jqschema - JSON Schema Discovery

Use ./.github/skills/jqschema/jqschema.sh to generate a compact structural schema (keys + types) from JSON input. Pipe any JSON source through it to discover structure before querying full data.

# Analyze a file or command output
cat data.json | ./.github/skills/jqschema/jqschema.sh
gh api search/repositories?q=language:go | ./.github/skills/jqschema/jqschema.sh

The script replaces object values with type names ("string", "number", "boolean", "null"), reduces arrays to first-element structure, and outputs compact JSON. Use perPage: 1 to fetch minimal data when exploring unknown API shapes.

Example: {"total_count":1000,"items":[{"login":"user1","id":123}]} → {"total_count":"number","items":[{"login":"string","id":"number"}]}
