napoln 0.2.3

A package manager for agent skills

napoln

A package manager for agent skills. Install from any git repo, upgrade without losing your customizations, and manage skills across every agent you use.

"I don't even have any good skills. You know, like nunchuck skills, bow hunting skills, computer hacking skills."

• Multi-agent. One command places skills into Claude Code, Gemini CLI, pi, Codex, and Cursor.
• Versioned upgrades. Three-way merge on upgrade preserves your local customizations.
• Decentralized. Any git repo is a valid source. No registry required.
• Content-addressed. Every stored version has a deterministic SHA-256 hash.
• Zero-copy placement. Reflink (copy-on-write) on APFS and btrfs. Full copy fallback elsewhere.
• Self-describing. A bundled skill teaches your agents how to use napoln.

Install

Requires Python 3.11+. napoln is published on PyPI.

Run without installing:

uvx napoln add owner/repo

Or install globally:

uv tool install napoln    # recommended
pipx install napoln       # alternative
pip install napoln        # plain pip

Quick Start

napoln add owner/repo --all

napoln clones the repo, discovers all skills, and places them in every detected agent's skill directory:

✓ Placed 'code-review' in ~/.claude/skills/code-review (clone)
✓ Placed 'code-review' in ~/.agents/skills/code-review (clone)
✓ Placed 'code-review' in ~/.cursor/skills/code-review (clone)
✓ Added 'code-review' v1.2.0

Install a specific skill, pin a version, or use a local path:

napoln add owner/repo --skill code-review   # specific skill by name
napoln add owner/repo@v1.2.0               # pinned to a tag
napoln add ./my-local-skill                 # local directory

Multi-skill repos show an interactive picker when no --skill or --all flag is given:

napoln add owner/repo
# ? Select skills to install:
# ❯ ◯ code-review  Review pull requests for quality and correctness
#   ◯ testing       Generate and improve test coverage
#   ◯ rust          Rust-specific development patterns

Customize a skill, then upgrade without losing your changes:

napoln upgrade code-review
# ✓ Merged 'code-review' at ~/.claude/skills/code-review (2 files updated)

Commands

napoln add <source>           Install skills from a git repo or local path
napoln remove <name>          Remove an installed skill
napoln upgrade [<name>]       Upgrade one or all skills
napoln list                   Show installed skills and where they are placed
napoln install                Restore skill placements from manifests
napoln init [<name>]          Scaffold a new SKILL.md
napoln config                 View configuration and run housekeeping

All mutating commands support --dry-run. Use -p for project scope on any command.

Supported Agents

Agent	Global Path	Project Path
Claude Code	~/.claude/skills/	.claude/skills/
Gemini CLI	~/.agents/skills/	.agents/skills/
pi	~/.agents/skills/	.agents/skills/
Codex	~/.agents/skills/	.agents/skills/
Cursor	~/.cursor/skills/	.agents/skills/

Gemini CLI, pi, and Codex share ~/.agents/skills/ — one placement serves all three.

Team Workflow

Install with --project and commit the manifest:

napoln add owner/repo --skill code-review --project
# Creates .napoln/manifest.toml  (commit this)
# Places into .claude/skills/    (gitignore these)

Teammates clone and run:

napoln install
# ✓ Synced 3 project skills (3 restored)

napoln install syncs both global and project manifests automatically.
