Plan-B / Option-B migration moved every shell URL/analytics key off the
build-time NEXT_PUBLIC_* env channel and onto runtime config served via
__SHOWCASE_CONFIG__ + getRuntimeConfig(). To prevent a silent regression
where a future change reintroduces a direct process.env.NEXT_PUBLIC_*
read in shell code (which would re-freeze the value at build time and
break no-rebuild env switching), add a focused lint rule.
The rule (copilotkit/no-public-env-shell-read) is implemented as a
custom oxlint JS plugin rule in the existing copilotkit plugin and
enabled under shell-scoped overrides in .oxlintrc.json:
- Errors on process.env.NEXT_PUBLIC_<URL/ANALYTICS> reads in:
showcase/shell-dashboard/src/**, showcase/shell-docs/src/**,
showcase/shell/src/**, showcase/shell-dojo/src/**
- Banned keys: POCKETBASE_URL, SHELL_URL, BASE_URL, OPS_BASE_URL,
INTELLIGENCE_SIGNUP_URL, POSTHOG_KEY, POSTHOG_HOST, SCARF_PIXEL_ID,
GOOGLE_ANALYTICS_TRACKING_ID, REB2B_KEY, REO_KEY
- Intentionally allowed (NOT banned): NEXT_PUBLIC_COMMIT_SHA and
NEXT_PUBLIC_BRANCH (build-stamped artifact identifiers per B10/B11)
and NEXT_PUBLIC_LOCAL_BACKENDS (computed from shared/local-ports.json
at build, local-dev only).
- Excluded files (rule disabled via a follow-up override): MDX content
under shell-docs/src/content/**, runtime-config implementation files,
and *.test.{ts,tsx} / *.spec.{ts,tsx}. oxlint does not support
excludedFiles inside an override block, so the exclusion is expressed
as a later override that sets the rule to off.
Plan-B originally targeted oxlint's eslint/no-restricted-syntax with an
AST-selector regex. oxlint 1.x does not implement that rule (only
no-restricted-globals / no-restricted-imports), so the equivalent guard
is realized as a small custom rule in the existing copilotkit JS plugin
(meta.name=copilotkit), reusing the same plugin loader the repo already
has for require-cpk-prefix and no-single-arg-zod-record.
Verification (red-green): the rule fires on a fixture containing
process.env.NEXT_PUBLIC_POCKETBASE_URL and does NOT fire on a fixture
containing process.env.NEXT_PUBLIC_COMMIT_SHA. Test pins the config via
-c so it works inside git worktrees nested under .claude/worktrees/
where oxlint's automatic upward config search can miss the worktree's
own .oxlintrc.json.
All four shells lint clean: 0 errors of the new rule across
shell-dashboard (114 files), shell-docs (137), shell (29), shell-dojo (6).
Zod 4 made the key schema mandatory for z.record, so the single-argument
z.record(valueType) form is a compile-time error (TS2554) when built against
Zod 4. @copilotkit/react-core declares zod ">=3.0.0", so downstream apps on
Zod 4 are affected; runtime parsing is unaffected under both majors.
- react-core + vue MCPAppsActivityContentSchema: toolInput now uses the
two-argument z.record(z.string(), z.unknown()) form
- react-core defineToolCallRenderer test: same fix for a metadata schema
- add a toolInput field-contract test (round-trips mixed value types)
- add copilotkit/no-single-arg-zod-record oxlint rule (autofix), enabled as
error for packages/**; the incompatibility is type-level, so no runtime
test can guard it while the workspace lockfile pins Zod 3

Replace eslint and prettier with oxlint and oxfmt for faster linting
and formatting across the monorepo. Remove all eslint and prettier
configs, dependencies, and related packages. Add .oxlintrc.json and
.oxfmtrc.json for the new tooling. Update CI workflows and lefthook
hooks accordingly. Reformat codebase with oxfmt.
