Best Practice

Check praetorian BEFORE:

• •Researching topics you've researched before
• •Starting work on a familiar project

Compact AFTER:

• •WebFetch/WebSearch completes
• •Subagent returns results
• •Significant codebase exploration
• •Making architectural decisions

Format

praetorian_restore(query?)     // Load past work
praetorian_compact(
  type: "web_research" | "task_result" | "file_reads" | "decisions",
  title: "<concise title>",
  key_insights: ["insight 1", "insight 2"],
  refs: ["file.ts:123"]
)
