# Preview a change before it runs

Request and review a side-effect-free Podigee preview before a consequential change.

Ask Podigee to normalize and validate a consequential change without applying it.

## Before you start

* Verify the connected Podigee account.
* Confirm that the connection has the required read and write scopes.
* Gather the exact target and requested values.
* Do not ask the agent to work around a failed preview with another tool.

## Request the preview

1. Ask the agent to prepare the intended change without applying it.
2. The agent calls the relevant tool with `dry_run: true`.
3. Review the action and target.
4. Review every normalized value.
5. Review warnings, permanent effects, and external effects.
6. Confirm that the selected account and podcast are correct.
7. Approve or reject the proposed plan.

A valid preview can return a request digest and a short confirmation value that starts with `cfm_`. The agent should preserve both without exposing the signed token contents.

## Expected result

Podigee returns a side-effect-free description of the accepted request. The target data does not change. The preview identifies the exact request that a later confirmation can authorize.

## If the preview fails

Use the returned code and message. Correct invalid or missing values, permissions, plan access, or resource state, then request a new preview.

Do not retry a plan-limit result as a temporary failure. Do not switch tools to avoid a required confirmation.

## Next step

[Confirm a consequential change](/documentation/start-here/ai-agents/make-changes-safely/confirm-a-consequential-change.md) after the preview matches the user's intent.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.podigee.com/documentation/start-here/ai-agents/make-changes-safely/preview-a-change-before-it-runs.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
