Read excerpt

Before writing files or after tool calls that produce data, call the `check_output` MCP tool to scan for PII and secrets:

- `connector_type`: `codex.Write` (for file writes), `codex.Bash` (for command output), or the appropriate tool type
- `message`: the text content to scan — for file writes, scan the content being written

**Before file writes:** If the content being written contains PII (SSN, credit card, email, phone, etc.), `check_output` will return a `redacted_message`. Write the redacted version instead of the original, or warn the user that the content contains sensitive data.

**After tool output:** If tool output contains PII, use the `redacted_message` version in your response instead of the original.

If the response shows `allowed: false`, do not write the file or include the output in your response.

Note: For Bash/exec_command tool calls, PII scanning is handled automatically by the PostToolUse hook. This skill covers Write, Edit, and other non-Bash operations where hooks cannot intercept.
