skills/objectui: the published data-integration guide and its eval teach @objectstack/plugin-msw / MSWPlugin, a package removed in 12.0 whose last release is 11.0.0 #27678
Description
domain:devx#2 · os-justin · session_01QSeKYmTYfaPbLQD4BJfomW
Filing gate ①: a wrong instruction in shipped text, with named locations. It came out of PR #27576 (#25919): dev report 6498180390 out_of_scope_findings, with the carrier set to the seat, and contract review 6502595750. Filed by domain:devx seat 2 (#20163). ⛔ Not a claim. ⛔ Filed without domain:*: skills/** is a governed surface that ships with npx skills add (domain:skills); the console remnants in item 3 are ui/**. Triage sets the lane or splits.
Business reason: a customer agent that loads the objectui skill and asks for frontend-first development is told to import { MSWPlugin } from '@objectstack/plugin-msw'. That package was removed in 12.0 (7087cfe6e3, "remove unused HTTP adapters (keep Hono only) + MSW plugin (12.0)", #2391). Its last npm release is 11.0.0, which is not deprecated on the registry, so the install succeeds and pulls an 11.x plugin into an 18.x stack. The skill's own eval rewards the answer. North Star 优先级 item 4 counts a shipped sentence that says something wrong.
Reader who acts: the lane triage assigns. One os-dev, one PR.
Dedupe: plugin-msw / MSWPlugin grepped over skills/ and ui/ at origin/main, and issues searched for data-integration.md msw → no card. PR #27576 fixed the internal ui/.claude guide only (S1); this card covers the published side.
Measured (origin/main)
skills/objectui/guides/data-integration.md::354–~410, § "MSW mock setup (frontend-first development)":import { MSWPlugin } from '@objectstack/plugin-msw',kernel.use(new MSWPlugin({ enableBrowser: true, baseUrl: '/api/v1', … })), and astartMockServerapp entry;:510, a pitfall bullet about awaitingstartMockServer().
skills/objectui/evals/data-integration.json:25–31: an eval whoseexpected_outputis "MSW browser setup using ObjectKernel + …" and whose assertions include"MSWPlugin".- Console remnants (

⚠️ ui/packages/app-shell/src/observability/committed-telemetry-endpoint.test.ts:118,136namesVITE_USE_MOCK_SERVERin its fixtures. Measure what it pins before removing the env lines.
- Registry:
npm view @objectstack/plugin-mswreports latest11.0.0, not deprecated.
Wanted
- Replace the guide's MSW section with what the platform supports for frontend-first development today, measured from the tree. For example, run the real backend locally with
objectstack devand an in-memory driver, or remove the section if nothing replaces it. - Update or retire the eval to match. Keep the skill's line budget net-negative or neutral.
- Remove the dead console remnants, or record why each stays.
- Whether to deprecate
@objectstack/plugin-mswon npm is a release action, so it goes to the maintainer and is not done by the lane.
Acceptance
git grep -n 'plugin-msw\|MSWPlugin' -- skills→ 0 hits.- The
objectuiskill's evals pass. git grep -n 'VITE_USE_MOCK_SERVER\|vendor-msw' -- ui/apps→ 0 hits, or a stated reason for each survivor.
