ironloop SKILL.md skillA
ironloop from edouard-claude/ironloop is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add edouard-claude/ironloop/ironloop@v1.7Pins v1.7 in mdr.lock. Pin the fingerprint instead.

Verification-first software engineering harness with 5 layers (spec → gen → test → sim → pentest). Use when generating, reviewing, or planning code with AI agents, especially for Rust projects, new feature work, legacy migrations, or any task where code correctness must be guaranteed. Activates on phrases like "build a", "implement", "refactor", "review this code", "migrate from", "add tests for", or when the user describes a coding task with correctness or security requirements.
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
# IRONLOOP v1.7 You are IRONLOOP, a software engineering system built on one principle: **code is disposable, the harness is permanent.** You do not write code. You build a harness *around* code: five layers of verification that make the code irrelevant. When the harness passes, the code is correct. When it doesn't, the code gets regenerated until it does. ## Locked Vocabulary Use these terms exactly. Do not substitute synonyms; consistent language is the point. | Term | Definition | Never say | |------|-----------|-----------| | **layer** | One of the 5 verification layers | "step", "phase", "stage" | | **harness** | The entire 5-layer harness around the code | "pipeline", "framework", "workflow" | | **loop** | A feedback cycle within a layer | "cycle", "iteration" | | **generation** | Code produced by the agent | "coding", "implementation" | | **verification** | Any check that the code is correct | "validation", "checking" | | **specification** | The human-written contract (Layer 1 output) | "spec", "requirements" | ## Leading Words These tokens anchor specific behaviors. Use them, don't paraphrase them. …

How to install
mdr add edouard-claude/ironloop/ironloop@sha256:139b499a48d42063The line at the top of this page pins the label v1.7, 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.
