87% Cost Savings & Sub-3s Latency: I built a "Warm-Cache" harness for persistent Claude agents.

The "Goldfish Problem" is Expensive. I Decided to Fix the Plumbing.

Most Claude implementations leave 90% of their money on the table because they don’t optimize for Prompt Caching. I’ve been running a personal agent in my Discord for months that manages my AWS infra and codebases, and I finally open-sourced the harness, which I’ve named Galadriel after my main personal assistant.

The Stats

  • Cost: $10 for every $100 you’d normally spend (Tested against OpenClaw/Cursor workflows).
  • Speed: 85% drop in latency. 100K token context goes from 11s to <3s.
  • Memory: Integrated MemPalace for permanent, vector-based recall that doesn't break the cache.

The Technical Stack

  • 3-Tier Stacked Caching: Separate breakpoints for Tool Definitions, System Prompts (CLAUDE.md), and Trailing History.
  • Privacy: Built for private subnets. No middleman, no message caps—just your API key and your rules.
  • Ethics: Baked-in KarpathyCLAUDE.md)guidelines to kill "agent bloat."

If you’re tired of paying the "Context Tax" just to have an agent that remembers who you are, here you go. It is customized for Discord for my specific needs, but the core logic ensures Galadriel runs like an absolute dream: she never forgets, maintains strict engineering principles, and optimizes every cycle.

Your feedback is most welcome!
