yq: YAML Query and Extraction Tool

Always invoke yq skill to extract YAML fields - do not execute bash commands directly.

Use yq to extract specific fields from YAML files without reading entire file contents, saving 80-95% context usage.

When to Use yq

Use yq when:

• Need specific field(s) from structured YAML file
• File is large (>50 lines) and only need subset of data
• Querying nested structures in YAML
• Filtering/transforming YAML data
• Working with docker-compose.yml, GitHub Actions workflows, K8s configs

Just use Read when:

• File is small (<50 lines)
• Need to understand overall structure
• Making edits (need full context anyway)
