Guides a contributor from a workflow idea to a complete Workflow Implementation Packet (draft workflow file, draft workflow command, cross-cutting update checklist) in a staging area for review. Runs overlap analysis against the existing workflows with a Why Gate, then helps select and sequence skills with authored handoffs.

Prompt
When promoting a new workflow, multiple documentation and configuration surfaces need updates. Which specific file in `.github/workflows/` must be listed on the cross-cutting checklist despite being validator-blind?
What was checked, without and with the skill

PM Workflow Builder
This skill creates new multi-skill workflows for the pm-skills library. It
produces a Workflow Implementation Packet - a draft _workflows/<name>.md
file, a draft commands/workflow-<name>.md command, and the cross-cutting
update checklist - in a staging area for review before promotion to
canonical locations. The builder authors; it never executes a chain and it
never promotes its own output.
When to Use
You have an idea for a new multi-skill workflow ("I need a workflow for
quarterly business reviews")
You know the skills you want to chain and want them captured durably
("chain competitive-analysis, experiment-results, pivot-decision")
A /chain run (orchestrator Mode B) proved reusable and its completion
output suggested promoting the chain to a durable workflow; hand this
skill the exact chain expression from that suggestion
When NOT to Use
To run a sequence once without authoring anything -> use the /chain
command or utility-pm-workflow-orchestrator directly
To build or modify a single skill -> use utility-pm-skill-builder,
utility-pm-skill-validate, or utility-pm-skill-iterate
To customize an existing workflow -> edit its _workflows/<name>.md
directly; the overlap analysis below will point you there when coverage
is high
Instructions
Step 1: Understand the Idea
Accept the idea in any of three entry forms, all converging on the same
downstream flow:
Problem-first: "I need a workflow for X." Identify the recurring PM
process, who runs it, and the artifact trail it should leave.
Skills-first: a list of skills the user already wants to chain.
