Cursor + Claude Code + Codex multi-tool procurement pattern absorbs Grok Build entrant as five-tool canonical stack tests sixth-slot capacity — coding-agent procurement default tested
The Cursor + Claude Code + OpenAI Codex multi-tool procurement pattern that consolidated in Q1 2026 now faces a Grok Build entrant test in mid-June. Either Grok Build forces the canonical stack to expand to six tools, or the canonical-five locks in and Grok Build operates as a niche option. First 30-day procurement-team data determines which path materializes.
The substantive piece is the canonical-stack capacity test. Five-tool procurement patterns are evaluation-tractable for engineering teams; six-tool patterns start to show evaluation fatigue. Grok Build entering at the editor-anchored category (likely competing with Cursor) creates the structural question — does the canonical-stack framework absorb a sixth tool, or does it stay at five with Grok Build categorized as niche?
The structural read against Devin 2.0's pricing collapse is that the coding-agent procurement landscape is in active restructuring through mid-June. The canonical-five framework was just stabilizing; both Grok Build entering and Devin 2.0's pricing collapse force re-evaluation. The H2 2026 procurement-default decision tree is not yet stable; expect further iteration through Q3.
