What Happens Behind the Scenes

Persona Commands (/fb:persona architect "review API"):

1. Direct template application: Reads persona template from .claude/flashback/personas/architect.md
2. Simple output: Template content + your request in current conversation
3. Immediate analysis: No subagent spawn, direct analysis

Agent Commands (@agent-architect "review API"):

1. Agent spawning: Claude Code spawns dedicated architect subagent
2. Context gathering: Agent runs flashback agent --context to get project bundle
3. Rich context: Agent receives REMEMBER.md, WORKING_PLAN.md, conversation history
4. Project-aware analysis: Specialized analysis with full project understanding

Session Management (Manual - No Automatic Hooks):

• When context window hits ~10%, run /fb:save-session or /fb:working-plan
• After compaction, run /fb:session-start to restore context
• Memory files: REMEMBER.md, WORKING_PLAN.md, CURRENT_SESSION.md

✨ Core Features

🧠 Session Continuity System (Manual)

• Manual Memory Management: Claude Code lacks pre/post-compaction hooks
• Memory Injection: REMEMBER.md prevents repeated corrections across sessions
• Working Plan Intelligence: AI analyzes conversations to update development plans
• Session Restoration: /fb:session-start restores context after compaction

🎭 Dual-Layer AI System

• /fb:persona architect "analyze API design" - Direct template application
• All 20 personas available for immediate analysis in current conversation

Layer 2: Agents (Dedicated Subagents)

• @agent-architect "analyze API design" - Spawns dedicated subagent with full project context
• Agents automatically gather context via flashback agent --context

Session Management

/fb:working-plan          # Update development plan with AI analysis
/fb:save-session         # Capture session insights before compaction
/fb:session-start        # Load project context (runs automatically via hook)
/fb:how                  # Implementation planning prompt (plan before coding)
/fb:how "specific topic"         # Focused planning for specific topic only
/fb:remember important insight here  # Add key information to project memory
/fb:persona-list         # Show all available AI personas with descriptions
/fb:agents-list          # Show all available Claude Code agents with descriptions

# Automatically detects and analyzes:
# - JavaScript/TypeScript: console.log(), debugger;, empty functions
# - Python: print(), pdb.set_trace(), NotImplementedError
# - Go: fmt.Println(), panic(), runtime.Breakpoint()
# - Java: System.out.println(), UnsupportedOperationException
# - Rust: println!(), panic!(), unimplemented!()
# - Universal patterns: TODO comments, generic names, similar functions

Memory Management

# Add key information to project memory:
/fb:remember important architectural decision about database design

# View current project memory:
flashback memory --show

🏗️ How It Works

1. Installation & Setup

• Run flashback init --mcp once per project (recommended)
• Creates .claude/flashback/ directory structure
• Installs SessionStart hook for automatic context loading
• Configures powerful MCP servers for enhanced capabilities

2. Daily Usage

• Use /fb:persona <name> "request" for specialized analysis
• Use /fb:working-plan to keep development priorities current
• Use /fb:save-session before major context compactions
• Memory automatically loads via SessionStart hook

3. Behind the Scenes

• CLI: Gathers project context, loads templates, formats prompts
• Claude: Executes Task tool with specialized persona prompts
• Hybrid Pattern: Computer handles data, AI handles intelligence

🔧 Advanced Features

Discussion System

# CLI command for multi-agent analysis (READ ONLY recommended):
flashback discuss "Should we use microservices?" john-carmack,architect,devops,security

# In-conversation multi-agent discussions:
/fb:discuss architect,security,performance "review this authentication implementation"

Diagnostics (When Things Go Wrong)

flashback doctor          # Check system health
flashback status          # Verify installation
flashback init --refresh  # Update templates
flashback init --mcp      # Add MCP servers to existing setup

🏗️ Architecture

Template-Driven System

• Dynamic Directory Scanning: Reads bundled templates at runtime
• Zero Hardcoded Paths: All structure derived from template bundle
• Variable Replacement: {{PROJECT_NAME}}, {{VERSION}}, {{TIMESTAMP}}
• Version Sync: Automatically uses package.json version

Hybrid AI+Computer Operations

• CLI: Handles programmatic operations (file management, data extraction)
• AI: Handles intelligence operations (analysis, planning, decisions)
• Clear Separation: Computer does deterministic work, AI does creative work

🔧 Requirements

• Node.js 18.x-22.x LTS: Required for tree-sitter native modules and modern features
• npm 9.x+: Required for lockfile version 3 support
• Claude Code: Latest version for hook system compatibility

⚠️ Note: Versions outside the Node.js 18-22 range may cause native module compilation errors.
