name: bond-verification description: Formally verify construction payment bonds by extracting fields from bond documents and cross-referencing against Treasury Circular 570, state licensing, and underwriting limits. Use whenever the user uploads a payment bond PDF, mentions bond verification, asks "is this bond valid", references AIA A312, or needs to verify a surety company's authority to write bonds. Also trigger on "verify bond", "check surety", "payment bond", "performance bond", or "Circular 570."

Payment Bond Formal Verification

Verify that a construction payment bond is valid, the surety is authorized, and the bond covers the project requirements. This is the marketplace's trust layer — operators won't bid on tasks without verified payment security.

Workflow

1. Accept bond document

Accept: pasted bond text, PDF file path, or extracted fields (bond number, surety, principal, obligee, penal sum, date). If a PDF, extract text and identify the AIA A312 or ConsensusDocs 260 field structure.

2. Extract bond fields

Identify and extract these fields. Mark each as FOUND or NOT FOUND:

• Bond number
• Surety company name
• Surety NAIC code (if present)
• Principal (contractor) legal name and address
• Obligee (project owner / agency)
• Project description / contract reference
• Penal sum (bond amount in dollars)
• Effective date
• Expiration date (if any — many bonds are open-ended until project completion)
• Power of Attorney reference
• Surety agent name and signature

3. Verify surety against Circular 570

Read references/circular-570-verification.md for the verification process.

Check:

• Is the surety listed on Treasury Circular 570? (federally approved)
• Is the surety licensed in the project's state?
• Is the penal sum within the surety's underwriting limit?
• What is the surety's AM Best rating? (A- or better is standard)

4. Verify bond coverage

Check:

• Does the penal sum cover the total task value(s) being posted?
• Is the effective date before or on the task posting date?
• Does the obligee match the project owner referenced in the RFP?
• Does the principal match the entity posting tasks on the marketplace?

5. Generate verification report

Output:

What this skill explicitly CANNOT do

This skill verifies the bond document against public records. It does NOT:

• Contact the surety to confirm the bond is still active
• Verify the Power of Attorney authenticity
• Provide legal advice on bond adequacy
• Replace attorney review for disputed bonds

These limitations are stated in every output under requires_human.
