datafactory-tips

datafactory-tips is a skill for Claude Code, Codex from microsoft/DataFactory.MCP. It costs 49 tokens per session (968 once invoked), scanned A, original, MIT.

Operational guidance for Microsoft Fabric Data Factory, a service for building data-processing workflows, including query execution, dataflows, connections, and troubleshooting.

In plain words
What is it for?
Creating and refreshing dataflows, testing connections, iterating on M queries, filtering large datasets, and diagnosing timeouts.
Why use it?
It highlights tool limitations and ordering rules that can otherwise cause lost connections, slow queries, or failed dataflow changes.

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.

Security

Grade A, and why

datafactory-tips 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 5d 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.

Data Factory Tips

Operational knowledge for working with Microsoft Fabric Data Factory.

Must / Prefer / Avoid

MUST DO

  • Use executeOption = "ApplyChangesIfNeeded" on first refresh of API-created dataflows
  • Re-add connections via add_connection_to_dataflow after save_dataflow_definition (save may wipe them)
  • Use list_workspaces and filter by name — there is no find_workspace tool
  • Validate each connection with execute_query after adding
  • Create a new dataflow instead of reverting a multi-source one to single-source — there is no remove_connection tool

PREFER

  • Filter early in M queries to enable query folding (push filters to source)
  • Expensive operations (sorting, aggregation) last — streaming operations (filter, select) first
  • execute_query with customMashupDocument to iterate on M code before saving
  • Standard engine for complex transforms; Fast Copy only for simple ingestion

AVOID

  • get_authoring_guidance — deprecated, author M directly
  • Sorting early in query chains (requires reading all data before returning results)
  • SELECT * equivalent without row limits during development — use "Keep First Rows" then remove

Symptom Triage

Symptom Likely Cause Read
DataflowNeverPublishedError Default SkipApplyChanges on first run destinations/dest-new-table.md
DestinationColumnNotFound Manual mappings for new table destinations/dest-new-table.md
Credentials error on Lakehouse Connection not bound datafactory-connections.md (Binding)
FastCopy fails with transforms Unsupported transform in fast copy datafactory-advanced.md (Fast Copy)
Instant refresh fail (0-3s) Privacy firewall or unpublished draft sources/multi-source.md
Multi-source instant fail via API Dirty dataflow or separate Lakehouse.Contents calls sources/multi-source.md
IsNewTarget = false fails Direct navigation on API-created dataflow destinations/dest-new-table.md
Stale connections after revert save_dataflow_definition doesn't remove connections datafactory-connections.md (Troubleshooting)

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.
