Intelligently organizes your files and folders across your computer by understanding context, finding duplicates, suggesting better structures, and automating cleanup tasks. Reduces cognitive load and keeps your digital workspace tidy without manual effort.

Generate concrete counterexamples when formal verification, assertions, or specifications fail. Use this skill when debugging failed proofs, understanding why verification fails, creating minimal reproducing examples, analyzing assertion violations, investigating invariant breaks, or diagnosing specification mismatches. Produces concrete input values, execution traces, and state information that demonstrate the failure.

CLI application patterns for Python. Triggers on: cli, command line, typer, click, argparse, terminal, rich, console, terminal ui.

Toolkit for interacting with and testing local web applications using Playwright. Supports verifying frontend functionality, debugging UI behavior, capturing browser screenshots, and viewing browser logs.

ClickHouse数据库模式、查询优化、分析以及高性能分析工作负载的数据工程最佳实践。

Creates specs before coding. Use when starting a new project, feature, or significant change and no specification exists yet. Use when drafting a PRD or requirements document with objectives and scope, or when requirements are unclear, ambiguous, or only exist as a vague idea. Use when a single requirement spans several independently testable capabilities and needs decomposing into a capability map of modules before specifying.

Cache original web pages locally with `web cache serve`, a caching reverse proxy for iterative migration work. Navigate pages through it (manually or with a browser) and every resource is saved to disk; restart it offline to replay the full site with no network, bot detection or rate limits. Triggers on: page cache, cache page, cache site, cache website, offline cache, warm cache, cache proxy, page-cache, site mirror, cache for migration.

Discover and collect all URLs of a website with the web CLI: parses robots.txt and sitemaps (XML, sitemap indexes, gzip) or follows links, with include/exclude glob patterns, a URL limit and language detection from the URL path. Triggers on: site urls, list pages, discover urls, site inventory, url collection, find all pages, site-scan, website urls, enumerate pages, map site, how many pages.

Read-only automated QA sweep of a deployed stardust site on AEM Edge Delivery Services — validates routing, content fidelity vs the source capture, template conformance, rendered integrity (geometry, JS errors, broken images), visual regression vs baselines, metadata/SEO/JSON-LD, link integrity, accessibility (axe), and performance budgets, then emits a findings report with an allowlist for documented non-defects. Finds issues; never fixes them. Use when the user asks to "QA the site", "validate the migration", "check the live site for issues", "run a QA sweep/regression check", or invokes `$stardust qa` (`/stardust:qa` in Claude Code) <live-url>.

Use when publishing, unpublishing, replicating, or activating/deactivating content in AEM 6.5 LTS. Covers Quick Publish, Manage Publication, tree activation, bulk content activation, package replication, workflow-based approval, scheduled activation/deactivation (on/off time), dispatcher flush, and the programmatic Replication Java API for AEM publish instances.
