Use When

• Set up and configure Jenkins on Debian/Ubuntu — installation, Declarative Jenkinsfile patterns, master/agent distributed builds, Docker build agents, plugin recommendations, credentials management, and RBAC. Synthesised from CI/CD Pipeline Using Jenkins Unleashed (Dingare), CI/CD Pipeline with Docker and Jenkins (Rawat), and DevOps Design Patterns (Chintale). Use when installing Jenkins, writing Jenkinsfiles, or architecting a self-hosted CI/CD system on Debian/Ubuntu servers.
• The task needs reusable judgment, domain constraints, or a proven workflow rather than ad hoc advice.

Do Not Use When

• The task is unrelated to cicd-jenkins-debian or would be better handled by a more specific companion skill.
• The request only needs a trivial answer and none of this skill's constraints or references materially help.

Required Inputs

• Gather relevant project context, constraints, and the concrete problem to solve.
• Confirm the desired deliverable: design, code, review, migration plan, audit, or documentation.
