# All Takumi Assessments Now Require Credit Limits

Credit limits are now required for all Takumi assessments, including both blackbox and whitebox assessments.

This ensures you can **control credit consumption in advance, regardless of assessment type or mode, preventing unexpected large-scale credit usage**.

## What Changed

All blackbox and whitebox assessments now require credit limits for each phase (feature enumeration and scanning).

This prevents running large-scale assessments without credit limits and incurring unintended excessive credit consumption. If the actual consumption exceeds the specified credit limit, the excess credits will not be charged.

## Incremental Assessment Approach

With credit limits, all assessments support an incremental approach:

- **Start with a small credit limit** to understand the assessment's scope and the types of vulnerabilities detected
- **Review the interim report** to decide whether additional scanning is needed
- **Adjust credit limits and priorities as needed** to run additional scans

This allows you to progressively expand the assessment scope while reviewing results, without consuming a large amount of credits at once.

## Impact on Existing Assessments

In-progress and completed assessments are not affected. This change applies to newly created assessments going forward.
