data-tools-skill

AI agent skill for structured data manipulation. Teaches agents when and how to use dedicated tools instead of fragile text processing (grep/sed/awk) on structured formats.

Tools Covered

Tool	Format	Use Case
jq	JSON	Query, filter, transform JSON data
yq	YAML	Edit CI configs, docker-compose, K8s manifests
dasel	JSON/YAML/TOML/XML	Universal selector, format conversion
qsv	CSV/TSV	Fast data exploration, filtering, analysis

Core Principle

**Never use `grep`, `sed`, or `awk` on JSON, YAML, TOML, XML, or CSV data.** These tools treat structured data as flat text and break on multi-line values, nested structures, quoted strings, and encoding differences.
