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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.03925 | $0.03925 |
| Opus 5 | $0.01962 | $0.01962 |
| Sonnet 5 | $0.00785 | $0.00785 |
| Haiku 4.5 | $0.00392 | $0.00392 |
Grade A, and why
ab100 CLAUDE.md 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 5d 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.
How it starts
The opening of the file, as written. The whole thing — 182 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CLAUDE.md
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
Repository purpose
This repo has three complementary missions:
- Live training scaffolding -- companion material for Tim Warner's O'Reilly Live Learning course Agentic AI Business Solutions Architect (4 hours, delivered April 2026). The authoritative plan is
docs/course-plan-april-2026.md. - AB-100 Cert Buddy -- a GitHub Copilot agent that generates practice questions, hands-on labs, and personalized study plans for Microsoft exam AB-100: Agentic AI Business Solutions Architect. The agent, skills, prompts, and MCP server live under
.github/and.vscode/. - Hour 3 Deploy POC stack -- a working Foundry agent + MCP + ACA + APIM proof of concept under
src/. Five bash scripts spin up the gateway-fronted MCP server that wraps an existing Foundry agent; one script tears it down. Used as the live demo for Hour 3 (Deploy) and as the structural base for the Hour 4 (Security) bridge.
This is Tim Warner's instructor source of truth and learner reference material. There is one minimal Python app (the MCP server in src/app/) and one Bicep stack; no test suite. Build pipelines: the slide deck (see "Slide deck build" below) and the POC deploy scripts (see "POC stack" below).
Slide deck build
The course slide deck is generated from HTML source files via Node, not authored in PowerPoint:
- Source:
docs/deck-build/slides/*.html-- one HTML file per slide, ordered by filename. Slides use Tim's brand palette (#1F2A56navy,#00B4D8cyan,#F4845Forange) and a fixed720pt x 405pt16:9 layout. Existing CSS classes (.header,.tag,.box,.card,.foot) define the look -- match them when adding slides. - Build:
cd docs/deck-build && node build.js. Reads theslidesarray inbuild.js(slides are added to the deck in array order, NOT filename order) and writesdocs/ab100-course-deck.pptx. - Sync: after every rebuild, also copy
docs/ab100-course-deck.pptxoverdocs/ab100-course-deck-july-2026.pptx. The dated filename is the canonical artifact referenced from other docs; the undated one is just the build output. - Renderer constraint:
html2pptx.jsrequires every text node be wrapped in<p>,<h1>-<h6>,<ul>, or<ol>. Bare text inside<div>or<span>fails the build with a validation error. - New slides: when adding a slide between existing ones, name it with a letter suffix (e.g.
05a-seg1-saas-first.htmlbetween05and06) and add it to theslidesarray inbuild.jsat the correct position. Do not renumber existing files.
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.

ab100 CLAUDE.md is an instructions file published in the GitHub repository timothywarner-org/ab100 (37 stars, last pushed 1mo ago), licensed MIT. It adds 3,925 tokens to every session, about $0.0196 per session on Opus 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.
