Upgrade a project from Fetcher 5.x to 6.0. Use when asked to upgrade `@ahoo-wang/fetcher*` to 6; when hooks or options (Wow query hooks, data-monitor hooks, `setQuery`, `propagateError`) are missing from `@ahoo-wang/fetcher-react`; when deprecated `fetcher-wow`, `fetcher-generator` or `fetcher-viewer` must go; or when behavior changed after the upgrade. Decides stay-on-5.x versus upgrade, then rewrites usages. Not for new Fetcher code.
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
# fetcher-v6-migration Fetcher **6.0.0 is published** (`latest` on npm). It does two breaking things: (1) the Wow-coupled packages left fetcher — `@ahoo-wang/fetcher-wow`, `@ahoo-wang/fetcher-generator` and `@ahoo-wang/fetcher-viewer` are **deprecated on npm** and replaced by Wow's `@ahoo-wang/wow-*` packages; (2) `@ahoo-wang/fetcher-react` is **redesigned around cancellation** (hooks and options removed, queries controlled, `execute` never rejects). `@ahoo-wang/fetcher`, `-decorator`, `-eventbus`, `-eventstream`, `-openai`, `-openapi`, `-storage` and `-cosec` keep their API but **change behavior** in ways that pass `tsc` (section 4). Source of truth: the fetcher repository's `docs/releases/v6.0.0.md`. ## 1. Check npm — never assume ```sh npm view @ahoo-wang/fetcher dist-tags # latest: 6.x; release-5 only once a 5.x patch ships after 6.0 npm view @ahoo-wang/wow-client version peerDependencies # 9.2.1 or later: fetcher peer ^5.1.5 || ^6.0.0 npm view @ahoo-wang/fetcher-wow deprecated # the deprecation message names the replacement ``` …

How to install
mdr add ahoo-wang/skills/fetcher-v6-migration@sha256:6af03e6a460601f4The line at the top of this page pins the label git:20261004.2702e5d, 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.
