+
+### eslint-plugin-jsdoc
+
+| Rule                  | Status  | Notes                         |

+| `no-restricted-globals` | **Gap** | Restrict window/document/location/navigator |
+
+## Custom Sentry Plugin Rules
+
+The `@sentry-internal/eslint-plugin-sdk` contains 6 custom rules. These can be loaded via Oxlint's JS plugins feature.
+
+| Rule                          | Status      | Notes                                           |
+| ----------------------------- | ----------- | ----------------------------------------------- |
+| `no-eq-empty`                 | **Gap**     | Disallow `=== []` or `=== {}`                   |
+| `no-class-field-initializers` | **Gap**     | Disallow class field initializers (bundle size) |
+| `no-regexp-constructor`       | **Gap**     | Warn about `new RegExp()` usage                 |
+| `no-unsafe-random-apis`       | **Gap**     | Disallow `Math.random()` etc                    |
+| `no-focused-tests`            | **Covered** | Use `jest/no-focused-tests`                     |
+| `no-skipped-tests`            | **Covered** | Use `jest/no-disabled-tests`                    |
+
+## Type-Aware Linting
+
+Type-aware rules require the `--type-aware` flag and `oxlint-tsgolint` package:
+
+```bash
+# Install type-aware package
+yarn add -D oxlint-tsgolint
+
+# Run with type-aware rules
+yarn lint:oxlint:type-aware
+```
+
+Type-aware mode enables additional checks like:
+
+- `typescript/no-floating-promises` (enhanced)
+- `typescript/no-unsafe-member-access` (enhanced)
+- `typescript/unbound-method` (enhanced)
+- `typescript/no-deprecated`
+- `typescript/no-base-to-string`
+- `typescript/restrict-template-expressions`
+
+**Note**: Type-aware linting requires TypeScript 7+ and may need tsconfig adjustments.
+
+## Current Errors Found by Oxlint
+
+As of migration, Oxlint identifies the following issues that ESLint may not have caught:
+
+### Complexity Issues (21 functions)
+
+Functions exceeding cyclomatic complexity of 20:
+
+- `getNotificationAttributes` (31)
+- `constructor` in replay integration (32)
+- `xhrCallback` (27)
+- `_INTERNAL_captureLog` (28)
+- And others...
+
+### Unused Variables
+
+- Unused catch parameters not prefixed with `_`
+- Unused function declarations
+
+### Code Quality
+
+- Bitwise operations (intentionally used in replay packages)
+- Missing return types on some callback functions
+
+## Recommendations
+
+1. **JS Plugins**: Load the custom Sentry plugin via `jsPlugins` config option
+2. **Prettier Integration**: Use Prettier for import sorting since `simple-import-sort` is not supported
+3. **Type-Aware**: Enable type-aware linting in CI for enhanced TypeScript checks
+4. **Fix Incrementally**: Address the 71+ errors found by Oxlint over time
+
+## Performance Comparison
+
+```
+ESLint (packages/core + packages/browser):
+  Time: ~8 seconds
+
+Oxlint (same files):
+  Time: 24ms
+  Speedup: ~330x
+```

+## Migration Steps Completed
+
+1. Created root `.oxlintrc.json` with base rules from `@sentry-internal/sdk` ESLint config
+2. Created `.oxlintrc.json` in each package that `extends` the root config (mirrors ESLint structure)
+3. Updated all `package.json` lint scripts from `eslint . --format stylish` to `oxlint .`
+4. Updated eslint-disable comments to use Oxlint rule names where needed:
+   - `@sentry-internal/sdk/no-skipped-tests` → `jest/no-disabled-tests`
+   - `@typescript-eslint/prefer-for-of` → `typescript/prefer-for-of`
+5. Fixed actual code issues found:
+   - Redundant `type` modifier in imports
+   - Missing `import type` in `.d.ts` files
+
+## Rules Status After Re-evaluation
+
+### Downgraded to Warning
+
+| Rule             | Status | Errors if enabled | Reason                                   |
+| ---------------- | ------ | ----------------- | ---------------------------------------- |
+| `complexity`     | `warn` | 26 errors         | Many functions exceed limit of 20        |
+| `no-unused-vars` | `off`  | 22 errors         | Catch params like `e`, `err` not ignored |
+
+### Test File Overrides Not Working from Root
+
+The glob patterns in root `.oxlintrc.json` overrides like `**/test/**` don't work when running from root.
+Workaround: Rules for test files need to be disabled globally or in package-specific configs.
+
+## Ignored Files/Directories
+
+These were added to `ignorePatterns` to silence errors in vendored/generated code:
+
+| Package          | Ignored                                       | Reason                    |

+| `replay-worker`  | `examples/worker.js`                          | Vendored/minified code    |
+| `profiling-node` | `scripts/**`                                  | Build scripts             |

 **Note**: Type-aware linting requires TypeScript 7+ and may need tsconfig adjustments.
 
-## Current Errors Found by Oxlint
-
-As of migration, Oxlint identifies the following issues that ESLint may not have caught:
-
-### Complexity Issues (21 functions)
-
-Functions exceeding cyclomatic complexity of 20:
-
-- `getNotificationAttributes` (31)
-- `constructor` in replay integration (32)
-- `xhrCallback` (27)
-- `_INTERNAL_captureLog` (28)
-- And others...
-
-### Unused Variables
-
-- Unused catch parameters not prefixed with `_`
-- Unused function declarations
-
-### Code Quality
-
-- Bitwise operations (intentionally used in replay packages)
-- Missing return types on some callback functions
-
 ## Recommendations
 
-1. **JS Plugins**: Load the custom Sentry plugin via `jsPlugins` config option
+1. **JS Plugins**: Load the custom Sentry plugin via `jsPlugins` config option for missing rules
 2. **Prettier Integration**: Use Prettier for import sorting since `simple-import-sort` is not supported
 3. **Type-Aware**: Enable type-aware linting in CI for enhanced TypeScript checks
-4. **Fix Incrementally**: Address the 71+ errors found by Oxlint over time
+4. **Re-enable Rules**: Periodically review the "Rules Disabled for Re-evaluation" section

 5. Fixed actual code issues found:
    - Redundant `type` modifier in imports
    - Missing `import type` in `.d.ts` files
+6. Removed all `.eslintrc.js` and `.eslintrc.cjs` files from the codebase (61 files total)
+
+## ESLint Cleanup
+
+All ESLint configuration files have been removed from the codebase:
+
+- Removed 50 `.eslintrc.js` files from packages/, dev-packages/, and root
+- Removed 11 `.eslintrc.cjs` files from packages/ and dev-packages/
+
+**Kept**:
+
+- `packages/eslint-config-sdk` - Published ESLint config for SDK users
+- `packages/eslint-plugin-sdk` - Published ESLint plugin for SDK users
+- ESLint in `dev-packages/e2e-tests/test-applications/*` - These are real framework test apps that use ESLint
+
+**Configuration hierarchy now**:
+
+- `.oxlintrc.json` (root) - Base rules
+- `packages/*/.oxlintrc.json` - Extends root, package-specific overrides
+- `dev-packages/*/.oxlintrc.json` - Extends root, dev-package-specific overrides
 
 ## Rules Status After Re-evaluation
 
@@ -184,6 +204,33 @@ Oxlint (full repo with type-aware):
 
 All packages lint in under 100ms with Oxlint.
 
+## Next Steps
+
+### Short Term
+
+1. **Address remaining warnings (45)** - Review the `complexity` warnings and consider refactoring functions that exceed the limit of 20
+2. **Enable type-aware linting in CI** - Add `yarn lint:oxlint:type-aware` to CI for enhanced TypeScript checks (catches more bugs but slower)
+3. **Update pre-commit hooks** - If using husky/lint-staged, update to use `oxlint` instead of `eslint`
+
+### Medium Term
+
+4. **Implement custom Sentry rules via JS plugins** - Port the 4 remaining custom rules from `@sentry-internal/eslint-plugin-sdk`:
+   - `no-eq-empty` - Disallow `=== []` or `=== {}`
+   - `no-class-field-initializers` - Disallow class field initializers (bundle size)
+   - `no-regexp-constructor` - Warn about `new RegExp()` usage
+   - `no-unsafe-random-apis` - Disallow `Math.random()` etc
+5. **Re-evaluate disabled rules** - Periodically check if `no-unused-vars` can be re-enabled with better catch param handling
+6. **Import sorting** - Consider using Prettier or dprint for import sorting since `simple-import-sort` is not supported
+
+### Long Term
+
+7. **Deprecate `eslint-config-sdk` and `eslint-plugin-sdk`** - Once Oxlint adoption is widespread, consider deprecating these packages or providing Oxlint equivalents
+8. **Monitor Oxlint releases** - Track new rule support in Oxlint releases that may fill current gaps:
+   - `@typescript-eslint/member-ordering`
+   - `@typescript-eslint/naming-convention`
+   - `import/no-extraneous-dependencies`
+   - `jsdoc/require-jsdoc`
