git clone --recurse-submodules https://github.com/LeoLin990405/claude-code-skills.git
cd claude-code-skills && ./install.sh

./install.sh productivity    # Only productivity skills

./install.sh --canonical-only

This keeps category toolkit routers and canonical skills, but skips legacy compatibility wrappers such as all-plan, provider-specific CCB shims, and pm-* aliases.

See GOVERNANCE.md for the packaging policy behind bundled skills, submodules, compatibility wrappers, and source-repo retirement.

git clone --recurse-submodules https://github.com/LeoLin990405/claude-code-skills.git
ln -s "$PWD/claude-code-skills/productivity/obsidian-cli" ~/.claude/skills/obsidian-cli

Counts below match ./install.sh --canonical-only --list: category toolkit routers are included when present, legacy compatibility wrappers are excluded, and external nested submodule packs are not flattened into the default install surface.

Category roots also expose toolkit router SKILL.md files migrated from the former claude-skills umbrella repo:

• ai-collaboration/ -> coordination toolkit
• productivity/ -> knowledge toolkit
• development/ -> developer toolkit
• documents/ -> document toolkit
• design/ -> design toolkit
• product-management/ -> PM toolkit

Compatibility wrappers are still kept in-repo for legacy installs. If you want the smallest canonical install surface, use ./install.sh --canonical-only.

All skills derived from Lenny's Podcast -- 86 actionable PM skills:

These external packs are kept as upstream submodules, but they do not expose root-level SKILL.md files at the paths below. install.sh therefore does not flatten them into the default skill install surface.

9 upstream repositories are linked as submodules. Some expose root-level skills that install.sh can link directly; others are nested upstream packs that remain available in-tree without being flattened into the default install surface.

# Update all submodules
git submodule update --remote --merge

# Clone with submodules
git clone --recurse-submodules https://github.com/LeoLin990405/claude-code-skills.git

Submodule governance updates in this repository:

• productivity/obsidian-cli is vendored to remove a self-owned submodule dependency
• documents/mineru remains a self-owned submodule because it still has a standalone release surface: CLI script, examples, changelog, and contributing guide
• development/r-analytics remains a self-owned submodule because it is still treated as an independent canonical repo
• development/github-repo-design is vendored to remove a self-owned submodule dependency
• research/aris was removed from the catalog after its source repository was archived

The longer-lived decision rules now live in GOVERNANCE.md.

See CONTRIBUTING.md for details on adding skills, reporting bugs, and submitting PRs.
