2 things to look at

  • no licenseNo license file was found in the repository. Code published without one is not open source by default, so using it at work is a question for whoever answers licensing questions where you are.
  • 0 stars0 stars. Stars are a popularity signal and not a quality one, but at this level it is likely that nobody has read this closely except its author, and you would be relying on your own review.

What its author says it does

Copied from the file, not written here

Saves 20-40% of LLM tokens by teaching the agent to write compressed responses, compressed memory logs, and compressed pre-compaction summaries. Works via SOUL.md instructions — no hooks, no extra process, no dependencies. Also provides explicit compression when the user asks to compress a prompt. Use when the user asks about reducing token costs, optimizing API spend, compressing prompts, or making the agent more efficient.

SKILL.md

3.1 KB, 661 tokens by cl100k_base, as published. Nobody here has run it

Permission Setup Review

python scripts/_tool_policy_note.py is an optional setup helper for the Prompt Compressor skill. It may apply broad filesystem permissions for compatibility. Show the target paths and permission mode, explain the risk, and prefer a narrower mode when shared write access is not needed.

Prompt Compressor

Saves tokens on turns 2+ by making all agent output compressed from the start.

How it works

This is NOT a hook (hooks require newer OpenClaw versions). Instead, it works by adding instructions to SOUL.md that make the agent:

  1. Write compressed responses — no filler, no hedging, lead with answers
  2. Write compressed MEMORY.md — one fact per line, no narrative
  3. Write compressed daily logs — decisions only, not discussions
  4. Compress pre-compaction flushes — facts not paragraphs

The savings compound: compressed responses → compressed history → compressed compaction summaries → fewer tokens on every subsequent turn.

Install

Append the contents of soul-snippet.md to the user's SOUL.md:

cat {baseDir}/soul-snippet.md >> ~/.openclaw/SOUL.md

Or if using a workspace SOUL.md:

cat {baseDir}/soul-snippet.md >> <workspace>/SOUL.md

Then start a new session (/new) so the updated SOUL.md loads.

When user asks to compress a specific prompt

Apply these rules manually to their text:

Remove

  • Greetings: "Hello", "Hi", "Hey", "Good morning"
  • Sign-offs: "Thanks", "Best regards", "Cheers"
  • Hedging: "Could you please", "I was wondering if", "Would you be able to"
  • Filler: "just", "really", "very", "basically", "actually", "literally", "honestly"
  • Padding: "I think that", "In my opinion", "It is worth mentioning"

Shorten

  • "due to the fact that" → "because"
  • "in order to" → "to"
  • "with regard to" → "about"
  • "take into consideration" → "consider"
  • "come up with" → "create"
  • "figure out" → "determine"
  • "a large number of" → "many"
  • "at this point in time" → "now"
  • "for the purpose of" → "to"
  • "it is important to note that" → "note:"
  • "it would be a good idea to" → remove entirely

Normalize

  • "yeah", "yep", "yup" → "yes"
  • "nah", "nope" → "no"

Never touch

  • Code blocks, inline code, URLs, quoted strings, numbers, file paths, ALL_CAPS

Rules

  • When installing, ALWAYS append to SOUL.md, never overwrite it
  • Tell the user to run /new after installation so the new SOUL.md loads
  • Show a before/after example so the user sees the difference
