What the skill does

A routine your agent follows every time

Asks the right questions: State, project type, who hired you, first and last delivery dates, and yes, no or unknown answers about events that can move a deadline.
Gets the dates from LienDeadline: Uses the LienDeadline tools when they're connected, or the public API directly. No account or key.
Shows its work: Every deadline comes with its status, the statute behind it, and any warnings or assumptions.
Flags instead of guessing: A missing fact, an unknown answer or an uncovered case returns “needs review” with the reason, never a made-up date.
Points you to the rules: Links the state's lien guide so you and your counsel can check the details.

Example

An unknown fact is flagged, not guessed

A follow-up on a Florida job where the supplier doesn't know one fact.

The Notice to Owner is not calculated and needs review because the owner's final-payment disbursement is not established; the claim of lien deadline is still calculated as Dec 9, 2026, under Fla. Stat. § 713.08(5). — Real output from the hosted connector, October 2026. An educational baseline, not legal advice.

Coverage

What it calculates today

The skill checks what's live for your project, so you never get a date for a state that isn't ready.

Calculated supplier deadlines: Preliminary notice and lien filing for Florida and Kansas private projects.
More states: Added as each state's reviewed rules are released.
Everything else: Returns “needs review” with the reason: other states, public projects and any deadline that depends on a fact you don't know.
Lien guides: All 50 states and DC, with statute citations.
Invoice-based deadlines: Available with a customer API key through the local MCP server.
