Troubleshoot and resolve common issues with the ClickHouse Node.js client (@clickhouse/client). Use this skill whenever a user reports errors, unexpected behavior, or configuration questions involving the Node.js client specifically — including socket hang-up errors, Keep-Alive problems, stream handling issues, data type mismatches, read-only user restrictions, proxy/TLS setup problems, or long-running query timeouts. Trigger even when the user hasn't precisely named the issue; vague symptoms like "my inserts keep failing" or "connection drops randomly" in a Node.js context are strong signals to use this skill. Do NOT use for browser/Web client issues.

How matches are found. Word for word: the exact same text. Edited: shares passages with this file (“99% same” means 99% of its five-word phrases also appear here; 10% or more counts). Their own version: similar meaning, or, weakest, the same name. We can’t tell which project had it first. Projects are counted among the 200 most-starred candidates, and mentions are links to the repository we found, up to 50 per site, so both counts are a floor.

ClickHouse Node.js Client Troubleshooting
Reference: https://clickhouse.com/docs/integrations/javascript
⚠️ Node.js runtime only. This skill covers the
@clickhouse/clientpackage running in a Node.js runtime exclusively — including Next.js Node runtime API routes, React Server Components, Server Actions, and standard Node.js processes. Do not apply this skill to browser client components, Web Workers, Next.js Edge runtime, Cloudflare Workers, or any usage of@clickhouse/client-web. For browser/edge environments, the correct package is@clickhouse/client-web.
How to Use This Skill
- Identify the issue — match symptoms to the Issue Index below and read the corresponding reference file.
- Lead with the diagnosis — explain what's likely causing the issue before giving the fix.
- Note version constraints — flag if a fix requires a minimum client version and check it against what the user provided.
- Ask only what's missing — if the fix is version-dependent and you don't know their version, ask; otherwise help immediately.

Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
Now do this for your own.
Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
