys.stdout.fileno()))"
+
+2. Toggle with Ctrl+L to re-enable
+
+3. Check verbosity level (Alt+V to increase)
+
+EXPORT FAILING
+--------------
+1. Check permissions on: ~/.local/share/rp/logs/
+2. Ensure disk space available
+3. Try manual directory creation:
+   mkdir -p ~/.local/share/rp/logs
+
+COLORS NOT SHOWING
+------------------
+1. Check TERM environment:
+   export TERM=xterm-256color
+
+2. Check terminal color support:
+   tput colors (should return 256 or higher)
+
+3. Try --no-syntax flag if issues persist
