Who these tools help

Built for the people doing the work

90 skills across 14 toolkits, organized by the job in front of you rather than by technology.

Acquisition analysts and associates

Validate a deal package, build the pro forma, stress it, and write the IC memo with the Due Diligence, Underwriting, and Document Ingestion toolkits plus the sector packs.

Asset managers and owner-operators

Run budgets, monthly variance, collections, renewals, lease-up, capex programs, NOI improvement, hold-sell-refi decisions, and quarterly asset reviews.

Investment sales brokers

Take a seller-side assignment from intake and broker opinion of value through marketing, buyer process, bid leveling, negotiation, and closing coordination.

Lenders, credit analysts, and loan review

Screen and size loan requests, analyze sponsors and appraisals, write credit memos, monitor covenants, run annual reviews and risk ratings, and stress the portfolio.

Developers and construction lenders

Screen sites and entitlements, build budgets and yield on cost, size construction loans, review draws and GC contracts, track schedule risk, and model lease-up to stabilization.

Transaction counsel and closing teams

Review PSAs, title and survey, estoppels, loan documents, and insurance, prepare transfer documents, and manage the closing checklist and funds flow.

Proptech teams and AI builders

Study how deep domain expertise translates into structured skill files, knowledge bases, schemas, and a multi-agent orchestration architecture you can adapt.

Anyone learning commercial real estate

Every skill encodes an institutional analysis framework, and every benchmark traces to a cited research note, so the library doubles as a study guide.

Every skill in the library

All 90 CRE AI skills, by toolkit

Each toolkit installs as a Claude Code slash command and also works as individual Markdown files in Claude Projects, ChatGPT, Cursor, or any LLM. Every skill links to its source file on GitHub.

Frequently asked questions

Open-source CRE AI, answered

What is a CRE AI skill file?

A skill file is a plain Markdown document that tells an AI model exactly how to do one commercial real estate task: when to use it, what inputs to provide, the step-by-step strategy, the output format, quality checks, red flags, what to do when data is missing, and how to score confidence. Each of the 90 skills in CRE Agent Skills works on its own and links to the knowledge bases and research note behind it.

Which AI tools do the skills work with?

Any LLM tool that accepts a system prompt or project knowledge. Claude Code installs each toolkit as a slash command such as /cre-retail. Claude Projects, ChatGPT custom GPTs, Cursor, Windsurf, and direct API calls work by loading the Markdown file as instructions. No API keys, installation, or dependencies are required.

Are the repositories free to use commercially?

Yes. Both repositories are released under the Apache 2.0 license, so you can use, modify, and redistribute them, including inside a firm's internal tooling, as long as the attribution notice in each file stays in place.

What property types and roles are covered?

Multifamily acquisitions form the core. Additive packs cover industrial, office, retail, seller-side investment sales brokerage, post-closing asset management, cross-property capital markets and debt maturities, lender and credit work, and ground-up development and construction. Together that is 14 toolkits, 90 skills, and 35 knowledge bases.

How are the benchmarks and thresholds sourced?

Every skill and knowledge base added since Industrial v1 ships with a companion research note listing at least ten cited sources, at least three of them primary or quasi-primary, with publish and access dates. The library holds 93 research notes. Time-sensitive market numbers are labeled as directional and dated.

What is the difference between the Orchestrator and the Skills Library?

The CRE Acquisition Orchestrator is the full multi-agent pipeline: 31 named agent roles, phase dependencies, JSON schema data contracts, checkpoint and resume, and a live dashboard. CRE Agent Skills extracts the same domain expertise into standalone files you can use one at a time without adopting a system.

Which toolkit should I open first?

If a deal package just landed, start with Document Ingestion and Due Diligence. If a loan is maturing, start with Capital Markets. If you are on the lending side, start with Lender / Credit. If you are selling, start with Brokerage. If you are building, start with Development and Construction.

Can these skills replace an analyst, attorney, or lender?

No. The repositories are educational decision support. Every output is a draft for a qualified professional to review, and nothing in them is legal, tax, investment, accounting, or financing advice.

Built for adaptation

Want this adapted to your workflow?

The repos show the raw architecture. The consulting work is turning that architecture into your acquisition process, your documents, your underwriting standards, and your team's operating rhythm.

Educational and informational only. These repositories are not investment, legal, tax, accounting, or financial advice. Always consult qualified professionals before making real estate decisions.
