 # Workflow Init Command (/workflow:init)

+Initializes `.workflow/project.json` with comprehensive project understanding by leveraging **cli-explore-agent** for intelligent analysis and **memory discovery** for SKILL package indexing.
 
 **Key Features**:
 - **Intelligent Project Analysis**: Uses cli-explore-agent's Deep Scan mode
 - **Technology Stack Detection**: Identifies languages, frameworks, build tools
 - **Architecture Overview**: Discovers patterns, layers, key components
+- **Memory Discovery**: Scans and indexes available SKILL packages
+- **Smart Recommendations**: Suggests memory commands based on project state
 - **One-time Initialization**: Skips if project.json exists (unless --regenerate)

+• /workflow:plan "feature description" - Start new workflow

+### Phase 5: Discover Memory Resources
+
+**Goal**: Scan and index available SKILL packages (memory command products) using agent delegation
+
+**Invoke general-purpose agent** to discover and catalog all memory products:
+
+```javascript
+Task(
+  subagent_type="general-purpose",
+  description="Discover memory resources",
+  prompt=`
+Discover and index all memory command products: SKILL packages, documentation, and CLAUDE.md files.
+
+## Discovery Scope
+1. **SKILL Packages** (.claude/skills/) - Generated by /memory:skill-memory, /memory:tech-research, etc.
+2. **Documentation** (.workflow/docs/) - Generated by /memory:docs
+3. **Module Docs** (**/CLAUDE.md) - Generated by /memory:update-full, /memory:update-related
+
+## Discovery Tasks
+
+### 1. Scan SKILL Packages
+- List all directories in .claude/skills/
+- For each: extract name, classify type, record path
+- Types: workflow-progress | codemap-* | style-* | tech_stacks | project_docs
+
+### 2. Scan Documentation
+- List directories in .workflow/docs/
+- For each project: name, path, check README.md, ARCHITECTURE.md existence
+
+### 3. Scan CLAUDE.md Files
+- Find all **/CLAUDE.md (exclude: node_modules, .git, dist, build)
+- Return path list only
+
+### 4. Identify Gaps
+- No project SKILL? → "project_skill"
+- No documentation? → "documentation"
+- Missing tech stack SKILL? → "tech_stack"
+- No workflow-progress? → "workflow_history"
+- <10% modules have CLAUDE.md? → "module_docs_low_coverage"
+
+### 5. Return JSON:
+{
+  "skills": [
+    {"name": "claude_dms3", "type": "project_docs", "path": ".claude/skills/claude_dms3"},
+    {"name": "workflow-progress", "type": "workflow_progress", "path": ".claude/skills/workflow-progress"}
+  ],
+  "documentation": [
+    {
+      "name": "my_project",
+      "path": ".workflow/docs/my_project",
+      "has_readme": true,
+      "has_architecture": true
+    }
+  ],
+  "module_docs": [
+    "src/core/CLAUDE.md",
+    "lib/utils/CLAUDE.md"
+  ],
+  "gaps": ["tech_stack", "module_docs_low_coverage"]
+}
+
+## Context
+- Project tech stack: ${JSON.stringify(analysis.technology_stack)}
+- Check .workflow/.archives for session history
+- If directories missing, return empty state with recommendations
+  `
+)
+```
+
+**Agent Output**: JSON structure with skills, documentation, module_docs, and gaps
+
+**Update project.json**:
+```javascript
+const memoryDiscovery = JSON.parse(agentOutput);
+
+projectMeta.memory_resources = {
+  ...memoryDiscovery,
+  last_scanned: new Date().toISOString()
+};
+
+Write('.workflow/project.json', JSON.stringify(projectMeta, null, 2));
+```
+
+**Output Summary**:
+```
+Memory Resources Indexed:
+- SKILL Packages: ${skills.length}
+- Documentation: ${documentation.length} project(s)
+- Module Docs: ${module_docs.length} file(s)
+- Gaps: ${gaps.join(', ') || 'none'}
+```

+### Memory Discovery Failures
+
+**Missing Directories**:
+```
+If .claude/skills, .workflow/docs, or CLAUDE.md files not found:
+1. Return empty state for that category
+2. Mark in gaps.missing array
+3. Continue initialization
