[ Against the 9 Standards ]

Based on public documentation as of 2026-08-11. ✓ documented · ~ partial · ✗ not offered · ? unknown. Methodology on the about page.

~ Multi-dimensional Context

Reviews the diff plus rule files, surrounding code, and the PR comment thread; no codebase index.

✓ Rule-Centric & Default Quiet

Path-scoped .cursor/BUGBOT.md rules plus org-wide team rules; deliberately quiet, bug-only scope.

✗ Dual-Workflow: Local vs. PR

PR-only reviewer; 'Fix in Cursor' hands findings to the editor, but there is no local review mode.

✗ Business Logic Validation

No ticket or process integrations - deliberately out of scope.

~ Continuous Learning

Generates learned repo rules from team activity; reads existing PR comments to avoid duplication.

✗ Sandbox Validation

No documented sandbox execution or test generation; static diff analysis with effort levels.

✗ Economic Transparency

No BYOK or model pinning; per-run cost (~$1.00-1.50) is visible but models are Cursor-selected.

~ Actionability

'Fix in Cursor' opens findings in the editor with context; no one-click commit from the PR itself.

? Measurable ROI

Cursor reports ~80% resolution rates for itself; customer-facing ROI dashboards not documented.
