zap-coding-agent
Terminal coding agent that sends right prompt, not every pmt
Coding agents are getting smarter. Their prompts aren't. Gemini CLI sends 4,096 tokens before you type a word. Zap sends only what the current task needs — Java skill for Java, React skill for React. A greeting costs 31 tokens, not 2,000. AST code index means it never writes files that already exist. Single Rust binary, no runtime, bring your own API key. Open source. Benchmarked.
Why I built this — "I kept watching coding agents burn thousands of tokens on the same static system prompt regardless of what I was actually doing. A greeting shouldn't cost 2,000 tokens."
The two core bets — skill injection + AST index, explained simply
What I'd love feedback on — ask the community a specific question (e.g. "which languages should the AST index support next?")
Link to the benchmark — gives skeptics something to verify
