What does Claude Code look like when you ask it to audit a codebase without editing anything?
A captured `claude --print` session against the demo app, prompted to audit five production-readiness concerns and produce a structured report without modifying any code. Claude used 11 tool calls (1 Glob, 4 Grep, 6 Read), zero edits, finished in 54 seconds, cost 46 cents, and produced a 5-section report with file:line references. The article shows the verbatim audit output, the tool-call census, and a head-to-head comparison against `grep`/`rg` shell scripts for each of the five concerns: TODO scans and missing-test detection are commodity work the agent overpays for, but flagging `new Date()` calls that bypass an injection pattern (vs benign date arithmetic) and reading the dead-letter queue line as 'operational risk' are the kind of semantic judgment that justifies the cost.
