Claude Skill
An extensibility mechanism introduced by Anthropic for Claude. It is essentially a folder containing instruction files (SKILL.md), resource templates and optional scripts that tells Claude which workflow to follow, which tools to invoke and what output format to produce for a given task scenario, and can be uploaded or installed in the Claude app or Claude Code.

Timeline (last 90 days)
Claude Skill's design philosophy is similar to plugins, but places more emphasis on describing trigger conditions in natural language.
The focus of competition in the Skill ecosystem is shifting from whether they exist to whether they can be found, and indexing, retrieval, and recommendation are becoming new value links.
The utility of a meta-Skill is positively correlated with ecosystem scale: once the number of Skills crosses a certain threshold, automated discovery and routing become essential.
The video mentions that just finding the correct Skill takes several hours.
Developer dooa-ansari shared a project on Dev.to that feeds an ordinary resume into a custom Claude Skill, producing an animated, interactive single-page personal website
The project uses Claude Skill as a process orchestrator and information extractor, while leaving the hard parts such as animation, layout and interaction to templates and scripts
The technical foundation of this testing Agent system consists of three components: the official Atlassian MCP, Playwright MCP, and a Claude Skill.
The skill file requires that the test plan be confirmed with the user before generating tests, and execution only continues after confirmation is received.
The skill file assigns the Agent the role of a senior QA engineer and test automation architect, and stipulates a four-step workflow of read, plan, generate, execute, and report.
Claude's skill files must be in .md format, and if packaged as a zip, must include a skill folder.

The Skill Set mechanism allows Claude to load the full content of a Skill into the context window only when it determines the Skill needs to be used, enabling on-demand loading.
