Agent Skills: lisa-ticket-triage

Analytical triage gate for tickets in the configured destination tracker (JIRA, GitHub Issues, or Linear). Detects requirement ambiguities, identifies edge cases from codebase analysis, plans verification methodology, and — via lisa-rework-triage in Phase 2.5 — detects rework bounced back from QA/staging and classifies why the previous agent attempt failed. Posts findings to the ticket and produces a verdict (DUPLICATE_ALREADY_FIXED/BLOCKED/PASSED_WITH_FINDINGS/PASSED) that gates whether implementation can proceed. Vendor-neutral: the caller (jira-agent or github-agent) is responsible for fetching the ticket via lisa-tracker-read, running the pre-flight gate via lisa-tracker-verify, and posting findings via the matching vendor comment tool.
