Kibi is a repo-local, per-git-branch, queryable knowledge base for software projects. It stores requirements, scenarios, tests, architecture decisions, and more as linked entities, ensuring end-to-end traceability between code and documentation.

Why Kibi

Kibi is designed to boost AI agents' memory during software development. It maintains a living, verifiable project memory that:

• Tracks context across branches — Every git branch gets its own KB snapshot, preserving context as you switch between features
• Enforces traceability — Links code symbols to requirements, preventing orphan features and technical debt
• Validates automatically — Rules catch missing requirements, dangling references, and consistency issues
• Agent-friendly — LLM assistants can query and update knowledge base via MCP without risking file corruption

What You Get

Kibi provides concrete, day-to-day benefits for developers and teams:

• Requirements Traceability — Track every code symbol back to its requirement. Know why code exists and what business need it addresses.

• Test Coverage Visibility — See which requirements have tests, which don't, and what's covered at a glance. Ensure nothing slips through the cracks.

• Architectural Constraints — Link code to ADRs. Know what constraints apply to each symbol and verify architecture decisions are honored.

• Feature Flag Blast Radius — See what code depends on a runtime/config gate before toggling it. Understand the impact of enabling or disabling a feature.

• Event-Driven Architecture — Map who publishes and consumes each domain event. Trace event flows and identify couplings across the system.

• Branch-Local Memory — Every git branch keeps its own KB snapshot. Switch contexts without losing traceability or polluting other branches.

For OpenCode users, bootstrap an existing repo with /init-kibi.

Entity Modeling Note: Use flag for runtime/config gates only. Document bugs and workarounds as fact entities with fact_kind: observation or meta. See Entity Schema and AGENTS.md for the canonical guidance.

Key Components

• kibi-core — Prolog-based knowledge graph that tracks entities across branches
• kibi-cli — Command-line interface for automation and hooks
• kibi-mcp — Model Context Protocol server for LLM integration
• kibi-opencode — OpenCode plugin that injects Kibi guidance and runs background syncs
• kibi-vscode — VS Code extension for exploring the knowledge base

Prerequisites

• SWI-Prolog 9.0+ — Kibi's knowledge graph runs on Prolog

Installation

Kibi supports two common setups:

• Global install for normal use across repositories
• Repo-local dogfood workflow in this repository, where OpenCode and MCP use locally built artifacts

# Using npm (recommended)
npm install -g kibi-cli kibi-mcp

# Using bun
bun add -g kibi-cli kibi-mcp

After installation, verify that kibi is available:

kibi --version

OpenCode Plugin

Add kibi-opencode to your project opencode.json:

{
  "$schema": "https://opencode.ai/config.json",
  "plugin": ["kibi-opencode"]
}

OpenCode installs npm plugins declared in plugin automatically at startup.

VS Code Extension

The Kibi VS Code extension provides a TreeView explorer for your knowledge base and built-in MCP integration.

Download the latest .vsix from GitHub Releases, then install it:

• Command Palette: Ctrl+Shift+P → Extensions: Install from VSIX... → select the file
• CLI: code --install-extension kibi-vscode-x.x.x.vsix

Every GitHub release includes the latest VS Code extension build as a .vsix artifact.

Repo-local dogfood workflow (this repo)

This repository uses local built kibi-mcp and kibi-opencode artifacts during development. If you change package versions or local package wiring used by the OpenCode setup here, rebuild before testing:

bun run build

VS Code MCP

Create .vscode/mcp.json:

{
  "servers": {
    "kibi": {
      "type": "stdio",
      "command": "kibi-mcp"
    }
  }
}

If kibi-mcp is not on your PATH, replace command with the full executable path.

For complete installation steps and SWI-Prolog setup, see detailed installation guide.

Quick Start

Initialize kibi in your repository:

# Verify environment prerequisites
kibi doctor

# Initialize .kb/ and install git hooks
kibi init

# Parse markdown docs and symbols into branch KB
kibi sync

# Discover relevant knowledge before exact lookups
kibi search auth

# Inspect current branch snapshot and freshness
kibi status

# Run integrity checks
kibi check

Note: kibi init installs git hooks by default. Hooks automatically sync your KB on branch checkout and merge.

Typical discovery workflow

# Explore the KB first
kibi search login

# Then follow up with exact/source-linked queries
kibi query req --source src/auth/login.ts --format table

# Check branch attachment and freshness when needed
kibi status

# Ask focused reporting questions
kibi gaps req --missing-rel specified_by,verified_by --format table
kibi coverage --by req --format table

Release and Versioning

All publishable npm packages in this repo (kibi-core, kibi-cli, kibi-mcp, kibi-opencode) follow the same Changesets workflow for versioning and changelog generation.

# Add release metadata for changed package(s)
bun run changeset

# Preview pending releases
bunx changeset status

# Apply version bumps and update package changelogs
bun run version-packages

---

⚠️ Alpha Status: Kibi is in early alpha. Expect breaking changes. Pin exact versions of kibi-cli, kibi-mcp, and kibi-opencode in your projects, and expect to occasionally delete and rebuild your .kb folder when upgrading.
