Show HN: CostClaw, a local CLI that finds your Claude Code spend leaks

{“telegram”:”CostClaw audits Claude Code logs locally and prices the waste\n\nA Show HN project called CostClaw is a console tool that parses Claude Code session logs in JSONL straight off disk, including the sublogs from subagents and workflows. Parsing happens in memory and nothing leaves the machine; you run it with npx costclaw audit.\n\nThe report hunts four kinds of waste: cache misses (cache reads run $0.30 per million tokens against $3.00 for input), sessions that hammer a single tool a hundred times, short tasks sent to Opus at $15 per million tokens instead of Sonnet’s $3, and long sessions where caching stops paying for itself. It also scores six areas separately, from CLAUDE.md quality to spending discipline.\n\nEvery build seeds the test logs with traps: a fake prompt and a client path. The CLI is free, and costclaw optimize unlocks with a one-time $39 license.”}
