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
# Reasoning Layer — Design Notes This folder contains buddy's guard-mode reasoning layer: a light port of [slimemold](https://github.com/justinstimatze/slimemold) that gives buddy the ability to notice structural patterns in a coding conversation — load-bearing assumptions, unchallenged chains, grounded premises — and surface them in character through the pet personality. This document explains the design decisions the code itself doesn't obviously justify. Read it before changing algorithms, prompts, or thresholds. ## Core principle: sycophancy as a tool Guard mode is built on a deliberate inversion of LLM sycophancy. Sycophancy works on users because warmth feels validating. It's a failure mode because the warmth isn't tied to truth — "great question!" validates no matter what the question was. Guard mode takes the same linguistic warmth and points it at structural reasoning facts. The pet is warm (that's buddy's default state, carried by the species voice + NEVER constraints ported from effigy-lite) and in guard mode that warmth lands on concrete observations about the reasoning graph: - "That 'we need auth' assumption is holding up three things — worth …

How to install
mdr add fiorastudio/buddy/src/lib/reasoning/DESIGN.md@sha256:9b5395ac91e6d7a4The line at the top of this page pins the label git:20260622.3979f4b, 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.
