name	remove-contribfest-label
description	Use when the ContribFest event is over and you need to clean up GitHub issue labels — removes the "contribfest" label from every issue in public/issues.csv and adds "good first issue" to all Beginner-level issues in both the backstage/backstage and backstage/community-plugins repos.

Remove ContribFest Label

Overview

Reads public/issues.csv, then uses the GitHub REST API via curl to:

1. Remove the contribfest label from every issue listed
2. Add the good first issue label to every issue with level = Beginner

Assumes gh is already authenticated. Errors (e.g. label not present — returns 404) are skipped silently.

Important: Use curl with the REST API, not gh issue edit. The gh CLI uses Go's TLS stack which fails with certificate verification errors when called inside a bash loop on this machine.

CSV Format

repo,level,issueId
backstage/backstage,Beginner,33375
backstage/community-plugins,Intermediate,1234

The CSV uses Windows-style CRLF line endings — always pipe through tr -d '\r' before processing.

Repos present: backstage/backstage and backstage/community-plugins.

Step 1: Parse the CSV

From the repo root, print a quick summary so the user can confirm before making changes:

echo "Issues to process: $(tail -n +2 public/issues.csv | wc -l | tr -d ' ')"
echo "Beginner issues (will get 'good first issue'): $(grep -i ',Beginner,' public/issues.csv | wc -l | tr -d ' ')"

Tell the user what is about to happen and ask for confirmation before proceeding.

Step 2: Process Each Issue

Loop through every non-header row and apply the label changes. Use curl with the GitHub REST API, reading the CSV via a named file descriptor (fd3) so curl's stdin is unaffected.

REST API endpoints:

• Remove label: DELETE /repos/{owner}/{repo}/issues/{issue_number}/labels/{name}
• Add labels: POST /repos/{owner}/{repo}/issues/{issue_number}/labels with body {"labels":["good first issue"]}

A 404 on the DELETE means the label wasn't present — that's expected and safe.

Full loop (run from repo root)

GH_TOKEN=$(gh auth token)
tail -n +2 public/issues.csv | tr -d '\r' > /tmp/issues_clean.csv
while IFS=, read -r repo level issueId <&3; do
  owner="${repo%%/*}"
  reponame="${repo##*/}"
  echo "Processing $repo#$issueId (level: $level)..."
  curl -s -o /dev/null -w "%{http_code}" -X DELETE \
    -H "Authorization: Bearer $GH_TOKEN" \
    -H "Accept: application/vnd.github+json" \
    "https://api.github.com/repos/$owner/$reponame/issues/$issueId/labels/contribfest"
  echo ""
  if [[ "$(echo "$level" | tr '[:upper:]' '[:lower:]')" == "beginner" ]]; then
    curl -s -o /dev/null -w "%{http_code}" -X POST \
      -H "Authorization: Bearer $GH_TOKEN" \
      -H "Accept: application/vnd.github+json" \
      -H "Content-Type: application/json" \
      -d '{"labels":["good first issue"]}' \
      "https://api.github.com/repos/$owner/$reponame/issues/$issueId/labels"
    echo ""
  fi
done 3< /tmp/issues_clean.csv

Step 3: Print Summary

After the loop completes, print:

=== ContribFest Label Cleanup Complete ===

"contribfest" label removal attempted on: <total> issues
"good first issue" label added to: <beginner_count> issues

Repos affected:
  - backstage/backstage
  - backstage/community-plugins

Compute the counts from the CSV before running the loop so they are available for the summary.
