6-phase lightweight engineering pipeline (Phases 0-5) triggered by '456', 'по 456', 'таска по 456', or 'исправь по 456' for fast-track tasks (everyday bugfixes, small features, or pre-scoped tracks). Slashes token and time overhead by 80-85% compared to Protocol 123 via compact SDD planning, on-demand web research, in-session TDD, single-reviewer risk audit, and deterministic runner scripts/protocol-456.mjs. Pre-scoped tracks skip Phases 1 & 2 directly to Phase 3. Never self-invoke.
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
# The 456 Protocol Skill (v2.0) ## Purpose A lightweight sibling of Protocol 123 with a streamlined 6-phase lifecycle (Phases 0-5) designed for 80% of everyday engineering tasks (bugfixes, targeted features, AST adjustments, or pre-scoped tracks). Slashes token consumption and latency by 80-85% compared to Protocol 123 by eliminating multi-agent debate, removing review-arbiter bureaucracy, bounding web searches to high-quality official sources, and relying on a single specialized domain reviewer. Backed by deterministic runner `scripts/protocol-456.mjs`. ## Precondition & Fast-Track Intake (Phase 0) Protocol 456 handles both general fast-track tasks and pre-scoped plan tracks: 1. **Pre-Scoped Track (Fast-Track Branch)**: If input already names exact target files, step-by-step edits, and a runnable test verification command (e.g. from an SDD remediation spec), Phase 0 verifies the baseline and fast-tracks directly to Phase 3 (In-Session TDD), skipping planning Phases 1 and 2 while strictly retaining Phase 4 (Single-Reviewer Risk Audit). …

How to install
mdr add ivanestar/eitr/protocol-456@sha256:3d716f76de67815fThe line at the top of this page pins the label git:20260906.163e7f1, 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.
