Web & Frontend

docyrus Bundle

Build Docyrus React TypeScript web applications end-to-end, combining authentication, API access, @docyrus/app-utils runtime helpers, @docyrus/devtools in-app debugging, generated collections, TanStack Query/Form patterns, and production-grade UI implementation with preferred component libraries. Use when creating or modifying Docyrus-backed apps that use @docyrus/api-client, @docyrus/signin, @docyrus/app-utils, @docyrus/devtools, Docyrus collections, queries, dashboards, forms, tables, layouts, or Docyrus UI components.

docyrus Bundle

Design, validate, and test a Docyrus email template end-to-end using the `docyrus studio` email-template CLI commands. Use when the user wants a reusable, data-bound email — a templated subject + HTML/text body with record placeholders ({{field}} Handlebars) that an automation send-email node (or a manual send) fills from a record. Covers writing the subject/body with the record context, optionally binding the template to a data source, and proving the template renders/sends. Triggers on "create an email template", "design a templated email", "email with record fields merged in", "notification email body", "studio create-email-template", or any email-template authoring + validation task in Docyrus. For HTML/PDF print/report templates use docyrus-print-pdf-template-design; for the automation that sends the email use docyrus-automation-design.

docyrus Bundle

Design, configure, validate, and test Docyrus data views (saved grid/gallery views) with the `docyrus studio` data-view CLI commands. A data view is a named saved configuration of how one data source's records are presented — visible columns, order/pinning/grouping, row height, table/gallery display, sorting, filters (column filters + react-querybuilder query), quick-filter fields, row/cell color rules, paging, inline editing, and a bound form. Use when creating or editing a saved view / tab / list view, hiding or reordering columns, setting a default filtered/sorted view, grouping rows, adding color rules, configuring paging or inline editing, or binding a form to a view. Triggers on "create a data view", "saved view", "add a grid tab", "default view", "filter/sort a view", "hide columns", "group by", "color rules", "gallery view", `docyrus studio create-data-view`, `update-data-view`, `list-data-views`. For the schema use docyrus-data-source-design; for the React grid UI use docyrus-data-grid-page-design.

docyrus Bundle

Design, validate, and test a Docyrus HTML/PDF print/export (report) template end-to-end using the `docyrus studio` html-template CLI commands. Use when the user wants a printable/exportable document rendered from a record — an invoice, quote, receipt, report, certificate, packing slip — authored as HTML + CSS with {{field}} Handlebars placeholders, with page setup (orientation, format, margins, header/footer, filename) and a data-source binding, then rendered to HTML/PDF for a record. Covers writing the body/header/footer/styles, the page options, marking a default template, and rendering it against a real record to prove it works. Triggers on "create a PDF/print template", "design an invoice/quote/report template", "printable document from a record", "export to PDF", "studio create-html-template", or any print/PDF report-template authoring + validation task. For emails use docyrus-email-template-design; for the automation that generates a document use docyrus-automation-design.

2ykwang Bundle

Generate an interactive single-file HTML visualization — mockup, wireframe, ERD, flowchart, chart, slides, architecture diagram, dashboard, timeline, mindmap, kanban, or table. Use when the user wants something rendered rather than described: a UI mockup or wireframe, a database schema as an ERD, business logic as a flowchart, data as a chart, or content as slides. Also use when they point at a file (schema, spec, data) and ask to see it visualized.

2ykwang Bundle

Turn code, specs, a PR, or the current conversation into a QA test-case list a non-developer can read and run, exported as CSV, a shareable HTML report, or both. Trigger when the user wants QA test cases, a test plan, a QA checklist, or a test-case CSV/HTML (e.g. "write test cases for this", "make a QA list"). Output uses behavior-and-scenario language, never code symbols like function names or file paths. Not for writing or running automated test code (pytest/jest), code review, or test-strategy docs.

2ykwang Bundle

Render an interactive HTML board for the user to pick among multiple comparable options side-by-side at once — engineering trade-offs, copy audits, action-item triage, architecture decisions, policy calls. Returns the picks (and optional hold/note flags) as a JSON file the agent can apply.

2ykwang Bundle

Change one condition an agent runs under (instruction text, the reference material instructions point at, MCP tools and permissions, hooks, skill files), then run the same prompts before and after, several times each, to see what actually changes. Produces an HTML report showing both arms' answers side by side. Use when deciding whether to add a rule, when you need evidence that an existing rule can be deleted, when picking between two wordings of the same rule, or when checking whether material you placed is actually being read. Triggers on 'does this rule do anything', 'compare before and after adding this', 'can I drop this', 'difference with and without this', 'run an A/B'. Not for application code changes or anything automated tests already verify. Built on Claude Code: it spawns `claude -p` subprocesses to run both arms.

2ykwang Bundle

Turn code changes into a single-file HTML code review report that pairs the diff with context a diff can't show — design decisions, rejected alternatives, tradeoffs, unfinished work — plus prioritized review points. Use when preparing for review after finishing a sizable change, refactor, or feature, or whenever the user asks for a review report, change report, or an HTML summary of their changes.
