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 | $0.03128 | $0.03128 |
| Opus 5 | $0.01564 | $0.01564 |
| Sonnet 5 | $0.00626 | $0.00626 |
| Haiku 4.5 | $0.00313 | $0.00313 |
Grade A, and why
Agent365-nodejs 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 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.

Project Overview
The Microsoft Agent 365 SDK extends the Microsoft 365 Agents SDK with enterprise-grade capabilities for building sophisticated AI agents. This Node.js/TypeScript monorepo provides comprehensive tooling across four core areas:
- Observability: OpenTelemetry-based tracing and monitoring for agent applications
- Notifications: Agent notification services and lifecycle event handling
- Runtime: Core utilities for agent operations and Power Platform integration
- Tooling: MCP (Model Context Protocol) server configuration and tool discovery
Essential Commands

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.

Agent365-nodejs CLAUDE.md is an instructions file published in the GitHub repository microsoft/Agent365-nodejs (24 stars, last pushed 1mo ago), licensed MIT. It adds 3,128 tokens to every session, about $0.0156 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.
