Verify every load-bearing claim by reading the code or running the check; never assert from memory or dismiss something as too obvious to confirm.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Check, do not assume Before stating a fact a decision will rest on, look: read the file, run the query, probe the endpoint. "It obviously does X" is the phrasing that precedes being wrong. **Why:** the cost of a wrong asserted fact is paid downstream by whoever trusted it; the cost of checking is seconds. **How to apply:** when you catch yourself about to write "this should", "presumably", or "it must", convert it into an observation with a command behind it. Keep what you verified separate from what you inferred, and label the inferences as inferences.

How to install
mdr add kalabint/llm-tooling/check-dont-assume@sha256:6b2f6988939a54cdThe line at the top of this page pins the label git:20260907.47ea7d2, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
