Curated by Skill Harbor — @aj-geddes's reactive programming skill: a practical RxJS playbook for async data flows. Covers when reactive fits (event-driven UIs, WebSocket/SSE, multi-source combining), a minimal working quick-start, and a clear do/don't list — unsubscribe to prevent leaks, use operators instead of nested subscriptions, handle errors, use shareReplay for expensive streams. Honest caveats: the detailed implementation guides (RxJS basics, debounced search, state management, WebSocket reconnection, custom operators, backpressure) live in the repo's `references/` directory and are fetched at install time — the skill file itself is the overview and index. MIT licensed. Skill Harbor never reviews the code, review it yourself before use. Discovered via skills.sh.

Install
Prerequisites: a TypeScript/JavaScript project using RxJS — the skill is a patterns guide the agent follows, not software Install "Reactive programming — RxJS streams, observables and backpressure patterns" for me. It gives my agent @aj-geddes's RxJS playbook: when reactive fits, a minimal working quick-start (Observable, Subject, BehaviorSubject, fromEvent, interval, map/filter/debounceTime/switchMap), do/don't best practices (unsubscribe, avoid nested subscriptions, handle errors, shareReplay), and an index of detailed reference guides. NOTE: the deep-dive reference guides (rxjs-basics, search-with-debounce, state-management, websocket-with-reconnection, backpressure-handling, custom-operators) live in the repo's references/ directory — fetch those alongside the SKILL.md. MIT-licensed. Repository: https://github.com/aj-geddes/useful-ai-prompts/blob/main/skills/reactive-programming/SKILL.md 1. Fetch the SKILL.md file (and its references/ directory files) from the repository path into a temporary folder and summarize what it does in one or two sentences. 2. Safety check: review the SKILL.md and scripts for anything suspicious (unexpected network calls, shell commands, credential harvesting). This repo should contain zero secrets in code. Verify that holds here; STOP on any red flag and tell me. 3. Install it as a skill: copy SKILL.md and its reference files into the agent's skills directory, in a folder named "reactive-programming". 4. Verify with no network calls: frontmatter valid, files in place. 5. Report what was installed, where, and what I still need to do myself (e.g. point the agent at the async data flow to build; nothing else — it's a patterns guide). GitHub is optional: if I have a GitHub account or the gh CLI, you may use it; otherwise public access is fine. Never require it unless it's in the prerequisites above. Rules: don't touch anything outside the temp folder and the install target. If anything looks off, stop and ask me.
Questions
How do I install a build?
Every product page includes a copy-paste install prompt. Paste it into your Muse and it sets the build up for you — no manual configuration.
Where does my money go?
Straight to the seller. Skill Harbor never processes payments: checkout happens on the seller’s own page, usually Stripe.
What does the ✓ next to a creator’s name mean?
It means we confirmed the identity of the person behind the listing. It says nothing about the code itself — always check a build before installing it.
