- context-engineeringmvschwarz/openrigUse when designing, reviewing, or debugging how an agent's context window gets filled, pruned, or shared — choosing what loads at boot versus on demand, sizing an install or an always-loaded file, fixing an agent that drifts, repeats itself, or forgets constraints mid-task, planning compaction or summarization, deciding single-agent versus subagents, engineering handoffs between agents, or picking a tool loadout. NOT for rewording a prompt's tone, choosing which model to pin, or debugging business logic — those are adjacent moments this skill does not serve.

From the author
Prioritize and rank the Elastic Security alert queue by weighted risk — base risk score, MITRE tactic boost, entity risk, and asset criticality — then cluster alerts into entity groups. Use when an analyst asks what to focus on, which alerts are most urgent, or wants a ranked starting point across the queue before deeper investigation begins.
