# ms-file-read

Read files before you act on them. Never act on a filename alone.

## Rules

1. Read the file before editing, summarizing, or deciding anything about it.
2. Large files: read in chunks with offset and limit instead of dumping.
3. Verify what you read matches what you expected before building on it.
4. Never read credential material (auth files, tokens, keys). The name is
   warning enough.

## When

- Before any edit: the edit must match what is actually on disk.
- Before answering questions about file contents.
- When a run record, log, or receipt is cited as evidence.
