The original title is 10 words: "Local-First Is a Data Boundary, Not a Safety Guarantee"

Short summary

Local execution of AI coding tools reduces data exposure but does not constitute a complete safety model. The author argues that security reviews should focus on concrete boundaries—readable files, writable files, permitted commands, and allowed external systems—rather than vague trust assessments. Monitoring surfaces should remain read-only, with consequential actions routed through explicit reviewable workflows.

• •Local-first is a deployment property, not a safety guarantee—define readable files, writable files, permitted commands, and allowed external systems before each session
• •Keep secrets out of prompts and transcripts; use scoped stores with separated read/write authority
• •Monitoring should be read-only; never let a status dashboard become a remote-control surface
