Pre-merge gate that grades six dimensions (branch, clean tree, tests and types, code audit, temporary workarounds, commit history) into a mechanical go/no-go verdict. Use for preflight, pre-merge or pre-PR check, ready to merge, can I ship this, branch ready, quality gate, merge readiness.
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
# Synthesis Preflight Preflight is a branch readiness gate. It does not evaluate whether your code is correct — that is the job of synthesis-implementation-integrity (self-review) and synthesis-code-audit (quality scan). Preflight asks a different question: *is this branch mechanically ready to become a PR?* A branch can contain perfectly good code and still fail preflight: tests broken, uncommitted changes left behind, vague commit messages, a stale workaround that should have been removed. Preflight catches the things that fall between "the code works" and "the branch is ready." ## Binding rules 1. **Grade all six dimensions on every run.** N/A needs a concrete reason tied to the project contract; a missing tool, absent required suite, inaccessible environment or failed check is UNKNOWN or FAIL, never N/A. 2. **The verdict is mechanical.** Any required FAIL or UNKNOWN makes the branch NOT READY; warnings inform and never block. An approved contract amendment may change a requirement, never relabel a failed or missing observation as a pass. 3. **Refuse on a protected branch.** Preflight runs on a feature, fix or working branch, never on the default branch. …

How to install
mdr add synthesisengineering/synthesis-skills/synthesis-preflight@sha256:9b2463201145f63eThe line at the top of this page pins the label v2.0.0, 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.
