LLM streaming response handler — production SSE streaming UIs with cancellation and error recovery

Prerequisites: a frontend/backend project that calls an LLM streaming API (OpenAI, Anthropic, or similar) — the skill is an implementation guide the agent follows, not software Install "LLM streaming response handler — production SSE streaming UIs with cancellation and error recovery" for me. It gives my agent @curiositech's streaming guide: choose SSE for one-way LLM streaming, implement token-by-token display (never buffer before display), add AbortController cancellation, error states with retry, cleanup on unmount to avoid memory leaks, typing indicators, and use the copy-ready patterns — basic SSE stream handler, React useStreaming hook, Next.js edge-runtime API route — then run the 12-point production checklist (rate limiting, token tracking, streaming fallback, accessibility, mobile targets, network recovery, max length, cost estimation). MIT-licensed. Repository: https://github.com/curiositech/some_claude_skills/blob/HEAD/.claude/skills/llm-streaming-response-handler/SKILL.md 1. Fetch the SKILL.md file (and any helper 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 helper files into the agent's skills directory, in a folder named "llm-streaming-response-handler". 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. wire the useStreaming hook or SSE handler into my chat UI and API route; nothing else — it's a methodology). 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.
