@01b/team-kb

CLI tool for building and wiring a Team Knowledge Base (KB) so that LLMs (Claude, Gemini, Codex) can automatically leverage shared team knowledge.

Why

• LLM sessions reset every time. Domain knowledge explained yesterday is forgotten today.
• Knowledge stays siloed — what one developer teaches Claude, another's Gemini doesn't know.
• LLMs ignore team coding conventions because they don't know they exist.

@01b/team-kb solves this by creating a shared, git-based knowledge base that automatically loads into any LLM tool across your team.

How is this different from RAG? RAG searches documents when you ask. team-kb pre-loads knowledge into every LLM session — your LLM already knows your domain before you ask anything. Learn more

Install

npm install -g @01b/team-kb

Commands

kb init

Create a new KB repository. Run once per team.

mkdir ~/team-kb && cd ~/team-kb
kb init

kb join <url>

Join an existing KB. Run once per team member.

kb join https://github.com/your-org/team-kb.git

This will:

• git clone the KB repository
• Install the pre-commit hook
• Save the KB path to local config

kb wire <tool>

Wire a project to the KB. Run once per project per tool.

cd ~/repos/my-project
kb wire claude    # Claude Code
kb wire gemini    # Gemini CLI
kb wire codex     # Codex CLI

Claude

Creates symlinks in .claude/rules/ pointing to KB files. Claude Code auto-scans this directory, so KB rules and knowledge are loaded automatically every session.

Gemini

Creates GEMINI.md with @import chain via .gemini/kb-context/ symlink. Gemini loads GEMINI.md as a foundational mandate, which imports KB rules and knowledge through the symlink.

Codex

Creates AGENTS.md with a directive to read .codex/kb-directive.md. Codex reads AGENTS.md on session start and follows the instruction to load KB content via tool calls.

How wiring works

Claude:  .claude/rules/ ── auto-scan ──→ symlinks ──→ KB ai-context/
Gemini:  GEMINI.md ──@import──→ kb-import.md ──@import──→ kb-context/ (symlink) ──→ KB ai-context/
Codex:   AGENTS.md ──directive──→ kb-directive.md ──tool call──→ KB ai-context/

Tracked vs local-only: Tracked files (git commit) contain only KB entry points. Files with absolute paths are local-only (.gitignore) to prevent path conflicts between team members.

kb index

Rebuild the KB search index. Uses Node.js for safe JSON serialization (replaces the legacy bash script).

kb index           # Rebuild kb-index.json
kb index --check   # Validate frontmatter without rebuilding

Runs automatically via the pre-commit hook on every commit.

kb query <keywords>

Search the KB from the command line. Designed for LLM tool calls — one command returns matching notes.

kb query "coupon discount"              # OR matching, top 5, tldr + first 30 lines
kb query "coupon" --repo my-service     # Prioritize notes tagged with repo/my-service
kb query "redis" --brief                # Show tldr only (note list)
kb query "cache" --full                 # Show full note content
kb query "coupon" --limit 3             # Top 3 results only

LLMs use this automatically via the rules in ai-context/kb-rules.md.

Recording Knowledge

While working with an LLM, when you discover new domain knowledge:

"Record this to KB"

The LLM will:

1. Determine the appropriate folder based on content type
2. Create a note with proper frontmatter (tags, tldr, created, updated)
3. The pre-commit hook automatically rebuilds the search index on commit

Tag namespaces

Tags use / as a namespace separator (Obsidian-compatible):

tags: [repo/my-service, domain/coupon, tech/redis]

Folder guide

KB Search Rules

Defined in ai-context/kb-rules.md and auto-loaded into every LLM session:

• KB first — For domain knowledge questions, check KB before searching code
• Code is truth — KB is a guide, code is the source of truth. Lightly verify against code when answering about code behavior
• Mismatch handling — If KB and code disagree, answer based on code + report the mismatch + suggest KB update
• Efficient search — LLMs use kb query for fast single-command KB search

Trust Hierarchy

Works with Obsidian

The KB is a plain folder of markdown files with YAML frontmatter — Obsidian reads it natively as a vault. Tags use / separator, which Obsidian renders as a navigable tree in the tag panel. Obsidian CLI (v1.12+) can also be used to search and manage KB notes from the terminal.
