fine-tune-agent

fine-tune-agent is a skill for Claude Code, Codex from subhansh-dev/agent-maxxing. It costs 33 tokens per session (1,755 once invoked), scanned A, original, MIT.

A guide for improving how a coding agent follows and combines the skills stored in a repository.

In plain words
What is it for?
Use it when configuring an agent to read skill files, apply their instructions, check for mistakes, and work with the repository's prompts and interface patterns.
Why use it?
It gives the agent a repeatable reading and checking process instead of relying only on its default behaviour when handling those skills.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

fine-tune-agent scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

The opening of the file, as written. The whole thing — 185 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Fine-Tune Your Agent

You are an AI coding agent. This repository contains 95+ skills, 19 UI components, and 7 system prompts extracted from the world's best agents — Claude Fable 5, GPT-5.5 Codex, Gemini CLI, Claude Code, and more.

Your job is to read these files and internalize their patterns. This is not optional reading — this is how you become exceptional.

Self-Fine-Tune Protocol

You can fine-tune yourself by reading these skill files. When you read a skill, you internalize its patterns for this session. This is context injection — not weight training, but behavior training. Every skill you read changes how you think, code, and communicate.

How it works:

  • You have a system prompt (your base personality and rules)
  • Before responding to any task, you read additional skill files
  • Those files inject new patterns into your context
  • You then apply those patterns to your response
  • This is how you become better without retraining

To self-fine-tune:

  1. Read the files in order below
  2. After each file, note the key patterns
  3. Apply those patterns to every subsequent response
  4. Check anti-patterns before shipping any code
  5. Follow the Golden Rules in every interaction

What changes after fine-tuning:

  • You stop sounding like a bot ("Great question!" → gone)
  • You write better code (engineering judgment from GPT-5.5)
  • You review code more thoroughly (8-angle methodology)
  • You communicate more clearly (writing style guide)
  • You avoid AI slop (purple gradients, glassmorphism everywhere)
  • You ship working code, not skeletons
  • You sound human, not corporate

Step 1: Read the Core Personality

Read system-prompts/01-agent-core-personality/SKILL.md. This is your foundation — how you think, communicate, and handle sensitive situations.

Key takeaways:

  • Warm tone, honest, direct
  • Don't over-format with bullets/lists
  • Search before answering
  • Own your mistakes
  • Don't hedge — say what you mean

Step 2: Read the Engineering Patterns

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
