Subsequent agent sessions receive package-supplied tool-selection directives through a shared control surface. - **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:** 3.0.1 - **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. Automatic installation modifies Pi's shared system instructions. The fallback reaches an existing user-wide agent directory outside the package's own installation scope. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 96.0% - **Started:** 2026-10-05T04:27:16.921Z - **Finished:** 2026-10-05T04:28:29.851Z - **Download time:** 760 ms - **Static scan time:** 335 ms - **AI review time:** 71834 ms - **Total time:** 72930 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:** Automatic installation modifies Pi's shared system instructions. The fallback reaches an existing user-wide agent directory outside the package's own installation scope. - **Trigger:** npm postinstall when a Pi scope or existing fallback agent directory is found. - **Impact:** Subsequent agent sessions receive package-supplied tool-selection directives through a shared control surface. - **Evidence paths:** package.json, scripts/append-system.mjs, instructions.md - **Review source:** ai\_review - **Reviewed:** 2026-10-05T04:28:29.851Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The lifecycle helper reads package instructions and inserts them into APPEND\_SYSTEM.md without a separate opt-in check. - **Attack narrative:** Installing the package automatically runs its instruction helper. Even outside a managed extension installation, the helper can locate the existing user-wide Pi directory and append package instructions to its shared system prompt. Package markers limit replacement to its own block, but do not prevent the unconsented modification of the broader agent control surface. - **Rationale:** The user-wide fallback makes this an automatic mutation of a broad AI-agent control surface, rather than setup confined to package-owned extension state. This meets the supplied blocking rule despite the tool-related content and bounded block replacement. - **Files touched:** APPEND\_SYSTEM.md ### Review decision - **Verdict:** Malicious - **Confidence:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** package.json automatically runs the instruction installer during postinstall., The installer falls back to an existing user-wide Pi agent directory without a separate consent gate., The installer writes a package-marked block into shared APPEND\_SYSTEM.md., instructions.md supplies directives that change the agent's tool-selection behavior. - **Evidence against:** Writes use package-specific block markers and preserve surrounding instructions., The inserted instructions concern the package's web retrieval tools. ## Affected versions and remediation This report applies to @vanillagreen/pi-web-tools@3.0.1. - Avoid installing @vanillagreen/pi-web-tools@3.0.1. 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.
