# Book SFT Pipeline

A standalone example skill for training language models to write in any author's style. It is not published as a separate Claude Code marketplace plugin from this repository.

## Installation

### Claude Code / Cursor / Codex

Agent Skills hosts expect a directory containing `SKILL.md`, not a flat copied markdown file. From the repository root, copy the whole example directory into the target skill root:

```bash
# Claude Code project-scoped install
mkdir -p .claude/skills
cp -R examples/book-sft-pipeline .claude/skills/book-sft-pipeline

# Cursor project-scoped install
mkdir -p .cursor/skills
cp -R examples/book-sft-pipeline .cursor/skills/book-sft-pipeline

# Codex / OpenAI Agent Skills install
mkdir -p .agents/skills
cp -R examples/book-sft-pipeline .agents/skills/book-sft-pipeline
```

### Manual

Reference the `examples/book-sft-pipeline/SKILL.md` file directly only if your agent does not support the Agent Skills directory layout.
