Add CoSec authentication to a Fetcher client with `@ahoo-wang/fetcher-cosec`: `CoSecConfigurer`, JWT `TokenStorage`, token refresh and 401 retry, 403 handling, device/space IDs, `{tenantId}`/`{ownerId}` attribution and cross-tab sign-in state. Use for login tokens, bearer headers, refresh loops, sign-out on refresh failure or auth redirects. For generic interceptors use fetcher-integration; for React `SecurityProvider`/`RouteGuard`, fetcher-react-hooks.
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-cosec-auth ## Decisions - **`CoSecConfigurer` first**: `new CoSecConfigurer(config).applyTo(fetcher)` registers every interceptor in the right order; register the interceptors by hand only to customize one of them. - **No `tokenRefresher`, no auth**: the Authorization request/response interceptors are registered only when `config.tokenRefresher` is set. Without it only the `CoSec-*` headers and resource attribution apply — no Bearer token is sent even if one is stored. - **Trust only your origins**: by default every request, including an absolute URL on another origin (a pagination link, a download URL), receives the access token and the `CoSec-*` headers with the device ID. Pass `isTrusted: sameOriginTrust` to keep them to the `baseURL` origin and the page origin, or your own `RequestTrust`; relative URLs are always trusted, and an untrusted request is neither authorized nor refreshed. …

How to install
mdr add ahoo-wang/skills/fetcher-cosec-auth@sha256:f307df29d0ead650The 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.
