# Clone the repository
git clone https://github.com/kunwar-shah/mini-coder-brain.git
cd mini-coder-brain
# Run installer
chmod +x install.sh
./install.sh /path/to/your/project

⚠️ CRITICAL: This step is REQUIRED for mini-coder-brain to work!

# Open your project in Claude Code
cd /path/to/your/project
# Run mandatory initialization (CHOOSE ONE):
# Option A: If you have documentation (RECOMMENDED)
/init-memory-bank --docs-path ./docs
# Option B: Auto-detect from code (existing projects)
/init-memory-bank
# Option C: Interactive wizard (new projects)
/init-memory-bank

What this does:

• 🔍 Detects your project type automatically
• 📚 Reads your documentation (if provided)
• 🎯 Populates all memory bank files with real data
• ✅ Validates context quality (shows percentage score)
• 🚀 Makes Claude 100% context-aware immediately

Customize Claude's behavior for your task:

# Edit CLAUDE.md (line ~41):
behavior_profile: "default" # default / focus / research / implementation

Profile Options:

• default - Balanced general development (recommended)
• focus - Deep concentration, minimal output
• research - Detailed exploration and learning
• implementation - Rapid feature building

Skip this step to use default profile (works like v2.0).

Check your context quality:

/validate-context

Expected output:

📊 Context Quality: 85% (Recommended) ✅
🎭 Profile: default
✅ Ready for development!

Done! Claude now knows your entire project with customizable behavior!

If the automatic installer fails, use this manual method:

# 1. Clone the repository
git clone https://github.com/kunwar-shah/mini-coder-brain.git
cd mini-coder-brain
# 2. Copy framework files to your project
cp -r .claude /path/to/your/project/
cp CLAUDE.md /path/to/your/project/
# 3. Initialize memory bank from templates
cd /path/to/your/project
cp .claude/memory/templates/productContext-template.md .claude/memory/productContext.md
cp .claude/memory/templates/activeContext-template.md .claude/memory/activeContext.md
cp .claude/memory/templates/progress-template.md .claude/memory/progress.md
cp .claude/memory/templates/decisionLog-template.md .claude/memory/decisionLog.md
cp .claude/memory/templates/systemPatterns-template.md .claude/memory/systemPatterns.md
# 4. Make hooks executable
chmod +x .claude/hooks/*.sh
# Done! Open Claude Code in your project

After installation, start Claude Code. You should see:

🧠 [MINI-CODERBRAIN: ACTIVE] - YourProjectName
🎯 Focus: General Development
📂 Context: .claude/memory/ (loaded)
🎭 Profile: default
⚡ Ready for development | Session: sessionstart-1234567890

And at the end of every response:

🧠 MINI-CODERBRAIN STATUS
📊 Activity: 15 ops | 🗺️ Map: None | ⚡ Context: Active
💡 [Intelligent notifications appear here when needed]

Success! Claude now has full project context and real-time status!

What it does:

• Tracks every tool use (Read, Write, Edit, Bash, Glob, Grep)
• Displays accurate operation counts
• Shows in status footer: 📊 Activity: 42 ops

How it works:

• PostToolUse hook logs every operation
• Daily log files: .claude/memory/conversations/tool-tracking/YYYY-MM-DD-tools.log
• Instant visibility into your workflow

Smart alerts for:

• 🧹 Memory Bloat: When activeContext.md exceeds 10 session updates or 200 lines
• 🗺️ Map Staleness: When codebase map is >24 hours old
• 🔄 High Activity: When >50 operations detected (with time-based reminders)

Example:

🧠 MINI-CODERBRAIN STATUS
📊 Activity: 58 ops | 🗺️ Map: Stale (26h) | ⚡ Context: Active
💡 🔄 High activity (58 ops) + 3h since last sync. Run /memory-sync --full.
💡 🗺️ Codebase map is 26h old. Suggest: /map-codebase --rebuild

Claude MUST complete this checklist before responding:

1. ✅ CHECK productContext.md → Project name, tech stack, architecture
2. ✅ CHECK systemPatterns.md → Coding patterns, conventions, standards
3. ✅ CHECK activeContext.md → Current focus, recent work
4. ✅ CHECK project-structure.json → File locations
5. ✅ CHECK codebase-map.json → Specific file paths (if mapped)

Result: 90% fewer redundant questions like "What framework are you using?"

Problem Solved: Previous versions re-injected context every turn, causing token bloat.

Solution:

• Context loaded ONCE at session start
• Persists naturally in conversation history
• Zero re-injection = 79.9% token savings
• Result: 25% longer conversations (80 → 100+ turns)

Problem Solved: Memory bank grows indefinitely, causing "Prompt is too long" errors.

Solution:

• Auto-detects memory bloat (>10 session updates)
• Notifies: 🧹 Run /memory-cleanup
• Archives old data (keeps last 5 sessions)
• Result: 60% memory reduction, infinite sessions!

Claude remembers:

• ✅ Your project structure and architecture
• ✅ Recent development progress
• ✅ Active blockers and priorities
• ✅ Technical decisions made
• ✅ Coding patterns and standards

📖 Full Command Documentation: See docs/commands.md

Session Start
 ↓
session-start.sh loads all memory bank files
 ↓
User sends message
 ↓
UserPromptSubmit hook builds status + notifications
 ↓
PostToolUse hook tracks every operation
 ↓
Claude displays status footer (per CLAUDE.md)
 ↓
Stop hook updates activeContext.md on session end

The status footer appears at the END of every Claude response:

🧠 MINI-CODERBRAIN STATUS
📊 Activity: X ops | 🗺️ Map: Status | ⚡ Context: Active
💡 [Notifications only shown when triggered]

This keeps you informed about:

• How many operations have been performed
• Whether your codebase map is fresh or stale
• System state and health
• Proactive suggestions for optimization
