Under **What it may change**, a goal picks which kinds of change its runs may propose. Anything not picked stays read only. Every change runs as the person who created the goal. Goals are created by admins and organization owners, which covers every change here. If the creator later loses that role, the change fails and nothing changes. Before it changes a CostGraph record, the agent reads the record to get its current state. After the change, it reads the record again to confirm the change took effect. ## Budgets These changes need **Budgets** under **What it may change**. The agent reads your budgets, with spend so far, forecast, and status, before and after each change. See [Budgets](/costgraph/budgets). | Change | What it does | | - | - | | Create a budget | Adds a budget with alert thresholds. Its currency must match the currency the spend is billed in | | Update a budget | Replaces the budget's scope, amount, thresholds, and owners | | Delete a budget | The budget stops tracking spend and sending alerts | ## Reports A workflow can create, edit, and duplicate reports in any goal. Sharing, scheduling, and deleting a report need **Reports** under **What it may change**. The agent reads the report before and after each change. | Change | What it does | | - | - | | Create a report | Saves a new report owned by the goal's creator | | Update a report | Renames a report, or changes its time range | | Save a report document | Saves a new version of the report. If the report changed since the agent read it, nothing is saved | | Duplicate a report | Copies a report into a new private report owned by the goal's creator | | Set report visibility | Shares a report with everyone in the tenant, or makes it private again | | Schedule a report | Sends a report daily, weekly, or monthly as CSV or XLSX. Sending to shared destinations needs an admin or owner | | Send a scheduled report now | Sends one copy now to the schedule's recipients | | Stop a report schedule | Deletes the schedule so the report is no longer sent | | Delete a report | Archives the report. Its version history is kept | ## Split rules These changes need **Cost allocation** under **What it may change**. The agent reads your split rules and their targets before and after each change. | Change | What it does | | - | - | | Create a split rule | Splits the spend of one tag value across other values of the same key: evenly, by fixed percentages, or in proportion to each target's own spend | | Update a split rule | Replaces a split rule and all of its targets | | Delete a split rule | The days it covered show unsplit again, or under the earlier rule | ## Tagging rules Applying tagging rules needs **Tagging rules** under **What it may change**. It makes the rules of a queued [virtual tag](/costgraph/virtual-tags/overview) suggestion live, which changes how your spend is attributed. CostGraph applies exactly the rules you approved, and changes nothing if the suggestion changed since. The agent reads your virtual tags and their rules to confirm. ## Prices These changes need **Pricing** under **What it may change**, and an admin or owner as the goal's creator. See [On-prem pricing](/costgraph/operator/on-prem-pricing). | Change | What it does | What it reads | | - | - | - | | Change virtual machine tags | Sets or removes allowlisted tags on a virtual machine. Setting `costgraph.ai/pricing-id.compute` assigns one of your compute prices; removing it returns the machine to automatic pricing | The virtual machine, its price, and its disks | | Set a disk price | Assigns one of your disk prices to a disk, or returns it to automatic pricing | The disk's price and where its pin comes from | ## Billing exports These changes need **Billing export** under **What it may change**, and an admin, owner, or billing admin as the goal's creator. The agent reads your billing export connections and their meters before and after each change. See [Billing exports](/costgraph/integrations/exports/overview). | Change | What it does | | - | - | | Create a meter | Binds a virtual tag key to a meter in a connected billing platform, so each value of the key is billed as a customer there | | Deactivate a meter | Stops the meter pushing usage. Everything it already reported is kept | | Reactivate a meter | Resumes a deactivated meter from what it already reported | | Run a billing export | Pushes settled usage for every active meter now, instead of waiting for the nightly run | ## Tickets Filing a ticket needs **Tickets** under **What it may change**, and a connected Jira, Linear, or GitHub. A workflow creates a ticket for an anomaly or a recommendation, in a project or repository your connection allows. Each anomaly or recommendation gets at most one ticket in each tool. CostGraph records the ticket's key and link on the run. See [Jira](/costgraph/integrations/jira), [Linear](/costgraph/integrations/linear), and [GitHub issues](/costgraph/integrations/github-issues). ## Cloud changes A workflow changes AWS resources through a connected AWS account with **Let Workflows make approved changes** turned on. The change must fall in a category the goal picked: **Compute**, **Databases**, **Snapshots**, or **Storage**. The agent inspects resources with read-only AWS calls before it proposes a change, and again afterwards to confirm it. The following AWS changes are available: * **EC2**: start or stop instances, change an instance's type, change an EBS volume's size, type, IOPS, or throughput, and add or remove tags. * **Auto Scaling**: change a group's minimum, maximum, or target size. * **EKS**: change a managed node group's scaling. * **RDS**: change an instance's class or storage, and start or stop instances and clusters. Cleanup needs **Also allow cleanup** on the AWS connection too. It lets a workflow delete unused EBS volumes, EBS snapshots, and RDS snapshots, release unused Elastic IPs, and set S3 bucket lifecycle rules. ## Pull requests A workflow can open a pull request in a repository the CostGraph GitHub App can reach. For example, it can lower a CPU request in a Helm values file. The change must fall in a category the goal picked: **Compute**, **Databases**, **GPUs**, **Snapshots**, or **Storage**. You approve the pull request's title, repository, and instructions. After approval, a separate repository agent makes the change on a new branch and opens the pull request into the approved base branch. CostGraph checks every GitHub write against your approval, and never writes to the default branch or to `.github/workflows` files. CostGraph then checks the pull request on GitHub and records it on the run. Nothing merges on its own. Review and merge the pull request in GitHub, or close it to discard the change. ## Next steps Review, approve, or reject a change. Start a workflow from chat, Slack, or MCP.
