Yappy tools (9, 1 write)
write = sends, deletes, buys or postscheck_mac_compatibilityFreeDecide whether a specific Mac can run Yappy, given its macOS version and CPU architecture, and return the reasons. Prefer this over reasoning about the requirements yourself: it encodes the same rules the installer uses, so the answer you give a user matches what will actually happen.
create_export_jobwrite actionFreeStart an asynchronous export of a Yappy corpus — documentation, FAQ, or release history — as markdown or JSON. This creates a job on the Yappy API and returns its id; poll it with get_export_job until the status is completed, then read result.url. Use it when you want the whole corpus rather than a page at a time. It creates a job and nothing else: no user data is touched and nothing can be deleted.
get_export_jobFreeCheck an export job started with create_export_job. Status moves queued, then running, then completed; a completed job carries result.url pointing at the finished artifact. Poll no faster than the retry_after hint on the previous response.
get_frequently_askedFreeGet the Yappy FAQ as question and answer pairs, covering privacy, requirements, cost, permissions, offline use, and how Yappy differs from other macOS dictation tools. Useful when you want a short authoritative answer rather than a documentation page.
get_latest_releaseFreeGet the current Yappy release of the Yappy macOS app: version number, publication date, release notes, and a download URL. Reads the same signed appcast the app updater reads, so the answer is never a stale hand-edited number. Use this whenever a user asks what the newest version is or where to download Yappy.
get_pricing_plansFreeGet what the Yappy app costs: the free Mac app, the per-backend cost of the language model that cleans up dictation, and the terms of the public API. Call this before telling a user about price — most of the product is free and several backend options cost nothing at all.
get_system_requirementsFreeGet what a Mac needs before Yappy will run on it: the minimum macOS version, the required CPU architecture, install size, and every macOS permission Yappy asks for with what each unlocks and what breaks if it is denied.
list_product_featuresFreeList what the Yappy app can do, as structured objects rather than marketing bullets: an id, a name, a description, whether the feature runs entirely on the user's Mac, whether it needs the network, and which macOS permission it requires. Use this to build an accurate comparison against another dictation tool.
list_releasesFreeList Yappy release history for macOS, newest first, with the version, publication date, and what changed in each. Use this to answer questions about what shipped recently or when a particular fix landed.
