Most agents forget everything between sessions. This is the opposite: a self-evolving memory built with Claude Code and a Karpathy-style architecture — why standard RAG fails agents, how a compile-time knowledge graph beats query-time retrieval, and the loop that makes knowledge compound.
Every utility that translates tool-calling formats between LLM providers — LiteLLM, Bifrost, Portkey, claude-code-router, Vercel AI SDK, first-party /anthropic endpoints — what each one actually does, and the three failure classes none of them have solved. Plus the conclusion I arrived at: stop adapting context downward to each model, and build a harness that orchestrates harnesses instead.
A token-efficiency reading of the 'harness > model' thesis: the same model solved 6.7% of tasks bare vs 68% with the right harness — at 4× fewer tokens. What a harness is, why it's where the token bill actually lives, and what the Life-Harness and Meta-Harness papers prove. Plus how your Claude Code stack (subagents, skills, hooks, graphs) already is a harness.
My ready-to-use graphify setup for Claude Code: a knowledge graph instead of full-repo reads, semantic extraction on cheap OpenRouter (deepseek) instead of Claude tokens, auto-watch via hooks, protection against leaking secrets into the graph. All packaged in the claude-code-token-savers repository.
How to assemble a working [email protected] mailbox in one evening with no mail server at all: receive mail through free Cloudflare Email Routing forwarded to Gmail, send through the Resend API on top of Amazon SES, and as a bonus — Claude Code that emails you over the API. Inside: why receiving and sending don't conflict, real Cloudflare and Resend API calls, and the gotchas I hit.
A small utility and global /cctoggle slash command that switches off all Claude Code plugins and user-scope MCP servers at once — clearing their tool definitions out of context — and restores exactly what it disabled. No app restart. Inside: apply semantics, selective disable, backups, and limitations.
How OpenClaude replaces per-provider wrapper commands (Clother, shell aliases) with a single ~/.openclaude/settings.json config — all models, all providers, one CLI.
How to use jolehuit/clother to switch Claude Code between Z.AI, Kimi, MiniMax, OpenRouter, Alibaba, Ollama, LM Studio and custom providers via clother-* commands — without rewriting ~/.claude or global env vars.
Working approaches to saving tokens in Claude Code and Opus 4.7/4.8: subagents, skills, hooks, Chinese models, knowledge graphs, RAG, xhigh effort, session management, summarization on a cheap model, input compression (headroom, pxpipe, mcp-compressor), and server-side savings (Tool Search, context editing, prompt caching, Batches API). A checklist to cut costs by 10x.
