kb

kb is a command for coding agents from TrafficGuard/typedai. It costs 0 tokens per session (186 once invoked), scanned A, original, MIT.

A command for extracting useful project knowledge from the current conversation and saving it as a dated Markdown file. Markdown is a plain-text format commonly used for documentation.

In plain words
What is it for?
Use it to record application features, file locations, design decisions, fixes, and project conventions in a knowledge-base file under the project’s kb directory.
Why use it?
It prevents important decisions, project structure, and lessons from being lost when the conversation ends. The saved report can help future developers or agents.

Command

Part of the knowledge plugin — 2 commands, 1 hook shipped together

Install

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.

agentmods
npx agentmods add commands/trafficguard/typedai/kb
Clone the repo
git clone --depth 1 https://github.com/TrafficGuard/typedai

Or install knowledge, the plugin that ships this one along with the rest of its 2 commands, 1 hook.

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 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 4d 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

Extract knowledge from the current conversation session to build the project knowledge base.

Carefully ultrathink reviewing in detail every message from the start of the conversation, taking notes on what was learnt along the way, such as:

  • Application design/features
  • File system paths and project structure
  • Why certain decisions were made
  • Fixed incorrect code/decisions
  • Project-level conventions, patterns, and designs

Focus on knowledge that can be provided to other developers and AI agents, both specific to the applications and general principles. Do NOT include details that are only specific to a single file - this is about capturing project-level knowledge.

After reviewing, save the knowledge report to a timestamped file:

mkdir -p kb && echo "Saving to kb/$(date '+%Y-%m-%d--%H-%M').md"

Write the knowledge report to that file, then confirm what was saved.

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.
