Anchor's Action Index lets web agents replay proven workflows as code, cutting per-task cost ~98x
Action Index stores web workflows that already succeeded and replays them as deterministic code, calling the model only on steps where the page changed; in Anchor's Online-Mind2Web test, gpt-5.6-luna with it hit 93.3% at $0.016 per task versus claude-opus-5's 93.0% at $1.57. It's on every Anchor plan including free, via search_action_index/execute_action_index tools on https://api.anchorbrowser.io/v1/mcp or the REST API.
