Matching agents acquire the plugin's tools and automatic conversation compaction behavior through an installation-time configuration change. - **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:** 0.3.1 - **Selected version is latest:** Yes - **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. Installation automatically changes foreign dsh agent preset configurations to load smart-compaction. The changes extend across matching local presets without explicit authorization. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-10-01T15:27:26.217Z - **Finished:** 2026-10-01T15:28:38.357Z - **Download time:** 757 ms - **Static scan time:** 29 ms - **AI review time:** 71353 ms - **Total time:** 72140 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:** Installation automatically changes foreign dsh agent preset configurations to load smart-compaction. The changes extend across matching local presets without explicit authorization. - **Trigger:** npm postinstall runs scripts/mount-into-presets.mjs. - **Impact:** Matching agents acquire the plugin's tools and automatic conversation compaction behavior through an installation-time configuration change. - **Evidence paths:** package.json, scripts/mount-into-presets.mjs - **Review source:** ai\_review - **Reviewed:** 2026-10-01T15:28:38.357Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The script enumerates local preset directories, inserts its plugin registration beside an existing compaction backend, and writes the modified configuration. - **Attack narrative:** Installing the package runs a script that locates the user's dsh presets and adds smart-compaction registrations to matching agent configurations. Existing-backend and duplicate checks restrict which files change, but do not establish consent to modify these foreign agent control surfaces. The inserted plugin can subsequently register tools and automatically compact conversation history. - **Rationale:** The inspected postinstall performs unconsented mutation of foreign AI-agent preset configurations, meeting the supplied blocking rule. Its functional purpose and matching guards do not remove that concrete lifecycle behavior. - **Files touched:** .dsh, .agent-presets, agent.cordis.yml ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** package.json automatically runs the preset mutation script after installation., The script targets DSH\_HOME or the user's .dsh directory and scans local .agent-presets directories., It inserts smart-compaction plugin registrations into matching presets and writes agent.cordis.yml without a consent gate. - **Evidence against:** Mutation skips missing presets, presets without the compaction backend, and already registered plugins., Runtime code provides context usage and conversation compaction; no credential harvesting or direct network export was identified. ## Affected versions and remediation This report applies to smart-compaction@0.3.1. - Avoid installing smart-compaction@0.3.1. 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.
