React composition pattern for domain features (screens, panels, tools, editors, wizards). Trigger when designing, reviewing, or refactoring a domain-level React component, particularly when a leaf takes flag props like `disabled`, `loading`, `isSubmitting`, `canX`, `submitting`; when JSX has inline ternaries gating UI on state; when platform variance (`.tsx` / `.web.tsx`) is in play; when a hook returns multiple flags being relayed into one leaf; or when the user mentions "chassis", "zone…
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
# Zone Composer Zone Composer is a design pattern for constructing **domain-level components** (screens, panels, tools, editors, wizards, and other surfaces a feature owns). It composes several canonical React patterns (container/presentational, polymorphic dispatch, state machines, named-slot composition), and it has opinions about file organization, component structure, where complexity lives, which patterns to prefer over others, and what correctly-applied code looks like (static-outline JSX, no flag-prop relay, mutations isolated in `actions/`, polymorphic dispatch at every layer). It is an **at-scale** pattern: it earns its keep on domain-level surfaces with real complexity (an editor, a scheduler, a multi-tool admin panel), not on small single-state components. Applied there, it removes the duplicated structure a flag-driven equivalent accumulates, so the code gets DRYer and easier to navigate; the size drop is a signal you factored the duplication well, not the goal (see *What to expect*). …

How to install
mdr add simiancraft/simiancraft-skills/zone-composer@sha256:dfa700d7b22438e3The line at the top of this page pins the label git:20260603.6277101, 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.
