@MatBenfield,

When the workflow is triggered by the events related to issue (issues or issue_comment), from the github context of the workflow run you can get the details of the issue via the object “github.event.issue”.
For example:

• github.event.issue.title - - the title of the issue.
• github.event.issue.body - - the body (or description) of the issue, it is the first comment when creating the issue.

A simple workflow example:

on: issues
jobs:

job1:

runs-on: ubuntu-latest

steps:

- name: View issue information

run: |

echo "Issue title: ${{ github.event.issue.title }}"

echo "Issue body: ${{ github.event.issue.body }}"
You also can print the whole github context to the logs to view more details.
  - name: View the github context
    run: echo "$GITHUB_CONTEXT"
    env:
      GITHUB_CONTEXT: ${{ toJson(github) }}
