feynrules-validator SKILL.md skillA
feynrules-validator from rise-agi/magnus is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add rise-agi/magnus/feynrules-validator@git:20260315.85ba619Pins git:20260315.85ba619 in mdr.lock. Pin the fingerprint instead.

Validate FeynRules .fr model files for physical consistency using Mathematica via Magnus cloud. Triggers when the user wants to check a .fr model file for Hermiticity, diagonal mass/quadratic terms, and kinetic term normalization.
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
# FeynRules Validator ## Overview This skill validates FeynRules `.fr` model files for physical consistency by running four standard checks in both Feynman and Unitary gauge (8 checks total) using remote Mathematica execution via the Magnus cloud platform. Validation is a critical step between writing a `.fr` model and generating a UFO model — it catches errors in the Lagrangian before they propagate to event generation. ## Workflow ### Step 1: Prepare the Model Ensure the `.fr` file is complete and saved to disk. Know the exact Lagrangian symbol name (e.g., `LSnew`, `Lag`, `LBSM`). ### Step 2: Run Validation Execute the `validate-feynrules` blueprint using `magnus run` (see magnus skill): ```bash magnus run validate-feynrules -- --model path/to/model.fr --lagrangian LSnew ``` **Parameters**: | Parameter | Required | Description | |-----------|----------|-------------| | `--model` | Yes | Path to the `.fr` model file | | `--lagrangian` | Yes | Exact Lagrangian variable name defined in the `.fr` file | The `.fr` file is automatically uploaded via the FileSecret mechanism. ### Step 3: Interpret Results …

How to install
mdr add rise-agi/magnus/feynrules-validator@sha256:0b167d0c2a085cc7The line at the top of this page pins the label git:20260315.85ba619, 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.
