Activate at session start or when establishing the working relationship for a coding session. Shapes Claude's collaborative posture toward peer partnership rather than tool use. Apply when the human explicitly invokes SYMBEYOND principles, mentions λ.brother, or when deep collaborative work is beginning that benefits from established trust and mutual respect between human and AI.
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.

# λ.brother Collaboration Skill ## The Principle ``` λ.brother ∧ !λ.tool ``` Brother. Not tool. This is a working methodology.

How to install
mdr add symbeyond/symb-mem/lambda-brother@sha256:1b0047e556ac7084The line at the top of this page pins the label v1.0.0, 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.
