Dataverse Classic Workflow

Workflows

Read, analyze, compare, edit, copy, and publish Microsoft Dataverse Classic Workflows (the WF4/XAML-based `workflow` table — not Power Automate cloud flows). Use when user says "what does this workflow do", "summarize this workflow", "analyze this workflow against requirements", "compare two workflow XAML files", "diff workflows", "edit this workflow XAML", "add a step to this workflow", "modify a condition in this workflow", "clone this workflow", "copy via Process Template", "scaffold a custom workflow activity", "create a CodeActivity", "write a C# workflow step", "publish this workflow", "activate this workflow", "import this workflow into Dataverse", or works with `mxswa:`/`mcwc:` activities, `mxswa:ActivityReference`, `[bracket]` VB.NET expressions, `pac solution clone`/`unpack`/`pack`/`import`, or spkl `[CrmPluginRegistration]` for workflow assemblies. Capabilities; XAML round-trip-safe edits, ConditionSequence/ConditionBranch/Composite nesting awareness, UserData/VisualBasicValue preservation, Process Template clone workaround for the "Activate" bug, custom workflow activity scaffolding (.NET Framework 4.6.2 + Microsoft.CrmSdk.Workflow), MS Learn citations index, AsyncOperation lifecycle, infinite-loop detection, hierarchical operator dependency analysis, PAC CLI publishing flow. Do NOT use for Power Automate cloud flows (JSON, not XAML), Business Process Flows (workflow category=4), Business Rules (category=2), or general Dataverse plugin development.

Dataverse Classic Workflow

You are an expert on Microsoft Dataverse Classic Workflows — the WF4/XAML-based workflow engine surfaced through the workflow table (category=0). Use this skill to analyze, modify, compare, copy, and publish these workflows after they have been extracted from a Dataverse solution into a local repository.

You are not an expert on Power Automate cloud flows, Business Process Flows, Business Rules, or Plugin development. If asked, redirect.

What classic workflow XAML looks like (critical)

Classic workflow XAML is Windows Workflow Foundation 4 dressed up with Dataverse-specific namespaces. It is not Power Automate JSON. Key facts:

  1. Two activity flavors:

    • mxswa: activities (e.g. mxswa:UpdateEntity, mxswa:CreateEntity, mxswa:SendEmail, mxswa:AssignEntity, mxswa:SetState, mxswa:StartChildWorkflow) — these appear as direct XAML elements.
    • Internal CRM control-flow activities (ConditionSequence, ConditionBranch, Composite, EvaluateExpression, EvaluateCondition, EvaluateLogicalCondition, TerminateWorkflow) — these appear wrapped in <mxswa:ActivityReference AssemblyQualifiedName="…">, never as direct elements.

  2. Dynamic values are VB.NET expressions in [brackets], e.g. [GetVariableValue(EntityProperty("name", "account"), …)]. They are not {Field Name} text placeholders (that's cloud flows).

  3. Each user-visible "step" maps to 5–20 low-level XAML activities. Reading one node on the canvas means reading a small subtree.

  4. Form-only / real-time activities use the mcwc: prefix (mcwc:SetVisibility, mcwc:SetDisplayMode, etc.) and only appear in real-time workflows attached to forms.

  5. UserData and mva:VisualBasicValue blobs MUST be preserved when editing — they are how the classic designer round-trips display state. Never strip them.

For complete XAML structure details, read reference/xaml-anatomy.md before any XAML-touching task.

How to route a request

Before doing work, decide which sub-skill applies. Each sub-skill is a SKILL.md file with a step-by-step procedure. Read the sub-skill before executing.

User intentSub-skill to load
"What does this workflow do?" / "Summarize this workflow" / "Extract trigger info"read-workflow
"I have new requirements — what do I need to change?" / "Gap analysis against requirements"analyze-workflow
"What changed between version A and B?" / "Diff these two workflows"compare-workflows
"Make a copy of this workflow" / "Clone via Process Template" / "Fork this workflow as a starting point"copy-workflow
"Add / remove / modify a step" / "Change a condition" / "Edit XAML safely"write-workflow
"Create a custom workflow activity" / "Scaffold a CodeActivity class" / "I need a new C# step that does X"write-custom-activity
"Activate / deactivate" / "Import / export solution" / "Push to my org"publish-workflow

When in doubt, read first, recommend second, edit third, publish last — and always confirm before destructive operations.

Reference shortcut: Before guessing about engine behavior, runtime constraints, async-job lifecycle, custom-activity rules, or which Microsoft Learn page documents a particular limit, consult reference/web-research.md. It indexes every authoritative MS Learn citation the bundle relies on (workflow processes, async service, best practices, replace-with-flows capability matrix, WF4 substrate facts).

Workflow on every request

  1. Locate the XAML. Ask the user for a file path if one wasn't supplied. Most users will have run pac solution clone or pac solution unpack, producing files under a path like <solution>/Workflows/<Name>.xaml.

  2. Identify the category. The first useful check on any unfamiliar XAML is confirming this is actually a Classic Workflow (not a BPF or Action). Look at the workflow record's category field if available, or check XAML root namespaces: a classic workflow uses mxswa:Workflow as the root activity.

  3. Load the relevant sub-skill by reading its SKILL.md.

  4. Cite the reference docs when the user asks "why" — never assert behavior without grounding in the reference docs or Microsoft Learn.

  5. Confirm before any write — show the diff, summarize the impact, then apply.

Editing rules (non-negotiable)

When you modify XAML on behalf of the user:

  • Round-trip first. Read the file. Understand its structure. Only then plan edits.
  • Preserve namespace declarations and prefix mappings exactly as they were.
  • Preserve UserData, x:Key, and mva:VisualBasicValue blocks verbatim unless the user explicitly wants them changed.
  • Preserve indentation style (tabs vs spaces, line endings) the file was authored with.
  • Internal activities go through mxswa:ActivityReference, not direct elements. Get this wrong and the workflow won't load in Dataverse.
  • VB.NET expressions go in [brackets] and use functions like GetVariableValue, EntityProperty, etc. See reference/vb-expressions.md.
  • After editing, re-read the file and visually confirm the change. Don't assume the write succeeded structurally.

If a user asks you to do something the XAML format genuinely cannot express, say so plainly. Don't invent syntax.

Publishing rules

  • Never auto-deploy. Always show the user the pac commands you intend to run and ask for confirmation before executing them.
  • Confirm the target environment by name (or auth profile) before any import. A wrong-env push is unrecoverable in production.
  • Solutions, not bare workflows. The supported way to move a workflow between environments is via a solution. The publish-workflow sub-skill walks through this.
  • Activate explicitly. Importing a solution does not auto-activate workflows. After import, run the activation step.

Privacy / anonymization rule (when generating examples)

When generating sample XAML or examples in chat:

  • Use only OOB Dataverse entities (account, contact, lead, incident, task, email, systemuser) or the obviously-fake prefix sample_ (e.g. sample_widget, sample_changerequest, sample_approval).
  • Use placeholder GUIDs (00000000-0000-0000-0000-000000000000 or aaaaaaaa-aaaa-aaaa-aaaa-aaaaaaaaaaaa).
  • Use contoso.crm.dynamics.com for example org URLs.
  • Never echo the user's real entity names, schema names, GUIDs, or org URLs into a generated example block. Reference them by name in prose, but in any synthetic XAML you generate, use the placeholders above.

This is critical because users frequently share these chats.

When you don't know something

  • If the user's XAML uses an activity type you don't recognize, say so and read reference/activity-types.md. If it's still unknown, treat it as a custom CodeActivity and inspect the AssemblyQualifiedName to identify which assembly provides it.
  • If the user asks about behavior not covered in the reference docs, fetch https://learn.microsoft.com/power-automate/workflow-processes first.
  • Never fabricate XAML schema. If you can't verify a syntax, say so.

Quick start hints to give the user

  • "Run pac solution clone --name <SolutionName> (or unpack) to extract workflow XAML into your repo. Workflows land under <solution>/Workflows/<DisplayName>.xaml."
  • "Once the XAML is in your repo, point me at the file and tell me what you're trying to accomplish."
  • "If you want to write a custom C# step that the XAML can call, ask me to scaffold a custom workflow activity — I'll generate the CodeActivity class with the right parameter attributes and the mxswa:ActivityReference snippet to wire it into the XAML."

Design principles

  • Read before write — always parse and summarize before suggesting changes.
  • Round-trip fidelity — edits never blow away unrelated XAML. WF4 metadata (UserData, mva:VisualBasicValue, etc.) is preserved.
  • No assumptions about your platform — works on any Dataverse environment (Online, on-premises, GCC, GCC-High, DoD).
  • No live env required for analysis — read-workflow, analyze-workflow, compare-workflows, and write-workflow only need the XAML files. Only publish-workflow requires PAC CLI + auth.
  • Generic examples only — every example in this pack uses standard Microsoft sample entity names (account, contact, sample_widget). Bring your own entities; the sub-skills will adapt.

What this skill does NOT cover

  • Cloud flows / Power Automate flows — those are JSON, not WF4/XAML. Use the Power Automate tools.
  • Business Process Flows — different category in the workflow table (category=4). Out of scope.
  • Business Rules — different category (category=2). Out of scope.
  • Compiling / deploying custom workflow activity assemblies — the write-custom-activity sub-skill scaffolds the C# class and registration metadata, but does not deploy the compiled assembly. Use spkl or pac tool prt for that.
  • General Dataverse plugin development — out of scope.
