Agent Skills: jq

jq — the command-line JSON processor and its filter language for slicing, filtering, transforming, and reshaping JSON. Use when extracting fields or nested paths from JSON on the command line, filtering/`select`-ing arrays of objects, reshaping or building new JSON objects, emitting CSV/TSV with `@csv`/`@tsv`, getting raw unquoted strings for shell capture with `jq -r`, slurping (`-s`) and aggregating JSON (`add`, `group_by`, averages), parsing API responses, NDJSON pipelines (`-c`), or injecting shell values safely with `--arg`/`--argjson`/`$ENV`. Triggers on mentions of jq, the `jq` command, the jq filter language, `jq -r`, `.foo`/`.[]` filters, `@csv`/`@tsv`, slurp/`fromjson`, or "filter/transform JSON in the terminal". This is the jq CLI and filter language, NOT a generic JSON tutorial and NOT jq language bindings (jaq, gojq, PyPI `jq` — defer those to their own docs).
