Raintree blog posts on systems work: what shipped, what changed, what we measured, and what evidence supported the decision.
Current posts across systems problems: packaging crawled knowledge for agents, enforcing local-first web evidence, reducing SQL generation failures, and routing retrieval across crawl/search providers.
DocPull 5.0 ships a local-first evidence workflow for agents: zero-dollar budget enforcement, open discovery, local rendering, provider escalation, and accounting artifacts.
Why DocPull supports OKF export: portable source bundles let agents reuse scraped knowledge without turning every crawl into another custom format.
What grammar constraints buy in practice: fewer SQL failure modes on adversarial schema-drift prompts over live data, not a blanket quality boost.
A practical routing policy for web retrieval: crawl directly when the URL is known, then escalate to providers for discovery, freshness, or archived surfaces.
