Phase 1: Consistency Check

No consistency issues found this run:

  • All ./workflows/ files have matching ./docs/ pages ✅
  • All docs pages have corresponding README entries ✅
  • Docs style is consistent across pages ✅

Phase 2: New Workflow Proposal

Archie — On-Demand Mermaid Diagram Generator

Source: github/gh-aw/.github/workflows/archie.md

Why it's valuable: Complex issues and pull requests often describe flows, architectures, and component relationships in dense prose. Archie makes these instantly visual by generating 1–3 GitHub-compatible Mermaid diagrams on demand. A developer working through a complicated feature spec or a reviewer trying to understand a multi-step PR can comment /archie and get a clear diagram in seconds — without leaving the issue thread or opening a diagramming tool. The workflow is useful for any repository and any team size.

Merge rate: Archie is a newer addition to gh-aw's collection and is referenced in the design patterns blog as a "deep research agent" in the interactive ChatOps category. Similar interactive slash command workflows in the factory have achieved strong merge rates: Q at 78%, Grumpy Reviewer and others performing well as on-demand tools.

Generalization plan:

  • ✅ Removed shared/mcp/serena-go.md import (Serena was used for diagram generation consistency, but the AI model can generate valid Mermaid syntax directly)
  • ✅ Removed Phase 0 Setup section (Serena workspace configuration)
  • ✅ Removed all Serena MCP references from the agent prompt
  • ✅ Removed edit: and bash: true tools (only needed for Serena workspace setup)
  • ✅ Removed footer-workflow-recompile and footer-workflow-recompile-comment messages (gh-aw specific workflow sync notifications)
  • ✅ Kept all core diagram generation logic, diagram type guidance, and validation checklist
  • ✅ Kept the slash command trigger, add-comment safe output, and reaction: eyes trigger

Proposed name: archie

Files Changed

  • workflows/archie.md — New workflow file
  • docs/archie.md — New docs page
  • README.md — Added entry to Command-Triggered Agentic Workflows section

Adds the Archie workflow, which generates Mermaid diagrams for issues
and pull requests on-demand via the /archie slash command. The workflow
analyzes issue/PR content to visualize relationships, flows, and
structures as clear GitHub-compatible Mermaid diagrams.

- workflows/archie.md: Adapted from gh-aw archie.md, removing the
  Serena MCP dependency while retaining all core diagram generation logic
- docs/archie.md: Documentation page following existing docs style
- README.md: Entry added under Command-Triggered Agentic Workflows
