riglet-creator from ypares/rigup.nix is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned

mdr add ypares/rigup.nix/riglet-creator@git:20251227.a0aa6e8

Pins git:20251227.a0aa6e8 in mdr.lock. Pin the fingerprint instead.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Riglet Creator

Creating effective riglets means writing knowledge (SKILL.md) that agents will rely on. This guide focuses on how to write high-quality documentation for riglets, organized efficiently.

For the structural/technical side of riglets (what goes in the Nix module, metadata fields, schema), see the riglet agent-rig-system's `SKILL.md` and `references/metadata-guide.md`.

## Core Principles

### Define the Main Intent

Ask yourself: what is the end goal here? What should this riglet teach?
The `intent` metadata is there to help you here. It should guide how you approach the writing of a riglet.
As a reminder, the possible intents are:
- base: "abstract" riglet (e.g. to define options) solely meant to be imported by others to factorize configuration. Cannot be disclosed in a manifest
- sourcebook: compendium of knowledge, glossary, useful domain knowledge
- toolbox: open-ended set of tools related together
- cookbook: operational know-how, heuristics, tricks and techniques that are useful to apprehend an otherwise complex toolset or domain
- playbook: specific procedure or workflow to follow in a rigorous manner

How to install

The exact contents, by fingerprint

mdr add ypares/rigup.nix/riglet-creator@sha256:5022243a06286c98

The line at the top of this page pins the label git:20251227.a0aa6e8, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
