### Tool changes

- 2026-10-10 `get_booking_link` changed (title, description, inputSchema, outputSchema, annotations) **meaning changed**
  - before: Get the official booking page for one US backcountry permit or one campground, with the dates filled in where the booking site allows it. Use it when the person is ready to book or apply. It only returns a link and a sentence about it; it does not book, pay or enter a lottery.
  - after: Returns the link to the official booking page for one US backcountry permit or one campground. For some permits the link also carries the first date and the number of people you give, but the booking site may not use them, so the person checks or picks the dates and group size on that page. For a campground, the person picks or checks the dates on the booking page. For some places it returns the agency's own page or the PermitSnag page instead of a booking page. It only returns a link and a sentence about it; it does not book, pay or enter a lottery.
- 2026-10-10 `check_availability` changed (description, inputSchema, outputSchema) **meaning changed**
  - before: Check what PermitSnag has recorded for one US backcountry permit or one campground on specific dates, up to 62 days. Use it when someone asks whether a permit or campsite is open or available on certain dates. Answers come from PermitSnag's own recent checks of the booking site, each with the time it was checked; it is not a live look, and nothing is booked. A date we have not checked recently comes back as unknown, never as sold out. Also says when dates are not on sale yet, out of season or closed.
  - after: Shows what PermitSnag has recorded for one US backcountry permit or one campground over a range of up to 62 days. Answers come from PermitSnag's own stored checks of the booking site, not a live look, and nothing is booked. Each date has one state: observed_opening (an opening seen recently, with when it was last seen), observed_no_match (a recent check that saw no opening, with its time), stale (the newest check is older than staleAfterHours, with its time), unknown (no usable check of that date), unreleased (not on sale yet, by the agency's release rule or the booking site), off_season (outside the agency's published season), closed (closed by the agency) or unsupported (PermitSnag does not check this place). Neither stale nor unknown means sold out. Permit dates are shown as they stood 15 minutes ago. For a permit split into zones or entry points, our checks may cover only some of them, so a date with no opening seen comes back as unknown, never as observed_no_match.
- 2026-10-10 `get_campground_details` changed (outputSchema)
- 2026-10-10 `search_campgrounds` changed (outputSchema)

## Tools (6)

- `check_availability`: Shows what PermitSnag has recorded for one US backcountry permit or one campground over a range of up to 62 days. Answers come from PermitSnag's own stored checks of the booking site, not a live look, and nothing is booked. Each date has one state: observed_opening (an opening seen recently, with when it was last seen), observed_no_match (a recent check that saw no opening, with its time), stale (the newest check is older than staleAfterHours, with its time), unknown (no usable check of that date), unreleased (not on sale yet, by the agency's release rule or the booking site), off_season (outside the agency's published season), closed (closed by the agency) or unsupported (PermitSnag does not check this place). Neither stale nor unknown means sold out. Permit dates are shown as they stood 15 minutes ago. For a permit split into zones or entry points, our checks may cover only some of them, so a date with no opening seen comes back as unknown, never as observed_no_match.
- `get_booking_link`: Returns the link to the official booking page for one US backcountry permit or one campground. For some permits the link also carries the first date and the number of people you give, but the booking site may not use them, so the person checks or picks the dates and group size on that page. For a campground, the person picks or checks the dates on the booking page. For some places it returns the agency's own page or the PermitSnag page instead of a booking page. It only returns a link and a sentence about it; it does not book, pay or enter a lottery.
- `get_campground_details`: Get the details of one US campground: its booking system, how far ahead sites go on sale, site count and types, stay limits, season and closures. Use it after search_campgrounds, or when the person names a specific campground. Says whether PermitSnag can send an alert when a site opens, and whether our checks count individual sites or only the campground as a whole.
- `get_permit_details`: Get the rules for one US backcountry or wilderness permit: how it is issued (reservation, lottery or in person), its season, lottery and release dates, closures, group size limit, and the official agency page. Use it after search_permits, or when the person names a specific permit. Every date comes from an agency source; a date we cannot source is left out. Says whether PermitSnag can send an alert when the permit opens.
- `search_campgrounds`: Find campgrounds in the US by name, area or state, across Recreation.gov and state park booking systems. Use this when someone wants a place to camp or asks about a specific campground. Returns up to 10 campgrounds with their PermitSnag page, their booking system, and whether PermitSnag can send an alert when a site opens. It does not check dates; use check_availability for that.
- `search_permits`: Find US backcountry and wilderness permits by name, park, trail or area, for hikes, climbs, river trips and overnight trips in national parks, national forests and state parks. Use this when someone asks how to get a permit or which permit a trip needs. Returns up to 10 permits with their PermitSnag page and whether PermitSnag scans them for cancellation openings. It does not check dates; use check_availability for that, and get_permit_details for the rules of one permit.
