kb-init is a skill for Claude Code from charlesjones-dev/claude-code-plugins-dev. It costs 32 tokens per session (2,903 once invoked), scanned A, original, MIT.

A setup tool for a project's knowledge base, which is a collection of reusable team notes and documentation. It creates the documentation folder and adds or updates its reference section in CLAUDE.md.

In plain words
What is it for?
Starting a knowledge base, creating its directory, registering it in CLAUDE.md, and checking whether an existing setup is already present.
Why use it?
It gives a project a consistent place and configuration for shared technical knowledge, while allowing the setup to be run again safely.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

kb-init scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Knowledge Base Initialization

You are a knowledge base setup assistant. Your job is to initialize the Knowledge Base infrastructure in the current project.

Instructions

CRITICAL: This command MUST NOT accept any arguments. Ignore any text provided after the command.

SCOPE RULE: All KB operations target only the current working directory (the parent directory where Claude Code is running). Never create docs/kb/ in subdirectories, never modify CLAUDE.md files in subdirectories, and never add KB references to sub-directory CLAUDE.md files. The docs/kb/ directory and its contents should be committed to source control for team sharing.

Step 1: Detect Current State

  1. Check for docs/kb/ directory: Use Glob to check if docs/kb/ exists and contains any .md files.
  2. Check for CLAUDE.md: Read the project's CLAUDE.md file (in the current working directory). If it doesn't exist, note that it will be created.
  3. Check for existing KB section: If CLAUDE.md exists, look for a ## Knowledge Base section (or # Knowledge Base depending on heading conventions used in the file).

Step 2: Create Directory Structure

Resolve today's date (cross-platform, CRITICAL): Before writing any file below, run the first command that works in the current shell and use the returned YYYY-MM-DD string for every {today's date} placeholder in the templates. Never guess, never infer, never increment.

  • macOS / Linux / WSL / Git Bash (bash, zsh, sh): date +%Y-%m-%d
  • Windows PowerShell / pwsh: Get-Date -Format 'yyyy-MM-dd'
  • Windows cmd.exe: powershell -NoProfile -Command "Get-Date -Format 'yyyy-MM-dd'"
  • Portable fallback (Node or Python available): node -e "console.log(new Date().toISOString().slice(0,10))" or python -c "import datetime; print(datetime.date.today().isoformat())"

If docs/kb/ does not exist, create it with a placeholder README:

File: docs/kb/README.md

# Knowledge Base

This directory contains topic-specific knowledge base files that are dynamically referenced in CLAUDE.md.

## Structure

KB articles are organized in category folders. Special files (prefixed with `_`) live at the root:

docs/kb/ _global-learnings.md # Cross-cutting rules (pinned, always loaded) _index.md # Auto-generated page catalog with summaries _log.md # Chronological operation log README.md # This file architecture/ # Architecture patterns and system design conventions/ # Naming, coding, and API conventions tools/ # Tooling, workflow, and infrastructure ... # Other categories as needed


Category folders are created as needed based on article content. Articles can also be flat at the root for small KBs:

## Frontmatter Schema

Every KB file MUST include YAML frontmatter. This metadata is used by all `/kb-*` commands for search, pruning, cross-referencing, and contextual loading.

```yaml
---
tags: [api, auth, security]          # Cross-cutting topic tags for discovery
related: [[api-conventions]]         # Cross-references to other KB files (by filename without extension)
created: 2026-04-02                  # Date the file was created
last-updated: 2026-04-02            # Date the file was last modified
pinned: false                        # If true, always loaded regardless of context
scope: "packages/api/**"             # Optional glob pattern(s) for auto-matching. String or array of strings.
---

Field Reference

Field Required Description
tags Yes Array of lowercase tags for cross-cutting discovery. Used by /kb-search.
related No Array of [[filename]] references to other KB files. When one file is loaded, related files may also be consulted.
created Yes ISO date (YYYY-MM-DD) when the file was first created.
last-updated Yes ISO date (YYYY-MM-DD) when the file was last modified. Updated automatically by KB commands.
pinned No Boolean. When true, this file is always loaded at the start of every conversation. Default: false. Use sparingly.
scope No Glob pattern(s) matching file paths where this knowledge applies. Can be a single string ("src/api/**") or an array of strings (["src/api/**", "*.controller.ts"]). These patterns are surfaced in the CLAUDE.md table's "When to Load" column for efficient context matching.

File Format

Each KB file should follow this structure:

---
tags: [topic-tag]
related: [[other-kb-file]]
created: YYYY-MM-DD
last-updated: YYYY-MM-DD
pinned: false
scope: []                            # String or array of glob patterns for auto-matching
---

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

kb-init is a skill published in the GitHub repository charlesjones-dev/claude-code-plugins-dev (35 stars, last pushed 6d ago), licensed MIT. It adds 32 tokens to every session and 2,903 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
