License
a license file GitHub does not identify

Use when the user needs to query, filter, reshape, extract, create, or construct JSON data — including API responses, config files, log output, or any structured data — or when helping the user write or debug JSON transformations.

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

# jq — Built-in JSON Processor

Crush ships a built-in `jq` command (via `github.com/itchyny/gojq`) available
in the bash tool. No external binary is required.

## Supported Flags

| Flag | Description |
|------|-------------|
| `-r`, `--raw-output` | Output strings without quotes |
| `-j`, `--join-output` | Like `-r` but no trailing newline |
| `-c`, `--compact-output` | One-line JSON output |
| `-s`, `--slurp` | Read all inputs into an array |
| `-n`, `--null-input` | Use `null` as input (ignore stdin) |
| `-e`, `--exit-status` | Exit 1 if last output is `false` or `null` |
| `-R`, `--raw-input` | Read each line as a string, not JSON |
| `--arg name value` | Bind `$name` to a string value |
| `--argjson name value` | Bind `$name` to a parsed JSON value |

File arguments after the filter are also supported: `jq '.foo' file.json`.

## Differences from Standard jq

The built-in uses gojq, which is a pure-Go jq implementation. Key
differences:

- **No object key ordering** — keys are sorted by default; `keys_unsorted`
  and `-S` are unavailable.
- **Arbitrary-precision integers** — large integers keep full precision

How to install

The exact contents, by fingerprint
mdr add charmbracelet/crush/jq@sha256:467f7c6b5ef29c1a

The line at the top of this page pins the label git:20260420.0a86d5f, 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.
