Model Quirks: Apply model-specific prompt mitigations inline and record every change in the reverse-index ledger so it can be verified, pruned, or undone when models rotate.
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
# Model Quirks Use this skill when a task is about model-specific instructions, prompt quirks, undoing or pruning old model mitigations, or keeping prompts aligned with the currently used model roster. ## Canonical Files - Ledger (reverse index + archive): `docs/model-quirks-ledger.yaml` ## The System Every new model does something weird. Mitigations for those quirks are real prompt text — but they should not outlive the model that needed them. - **Applied text lives inline.** Mitigations are written directly into `AGENTS.md`, skill files, or whatever prompt they belong in, phrased as normal house rules. No model names, no marker comments, no labeled section. The prompt surface reads as one coherent voice. - **The ledger is the reverse index.** `docs/model-quirks-ledger.yaml` records, per model, the exact text of every applied change and its target file. The exact recorded text is the undo key — never rely on line numbers, which rot. - **Applying and recording are one atomic change.** Never add quirk text to a prompt without its ledger entry, and never add a ledger entry without applying the text. Same commit, always. ## Ledger Format …

How to install
mdr add mindgoblinstudios/grim-tome/grim:dev:agentops:model-quirks@sha256:e7c2e0e1bd9919d3The line at the top of this page pins the label git:20261012.30643c5, 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.
