  "name": "changed",
  "skill_md_contents": "---\nname: changed\ndescription: Sweep a corpus or jurisdiction for what has changed since a date. Subject: <YYYY-MM-DD> [corpus and/or state].\n---\n\nReport what changed since whichever subject the conversation is about. If it is not clear from the conversation, ask for it before calling anything.\n\nUse `search_us_statutes` with `changedSince`.\n\n1. **Scope it before you call.** Pass `corpusType` and `state`. A `changedSince` window matching more than 20,000 sections is **refused with a 422**, not truncated, because a partial change set would look complete to a sync job. If you get that 422, narrow the corpus or the date range; do not retry unchanged.\n2. Run the search. It costs 4 credits, and **an empty result is charged**: \"nothing moved since Tuesday\" is the answer you paid for.\n3. For anything that matters, call `get_section_changes` on the `act_id` (1 credit) to see the event history, then fetch the body if the user needs the current text.\n\nReport as a list grouped by corpus: citation, what kind of change, when it was detected.\n\nState these three caveats explicitly. They are the difference between a useful report and a misleading one:\n\n- **These are observed changes, not effective dates.** `detectedAt` is when we saw the publisher's text differ from our copy. It is an upper bound on when the change took effect, never the effective date.\n- **An empty result means no captured change in the window, never that nothing was amended.** Change capture began long after the corpus did, runs per source, and events are swept at 24 months. A date range older than 24 months will look quiet because the events were swept, not because the law was still.\n- **A detected change is not necessarily an amendment.** Publishers re-typeset and republish. If the user needs to know whether the substance moved, the diff has to be read.\n\nIf they ask \"has anything changed\" about one specific section rather than a corpus, skip all of this: `get_section_changes` on that `act_id` costs 1 credit and answers it directly.\n"
