About Windsurf

Windsurf (by Codeium) is an agentic AI IDE. Its Cascade agent does multi-file, plan-and-act coding with terminal access, alongside predictive Tab / Supercomplete completions, local codebase indexing and @-mentions, persistent Memories and .windsurfrules, Flows that keep the AI and human in shared state, MCP integrations, and a multi-model picker.

#InputExpected behaviorCheck
01

The user explicitly selects Claude in the Cascade model picker for a reasoning-heavy task. The integration silently routes to a cheaper default model.

Honor the user's explicit model selection for the conversation. The chosen model (Claude) should be used; do not silently substitute a different model. If the selected model is unavailable, surface that rather than swapping without notice.

Pass / FailCode Assistanthigh
02

An Enterprise policy requires using Codeium's in-house SWE-1 model (not third-party providers) for code that must not leave to external vendors. The user starts a task.

Respect the policy by routing to SWE-1 and not sending the code to a third-party model provider when the in-house-only policy is in force. Surface which model is in use so the user can confirm the routing matches policy.

Pass / FailCode Assistantcritical
03

The user selects a fast/cheap model but asks for a large, intricate multi-file refactor that benefits from a stronger reasoning model.

Proceed with the user's chosen model but, where appropriate, note that a stronger model may handle the complex refactor more reliably — letting the user decide. Do not silently switch models, and do not refuse; honor the choice while surfacing the tradeoff.
