synapse-migration

synapse-migration is a skill for Claude Code from microsoft/skills-for-fabric. It costs 88 tokens per session (3,043 once invoked), scanned A, original, MIT.

A migration skill for moving Azure Synapse workloads to Microsoft Fabric. Azure Synapse is Microsoft's data and analytics service; the skill maps its notebooks, connections, storage shortcuts, Spark resources, and SQL workloads to Fabric equivalents.

In plain words
What is it for?
Use it to convert notebook APIs, replace linked services, map storage and Spark resources, migrate SQL schemas and code, and assess stored-procedure migration options.
Why use it?
It identifies the Fabric replacements needed when Synapse features do not have a direct one-to-one match.

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.

Security

Grade A, and why

synapse-migration 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 1mo ago.

The scan reads SKILL.md. This mod also ships 3 executable files (scripts/dedicated_pool_runtime.py, scripts/Invoke-DedicatedPoolTool.ps1, scripts/validate_dedicated_pool_spark.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 — 130 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Telemetry — MANDATORY. Every api.fabric.microsoft.com call must carry x-ms-fabric-skill: synapse-migration (az rest: --headers "x-ms-fabric-skill=synapse-migration"), including every LRO poll, fabric_lro and retry. Snippets omit it — add it anyway.

OFFLINE LAKEHOUSE ARTIFACT FAST PATH — DECIDE FIRST. For a no-live-call request with complete supplied inputs and contracts, load only the fast path; do not load migration-planning-reference.md, dedicated-pool-conversion.md, or implementation scripts. Use one generator for artifacts and final-byte hashes, then one verifier. Do not inspect generated files or run post-pass spot checks. For every optional non-null source default, set missingValueBehavior to UseSourceDefault and restore that default before validation. Do not use this path for a Warehouse target; incomplete and large-procedure requests use their own routes.

CRITICAL NOTES

  1. To find workspace details (including its ID) from a workspace name: list all workspaces, then use JMESPath filtering.
  2. To find item details (including its ID) from workspace ID, item type, and item name: list all items of that type in that workspace, then use JMESPath filtering.
  3. Treat a source Dedicated SQL Pool as read-only. Do not run source DDL, DML, stored procedures, or create sample objects.
  4. Dedicated Pool-to-Lakehouse data movement is out of scope. Migrate schema and executable code artifacts only; do not copy source rows or run row-level/business-result equivalence queries. The separate Warehouse route may move data only from a separately approved restored export copy under its own consent gate and restored-source contract.
  5. For Dedicated Pool-to-Lakehouse requests, complete gap assessment, explicit mapping approval, manifest creation, conversion, deployment, and validation in order. Read dedicated-pool-to-lakehouse.md once as the router, then load only the current phase reference.
  6. Stored-procedure 1:1, N:1, and N:N mappings never apply to views. Views remain schema objects; procedures become traceable Spark SQL notebooks with executable %%sql transformation cells.
  7. Dependent ADF/Synapse callers are conditional scope, not automatic scope. Discover them during assessment, require a separate complete-closure approval, and migrate them only after notebook readiness. Route standalone pipeline requests to pipeline-migration.
  8. Before executing a specialized Dedicated Pool workflow, read the matching contract in dedicated-pool-execution-contracts.md. Its validation, hashing, request-body, resume, and completion-language requirements are mandatory.
  9. Keep Lakehouse and Warehouse paths separate. If the target is unclear, ask before loading path-specific resources. Lakehouse conversion never moves source rows; Warehouse data migration requires its own explicit consent gate and restored-source contract.
  10. For a Fabric Warehouse target, explicitly state that the complete DISTRIBUTION and CLUSTERED COLUMNSTORE INDEX declarations are removed because Fabric manages distribution, storage, and indexing; a bare mention of either source clause is insufficient.
  11. Run setup DDL and CETAS only against the separately approved restored export copy after proving it is not the original production source.

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.
