Agent-Generated Deterministic Scrapers: Generate, Validate, Re-Verify
zeeg · x · 2026-09-04
Sentry engineer zeeg breaks down his agent-driven scraping loop:
- Agent generates the scraper using a set of selector/typed capabilities describing the target site;
- A validator proves the agent's generation works (inputs match outputs);
- Periodic re-validation occasionally checks the site content hasn't changed and selectors aren't falsely matching.
He admits the last step is the weakest link, but says the core loop was easy and effective to build. Replying to chanian's skepticism that agents add little for reliable static scraping, the point is clear: keep the agent at generation time, keep execution deterministic.
