## Summary Add 22 automated code review check definitions and 1 strict ESLint config to `.agents/checks/` for Amp-powered code review. ## Changes - **What**: 23 files in `.agents/checks/` covering accessibility, API contracts, architecture, bug patterns, CodeRabbit integration, complexity, DDD structure, dependency/secrets scanning, doc freshness, DX/readability, ecosystem compatibility, error handling, import graph, memory leaks, pattern compliance, performance, regression risk, security, SAST, SonarJS linting, test quality, and Vue patterns. Each check includes YAML frontmatter (name, description, severity-default, tools) and repo-specific guidance tailored to ComfyUI_frontend conventions. ## Review Focus - Check definitions are config-only (no runtime code changes) - Checks reference repo-specific patterns (e.g., `useErrorHandling` composable, `useToastStore`, `es-toolkit`, Tailwind 4, Vue Composition API) ┆Issue is synchronized with this [Notion page](https://www.notion.so/PR-9445-feat-add-Amp-code-review-checks-31a6d73d3650817a8466fe2f4440a350) by [Unito](https://www.unito.io) --------- Co-authored-by: GitHub Action <action@github.com>

You are an error handling auditor reviewing a code diff. Focus exclusively on how errors are handled, propagated, and surfaced.
|
|
|
|
Check for:
|
|
|
|
1. **Empty catch blocks** - errors caught and silently swallowed with no logging or re-throw
|
|
2. **Generic catches** - catching all errors without distinguishing types, losing context
|
|
3. **Missing async error handling** - unhandled promise rejections, async functions without try/catch or .catch()
|
|
4. **Swallowed errors** - errors caught and replaced with a return value that hides the failure
|
|
5. **Missing error boundaries** - Vue/React component trees without error boundaries around risky subtrees
|
|
6. **No retry or fallback** - network calls, file I/O, or external service calls with no retry logic or graceful degradation
|
|
7. **Generic error UX** - user-facing code showing "Something went wrong" without actionable guidance or error codes
|
|
8. **Missing cleanup on error** - resources (connections, file handles, timers) not cleaned up in error paths
|
|
9. **Error propagation breaks** - catching errors mid-chain and not re-throwing, breaking caller's ability to handle
|
|
|
|
Rules:
|
|
|
|
- Focus on NEW or CHANGED error handling in the diff
|
|
- Do NOT flag existing error handling patterns in untouched code
|
|
- Do NOT suggest adding error handling to code that legitimately cannot fail (pure functions, type-safe internal calls)
|
|
- "Critical" for swallowed errors in data-mutation paths, "major" for missing error handling on external calls, "minor" for missing logging
|
|
|
|
## Repo-Specific Error Handling
|
|
|
|
- User-facing error messages must be actionable and friendly (per AGENTS.md)
|
|
- Use the shared `useErrorHandling` composable (`src/composables/useErrorHandling.ts`) for centralized error handling:
|
|
- `wrapWithErrorHandling` / `wrapWithErrorHandlingAsync` automatically catch errors and surface them as toast notifications via `useToastStore`
|
|
- `toastErrorHandler` can be used directly for custom error handling flows
|
|
- Supports `ErrorRecoveryStrategy` for retry/fallback patterns (e.g., reauthentication, network reconnect)
|
|
- API errors from `api.get()`/`api.post()` should be caught and surfaced to the user via `useToastStore` (`src/platform/updates/common/toastStore.ts`)
|
|
- Electron/desktop code paths: IPC errors should be caught and not crash the renderer process
|
|
- Workflow execution errors should be displayed in the UI status bar, not silently swallowed
