Harden a skill or any agent instruction file (CLAUDE.md, AGENTS.md, GEMINI.md, .cursor/rules, .github/copilot-instructions.md) through judge-panel refinement rounds until it clears a 3-tier promotion gate, then promote it. A quality gate that runs after authoring, not an authoring tool. TRIGGER when the user types /skill-forge, asks to test/harden/forge/prove a skill or an instruction file, wants a CLAUDE.md or AGENTS.md driven through adversarial rounds before shipping, asks 'is this skill…
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
# Skill-forge - judge-panel skill-hardening harness A lead (the Forge Master) chairs ephemeral runner teammates that exercise a draft document via prompt-injection, and a persistent judge panel that scores the transcripts. The lead amends one thing per round and applies a strict 3-tier promotion gate, until the document promotes or hits a budget ceiling. It is proven by forging itself. The target is a `SKILL.md` by default, but the same loop hardens **any agent instruction file** - `CLAUDE.md`, `AGENTS.md`, `GEMINI.md`, `.cursor/rules/*`, `.github/copilot-instructions.md` - because those files have the same failure surface as a skill: they steer an agent and can mislead it. The artifact type is detected deterministically and drives three adaptations (the lens set, the runner variant, and the canonical intent); see [Artifact type and the lens-selector](#artifact-type-and-the-lens-selector) below. ## Boundary …

How to install
mdr add bjcoombs/ai-native-toolkit/skill-forge@sha256:aedb359c016e0c7bThe line at the top of this page pins the label git:20261007.747a8f8, 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.
