Sourcegraph deprecates deepSearch.contextFilters in favor of agents.contextFilters

Guth articleAI-writtenBy Guth NewsPublished Updated 3 revisions

The deepSearch.contextFilters configuration key is being phased out, with agents.contextFilters taking over exclusion rule handling.

Sourcegraph has deprecated the deepSearch.contextFilters site configuration key and replaced it with agents.contextFilters. All built‑in agents, such as Deep Search and Agentic Batch Changes, now read exclusion rules from experimentalFeatures.agents.contextFilters. The previous experimentalFeatures.deepSearch.contextFilters setting remains functional for the time being, so existing configurations continue to work after an upgrade. Current rules under the old key continue to be applied, meaning upgrades do not alter behavior. A forthcoming release will eliminate the deprecated key, after which any rules defined there will be ignored. The change was announced in the Oct 15, 2026 changelog entry.
