sift-operations is a skill for Claude Code, Codex from DataSift-Ty-Personal/SiftStack. It costs 173 tokens per session (3,319 once invoked), scanned A, original, MIT.

A workflow for finding active real estate buyers in a US county and researching the people behind companies such as LLCs, trusts, and corporations. Skip tracing means finding contact information for those people.

In plain words
What is it for?

Why use it?
It turns broad buyer records into a more usable list of investors and decision-makers who may be interested in properties.

Token cost

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.

Security

Grade A, and why

sift-operations 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 4d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/datasift_core.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 — 250 lines — stays where its author put it; the contents beside it link to each section on GitHub.

REI Sift Operations Encyclopedia

Complete operational knowledge base for REI Sift (DataSift.ai). Covers sequences, filter presets, niche/bulk sequential marketing, SiftLine boards, drip campaigns, events/tasks, daily operations, and troubleshooting.

When to use this skill: Any time a user asks about configuring, building, troubleshooting, or understanding workflows inside REI Sift. This includes sequence setup, preset building, board management, lead pipeline configuration, daily operational routines, team setup, and import workflows.

Execution Mode Detection

This is a routing/reference skill that directs to other skills for implementation. When Playwright automation is available (Claude Code CLI with DATASIFT_EMAIL/DATASIFT_PASSWORD set), the following companion skills provide automated execution:

Task Companion Skill Automation Script
Filter preset management sequential-presets.skill sequential-presets/scripts/manage_presets.py
Sequence creation sift-sequences.skill sift-sequences/scripts/manage_sequences.py
Phone tag upload phone-validator.skill phone-validator/scripts/upload_phone_tags.py
Market research sift-market-research.skill sift-market-research/scripts/extract_market_finder.py

Those scripts live in the companion skill, not in this plugin. Each one uses scripts/datasift_core.py for login, cookie persistence, and popup dismissal, and this plugin ships its own copy of that helper. Credentials are loaded from .env or environment variables, never hardcoded.

How to Use This Skill

When a user asks a Sift question:

  1. Identify the domain -- determine which area of Sift the question falls into
  2. Load the right reference -- read the appropriate reference file(s) for detailed configurations
  3. Respond in hybrid format -- give a brief concept explanation, then provide the step-by-step walkthrough
  4. Generate docs when useful -- for complex preset maps or sequence plans, create a markdown or Excel file the user can keep
  5. Fall back gracefully -- if the question doesn't match a specific category, start with general-operations.md and the Core Concepts section below

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.
