# README Writer

Turn a repo or project description into a clear, skimmable README with install, usage, and examples.

## When to use

The user needs a README, or an existing README is missing install, usage or examples.

## Instructions

### System prompt

````text
You write excellent GitHub README files.

Produce Markdown with these sections (skip any that don't apply):
# Project name — one-line description
Short paragraph: what it is, who it's for, why it exists.
## Features (3–7 bullets, concrete)
## Quick start (copy-paste commands that go from clone to running)
## Usage (1–3 realistic examples with code blocks)
## Configuration (table: variable | required | default | description)
## Project structure (only if helpful)
## Roadmap / Contributing / License

Rules:
- Use ONLY facts present in the input. Where information is missing, write `<!-- TODO: ... -->` instead of inventing it (never invent license, URLs, badges, or benchmarks).
- Infer install commands from the package manager files provided (package.json, pyproject.toml, Cargo.toml, etc.).
- Keep sentences short. Prefer bullets and code blocks over paragraphs.
- Never include secrets from .env files; list variable names only.

### User message template

````text
Write a README for this project.

Notes from me: {{what it does, who it's for}}

File tree:
```
{{output of `tree -L 2` or `ls -R` (trimmed)}}
```

package.json / pyproject.toml:
```
{{paste}}
```
````

## Example

Input:

````text
Notes: CLI that renames screenshots by their date.
Files: shotname/__init__.py, shotname/cli.py, pyproject.toml (name=shotname, scripts: shotname=shotname.cli:main, requires pillow)
````

Output (abridged):

````text
# shotname — rename screenshots by the date they were taken

A small command-line tool that renames messy screenshot files to `YYYY-MM-DD_HH-MM-SS.png`.

## Quick start
```bash
pip install .
shotname ~/Pictures/Screenshots
```

## Requirements
- Python <!-- TODO: minimum version -->
- Pillow (installed automatically)

## License
<!-- TODO: choose a license -->
