From 6e44b63db70eb51230dd8f17eb00690e41262ccd Mon Sep 17 00:00:00 2001 From: Rhys Sullivan <39114868+RhysSullivan@users.noreply.github.com> Date: Sun, 3 May 2026 20:10:14 -0700 Subject: [PATCH] Enforce WorkOS Vault style rules with oxlint Add seven repo-local oxlint rules scoped to packages/plugins/workos-vault/src to keep the provider's Effect-only surface, tagged-error discipline, and typed boundary patterns in place. Rules added: - no-inline-object-type-assertion - no-instanceof-tagged-error - no-manual-tag-check - no-promise-client-surface - no-raw-error-throw - no-redundant-error-factory - no-unknown-shape-probing Adapted to the existing flat scripts/oxlint-plugin-executor/utils.js layout on main; no rules already on main were duplicated. Cleanup in workos-vault to satisfy the new rules: - WorkOSVaultClientError now captures status + message at construction so callers consume typed fields instead of probing unknown causes. - Renamed exported WorkOSVaultSdk to module-private WorkOSVaultPromiseApi and removed it from the public package surface. - Replaced unwrapVaultError + inline shape probes in secret-store with direct typed access on WorkOSVaultClientError. - Introduced a named row type in secret-store.test.ts instead of an inline object type assertion. --- .oxlintrc.jsonc | 14 ++++ .../plugins/workos-vault/src/sdk/client.ts | 73 ++++++++++++++----- .../plugins/workos-vault/src/sdk/index.ts | 1 - .../workos-vault/src/sdk/secret-store.test.ts | 16 ++-- .../workos-vault/src/sdk/secret-store.ts | 42 ++--------- scripts/oxlint-plugin-executor.js | 14 ++++ .../rules/no-inline-object-type-assertion.js | 40 ++++++++++ .../rules/no-instanceof-tagged-error.js | 27 +++++++ .../rules/no-manual-tag-check.js | 25 +++++++ .../rules/no-promise-client-surface.js | 42 +++++++++++ .../rules/no-raw-error-throw.js | 24 ++++++ .../rules/no-redundant-error-factory.js | 52 +++++++++++++ .../rules/no-unknown-shape-probing.js | 32 ++++++++ scripts/oxlint-plugin-executor/utils.js | 57 +++++++++++++++ 14 files changed, 399 insertions(+), 60 deletions(-) create mode 100644 scripts/oxlint-plugin-executor/rules/no-inline-object-type-assertion.js create mode 100644 scripts/oxlint-plugin-executor/rules/no-instanceof-tagged-error.js create mode 100644 scripts/oxlint-plugin-executor/rules/no-manual-tag-check.js create mode 100644 scripts/oxlint-plugin-executor/rules/no-promise-client-surface.js create mode 100644 scripts/oxlint-plugin-executor/rules/no-raw-error-throw.js create mode 100644 scripts/oxlint-plugin-executor/rules/no-redundant-error-factory.js create mode 100644 scripts/oxlint-plugin-executor/rules/no-unknown-shape-probing.js diff --git a/.oxlintrc.jsonc b/.oxlintrc.jsonc index 5a044da96..b6a2517f4 100644 --- a/.oxlintrc.jsonc +++ b/.oxlintrc.jsonc @@ -24,5 +24,19 @@ }, ], }, + "overrides": [ + { + "files": ["packages/plugins/workos-vault/src/**/*.{ts,tsx}"], + "rules": { + "executor/no-inline-object-type-assertion": "error", + "executor/no-instanceof-tagged-error": "error", + "executor/no-manual-tag-check": "error", + "executor/no-promise-client-surface": "error", + "executor/no-raw-error-throw": "error", + "executor/no-redundant-error-factory": "error", + "executor/no-unknown-shape-probing": "error", + }, + }, + ], "ignorePatterns": [".astro/", "**/routeTree.gen.ts", ".references/"], } diff --git a/packages/plugins/workos-vault/src/sdk/client.ts b/packages/plugins/workos-vault/src/sdk/client.ts index 6122921c4..7b2fe37ed 100644 --- a/packages/plugins/workos-vault/src/sdk/client.ts +++ b/packages/plugins/workos-vault/src/sdk/client.ts @@ -1,5 +1,9 @@ import type { WorkOS } from "@workos-inc/node/worker"; -import { WorkOS as WorkOSClient } from "@workos-inc/node/worker"; +import { + GenericServerException, + NotFoundException, + WorkOS as WorkOSClient, +} from "@workos-inc/node/worker"; import { Data, Effect, Result } from "effect"; export interface WorkOSVaultObjectMetadata { @@ -16,10 +20,48 @@ export interface WorkOSVaultObject { readonly value?: string; } +// Minimal shape carrying an HTTP-style status code.
