Tool changes

No tool definition changes recorded. A server's first observation is its baseline; later probes record what changes.

Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

Tools (8)

`add_business_days`read-only	The date that is days business days after start. The start date is day 0, matching Excel WORKDAY, so days=1 always leaves the start date. days is an integer from -3660 to 3660. Omit calendar for us-federal-opm. us-fed-banking keeps Reserve Banks open on the Friday before a Saturday holiday.
`count_business_days`read-only	How many business days are in the inclusive span from start through end, matching Excel NETWORKDAYS. Negative when end is earlier. The span must be 3660 days or less. Omit calendar for us-federal-opm.
`frcp_6a_deadline`read-only	Count a period stated in days under Fed. R. Civ. P. 6(a)(1). Exclude the trigger day. Count every calendar day, including intermediate Saturdays, Sundays, and legal holidays. Roll only the last day. direction is after or before. days is an integer from 1 to 3660. There is no calendar argument. Legal holidays are the Rule 6(a)(6)(A) days on the federal-office observed weekday, including Juneteenth. This is not Excel WORKDAY. It does not apply state holidays, one-off holidays, clerk inaccessibility, Good Friday, or Inauguration Day, and it does not decide whether a filing is timely.
`is_business_day`read-only	Whether a civil date is a business day, and why. Omit calendar for us-federal-opm (US federal offices). us-fed-banking is the Federal Reserve Banks schedule: a Saturday holiday does not close the preceding Friday. us-nyse is NYSE full-day holidays for 2026 through 2028. us-sifma is SIFMA recommended U.S. fixed-income full closes for 2026 and 2027. An early close stays open. us-ca is California state offices for 2026. Farmworkers Day is closed. Friday, July 3, 2026 stays open. us-ny is New York State executive-branch offices for 2026 and 2027. Friday, July 3, 2026 stays open. Election Day 2026 stays open. us-nyc is New York City offices for 2026 and 2027. Friday, July 3, 2026 is closed. Election Day 2026 is closed. The result includes calendar, sources, and disclaimer. Not legal, payroll, or financial advice.
`list_calendars`read-only	Shipped calendars: id, name, source URL, Saturday and Sunday rules, coverage, last verified, and changelog. us-federal-opm is the default. us-nyse covers 2026-01-01 through 2028-12-31. us-sifma covers 2026-01-01 through 2027-12-31. us-ca covers 2026-01-01 through 2026-12-31. us-ny covers 2026-01-01 through 2027-12-31. us-nyc covers 2026-01-01 through 2027-12-31.
`list_holidays`read-only	Holiday rows for one year. us-federal-opm and us-fed-banking return the eleven nationwide legal public holidays. On us-fed-banking, observed is null when the legal date is a Saturday, because Friday stays open. us-nyse returns the NYSE full-day table and accepts only 2026 through 2028. us-sifma returns the SIFMA U.S. full-close table and accepts only 2026 and 2027. us-ca returns the California state-office table and accepts only 2026. us-ny returns the New York State office table and accepts only 2026 and 2027. us-nyc returns the New York City office table and accepts only 2026 and 2027. A Saturday holiday closes Friday. year is 2021 through 2100 on the federal calendars. Years after 2030 use the same rules and are not a later official table.

The result is accepted true and applied false. claim is one line of at most 500 characters. source_url is an http or https URL with no username or password. Do not send a name or an email. This is not a calculation.
`roll_date`read-only	Stay on date when it is already a business day. Otherwise move to the nearest business day in direction next or previous. This is not Excel WORKDAY, and it does not decide whether a filing is timely. Omit calendar for us-federal-opm.
