It also changes an existing Claude Desktop configuration and project skill lock files. - **Trigger:** Installing the package through npm runs postinstall. - **Impact:** A package install can cause AI clients in the consumer project or user profile to launch pgautopilot without an explicit setup command. - **Evidence paths:** package.json, scripts/postinstall.mjs, scripts/merge-skills-lock.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-13T22:06:43.397Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic AI-agent configuration and skill-lock mutation. - **Attack narrative:** On npm installation, package.json invokes scripts/postinstall.mjs. That script adds pgautopilot MCP launch entries for many AI tools, writes a Codex configuration, and changes an existing Claude Desktop configuration in the user profile. It then executes merge-skills-lock.mjs against the consumer project, which modifies an existing skill lock or creates one. These changes occur without an explicit user setup command and create persistent AI-agent launch and capability configuration. - **Rationale:** This is unconsented postinstall mutation of foreign AI-agent control surfaces and project skill metadata. The automatic lifecycle behavior is sufficient for a publish block even though no data exfiltration was found in the inspected code. - **Files touched:** config/cursor/mcp.json, config/vscode/mcp.json, config/codex/config.toml, config/claude/mcp.json, skills-lock.json, .skill-lock.json, skills.lock, skills-lock.yaml ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The package runs a postinstall script automatically during npm installation., The postinstall script registers pgautopilot as an MCP command for many AI editor clients., It rewrites or creates project configuration files and also modifies an existing Claude Desktop configuration in the user's home directory., It automatically launches a second script that adds package skills to existing or new project skill lock files. - **Evidence against:** No runtime self-dependency is declared., The inspected install code does not send harvested data to a remote endpoint. ## Affected versions and remediation This report applies to pgautopilot@2.4.0. - Avoid installing pgautopilot@2.4.0. 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.
