Upstream overview and integrations

Before you use it

• An Agent that can load Skill Markdown and access your project. File edits, shell commands, builds and checks depend on the selected workflow and its environment.
• Use your project's own runtimes, dependencies and verification commands. The Skill files provide instructions and do not install those project tools.
• Install the complete pack through a documented repository integration when shared references are needed. A per-skill skills CLI install copies only skills/<name>/ and can omit the repository-level references/ checklists; keep the needed shared files with the workflow.
