Resolves issue where users on corporate/managed machines cannot write to ~/.mlx directory.

Key Features:
- Automatically detects first writable location from prioritized paths
- Tests write permissions before selecting a directory
- Creates directories automatically if they don't exist
- Falls back to ~/Documents/MLXCode/models for work machines
- Backward compatible with existing ~/.mlx/models setups
- Dynamic UI updates showing user's configured path

Changes:
- AppSettings.swift: Added detectWritableModelsPath() with automatic detection
- MLXModel.swift: Models now use dynamic base paths
- MLXService.swift: Expanded model search to all possible locations
- PathsSettingsView.swift: Reset uses smart detection
- PrerequisitesView.swift: Documentation reflects user's actual path
- .gitignore: Fixed to allow MLX Code/Models/ source directory

Tested on:
- Fresh installs with no existing directories
- Restricted environments (simulated corporate policies)
- Existing setups with populated ~/.mlx/models
- Multiple model storage locations
- Manual path overrides

- Added Smart Path Detection feature documentation
- Included v3.3.0 context-aware analysis entry
- Updated last modified date to 2025-12-09
This release fixes multiple critical bugs preventing model loading on sandboxed systems.

CRITICAL BUG FIXES:

1. JSON Decoding Error - "The data couldn't be read because it is missing"
   - Root cause: PythonResponse.type was non-optional but daemon's load response omits it
   - Fix: Made type field optional (type: String?)
   - Impact: JSONDecoder can now parse all daemon responses
   - Files: MLXService.swift:741

2. Token Accumulation Bug - Generation stopped at 11 tokens
   - Root cause: "complete" signal overwrote accumulated tokens with empty string
   - Fix: Preserve fullResponse instead of resetting to response.text
   - Impact: Full generation responses now returned
   - Files: MLXService.swift:274-276

3. xcrun Sandbox Error - "xcrun: error: cannot be used within an App Sandbox"
   - Root cause 1: /usr/bin/python3 is xcode-select shim that calls xcrun
   - Root cause 2: mlx_lm.convert import triggers compilation requiring xcrun
   - Root cause 3: Xcode paths in PATH environment variable
   - Fix 1: Use direct Python binary path (python3.9)
   - Fix 2: Disabled mlx_lm.convert entirely (mlx-community models don't need conversion)
   - Fix 3: Set PYTHONPATH for user packages
   - Fix 4: Removed app sandbox (incompatible with dev tool requirements)
   - Files: MLXService.swift:424, 829, 454-462; huggingface_downloader.py:26-28

4. Missing Python Packages - "huggingface_hub not installed"
   - Root cause: Python subprocess couldn't find user site-packages
   - Fix: Added PYTHONPATH=/Users/*/Library/Python/3.9/lib/python/site-packages
   - Impact: All user-installed packages now accessible
   - Files: MLXService.swift:438, 457

NEW FEATURES:

1. Model Auto-Discovery on Startup
   - Scans configured models directory for actual models
   - Updates model list with real filesystem paths
   - Auto-selects first discovered model
   - Files: MLXCodeApp.swift:39-63

2. Manual "Scan Disk" Button
   - Added to Settings → Model tab
   - Finds all models across multiple locations
   - Shows popup with discovered models and paths
   - Files: SettingsView.swift:247-266, 635-684

3. Setup Script for External Model Downloads
   - Standalone bash script to download models outside app
   - Bypasses all sandbox/permission issues
   - Interactive menu for model selection
   - Files: setup_mlx_models.sh (new)

4. Comprehensive Unit Tests
   - Tests JSON response decoding
   - Tests model path validation
   - Tests filesystem access
   - Tests daemon communication
   - Files: MLX Code Tests/MLXServiceTests.swift (new)

5. Enhanced Debug Logging
   - Added debug message type to daemon
   - Logs raw JSON before parsing
   - Logs expanded paths and file checks
   - Shows exact errors with context
   - Files: mlx_daemon.py:51-66, 86-97; MLXService.swift:617-639

TECHNICAL CHANGES:

- Removed App Sandbox (MLX_Code.entitlements)
  - Dev tool needs full filesystem access for Xcode projects
  - Needs to run Python subprocesses with model file access
  - Kept network.client and automation.apple-events

- Direct Python Binary Path
  - Changed from: /usr/bin/python3 (xcode-select shim)
  - Changed to: /Applications/Xcode.app/.../python3.9 (direct binary)
  - Prevents xcrun calls in subprocess

- Clean Environment Variables
  - PATH: Minimal safe paths, no Xcode directories
  - PYTHONPATH: User site-packages for mlx/huggingface-hub
  - HOME: For cache directories
  - TMPDIR: For temporary files
  - Removed: DEVELOPER_DIR, XCODE_VERSION_ACTUAL, DT_TOOLCHAIN_DIR

- Expanded PythonResponse Struct
  - Added: path, name, stage, skipped, repo_id, size_bytes, size_gb, quantization, converted_to_mlx
  - All fields optional for maximum flexibility

TESTING:

Unit tests verify:
✅ JSON decoding with/without type field
✅ Model path validation and expansion
✅ Filesystem access to model directories
✅ Daemon response parsing

Manual testing verified:
✅ Model discovery finds 6 models across 2 locations
✅ Python daemon loads models successfully
✅ Direct Python calls work with PYTHONPATH
✅ huggingface_downloader works with clean environment

KNOWN ISSUES RESOLVED:

- "The data couldn't be read because it is missing" → Fixed (optional type field)
- "xcrun: error: cannot be used within an App Sandbox" → Fixed (direct Python + no sandbox)
- "huggingface_hub not installed" → Fixed (PYTHONPATH)
- "Failed to load model" → Fixed (model auto-discovery)
- "Stuck at 11 tokens" → Fixed (preserve accumulated tokens)

Critical fix: Makes GitHub integration actually usable by the LLM!

## What This Adds
- GitHubTool.swift: New tool that exposes GitHub operations to the LLM
- Registered in ToolRegistry so LLM can discover and use it
- Updated system prompts to inform LLM about GitHub capabilities

## How It Works
When user asks MLX Code about GitHub (e.g., "list my repositories", "create an issue"),
the LLM can now:
1. Detect it's a GitHub request
2. Use the `github` tool with appropriate operation
3. Return GitHub data directly in the chat

## Supported Operations
- list_repos: List user's repositories
- get_repo: Get repository details
- create_repo: Create new repository
- list_issues: List issues in repository
- create_issue: Create new issue
- get_issue: Get issue details
- comment_issue: Comment on an issue
- list_prs: List pull requests
- get_pr: Get PR details
- create_pr: Create pull request
- list_releases: List releases
- create_release: Create new release
- list_gists: List gists
- create_gist: Create new gist
- list_workflows: List GitHub Actions workflows
- list_workflow_runs: List workflow run history
- search_repos: Search GitHub repositories
- search_issues: Search issues
- get_user: Get current user info

## Example Usage
User: "What repositories do I have?"
LLM: Uses github(operation=list_repos) → Returns formatted list

User: "Create an issue about the bug we just found"
LLM: Uses github(operation=create_issue, title=..., body=...) → Creates issue

## Security
- Uses configured GitHub token from Keychain
- Validates GitHub is configured before executing
- All API calls go through secure GitHubService
- Proper error handling and user feedback

Critical UX improvement: LLM no longer exposes tool implementation details.

## Problem
When users asked "list my repos", MLX Code responded with:
"Listing your repositories. [After using github tool] Here are your repositories..."

This exposed implementation details and made responses clunky.

## Solution
Updated SystemPrompts.swift with explicit rules:

### What Changed
- Added "CRITICAL RULES" section with clear ❌ and ✅ examples
- Explicitly forbids mentioning tool names or tool usage
- Provides good/bad example comparisons
- Emphasizes tools are implementation details

### New Rules
❌ NEVER say:
- "I'll use the github tool"
- "[After using X tool]"
- "Let me use the file_operations tool"

✅ ALWAYS say:
- "Let me check your repositories"
- "Here are your repositories:"
- "I'll read that file"

### Result
User: "List my repos"
Before: "Listing your repositories. [After using github tool] Here are..."
After: "You have 12 repositories: [clean list]"

Much cleaner UX that feels natural and hides implementation details.

Critical fix: LLM was copying example responses verbatim and returning fake data.

## Problem Identified
User asked "list my repos" and got back example text with fake repository names:
"You have 12 repositories: ### MLXCode ... ### HomeKitTV ..."

The LLM was treating example responses as templates to copy rather than patterns to follow.

## Solution
Completely restructured system prompts to:

1. **Remove detailed example responses** - These were being copied verbatim
2. **Add explicit anti-copying rules**:
   - "DO NOT copy example text"
   - "USE THE REAL DATA"
   - "Examples are PATTERNS to understand, NOT text to copy"

3. **Simplify tool transparency rules**:
   - Removed example conversations that could be copied
   - Focused on directive rules only
   - Emphasized presenting ACTUAL tool results

4. **Add data authenticity section**:
   - "Always present REAL data from tool results"
   - "Never make up or copy example data"
   - "Never use placeholder names, example numbers, or template text"

## Technical Changes
- Removed multi-line example conversations
- Replaced with short directive statements
- Added "Data Authenticity" section
- Strengthened "Tool Transparency Rule"
- Made instructions more explicit and less example-heavy

## Expected Behavior After Fix
User: "List my repos"
Before: "You have 12 repositories: ### MLXCode (fake example data)"
After: "You have 5 repositories: ### my-actual-repo (real data from GitHub API)"

CRITICAL: LLM was copying entire prompt instructions back to users.

Reduced baseSystemPrompt from 50+ lines to 12 lines.
Removed all example conversations that could be copied.
Simplified tool format instructions.

Result: Clean, minimal prompt that guides behavior without providing copyable text.
ROOT CAUSE: generateToolExamples() was producing detailed examples that LLM copied.

Solution: Return empty string from generateToolExamples().

No examples = nothing to copy = clean responses with real data.
Removed all references to Claude Code as co-author/contributor to address
copyright concerns. All work attributed solely to Jordan Koch.

Changes:
- Updated 8 documentation files
- Removed co-author attributions from implementation summaries

dependabot bot commented on behalf of github Feb 27, 2026

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
