Read the full description
Coding agents rewrite code you never asked them to touch, and the tests still pass. Sonah reads the agent’s Claude Code or Codex session along with the code, then shows on one page: whether each ask was done, what the agent decided on its own, which of its claims its own results contradict, and what is wrong in the code. Every quote is checked word for word. Runs locally through your own Claude login. No account, no telemetry. Free for individuals.

Yes Parsing Claude Code and Codex session logs alongside diffs and using an LLM to check claims against results is a mostly LLM-driven analysis and report UI.
