state-management from darknecrocities/skillbuilder is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add darknecrocities/skillbuilder/state-management@git:20261029.162f89bPins git:20261029.162f89b in mdr.lock. Pin the fingerprint instead.

Declarative state machines, TanStack Query server-state caching, invalidation, optimistic updates, atomic Zustand slices, and signals.
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
# Declarative State Machines, Cache & Signals (`/state-management`) > **Philosophy**: *Server state is an asynchronous remote cache; client state is an ephemeral synchronous state machine. Never store remote data in local UI state. Prohibit boolean explosion. Invalidate with Query Key Factories. Memoize store selectors to eliminate re-render cascades.* This skill establishes production architecture for state management across **TanStack Query (React Query)**, **Zustand**, **Jotai**, **XState**, and **Signals**. --- ## 1. Quick Navigation & Progressive Disclosure | Resource Type | Document | Description | | :--- | :--- | :--- | | **Reference** | [references/tanstack-query-caching-patterns.md](references/tanstack-query-caching-patterns.md) | Query key factories, stale time configurations, targeted cache invalidation. | | **Reference** | [references/zustand-atomic-slices.md](references/zustand-atomic-slices.md) | Slice composition patterns, selector memoization to prevent re-renders. | | **Utility** | [scripts/verify_state_hygiene.py](scripts/verify_state_hygiene.py) | Scans components for boolean flag explosions, un-memoized store selections, and inline query keys. | --- …

How to install
mdr add darknecrocities/skillbuilder/state-management@sha256:bacfeb86b2439972The line at the top of this page pins the label git:20261029.162f89b, 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.
