Use when the user needs help configuring Crush — writing crushrc (the Bash config format) or crush.json, setting up providers, models, LSPs, MCP servers, hooks, skills, permissions, or changing Crush behavior.
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
# Crush Configuration Crush supports two config formats: - **`crushrc`** — a Bash script that builds config by calling Crush builtins. **Preferred.** Because it is real Bash you get includes, secrets, conditionals, and variables for free. - **`crush.json`** — static JSON. Fully supported; see [Legacy JSON format](#legacy-json-format). Both are discovered together and deep-merged. Priority (highest to lowest): 1. `.crushrc` / `crushrc` / `.crush.json` / `crush.json` (project-local, closer-to-cwd wins; Windows uses `.\.crushrc` / `.\crushrc`) 2. `$XDG_CONFIG_HOME/crush/crushrc` or `~/.config/crush/crushrc` (`%XDG_CONFIG_HOME%\crush\crushrc` or `%USERPROFILE%\.config\crush\crushrc` on Windows) Data directories (`~/.local/share/crush` and `%LOCALAPPDATA%\crush`) contain machine-owned JSON state only; Crush does not discover or execute a `crushrc` from those locations. If a directory has both `crushrc` and `crush.json`, they merge (`crushrc` wins on conflicts) and Crush logs a warning. ## crushrc at a glance A `crushrc` is a plain Bash script executed at load time with the same embedded shell the `bash` tool uses. It builds config by calling builtins (`provider`, …

How to install
mdr add charmbracelet/crush/crush-config@sha256:08c98b02b235cff0The line at the top of this page pins the label git:20261029.a2c8a95, 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.
