v1.2.3

What changed

• aligned python-skills with the newer repo standards used in the more recent skill bundles
• added canonical root documentation in README.md and checklist-style planning in ROADMAP.md
• added maintainer docs under docs/maintainers/ and repo-local validation tooling in pyproject.toml, scripts/validate_repo_metadata.py, .github/scripts/validate_repo_docs.sh, and tests/test_validate_repo_metadata.py
• normalized all four active skills' SKILL.md and agents/openai.yaml files to better match shipped behavior
• retired duplicate per-skill README.md files in favor of references/customization.md
• updated shipped shell entrypoints toward Zsh-safe execution while preserving the newer layered customization behavior now on main

Breaking changes

• per-skill README.md files were removed as maintained public surfaces; canonical per-skill docs now live in SKILL.md, agents/openai.yaml, and references/

Migration/upgrade notes

• update any maintainer workflows that still read per-skill README.md files to use SKILL.md and references/customization.md instead
• use uv sync --dev, uv run python scripts/validate_repo_metadata.py, zsh .github/scripts/validate_repo_docs.sh, and uv run pytest as the repo's current maintainer validation path

Verification performed

• uv run python scripts/validate_repo_metadata.py
• zsh .github/scripts/validate_repo_docs.sh
• uv run pytest
• help-path smoke checks for each shipped shell entrypoint
