Report #8872

[tooling] Processing multiple JSON files or injecting shell variables into jq breaks on quotes or types

Use \`jq --slurp '.\[0\] \* .\[1\]' file1 file2\` to merge arrays, or \`jq --argjson id "$ID" 'select$.id == $id$'\` for typed variables

Journey Context:
Agents often attempt shell interpolation like \`jq '.name == \\"$var\\"'\`, which fails when \`$var\` contains quotes or is meant to be a number/boolean. \`--arg\` passes strings safely, but \`--argjson\` parses the value as JSON, preserving types $numbers, booleans, null$. For multiple files, \`--slurp\` reads the entire input stream into an array, enabling operations like merging $\`add\`$, diffing, or cross-referencing without shell loops that break streaming and handle errors poorly.
