microsoft/Agent365-nodejs is a Node.js and TypeScript SDK for building Microsoft 365 agents with observability, notifications, runtime utilities, and development tools. Developers use it for agents connected to platforms such as Microsoft 365, Teams, Copilot Studio, and Webchat, while the catalogue entries are agents and instructions for the SDK.

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 | $0.03128 | $0.03128 |
| Opus 5.5 | $0.01251 | $0.01251 |
| Sonnet 5.5 | $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 2mo 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

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 today), licensed MIT. It adds 3,128 tokens to every session, about $0.0125 per session on Opus 5.5. 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.
