Why Skillry

Most Claude Code resource repos are link lists (you still copy files by hand) or are Claude-only. Skillry is different on five axes:

	Skillry	Typical "awesome" list	Typical CLI installer
Installs actual skill/agent files (not links)	✅	❌	✅
Multi-platform (Claude + Codex + Copilot + Gemini)	✅	❌	❌ (Claude only)
Per-agent permission boundaries (least-privilege tools)	✅	❌	⚠️
Validation harness (structure + frontmatter lint + permission + lockfiles)	✅	❌	⚠️
Skill-sync: discover (license + risk scan), normalize (frontmatter + provenance), vet (staged, attributed, never auto-enabled)	✅	❌	❌
Native plugin marketplace (sha-pinned, reproducible)	✅	❌	⚠️
Full upstream attribution for redistributed content	✅	n/a	⚠️

These directly reflect Anthropic's own guidance: least-privilege tools, single-responsibility subagents, and auditing third-party skills before use.

Quickstart

Claude Code (native plugin marketplace — recommended)

# In Claude Code:
/plugin marketplace add FluxonLab/Skillry
/plugin install core-operations@skillry

Browse all departments with /plugin marketplace after adding.

npm / npx (any platform, no clone, no publish needed)

# Runs straight from GitHub — no global install, no npm account required:
npx github:FluxonLab/Skillry install                                  # dry-run, all platforms
npx github:FluxonLab/Skillry install --apply --targets claude         # or: codex copilot antigravity
npx github:FluxonLab/Skillry install --apply --targets claude --community   # include attributed 3rd-party skills

# Or install the CLI globally:
npm install -g skillry
skillry install --apply --targets claude codex
skillry validate

Portable installer (from a clone)

git clone https://github.com/FluxonLab/Skillry
cd Skillry
python3 tools/install.py            # dry-run: shows what will be installed
python3 tools/install.py --apply --targets claude          # or: codex copilot antigravity

The installer rewrites machine-specific paths to your $HOME and backs up any existing config (*.bak-skillry) before writing. Dry-run is the default. Verify with python3 tools/validate.py.

What's inside

• 125 original skills across 18 departments — concrete procedures, real commands, checklists, and safety rules (not generic templates); median ~150 lines of substance.
• 73 original subagents with explicit tools allowlists and read-only vs. write scopes.
• A curated community/ set — 98 skills + 49 agents from 6 permissively-licensed sources, redistributed with full attribution (MIT/ISC only — see NOTICE and THIRD-PARTY-NOTICES).
• A flagship CLAUDE.md — a project-agnostic engineering operating manual (inspect-first, surgical changes, security, i18n + theme parity, dev-launch defaults, honest verification). It governs this repo and is written to be copied into your own project as a strong default: cp CLAUDE.md /path/to/your/repo/CLAUDE.md.
