From c9e6c5dcc877fbb9169ad031d9d0073da699f5b3 Mon Sep 17 00:00:00 2001 From: ADOrganization <253949741+viperrcrypto@users.noreply.github.com> Date: Wed, 8 Apr 2026 01:31:56 -0400 Subject: [PATCH] feat: add AI category suggestions with security hardening Based on PR #46 by Microck, rebased onto current main with fixes: - Add prompt injection protection: sanitize tweet content in prompts, use XML delimiters, instruct model to ignore embedded instructions - Cap POST at 20 categories per request to prevent abuse - Validate suggestion fields before creating categories - Fix useEffect missing dependencies (fetchSuggestions, suggestions.length) - Truncate/clamp name, description, confidence values - Validate slug format before DB insert - Don't leak internal error messages from SDK failures Co-Authored-By: Microck <45483921+Microck@users.noreply.github.com> Co-Authored-By: Claude Opus 4.6 (1M context) --- app/api/categories/suggest/route.ts | 77 ++++++++ app/categories/page.tsx | 269 ++++++++++++++++++++++++- lib/category-suggester.ts | 291 ++++++++++++++++++++++++++++ 3 files changed, 628 insertions(+), 9 deletions(-) create mode 100644 app/api/categories/suggest/route.ts create mode 100644 lib/category-suggester.ts diff --git a/app/api/categories/suggest/route.ts b/app/api/categories/suggest/route.ts new file mode 100644 index 0000000..ce8f377 --- /dev/null +++ b/app/api/categories/suggest/route.ts @@ -0,0 +1,77 @@ +import { NextRequest, NextResponse } from 'next/server' +import { + generateCategorySuggestions, + createCategoryFromSuggestion, + CategorySuggestion, +} from '@/lib/category-suggester' + +export async function GET(): Promise { + try { + const suggestions = await generateCategorySuggestions() + return NextResponse.json({ suggestions }) + } catch (err) { + console.error('Category suggestion error:', err) + return NextResponse.json( + { error: err instanceof Error ?
