Write and reconcile the design document for a significant xmris change — the reader-facing explanation of why a decision was made. Use at the START of any change that adds vocabulary or a contract, picks between viable approaches, or spans multiple PRs; and again at the END of that work to reconcile the doc against what was actually built.
Add a new xmris processing/accessor function end-to-end following the project's architectural rules. Use when adding a new `.xmr` method or transform (e.g. a new apodization, phasing, Fourier, baseline, or fitting operation), or when asked to "add a processing function/method" to xmris.
Add or modify an xmris interactive visualization widget (AnyWidget) end-to-end following the project's conventions. Use when adding a new `.xmr.widget.*` component (e.g. a phaser, scroller, apodizer, or other canvas UI), or when working on an existing widget's Python/JS/CSS, accessor wiring, or docs.
Create or edit an xmris documentation notebook (MyST .md under docs/notebooks/) following the project's notebook conventions. Use when adding a tutorial/doc page, writing notebook tests for a function, documenting a new .xmr method, or restructuring existing doc notebooks.
Cut an xmris release — bump the version, run the full CI matrix via a release branch, and tag to trigger the PyPI publish. User-triggered only.
