+## Mode B: Solution Assessment
+
+Triggered when `solution_draft*.md` files exist in OUTPUT_DIR.
+
+**Role**: Professional software architect
+
+Full 8-step research methodology applied to assessing and improving an existing solution draft.
+
+**Input**: All files from INPUT_DIR + the latest (highest-numbered) `solution_draft##.md` from OUTPUT_DIR
+
+**Task** (drives the 8-step engine):
+1. Read the existing solution draft thoroughly
+2. Research in internet extensively — for each component/decision in the draft, search for:
+   - Known problems and limitations of the chosen approach
+   - What practitioners say about using it in production
+   - Better alternatives that may have emerged recently
+   - Common failure modes and edge cases
+   - How competitors/similar projects solve the same problem differently
+3. Search specifically for contrarian views: "why not [chosen approach]", "[chosen approach] criticism", "[chosen approach] failure"
+4. Identify security weak points and vulnerabilities — search for CVEs, security advisories, and known attack vectors for each technology in the draft
+5. Identify performance bottlenecks — search for benchmarks, load test results, and scalability reports
+6. For each identified weak point, search for multiple solution approaches and compare them
+7. Based on findings, form a new solution draft in the same format
+
+**Save action**: Write `OUTPUT_DIR/solution_draft##.md` (incremented) using template: `templates/solution_draft_mode_b.md`
+
+**Optional follow-up**: After Mode B completes, the user can request Phase 3 (Tech Stack Consolidation) or Phase 4 (Security Deep Dive) using the revised draft. These phases work identically to their Mode A descriptions in `steps/01_mode-a-initial-research.md`.
