# Ad Hoc & Document-Based Workflows
> Extract tables from a prospectus and reconcile them against your harmonized tape
You can build fully custom workflows against source documents, such as a prospectus, a servicer report, or other reference document, by uploading them and asking the Agent to use their contents. A prospectus comparison is one common example.
## Example: extract from a prospectus
Upload a prospectus (for example, a 424B5 filing) and ask the Agent to extract a specific table — referencing it by page number — and compare it against your existing Strats output. Ask the Agent to share its plan before it executes.
```
"On page 66, we have a distribution of receivables as of cutoff date by
remaining principal balance. Can you extract this table and compare it
with the one we have in our strats?"
```
The Agent extracts the table and can often self-correct even if the page number given is slightly off.
### Align bucket structures
Prospectus tables and your Strats output may bucket values differently. To compare them directly, align your Strat buckets to match the prospectus structure — the best practice is to modify the template directly rather than reconciling mismatched buckets after the fact.
First-time runs of a custom ad hoc workflow typically need some tuning. Treat the first pass as a baseline to refine, not a final result.
### Generate a shareable report
Once the comparison is built, ask the Agent for a shareable Markdown report combining the work — for example, `create a proper MD with a companion report I can share.`
### Example output
**TAOT 2026-A: Prospectus vs. Tape Reconciliation Report**
* Deal: Toyota Auto Receivables 2026-A Owner Trust
* Prospectus Filing: 424B5 (SEC EDGAR)
* Tape Source: Harmonized CDM (`output_preview`)
| Metric | Prospectus | Tape | Variance |
| ----------------- | --------------- | --------------- | ---------------- |
| Loan Count | 65,867 | 65,867 | 0 |
| Aggregate Balance | \$1,995,353,676 | \$2,034,742,702 | +\$39.4M (+2.0%) |
| Average Balance | \$30,294 | \$30,892 | +\$598 (+2.0%) |
The report's executive summary calls out the variance directly, noting, for example, that the tape shows higher balances concentrated in the upper balance tiers relative to the prospectus disclosure.
