CKB 8.0: Compound Operations, 80+ Tools, and Our New Website

By CKB Team

Today marks a major milestone for CKB. We're launching version 8.0 alongside our brand new website at codeknowledge.dev. This release focuses on making AI-assisted development faster, more reliable, and more efficient.

What's New in CKB 8.0

Compound Operations: 60-70% Fewer AI Tool Calls

The headline feature of 8.0 is compound operations. These are smart aggregation tools that combine multiple queries into single, optimized calls.

Instead of your AI assistant making 5 sequential tool calls to understand a symbol, it now makes 1:

  • explore - Area exploration combining file explanation, symbol search, call graphs, and hotspot detection
  • understand - Symbol deep-dive with references, callers, callees, and AI explanation
  • prepareChange - Pre-change impact analysis with affected tests and risk assessment
  • batchGet - Fetch up to 50 symbols in a single call
  • batchSearch - Run up to 10 searches at once

This dramatically reduces latency and token overhead when working with AI coding assistants.

80+ MCP Tools

CKB now offers over 80 tools via the Model Context Protocol, organized into smart presets:

Preset Tools Use Case
core 14 Essential navigation and impact
review 19 Code review with ownership
refactor 19 Coupling and dead code analysis
federation 28 Cross-repo queries
full 80+ All tools

The default core preset uses only ~1.5k tokens while giving your AI access to the most important capabilities. You can expand mid-session using the expandToolset tool.

SSE Streaming for Long Operations

Large codebases can have thousands of references to popular symbols. With 8.0, tools like findReferences and searchSymbols now support Server-Sent Events streaming, giving you real-time progress updates instead of waiting for the complete result.

Structured Errors with Remediation

When something goes wrong, CKB 8.0 tells you exactly what happened and how to fix it. Six error categories with clear remediation guidance replace cryptic failure messages.

Confidence Scoring

Every result now includes a confidence tier (high, medium, or low) with explanations. Know when to trust the analysis and when to verify manually.

Our New Website

We've built codeknowledge.dev from the ground up to help you get the most out of CKB:

  • Features - Detailed documentation for all 80+ tools across 9 categories
  • Prompt Cookbook - Real prompts for real problems, ready to copy
  • Documentation - Comprehensive guides from quick start to advanced federation
  • Pricing - Free for personal use, simple pricing for teams

Getting Started

Install CKB and connect it to your AI assistant in under a minute:

npm install -g @tastehub/ckb
cd /your/project
ckb init
ckb setup

Your AI coding assistant now has deep understanding of your codebase. Try asking:

  • "What calls the HandleRequest function?"
  • "What's the blast radius if I change UserService?"
  • "Who should review changes to the auth module?"

What's Next

We're already working on CKB 8.1 with improved test mapping, coverage configuration, and orphaned index detection. Follow our changelog for updates.

Thank you for being part of the CKB community. We can't wait to see what you build.
