factorizelisted

Scan the codebase to detect duplicated code, repeated patterns, and factorization opportunities. Unlike `/simplify` (which refines recently changed code), this command performs a **project-wide** analysis. **Modes:** - `/factorize` — full scan, all source files - `/factorize src/services` — scoped to a specific directory - `/factorize --dry-run` — report only, no code changes - `/factorize --scope small` — override auto-detected project size ## Step 1 — Context 1. Read `CLAUDE.md` to understand: - Stack (language, framework, conventions) - Project structure (where source lives, what's generated/vendored) - Naming conventions and existing abstractions 2. Detect project size: - Count source files (exclude tests, config, generated, vendor, node_modules) - **Small** (< 30 files): 1 analysis agent - **Medium** (30-100 files): 2 agents (split by directory) - **Large** (> 100 files): 3 agents (split by layer/concern) 3. Present the plan: ``` FACTORIZE — [project name] Stack: [detected] Scope: [full / directory] Size: [X source files] → [small/medium/large] Agents: [1-3] Mode: [analysis + refactor / dry-run (report only)] Proceed? [Y/n] ``` ## Step 2 — Detection phase Launch agents in parallel (subagent_type: `feature-dev:code-explorer`). Each agent receives its assigned files and this mission: ``` You are analyzing [project name] ([stack]) for factorization opportunities. Your assigned files: [list]. Scan for these patterns:
