Add Mermaid diagram for safe output message flow #3428

Copilot · 2025-11-07T05:00:04Z

Adds visual representation of the safe output system flow from AI-generated content to GitHub API operations, addressing documentation enhancement request from #3416.

Changes

Added flowchart showing complete message flow:
- AI agent output → staged mode decision → safe output type routing → message pattern application → GitHub API execution → success summary
- Both staged (preview) and live execution paths
- All 6 safe output types: create-issue, create-discussion, add-comment, create-pull-request, create-pr-review-comment, update-issue
- All 4 message patterns: AI attribution footer, installation instructions, related items links, patch preview
Files modified:
- specs/safe-output-messages.md - Source specification
- .github/instructions/developer.instructions.md - Consolidated developer docs

Original prompt

This section details on the original issue you should resolve

<issue_title>[task] Add Mermaid diagram for safe output message flow</issue_title>
<issue_description>## Objective
Create a Mermaid diagram visualizing the safe output message flow to enhance understanding of the relationship between different message patterns.

Context

The documentation consolidation report (Discussion #3416) identified this as a potential future improvement. While the current documentation is clear without it, a visual representation would help developers understand the flow from AI output to GitHub API operations.

Approach

Review the Safe Output Messages section in specs/safe-output-messages.md

Design a Mermaid flowchart showing:

AI agent output generation

Safe output processing

Message pattern application

GitHub API operation execution

Add the diagram to the appropriate section in the consolidated file

Ensure diagram follows the same style as existing 9 diagrams

Files to Modify

specs/safe-output-messages.md - Add Mermaid diagram

.github/instructions/developer.instructions.md - Update consolidated file with new diagram

Acceptance Criteria

Mermaid diagram created showing safe output message flow

Diagram visualizes: AI output → Processing → Message patterns → GitHub API

Diagram style consistent with existing 9 diagrams

Diagram renders correctly in GitHub markdown

Added to both source spec and consolidated documentation

Documentation remains clear and not overly complex

Priority

Low - Enhancement rather than fix. Current documentation is already clear without this diagram.

The flow diagram shows that "Apply Message Patterns" (N) branches into four parallel operations (O, P, Q, R) that each independently flow to "Execute GitHub API Operation" (S). This implies four separate API executions, which is inaccurate.

In the actual implementation (e.g., pkg/workflow/js/create_issue.cjs), all message patterns (AI attribution footer, installation instructions, related items links, patch preview) are applied within a single JavaScript function that executes as part of one GitHub API operation.

Consider revising the diagram to show that O, P, Q, and R all converge into a single path before reaching S, or restructure it to show these as aspects/attributes of the message preparation rather than sequential steps. For example:

N --> O[Prepare Message Content] O --> |Add AI Attribution| O O --> |Add Installation Instructions| O O --> |Add Related Items Links| O O --> |Add Patch Preview| O O --> S[Execute GitHub API Operation]

Loading

Or simply show them as a grouped operation that happens before the API call.

🎉 PR Nitpick Review - Clean Code!

After carefully reviewing this PR, I'm pleased to report that no nitpicks were found. The code changes demonstrate excellent quality and consistency with the project's established patterns.

What Was Reviewed

Files Changed: 2 markdown documentation files
Lines Added: +88 lines (identical Mermaid diagram in both files)
Lines Removed: 0 lines
Type: Documentation enhancement

Positive Highlights ✅

1. Excellent Diagram Design

Clear hierarchy: Top-down flow from AI output through to step summary
Consistent node naming: Uses single-letter variables (A-U) following Mermaid conventions
Logical grouping: Message patterns (O, P, Q, R) converge before API execution
Appropriate decision nodes: Uses diamond shapes for "Staged Mode?" and "Safe Output Type" branching

2. Strong Documentation Structure

Contextual placement: Diagram appears immediately after the overview section, providing visual context before diving into message categories
Supporting text: Flow stages enumeration (1-6) reinforces the diagram's visual narrative
Dual maintenance: Diagram correctly added to both source spec (specs/safe-output-messages.md) and consolidated developer docs (.github/instructions/developer.instructions.md)

3. Consistency with Project Standards

Diagram count tracking: PR description notes "Diagram count: 9 → 10", showing awareness of documentation metrics
Naming conventions: Follows existing Mermaid diagram patterns used throughout the project
Formatting: Proper markdown fencing with mermaid language tag

4. Diagram Accuracy

All 6 safe output types represented: create-issue, create-discussion, add-comment, create-pull-request, create-pr-review-comment, update-issue
All 4 message patterns shown: AI attribution footer, installation instructions, related items links, patch preview
Staged mode flow: Correctly shows preview path vs. live execution path

Summary

This is a model documentation PR:

✅ Clear visual enhancement to existing documentation
✅ No code quality issues or inconsistencies
✅ Follows project conventions perfectly
✅ Dual-file maintenance done correctly
✅ Accurate representation of the system architecture

Great work! 🎯 This diagram will significantly help developers understand the safe output message flow at a glance.
