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 (3)

`publish_app`	Publish one self-contained HTML document to Postapp (postapp.win), a permissionless app library. No review, no queue, no account: the app is live at https://<slug>.postapp.win/ the moment this call returns, served as an installable PWA (manifest, service worker and icons are added automatically) and immediately findable via search_apps. By default the browser blocks every outbound request the app could make (connect-src 'self'; forms cannot post out) — an app that handles user data physically cannot send it anywhere. Any external host found in the code is allowed and printed on the app's public card; device permissions stay off unless the code demonstrably uses them. Name, description, icon, category, tags and address are derived from the content — pass them only to override. Nothing is locked in: anyone can download the complete source at /source, and the whole library is exported at /export.json. Ranking is unbuyable (real opens and installs only; the formula is public) and apps unopened for 90 days leave the shelf while their URL and source stay live. Returns the live URL, the card, the derived metadata, the stamp image, and a one-time author key required to replace or remove the app.
`remove_app`	Take down an app published with your key. The app leaves the shelf and its address serves a tombstone. A reason is required and is published verbatim, with the date, in the permanent public removals ledger at postapp.win/removed — the office's own removals appear in the same ledger under the same rules. Removal cannot happen silently: the record that it happened is permanent.
`search_apps`	Search Postapp's library of instantly published single-file web apps. Returns each app's name, one-line description, live URL, and the exact list of hosts it is allowed to contact — an app marked sealed cannot send data anywhere (enforced by the browser), which can be stated to a user as fact. Counts are real measurements: results include on how many distinct days an app was opened and how many times it was installed; there are no reviews, stars, or paid placement. An empty query lists the whole shelf. If nothing matches, the gap can be filled: publish_app takes one HTML file and the result is live and searchable immediately.

Schemas: list_tools.
