description	Use when the user wants to create or modify IBM App Connect Enterprise Toolkit .msgflow files using validated node types and ACE Toolkit conventions.

ACE Message Flow Skill

Purpose

Use this skill when the user asks to create or modify ACE Toolkit .msgflow files that do not require connector-specific policy guidance.

When not to use this skill

• If the request includes connector-specific nodes, use skills/ace-connector-flows/SKILL.md.
• If the request is primarily about project scaffolding, use skills/ace-project-setup/SKILL.md.

Required reading order

1. skills/shared/skill-composition.md
2. skills/shared/ace-versions.md
3. skills/shared/message-flow-rules.md
4. skills/shared/node-types.md
5. skills/shared/review-checklist.md

Critical rules

• Create ACE Toolkit .msgflow files, not ACE Designer YAML.
• Do not invent xmi:type values or namespace prefixes.
• Validate node types using the ACE version guidance and shared node type reference.
• Ask for missing required node values when there is no obvious safe default.
• Do not use this skill alone when the request also requires Compute node implementation.
• If the request includes Compute node ESQL creation or modification, also use skills/ace-esql/SKILL.md and apply its guidance for the .esql artifact.

Output requirements

• Create or update the requested message flow artifacts.
• Provide a concise summary of what was created or changed.
• State any important assumptions that were required.
