🧠 Mini-CoderBrain

Universal AI Context Awareness System for Claude Code

Transform Claude from a stateless assistant into a persistent, context-aware development partner in 30 seconds.

🎯 The Problem We Solve

Have you ever experienced this with Claude Code?

❌ Context Amnesia

Start a new conversation → Claude asks "What framework are you using?" (for the 10th time)
Explain your project structure again and again
Re-describe your coding conventions every session
Lost progress tracking between sessions

❌ "Prompt is too long" Errors

Working fine, then suddenly conversation breaks
Can't continue your work mid-feature
Lose entire conversation context
Start over from scratch

❌ Inefficient Development

Waste 5-10 minutes every session explaining context
Claude doesn't remember architectural decisions
No visibility into what Claude is actually doing
Manual progress tracking across sessions

❌ Lack of Project Understanding

Claude can't find files without explicit paths
Doesn't understand your tech stack automatically
Asks basic questions about your setup repeatedly
No awareness of project-specific patterns

✅ How Mini-CoderBrain Fixes This

Perfect Memory

Claude remembers your entire project across all sessions
Zero repeated explanations
Automatic project structure detection
Persistent technical decisions

Never Hit Token Limits

Intelligent memory cleanup prevents "Prompt too long"
79.9% token efficiency improvement
25% longer conversations
Work for hours without interruption

Instant Productivity

30-second setup, zero configuration
Claude starts coding immediately
No wasted time on context
Real-time activity tracking

Complete Project Awareness

Knows your tech stack automatically
Understands file locations instantly
Follows your coding patterns
Tracks progress across sessions

⚡ Quick Start (2 Minutes)

Step 1: Install Mini-CoderBrain

# 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

Step 2: Initialize Context (MANDATORY)

⚠️ 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

Step 3: Choose Your Profile (v2.1 - OPTIONAL)

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).

Step 4: Verify Setup

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!

Method 2: Manual Install (Fallback)

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

Verification

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!

🎯 Core Features

1. Real-Time Activity Tracking ✨

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

2. Intelligent Notifications ✨

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

3. Mandatory Pre-Response Protocol ✨

Claude MUST complete this checklist before responding:

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

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

4. Zero Context Duplication

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)

5. Intelligent Memory Cleanup

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!

6. Perfect Cross-Session Continuity

Claude remembers:

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

📚 Available Commands

Essential Commands (Use These!)

📖 Full Command Documentation: See docs/commands.md

🛠️ How It Works

Hook System

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

Status Footer Display

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
