Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. LPM treats this as warn-only first-party agent extension lifecycle risk. npm installation mutates a dependency's Pi subagent extension source. The confirmed change is limited to broadening a stale-context error matcher; no exfiltration or remote payload path was found. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 88.0% - **Started:** 2026-08-14T10:20:27.535Z - **Finished:** 2026-08-14T10:21:18.615Z - **Download time:** 1511 ms - **Static scan time:** 4201 ms - **AI review time:** 45367 ms - **Total time:** 51080 ms The recorded confidence comes from the underlying analysis.

The confirmed change is limited to broadening a stale-context error matcher; no exfiltration or remote payload path was found. - **Trigger:** npm install / postinstall - **Impact:** Changes agent-extension lifecycle error handling in node\_modules. - **Evidence paths:** package.json, scripts/patch-pi-subagents-stale-ctx.mjs, bin/pi-web.js - **Review source:** ai\_review - **Reviewed:** 2026-08-14T10:21:18.615Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** guarded overwrite of pi-subagents extension source - **Rationale:** The package is not shown to be malicious, but its postinstall script modifies a third-party agent extension at install time. This creates a concrete lifecycle integrity risk that warrants a warning rather than a block. - **Files touched:** scripts/patch-pi-subagents-stale-ctx.mjs, node\_modules/pi-subagents/src/extension/index.ts ### Review decision - **Verdict:** Suspicious - **Confidence:** 88.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** Install lifecycle automatically runs a patch script., The script locates and overwrites pi-subagents' extension source., The overwrite changes stale-extension error handling in an agent dependency. - **Evidence against:** Patch is narrowly guarded by an exact expected source matcher., No network, credential collection, or exfiltration appears in the lifecycle script., Flagged favicon payload is a 512×512 PNG image, not executable data. ## Affected versions and remediation This report applies to @twofive/snail-pi-web@0.9.12. - Review the evidence and your use of @twofive/snail-pi-web@0.9.12 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
