The video frames these as replacements for hand-written Claude.md instructions or custom skills developers previously maintained themselves, and notes the generator is most useful when starting an app is non-trivial (not needed for simple cases like npm start). ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What does the /run skill do in Claude Code? The /run skill is a built-in Claude Code capability that starts an application, whether it's a CLI, TUI, or web app, and then verifies it is actually running by finding the entry point and interacting with it. It can handle tricky cases, such as apps that launch hidden in the system tray, by triggering the right keyboard shortcuts to open and test them. _Developers automating app startup checks can follow ongoing Claude Code skill coverage on daily.dev._ ### How does the /verify skill in Claude Code check that a code change works? The /verify skill reads the git diff to understand what was just changed, then runs and exercises the application to confirm the change behaves as expected, including taking screenshots to check visual results. It is meant as a quick first-pass sanity check before manual testing or running automated unit and integration tests, not a replacement for them. _Teams deciding how much to trust AI-driven checks before shipping can track these workflow patterns on daily.dev._ ### What is the run skill generator in Claude Code used for? The run skill generator inspects a project to find or create a reusable skill for starting the application, producing a skill.md file and an accompanying script that describe how to build, run, and check the app across different scenarios, such as onboarding or smoke tests. It's most useful when starting an app is complex; for simple cases like npm start, it isn't necessary. _Developers wanting less boilerplate in their claude.md files can follow Claude Code tooling updates on daily.dev._ --- Tags: [#testing](https://daily.dev/tags/testing), [#ai-agents](https://daily.dev/tags/ai-agents), [#claude-code](https://daily.dev/tags/claude-code) [View this post on daily.dev](https://daily.dev/posts/3-claude-code-skills-i-wish-i-d-found-sooner-tsuna5kbp) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"3 Claude Code Skills I Wish I'd Found Sooner","url":"https://daily.dev/posts/3-claude-code-skills-i-wish-i-d-found-sooner-tsuna5kbp","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/3-claude-code-skills-i-wish-i-d-found-sooner-tsuna5kbp"},"datePublished":"2026-09-01T11:31:29.388Z","dateModified":"2026-09-01T11:31:50.257Z","description":"A walkthrough of three built-in Claude Code skills that automate common developer workflows: /run starts an application (CLI, TUI, or web) and verifies it's...","image":"https://i.ytimg.com/vi/zHADkOEhdtc/sddefault.jpg","thumbnailUrl":"https://i.ytimg.com/vi/zHADkOEhdtc/sddefault.jpg","isAccessibleForFree":true,"articleSection":"We Are .NET","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"We Are .NET","logo":"https://media.daily.dev/image/upload/s--BsnVOa3i--/f_auto/v1718347410/logos/wearedotnet","url":"https://daily.dev/sources/wearedotnet"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/3-claude-code-skills-i-wish-i-d-found-sooner-tsuna5kbp","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":2},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"testing,ai-agents,claude-code","timeRequired":"PT8M","video":{"@type":"VideoObject","name":"3 Claude Code Skills I Wish I'd Found Sooner","description":"A walkthrough of three built-in Claude Code skills that automate common developer workflows: /run starts an application (CLI, TUI, or web) and verifies it's...","thumbnailUrl":"https://i.ytimg.com/vi/zHADkOEhdtc/sddefault.jpg","uploadDate":"2026-09-01T11:31:29.388Z","duration":"PT8M","url":"https://api.daily.dev/r/tsunA5KbP","embedUrl":"https://www.youtube.com/embed/zHADkOEhdtc"}} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"We Are .NET","item":"https://daily.dev/sources/wearedotnet"},{"@type":"ListItem","position":3,"name":"3 Claude Code Skills I Wish I'd Found Sooner"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/3-claude-code-skills-i-wish-i-d-found-sooner-tsuna5kbp#faq","mainEntity":[{"@type":"Question","name":"What does the /run skill do in Claude Code?","acceptedAnswer":{"@type":"Answer","text":"The /run skill is a built-in Claude Code capability that starts an application, whether it's a CLI, TUI, or web app, and then verifies it is actually running by finding the entry point and interacting with it.
