node-26 SKILL.md skillA
node-26 from usetemi/skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add usetemi/skills/node-26@git:20260514.be2ce6bPins git:20260514.be2ce6b in mdr.lock. Pin the fingerprint instead.

Use when upgrading, validating, or modernizing Node.js projects for Node.js 26, or when answering implementation questions about Node.js 26 features and compatibility. Covers Temporal enabled by default, V8 14.6 Map/WeakMap get-or-insert helpers, Iterator.concat, Undici 8, raw crypto key formats, removed/deprecated APIs, native addon rebuilds, platform minimums, and release/LTS readiness decisions.
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
# Node 26
Practical workflow for adopting Node.js 26 in real projects. Prefer official
Node.js release notes and API docs for date-sensitive details because the v26
Current line can change quickly.
For API patterns, examples, and migration details, read
`references/node-26-upgrade-guide.md`.
## Upgrade Workflow
1. Establish the target.
- Check `node --version`, `node -p "process.versions"`, package manager
version, CI images, Dockerfiles, `.nvmrc`, `.node-version`, `mise`,
Volta, and `package.json` `engines`.
- Treat Node.js 26 as Current until it reaches LTS. For production services
already on an LTS line, recommend waiting for the LTS handoff unless the
user explicitly wants Current or needs a v26 feature.
2. Scan compatibility before changing code.
- Search for removed or risky APIs:
```bash
rg -n "_stream_(readable|writable|duplex|transform|passthrough|wrap)|writeHeader\\(|--experimental-transform-types|module\\.register\\(|\\blocalStorage\\b" .
```
- Search for native addon or prebuild risk:
```bash

How to install
mdr add usetemi/skills/node-26@sha256:3a41e5ddada74817The line at the top of this page pins the label git:20260514.be2ce6b, 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.
