Main-side verification checks — pre-commit test / sensitive-file blocking, discipline conformance, novel-trap detection. Pure verify-and-flag; persistence of findings is scribe's job, intent-artifact match is witness's.
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
# Guard — Main-Side Verification Checks Automatic verification layer running in the main session (System 1). No agent spawn. Guard covers **verification** checks that main can reliably do on itself: sensitive files, test execution, discipline conformance, and detection of novel traps during work. Guard is pure verify-and-flag — it detects, it warns, it blocks. It does **not** record, accumulate, or persist findings; those belong to scribe (post-work persistence). It also does **not** verify whether the artifact matches the user's intent; that check is structurally unreliable when done inside the agent that produced the artifact, and is delegated to [witness](../../agents/sonmat-witness.md). **Scope boundaries**: | Check kind | Owner | Why | |---|---|---| | Test execution, sensitive file blocking, discipline conformance, novel-trap detection | **guard** | Real-time verification during work; synchronous check-and-block at decision points | …

How to install
mdr add jun0-ds/sonmat/guard@sha256:a8f06b7a6f147e63The line at the top of this page pins the label git:20260928.900ac85, 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.
