Tool changes

  • submit_orderchangeddescription, annotations
    before

    Submit a real formation order to FilingDesk. THIS HAS A REAL-WORLD EFFECT: it creates an order and notifies a FilingDesk specialist. Only call after preview_order and after the user has explicitly confirmed the summary. Nothing is charged now — a specialist reviews the order, verifies the name, and emails a payment link. Returns the order reference.

    after · 58% of words in common

    Submits a formation order to FilingDesk. THIS HAS A REAL-WORLD EFFECT: it records the order, notifies a FilingDesk specialist, and may send an automatic order-confirmation email to the customer's email address. The specialist then reviews the order, confirms name availability and the price, and emails a payment link. Nothing is charged at submission. Call only after preview_order, once the user has explicitly confirmed that summary (userConfirmed: true). Returns the order reference (FD-…).

  • preview_orderchangeddescription, annotationsmeaning changed
    before

    Build an exact order summary WITHOUT submitting anything. No side effects. Validates the details, prices the order, and returns a confirmation summary. ALWAYS call this and show the user the returned summary before calling submit_order.

    after · 35% of words in common

    Validates and prices a formation order and returns the exact summary that would be submitted, WITHOUT submitting anything (no side effects). Use when the user wants FilingDesk to form their LLC or corporation and has provided the business name, state, entity type, and their name, email, and phone. The returned summary is meant to be shown to the user verbatim, and this step is required before submit_order.

  • compare_formation_optionschangeddescription, annotationsmeaning changed
    before

    Factual tradeoffs to help someone decide WHERE to form or WHAT entity type to pick. Returns fixed comparative facts and a required disclaimer — deliberately NOT a recommendation. Present the options neutrally, relay the disclaimer, and let the user choose; a FilingDesk specialist confirms the choice before anything is filed.

    after · 29% of words in common

    Returns fixed, factual tradeoffs for deciding WHERE to form (topic "state": the home state versus Wyoming, Delaware, and Nevada, including the cost of foreign-qualifying back into the home state) or WHAT entity type to use (topic "entity_type": LLC versus the S-corp tax election versus C-corp), plus a required disclaimer. Deliberately not a recommendation: the options are meant to be presented neutrally with the disclaimer, leaving the choice to the user. Use when the user asks which state to form in, whether to form out of state, or which entity type suits their business.

  • list_filing_stateschangeddescription, annotationsmeaning changed
    before

    What FilingDesk can do per state: which states it files in today with all-in pricing, which states have real name-checking, and confirmation that fee/deadline data covers all 50 states + DC. Call this before telling a user FilingDesk can file somewhere.

    after · 42% of words in common

    Lists FilingDesk's coverage: the states it files formations in today with all-in prices, the states its naming-rule screen supports, and fee/deadline data coverage (all 50 states + DC). Use when the user asks which states FilingDesk can file in, or before stating that FilingDesk can file in a particular state.

  • check_llc_namechangedtitle, description, input schema, annotationsmeaning changed
    before

    Check a proposed business name against a state's live registry. REAL results for Wyoming and Delaware only; Florida returns a Sunbiz search link; all other states return unsupported. A verdict is an indication, never a reservation — always show the returned note and verifyUrl.

    after · 22% of words in common

    Screens a proposed business name against state naming rules. It does NOT search any state registry and cannot tell whether a name is already taken. Wyoming and Delaware: the entity designator where the statute requires one (such as "LLC"), words that are restricted or need agency approval (such as "Bank"; in Wyoming also "Trust" or "University"), and other state-specific rules. Florida: the required designator only. Other states and DC return verdict "unsupported" with a note pointing to the state's official name search. Verdicts: "conflict" means the name as written breaks a rule that blocks filing, including a missing required designator (reasons include a "Try:" suggestion where one applies); "uncertain" means no blocking rule was found (reasons may still list warnings) and availability is unverified. Wyoming, Delaware, and Florida results include verifyUrl, the state's official name search. Use when the user proposes a name for a new LLC or corporation in Wyoming, Delaware, or Florida.

  • get_annual_report_deadlinechangeddescription, annotations
    before

    Work out when a state's annual report or franchise tax is next due, the amount owed, and the late penalty. States that key the deadline to the formation anniversary or quarter need formationDate; without it the tool says so instead of guessing a date.

    after · 54% of words in common

    Calculates when an LLC's next annual report or franchise tax is due in a given state and the amount owed, and returns the state's rule text, late-filing consequences where the dataset has them (penaltyAndNotes), and the official state source URLs. Use when the user asks when their LLC's annual report is due, how often it is filed, or what happens if it is late. States that key the deadline to the formation anniversary or quarter need formationDate; without it the tool says so instead of guessing a date.

  • compare_llc_costschangeddescription, annotationsmeaning changed
    before

    Rank states by what an LLC actually costs. Compares the one-time formation fee, the recurring state cost, and the combined first-year total. Use this for 'cheapest state to form an LLC' style questions rather than guessing.

    after · 29% of words in common

    Ranks US states by LLC cost: the one-time formation fee, the recurring state fee, or the first-year total (formation plus one recurring period). Use when the user asks which state is cheapest to form or maintain an LLC in, or wants LLC costs compared across specific states. Covers all 50 states + DC. State fees only — registered-agent fees, service fees, and revenue-based taxes are excluded. Returns figures only, without source URLs; get_llc_fees returns a state's official sources.

  • get_llc_feeschangeddescription, annotationsmeaning changed
    before

    Official LLC formation fee, recurring annual-report/franchise-tax cost, processing time, and known gotchas for a single US state, each with its source URL. Covers all 50 states + DC.

    after · 38% of words in common

    Returns one US state's LLC formation fee, its recurring annual-report or franchise-tax cost and cadence, online processing time, and known gotchas such as publication requirements, plus a labeled list of the official state source URLs the figures were taken from (dataset verified 2026). Use when the user asks what it costs to form or keep an LLC in a specific state. Covers all 50 states + DC.
