# AGENTS.md - Skill Seekers

Concise reference for AI coding agents. Skill Seekers is a Python CLI tool (v3.3.0) that converts documentation sites, GitHub repos, PDFs, videos, notebooks, wikis, and more into AI-ready skills for 16+ LLM platforms and RAG pipelines.

## Setup

```bash
# REQUIRED before running tests (src/ layout — tests hard-exit if package not installed)
pip install -e .
# With dev tools (pytest, ruff, mypy, coverage)
pip install -e ".[dev]"
# With all optional deps
pip install -e ".[all]"
```

Note: `tests/conftest.py` checks that `skill_seekers` is importable and calls `sys.exit(1)` if not. Always install in editable mode first.

## Build / Test / Lint Commands

```bash
# Run ALL tests (never skip tests — all must pass before commits)
pytest tests/ -v

# Run a single test file
pytest tests/test_scraper_features.py -v

# Run a single test function
pytest tests/test_scraper_features.py::test_detect_language -v

# Run a single test class method
pytest tests/test_adaptors/test_claude_adaptor.py::TestClaudeAdaptor::test_package -v

# Skip slow/integration tests
pytest tests/ -v -m "not slow and not integration"

# With coverage
pytest tests/ --cov=src/skill_seekers --cov-report=term

# Lint (ruff)
ruff check src/ tests/
ruff check src/ tests/ --fix

# Format (ruff)
ruff format --check src/ tests/
ruff format src/ tests/

# Type check (mypy)
mypy src/skill_seekers --show-error-codes --pretty
```

**Pytest config** (from pyproject.toml): `addopts = "-v --tb=short --strict-markers"`, `asyncio_mode = "auto"`, `asyncio_default_fixture_loop_scope = "function"`.
**Test markers:** `slow`, `integration`, `e2e`, `venv`, `bootstrap`, `benchmark`, `asyncio`.
**Async tests:** use `@pytest.mark.asyncio`; asyncio_mode is `auto` so the decorator is often implicit.
**Test count:** 123 test files (107 in `tests/`, 16 in `tests/test_adaptors/`).

## Code Style

### Formatting Rules (ruff — from pyproject.toml)
- **Line length:** 100 characters
- **Target Python:** 3.10+
- **Enabled lint rules:** E, W, F, I, B, C4, UP, ARG, SIM
- **Ignored rules:** E501 (line length handled by formatter), F541 (f-string style), ARG002 (unused method args for interface compliance), B007 (intentional unused loop vars), I001 (formatter handles imports), SIM114 (readability preference)

### Imports
- Sort with isort (via ruff); `skill_seekers` is first-party
- Standard library → third-party → first-party, separated by blank lines
- Use `from __future__ import annotations` only if needed for forward refs
- Guard optional imports with try/except ImportError (see `adaptors/__init__.py` pattern):
  ```python
  try:
      from .claude import ClaudeAdaptor
      from .minimax import MiniMaxAdaptor
  except ImportError:
      ClaudeAdaptor = None
      MiniMaxAdaptor = None
  ```

### Naming Conventions
- **Files:** `snake_case.py` (e.g., `source_detector.py`, `config_validator.py`)
- **Classes:** `PascalCase` (e.g., `SkillAdaptor`, `ClaudeAdaptor`, `SourceDetector`)
- **Functions/methods:** `snake_case` (e.g., `get_adaptor()`, `detect_language()`)
- **Constants:** `UPPER_CASE` (e.g., `ADAPTORS`, `DEFAULT_CHUNK_TOKENS`, `VALID_SOURCE_TYPES`)
- **Private:** prefix with `_` (e.g., `_read_existing_content()`, `_validate_unified()`)

### Type Hints
- Gradual typing — add hints where practical, not enforced everywhere
- Use modern syntax: `str | None` not `Optional[str]`, `list[str]` not `List[str]`
- MyPy config: `disallow_untyped_defs = false`, `check_untyped_defs = true`, `ignore_missing_imports = true`
- Tests are excluded from strict type checking (`disallow_untyped_defs = false`, `check_untyped_defs = false` for `tests.*`)

### Docstrings
- Module-level docstring on every file (triple-quoted, describes purpose)
- Google-style docstrings for public functions/classes
- Include `Args:`, `Returns:`, `Raises:` sections where useful

### Error Handling
- Use specific exceptions, never bare `except:`
- Provide helpful error messages with context
- Use `raise ValueError(...)` for invalid arguments, `raise RuntimeError(...)` for state errors
- Guard optional dependency imports with try/except and give clear install instructions on failure
- Chain exceptions with `raise ... from e` when wrapping

### Suppressing Lint Warnings
- Use inline `# noqa: XXXX` comments (e.g., `# noqa: F401` for re-exports, `# noqa: ARG001` for required but unused params)

## Project Layout

```

    adaptors/                # Platform adaptors (Strategy pattern, inherit SkillAdaptor)

```

## Key Patterns

**Adaptor (Strategy) pattern** — all platform logic in `cli/adaptors/`. Inherit `SkillAdaptor`, implement `format_skill_md()`, `package()`, `upload()`. Register in `adaptors/__init__.py` ADAPTORS dict.

**Scraper pattern** — each source type has: `cli/<type>_scraper.py` (with `<Type>ToSkillConverter` class + `main()`), `arguments/<type>.py`, `parsers/<type>_parser.py`. Register in `parsers/__init__.py` PARSERS list, `main.py` COMMAND_MODULES dict, `config_validator.py` VALID_SOURCE_TYPES set.

**Unified pipeline** — `unified_scraper.py` dispatches to per-type `_scrape_<type>()` methods. `unified_skill_builder.py` uses pairwise synthesis for docs+github+pdf combos and `_generic_merge()` for all other combinations.

**MCP tools** — grouped in `mcp/tools/` by category. `scrape_generic_tool` handles all new source types.

**CLI subcommands** — git-style in `cli/main.py`. Each delegates to a module's `main()` function.

**Supported source types (17):** documentation (web), github, pdf, word, epub, video, local codebase, jupyter, html, openapi, asciidoc, pptx, rss, manpage, confluence, notion, chat (slack/discord). Each detected automatically by `source_detector.py`.

## Git Workflow

- **`main`** — production, protected
- **`development`** — default PR target, active dev
- Feature branches created from `development`

## Pre-commit Checklist

```bash
ruff check src/ tests/
ruff format --check src/ tests/
pytest tests/ -v -x   # stop on first failure
```

Never commit API keys. Use env vars: `ANTHROPIC_API_KEY`, `GOOGLE_API_KEY`, `OPENAI_API_KEY`, `GITHUB_TOKEN`.

## CI

GitHub Actions (7 workflows in `.github/workflows/`):
- **tests.yml** — ruff + mypy lint job, then pytest matrix (Ubuntu + macOS, Python 3.10-3.12) with Codecov upload
- **release.yml** — tag-triggered: tests → version verification → PyPI publish via `uv build`
- **test-vector-dbs.yml** — tests vector DB adaptors (weaviate, chroma, faiss, qdrant)
- **docker-publish.yml** — multi-platform Docker builds (amd64, arm64) for CLI + MCP images
- **quality-metrics.yml** — quality analysis with configurable threshold
- **scheduled-updates.yml** — weekly skill updates for popular frameworks
- **vector-db-export.yml** — weekly vector DB exports
