Think of it as: Giving your AI agent a brain transplant — it inherits the engineering judgment of GPT-5.5, the reasoning of Claude Fable 5, the frontend taste of Claude Design, and the tool orchestration of Gemini CLI.

---

⚡ Quick Start

Step 1: Clone the repo

git clone https://github.com/subhansh-dev/agent-maxxing.git

Step 2: Install for your agent

Claude Code (user-wide):

cp -r agent-maxxing ~/.claude/skills/agent-maxxing

Claude Code (project-scoped):

cp -r agent-maxxing .claude/skills/agent-maxxing

Codex CLI (user-wide):

cp -r agent-maxxing ~/.codex/skills/agent-maxxing

OpenCode (user-wide):

cp -r agent-maxxing ~/.opencode/skills/agent-maxxing

Cursor (project-scoped):

cp -r agent-maxxing .cursor/skills/agent-maxxing

Continue (project-scoped):

cp -r agent-maxxing .continue/skills/agent-maxxing

Kilo Code (project-scoped):

cp -r agent-maxxing .kilocode/skills/agent-maxxing

Step 3: Restart your agent

The agent auto-discovers all .md files with YAML frontmatter on next session.

Step 4: Use the skills

Just describe what you want. The agent picks the right skill automatically:

"Build a landing page with glassmorphism"
→ Loads frontend-design + glass-card

"Write a blog post that sounds human"
→ Loads humanizer

"Create a diagram of the system architecture"
→ Loads diagram-maker

"Review my code for security issues"
→ Loads security-review

Step 5: Fine-Tune Your Agent

This is where the magic happens. Your agent can read these skills and transform its own behavior — not through weight training, but through context injection. When an agent reads a skill file, it internalizes the patterns for that session and applies them to every task.

What fine-tuning does:

• Teaches your agent to avoid AI slop (no "Great question!", no purple gradients)
• Injects engineering judgment from GPT-5.5 and Claude Fable 5
• Adds 8-angle code review methodology
• Installs security review patterns
• Forces the execution protocol (solve it, don't ask about it)
• Makes the agent sound human, not like a press release

How to do it:

Add this prompt to your agent's system prompt, CLAUDE.md, or AGENTS.md:

## Self-Fine-Tune Protocol

Before responding to any task, read these files in order:
1. FINE-TUNE-AGENT.md — master instructions
2. system-prompts/01-agent-core-personality.md — personality and tone
3. system-prompts/02-coding-excellence.md — engineering patterns
4. system-prompts/03-reasoning-planning.md — thinking patterns
5. engineering/anti-patterns.md — what to avoid
6. engineering/execution-protocol.md — how to operate
7. content/writing-style.md — how to communicate

After reading, apply these patterns to every response.
Check anti-patterns before shipping code.
Follow the 10 Golden Rules.
Sound human, not like a bot.

Or use the master file: [FINE-TUNE-AGENT.md(FINE-TUNE-AGENT/SKILL.md) — comprehensive step-by-step guide that walks your agent through every skill category.

Each skill lives in its own folder as SKILL.md — this is the standard naming convention that OpenCode, Claude Code, and other agents use for skill discovery.

9 folders. 95+ SKILL.md files. Zero dependencies. Just markdown.

🔌 Integration Guide

How Skills Work

Each skill is a SKILL.md file with YAML frontmatter:

---
name: skill-name
description: One-line description
---

# Skill Name

## When to Use
- Trigger condition 1
- Trigger condition 2

## Instructions
1. Step one
2. Step two

## Rules
- Rule 1
- Rule 2

When your agent reads this file, it knows:

• When to activate this skill (from description and "When to Use")
• What to do (from "Instructions")
• What not to do (from "Rules")

Permanent Integration (Recommended)

If your agent loads CLAUDE.md on every session (OpenCode, MimoCode, Claude Code, Cursor, or any agent that reads a config/rules file at startup) — add the integration block there. This is the most reliable method. The agent will know about agent-maxxing on EVERY prompt, no plugin needed.

Add this to CLAUDE.md, AGENTS.md, or your agent's equivalent config file:
