Luong NGUYEN 6d1e0ae4af refactor(ci): shift quality checks to pre-commit, CI as 2nd pass (#34)
* refactor(ci): shift quality checks to pre-commit, CI as 2nd pass

- Remove ci.yml (lint, security, pytest were only for EPUB scripts)
- Move EPUB build to pre-commit local hook (runs on .md changes)
- Add check_cross_references.py, check_mermaid.py, check_links.py scripts
- Add markdown-lint, cross-references, mermaid-syntax, link-check as
  pre-commit hooks — mirrors all 4 CI doc-check jobs locally
- Remove spell check job from docs-check.yml (breaks on translations)
- Refactor docs-check.yml to reuse scripts/ instead of inline Python
- Add .markdownlint.json config shared by pre-commit and CI
- Update CONTRIBUTING.md with required dependencies and hook table

* fix(ci): resolve all CI check failures in docs-check workflow

- fix(check_cross_references): skip code blocks and inline code spans
  to avoid false positives from documentation examples; fix emoji
  heading anchor generation (rstrip not strip); add blog-posts,
  openspec, prompts, .agents to IGNORE_DIRS; ignore README.backup.md
- fix(check_links): strip trailing Markdown punctuation from captured
  URLs; add wikipedia, api.github.com to SKIP_DOMAINS; add placeholder
  URL patterns to SKIP_URL_PATTERNS; add .agents/.claude to IGNORE_DIRS
- fix(check_mermaid): add --no-sandbox puppeteer config support via
  MERMAID_PUPPETEER_NO_SANDBOX env var for GitHub Actions Linux runners
- fix(docs-check.yml): pass MERMAID_PUPPETEER_NO_SANDBOX=true to mermaid job
- fix(content): repair broken anchors in README.md, 09-advanced-features;
  fix #plugins -> #claude-code-plugins in claude_concepts_guide.md;
  remove non-existent ./docs/performance.md placeholder links; fix
  dependabot alerts URL in SECURITY_REPORTING.md; update auto-mode URL
  in resources.md; use placeholder pattern for 07-plugins example URL
- remove README.backup.md (stale file)

* fix(check-scripts): fix strip_code_blocks regex and URL fragment handling

- fix regex in strip_code_blocks to avoid conflicting MULTILINE+DOTALL
  flags that could fail to strip indented code fences; use DOTALL only
- strip URL fragments (#section) before dispatching link checks to avoid
  false-positive 404s on valid URLs with anchor fragments

* fix(check-scripts): fix anchor stripping, cross-ref enforcement, and mermaid temp file cleanup

- heading_to_anchor: use .strip("-") instead of .rstrip("-") to also strip leading hyphens
  produced by emoji-prefixed headings, preventing false-positive anchor errors
- check_cross_references: always exit with main()'s return code — filesystem checks
  should block pre-commit unconditionally, not silently pass on errors
- check_mermaid: wrap file-processing loop in try/finally so the puppeteer config
  temp file is cleaned up even if an unexpected exception (e.g. UnicodeDecodeError) occurs
- docs-check.yml: remove now-unused CROSS_REF_STRICT env var

* fix(scripts): fix anchor stripping and mermaid output path

- Replace .strip('-') with .rstrip('-') in heading_to_anchor() so leading
  hyphens from emoji-prefixed headings are preserved, matching GitHub's
  anchor generation behaviour.
- Use Path.with_suffix('.svg') in check_mermaid.py instead of
  str.replace('.mmd', '.svg') to avoid replacing all occurrences of .mmd
  in the full temp path.

Claude How To

EPUB Builder Script

Build an EPUB ebook from the Claude How-To markdown files.

Features

  • Organizes chapters by folder structure (01-slash-commands, 02-memory, etc.)
  • Renders Mermaid diagrams as PNG images via Kroki.io API
  • Async concurrent fetching - renders all diagrams in parallel
  • Generates a cover image from the project logo
  • Converts internal markdown links to EPUB chapter references
  • Strict error mode - fails if any diagram cannot be rendered

Requirements

  • Python 3.10+
  • uv
  • Internet connection for Mermaid diagram rendering

Quick Start

# Simplest way - uv handles everything
uv run scripts/build_epub.py

Development Setup

# Create virtual environment
uv venv

# Activate and install dependencies
source .venv/bin/activate
uv pip install -r requirements-dev.txt

# Run tests
pytest scripts/tests/ -v

# Run the script
python scripts/build_epub.py

Command-Line Options

usage: build_epub.py [-h] [--root ROOT] [--output OUTPUT] [--verbose]
                     [--timeout TIMEOUT] [--max-concurrent MAX_CONCURRENT]

options:
  -h, --help            show this help message and exit
  --root, -r ROOT       Root directory (default: repo root)
  --output, -o OUTPUT   Output path (default: claude-howto-guide.epub)
  --verbose, -v         Enable verbose logging
  --timeout TIMEOUT     API timeout in seconds (default: 30)
  --max-concurrent N    Max concurrent requests (default: 10)

Examples

# Build with verbose output
uv run scripts/build_epub.py --verbose

# Custom output location
uv run scripts/build_epub.py --output ~/Desktop/claude-guide.epub

# Limit concurrent requests (if rate-limited)
uv run scripts/build_epub.py --max-concurrent 5

Output

Creates claude-howto-guide.epub in the repository root directory.

The EPUB includes:

  • Cover image with project logo
  • Table of contents with nested sections
  • All markdown content converted to EPUB-compatible HTML
  • Mermaid diagrams rendered as PNG images

Running Tests

# With virtual environment
source .venv/bin/activate
pytest scripts/tests/ -v

# Or with uv directly
uv run --with pytest --with pytest-asyncio \
    --with ebooklib --with markdown --with beautifulsoup4 \
    --with httpx --with pillow --with tenacity \
    pytest scripts/tests/ -v

Dependencies

Managed via PEP 723 inline script metadata:

Package Purpose
ebooklib EPUB generation
markdown Markdown to HTML conversion
beautifulsoup4 HTML parsing
httpx Async HTTP client
pillow Cover image generation
tenacity Retry logic

Troubleshooting

Build fails with network error: Check internet connectivity and Kroki.io status. Try --timeout 60.

Rate limiting: Reduce concurrent requests with --max-concurrent 3.

Missing logo: The script generates a text-only cover if claude-howto-logo.png is not found.
