# @j4flmao/agent-skills
641 agent skills for software development — planning, architecture, low-level, backend, frontend, desktop, mobile, devops, management, enterprise, product, ml, ai, security, data, data-science, design, quality, blockchain, prompt-engineering, cloud-native, system-design, site-reliability-engineering, game. Each skill is a `SKILL.md` defining triggers, rules, and response format.
> **Looking for guardrails, not just knowledge?**
> This repo is a free library of skills. If you want rules managed as one
> system across Claude Code, Cursor, Codex CLI, Gemini CLI, OpenCode, Copilot
> and Windsurf, plus safety hooks and an eval kit, see
> [Agent Discipline Pro](https://buy.polar.sh/polar_cl_kCJAUXacBrFJfYhxZCMqYXLmhNCvA0ao7RYKC4HTsuI).
## Installation
### Option 1: Use in the repo directly (no install needed)
Agent config files are already in this repo. Open this project in your agent and it works immediately:
```bash
git clone https://github.com/j4flmao/agent-skills
cd agent-skills
# Open your agent here — configs are ready
```
| Agent | Auto-loaded files |
|-------|-------------------|
| Claude Code | `.claude/CLAUDE.md` + `.claude/rules/` + `.claude/skills/` + `.claude/hooks/` + `.claude/settings.json` |
| OpenCode | `.opencode/AGENTS.md` + `.opencode/commands/*.md` |
| Amp | `.amp/AGENTS.md` + `.amp/agent-skills.md` + `.amp/subagents.md` |
| GitHub Copilot | `.github/copilot-instructions.md` |
| Gemini | `.gemini/INSTRUCTIONS.md` |
| Cursor | `.cursor/rules/agent-skills.mdc` + `.cursor/rules/compression.mdc` |
| Codex CLI | `.codex/AGENTS.md` + `.codex/rules/` + `.codex/hooks/` + `.codex/skills/` |
| Windsurf | `.windsurf/rules/*.md` |
### Option 2: Copy skills into another project
Clone once, then copy the agent config folder into any project:
```bash
# Clone skills repo somewhere on your machine
git clone https://github.com/j4flmao/agent-skills ~/skills
# Copy the config for your agent into your project
cp -r ~/skills/.claude /path/to/your/project/ # Claude Code
cp -r ~/skills/.opencode /path/to/your/project/ # OpenCode
cp -r ~/skills/.cursor /path/to/your/project/ # Cursor
cp -r ~/skills/.amp /path/to/your/project/ # Amp
cp -r ~/skills/.codex /path/to/your/project/ # Codex CLI
cp -r ~/skills/.windsurf /path/to/your/project/ # Windsurf
```
Or cherry-pick individual skills:
```bash
# Copy only the skills you need
cp -r ~/skills/skills/backend/dotnet /path/to/project/skills/
cp -r ~/skills/skills/devops/docker-patterns /path/to/project/skills/
```
### Option 3: npx skills add (after pushing to GitHub)
```bash
# Requires the repo to be pushed to GitHub
npx skills add j4flmao/agent-skills # all 641 skills
npx skills add j4flmao/agent-skills --bundle backend-only
npx skills add j4flmao/agent-skills -g # global (every project)
```
## Bundles
```bash
npx skills add j4flmao/agent-skills --bundle <name>
```

## How Skills Work
1. User makes a request
2. Agent matches trigger keywords in `skills/**/SKILL.md`
3. Agent reads the matched SKILL.md + reference files
4. Agent responds following that skill's Response Format
No need to remember skill names. Just describe the problem.
### Examples
```
User: "write a brief for a chat app" → create-brief
User: "design the order database schema" → backend-database-patterns
User: "review this PR for security issues" → code-review
User: "set up Docker for this project" → docker-patterns
User: "build an iOS order list screen" → ios
```
No keyword match? Agent routes through `master-orchestrator`, detects the project stack, and picks the right skill.

Mobile universal skills apply across all platforms: patterns, testing, performance, security, networking, storage, deployment, push-notifications, in-app-purchase, crash-reporting, deep-linking, offline-first, biometrics, map-location, camera-media, analytics, widgets, localization.
Enterprise skills cover compliance, governance, identity, integration, legacy migration, multi-tenancy, SLA management, high availability (replica + load balancer + version sync + data migration), business continuity (BCP/DR, vendor risk, ransomware playbook), and capacity planning (forecasting + procurement). Product skills cover analytics, growth, onboarding, pricing, research, and feature prioritization.

## Output Compression
Every skill enforces: **No filler. No preamble/postamble. Why use many token when few do trick.**
Agent config files contain the compression rules:
- `.claude/rules/compression.md`
- `.opencode/AGENTS.md`
- `.amp/AGENTS.md`
- `.cursor/rules/compression.mdc`
- `.github/copilot-instructions.md`
- `.gemini/INSTRUCTIONS.md`
- `.codex/rules/compression.md`
- `.windsurf/rules/compression.md`
