GitHub Milestone Triage for ailujsoi

Overview

Assign milestone-unassigned open issues to the best-fit existing milestone, or propose a new milestone when an issue clearly belongs to a missing category. Prefer the most specific milestone and document the reason.

When to Use

• A user asks you to triage open issues without milestones.
• You are grooming the backlog and milestones exist but are under-used.
• You need to decide whether a new milestone category is justified.

Core Pattern

1. List unassigned open issues

   gh issue list --state open --milestone none --limit 200
   

2. List existing milestones with context

   gh api repos/AtelierArith/ailujsoi/milestones --paginate \
     --jq '.[] | "\(.title): \(.description // "no description") (open:\(.open_issues))"'
   

3. Classify each issue using the mapping below.
4. Propose a new milestone only if the issue has a coherent theme that does not fit any existing milestone and is likely to attract more issues.
5. Batch-assign by milestone

   gh issue edit NUM1 NUM2 NUM3 --milestone "Exact Milestone Title"
   

6. Verify nothing is left unassigned

   gh issue list --state open --milestone none --limit 200

Tie-Break Rules

Conflict	Prefer
Multiple milestones could fit	The most specific milestone (narrow scope beats broad scope).
Performance vs. feature work	The milestone that names the primary intent of the issue.
Documentation vs. UX text	Documentation if it changes reference/help content; Frontend/UX if it changes in-app strings.
Testing/CI/coverage improvements	Quality & Reliability or DevEx if it exists; otherwise Tech Debt only if it is maintenance.
Infrastructure vs. backend	Backend if it changes application logic; a new milestone only if it is observability/security/DevEx/quality & reliability.

New Milestone Checklist

Before creating a new milestone, confirm:

• The issue does not fit any existing milestone even with loose interpretation.
• The category has a clear, short title (2–5 words).
• You can describe it in one sentence.
• At least one other open or upcoming issue plausibly belongs there.

Good names: "Observability & Monitoring", "Quality & Reliability", "Developer Experience".

Common Mistakes

• Creating a milestone for one issue. A single issue should usually fit an existing bucket.
• Ignoring milestone descriptions. Read descriptions; titles can be misleading.
• Using broad catch-all milestones. Route to the actual subsystem or quality area.
• Not verifying. Always re-run the unassigned list after batch edits.
