Source references, missing information, and questions to review stay with the findings.
How to use it
Add the skill to your AI
Open your download and follow the start guide. Use an AI agent that can load skill files and run the included tools.
Provide your records
Old/new ledgers. Confirm the case and period you want to check.
Ask for the report
Copy the request below into your agent. Add the files and any task details it needs.
Review and save
Check the findings against the original records. Choose where to save the report and follow up on open questions.
Example request
Use the Billing Migration Historical Credit Trace skill. Review the attached records: old/new ledgers. Prepare this result: credits lost or duplicated during transfer. Include a source reference for each finding. List missing information and questions that need my review. Ask me to confirm the scope and where to save the report before you start.
What it checks
It adds the amounts for each item and compares the total with your starting figure. The report shows the difference and its source records.
What you provide
Old/new ledgers.
Details it records
- Old credit
- Migrated credit
- Documented adjustments
Read the full task logic
For this task, keep one review row for each customer + migration credit currency. Record old credit, migrated credit, and documented adjustments. Keep the source location beside each value.
Use effective dates for seats, usage, pauses, price overrides, and credits. Preserve invoice cutoff and late-arriving events.
Require the approved proration rule, day-count convention, and rounding tolerance. Keep contract commitments separate from cash payments.
The engine cannot establish that all transactions were exported. It does not perform currency conversion, infer missing balances, or post adjustments.
Example result
This synthetic example shows the included check in use. Your agent uses its findings to complete your task report.
What you provide
Synthetic example records
| Starting record | amount: 100.00; unit: example units |
|---|---|
| Record to check | amount: 125.00; unit: example units |
What comes back
A difference needs review
- The recorded total does not match the starting amount.
- Expected
- 100.00
- Recorded
- 125.00
- Difference
- 25.00
This result comes from the checking tool in your download.
Read the source records
These are synthetic records from the bundled example.
- source-e1 · expected/e1
{"amount": "100.00", "id": "e1", "key": "customer + migration credit currency / SYNTHETIC-001", "unit": "synthetic-unit"} - source-o1 · observed/o1
{"amount": "125.00", "id": "o1", "key": "customer + migration credit currency / SYNTHETIC-001", "unit": "synthetic-unit"}
Checked values
- expected: 100.00; observed: 125.00; delta: 25.00; unit: synthetic-unit
Run this example
After purchase, extract the ZIP. Run these commands from the skill folder. Use a new output folder.
python3 scripts/checks.py
python3 scripts/audit.py assets/example.json \
--files-root assets/sample-files --output-dir example-resultExpected exit code: 1. Code 0 means no helper finding. Code 1 means a finding or review item. Code 2 means incomplete or invalid input.
The check uses the records you supply. Review each finding against the original documents.
What is saved
Ask your agent to save the completed task report in a folder you choose. The report template includes the result, source references, missing information, and next actions.
- A readable check report
- The local checking tool can save its findings as report.md.
- A data copy
- The same check can be saved as report.json for use in other tools. A local audit database is optional.

Collect the records
Start with old/new ledgers. Confirm the case, period, and source versions before the review.
Extract the task fields
Use customer, subscription, billing period, plan version, currency to keep records distinct. The agent records the original value, an exact quote, and the source location.
Reconcile the amounts
Add the observed amounts and compare the total with the supplied baseline. Run the Python helper on the structured records. Check each finding against its source.
Complete the report
Prepare the task result: credits lost or duplicated during transfer. Include missing evidence, unresolved questions, and the next action for each open item.
