Use to REPLACE part of an existing brownfield system incrementally — behind a routing facade, one slice at a time, verified by contract equivalence against a green safety net — rather than restructuring it in place. Loaded internally by brownfield-refactorer when the human chooses replacement over Mikado in-place restructuring.
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
# Strangler Fig Method Replaces a component by growing a new implementation alongside the old one, behind a facade that routes traffic, slice by slice, until the old implementation has no callers left and can be deleted. Unlike Mikado (restructure what exists), this method REPLACES it — appropriate when the existing code is too coupled to restructure safely, or when the target is a different stack/design entirely. **Precondition.** Same as Mikado: a green safety net (`characterize-with-contracts` / `brownfield-harness-builder`) must exist first. Here the safety net does double duty — it is replayed against BOTH the old and the new implementation; a slice only cuts over when the new implementation is contract-equivalent to the old one on every test in the harness. ## Procedure ### 1. Establish the facade Introduce (or confirm an existing) routing seam in front of the component being replaced — a gateway route, a feature-flagged branch, or a proxy layer — such that traffic can be switched per-slice between OLD and NEW without touching callers. If no seam exists, this is the first prerequisite: build the facade itself as slice zero, verified by the harness against the OLD …

How to install
mdr add sebastiendegodez/skraft-plugin/strangler-fig-method@sha256:376b0ed8b451693aThe line at the top of this page pins the label git:20260806.b506b65, 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.
