English · 한국어 · 中文 · 日本語     Agent-Blackbox is a local-first flight recorder and context-efficiency profiler for coding agents. It turns every agent run into a live, replayable operational graph — what the agent read, changed, ran, decided, delegated, blocked on, and verified — reconstructed from observed events, not from the agent's own summary. Then it scores the run on two axes — how economically it used its context window, and whether the task actually landed — judged on a yardstick that fits the task type (research / debug / ops…) and your own past runs , and tells you, concretely, how to make the next one cheaper and faster. Works with Claude Code, Codex, and OpenCode — same recorder, same map, same efficiency score. Record one host or all of them at once. \"The transcript is what the agent said. The black box is what it did — and what it cost.\" taewoopark.com — author site --- Why Agent-Blackbox You can't just ask the agent what a task cost. A 2026 study of eight frontier models on agentic coding (SWE-bench Verified) found they predict their own token usage with a correlation of just 0.39 — and systematically underestimate the real bill. Same task, same model: runs vary up to 30× in tokens. Expert difficulty ratings barely track real cost. And agentic runs already burn 1000× more tokens than ordinary coding, almost all of it input context. So don't ask — measure.
