Guided token optimization for AI agent workspaces. Triggers on phrases like "save tokens", "optimize tokens", "context window too large", "memory files too big", "scan my workspace", "trim workspace", "find token waste", "再扫一下", "帮我省 Token", "优化 Token 使用", "上下文太长了", "内存文件太大", "还有哪里可以优化". Also handles brutal-mode toggle: "enable brutal mode", "disable brutal mode", "开启狂暴模式", "关闭狂暴模式". On first use walks the user step-by-step through workspace cleanup; supports on-demand re-scans at any time.…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Token Saver (token-slim) - **Author**: Evan Song · [github.com/Songhonglei](https://github.com/Songhonglei) - **Repository**: https://github.com/Songhonglei/better-agent-skills - **License**: MIT Helps AI agents and their users reduce token consumption by auditing workspace files, identifying bloat, and guiding targeted cleanup. ## Core Concept Every project-context file (memory index, agent config, heartbeat, etc.) is injected into **every single session**. Keeping them lean = direct, compounding savings. The goal is a three-tier memory layout: ``` memory index ← always loaded, < 150 lines — pointers + essentials only memoryres/*.md ← loaded on demand — reference tables, specs, backlogs memory/YYYY-MM-DD.md ← raw daily log — rarely loaded ``` For full strategy details: see `references/strategies.md` --- ## Mode Routing After matching a mode, **first `read` the corresponding reference file**, then follow that flow. Do not rely on memory. | User intent | Mode | Must read first | |---|---|---| | First-time setup / "save tokens" | **Mode A** | `references/mode-a-onboarding.md` | …

How to install
mdr add songhonglei/better-agent-skills/token-slim@sha256:28bddbc0a0ec9cd3The line at the top of this page pins the label git:20260620.71f0028, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
