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 | $0.02895 | $0.02895 |
| Opus 5 | $0.01448 | $0.01448 |
| Sonnet 5 | $0.00579 | $0.00579 |
| Haiku 4.5 | $0.00290 | $0.00290 |
Grade A, and why
Agents-for-python 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 yesterday.
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 — 365 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 Overview
This is the Microsoft 365 Agents SDK for Python, a framework for building enterprise-grade conversational agents for M365, Teams, Copilot Studio, and other platforms. The SDK replaces the legacy Bot Framework SDK (botbuilder packages) with a modern, modular architecture.
Important: Python imports use underscores (microsoft_agents), not dots (microsoft.agents).

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.

Agents-for-python CLAUDE.md is an instructions file published in the GitHub repository microsoft/Agents-for-python (210 stars, last pushed 4d ago), licensed MIT. It adds 2,895 tokens to every session, about $0.0145 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.
