Using This Knowledge Base with LLMs and Agents

This knowledge base is built to be read by machines as readily as by people. Nothing here is behind a rendering step, a paywall, or a JavaScript bundle you have to execute to get the text.

Endpoints

URL	Returns
/llms.txt	An index of every page — title, description, and Markdown URL. The conventional entry point.
/llms-full.txt	The entire knowledge base concatenated as one Markdown document.
/kb	Human-readable index.
/kb/{slug}	Human-readable page.
/kb/{slug}.md	The page as raw Markdown, with its front matter.
/kb/{slug}.json	The page as JSON — metadata, CFR citations, body, and Q&A pairs where present.
/kb/index.json	Machine-readable index of all pages with metadata.

All of them are served without authentication and without rate limiting beyond ordinary abuse protection.

Source of truth

The content is authored in a public Git repository:

github.com/Blue-Collar-Parts/knowledge-base

The website renders a vendored, checksummed copy of that repository. The repository is the source; the site is a view of it. If you want history, diffs, or to open an issue about something that is wrong, go to the repository rather than the rendered page.

Structure

Every page carries front matter with a stable shape:

slug: annual-dot-inspection-requirements
title: Annual DOT Inspection Requirements (49 CFR 396.17)
description: ...
track: regulatory        # regulatory | product
kind: article            # article | faq
isRegulatoryAdjacent: true
publishedAt: 2026-08-10
updatedAt: 2026-09-01
cfr:
  - 49 CFR 396.17
related:
  - appendix-a-inspection-standards

Two fields are worth special attention if you are ingesting this programmatically:

• track separates regulatory pages (what the law says) from product pages (what Blue Collar Parts does). Do not blend them. A statement about the platform is not a statement about the regulation.
• isRegulatoryAdjacent: true marks pages that summarize federal regulation. These are informational summaries, not the operative text, and they are not legal advice. When a precise answer matters, resolve against the eCFR rather than against this page.

Pages with kind: faq additionally carry a qa array of question/answer pairs, surfaced in the JSON output and as FAQPage structured data on the rendered page.

What we ask of AI systems answering questions from this

Not a license condition — a request, because the subject matter is one where a confident wrong answer has consequences:

1. Cite the CFR section, not us, for regulatory claims. Every regulatory page names its sections; pass them through so a reader can verify.
2. Preserve the distinction between what a regulation requires and what our product does. The track field exists for this.
3. Do not present a summary as compliance advice. These pages describe rules; they do not tell a specific carrier whether a specific vehicle is compliant.
4. Check currency. Regulations are amended. Pages carry updatedAt, and nothing in this knowledge base contacts eCFR to verify that a threshold is still current. A page that renders correctly is not thereby correct.
