paleo-json

SkillAI & models

Use when user says "compact json", "minify output", "tight structured", or the agent must emit JSON / structured data. Strip insignificant whitespace, collapse long arrays, shorten keys where safe, keep it parseable. Cuts tokens on structured payloads. Off: "pretty print" / "human-readable".

Compact structured output. JSON / YAML / tables → minimal tokens, still valid.

Rules

  • Minify: remove whitespace between tokens (valid JSON stays parseable).
  • Collapse arrays of repeated shapes into a count + 1 example when the consumer allows.
  • Keep keys verbatim unless a documented short alias exists — never invent keys.
  • Preserve: values, types, order where it matters, escaping.
  • YAML: drop comments, shorten, keep indentation minimal but valid.
  • Numbers/booleans/null: never reformat in ways that change type.

Levels

  • lite: minify whitespace only (safest).
  • full (default): minify + collapse repetitive array tails.
  • ultra: minify + alias keys per a provided map.

Switch

  • paleo-json / compact json / minify on. pretty print off.

Gotchas

  • Always return valid, parseable output — a broken payload costs more than the tokens saved.
  • Don't alias keys unless the consumer expects them; default = keep keys.
  • Streaming/chunked JSON: minify only after the full object is known.
