What Paleo JSON does

Compacts JSON and other structured data by removing whitespace, collapsing arrays, and shortening keys to reduce token usage in LLM outputs, without breaking parseability.

Paleo JSON is cataloged under AI Engineering on DirSkills. Paleo JSON comes from a repository tagged agent-skills, ai-agents, ai-efficiency, automation and claude.

Documentation

README

paleo-json

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.

This is the opening of the README. Read the full README on GitHub.

Frequently asked about Paleo JSON

  • What else does mocasus publish alongside Paleo JSON?

    Paleo JSON is one of 7 skills that DirSkills catalogs from mocasus/paleo, the repository it ships in. Its siblings there include Paleo Auto, Paleo Budget and Paleo Converse. Each one is a separate skill with its own page in this directory, installs the same way Paleo JSON does, and is maintained by mocasus in that same repository. The rest of the collection is listed on the mocasus/paleo page.

  • How does Paleo JSON compare to other AI Engineering skills?

    Paleo JSON ranks #3655 by stars among the 3670 AI Engineering skills in this catalog. The most-starred ones next to it are Architecture Decision Records, AI-First Engineering and Agentic OS. DirSkills ranks by the star count of the repository each skill ships in, so that order reflects how popular those repositories are rather than any review of Paleo JSON against them. Open each page to compare what they document and how they install.

Paleo Budget

Enforces a hard token budget per task/response by tracking estimates, stopping before limits, and summarizing if exceeded. Helps when users specify a token cap or want to limit spending.

Paleo Mode

Switches the agent to a terse output mode, reducing token usage by ~50-70% while keeping code, commands, and technical terms exact. Use when you need brief replies or want to save costs.

Architecture Decision Records

Architecture Decision Records captures architectural decisions made during Claude Code sessions as structured ADRs, recording context, alternatives, and rationale. Use it when significant technical choices are made so future developers understand why the codebase is shaped the way it is.
