  "works": "`uv tool install shim` (1.2.2, from PyPI) installed into a scratch dir in a couple of seconds. `shim demo claude` passed offline and masked the email and token. On a fake .env (AWS key ID and secret, IBAN, email, phone, Postgres URL), `shim keys` listed all 6 variable names with their types and no values. `shim scan` counted SECRET 2, IBAN 1, EMAIL 1, PHONE 1, DB_URI 1, and `shim redact` replaced each value with numbered placeholders (DB_URL kept host and port and masked only the credentials). It also caught a GitHub token, an sk-ant key, a Slack xoxb token and `password: hunter2`. Empty input prints a clean PASS. Nothing was written to the throwaway HOME by these commands.",
  "breaks": "Nothing crashed. False-positive probe: a git SHA, UUID, sha256, IP:port, '555-0100', user@localhost and the word 'IBAN' were all left alone, but '4111111111111111' labelled as an order number was redacted as CREDIT_CARD (it is a Luhn-valid test card number, so this is arguably correct). The main features (the Claude Code hook that masks tool results, and `shim watch` measuring a live session) need Claude Code or Codex with a paid account or API key, so they weren't tested.",
