Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Soft block: AI-agent control surface** — Warn by default; block when configured. Persistent modification of global agent instructions affecting subsequent Claude sessions. - **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:** 3.55.0 - **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. The npm postinstall lifecycle adds instructions to Claude's global control file without requiring consent. This changes agent behavior across projects. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-30T04:25:16.946Z - **Finished:** 2026-09-30T04:27:17.009Z - **Download time:** 513 ms - **Static scan time:** 1809 ms - **AI review time:** 117740 ms - **Total time:** 120063 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:** The npm postinstall lifecycle adds instructions to Claude's global control file without requiring consent. This changes agent behavior across projects. - **Trigger:** Installing the package with npm lifecycle scripts enabled, when the harness block is absent and CTS\_NO\_HARNESS is not 1. - **Impact:** Persistent modification of global agent instructions affecting subsequent Claude sessions. - **Evidence paths:** package.json, bin/cli.js, src/commands/install.js, src/harness.js - **Review source:** ai\_review - **Reviewed:** 2026-09-30T04:27:17.009Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall invokes the install command, which defaults to noninteractive setup and calls the global harness writer. - **Attack narrative:** Installing the package automatically invokes its setup command. Confirmation is conditional on an optional manual flag absent from postinstall. The default path initializes a global harness and appends generated instructions to ~/.claude/CLAUDE.md. Preserving existing content and providing an environment opt-out do not establish consent for modifying this broad agent control surface. - **Rationale:** Inspected source establishes unconsented postinstall mutation of a global AI-agent instruction file. This meets the supplied blocking policy independently of citation coverage or any unproven exfiltration. - **Files touched:** ~/.claude/CLAUDE.md ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** package.json automatically runs the install command during postinstall., bin/cli.js dispatches that command to src/commands/install.js., Setup prompts require the manual flag; the automatic lifecycle does not supply it., Setup proceeds by default and initializes the global harness., src/harness.js resolves the global destination to ~/.claude/CLAUDE.md and appends the generated instruction block. - **Evidence against:** The installer preserves existing instructions and creates a backup., CTS\_NO\_HARNESS=1 can disable harness setup, but the default lifecycle does not require consent. ## Affected versions and remediation This report applies to sprag-cli@3.55.0. - Avoid installing sprag-cli@3.55.0. 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.
