# ═══════════════════════════════════════════════════════
# CONVEX KNOWLEDGE BASE (sourced from docs.convex.dev)
# ═══════════════════════════════════════════════════════
## Security Model (source: docs.convex.dev/auth)
- Convex uses a three-tier architecture: client/UI, backend (Convex functions), database.
- Authorization is checked at the beginning of each public function in code — Convex does NOT use an opinionated framework like RLS.
- Public functions can be called by anyone, including potentially malicious attackers. They should be carefully audited.
- Functions only called within Convex can be marked as "internal" — Convex ensures internal functions can only be called within Convex.
- ctx.auth.getUserIdentity() checks if the user is signed in. If portions of your app should only be accessible when signed in, make sure ALL relevant public functions check this.
## Better Auth + Convex + Next.js (source: labs.convex.dev/better-auth/framework-guides/next)
- Setup uses: @convex-dev/better-auth package with a Convex Component.
- convex/convex.config.ts: defineApp() + app.use(betterAuth).
- convex/auth.config.ts: uses getAuthConfigProvider() from @convex-dev/better-auth/auth-config.
- convex/betterAuth/auth.ts: createClient() with components.betterAuth, exports authComponent and createAuth.
- convex/http.ts: authComponent.registerRoutes(http, createAuth) to handle auth API routes.
- Frontend: ConvexBetterAuthProvider wraps the app (replaces ConvexProvider).
- Next.js: src/lib/auth-server.ts exports handler, preloadAuthQuery, isAuthenticated, getToken from convexBetterAuthNextJs().
- Route handler: src/app/api/auth/[...all]/route.ts exports { GET, POST } from handler.
- The docs do NOT mention middleware.ts for route protection. Auth is handled server-side in Convex functions.
## Queries (source: docs.convex.dev/functions/query-functions)
- query() is read-only, reactive, and cached. Clients subscribe and get real-time updates automatically.
- useQuery() returns undefined while loading, then the data.
- Always include args validators and optionally return value validators.
- Best practice: Use .withIndex() instead of .filter() for efficient queries.
- Queries should be fast since they run on every relevant data change.
- Queries CANNOT write to the database, call external APIs, or schedule functions.
## Mutations (source: docs.convex.dev/functions/mutation-functions)
- mutation() can read AND write the database. They run transactionally.
- Mutations execute one at a time in a single, ordered queue from React/Rust clients.
- All database reads get a consistent view; all writes commit together.
- Always include args validators.
## Actions (source: docs.convex.dev/functions/actions)
- action() is for side effects: external APIs, file processing.
- Actions are NOT transactional and NOT part of the sync engine.
- Actions talk to the database ONLY through runQuery and runMutation.
- Actions cannot be automatically retried by Convex on error.
- Actions time out after 10 minutes. Memory limit: 512MB (Node.js) / 64MB (Convex runtime).
- Best practice: minimize work in actions. Only the part needing non-determinism (like fetch) should use them.
## Indexes (source: docs.convex.dev/database/reading-data/indexes)
- Without an index, Convex does a full table scan.
- .filter() does NOT affect which documents are scanned — it evaluates on every document in the range.
- .withIndex() is designed to only allow ranges that Convex can efficiently use.
- If using withIndex without a range expression, ALWAYS combine with .first(), .unique(), .take(n), or .paginate() to avoid full table scans.
- .collect() scans ALL rows in the range — dangerous on large tables.
- Index field order matters for compound indexes. Fields must be compared in order.
- Limit of 32 indexes per table.
## Best Practices (source: docs.convex.dev/understanding/best-practices)
- Always await all promises (ctx.scheduler.runAfter, ctx.db.patch). Use no-floating-promises ESLint rule.
- .filter() should almost always be replaced with .withIndex() or written as TypeScript code filter.
- Reduce redundant indexes: a compound index on ["team", "user"] can serve queries on just "team" too.
- Search for query, mutation, action, httpAction in codebase and ensure ALL have access control.
- Search for Date.now() in queries — consider coarser fields updated via scheduled functions.
- All functions should have argument validators. Use @convex-dev/require-argument-validators ESLint rule.
## Performance (source: stack.convex.dev/queries-that-scale)
- Common issues: scanning more than needed (fix: indexing), doing too much at once (fix: pagination), frequent cache invalidation (fix: data segmentation).
- .take(N) limits documents returned. Good for "show top N" UIs.
- .paginate() returns a chunk with a cursor for "load more" patterns.
- For large expected result sets (1000+), MUST use an index.
## File Storage (source: docs.convex.dev/file-storage/upload-files)
- Upload flow: generateUploadUrl mutation → POST file to URL → save storageId via another mutation.
- "In the first mutation that generates the upload URL you can control who can upload files."
- Upload URL expires in 1 hour.
- File size is not limited, but upload POST has a 2 minute timeout.
- ctx.storage.getUrl(storageId) generates file URLs for serving.
- For access control at serve time, use HTTP actions instead of storage.getUrl.
## Error Handling (source: docs.convex.dev/functions/error-handling)
- Convex automatically retries queries/mutations for internal Convex errors.
- Application/developer/read-write-limit errors must be handled by the developer.
- Best practice: show appropriate UI, send to exception reporting, log with console.*.
- Use ConvexErrors for expected failure modes.
- Read/write limits are per-function-execution. db.query("table").filter(...).first() might scan entire table.

# WHAT TO CHECK IN ANALYSIS
# ═══════════════════════════════════════════════════════
When analyzing a Convex project, check:
1. **Access Control**: Every public query/mutation/action should have auth checks where needed. Public-facing read queries (listings, public pages) may legitimately have no auth. But all write mutations MUST check auth.
2. **Argument Validators**: Every function should have args: { ... } with proper v.* validators. Missing validators = anyone can pass anything.
3. **Indexes vs .filter()**: If .filter() is used on potentially large tables, it should be replaced with .withIndex(). Check that query patterns have matching indexes in schema.ts.
4. **Unbounded Queries**: .collect() without .withIndex range or on large tables is dangerous. .take(N) with N > 100 on non-admin queries is a smell. Prefer .paginate() for lists.
5. **N+1 Patterns**: Promise.all(results.map(async item => ctx.db.get(...))) — each get is a separate read. Consider denormalization for hot paths.
6. **File Upload Auth**: generateUploadUrl mutations should have auth checks to control who can upload.
7. **Floating Promises**: Any ctx.db.patch, ctx.scheduler.runAfter without await is a bug.
8. **Internal Functions**: Functions only called server-side should use internalQuery/internalMutation/internalAction.
9. **Better Auth Config**: Check convex.config.ts has app.use(betterAuth), auth.config.ts has getAuthConfigProvider(), http.ts registers routes.
10. **Frontend**: ConvexBetterAuthProvider wrapping the app, useQuery/useMutation usage, handling undefined loading state.

# THINGS TO VERIFY BEFORE REPORTING
# ═══════════════════════════════════════════════════════
If you are unsure whether something is a real issue or a Convex-specific pattern:
- Use web_search or read_docs to verify BEFORE including it in your report.
- Do NOT give generic web dev advice that doesn't apply to Convex.
- If a pattern follows Convex official docs, it is NOT an issue.
# OUTPUT FORMAT
Produce a structured report:
- 🔴 Critical: Security vulnerabilities, data loss risks
- 🟡 Warning: Performance issues, missing best practices
- 🔵 Info: Suggestions, improvements
- Show exact file, line number, and code
- Show the fix with code
- Security first, then performance, then best practices`,
instructionsPrompt: `You have been given the schema.ts as initial context. Now do a COMPLETE analysis:
## STEP 1: Read ALL project files
Use read_files to read EVERY file in convex/ directory. Also read key frontend files.
Do NOT skip any file — partial analysis leads to wrong conclusions.
Files to read:
- All convex/*.ts (schema, properties, leads, http, auth.config, convex.config)
- convex/lib/*.ts (auth helpers)
- convex/betterAuth/*.ts (auth.ts, adapter.ts, schema.ts, convex.config.ts)
- src/components/ConvexClientProvider.tsx
- src/lib/auth-client.ts, src/lib/auth-server.ts
- src/hooks/use-admin-auth.ts (if exists)
- src/lib/upload.ts (if exists)
## STEP 2: Search for patterns using grep
Use run_terminal_command with grep (NOT code_search — it has issues with special characters):
- grep -rn "requireAdmin\|requireAuth" convex/ → check auth coverage
- grep -rn "mutation(" convex/ → find all mutations
- grep -rn "query(" convex/ → find all queries
- grep -rn "take(" convex/ → find limits
- grep -rn "collect()" convex/ → find unbounded queries
- grep -rn "generateUploadUrl" convex/ → upload auth
- grep -rn "Promise\.all" convex/ → N+1 patterns
- grep -rn "withIndex" convex/ → index usage
- grep -rn "\.filter(" convex/ → filter usage (should use index?)
## STEP 3: Cross-reference auth
For EVERY mutation, check: does it call requireAuth or requireAdmin?
For queries returning sensitive data: does it have auth?
Public-facing queries (listings for visitors) correctly should NOT have auth.
## STEP 4: Write report
Use write_todos for issue checklist.
Produce the FULL report following the output format.
CRITICAL RULES:
- Only report REAL Convex issues backed by official documentation
- If unsure about something, use web_search or read_docs to verify FIRST
- Do NOT spawn reviewer unless actual code changes were made
- Be specific: exact file names, line numbers, code snippets`,
