From 53f6f30cf097415d6190a4c83fb55bfff2ffc126 Mon Sep 17 00:00:00 2001 From: Benjamin Admin Date: Mon, 4 May 2026 22:09:45 +0200 Subject: [PATCH] feat: DSI document discovery + completeness check in agent scan workflow MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Agent scan now automatically: 1. Discovers all legal documents via consent-tester /dsi-discovery endpoint 2. Classifies each as DSE/AGB/Widerruf/Cookie/Impressum 3. Checks completeness against type-specific checklists: - DSE: 9 Art. 13 DSGVO mandatory fields (controller, DPO, purposes, legal basis, recipients, third-country, retention, rights, complaint) - AGB: §305ff BGB (scope, contract formation, liability, jurisdiction) - Widerruf: §355 BGB (right info, 14-day deadline, form, consequences) 4. Adds findings per document to scan results 5. Shows discovered documents with completeness % in email summary 6. Returns discovered_documents list in API response New files: - dsi_document_checker.py (229 LOC) — checklists + classifier - agent_scan_helpers.py (109 LOC) — extracted summary builder + corrections Refactor: agent_scan_routes.py 537→448 LOC (under 500 budget) Co-Authored-By: Claude Opus 4.6 (1M context) --- .../compliance/api/agent_scan_helpers.py | 109 +++++++++ .../compliance/api/agent_scan_routes.py | 142 +++++------ .../services/dsi_document_checker.py | 229 ++++++++++++++++++ 3 files changed, 402 insertions(+), 78 deletions(-) create mode 100644 backend-compliance/compliance/api/agent_scan_helpers.py create mode 100644 backend-compliance/compliance/services/dsi_document_checker.py diff --git a/backend-compliance/compliance/api/agent_scan_helpers.py b/backend-compliance/compliance/api/agent_scan_helpers.py new file mode 100644 index 0000000..5adcb43 --- /dev/null +++ b/backend-compliance/compliance/api/agent_scan_helpers.py @@ -0,0 +1,109 @@ +""" +Agent scan helpers — summary builder and correction generator. +Extracted from agent_scan_routes.py to keep route file under 500 LOC. +""" + +import logging +import os +import re + +import httpx + +logger = logging.getLogger(__name__) + + +async def add_corrections(findings: list, dse_text: str) -> None: + """Add correction suggestions for pre-launch mode via LLM.""" + for finding in findings: + if finding.severity in ("HIGH", "MEDIUM") and "MISSING" in finding.code: + service_name = finding.code.replace("DSE-MISSING-", "").replace("_", " ").title() + try: + ollama_url = os.environ.get("OLLAMA_URL", "http://host.docker.internal:11434") + ollama_model = os.environ.get("OLLAMA_MODEL", "qwen3.5:35b-a3b") + async with httpx.AsyncClient(timeout=120.0) as client: + resp = await client.post(f"{ollama_url}/api/generate", json={ + "model": ollama_model, + "prompt": ( + f"Erstelle einen einbaufertigen Textbaustein fuer eine deutsche " + f"Datenschutzerklaerung fuer den Dienst '{service_name}'.
