What is skills-for-fabric AGENTS.md?

Repository guidance for Microsoft Fabric, a cloud platform for data storage, processing, and analytics. It explains the project structure and how to sign in to Azure and obtain access tokens for Fabric services.

Planning Fabric data projects, choosing the right agent or skill, logging in to Azure, and calling Fabric or SQL APIs.

It prevents an agent from using the wrong architecture or authentication method when working with Fabric resources.

How microsoft/skills-for-fabric configures Codex and OpenCode

About the project

Microsoft Fabric Skills is a collection of reusable instructions and MCP systems that help AI assistants work with Microsoft Fabric workloads, APIs, queries, and operations. It is intended for users of GitHub Copilot CLI and compatible coding tools; the catalogue entries are the skills, agents, instructions, MCP systems, plugins, and rules distributed by the project.

Token cost

What it costs to keep this loaded

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	$0.02721	$0.02721
Opus 5.5	$0.01088	$0.01088
Sonnet 5.5	$0.00544	$0.00544
Haiku 4.5	$0.00272	$0.00272

Security

Grade A, and why

skills-for-fabric AGENTS.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 today.

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.

Microsoft Fabric Development Agent

Updates: These instructions do not run a session-start update check. Refresh them through your host's plugin or marketplace update flow, or run git pull if you use a manual clone.

You are an AI assistant specialized in Microsoft Fabric development.

Architecture Mode

This repository uses a hybrid model: Agents → Skills → Common.
For cross-workload orchestration (medallion architecture, migration, ETL across Spark + SQL + KQL), use agents/FabricDataEngineer.agent.md.
Delegate endpoint-specific implementation depth to skills in skills/.

Authentication

All Fabric operations require Azure AD authentication. For development:

# Login to Azure
az login

# Get token for Fabric REST API
az account get-access-token --resource https://api.fabric.microsoft.com

# Get token for SQL connections (Warehouse, Lakehouse SQL Endpoint)
az account get-access-token --resource https://database.windows.net

Local Codex needs its own MCP configuration to reuse Azure CLI sign-in. See mcp-setup/README.md; reading these instructions alone does not register MCPs.

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.
