Phase 5: Multi Session Integration (Anthropic Pattern)

Phase 5: Multi-Session Integration (Anthropic Pattern)

Phase ID: CODITECT-PHASE-5-MULTI-SESSION Status: 📋 READY TO START Priority: P0 - CRITICAL for Production Use Created: 2025-11-29 Estimated Effort: 5-7 hours Based On: Anthropic Multi-Session Claude Agent SDK Pattern (Official)

📋 EXECUTIVE SUMMARY

The Discovery

After completing Phases 1-4 (component activation infrastructure), we discovered that Anthropic has published an official multi-session pattern that solves our exact runtime integration challenge.

Research Document: docs/ANTHROPIC-MULTI-SESSION-PATTERN-RESEARCH.md (8,500 words, 14 sources)

Key Finding: Our infrastructure is 90% aligned with Anthropic's official patterns. We need only 5-7 hours to close the gap and achieve automatic component activation.

Current State (After Phase 4)

What We Built:

✅ ComponentActivator (567 lines) - Loads all 288 components from registries
✅ framework-registry.json (117KB) - Complete component metadata
✅ scripts/init.sh - Environment initialization
✅ MEMORY-CONTEXT/ system - Session preservation
✅ Git-based tracking - Checkpoint system

The Gap:

❌ No automatic component activation on session start
❌ No component-activation-status.json (like Anthropic's feature_list.json)
❌ No session startup workflow
❌ Missing setting_sources configuration for SDK discovery

Target State (After Phase 5)

Multi-Session Workflow (Anthropic Pattern):

User starts Claude Code
↓
Runs: ./scripts/init.sh (auto or manual)
↓
init.sh checks: component-activation-status.json
↓
If not activated → runs activate-all-components.py
↓
Components loaded → 60 agents, all skills, 89 commands available
↓
Claude proceeds with full component knowledge
↓
Session ends → State preserved in activation status
↓
Next session → Resumes from saved state

🎯 ANTHROPIC'S OFFICIAL PATTERN

What Anthropic Uses

feature_list.json - Tracks feature completion across sessions
- JSON format (prevents LLM from modifying it)
- Source of truth for what's implemented
- Only passes field modified by agent
claude-progress.txt - Append-only session log
- Documents what agent did each session
- Enables session orientation ("getting bearings")
- Prevents catastrophic forgetting
init.sh - Environment setup and validation
- Starts development server
- Runs basic tests
- Validates environment ready
setting_sources configuration - Enables component discovery
- setting_sources=["user", "project", "local"]
- Must be explicitly set (not default)
- Required for SDK to find .claude/ components
Two-Agent Pattern - Specialization by session
- Initializer Agent (session 1) - Sets up infrastructure
- Coding Agent (sessions 2+) - Incremental progress

Session Startup Sequence (Official)

pwd - verify working directory
Read state files (claude-progress.txt, feature_list.json)
Read git logs (understand recent work)
Run init.sh (environment validation)
Execute verification tests (ensure system working)
Select work to do (based on state files)

Critical Anthropic Quotes

On JSON vs Markdown:

"We chose JSON because the model is less likely to inappropriately change or overwrite JSON files compared to Markdown files."

On Filesystem Discovery:

"By default, the SDK does not load any filesystem settings." Implication: Must explicitly configure setting_sources

On Session Continuity:

"The key insight here was finding a way for agents to quickly understand the state of work when starting with a fresh context window, which is accomplished with the claude-progress.txt file alongside the git history."

🏗️ IMPLEMENTATION DESIGN

1. component-activation-status.json

Purpose: Track which of 288 components are active (following feature_list.json pattern)

Location: .claude/component-activation-status.json

Schema:

{
  "version": "1.0.0",
  "last_updated": "2025-11-29T10:30:00Z",
  "activation_summary": {
    "total_components": 288,
    "activated": 245,
    "deactivated": 43
  },
  "components": [
    {
      "type": "agent",
      "name": "codi-documentation-writer",
      "path": ".claude/agents/codi-documentation-writer.md",
      "activated": true,
      "activated_at": "2025-11-28T14:20:00Z",
      "reason": "Required for documentation generation"
    },
    {
      "type": "skill",
      "name": "git-workflow-automation",
      "path": ".claude/skills/git-workflow-automation.md",
      "activated": true,
      "activated_at": "2025-11-29T09:15:00Z",
      "reason": "Multi-session git synchronization"
    },
    {
      "type": "command",
      "name": "git-sync",
      "path": ".claude/commands/git-sync.md",
      "activated": false,
      "deactivated_at": "2025-11-27T16:45:00Z",
      "reason": "Debugging incomplete - reactivate after testing"
    }
  ]
}

Key Design Decisions:

JSON format (not YAML) - Prevents accidental LLM modifications
Boolean activated field - Like passes in feature_list.json
Timestamps for audit trail
Reason field for documentation
Summary for quick statistics

2. Enhanced scripts/init.sh

Current Behavior:

Shows git status, test results, progress
Reports component counts (by counting files)
NO component activation

Enhanced Behavior (Phase 5):

#!/bin/bash
# Enhanced init.sh following Anthropic multi-session pattern

echo "=== CODITECT Session Initialization ==="

# 1. Verify working directory
echo "Working directory: $(pwd)"

# 2. Load component activation status
if [ -f ".claude/component-activation-status.json" ]; then
    ACTIVATED_COUNT=$(jq '.activation_summary.activated' .claude/component-activation-status.json)
    TOTAL_COUNT=$(jq '.activation_summary.total_components' .claude/component-activation-status.json)
    echo "✓ Components active: $ACTIVATED_COUNT / $TOTAL_COUNT"
else
    echo "⚠ No activation status - creating..."
    python3 .coditect/scripts/generate-activation-status.py
fi

# 3. Verify critical components activated
python3 .coditect/scripts/verify-critical-components.py

# 4. Git status check
git status --short | head -10

# 5. Activate components based on project type
python3 .coditect/scripts/activate-project-components.py

echo "=== Initialization Complete ==="

3. Session Startup Workflow

New Script: scripts/session-startup.py

#!/usr/bin/env python3
"""
Session Startup Workflow
Follows Anthropic multi-session pattern for component activation
"""

async def initialize_coditect_session():
    """Initialize CODITECT session following Anthropic pattern"""

    # 1. Verify working directory
    cwd = os.getcwd()
    print(f"Working directory: {cwd}")

    # 2. Load component activation status
    activation_file = ".claude/component-activation-status.json"
    if os.path.exists(activation_file):
        with open(activation_file) as f:
            activation_status = json.load(f)
        print(f"Components active: {activation_status['activation_summary']['activated']}")
    else:
        activation_status = generate_initial_activation_status()

    # 3. Read git history for context
    git_log = subprocess.run(
        ["git", "log", "--oneline", "-10"],
        capture_output=True,
        text=True
    ).stdout

    # 4. Load session context from MEMORY-CONTEXT
    latest_session = get_latest_session_export()

    # 5. Run init.sh for environment validation
    subprocess.run(["bash", "scripts/init.sh"], check=True)

    # 6. Configure ClaudeAgentOptions (if SDK available)
    if SDK_AVAILABLE:
        options = ClaudeAgentOptions(
            cwd=cwd,
            setting_sources=["user", "project", "local"],
            allowed_tools=["Skill", "Read", "Write", "Bash"],
        )
        return options, activation_status

    return None, activation_status

4. settings.json Configuration

New: .claude/settings.json

{
  "version": "1.0.0",
  "settingSources": ["user", "project", "local"],
  "allowedTools": [
    "Skill",
    "Read",

    "CODITECT_REGISTRY": "config/framework-registry.json"
  },
  "hooks": {
    "preToolUse": "python3 .coditect/scripts/verify-component-activation.py"
  }
}

Key Settings:

settingSources - Enables SDK to discover .claude/ components
allowedTools - Security allowlist for component types
env - CODITECT environment variables
hooks - Optional validation before tool use

5. Component Activation Management

New Script: scripts/update-component-activation.py

def update_component_activation(component_name, activated, reason):
    """
    Update component activation status with timestamp and reason.
    Follows pattern of feature_list.json with controlled modifications.
    """

    status_file = ".claude/component-activation-status.json"

    with open(status_file, 'r') as f:
        status = json.load(f)

    # Find component
    for component in status['components']:
        if component['name'] == component_name:
            # Only modify activation fields
            component['activated'] = activated
            component['activated_at' if activated else 'deactivated_at'] = now()
            component['reason'] = reason
            break

    # Update summary counts
    status['activation_summary']['activated'] = sum(
        1 for c in status['components'] if c['activated']
    )
    status['last_updated'] = now()

    # Save atomically
    atomic_write(status_file, status)

    # Git commit the change
    git_commit(f"{'Activate' if activated else 'Deactivate'} component: {component_name}")

Anthropic Sources

📝 NOTES & ASSUMPTIONS

Assumptions

Claude Code SDK available - settingSources configuration will work
JSON format preferred - Following Anthropic's reasoning (prevents LLM modification)
jq installed - Required for init.sh JSON parsing (fallback to Python if not)
Git repository - Required for activation tracking
Python 3.10+ - Required for type hints and modern features

Known Limitations

Manual init.sh execution - User must run ./scripts/init.sh at session start
- Mitigation: Add to session startup docs, create alias
- Future: Investigate automatic execution via hooks
SDK integration optional - Works without Claude Agent SDK
- Mitigation: Graceful degradation if SDK not available
- Future: Full SDK integration when available
Component activation granularity - All-or-nothing per component
- Mitigation: Sufficient for v1, enhancement for v2
- Future: Partial activation (specific capabilities)

Dependencies

Internal:

Phase 4 must be complete (ComponentActivator operational)
framework-registry.json must exist and be valid
scripts/init.sh must exist

External:

jq for JSON parsing in bash (optional, Python fallback)
Git for activation tracking
Claude Code for settings.json integration (optional)
