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.

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 | $0.03046 | $0.03046 |
| Opus 5 | $0.01523 | $0.01523 |
| Sonnet 5 | $0.00609 | $0.00609 |
| Haiku 4.5 | $0.00305 | $0.00305 |
Grade A, and why
skills-for-fabric 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 — 189 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Microsoft Fabric Development Instructions
Updates:
fabric-collectionis a third-party marketplace, so enable auto-update once: run/plugin, open Marketplaces, selectfabric-collection, and choose Enable auto-update. Administrators can instead set"autoUpdate": trueon itsextraKnownMarketplacesentry in managed settings. To update on demand, runclaude plugin update <plugin>@fabric-collection. If these files were copied in loosely rather than installed as a plugin, compare the localpackage.jsonversion against the remote (git fetch origin main --quiet && git show origin/main:package.json) and re-copy if it is newer.
This project uses Microsoft Fabric for data engineering, warehousing, and analytics.
Architecture Mode
- Use the hybrid layering model: Agents → Skills → Common.
- For cross-workload orchestration, start with
agents/FabricDataEngineer.agent.md. - Delegate deep endpoint implementation to relevant skills under
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
Fabric REST APIs
All Fabric operations use the REST APIs documented at: https://learn.microsoft.com/en-us/rest/api/fabric/articles/
Developer vs Consumer Patterns
Developers
- Use REST APIs to create/manage artifacts (workspaces, warehouses, lakehouses)
- Use protocol-specific connections to access data:
- ODBC/JDBC for Warehouse queries
- Spark/PySpark for Lakehouse data
- XMLA/DAX for Semantic Models
- KQL for Real-Time Intelligence
Consumers
- Use MCP servers for natural language queries
- Limited to: Semantic Models, Warehouses, Lakehouse SQL Endpoints
- No ODBC/JDBC setup needed - MCP handles connections
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.

skills-for-fabric CLAUDE.md is an instructions file published in the GitHub repository microsoft/skills-for-fabric (1,122 stars, last pushed 2d ago), licensed MIT. It adds 3,046 tokens to every session, about $0.0152 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.
