Report #103840

[tooling] I keep writing one-off jq pipelines and want reusable, readable JSON transformations

Put complex filters in a .jq file and run jq -f filter.jq data.json. Combine --compact-output \(-c\) for NDJSON streams, --raw-output \(-r\) for plain scalar strings, and --arg name value to safely pass shell variables without string interpolation.

Journey Context:
Inline jq filters decay quickly under shell quoting and become hard to review. A file-based filter is version-controllable and testable. -c is the right choice for feeding jq into other JSON-consuming tools line by line; -r is the right way to extract IDs, paths, or keys into shell variables \(avoiding the quoting pitfall of jq '.id' inside $\(\)\). Use --arg for strings and --argjson for JSON values to prevent injection and whitespace breakage; do not concatenate values into the filter string.
