v0.1.0

First release.

whatbroke diffs two recorded runs of an AI agent and reports what actually changed: dropped tool calls, drifted arguments, new errors, output flips, latency and cost regressions. Deterministic, offline, no API keys.

• whatbroke diff before.jsonl after.jsonl with terminal, --json and --md reports
• CI-friendly exit codes via --fail-on breaking|warning|never
• Recorder SDK that wraps OpenAI and Anthropic clients in one line
• Plain JSONL trace format you can write from any language
• Bundled example: a support agent before and after a cheap model swap, including the part where it quietly stops cancelling subscriptions
