## 🎯 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

## ⚡ Quick Start (2 Minutes)



### Step 1: Install Mini-CoderBrain



```bash

# 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!



```bash

# 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:



```yaml

# 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:



```bash

/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:



```bash

# 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**:



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?"



### 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!)



| Command | Purpose | When to Use |

|---------|---------|-------------|

| `/init-memory-bank` | **Initialize context (MANDATORY)** | After installation, before anything else |

| `/validate-context` | Check context quality | After init, or when Claude seems confused |

| `/update-memory-bank` | Update memory after work | After major features/decisions |

| `/map-codebase` | Enable instant file access | Once per project, rebuild when stale |

| `/memory-cleanup` | Archive old data | When notified (prevents "Prompt too long") |



### Advanced Commands



| Command | Purpose | When to Use |

|---------|---------|-------------|

| `/import-docs` | Import external documentation | When you have SRS/Architecture docs |

| `/memory-sync` | Full memory bank sync | Comprehensive analysis needed |

| `/context-update` | Quick real-time updates | During active development |



**📖 Full Command Documentation**: See [docs/commands.md](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
