Connect a Live Data Source to Your Workflow

Workflows become truly powerful when they act on real, up-to-the-minute data — not just canned prompts.

:dart: What You'll Do

You'll extend your daily-status workflow to fetch open issues from your repository using the GitHub CLI, then inject that data into your AI prompt. By the end, your summary will include an overview of outstanding issues alongside the commit activity.

:clipboard: Before You Start

• You have installed the gh-aw extension in Install the gh-aw CLI Extension.
• You have a working daily-status workflow from Build: Daily Repo Status Workflow.
• You're comfortable running and iterating on workflows from Refine, Test, and Improve Your Workflow.

Steps

Understand the data-flow pattern

gh-aw workflows run inside GitHub Actions, so your workflow can fetch live repository data before the AI writes anything. In this step, use shell steps to collect data and a later prompt section to turn that data into a summary.

Think of it as a handoff. First, the workflow gathers facts in a predictable way. Then, the prompt reads those saved results and asks the AI to explain what matters.

Fetch commit history

In your Copilot CLI session in the terminal, paste:

/agentic-workflows update .github/workflows/daily-status.md to add two shell steps
that fetch (1) the recent commit log from the last 24 hours with step id `recent`
and (2) all open issues with step id `issues`, and update the AI prompt to inject
those step outputs into the summary.

The skill adds both steps and updates the task brief. Review the diff before committing.

:pencil2: Manual edit path

Open .github/workflows/daily-status.md and add two steps to the steps: block in the frontmatter.

First, fetch the recent commit log, then fetch open issues (see the YAML reference blocks below). After adding both steps, run gh aw compile and push.

Here is what the first step looks like — the skill will add this for you:

First, fetch the recent commit log:

- name: Fetch recent commits
  id: recent          # step ID — referenced as steps.recent.outputs.…
  run: |
    # Lists commits from the last 24 hours (max 10), format: "<hash> <subject>"
    COMMIT_LOG=$(git log --oneline --since="24 hours ago" --format="%h %s" | head -10)
    # <<EOF writes a multi-line value to $GITHUB_OUTPUT
    echo "commit_log<<EOF" >> $GITHUB_OUTPUT
    echo "$COMMIT_LOG" >> $GITHUB_OUTPUT
    echo "EOF" >> $GITHUB_OUTPUT

:thinking: Pause and predict: What will the commit_log output contain if no commits were made in the last 24 hours? Form your prediction now and verify it after you trigger a run.

Fetch open issues

Next, add a step to fetch open issues:

- name: Fetch open issues
  id: issues          # step ID — referenced as steps.issues.outputs.…
  run: |
    # Fetch the 10 most recent open issues, formatted as "#42 Fix the bug"
    ISSUE_LIST=$(gh issue list --state open --limit 10 \
      --json number,title \
      --jq '.[] | "#\(.number) \(.title)"')
    # Count all open issues
    ISSUE_COUNT=$(gh issue list --state open --json number --jq 'length')
    echo "open_issues<<EOF" >> $GITHUB_OUTPUT
    echo "$ISSUE_LIST" >> $GITHUB_OUTPUT
    echo "EOF" >> $GITHUB_OUTPUT
    echo "open_issues_count=$ISSUE_COUNT" >> $GITHUB_OUTPUT
  env:
    GH_TOKEN: ${{ secrets.GITHUB_TOKEN }}  # provided automatically — no setup needed

:pencil2: Try it: Run gh issue list --state open --json number --jq 'length' in your terminal and note the count. After you trigger a workflow run, check whether the workflow reports the same total.

:thinking: Pause and predict: What will the AI receive if the issue list is empty? Will the prompt still produce a useful output?

Inject data into your AI prompt

The AI prompt lives in the Markdown body after the frontmatter. Update that section so it uses the step outputs:

---
# … your existing frontmatter with the two new steps …
---

Summarise recent activity in this repository.

Recent commits (last 24 hours):
${{ steps.recent.outputs.commit_log }}

Open issues (${{ steps.issues.outputs.open_issues_count }} total):
${{ steps.issues.outputs.open_issues }}

Write a concise, friendly update — two short paragraphs.
Highlight anything that looks urgent in the issue list.

GitHub resolves the step-output expressions before the AI sees the prompt, so the model receives plain text instead of workflow syntax.

:thinking: Pause and predict: If the commit_log output is empty, does the prompt still make sense to the AI? What one-line change would make the instruction more robust?

:pencil2: Try it: Change "two short paragraphs" to "one bullet list per topic" and re-run. Notice how the output format shifts.

Compile, push, and test

The /agentic-workflows skill recompiles the lock file automatically. If you edited the workflow manually, run gh aw compile first, then push:

git add .
git commit -m "feat: inject open issues into daily summary prompt"
git push

Open the Actions tab and verify the new steps appear and the AI summary mentions both commits and issues.

Try other data sources

Once you're comfortable with this pattern, the same technique works for:

Data	Command
Open pull requests	gh pr list --state open
Recent releases	gh release list --limit 5
Failed workflow runs	gh run list --status failure --limit 5
Repository stats	gh api repos/:owner/:repo

✅ Checkpoint

• Your workflow has a recent-commits step with id: recent
• Your workflow has an open-issues step with id: issues
• Your AI prompt uses both saved outputs
• Both .github/workflows/daily-status.md and .github/workflows/daily-status.lock.yml are compiled, committed, and pushed
• A manual run completes and the summary mentions both commits and open issues
• You can explain how the workflow passes fetched data into the prompt
• You can describe what happens if the recent commit output is empty and how your prompt handles it
