From 390005f3ad8cd35319df19cc525950df8310c698 Mon Sep 17 00:00:00 2001 From: tikidragonslayer Date: Fri, 1 May 2026 23:46:51 -0400 Subject: [PATCH] feat(talentos): real Genkit-powered job-context extraction (kills mock-keyword charging path) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Public claim: "AI Job Context Builder — chat with our agent to extract Job DNA and hidden requirements" — charges 1 OS Credit per call. Stub evidence (pre-fix): src/app/actions/job-context-actions.ts:73-95 returned canned text from `transcript.toLowerCase().includes('remote'|'fast'|'ship'|'mentor')` heuristics behind a 1.5s setTimeout. Same 4-line analysis was returned regardless of transcript content. Charged the credit. Build slice: - New src/ai/flows/extract-job-context.ts — Genkit flow mirroring the existing anonymize-job-description.ts pattern. Structured Zod output schema (cultureAnalysis, hiddenRequirements[2-6], teamDynamic, recommendedKeywords[3-8]). Prompt grounded in transcript with injection-defense framing matching match-candidate-to-job.ts. - Action wired to extractJobContext(). When AI is unavailable (GOOGLE_GENAI_API_KEY missing) the action FAILS CLOSED, refunds the credit, and surfaces the error message — no canned-data fallback. Pattern follows Codex's no-mocks-in-production doctrine (stubbed-feature-build-architecture-for-claude.md §2). Different from existing flows that fall back to deterministic algos: this one had no real algorithm to fall back to, only fake data. Out of scope (separate slices): - src/components/jobs/active-job-context-builder.tsx:55 "Simple mock conversation flow" — chat UI hardcodes 1 follow-up question; needs real conversation generator - src/lib/firebase-admin.ts:34-37 — production fallback to mock-project-id / mock@example.com — should fail closed in prod - Employer "verification coming soon" Verification: - npx tsc --noEmit shows 0 new errors in changed files. 4 pre-existing Stripe API version errors on main (apiVersion '2025-04-30.basil' vs installed types '2025-02-24.acacia') NOT touched per surgical-changes. - npm run build: compile step succeeded in 24.3s; build's final typecheck fails on the same 4 pre-existing Stripe errors. Worth a separate fix.
