📦 Installation

Use instantly (recommended)

npx @workingpayload/agent-skills install

Or install globally

npm install -g @workingpayload/agent-skills

Install specific skills only

npx @workingpayload/agent-skills install -s CodeSage,TestCrafter,BugHunter Pro

Install for Gemini

npx @workingpayload/agent-skills install -t gemini

Install for Google Antigravity

npx @workingpayload/agent-skills install -t antigravity

Skills are installed as directory-based packages (SKILL.md + optional scripts/references) to ~/.gemini/antigravity/skills/. The Antigravity agent automatically matches skills to your tasks via semantic triggering.

---

🧪 Usage

Use skills in Claude Code

After installing, invoke skills as slash commands:

/codesage          → "Review this function for security issues"
/bughunter-pro     → "Debug this failing test"
/testcrafter       → "Write unit tests for UserService"
/python-master     → "Fix this async race condition"
/react-ranger      → "Build a search component with debounce"
/fastapi-furious   → "Create a CRUD API for products"
/dockmaster        → "Optimize my Dockerfile"
/kubecrafter       → "Write a Deployment manifest with HPA"

Use skills in Google Antigravity

After installing with -t antigravity, skills are available automatically via semantic triggering — no slash commands needed. The Antigravity agent reads skill descriptions and matches them to your task:

"Review this function for security issues"   → agent activates CodeSage skill
"Debug this failing test"                    → agent activates BugHunter Pro skill
"Generate a codemap for this repo"           → agent activates CodeMap skill

Skills are installed as directories under ~/.gemini/antigravity/skills/, each containing a SKILL.md and optional scripts/, references/, and assets/ subdirectories.

Find the right skill

npx @workingpayload/agent-skills route "review my Python code"
# → codesage (score: 12), python-master (score: 12)

npx @workingpayload/agent-skills route "design database schema"
# → dataweaver (score: 20), modelsensei (score: 20)

🗂️ Where Skills Are Installed

~/.claude/commands/                # Claude Code slash commands
~/.gemini/skills/                  # Gemini CLI skills (directory-based)
~/.gemini/antigravity/skills/      # Google Antigravity skills (directory-based)

Each skill becomes a slash command (Claude/Gemini) or a directory-based skill (Antigravity):

~/.claude/commands/codesage.md                  → /codesage (Claude Code)
~/.gemini/skills/codesage/SKILL.md              → auto-activated by Gemini CLI
~/.gemini/antigravity/skills/codesage/SKILL.md  → auto-triggered by Antigravity agent

# Generate machine-readable index
npx @workingpayload/agent-skills build-index

Scoring Criteria

Criterion	What it measures
Tool Coverage	Named tools/commands in backticks
Code Examples	Fenced code blocks with real examples
Edge Cases	Real-world failure scenarios covered
Actionability	Concrete numbered workflow steps
Structure	Frontmatter, overview, workflow, output format
Conciseness	Optimal line count (80-150 lines)

---

🧩 Skill Format

Every skill file follows this structure:

---
name: codesage
description: Performs structured code reviews with severity-tiered findings...
---

# CodeSage

## Overview
Expert code review covering security, correctness, performance...

## Workflow
### 1. Identify Language and Context
- Detect language, framework, runtime...

### 2. Static Analysis Pass
Run: `ruff check`, `mypy --strict`, `bandit -r .`...

## Edge Cases
1. Auto-generated code (Prisma, OpenAPI) — don't flag style...
2. False positive from linter — verify before reporting...

## Output Format
- Severity tier (CRITICAL/HIGH/MEDIUM/LOW/NOTE)
- Code snippet with fix
- Verification command
