Building web agents: filtering bad URLs to save context tokens
Chris__Codes · reddit · 2026-08-25
While building agentic workflows, the author noticed that agents waste context by scraping full Markdown payloads for URLs that turn out to be login walls, nav pages, or irrelevant.
The author explored a tool that returns page metadata (structure, category, ranked snippets) alongside text, allowing the agent to evaluate utility before processing the full payload.
The post asks the community for strategies: do you implement pre-processing to filter these pages, or do you pass raw markdown directly to the model?
