Jira Query Language (JQL) — Expert Reference

JQL is Atlassian's structured query language for searching Jira issues (now called "work items"). Every clause is Field + Operator + Value, chained with keywords.

Use this skill when:

• The user asks for help writing or debugging a JQL query
• They need to find issues across projects, sprints, versions, components
• They want to use history operators (WAS, CHANGED) for trend/sprint analysis
• Performance optimization or saved filter design is needed
• They're building automation rules, REST API calls, or dashboard gadgets with JQL
