Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00187 | $0.07510 |
| Opus 5 | $0.00093 | $0.03755 |
| Sonnet 5 | $0.00037 | $0.01502 |
| Haiku 4.5 | $0.00019 | $0.00751 |
Grade A, and why
probate-property-finder scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 625 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Probate Property Finder
When a real estate investor pulls probate filings from a county, they often get only the case number, decedent name, date of death, and executor contact information — but no property address. This skill bridges that gap by researching what real property the decedent actually owned and producing a clean, upload-ready CSV for REI Sift.
This skill focuses exclusively on property discovery and data enrichment. It does NOT
identify decision-makers, skip trace heirs, or do deep prospecting — the deep-prospecting
skill handles that separately once you have an address.
Critical Principle: Actually Browse the Sites
The single most important thing this skill does is use browser tools to navigate county assessor and recorder websites and execute searches. Do not merely identify URLs or list them as resources — you must actually open the browser, navigate to the site, type in search terms, read the results, and extract data from the pages.
If a county assessor site is broken, unresponsive, or returns no results, immediately pivot to the county recorder/deed search. If that fails, use aggregator sites. But always start by actually browsing the official county data source.
Aggregator sites (Zillow, NeighborWho, Spokeo, etc.) are for cross-referencing only — never treat them as primary sources. They often have stale or incorrect ownership data. The county assessor is the source of truth for current ownership, and deed records are the source of truth for ownership history.
Input Formats
The skill accepts two input modes:
Single Record
The user provides details about one probate case in conversation:
- Decedent name (required)
- County/state where probate was filed (required)
- Case/file number (helpful but optional)
- Executor name and address (helpful for cross-referencing)
- Date of death (helpful for narrowing searches)
Bulk CSV
The user uploads a CSV file containing multiple probate records. The CSV may have varying column names, but typically includes some combination of:
- File/case number
- Deceased/decedent name
- Date of death/deceased
- Executor/PR name
- Executor address (street, city, state, zip — may be separate columns or combined)
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

probate-property-finder is a skill published in the GitHub repository DataSift-Ty-Personal/SiftStack (21 stars, last pushed 5d ago), licensed MIT. It adds 187 tokens to every session and 7,510 once invoked, about $0.0009 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
