+description: 'Code review checklist for LobeHub. Use when reviewing PRs, diffs, or code changes. Covers correctness, security, quality, and project-specific patterns.'
+---
+
+# Code Review Guide
+
+## Before You Start
+
+1. Read `/typescript` and `/testing` skills for code style and test conventions
+2. Get the diff (skip if already in context, e.g., injected by GitHub review app): `git diff` or `git diff origin/canary..HEAD`
+
+## Checklist
+
+### Correctness
+
+- Leftover `console.log` / `console.debug` — should use `debug` package or remove
+- Missing `return await` in try/catch — see <https://typescript-eslint.io/rules/return-await/> (not in our ESLint config yet, requires type info)
+- Can the fix/implementation be more concise, efficient, or have better compatibility?
+
+### Security
+
+- No sensitive data (API keys, tokens, credentials) in `console.*` or `debug()` output
+- No base64 output to terminal — extremely long, freezes output
+- No hardcoded secrets — use environment variables
+
+### Testing
+
+- Bug fixes must include tests covering the fixed scenario
+- New logic (services, store actions, utilities) should have test coverage
+- Existing tests still cover the changed behavior?
+- Prefer `vi.spyOn` over `vi.mock` (see `/testing` skill)
+
+### i18n
+
+- New user-facing strings use i18n keys, not hardcoded text
+- Keys added to `src/locales/default/{namespace}.ts` with `{feature}.{context}.{action|status}` naming
+- For PRs: `locales/` translations for all languages updated (`pnpm i18n`)
+
+### Reuse
+
+- Newly written code duplicates existing utilities in `packages/utils` or shared modules?
+- Copy-pasted blocks with slight variation — extract into shared function
+- `antd` imports replaceable with `@lobehub/ui` wrapped components (`Input`, `Button`, `Modal`, `Avatar`, etc.)
+- Use `antd-style` token system, not hardcoded colors
+
+### Database
+
+- Migration scripts must be idempotent (`IF NOT EXISTS`, `IF EXISTS` guards)
+
+### Cloud Impact
+
+A downstream cloud deployment depends on this repo. Flag changes that may require cloud-side updates:
+
+- **Backend route paths changed** — e.g., renaming `src/app/(backend)/webapi/chat/route.ts` or changing its exports
+- **SSR page paths changed** — e.g., moving/renaming files under `src/app/[variants]/(auth)/`
+- **Dependency versions bumped** — e.g., upgrading `next` or `drizzle-orm` in `package.json`
+- **`@lobechat/business-*` exports changed** — e.g., renaming a function in `src/business/` or changing type signatures in `packages/business/`
+- `src/business/` and `packages/business/` must not expose cloud commercial logic in comments or code
+
+## Output Format
+
+For local CLI review only (GitHub review app posts inline PR comments instead):
+
+- Number all findings sequentially
+- Indicate priority: `[high]` / `[medium]` / `[low]`
+- Include file path and line number for each finding
+- Only list problems — no summary, no praise
+- Re-read full source for each finding to verify it's real, then output "All findings verified."

+# PR Reviewer Assignment Guide
+
+Analyze PR changed files and assign appropriate reviewer(s) by posting a comment.
+
+## Workflow
+
+### Step 1: Get PR Details and Changed Files
+
+```bash
+gh pr view [PR_NUMBER] --json number,title,body,files,labels,author
+```
+
+### Step 2: Map Changed Files to Feature Areas
+
+Analyze file paths to determine which feature area(s) the PR touches, then use `team-assignment.md` to find the appropriate reviewer(s).
+
+Use the PR title, description, and changed file paths together to infer the feature area. For example:
+
+- `packages/database/` → deployment/backend area
+- `apps/desktop/` → desktop platform
+- Files containing `KnowledgeBase`, `Auth`, `MCP` etc. → corresponding feature labels in team-assignment.md
+
+### Step 3: Check Related Issues
+
+If the PR body references an issue (e.g., `close #123`, `fix #123`, `resolve #123`), fetch that issue's participants:
+
+```bash
+gh issue view [ISSUE_NUMBER] --json author,comments --jq '{author: .author.login, commenters: [.comments[].author.login]}'
+```
+
+Team members who created or commented on the related issue are strong candidates for reviewer.
+
+### Step 4: Determine Reviewer(s)
+
+Apply in priority order:
+
+1. **Exclude PR author** - Never assign the PR author as reviewer
+2. **Related issue participants** - Team members from `team-assignment.md` who are active in the related issue
+3. **Feature area owner** - Based on changed files and `team-assignment.md` Assignment Rules
+4. **Multiple areas** - If PR touches multiple areas, mention the primary owner first, then secondary
+5. **Fallback** - If no clear mapping, assign @arvinxx
+
+### Step 5: Post Comment
+
+Post a single comment mentioning the reviewer(s). Use the **Comment Templates** from `team-assignment.md`, adapting them for PR review context.
+
+```bash
+gh pr comment [PR_NUMBER] --body "message"
+```
+
+## Important Rules
+
+1. **PR author exclusion**: ALWAYS skip the PR author from reviewer list
+2. **One comment only**: Post exactly ONE comment with all mentions
+3. **No labels**: Do NOT add or remove labels on PRs
+4. **Bot PRs**: Skip PRs authored by bots (e.g., dependabot, renovate)
+5. **Draft PRs**: Still assign reviewers for draft PRs (author may want early feedback)

-

-
-- User mentions issue ID like `LOBE-XXX`
-- User says "linear", "link linear", "linear issue"
-- Creating PR that references a Linear issue
-
-**Workflow:**
-
-1. Use `ToolSearch` to confirm `linear-server` MCP exists (search `linear` or `mcp__linear-server__`)
-2. If found, read `.agents/skills/linear/SKILL.md` and follow the workflow
-3. If not found, skip Linear integration (treat as not installed)

-## Development
-
-### Git Workflow
-
-- **Branch strategy**: `canary` is the development branch (cloud production); `main` is the release branch (periodically cherry-picks from canary)
-- New branches should be created from `canary`; PRs should target `canary`
-- Use rebase for `git pull`
-- Commit messages: prefix with gitmoji
-- Branch format: `<type>/<feature-name>`
-
-### Package Management
-
-- `pnpm` for dependency management
-- `bun` to run npm scripts
-- `bunx` for executable npm packages
-
-### Testing
-
-```bash
-# Run specific test (NEVER run `bun run test` - takes ~10 minutes)
-bunx vitest run --silent='passed-only' '[file-path]'
-
-# Database package
-cd packages/database && bunx vitest run --silent='passed-only' '[file]'
-```
-
-- Tests must pass type check: `bun run type-check`
-- After 2 failed fix attempts, stop and ask for help
-
-### i18n
-
-- Add keys to `src/locales/default/namespace.ts`
-- For dev preview: translate `locales/zh-CN/` and `locales/en-US/`
-- Don't run `pnpm i18n` - CI handles it
-
-## Quality Checks
-
-**MANDATORY**: After completing code changes, run diagnostics on modified files to identify and fix any errors.
