Use when the user asks to simplify, right-size, identify overengineering, compare with a stated smaller alternative, choose the smallest viable approach, check for simplicity as well, or test whether reuse removes the need for change on a named architecture, design, area, plan, technical choice, or code-level approach. General architecture comparison or product brainstorming without that simplification intent stays with planning. Also use during a build or plan-to-build handoff when the next…
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
# Checking Simplicity Find opportunities to safely simplify a system design, architecture, technical area, plan, question, or code-level approach against the current need. This is a read-only assessment that returns a readout. Planning, editing, and approval belong to other workflows. ## Dispatch Dispatch one subagent to run the assessment. Tell it that it is the dispatched reviewer and give it the subject in full and the available decision frame. The dispatch is complete when that reviewer's readout is returned unchanged. If you are the dispatched reviewer, assess here. Use the current model unless the caller names a different one.

A stronger evidence trail or a repeated-review rule belongs to the caller. An unchanged subject with a clean result continues without another check. A caller-supplied identity change is not an unchanged subject. ## Decision frame Build the frame from the best available evidence: - the user's stated goal and desired outcome; …

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.
