Deletes the backup file that contains a list of scripts.
This action streamlines the repository and avoids potential
confusion or conflicts arising from outdated file lists.
Replaced external check-json hook with custom validator using Python's
built-in json module (json.load). Created validate_json.py wrapper to
handle multiple files.
Benefits:
- No external dependencies
- Uses Python's standard library json parser
- Same validation logic as the build system
- Fast and reliable (0.16s for all JSON files)
- Add generate_alt_text.py script for automated image alt-text generation
- Add README_ALT_TEXT.md with detailed usage instructions
- Add QUICK_START_ALT_TEXT.md for quick reference
- Uses Google Gemini API to generate descriptive alt-text for figures
Related to accessibility improvements for image descriptions.
Work in progress - requires GitHub issue tracking.
Addresses #1034
Fixed 47 instances across 20 quiz files where MCQ answer explanations
incorrectly referenced the correct option as one of the incorrect options.
Changes:
1. Fixed all quiz JSON files with incorrect option references
- Fixed patterns like 'Options A, C, and D' when A is correct
- Fixed patterns like 'Option C is incorrect' when C is correct
- Fixed patterns like 'Option A describes...' when A is correct
2. Created fix_mcq_answer_explanations.py script
- Automatically detects and fixes incorrect option references
- Handles plural and singular patterns
- Can be run on all quiz files or specific files
3. Enhanced quizzes.py with validation and opt-in redistribution
- Added validate_mcq_option_references() function
- Validation runs during quiz generation to catch LLM errors
- MCQ redistribution now requires --redistribute-mcq flag (opt-in)
- Prevents bug from being reintroduced during answer shuffling
All 445 MCQ questions validated across 35 quiz files.
Add two complementary spell checking tools for content validation:
- check_tikz_spelling.py: Extracts and validates all visible text from
TikZ diagrams including node labels, inline annotations, custom pics,
foreach loops, legends, and comments. Uses pattern-based matching for
common typos with optional aspell integration.
- check_prose_spelling.py: Intelligently parses QMD structure to check
only actual prose content while excluding YAML frontmatter, code blocks,
TikZ diagrams, inline code, math expressions, and URLs. Uses aspell with
comprehensive ignore list of 500+ technical terms and acronyms.
Both tools provide detailed output with file paths, line numbers, and
context for identified spelling errors. The TikZ checker found and enabled
fixing of typos like 'gatewey', 'poihnts', and 'Intellignet' across the
codebase.
GitHub release UI already displays the title, so including it in the
markdown body creates visual redundancy. Updated generator to start
directly with description paragraph followed by Key Highlights section.
All existing releases (v0.1.0 through v0.4.1) have been updated to
follow this cleaner format.
PROBLEM:
- Generator was searching for specific commit messages ('Built site for gh-pages')
- Workflow changed message format to '🚀 Deploy release from commit...'
- This caused it to miss recent October publishes and look back to August
SOLUTION:
- ANY commit to gh-pages branch = publication
- Removed message filtering entirely
- Now uses: git log -n 1 origin/gh-pages (simple and reliable)
RESULT:
- Correctly finds Oct 20, 2025 as last publish (was finding Aug 6)
- Tracks 150 commits since last publish (not 1,491)
- Works regardless of commit message format changes
Replace 'str | None' with 'Optional[str]' in validate_citations.py
for compatibility with Python 3.9 and earlier versions used in
pre-commit environments.
Completely rewrites release notes generation to parse and use actual changelog data:
BEFORE:
- Returned hardcoded generic text regardless of changelog content
- Had misleading fallback that ignored real changes
- No categorization or analysis
AFTER:
- Parses changelog sections (frontmatter, chapters, labs, appendix)
- Categorizes changes (content, infrastructure, bug fixes)
- Extracts specific items with chapter names and details
- Generates statistics from actual data (61 updates, 29 chapters, etc)
- Fails explicitly if changelog missing (no misleading fallbacks)
- Validates output quality (must be > 100 chars)
Release notes now accurately reflect what actually changed rather than
returning generic marketing text. Critical for proper release documentation.
Addresses script organization and maintainability:
- Merged generate_release_notes.py and release_notes.py into changelog-releasenotes.py
- Removed deprecated change_log.py (superseded by changelog-releasenotes.py)
- Added diagram-*.pdf to .gitignore (Quarto auto-generated cache files)
This consolidation simplifies the release workflow and eliminates duplicate code.
Corrects answer redistribution logic in multiple-choice questions to properly update all references to the answer options being swapped, avoiding double-swapping issues.
Addresses an issue where answer text wasn't correctly updated when MCQ answer options were redistributed. It ensures references to option letters (A, B, C, D) are updated in both "The correct answer is X" and "Option X" contexts within the answer text.
Adds beautifulsoup4 and requests libraries to the list of
dependencies needed for the genai scripts. These libraries are
required for enhanced functionality in the scripts.
Implements a script to detect self-referential or circular section
references within Quarto files. This helps identify potential writing
issues where a section refers to itself, its parent, or its child.

- Focus on educational improvements that benefit readers and instructors

Add missing citations to chapter bib files:
- carlini2021extracting to privacy_security.bib
- koomey2011web to frontiers.bib
- quinonero2009dataset to robust_ai.bib
Enhance citation validation script:
- Strip trailing punctuation (.,;:) from citation keys
- Filter out DOI-style citations (e.g., @10.1109/...)
- Prevent false positives from citations like [@key.]
These changes fix all reported citation validation failures while
improving the validation script to handle edge cases better.
Add comprehensive documentation for the new citation validation script
and pre-commit hook, including usage examples, troubleshooting, and
integration details.

files have corresponding entries in their .bib files. This catches
missing bibliography entries before they cause Quarto build failures.
Features:

- Provides clear error messages with missing citation keys
- Only checks files being committed (not entire codebase)
- Runs in quiet mode to reduce noise
New script: tools/scripts/content/validate_citations.py

This fixes the pre-commit hook error where it was looking for files at
/tools/quarto/contents instead of /quarto/contents.
Created check_list_formatting.py to enforce proper markdown list formatting:
- Detects bullet lists without preceding blank lines
- Auto-fixes issues with --fix flag
- Supports --check mode for CI/CD validation

- Comprehensive documentation in README_LIST_FORMATTING.md
This tool ensures markdown renders correctly across all parsers
(Quarto, GitHub, etc.) by requiring empty lines before bullet lists.
