Refactor API calls to use csrfFetch for enhanced security across multiple views, including loop-monitor, mcp-manager, memory, prompt-history, rules-manager, session-detail, and skills-manager. Additionally, add Phase 1 and Phase 2 documentation for session initialization and orchestration loop in the ccw-loop-b skill.

+# Worker: DEBUG
+
+Problem diagnosis worker. Hypothesis-driven debugging with evidence tracking.
+
+## Purpose
+
+- Locate error source and understand failure mechanism
+- Generate testable hypotheses ranked by likelihood
+- Collect evidence and evaluate against criteria
+- Document root cause and fix recommendations
+
+## Preconditions
+
+- Issue exists (test failure, bug report, blocked task)
+- `state.status === 'running'`
+
+## Mode Detection
+
+```javascript
+const debugPath = `${progressDir}/debug.md`
+const debugExists = fs.existsSync(debugPath)
+
+const debugMode = debugExists ? 'continue' : 'explore'
+```
+
+## Execution
+
+### Mode: Explore (First Debug)
+
+#### Step E1: Understand Problem
+
+```javascript
+// From test failures, blocked tasks, or user description
+const bugDescription = state.skill_state.findings?.[0]
+  || state.description
+```
+
+#### Step E2: Search Codebase
+
+```javascript
+const searchResults = mcp__ace_tool__search_context({
+  project_root_path: '.',
+  query: `code related to: ${bugDescription}`
+})
+```
+
+#### Step E3: Generate Hypotheses
+
+```javascript
+const hypotheses = [
+  {
+    id: 'H1',
+    description: 'Most likely cause',
+    testable_condition: 'What to check',
+    confidence: 'high | medium | low',
+    evidence: [],
+    mechanism: 'Detailed explanation of how this causes the bug'
+  },
+  // H2, H3...
+]
+```
+
+#### Step E4: Create Understanding Document
+
+```javascript
+Write(`${progressDir}/debug.md`, `# Debug Understanding
+
+**Loop ID**: ${loopId}
+**Bug**: ${bugDescription}
+**Started**: ${getUtc8ISOString()}
+
+---
+
+## Hypotheses
+
+${hypotheses.map(h => `
+### ${h.id}: ${h.description}
+- Confidence: ${h.confidence}
+- Testable: ${h.testable_condition}
+- Mechanism: ${h.mechanism}
+`).join('\n')}
+
+## Evidence
+
+[To be collected]
+
+## Root Cause
+
+[Pending investigation]
+`)
+```
+
+### Mode: Continue (Previous Debug Exists)
+
+#### Step C1: Review Previous Findings
+
+```javascript
+const previousDebug = Read(`${progressDir}/debug.md`)
+// Continue investigation based on previous findings
+```
+
+#### Step C2: Apply Fix and Verify
+
+```javascript
+// If root cause identified, apply fix
+// Record fix in progress document
+```
+
+## Output Format
+
+```
+WORKER_RESULT:
+- action: debug
+- status: success
+- summary: Root cause: {description}
+- files_changed: []
+- next_suggestion: develop
+- loop_back_to: develop
+
+DETAILED_OUTPUT:
+ROOT_CAUSE_ANALYSIS:
+  hypothesis: "H1: {description}"
+  confidence: high
+  evidence: [...]
+  mechanism: "Detailed explanation"
+
+FIX_RECOMMENDATIONS:
+  1. {specific fix action}
+  2. {verification step}
+```
+
+## Clarification Mode
+
+If insufficient information:
+
+```
+CLARIFICATION_NEEDED:
+Q1: Can you reproduce the issue? | Options: [Yes, No, Sometimes] | Recommended: [Yes]
+Q2: When did this start? | Options: [Recent change, Always, Unknown] | Recommended: [Recent change]
+```
+
+## Error Handling
+
+| Error | Recovery |
+|-------|----------|
+| Insufficient info | Output CLARIFICATION_NEEDED |
+| All hypotheses rejected | Generate new hypotheses |
+| >5 iterations | Suggest escalation |
