Changes the behavior of a third-party agent extension in the consumer dependency tree. - **Verdict:** AI-agent control-surface policy finding - **Product-default install policy:** Warn by default; block when configured - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 0.9.19 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This finding concerns changes to an AI agent's instructions or configuration without explicit user action. It does not by itself establish malware intent. The CLI warns by default and blocks when configured for this policy. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. LPM flags this version as an AI-agent control-surface risk. Installing the package automatically rewrites source code in the separately installed pi-subagents agent extension. The change is guarded and narrow, but it is an unconsented postinstall mutation of a foreign AI-agent component. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-09-10T03:39:11.796Z - **Finished:** 2026-09-10T03:40:38.398Z - **Download time:** 767 ms - **Static scan time:** 4019 ms - **AI review time:** 81815 ms - **Total time:** 86602 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** Installing the package automatically rewrites source code in the separately installed pi-subagents agent extension. The change is guarded and narrow, but it is an unconsented postinstall mutation of a foreign AI-agent component. - **Trigger:** npm installation, which runs postinstall automatically. - **Impact:** Changes the behavior of a third-party agent extension in the consumer dependency tree. - **Evidence paths:** package.json, scripts/patch-pi-subagents-stale-ctx.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-10T03:40:38.398Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall source patching of pi-subagents. - **Attack narrative:** The package's postinstall hook resolves pi-subagents, finds its extension index source, and overwrites a specific error matcher. Although the patch is limited and does not exfiltrate data or execute a shell command, it silently changes a foreign AI-agent extension during installation. This meets the install control-surface policy for a blocking lifecycle mutation. - **Rationale:** The automatic lifecycle hook modifies a foreign agent-extension source file. Its narrow scope lowers uncertainty about behavior but does not establish user consent for the install-time mutation. - **Files touched:** scripts/patch-pi-subagents-stale-ctx.mjs, node\_modules/pi-subagents/src/extension/index.ts ### Review decision - **Verdict:** Malicious - **Confidence:** 91.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** Installation automatically runs a script that modifies an installed agent-extension dependency., The script locates pi-subagents and targets its extension source file., It replaces the dependency's stale-context error matcher and writes the result back to disk. - **Evidence against:** The modification is narrowly guarded: it exits when the dependency, target, or expected source text is absent., The install script contains no network request, shell command, or credential collection., package.json has no runtime dependency on its own package name. ## Affected versions and remediation This report applies to @twofive/snail-pi-web@0.9.19. - Avoid installing @twofive/snail-pi-web@0.9.19. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
