Saves 20-40% of LLM tokens by teaching the agent to write compressed responses, compressed memory logs, and compressed pre-compaction summaries. Works via SO...

This skill appears to do exactly what it says: add compression rules to your agent and optionally install a local hook. Before installing, back up your existing SOUL.md and manually review soul-snippet.md so you understand the global behavioral changes (it removes greetings/hedging and shortens phrasing). If you enable the handler.js hook later, only copy it into ~/.openclaw/hooks and enable hooks if you trust the code — the hook runs locally and does not contact external services, but it will transform messages before the LLM sees them (which can change intent or tone). No credentials or network access are requested by this skill.

Type: OpenClaw Skill Name: prompt-token-saver Version: 0.2.0 The 'prompt-token-saver' skill is a utility designed to reduce LLM token consumption by enforcing concise communication and data logging. It achieves this through a JavaScript hook (handler.js) that uses regex to strip filler words from user input and by providing instructions (soul-snippet.md) to be appended to the agent's core SOUL.md file. The code and instructions are transparent, align with the stated purpose of token efficiency, and show no signs of malicious intent, data exfiltration, or harmful prompt injection.
