kb-init

A repository setup command for creating a knowledge bank: organized Markdown files that store project decisions, context, lessons, and session notes.

In plain words
What is it for?
Run it once to create the knowledge-bank folders and indexes, and to connect the bank to CLAUDE.md.
Why use it?
It gives the project a consistent place to keep information that would otherwise be scattered or forgotten.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Per session 24 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 186 The whole file, excluding the scripts and references it only reads on demand.

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 2d 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.

What it actually says

KB Init

Initialize the knowledge bank for this repository.

FIRST: Load the knowledge-bank:knowledge-bank skill using the Skill tool, then execute Step 2a (INIT) from the skill.

This command:

  • Creates .knowledge-bank/ with category subdirectories (adr/, learnings/, decisions/, context/, sessions/)
  • Creates master INDEX.md and per-category INDEX.md files
  • Updates CLAUDE.md to reference the knowledge bank (or shows the snippet to add manually)

Run this once per repo before using any other kb-* commands.

Changes

What this file has done since we first saw it

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.
