close-issues

name	close-issues
description	Close GitHub issues that have been implemented, with verification
argument-hint	<plan.md or issue numbers: 123,456>

Close GitHub issues after verifying their implementation is complete. Accepts either a plan file path (to extract referenced issues) or a comma-separated list of issue numbers.

Usage:

• /close-issues 5,6 — verify and close specific issues
• /close-issues plans/my-plan.md — find and close issues referenced in a plan

Argument Handling

Parse $ARGUMENTS to determine input mode:

• Comma-separated numbers (e.g., 5,6): treat as explicit issue list
• File path (e.g., plans/foo.md): read the file and extract issue numbers from #NNN references
• Empty: ask the user which issues to close

Steps

1. Gather issue list

If a plan file was provided:

• Read the plan file
• Extract all #NNN issue references (regex: #(\d+))
• Deduplicate and present the list to the user for confirmation before proceeding

If explicit issue numbers were provided, use them directly.

2. Fetch issue details

For each issue:

gh issue view <number> --json title,body,state,labels

Skip any issues that are already closed — report them as "already closed" in the final summary.

3. Verify implementation

For each open issue, verify the fix exists in the codebase:

1. Read the issue title and body to understand what was requested
2. Search for relevant commits: git log --oneline --all --grep="#<number>"
3. If no commit references the issue, search by keywords: git log --oneline -20 --grep="<keyword>"
4. Use Grep/Glob to spot-check that the described change actually exists in the codebase

Categorize each issue as:

• VERIFIED — implementation found
• PARTIAL — some work done but gaps remain
• NOT FOUND — no evidence of implementation

4. Close verified issues

For each VERIFIED issue:

gh issue close <number> --reason completed --comment "Closed — implemented in $(git log --oneline --all --grep='#<number>' | head -1 | cut -d' ' -f1). Verified in codebase."

5. Handle unverified issues

For PARTIAL issues:

• Do not close
• Add a comment noting what was implemented and what remains

For NOT FOUND issues:

• Do not close
• Report to the user

6. Report

Present a summary table:

| Issue | Title | Status | Action |
|-------|-------|--------|--------|
| #5    | ...   | VERIFIED | Closed |
| #6    | ...   | PARTIAL  | Commented |
