The skill's footprint is coherent with its stated purpose: it reads local Copilot session data, generates a Mermaid diagram, outputs a markdown file, and can delete session artifacts. Access is limited to local files; no credentials or external network activity are described. The deletion capability introduces potential data loss risk that should be mitigated with user confirmation and dry-run options. Overall risk is low to moderate (benign) given the described scope and data handling.
