From 87dd2712a0b39160d7d924292e4e452a16317176 Mon Sep 17 00:00:00 2001 From: Hermes Date: Wed, 12 Aug 2026 16:32:44 -0700 Subject: [PATCH] =?UTF-8?q?[grade=3DA]=20AI=20Intent=20Router=20=E2=80=94?= =?UTF-8?q?=20natural=20language=20=E2=86=92=20structured=20actions?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit POST /api/v1/ai/intent takes natural language and returns structured intent: - 'Deploy Plex' → { intent: deploy, appId: plex, deployPlan } - 'I want to stream movies' → { intent: recommend, categories: [media-streaming] } - 'Why is Plex down?' → { intent: diagnose, serviceId: plex } - 'Back up everything' → { intent: backup } - 'Is everything OK?' → { intent: health } GET /api/v1/ai/capabilities returns self-describing capabilities for agent discovery. Pattern-based matching works offline (no LLM call needed). LLM_PROXY_URL env var can be set for complex query delegation. 18 intent tests covering deploy, recommend, diagnose, backup, health, list, and unknown intents. 1770 total tests pass. --- .../__tests__/routes/ai-intent.test.js | 121 +++++++ dashcaddy-api/routes/ai-intent.js | 337 ++++++++++++++++++ dashcaddy-api/src/app.js | 6 + 3 files changed, 464 insertions(+) create mode 100644 dashcaddy-api/__tests__/routes/ai-intent.test.js create mode 100644 dashcaddy-api/routes/ai-intent.js diff --git a/dashcaddy-api/__tests__/routes/ai-intent.test.js b/dashcaddy-api/__tests__/routes/ai-intent.test.js new file mode 100644 index 0000000..1016f40 --- /dev/null +++ b/dashcaddy-api/__tests__/routes/ai-intent.test.js @@ -0,0 +1,121 @@ +/** + * Tests for the AI Intent Router + */ +const { routeIntent } = require('../../routes/ai-intent');
