## [Unreleased]

### Added

#### Enhancement Workflow Preset Management (`skill-seekers workflows`)
- New `workflows` CLI subcommand to manage enhancement workflow presets
- Bundled presets shipped as YAML files inside the package (`skill_seekers/workflows/`)
  - `default`, `minimal`, `security-focus`, `architecture-comprehensive`, `api-documentation`
- User presets stored in `~/.config/skill-seekers/workflows/`
- Subcommands:
  - `skill-seekers workflows list` — List all bundled + user workflows with descriptions
  - `skill-seekers workflows show <name>` — Print YAML content of a workflow
  - `skill-seekers workflows copy <name> [name ...]` — Copy bundled workflow(s) to user dir
  - `skill-seekers workflows add <file.yaml> [file ...]` — Install custom YAML file(s) into user dir
  - `skill-seekers workflows remove <name> [name ...]` — Delete user workflow(s)
  - `skill-seekers workflows validate <name|path>` — Parse and validate a workflow
- `copy`, `add`, `remove` all accept multiple names/files in one command (partial-failure: continues processing, returns non-zero exit if any item fails)
- `add --name` flag override is restricted to single-file operations
- New entry point: `skill-seekers-workflows`

#### Multiple `--enhance-workflow` flags from CLI
- `skill-seekers create <source> --enhance-workflow security-focus --enhance-workflow minimal` — apply multiple workflows in a single command
- All workflow management commands (`copy`, `add`, `remove`) now accept multiple names/files in one invocation

### Fixed
- `create` command `_add_common_args()` now correctly forwards each workflow as a separate `--enhance-workflow` flag to sub-scrapers (previously passed the whole list as a single argument, causing all workflows to be ignored)

### Changed
- `workflows copy` now accepts one or more workflow names: `skill-seekers workflows copy wf-a wf-b`
- `workflows add` now accepts one or more YAML files: `skill-seekers workflows add a.yaml b.yaml`
- `workflows remove` now accepts one or more workflow names: `skill-seekers workflows remove wf-a wf-b`

### Fixed

#### URL Conversion Bug with Anchor Fragments (Issue #277)
- **Critical Bug Fix**: Fixed 404 errors when scraping documentation with anchor links
  - **Problem**: URLs with anchor fragments (e.g., `#synchronous-initialization`) were malformed
    - Incorrect: `https://example.com/docs/api#method/index.html.md` ❌
    - Correct: `https://example.com/docs/api/index.html.md` ✅
  - **Root Cause**: `_convert_to_md_urls()` didn't strip anchor fragments before appending `/index.html.md`
  - **Solution**: Parse URLs with `urllib.parse` to remove fragments and deduplicate base URLs
  - **Impact**: Prevents duplicate requests for the same page with different anchors
  - **Additional Fix**: Changed `.md` detection from `".md" in url` to `url.endswith('.md')`
    - Prevents false matches on URLs like `/cmd-line` or `/AMD-processors`
- **Test Coverage**: 12 comprehensive tests covering all edge cases
  - Anchor fragment stripping
  - Deduplication of multiple anchors on same URL
  - Query parameter preservation
  - Trailing slash handling
  - Real-world MikroORM case validation
  - 54/54 tests passing (42 existing + 12 new)
- **Reported by**: @devjones via Issue #277

  - **Comprehensive test coverage**: 7 new tests, 30/30 passing (100%)
  - **False positive prevention**: Unique identifiers (weight 5) + confidence thresholds
  - **No regressions**: All existing language detection tests still pass
  - **Total language support**: Now 27+ programming languages
  - **Credit**: Contributed by @PaawanBarach via PR #275

  - No need for separate `skill-seekers enhance` command
  - Seamless one-command workflow
  - 10-minute timeout for large codebases
  - Graceful fallback with retry instructions on failure
- **LOCAL Mode Fallback**: All AI enhancements now fall back to LOCAL mode when no API key is set
  - Applies to: pattern enhancement (C3.1), test examples (C3.2), architecture (C3.7)
  - Uses Claude Code CLI instead of failing silently
  - Better UX: "Using LOCAL mode (Claude Code CLI)" instead of "AI disabled"

- Support for custom Claude-compatible API endpoints via `ANTHROPIC_BASE_URL` environment variable
- Compatibility with GLM-4.7 and other Claude-compatible APIs across all AI enhancement features

### Changed

#### Godot Game Engine Fixes
- **GDScript Dependency Extraction**: Fixed 265+ "Syntax error in *.gd" warnings (commit 3e6c448)
  - GDScript files were incorrectly routed to Python AST parser
  - Created dedicated `_extract_gdscript_imports()` with regex patterns
  - Now correctly parses `preload()`, `load()`, `extends` patterns
  - Result: 377 dependencies extracted with 0 warnings

- **Framework Detection False Positive**: Fixed Unity detection on Godot projects (commit 50b28fe)
  - Was detecting "Unity" due to generic "Assets" keyword in comments
  - Changed Unity markers to specific files: `Assembly-CSharp.csproj`, `UnityEngine.dll`, `Library/`
  - Now correctly detects Godot via `project.godot`, `.godot` directory

- **Circular Dependencies**: Fixed self-referential cycles (commit 50b28fe)
  - 3 self-loop warnings (files depending on themselves)
  - Added `target != file_path` check in dependency graph builder
  - Result: 0 circular dependencies detected

- **GDScript Test Discovery**: Fixed 0 test files found in Godot projects (commit 50b28fe)
  - Added GDScript test patterns: `test_*.gd`, `*_test.gd`
  - Added GDScript to LANGUAGE_MAP

  - Result: 22 test examples extracted successfully

- **Config Extractor Array Handling**: Fixed JSON/YAML array parsing (commit fca0951)
  - Error: `'list' object has no attribute 'items'` on root-level arrays
  - Added isinstance checks for dict/list/primitive at root
  - Result: No JSON array errors, save.json parsed correctly

- **Progress Indicators**: Fixed missing progress for small batches (commit eec37f5)
  - Progress only shown every 5 batches, invisible for small jobs
  - Modified condition to always show for batches < 10
  - Result: "Progress: 1/2 batches completed" now visible

#### Other Fixes
- **C# Test Extraction**: Fixed "Language C# not supported" error with language alias mapping
- **Config Type Field Mismatch**: Fixed KeyError in `config_enhancer.py` by supporting both "type" and "config_type" fields
- **LocalSkillEnhancer Import**: Fixed incorrect import and method call in `main.py` (SkillEnhancer → LocalSkillEnhancer)

## [2.7.4] - 2026-01-22

### 🔧 Bug Fix - Language Selector Links

This **patch release** fixes the broken Chinese language selector link that appeared on PyPI and other non-GitHub platforms.

### Fixed

- **Broken Language Selector Links on PyPI**
  - **Issue**: Chinese language link used relative URL (`README.zh-CN.md`) which only worked on GitHub
  - **Impact**: Users on PyPI clicking "简体中文" got 404 errors
  - **Solution**: Changed to absolute GitHub URL (`https://github.com/yusufkaraaslan/Skill_Seekers/blob/main/README.zh-CN.md`)
  - **Result**: Language selector now works on PyPI, GitHub, and all platforms
  - **Files Fixed**: `README.md`, `README.zh-CN.md`

### Technical Details

**Why This Happened:**
- PyPI displays `README.md` but doesn't include `README.zh-CN.md` in the package
- Relative links break when README is rendered outside GitHub repository context
- Absolute GitHub URLs work universally across all platforms

**Impact:**
- ✅ Chinese language link now accessible from PyPI
- ✅ Consistent experience across all platforms
- ✅ Better user experience for Chinese developers

---

## [2.7.3] - 2026-01-21

## [2.7.2] - 2026-01-21

### 🚨 Critical CLI Bug Fixes

This **hotfix release** resolves 4 critical CLI bugs reported in issues #258 and #259 that prevented core commands from working correctly.

### Fixed

- **Issue #258: `install --config` command fails with unified scraper** (#258)
  - **Root Cause**: `unified_scraper.py` missing `--fresh` and `--dry-run` argument definitions
  - **Solution**: Added both flags to unified_scraper argument parser and main.py dispatcher
  - **Impact**: `skill-seekers install --config react` now works without "unrecognized arguments" error
  - **Files Fixed**: `src/skill_seekers/cli/unified_scraper.py`, `src/skill_seekers/cli/main.py`

- **Issue #259 (Original): `scrape` command doesn't accept URL and --max-pages** (#259)
  - **Root Cause**: No positional URL argument or `--max-pages` flag support
  - **Solution**: Added positional URL argument and `--max-pages` flag with safety warnings
  - **Impact**: `skill-seekers scrape https://example.com --max-pages 50` now works
  - **Safety Warnings**:
    - ⚠️ Warning if max-pages > 1000 (may take hours)
    - ⚠️ Warning if max-pages < 10 (incomplete skill)
  - **Files Fixed**: `src/skill_seekers/cli/doc_scraper.py`, `src/skill_seekers/cli/main.py`

- **Issue #259 (Comment A): Version shows 2.7.0 instead of actual version** (#259)
  - **Root Cause**: Hardcoded version string in main.py
  - **Solution**: Import `__version__` from `__init__.py` dynamically
  - **Impact**: `skill-seekers --version` now shows correct version (2.7.2)
  - **Files Fixed**: `src/skill_seekers/cli/main.py`

- **Issue #259 (Comment B): PDF command shows empty "Error: " message** (#259)
  - **Root Cause**: Exception handler didn't handle empty exception messages
  - **Solution**:
    - Improved exception handler to show exception type if message is empty
    - Added proper error handling with context-specific messages
    - Added traceback support in verbose mode
  - **Impact**: PDF errors now show clear messages like "Error: RuntimeError occurred" instead of just "Error: "
  - **Files Fixed**: `src/skill_seekers/cli/main.py`, `src/skill_seekers/cli/pdf_scraper.py`

### Testing

- ✅ Verified `skill-seekers install --config react --dry-run` works
- ✅ Verified `skill-seekers scrape https://tailwindcss.com/docs/installation --max-pages 50` works
- ✅ Verified `skill-seekers --version` shows "2.7.2"
- ✅ Verified PDF errors show proper messages
- ✅ All 202 tests passing

---

## [2.7.1] - 2026-01-18

### 🚨 Critical Bug Fix - Config Download 404 Errors

This **hotfix release** resolves a critical bug causing 404 errors when downloading configs from the API.

### Fixed

- **Critical: Config download 404 errors** - Fixed bug where code was constructing download URLs manually instead of using the `download_url` field from the API response
  - **Root Cause**: Code was building `f"{API_BASE_URL}/api/download/{config_name}.json"` which failed when actual URLs differed (CDN URLs, version-specific paths)
  - **Solution**: Changed to use `config_info.get("download_url")` from API response in both MCP server implementations
  - **Files Fixed**:
    - `src/skill_seekers/mcp/tools/source_tools.py` (FastMCP server)
    - `src/skill_seekers/mcp/server_legacy.py` (Legacy server)
  - **Impact**: Fixes all config downloads from skillseekersweb.com API and private Git repositories
  - **Reported By**: User testing `skill-seekers install --config godot --unlimited`
  - **Testing**: All 15 source tools tests pass, all 8 fetch_config tests pass

  - **Old flags (DEPRECATED)**: `--build-api-reference`, `--build-dependency-graph`, `--detect-patterns`, `--extract-test-examples`
  - **New flags**: `--skip-api-reference`, `--skip-dependency-graph`, `--skip-patterns`, `--skip-test-examples`
  - **Migration**: Remove old `--build-*` flags from your scripts (features are now ON by default)
  - **Backward compatibility**: Deprecated flags show warnings but still work (will be removed in v3.0.0)
  - **Rationale**: Users should get maximum value by default; explicitly opt-out if needed
  - **Impact**: `codebase-scraper --directory .` now runs all analysis features automatically

### Fixed
- **Codebase Scraper Language Stats** - Fixed dict format handling in `_get_language_stats()`
  - **Issue**: `AttributeError: 'dict' object has no attribute 'suffix'` when generating SKILL.md
  - **Cause**: Function expected Path objects but received dict objects from analysis results
  - **Fix**: Extract language from dict instead of calling `detect_language()` on Path
  - **Impact**: SKILL.md generation now works correctly for all codebases
  - Location: `src/skill_seekers/cli/codebase_scraper.py:778`

```bash
# IT pre-configures sources
add_config_source(name="platform", ..., priority=1)
add_config_source(name="mobile", ..., priority=2)

# Developers use transparently
fetch_config(config_name="platform-api")  # Finds in platform source
```

- Added (6): 3 source files + 3 test files + 1 doc + 1 example repo
- Total lines added: ~2,600

### Migration Guide

No migration needed! This is purely additive:

```python
# Before v2.2.0 (still works)
fetch_config(config_name="react")

# New in v2.2.0 (optional)
add_config_source(name="team", git_url="...")
fetch_config(source="team", config_name="react-custom")
```
