# Skill: Ralph — Two-Pass Issue Scanning **Confidence:** high **Domain:** work-monitoring **Last validated:** 2026-03-24 ## Context Cuts GitHub API calls from N+1 to ~7 per round (~72% reduction) by separating list scanning from full hydration. Addresses the scanning inefficiency described in issue #596. ## Pattern ### Pass 1 — Lightweight Scan ``` gh issue list --state open --json number,title,labels,assignees --limit 100 ``` **Skip hydration if ANY of these match:** | Condition | Skip reason | |-----------|-------------| | `assignees` non-empty AND no `status:needs-review` | Already owned | | Labels contain `status:blocked` or `status:waiting-external` | Externally gated | | Labels contain `status:done` or `status:postponed` | Closed loop | | Title matches stale/noisy pattern (`[chore]`, `[auto]`) | Low-signal | ### Pass 2 — Selective Hydration For each issue surviving Pass 1: ``` gh issue view <number> --json number,title,body,labels,assignees,comments,state ``` Then apply normal Ralph triage logic. Rule of thumb: hydrate ≤ 30% of scanned list. If more than 30% survive Pass 1, tighten filter rules.
