and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).

## [3.6.0] - 2026-05-03

**Theme:** Quality-of-life release — packaging targets, GitHub issue workflow, codebase analysis fixes, and source detection hardening.

### Added
- **IBM Bob packaging target** — new `--target bob` adaptor and agent install support for IBM's Bob agent platform (#366)
- **GitHub issue filtering** — `--github-issue-state`, `--github-issue-labels`, and `--github-issue-since` filters in the GitHub scraper for narrowing which issues are pulled (#367)
- **Per-issue files** — GitHub scraper now writes one Markdown file per issue instead of a single bundle, improving navigation and downstream chunking (#367)
- **Pinecone frontmatter** — Pinecone vector exports now include consistent YAML frontmatter for metadata round-tripping (#367)

### Fixed
- **Unified scraper now generates `codebase_analysis/` index** — local sources were producing C3.x outputs with broken SKILL.md links; the unified skill builder now wires up the index and resolves links correctly (#362, #376)
- **Guides fallback fires correctly** — `unified_skill_builder` was emitting a truthy placeholder for empty guides which suppressed the fallback content; placeholder removed (#364, #375)
- **HTML URLs no longer treated as local files** — `source_detector` now checks for `http(s)://` before falling through to the local-path branch, fixing false-positive routing (#373)
- **PDF extracted images appear in markdown** — `pdf_scraper` now inserts `![](…)` references for images extracted from PDFs so they render in the generated SKILL.md (#369)
- **C3.x output for local sources** — `unified` command was skipping the C3.x analysis pipeline for local codebase sources; now emits the full pattern/test/guide/config/router output (#363, #372)
- **Language filter passed to C3.x clone analysis** — repos cloned for analysis now respect `--languages` instead of analyzing every file (fixes #361, #370)
- **Unity vs Unreal detection** — Unity projects with C# imports were being misidentified as Unreal; detection now keys on C# import patterns (fixes #365, #368)

## [3.5.1] - 2026-04-12

### Added
- **Centralized `defaults.json` config** — single source of truth for all default values (`rate_limit`, `max_pages`, `workers`, `async_mode`, enhancement, analysis, RAG settings). New `defaults.py` loader module. All 15+ files that previously hardcoded defaults now read from this file (#356)
- **Low-signal code snippet filtering** — `_is_low_signal_code_snippet()` filters junk patterns like bare `True`, `options`, single identifiers from quick references (#360)
- **Pattern description normalization** — `_normalize_pattern_description()` cleans boilerplate prefixes and truncates to first meaningful sentence (#360)
- **Example language priority ranking** — `_example_language_priority()` ranks Python > Bash > JSON > etc. for SKILL.md examples (#360)
- **`checkpoint_exists()` method** on `DocToSkillConverter` — was called but never defined (#360)
- **Unified config source normalization** — `DocToSkillConverter.__init__` merges fields from `sources[0]` into flat config for compatibility (#360)
- **`display_name` support** in SKILL.md generation — produces cleaner titles and slugs (#360)
- **New tests**: `test_doc_scraper_entrypoint.py` (regression for `_run_scraping`), quick-reference quality tests, docs-only compatibility tests, nested reference coverage tests (#360)

### Changed
- **`max_pages` default is now unlimited (`-1`)** — the scraper fetches all pages unless the user explicitly sets `--max-pages`. Previously defaulted to 500 (#356)
- **`--no-rate-limit` flag now works** — was defined in CLI arguments but never consumed by `ExecutionContext` (#356)
- **`constants.py` reads from `defaults.json`** — no longer contains hardcoded magic numbers (#356)
- **`ExecutionContext.ScrapingSettings`** — `rate_limit` and `max_pages` now use real defaults instead of `None`, preventing None-poisoning downstream (#356)
- **SKILL.md frontmatter cleanup** — empty `doc_version:` and `version:` fields are now omitted; placeholder sections removed (#360)
- **Enhancement routing through platform adaptors** instead of importing nonexistent `enhance_skill_md` helper (#360)
- **`quality_metrics.py` uses `rglob`** for nested reference directories in unified skills (#360)

### Fixed
- **`TypeError: '>' not supported between instances of 'NoneType' and 'int'`** — `rate_limit` defaulted to `None` in `ExecutionContext`, which flowed through `config.get("rate_limit", DEFAULT)` (dict.get returns None when the key exists with value None, ignoring the fallback). Fixed in `doc_scraper.py` (sync + async paths), `estimate_pages.py`, and `sync_config.py` (#356, #359)
- **`discover_urls()` loop never executed with unlimited `max_pages`** — `len(discovered) < -1` is always False. Added unlimited mode guard (#356)
- **`converter.scrape()` called nonexistent method** in `_run_scraping()` — changed to `converter.scrape_all()` (#360)
- **None-safety for BeautifulSoup attributes** — `link["href"]`, `sitemap.text`, `meta_desc["content"]` guarded against None XML text nodes (#360)
- **Python 3.10 compatibility** — backslash in f-string in `quality_metrics.py` not supported before 3.12 (#360)

## [3.5.0] - 2026-04-09

**Theme:** Grand Unification — one command, one interface, direct converters. Agent-agnostic architecture, marketplace pipeline, smart SPA discovery, all content extraction enabled by default. 80+ files changed across the codebase.

### Added
- **Grand Unification** — unified `create` command as single entry point for all 18 source types with auto-detection, direct converter invocation, and centralized enhancement (#346)
- **Agent-agnostic `AgentClient` abstraction** — all 5 enhancers now support Claude, Kimi, Codex, Copilot, OpenCode, and custom agents via a unified interface. Auto-detects agent from API keys instead of hardcoding (#336)
- **Kimi CLI integration** with stdin piping and output parsing (#336)
- **`MarketplacePublisher`** — publish skills to Claude Code plugin marketplace repos (#336)
- **`MarketplaceManager`** — register and manage marketplace repositories (#336)
- **`ConfigPublisher`** — push configs to registered config source repos (#336)
- **`push_config` MCP tool** for automated config publishing (#336)
- **Smart SPA discovery engine** — three-layer discovery: sitemap.xml, llms.txt, SPA nav rendering (#336)
- **`"browser": true` config support** for JavaScript SPA sites with browser renderer timeout defaults (60s, domcontentloaded) (#336)
- **Dynamic routing via `_build_argv()`** — replaced manual arg forwarding with dynamic forwarder, added 7 missing CLI flags (#336)
- **Kotlin language support for codebase analysis** — Full C3.x pipeline support: AST parsing (classes, objects, functions, data/sealed classes, extension functions, coroutines), dependency extraction, design pattern recognition (object declaration→Singleton, companion object→Factory, sealed class→Strategy), test example extraction (JUnit, Kotest, MockK, Spek), language detection patterns, config detection (build.gradle.kts), and extension maps across all analyzers (#287)
- **Headless browser rendering** (`--browser` flag) — uses Playwright to render JavaScript SPA sites (React, Vue, etc.) that return empty HTML shells. Auto-installs Chromium on first use. Optional dep: `pip install "skill-seekers[browser]"` (#321)
- **`skill-seekers doctor` command** — 8 diagnostic checks (Python version, package install, git, core/optional deps, API keys, MCP server, output dir) with pass/warn/fail status and `--verbose` flag (#316)
- **Prompt injection check workflow** — bundled `prompt-injection-check` workflow scans scraped content for injection patterns (role assumption, instruction overrides, delimiter injection, hidden instructions). Added as first stage in `default` and `security-focus` workflows. Flags suspicious content without removing it (#324)
- **Codex CLI plugin manifest** (`.codex-plugin/plugin.json`) for OpenAI Codex integration (#350)
- **6 behavioral UML diagrams** — 3 sequence (create pipeline, GitHub+C3.x flow, MCP invocation), 2 activity (source detection, enhancement pipeline), 1 component (runtime dependencies with interface contracts)
- **134 new tests** — `test_agent_client.py`, `test_config_publisher.py`, `_build_argv` tests. Total: 3194 passed, 39 expected skips (#336)

### Changed
- **All content extraction features enabled by default** — pattern detection, test examples, how-to guides, config extraction, and router generation no longer require explicit opt-in
- **Renamed `claude-enhanced` merge mode to `ai-enhanced`** — backward compatibility alias kept (#336)
- **Removed 118+ hardcoded Claude references** across 60+ files (#336)
- **Refactored 5 enhancers** to use `AgentClient` abstraction (#336)
- **Removed 50-file GitHub API analysis limit** (#336)
- **Removed 100-file config extraction limit** (#336)
- **Fixed unified scraper default `max_pages`** from 100 to 500 (#336)
- **Centralized enhancement timeouts** to 45min default with unlimited support (#336)
- **Excluded slow MCP/e2e tests from CI coverage step** to prevent timeout

### Fixed
- **`glob('*.md')` replaced with `rglob('*.md')`** in all adaptors — fixes packaging when skills are in nested directories (#349)
- **`scraped_data` list-vs-dict bug** in conflict detection (#336)
- **`base_url` passthrough** to doc scraper subprocess (#336)
- **URL filtering** now uses base directory correctly (#336)
- **C3.x analysis data loss** (#336)
- **`--enhance-level` flag** not passed correctly (#336)
- **`guide_enhancer` method rename** — `_call_claude_api` renamed to `_call_ai` (#336)
- **11 pre-existing test failures** fixed (#336)
- **Per-file language detection** in GitHub scraper (#336)
- **GitHub language detection crashes with `TypeError`** when API response contains non-integer metadata keys (e.g., `"url"`) — now filters to integer values only (#322)
- **C3.x codebase analysis crashes with `TypeError`** — `_run_c3_analysis()` and `_analyze_c3x()` passed removed `enhance_with_ai`/`ai_mode` kwargs to `analyze_codebase()` instead of `enhance_level` (#323)

### Security
- **Removed command injection** via cloned repo script execution (#336)
- **Replaced `git add -A`** with targeted staging in marketplace publisher (#336)
- **Clear auth tokens** from cached `.git/config` after clone (#336)
- **Use `defusedxml`** for sitemap XML parsing (XXE protection) (#336)
- **Path traversal validation** for config names (#336)

## [3.4.0] - 2026-03-21

### Added
- **OpenCode adaptor** (`--target opencode`) - Directory-based packaging with dual-format YAML frontmatter
- **OpenAI-compatible base class** - Shared base for all OpenAI-compatible LLM platforms
- **6 new LLM platform adaptors**: Kimi (`--target kimi`), DeepSeek (`--target deepseek`), Qwen (`--target qwen`), OpenRouter (`--target openrouter`), Together AI (`--target together`), Fireworks AI (`--target fireworks`)

- **Full UML architecture documentation** — 14 class diagrams synced from source code via StarUML
- **StarUML HTML API reference** documentation export
- **Ecosystem section** in README linking all Skill Seekers repos (PyPI, website, plugin, GitHub Action)

### Fixed
- **`sanitize_url()` crashes on Python 3.14** due to strict `urlparse` rejecting bracket-containing URLs (#284)
- **Blindly appending `/index.html.md` to non-.md URLs** — now only appends for URLs that should have it (#277)
- **Unified scraper temp config** uses unified format for `doc_scraper` instead of raw args (#317)
- **Unicode arrows in CLI help text** replaced with ASCII for Windows cp1252 compatibility
- **CLI flags in plugin slash commands** corrected (`create` uses `--preset`, `package` uses `--target`)
- **MiniMax adaptor** improvements from PR #318 review (#319)
- **Misleading "Scraped N pages" count** reported visited URLs instead of saved pages — now shows `(N saved, M skipped)` (#320)
- **"No scraped data found" after successful scrape** on JavaScript SPA sites — now warns that site requires JS rendering (#320, #321)

### Changed
- Refactored MiniMax adaptor to inherit from shared OpenAI-compatible base class
- Platform count: 5 → 12 LLM targets

### Added

#### 10 New Skill Source Types (17 total)

Skill Seekers now supports 17 source types — up from 7. Every new type is fully integrated into the CLI (`skill-seekers <type>`), `create` command auto-detection, unified multi-source configs, config validation, the MCP server, and the skill builder.

- **Jupyter Notebook** — `skill-seekers jupyter --notebook file.ipynb` or `skill-seekers create file.ipynb`
  - Extracts markdown cells, code cells with outputs, kernel metadata, imports, and language detection
  - Handles single files and directories of notebooks; filters `.ipynb_checkpoints`
  - Optional dependency: `pip install "skill-seekers[jupyter]"` (nbformat)
  - Entry point: `skill-seekers-jupyter`

- **Local HTML** — `skill-seekers html --html-path file.html` or `skill-seekers create file.html`
  - Parses HTML using BeautifulSoup with smart main content detection (`<article>`, `<main>`, `.content`, largest div)
  - Extracts headings, code blocks, tables (to markdown), images, links; converts inline HTML to markdown
  - Handles single files and directories; supports `.html`, `.htm`, `.xhtml` extensions
  - No extra dependencies (BeautifulSoup is a core dep)

- **OpenAPI/Swagger** — `skill-seekers openapi --spec spec.yaml` or `skill-seekers create spec.yaml`

  - Resolves `$ref` references with circular reference protection; handles `allOf`/`oneOf`/`anyOf`
  - Groups endpoints by tags; generates comprehensive API reference markdown
  - Source detection sniffs YAML file content for `openapi:` or `swagger:` keys (avoids false positives on non-API YAML files)
  - Optional dependency: `pip install "skill-seekers[openapi]"` (pyyaml — already a core dep, guard added for safety)

  - Parses RSS 2.0, RSS 1.0, and Atom feeds via feedparser
  - Optionally follows article links (`--follow-links`, default on) to scrape full page content using BeautifulSoup
  - Extracts article titles, summaries, authors, dates, categories; configurable `--max-articles` (default 50)
  - Source detection matches `.rss` and `.atom` extensions (`.xml` excluded to avoid false positives)
  - Optional dependency: `pip install "skill-seekers[rss]"` (feedparser)

- **Man Pages** — `skill-seekers manpage --man-names git,curl` / `--man-path dir/` or `skill-seekers create git.1`
  - Extracts man pages by running `man` command via subprocess or reading `.1`–`.8`/`.man` files directly
  - Handles gzip/bzip2/xz compressed man files; strips troff/groff formatting (backspace overstriking, macros, font escapes)
  - Parses structured sections (NAME, SYNOPSIS, DESCRIPTION, OPTIONS, EXAMPLES, SEE ALSO)

#### EPUB Unified Pipeline Integration
- **EPUB (.epub) input support** via `skill-seekers create book.epub` or `skill-seekers epub --epub book.epub`
  - Extracts chapters, metadata (Dublin Core), code blocks, images, and tables from EPUB 2 and EPUB 3 files

  - Optional dependency: `pip install "skill-seekers[epub]"` (ebooklib)
  - 107 tests across 14 test classes
- **EPUB added to unified scraper** — `_scrape_epub()` method, `scraped_data["epub"]`, config validation (`_validate_epub_source`), and dry-run display. Previously EPUB worked standalone but was missing from multi-source configs.

#### Unified Skill Builder — Generic Merge System
- **`_generic_merge()`** — Priority-based section merge for any combination of source types not covered by existing pairwise synthesis (docs+github, docs+pdf, etc.). Produces YAML frontmatter + source-attributed sections.
- **`_append_extra_sources()`** — Appends additional source type content (e.g., Jupyter + PPTX) to pairwise-synthesized SKILL.md.
- **`_generate_generic_references()`** — Generates `references/<type>/index.md` for any source type, with ID resolution fallback chain.
- **`_SOURCE_LABELS`** dict — Human-readable labels for all 17 source types used in merge attribution.

#### Config Validator Expansion
- **17 source types in `VALID_SOURCE_TYPES`** — All new types plus `word` and `video` now have per-type validation methods.
- **`_validate_word_source()`** — Validates `path` field for Word documents (was previously missing).
- **`_validate_video_source()`** — Validates `url`, `path`, or `playlist` field for video sources (was previously missing).
- **11 new `_validate_*_source()` methods** — One for each new type with appropriate required-field checks.

#### Source Detection Improvements
- **7 new file extension detections** in `SourceDetector.detect()` — `.ipynb`, `.html`/`.htm`, `.pptx`, `.adoc`/`.asciidoc`, `.rss`/`.atom`, `.1`–`.8`/`.man`, `.yaml`/`.yml` (with content sniffing)
- **`_looks_like_openapi()`** — Content sniffing for YAML files: only classifies as OpenAPI if the file contains `openapi:` or `swagger:` key in first 20 lines (prevents false positives on docker-compose, Ansible, Kubernetes manifests, etc.)
- **Man page basename heuristic** — `.1`–`.8` extensions only detected as man pages if the basename has no dots (e.g., `git.1` matches but `access.log.1` does not)
- **`.xml` excluded from RSS detection** — Too generic; only `.rss` and `.atom` trigger RSS detection

#### MCP Server Integration
- **`scrape_generic` tool** — New MCP tool handles all 10 new source types via subprocess with per-type flag mapping
- **`_PATH_FLAGS` / `_URL_FLAGS` dicts** — Correct flag routing for each source type (e.g., jupyter→`--notebook`, html→`--html-path`, rss→`--feed-url`)
- **`GENERIC_SOURCE_TYPES` tuple** — Lists all 10 new types for validation
- **Config validation display** — `validate_config` tool now shows source details for all new types
- **Tool count updated** — 33 → 34 tools (scraping tools 10 → 11)

#### CLI Wiring
- **10 new CLI subcommands** — `jupyter`, `html`, `openapi`, `asciidoc`, `pptx`, `rss`, `manpage`, `confluence`, `notion`, `chat` in `COMMAND_MODULES`
- **10 new argument modules** — `arguments/{jupyter,html,openapi,asciidoc,pptx,rss,manpage,confluence,notion,chat}.py` with per-type `*_ARGUMENTS` dicts
- **10 new parser modules** — `parsers/{jupyter,html,openapi,asciidoc,pptx,rss,manpage,confluence,notion,chat}_parser.py` with `SubcommandParser` implementations
- **`create` command routing** — `_route_generic()` method for all new types with correct module names and CLI flags
- **10 new entry points** in pyproject.toml — `skill-seekers-{jupyter,html,openapi,asciidoc,pptx,rss,manpage,confluence,notion,chat}`
- **7 new optional dependency groups** in pyproject.toml — `[jupyter]`, `[asciidoc]`, `[pptx]`, `[confluence]`, `[notion]`, `[rss]`, `[chat]`
- **`[all]` group updated** — Includes all 7 new optional dependencies

#### Sync Config Command
- **`skill-seekers sync-config`** — New subcommand that crawls a docs site's navigation, diffs discovered URLs against a config's `start_urls`, and optionally writes the updated list back with `--apply` (#306)
  - BFS link discovery with configurable depth (default 2), max-pages, rate-limit
  - Respects `url_patterns.include/exclude` from config
  - Supports optional `nav_seed_urls` config field
  - Handles both unified (sources array) and legacy flat config formats
  - MCP `sync_config` tool included
  - 57 tests (39 unit + 18 E2E with local HTTP server)

#### Workflow & Documentation
- **`complex-merge.yaml`** — New 7-stage AI-powered workflow for complex multi-source merging (source inventory → cross-reference → conflict detection → priority merge → gap analysis → synthesis → quality check)
- **AGENTS.md rewritten** — Updated with all 17 source types, scraper pattern docs, project layout, and key pattern documentation
- **77 new integration tests** in `test_new_source_types.py` — Source detection, config validation, generic merge, CLI wiring, validation, and create command routing
- **`docs/BEST_PRACTICES.md`** — Comprehensive guide for creating high-quality skills: SKILL.md structure, code examples, prerequisites, troubleshooting, quality targets, and real-world Grade F to Grade A example (#206)
- **Documentation updated for 17 source types** — 32 files updated across README, CLI reference, feature matrix, MCP reference, config format, API reference, unified scraping, multi-source guide, installation, quick-start, core concepts, user guide, FAQ, troubleshooting, architecture, and all Chinese (zh-CN) translations
- **README translations for 10 languages (12 total)** — Added Japanese (日本語), Korean (한국어), Spanish (Español), French (Français), German (Deutsch), Portuguese (Português), Turkish (Türkçe), Arabic (العربية), Hindi (हिन्दी), and Russian (Русский) README translations with language selector bar across all versions

### Performance
- **Pre-compiled regex and O(1) URL dedup in doc_scraper** — Module-level compiled patterns, `_enqueued_urls` set for O(1) dedup, cached URL patterns, async error logging fix (#309)
- **Bisect-based line indexing in code_analyzer and dependency_analyzer** — O(log n) `offset_to_line()` via bisect replaces O(n) `count("\n")` across all 10 language analyzers and all import extractors
- **O(n) parent class map for Python method detection** — Replaces O(n²) repeated AST walks in code_analyzer
- **O(1) tree traversal in github_scraper** — `deque.popleft()` replaces list `pop(0)`
- **Shared `build_line_index()` / `offset_to_line()` utilities** in `cli/utils.py` — DRY extraction from code_analyzer and dependency_analyzer

### Fixed
- **Config validator missing `word` and `video` dispatch** — `_validate_source()` had no `elif` branches for `word` or `video` types, silently skipping validation. Added dispatch entries and `_validate_word_source()` / `_validate_video_source()` methods.
- **`openapi_scraper.py` unconditional `import yaml`** — Would crash at import time if pyyaml not installed. Added `try/except ImportError` guard with `YAML_AVAILABLE` flag and `_check_yaml_deps()` helper.
- **`asciidoc_scraper.py` missing standard arguments** — `main()` manually defined args instead of using `add_asciidoc_arguments()`. Refactored to use shared argument definitions + added enhancement workflow integration.
- **`pptx_scraper.py` missing standard arguments** — Same issue. Refactored to use `add_pptx_arguments()`.
- **`chat_scraper.py` missing standard arguments** — Same issue. Refactored to use `add_chat_arguments()`.
- **`notion_scraper.py` missing `run_workflows` call** — `--enhance-workflow` flags were silently ignored. Added workflow runner integration.
- **`openapi_scraper.py` return type `None`** — `main()` returned `None` instead of `int`. Fixed to `return 0` on success, matching all other scrapers.
- **MCP `scrape_generic_tool` flag mismatch** — Was passing `--path`/`--url` as generic flags, but every scraper expects its own flag name (e.g., `--notebook`, `--html-path`, `--spec`). All 10 source types would have failed at runtime. Fixed with per-type `_PATH_FLAGS` and `_URL_FLAGS` mappings.
- **Word scraper `docx_id` key mismatch** — Unified scraper data dict used `docx_id` but generic reference generation looked for `word_id`. Added `word_id` alias.
- **`main.py` docstring stale** — Missing all 10 new commands. Updated to list all 27 commands.
- **`source_detector.py` module docstring stale** — Described only 5 source types. Updated to describe 14+ detected types.
- **`manpage_parser.py` docstring referenced wrong file** — Said `manpage_scraper.py` but actual file is `man_scraper.py`. Fixed.
- **Parser registry test count** — Updated expected count from 25 to 35 for 10 new parsers.
- **'Invalid IPv6 URL' error on bracket-containing URLs (#284)** — URLs with square brackets (e.g., `/api/[v1]/users`) discovered via BFS crawl or HTML extraction bypassed the original fix in `_clean_url()`. Added shared `sanitize_url()` utility applied at every URL ingestion point. 16 new tests.
- **GitHub scraper 'list index out of range' on issue extraction (#269)** — PyGithub's `PaginatedList` slicing could fail on some versions or empty repos. Replaced with `itertools.islice()`.
- **Release workflow version mismatch** — GitHub release showed wrong version (v3.1.3 instead of v3.2.0) because no explicit release name was set and sed regex had unescaped dots. Added explicit `name`/`tag_name`, version consistency check (tag vs pyproject.toml vs package), and empty release notes fallback.
- **Release workflow Python 3.10 compatibility** — Version consistency check used `tomllib` (Python 3.11+). Replaced with grep/sed for 3.10 compatibility.
- **`infer_categories()` "tutorial" vs "tutorials" key mismatch** — Guard checked `'tutorial'` but wrote to `'tutorials'` key, risking silent overwrites in category inference.
- **Flaky `test_benchmark_metadata_overhead`** — Stabilized with 20 iterations, warm-up run, median averaging, and 200% threshold (was failing on CI with 5 iterations and mean).
- **CI branch protection check permanently pending** — Summary job was named 'All Checks Complete' but branch protection required 'Tests'. PRs were stuck as 'Expected — Waiting for status to be reported'. Renamed job to match.

## [3.2.0] - 2026-03-01

**Theme:** Video source support, Word document support, Pinecone adaptor, and quality improvements. 94 files changed, +23,500 lines since v3.1.3. **2,540 tests passing.**

### 🎬 Video Tutorial Scraping Pipeline (BETA)

Complete video tutorial extraction system that converts YouTube videos and local video files into AI-consumable skills. The pipeline extracts transcripts, performs visual OCR on code editor panels, tracks code evolution across frames, and generates structured SKILL.md output.

### Added

### Fixed

#### Video Pipeline OCR Quality Fixes (6)
- **Webcam/OTHER frames skip OCR** — WEBCAM and OTHER frame types no longer get OCR'd, eliminating ~64 junk OCR results per video
- **`_clean_ocr_line()` helper** — Strips leading line numbers, IDE tab bar text, Unity Inspector labels, and VS Code collapse markers from OCR output
- **`_fix_intra_line_duplication()`** — Detects and removes token sequence repetition from multi-engine OCR overlap (e.g., `gpublic class Card Jpublic class Card` → `public class Card`)
- **`_is_likely_code()` filter** — Reference file code fences now filtered to reject UI junk (Inspector, Hierarchy, Canvas labels) that passed frame classification
- **Language detection on text groups** — `get_text_groups()` now runs `LanguageDetector.detect_from_code()` on each group, filling the previously-always-None `detected_language` field
- **OCR cleaning in text assembly** — `_assemble_structured_text()` applies `_clean_ocr_line()` to every line before joining

#### Video Pipeline Fixes (15)
- **`extract_visual_data` returning 2-tuple instead of 3** — Caused `ValueError` crash when unpacking results
- **pytesseract in core deps** — Moved from core dependencies to `[video-full]` optional group
- **30-min timeout for video enhancement subprocess** — Previously could hang indefinitely
- **`scrape_video_impl` missing from MCP server fallback import** — Added to import block
- **Auto-generated YouTube captions not detected** — Now checks `is_generated` property on transcripts
- **`--vision-ocr` and `--video-playlist` not forwarded** — `create` command now passes these to video scraper
- **Filename collision for non-ASCII video titles** — Falls back to `video_id` when title contains non-ASCII characters
- **`_vision_used` not a proper dataclass field** — Made a proper field on `FrameSubSection` dataclass
- **6 visual params missing from MCP `scrape_video`** — Exposed keyframe_threshold, max_keyframes, whisper_model, vision_ocr, video_playlist, video_file
- **Missing video dep install instructions in unified scraper** — Added guidance when video dependencies are not installed
- **MCP docstring tool counts outdated** — Updated from 25→33 tools across 7 categories
- **Video and word commands missing from `main.py` docstring** — Added to CLI help text
- **`video-full` exclusion from `[all]` deps undocumented** — Added comment in pyproject.toml
- **Parser registry test count wrong** — Updated expected count from 22→23 for video parser

#### Scraper & Quality Fixes
- **Issue #300: Selector fallback & dry-run link discovery** — `create https://reactflow.dev/` now finds 20+ pages (was 1):
  - `extract_content()` extracted links after early-return → moved before
  - Dry-run used `main.find_all("a")` instead of `soup.find_all("a")` → fixed
  - Async dry-run had no link extraction at all → added
  - `get_configuration()` CSS comma selector conflicted with fallback loop → removed default
  - `create --config` with `base_url` config incorrectly routed to unified_scraper → now peeks at JSON
  - Selector fallback duplicated in 3 places with `body` fallback → extracted `FALLBACK_MAIN_SELECTORS` constant + `_find_main_content()` helper
- **Issue #301: `setup.sh` fails on macOS** — `pip3` pointed to different Python than `python3`. Changed to `python3 -m pip`.
- **RAG chunking crash (`AttributeError: output_dir`)** — `converter.output_dir` doesn't exist on `DocToSkillConverter`. Changed to `Path(converter.skill_dir)`.
- **`--var` flag silently dropped in `create` routing** — `main.py` read `args.workflow_var` instead of `args.var`
- **`--chunk-overlap-tokens` missing from `package` command** — Wired through entire pipeline: `package_skill()` → `adaptor.package()` → `format_skill_md()` → `_maybe_chunk_content()` → `RAGChunker`
- **Chunk overlap auto-scaling** — Auto-scales to `max(50, chunk_tokens // 10)` when chunk size is non-default
- **Weaviate `ImportError` masked by generic handler** — Added `except ImportError` before `except Exception`
- **Hardcoded chunk defaults in 12 adaptors** — Replaced `512`/`50` with `DEFAULT_CHUNK_TOKENS`/`DEFAULT_CHUNK_OVERLAP_TOKENS` constants
- **Reference file code truncation** — `codebase_scraper.py` no longer truncates code blocks to 500 chars (5 locations)
- **Enhancement code block limit** — `summarize_reference()` now uses character-budget approach instead of `[:5]` cap
- **Intro boundary code block desync** — Tracks code block state to prevent splitting inside code blocks
- **Hardcoded `python` language** — `unified_skill_builder.py` and `how_to_guide_builder.py` now use detected language
- **GitHub reference file limits removed** — No more caps on issues (was 20), releases (was 10), or release bodies (was 500 chars)
- **GitHub scraper reference limits removed** — `github_scraper.py` no longer caps open_issues at 20 or closed_issues at 10
- **PDF scraper fixes** — Real API/LOCAL enhancement (was stub); removed `[:3]` reference file limit
- **Word scraper code detection** — Detect mammoth monospace `<p><br>` blocks as code
- **Language detector method** — Fixed `detect_from_text` → `detect_from_code` in word scraper
- **`.docx` file extension validation** — Non-`.docx` files raise `ValueError` with clear message
- **Double `_score_code_quality()` call** — Consolidated to single call in word scraper
- **`--no-preserve-code` renamed** — Now `--no-preserve-code-blocks` (backward-compat alias kept)
- **Dead variable** — Removed unused `_target_lines` in `enhance_skill_local.py`

### Changed
- **`easyocr` removed from `video-full` optional deps** — Was pulling ~2GB of NVIDIA CUDA packages regardless of GPU vendor. Now installed via `--setup` with correct PyTorch variant.
- **Video dependency error messages** — `video_scraper.py` and `video_visual.py` now suggest `skill-seekers video --setup` as primary fix
- **Shared embedding methods consolidated** — `_generate_openai_embeddings()` and `_generate_st_embeddings()` moved to `SkillAdaptor` base class, eliminating ~150 lines of duplication from chroma/weaviate/pinecone adaptors
- **Chunk constants centralized** — `DEFAULT_CHUNK_TOKENS = 512` and `DEFAULT_CHUNK_OVERLAP_TOKENS = 50` in `arguments/common.py`, used across all 12 adaptors + rag_chunker + base + package_skill + create_command
- **Enhancement summarizer architecture** — Character-budget approach with `target_ratio` for both code blocks and heading chunks

## [3.1.3] - 2026-02-24

### 🐛 Hotfix — Explicit Chunk Flags & Argument Pipeline Cleanup

### Fixed
- **Issue #299: `skill-seekers package --target claude` unrecognised argument crash** — `_reconstruct_argv()` in `main.py` emits default flag values back into argv when routing subcommands. `package_skill.py` had a 105-line inline argparser that used different flag names to those in `arguments/package.py`, so forwarded flags were rejected. Fixed by replacing the inline block with a call to `add_package_arguments(parser)` — the single source of truth.

### Changed
- **`package_skill.py` argparser refactored** — Replaced ~105 lines of inline argparse duplication with a single `add_package_arguments(parser)` call. Flag names are now guaranteed consistent with `_reconstruct_argv()` output, preventing future argument-name drift.
- **Explicit chunk flag names** — All `--chunk-*` flags now include unit suffixes to eliminate ambiguity between RAG tokens and streaming characters:
  - `--chunk-size` (RAG tokens) → `--chunk-tokens`
  - `--chunk-overlap` (RAG tokens) → `--chunk-overlap-tokens`
  - `--chunk` (enable RAG chunking) → `--chunk-for-rag`
  - `--streaming-chunk-size` (chars) → `--streaming-chunk-chars`
  - `--streaming-overlap` (chars) → `--streaming-overlap-chars`
  - `--chunk-size` in PDF extractor (pages) → `--pdf-pages-per-chunk`
- **`setup_logging()` centralized** — Added `setup_logging(verbose, quiet)` to `utils.py` and removed 4 duplicate module-level `logging.basicConfig()` calls from `doc_scraper.py`, `github_scraper.py`, `codebase_scraper.py`, and `unified_scraper.py`

## [3.1.2] - 2026-02-24

### 🔧 Fix `create` Command Argument Forwarding, Gemini Model, and Enhance Dispatcher

### Fixed
- **`create` command argument forwarding** — Universal flags (`--dry-run`, `--verbose`, `--quiet`, `--name`, `--description`) now work correctly across all source types. Previously, `create <url> -p quick --dry-run`, `create owner/repo --dry-run`, and `create ./path --dry-run` would crash because sub-scrapers didn't accept those flags
- **`skill-seekers analyze --dry-run`** — Fixed `_handle_analyze_command()` in `main.py` not forwarding `--dry-run`, `--preset`, `--quiet`, `--name`, `--description`, `--api-key`, and workflow flags to codebase_scraper
- **Gemini model 404 errors** — Replaced retired `gemini-2.0-flash-exp` with `gemini-2.5-flash` (stable GA) in the Gemini adaptor. Users attempting Gemini enhancement were getting 404 Not Found errors
- **`skill-seekers enhance` auto-detection** — The documented behaviour of auto-detecting API vs LOCAL mode was never implemented. `enhance` now correctly routes to the platform API when a key is present: `ANTHROPIC_API_KEY` → Claude API, `GOOGLE_API_KEY` → Gemini API, `OPENAI_API_KEY` → OpenAI API, no key → LOCAL mode (Claude Code Max, free). Use `--mode LOCAL` to force local mode regardless

### Added
- **Shared argument contract** — New `add_all_standard_arguments(parser)` in `arguments/common.py` registers common + behavior + workflow args on any parser as a single call
- **`BEHAVIOR_ARGUMENTS`** — Centralized `--dry-run`, `--verbose`, `--quiet` definitions in `arguments/common.py`
- **`--dry-run` for GitHub scraper** — `skill-seekers github --repo owner/repo --dry-run` now previews the operation
- **`--dry-run` for PDF scraper** — `skill-seekers pdf --name test --dry-run` now previews the operation
- **`--verbose`/`--quiet` for GitHub and PDF scrapers** — Logging level control now works consistently across all scrapers
- **`--name`/`--description` for codebase analyzer** — Custom skill name and description can now be passed to `skill-seekers analyze`
- **`--mode LOCAL` flag for `skill-seekers enhance`** — Explicitly forces LOCAL mode even when API keys are present

### Changed
- **Argument deduplication** — Removed duplicated argument definitions from `arguments/github.py`, `arguments/scrape.py`, `arguments/analyze.py`, `arguments/pdf.py`; all now import shared args from `arguments/common.py`
- **`create` command `_add_common_args()`** — Only forwards truly universal flags; route-specific flags (`--preset`, `--config`, `--chunk-for-rag`, etc.) moved to their respective route methods
- **`codebase_scraper.py` argparser** — Replaced ~190 lines of inline argparser with `add_analyze_arguments(parser)` call

## [3.1.1] - 2026-02-23

### 🐛 Hotfix

### Fixed
- **`create` command `max_pages` AttributeError** — Fixed crash when `max_pages` argument was not provided in web source routing. Uses `getattr()` for safe attribute access (#293, #294)

### Changed
- Version bump to 3.1.1

## [3.1.0] - 2026-02-23

### 🎯 "Unified CLI & Developer Experience" — Feature Release

**Theme:** One command for everything. Better developer tooling. 2280+ tests passing.

### Added

#### Unified `create` Command
- **Single command for all source types** — auto-detects URL, GitHub repo (`owner/repo`), local directory, PDF file, or multi-source config JSON
  ```bash
  skill-seekers create https://docs.react.dev/
  skill-seekers create facebook/react
  skill-seekers create ./my-project
  skill-seekers create tutorial.pdf
  ```
- **Progressive help disclosure** — default `--help` shows 13 universal flags; detailed help per source:
  - `--help-web`, `--help-github`, `--help-local`, `--help-pdf`, `--help-advanced`, `--help-all`
- **`-p` shortcut** for preset selection: `skill-seekers create <source> -p quick|standard|comprehensive`
- **`--local-repo-path`** flag for specifying local clone path in create command with validation
- Supports multi-source config files as input (routes to unified scraper)

#### Enhancement Workflow Preset System
- **New `workflows` CLI subcommand** to manage enhancement workflow presets
- **65 bundled workflow presets** shipped as YAML files in `skill_seekers/workflows/`:
  - Core: `default`, `minimal`, `security-focus`, `architecture-comprehensive`, `api-documentation`

  - Mobile: `push-notifications`, `offline-first`, `localization-i18n`
  - Background: `background-jobs`, `rate-limiting`, `caching-strategies`, `webhook-guide`, `api-gateway`
- 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 if any item fails)
- New entry point: `skill-seekers-workflows`

#### Multiple `--enhance-workflow` Flags from CLI
- Chain workflows in a single command: `skill-seekers create <source> --enhance-workflow security-focus --enhance-workflow minimal`
- Supported across all scrapers: `scrape`, `github`, `analyze`, `pdf`, `unified`

#### Smart Enhancement Dispatcher (`skill-seekers enhance`)
- Auto-routes to API mode (Claude/Gemini/OpenAI) when API key is available, LOCAL mode (Claude Code CLI) otherwise
- Decision priority: `--target` flag → config `default_agent` → env vars (`ANTHROPIC_API_KEY` → claude, `GOOGLE_API_KEY` → gemini, `OPENAI_API_KEY` → openai) → LOCAL fallback
- **Blocks LOCAL mode when running as root** (Docker/VPS) with clear error message + API mode instructions (fixes #286, #289)
- New flags: `--target`, `--api-key`, `--dry-run`, `--interactive-enhancement`

#### Unified Document Parser System
- New `parsers/extractors.py` module with `RstParser`, `MarkdownParser` classes
- **ReStructuredText (RST) support** — parses class references, code blocks, tables, cross-references
- Shared `parse_document()` factory function for RST/Markdown/PDF input
- Integrated into documentation extraction pipeline for richer content
- `ContentBlockType` and `CrossRefType` enums for structured parsing output

#### Local Source Support in Unified Scraper
- `"type": "local"` source type in unified config JSONs — analyze local codebases alongside web/GitHub/PDF sources
- `--local-repo-path` CLI flag in unified scraper for per-source path override

#### CLI Flag Parity Across All Commands
- `analyze`, `pdf`, and `unified` commands now have full flag parity with `scrape`/`github`:
  - `--api-key` on `pdf` and `unified`
  - `--enhance-level` on `unified`
  - `--dry-run` on `analyze`
  - All workflow flags (`--enhance-workflow`, `--enhance-stage`, `--var`, `--workflow-dry-run`) on `analyze`
- Workflow JSON config fields (`workflows`, `workflow_stages`, `workflow_vars`) now merged with CLI flags in `unified` scraper

### Fixed
- **Percent-encode brackets in llms.txt URLs** — prevent "Invalid IPv6 URL" errors when scraping sites with bracket characters (fixes #284)
- **Platform-appropriate config paths on Windows** — use `%APPDATA%` instead of `~/.config` (fixes #283)
- **`create` command multi-source config** — now correctly routes to unified scraper when input is a `.json` config file
- **`create` command `_add_common_args()`** — correctly forwards each `--enhance-workflow` value as a separate flag to sub-scrapers (previously collapsed list to single string, causing workflows to be ignored)
- **`_extract_markdown_content`** — filter out bare `h1` headings and short stub paragraphs that polluted extracted content
- **Godot unified config language names** — corrected `gdscript`/`gds` to proper names in `godot_unified.json`
- **Python 3.10 type union compatibility** — use `Optional[X]` instead of `X | None` in forward-reference positions
- **`_route_config` in unified scraper** — correctly handles all source types when routing config-driven scraping
- **CONFIG_ARGUMENTS** — added to ensure unified CLI has full argument visibility for config-based sources
- **Test suite isolation** — `test_swift_detection.py` now saves/restores `sys.modules` and parent package attributes; prevents `@patch` decorators in downstream files from targeting stale module objects
- **Python 3.14 chromadb compatibility** — catch `pydantic.v1.errors.ConfigError` (not just `ImportError`) when chromadb is installed
- **langchain import path** — updated `langchain.schema` → `langchain_core.documents` for langchain 1.x
- **Removed legacy `sys.path.insert()` calls** from `codebase_scraper.py`, `doc_scraper.py`, `enhance_skill.py`, `enhance_skill_local.py`, `estimate_pages.py`, `install_skill.py` (unnecessary with `pip install -e .`)
- **Benchmark timing threshold** — relaxed metadata overhead assertion from 10% to 50% for CI runner variability

### Changed
- **Enhancement flags consolidated** — `--enhance-level` (0-3) replaces three separate flags (`--enhance`, `--enhance-local`, `--api-key`). Old flags still accepted with deprecation warnings until v4.0.0
- **`workflows copy/add/remove`** now accept multiple names/files in one invocation
- **`pyproject.toml`** — PyYAML added as core dependency (required by workflow preset management); langchain and llama-index added as dependencies; MCP version requirement updated to `>=1.25`

### Tests
- **2280+ tests passing** (2158 non-MCP + ~122 MCP, up from 1852 in v3.0.0), 11 skipped (external services), 0 failures
- Added `TestAnalyzeWorkflowFlags`, `TestUnifiedCLIArguments`, `TestPDFCLIArguments` classes
- Added `tests/test_mcp_workflow_tools.py` — 5 MCP workflow tool tests
- Added `tests/test_unified_scraper_orchestration.py` — UnifiedScraper orchestration tests
- Removed `@unittest.skip` from gemini/openai/claude adaptor tests that were ready
- Removed `@requires_github` from 5 unified_analyzer tests that fully mock their dependencies
- Macros-specific tests now use `@patch(sys.platform)` instead of runtime `skipTest()` for platform portability

### Config Repository (skill-seekers-configs)
- **178 production configs reviewed and enhanced** across all 22 categories — brought to v1.1.0 quality standard
- **Removed all `max_pages` fields** from production configs (deprecated, defaults apply automatically)
- **Fixed outdated URLs**: `astro.json` (Astro v3 restructure: `/en/core-concepts/` → `/en/basics/`), `laravel.json` (11.x → 12.x throughout)
- **Fixed structural bug** in `httpx_comprehensive.json` — `url_patterns`, `categories`, `rate_limit` moved from top-level into `sources[0]` (required for unified format)
- **Removed hash-fragment start_urls** from `zod.json` (scrapers don't follow `?id=` anchors)
- **Improved category/selector quality** across all 22 categories: 5-13 categories per config, 3-6 keywords each, semantic selector fallback chains
- **README.md**: corrected config count from outdated "50+" to accurate 178 production / 182 total; all category counts verified
- **CONTRIBUTING.md, QUALITY_GUIDELINES.md, AGENTS.md**: aligned with production standards; removed all `max_pages` guidance
- **`scripts/validate-config.py`**: fixed two bugs — unified config categories lookup (was always reporting "no categories" for multi-source configs) and `max_pages` warning logic (was warning when absent, now correctly warns when present)
- **Deleted** `.github/ISSUE_TEMPLATE/submit-config.md` (old duplicate of `submit-config.yml` with outdated content)

### 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

- **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

  - 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)

  - 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")
```
