description	Create repository context bundles and code maps. Use to share codebase context, generate documentation, and understand project structure.

Repository Context

Generate context bundles and maps for codebases.

Structure Analysis

Quick Structure

# Tree view (basic)
tree -L 2 -I 'node_modules|.git|dist|build'

# With file counts
tree -L 2 -I 'node_modules|.git' --dirsfirst -C

# Just directories
tree -d -L 3 -I 'node_modules|.git'

Detailed Structure

#!/bin/bash
# repo-structure.sh

echo "# Repository Structure"
echo ""
echo "## Root Files"
ls -la | grep "^-" | awk '{print "- " $NF}'

echo ""
echo "## Directories"
for dir in */; do
  if [[ "$dir" != "node_modules/" && "$dir" != ".git/" ]]; then
    echo "### $dir"
    ls -la "$dir" | head -10
    echo ""
  fi
done

Code Maps

Generate Code Map

#!/bin/bash
# codemap.sh - Generate code map

echo "# Code Map"
echo ""

# Find all source files
find src -name "*.ts" -o -name "*.tsx" | while read file; do
  echo "## $file"
  echo '```typescript'

  # Extract exports
  grep -E "^export (function|const|class|interface|type)" "$file" | head -20

  echo '```'
  echo ""
done

Function Index

# List all exported functions
grep -rh "^export function" src/ | sort

# With file locations
grep -rn "^export function" src/ | sort

Class Index

# List all classes
grep -rn "^export class" src/ | sort

# With methods
grep -rh "^export class\|^\s*\(async \)\?[a-z]\+(" src/ | head -50

Context Bundles

Create Bundle for AI

#!/bin/bash
# bundle-context.sh - Create context for AI

OUTPUT="CONTEXT.md"

cat > $OUTPUT << 'EOF'
# Repository Context

## Project Overview
EOF

# Add package.json summary
if [ -f package.json ]; then
  echo '```json' >> $OUTPUT
  jq '{name, description, main, scripts: .scripts | keys}' package.json >> $OUTPUT
  echo '```' >> $OUTPUT
fi

# Add key files
echo "" >> $OUTPUT
echo "## Key Files" >> $OUTPUT

for file in src/index.ts src/main.ts app.ts; do
  if [ -f "$file" ]; then
    echo "" >> $OUTPUT
    echo "### $file" >> $OUTPUT
    echo '```typescript' >> $OUTPUT
    head -100 "$file" >> $OUTPUT
    echo '```' >> $OUTPUT
  fi
done

 

Smart Pack (Key Files Only)

#!/bin/bash
# smart-pack.sh - Pack only important files

# Identify key files
KEY_PATTERNS=(
  "package.json"
  "tsconfig.json"
  "src/index.ts"
  "src/main.ts"
  "README.md"
)

for pattern in "${KEY_PATTERNS[@]}"; do
  if [ -f "$pattern" ]; then
    echo "=== $pattern ==="
    cat "$pattern"
    echo ""
  fi
done

Import Analysis

Dependency Graph

# Find what imports what
grep -rh "^import.*from" src/ | \
  sed "s/.*from ['\"]//; s/['\"].*//" | \
  sort | uniq -c | sort -rn | head -20

External Dependencies

# Most used external packages
grep -rh "^import.*from ['\"]" src/ | \
  grep -v "from ['\"]\./" | \
  sed "s/.*from ['\"]//; s/['\"].*//" | \
  sort | uniq -c | sort -rn

Internal Module Graph

# Internal imports
grep -rh "^import.*from ['\"]\./" src/ | \
  sed "s/.*from ['\"]//; s/['\"].*//" | \
  sort | uniq -c | sort -rn

AI-Powered Analysis

Architecture Summary

STRUCTURE=$(tree -L 2 -I 'node_modules|.git' --dirsfirst)
PACKAGE=$(cat package.json 2>/dev/null)

gemini -m pro -o text -e "" "Analyze this repository structure:

Structure:
$STRUCTURE

package.json:
$PACKAGE

Provide:
1. Architecture pattern used
2. Main entry points
3. Key modules and their purpose
4. Dependencies overview
5. Suggested improvements"

Code Quality Overview

# Get sample of files
SAMPLES=$(find src -name "*.ts" | head -5 | xargs cat)

gemini -m pro -o text -e "" "Review code quality:

$SAMPLES

Assess:
1. Code organization
2. Naming conventions
3. Error handling
4. Type safety
5. Suggestions"

Documentation Generation

Auto README

gemini -m pro -o text -e "" "Generate a README for this project:

package.json:
$(cat package.json)

Main file:
$(cat src/index.ts | head -100)

Include:
- Description
- Installation
- Usage
- API overview
- Contributing"

API Documentation

# Extract all exports
EXPORTS=$(grep -rh "^export" src/ | head -50)

gemini -m pro -o text -e "" "Generate API documentation for:

$EXPORTS

Format as markdown with:
- Function signatures
- Parameter descriptions
- Return types
- Example usage"

Best Practices

1. Ignore noise - Exclude node_modules, .git, build
2. Focus on entry points - Start with main files
3. Track dependencies - Understand what's imported
4. Use AI for summaries - Large codebases need synthesis
5. Keep bundles updated - Regenerate after major changes
6. Share context - Help others understand quickly
