Can I see the total amount of outstanding CORs for a project?

Yes! Use the `list_change_order_requests` tool. The agent will return all CORs, and you can ask it to calculate or filter for the total value of those in 'Pending' or 'Under Review' status.

How do I check the latest T&M tags from the field through the agent?

Use the `list_tm_tags` tool. Your agent will fetch the most recent digital Time & Material tags, allowing you to review labor hours and material usage without opening the web app.

Where do I find my Clearstory API Key?

Log in to Clearstory, navigate to **Settings > Offices**, select your office, and go to the **Integrations** tab. You can generate and copy your API key from there.
