Tool changes

2026-10-04simulate_scanchangeddescription, input schema, annotations
before
Dry-run a routing program against a fake scan context.
after · 50% of words in common
Dry-run a routing program against a sample scan context. Does not create a scan or change a code.
2026-10-04set_routingchangeddescription, input schema, annotationsmeaning changed
before
Compile plain English into a routing program and save it on a claimed code.
after · 29% of words in common
Legacy Programmable tool: compile a plain-language routing prompt or save a valid supplied routing program on an owned code. Version conflicts require reading again.
2026-10-04check_qr_linkadded
Check a public QR destination's current HTTP reachability, redirect chain and known general provider policies. Cannot determine exact expiry, account state or destination safety.
2026-10-04render_qrchangeddescription, input schema, annotationsmeaning changed
before
Return PNG/SVG render URLs for a code.
after · 13% of words in common
Preview and download an owned QR as PNG, or eligible SVG. Returns a short-lived download URL; do not expose private connection tokens. Existing anonymous PNG URLs remain supported.
2026-10-04compare_qr_codesadded
Compare aggregate human scan counts for 2 to 10 owned QR codes over the same period. Do not infer conversion rates without separate conversion data.
2026-10-04get_analyticschangeddescription, input schema, annotationsmeaning changed
before
Read scan counts for a claimed code.
after · 10% of words in common
Read aggregate recorded human scans for one owned code. Default period is 28 days; history follows the current plan. Scans are not conversions or unique people.
2026-10-04update_destinationchangeddescription, input schema, annotationsmeaning changed
before
Update a claimed QR destination URL.
after · 10% of words in common
Change an owned QR destination without changing its printed redirect URL. Confirm the intended destination with the user. Supply expected_revision from get_qr_code; conflict means read again before retrying.
2026-10-04get_qr_codeadded
Inspect an owned QR code, destination, design, latest stored link health and revision. Read before updating.
2026-10-04list_qr_codesadded
Find only your owned QR codes, with label search and stable cursor pagination.
2026-10-04get_accountadded
