Free, and about thirty seconds: a work email and a six-digit code.

Downloading shares your name, firm, role, and email with The Helvetica Group. That introduction is what keeps every skill here free.

What this skill does

Checks out the contractor who will actually spend your construction money — license, insurance, past work, how many jobs they already have going, the contract, and any liens or lawsuits — and gives you a rating and a list of what to require before closing.

What it does

  • Walks through license and business-entity verification at the source, and checks that every name matches
  • Reviews insurance certificates and lists what to confirm with the agent
  • Checks completed projects and gives reference questions that surface real problems, including calls to suppliers
  • Compares the contractor's current workload with the size of this job
  • Explains who carries cost-overrun risk under the contract type, and sets out the lien, judgment and lawsuit searches to run on past jobs

When to use it

  • A construction or rehab loan is in underwriting
  • The borrower is using a contractor you have not worked with
  • The borrower wants to act as their own general contractor
  • You need a replacement contractor on a stalled project

What to have ready

  • The contractor's exact legal name and license details
  • Certificates of insurance
  • The bid or construction contract
  • A list of completed and current projects

How to use it

  1. Download it with the button above. You'll sign in with a work email — that's how the creator knows who is using their skill.
  2. Copy the install prompt from the "Run it in Claude" box, and paste it into Claude along with the file. Claude installs the skill, fills in your firm's details where the file has [BRACKETED] placeholders, and runs a quick test with you.
  3. Then just ask in plain English. Claude picks the skill up on its own when a request matches it. Anything it still needs, it asks you for — it won't invent a number.

"Vet [CONTRACTOR NAME] for the [PROJECT TYPE] at [ADDRESS] — bid is [AMOUNT], license [LICENSE NUMBER] in [STATE], COI attached."

What you get back

A contractor vetting report rated acceptable, acceptable with conditions, or not acceptable, showing what was verified and where, what was not checked, numbered conditions, and a draft request list for the borrower.

Good to know

  • Output quality tracks input quality. A missing figure is flagged as missing — it is never estimated to fill a gap.
  • Every draft is a starting point for your own review, not a finished decision.
  • Runs anywhere Claude does: the Claude app, Claude Desktop, or Claude Code.
  • It treats licensing, insurance exemptions and lien rules as state-specific, and marks any search not actually run as not checked rather than clear.

Legal disclaimer

This skill drafts; it does not decide. Its output is not legal, tax, accounting, appraisal, or investment advice, and using it creates no attorney-client, fiduciary, or advisory relationship. Nothing it produces is a commitment to lend or an offer to sell a security. Verify every number, date, citation, and conclusion against the source documents, and have a qualified professional licensed in the relevant jurisdiction review the work before you rely on it or send it to a borrower, investor, counterparty, or regulator.

Skill name
contractor-vetting-checklist
What it does
Use when a lender or broker needs to vet the general contractor on a construction or rehab loan before closing. Trigger on "vet the GC," "check out this contractor," "is this builder licensed," "verify the contractor's insurance," "contractor due diligence," "GC questionnaire," "can this contractor handle the job," "how many jobs do they have going," "fixed price or cost plus," "any liens or lawsuits against the contractor," "the borrower is acting as their own GC," or when a contractor bid, license number, certificate of insurance, or builder resume is dropped on a file. Checks license, insurance, references, past projects, capacity, contract terms, and lien and litigation history, and returns a vetting report with an ACCEPTABLE / ACCEPTABLE WITH CONDITIONS / NOT ACCEPTABLE rating plus a request list for the borrower. Draft only; the lender makes the call.

Contractor Vetting Checklist

On a construction or rehab loan the lender is underwriting two borrowers: the one who signs the note and the one who actually spends the money. A strong sponsor with a weak contractor still ends in a stalled job, a pile of subcontractor liens, and a cost-to-complete nobody budgeted. Most contractor failures were visible before closing — an expired license, a certificate of insurance for the wrong entity, six jobs running with one superintendent, or a "fixed price" contract with every risky item carved out as an allowance. This skill checks those things in order and tells the lender what to require.

Works for: general contractors and builders on ground-up, heavy rehab, and fix-and-flip loans, and borrowers acting as their own general contractor. Pair it with ground-up-construction-underwriter at underwriting and stalled-project-rescue-plan when vetting a replacement contractor.


Step 1 — Intake

InputRequired?Notes
Contractor legal name and entity✅Exact name — the license, insurance, contract, and bank account must all match it
Project and scope✅Type, size, budget, schedule; the job the contractor is being vetted for
License information✅License number, issuing agency, classification. Verify with the agency, not from a document
Certificates of insurance✅General liability, workers' compensation (or exemption), auto; umbrella if any
Bid or construction contract✅Price, contract type, schedule, allowances, exclusions, change-order and payment terms
Completed-project list✅Addresses, size, completion dates, owner or lender contacts
Current jobs✅Every active job, size, stage, and who supervises it
ReferencesHelpfulAt least two owners or lenders and two suppliers or subcontractors (illustrative default)
Relationship to borrower✅Arm's length, affiliated, or the borrower itself
Contractor financialsHelpfulFor larger jobs: financial statements, bank reference, or bonding capacity

Minimum viable: exact legal name, license details, insurance certificates, and the bid or contract. Without the contract you cannot judge who carries overrun risk — say so.


Step 2 — License and entity

Licensing is set by each state and sometimes by the city or county, and some jurisdictions do not
