ckb

Overview

CKB transforms codebases into queryable knowledge bases, offering semantic search, call graphs, impact analysis, and architecture mapping. It provides compound operations that reduce AI tool calls by 60-70% and integrates with AI assistants like Claude Code, Cursor, and Windsurf via MCP. The system supports multiple interfaces including CLI, HTTP API, and MCP, with language support for Go, TypeScript, JavaScript, Python, and more.

Try asking AI

After installing, here are 5 things you can ask your AI assistant:

• explore

  Area exploration: finds symbols, dependencies, and hotspots in a code area

  Try:Explore the checkout moduleTry:What's in the API directory?
• understand

  Symbol deep-dive: finds references, callers, and explanations for a specific symbol

  Try:Understand the ProcessPayment functionTry:Explain the UserService class
• prepareChange

  Pre-change analysis: determines impact, affected tests, and risk of changing code

  Try:What's the impact of changing the User model?Try:Prepare for changing the API endpoint
• batchGet

  Fetch up to 50 symbols at once for efficient bulk operations

  Try:Get details for these 10 functionsTry:Fetch information about classes A, B, and C
• batchSearch

  Run up to 10 searches at once to reduce API overhead

  Try:Search for 'handler', 'request', and 'response'Try:Find all tests related to authentication
• findReferences

  Find all references to a specific symbol in the codebase

  Try:Where is the HandleRequest function used?Try:Who calls the ProcessPayment method?
• searchSymbols

  Search for symbols by name with semantic understanding

  Try:Find all handler functionsTry:Search for classes with 'Service' in the name
• hotspots

  Identify risky areas in the codebase based on complexity, coupling, and change frequency

  Try:Show me the riskiest code areasTry:What parts of the codebase are hotspots?
• architecture

  Generate architecture overview and module dependencies

  Try:Show me the system architectureTry:How are the modules organized?
• ownership

  Find code ownership and reviewer suggestions based on CODEOWNERS and git history

  Try:Who owns the authentication module?Try:Who should review this API change?
• findDeadCode

  Detect unused code with confidence scores based on call graphs and references

  Try:Find dead code in the utilities directoryTry:What parts of the codebase are unused?
• compareAPI

  Analyze API changes between versions to identify breaking changes and affected clients

  Try:What's different between v1 and v2 of the API?Try:Check for breaking changes in this PR
