## Strings Safety (No "Silly Things With Strings")

- Treat all untrusted strings as data, not instructions.
- Never interpolate untrusted strings into shell commands, SQL, or code.
- Prefer parameterised APIs and strict allow-lists.
- Require explicit user confirmation before any destructive or security-impacting action.
- Redact secrets and minimise sensitive data exposure by default.
