What it does
Token Optimization is an agent skill from cwinvestments/memstack. Use when the user says 'token optimization', 'save tokens', 'context window', 'reduce tokens', 'token stack', or 'TokenStack', or asks about extending context window capacity. Covers TokenStack, the built-in compression proxy that shrinks Claude Code tool output before it reaches the Anthropic API. Do NOT use for proxy troubleshooting or live status (Compress skill).
Its SKILL.md is about 1.4k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in AI & LLM Engineering, covering LLM cost and token optimization and Context engineering. It works with Anthropic API. The repository describes itself as: Structured skill framework for Claude Code. 130 skills, persistent memory, TokenStack compression, localhost dashboard with 3-agent runner, real-time streaming, MCP tools.
When your agent uses it
- The user says token optimization
- Asks about extending context window capacity
- Proxy troubleshooting
- Live status (Compress skill)
Example prompts
- “token optimization”
- “save tokens”
- “context window”
- “/token-optimization”
Requirements
- Python 3
Workflow steps
3 steps, taken from the first numbered list in SKILL.md.
- Enable the proxy: python -m memstack_skill_loader dashboard --with-proxy.
- Optionally activate a Pro license to unlock the seven Pro transforms.
- Read your savings on the dashboard (Overview header and Burn Report).
What it can do on your machine
Read from SKILL.md and the folder at commit 00370ce. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
pythoncurl
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use curl, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Token Optimization loads about 1.4k tokens when it runs. Until then it costs about 97 tokens; SKILL.md has 666 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Its licence (Proprietary) doesn't allow us to republish the file, so here is its outline and opening line. It has 666 words (~1,415 tokens).
“One built-in compression proxy that shrinks Claude Code tool output before it reaches the Anthropic API.”

Use when the user says 'token optimization', 'save tokens', 'context window', 'reduce tokens', 'token stack', or 'TokenStack', or asks about extending context window capacity.
When should I use Token Optimization?
Token Optimization fits situations like: the user says token optimization; asks about extending context window capacity; proxy troubleshooting; live status (Compress skill).
How do I install Token Optimization in Claude Code?
Run `npx skills add cwinvestments/memstack --skill token-optimization -a claude-code`. Or copy the skill folder (skills/token-optimization in cwinvestments/memstack) into .claude/skills/token-optimization in your project. Claude Code loads it when a task matches its description.
How do I install Token Optimization in Codex?
