Build and customize EmDash CMS sites on Astro. Use when creating pages, defining collections, writing seed files, querying content, rendering Portable Text, setting up menus/taxonomies/widgets, configuring deployment, or any task involving an EmDash-powered Astro site. Assumes basic Astro knowledge but provides all EmDash-specific patterns.

Create EmDash CMS plugins with hooks, storage, settings, admin UI, API routes, and Portable Text block types. Use this skill when asked to build, scaffold, or implement an EmDash plugin, or when creating plugin features like custom block types, admin pages, or content hooks.

Review one pull request for real bugs, regressions, and convention violations. Enumerate candidate issues across the whole diff, verify each against the code, then return structured line-anchored findings and a verdict. Read-only on GitHub; the orchestrator posts the review.

Trace from a reproduced symptom to the source code that causes it. Identify the specific file and approximate line, then rate confidence honestly.

Write the fix when verify says bug and diagnose says high confidence. Follow EmDash conventions, confirm the reproduce test now passes, run lint and typecheck, stage but do not commit.

Decide whether the diagnosed behaviour is actually a bug or whether the code is doing what it was designed to do. Gate the fix stage.

Reproduce an EmDash admin UI bug. Boots a demo with bgproc, drives the admin with agent-browser using the dev-bypass session, and captures the reproduction as screenshots plus a written transcript.

Reproduce a bug in the public-facing rendered site (not the admin). Boots a demo with bgproc, drives the public routes with agent-browser, and captures the reproduction as screenshots plus a written transcript.

Reproduce an EmDash bug that lives below the browser layer -- REST handlers, CLI, MCP, migrations, schema registry, or build tooling. No agent-browser. Prefer a failing vitest test in the affected package.

Use the EmDash CLI to manage content, schema, media, and more. Use this skill when you need to interact with a running EmDash instance from the command line — creating content, managing collections, uploading media, generating types, or scripting CMS operations.

Port a WordPress plugin to EmDash CMS. Use this skill when asked to migrate, convert, or port a WordPress plugin, theme functionality, or custom post type to EmDash. Provides concept mapping and implementation patterns.

Port WordPress themes to EmDash CMS. Use when asked to convert, migrate, or port a WordPress theme to EmDash, or when creating an EmDash site that should match an existing WordPress site's design. Handles design extraction, template conversion, and EmDash-specific features like menus, taxonomies, and widgets.

Adversarial code review that assumes bugs exist and hunts for them. Use when asked to review code, find bugs, audit for correctness, stress-test a PR, or when someone says "tear this apart" or "what's wrong with this". Give no benefit of the doubt — every line is guilty until proven innocent.

Browser automation for testing and verification. Use when you need to interact with web UIs, verify visual changes, fill forms, or capture screenshots.
