paleo AGENTS.md

paleo AGENTS.md is an instructions file for Codex, OpenCode from mocasus/paleo. It costs 300 tokens per session, scanned A, original, MIT.

A collection of instructions for reducing an AI coding agent's text output and context usage while keeping code, commands, and technical terms exact. It includes modes for brief output, context trimming, token budgets, summaries, conversations, and compact JSON.

In plain words
What is it for?
Use it when you want brief responses, a task token budget, trimmed context, compressed conversation summaries, smaller tool-output summaries, or minified structured data.
Why use it?
Long agent responses and accumulated conversation history can use unnecessary context and tokens. These instructions help shorten that material without rewriting code.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Opus 5 $0.00150 $0.00150

Security

Grade A, and why

paleo AGENTS.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

paleo

Token-saving skills for LLM agents. Cut output & context tokens without rewriting code — compress verbosity, keep code, commands, and technical terms byte-exact.

Install (open Agent Skills standard)

npx skills add mocasus/paleo

Installs all 7 skills into every supported agent: Claude Code, Codex, Gemini CLI, Hermes, Cursor, GitHub Copilot, Windsurf, and 40+ clients.

Or clone and copy skills/paleo*/ into your agent's skills directory.

Skills

  • paleo — terse output mode (cut output tokens ~50–70%, code-exact)
  • paleo-trim-context — proactive context trimming before overflow
  • paleo-budget — hard token budget per task, auto-summarize over cap
  • paleo-converse — conversation compression, merge duplicates
  • paleo-summary — shrink bulky tool output to tight intisari
  • paleo-json — compact structured output, minify + collapse
  • paleo-auto — 🆕 zero-touch auto-detection, enables right skills automatically

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
