Jq Json Processor

**Judgement:** A strong, practical jq reference skill focused on real-world JSON processing from the command line. It is best suited for users who already work in a shell environment and need quick, accurate jq patterns for filtering, transforming, and inspecting JSON. **What it does well:** - Provides concrete examples for common jq operations: field extraction, array processing, mapping/filtering, grouping, and reduction. - Demonstrates typical API and file-based workflows (curl | jq, reading/writing JSON files, merging files). - Highlights important jq options like `-r`, `-c`, and `-S` that are critical for correct output formatting in scripts. - Points to authoritative external resources (jq manual and jqplay) for deeper exploration and experimentation. **Risks / Limitations:** - jq’s syntax has a learning curve; the examples are helpful but do not fully explain the underlying semantics, so beginners may still struggle with complex queries. - Several examples modify files via shell redirection (`> file.tmp && mv`); careless use can overwrite important data if paths or commands are incorrect. - The skill assumes a UNIX-like shell with jq installed; it is less directly applicable in environments without a standard terminal or where jq is unavailable. **Recommended scenarios:** - Scripting and DevOps workflows that involve querying or transforming JSON from APIs, config files, or log pipelines. - Quickly crafting or adjusting jq filters during debugging sessions (e.g., inspecting new API responses). - Data preparation steps in CI/CD pipelines or ad-hoc command-line data munging where JSON is the primary format. - Teaching or onboarding technically inclined users to jq by using concrete, copy-paste-ready examples from this skill.
