Install-time script modifies the user's Pi agent environment by installing/registering extensions and copying bundled agent definitions. This is an agent lifecycle/control-surface change, but source inspection did not show exfiltration, stealth persistence, destructive behavior, or remote payload execution beyond package-manager installs. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 86.0% - **Started:** 2026-07-10T08:32:32.106Z - **Finished:** 2026-07-10T08:33:00.470Z - **Download time:** 764 ms - **Static scan time:** 12 ms - **AI review time:** 27587 ms - **Total time:** 28364 ms ## Security analysis ### Published attack-surface review - **Summary:** Install-time script modifies the user's Pi agent environment by installing/registering extensions and copying bundled agent definitions. This is an agent lifecycle/control-surface change, but source inspection did not show exfiltration, stealth persistence, destructive behavior, or remote payload execution beyond package-manager installs. - **Trigger:** npm install of @xaccefy/pi-xpi@0.2.4 - **Impact:** Pi agent settings and agent markdown files may be changed at install time - **Evidence paths:** package.json, install.sh, agents/harness.md, agents/exploit-dev.md, agents/auditor.md, agents/patch-writer.md, prompts/engage.md, prompts/pipeline.md - **Review source:** ai\_review - **Reviewed:** 2026-07-10T08:33:00.470Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall Pi agent extension setup - **Rationale:** Because the package performs install-time mutation of a Pi agent control surface, it should not be marked clean; however the behavior is first-party/package-aligned extension setup without a concrete malicious chain. Treat as a warning lifecycle risk rather than a publish block. - **Files touched:** ~/.pi/agent/settings.json, ~/.pi/agent/agents/\*.md - **Network endpoints:** https://github.com/x4cc3/pi-xpi, https://registry.npmjs.org/, https://preview.is ### Review decision - **Verdict:** Suspicious - **Confidence:** 86.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for:** \`package.json\` runs \`bash install.sh\` in \`postinstall\`., \`install.sh\` calls \`pi install\`/\`npm install --no-save\` for other agent extensions during install., On \`pi install\` failure, \`install.sh\` appends package names to \`~/.pi/agent/settings.json\`., \`install.sh\` copies bundled agent markdown into \`~/.pi/agent/agents/\` during install. - **Evidence against:** No package JS entrypoint, main, bin, or runtime code is shipped., No credential harvesting or exfiltration logic found in inspected files., Only network-relevant strings are npm package installs and informational URLs in manifest/README prompt text., The settings mutation is limited to Pi agent extension packages and bundled Pi agent files. ## Public findings ### 1.
