A dependency installation can replace or add consumer project agent instructions, skills, commands, rules, and entry bridges without explicit consent. - **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:** 3.8.1 - **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. Installing the package triggers code that modifies consumer AI-agent control directories. It defaults to Claude Code in CI or on closed input and can overwrite agent behavior files. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-10T02:58:20.656Z - **Finished:** 2026-09-10T02:59:22.705Z - **Download time:** 511 ms - **Static scan time:** 66 ms - **AI review time:** 61470 ms - **Total time:** 62049 ms The recorded confidence comes from the underlying analysis.

It defaults to Claude Code in CI or on closed input and can overwrite agent behavior files. - **Trigger:** npm postinstall - **Impact:** A dependency installation can replace or add consumer project agent instructions, skills, commands, rules, and entry bridges without explicit consent. - **Evidence paths:** package.json, .catalyst/bin/install.js - **Review source:** ai\_review - **Reviewed:** 2026-09-10T02:59:22.705Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** automatic broad AI-agent configuration overwrite - **Attack narrative:** The npm postinstall invokes the installer automatically. When no interactive selection is available, including CI, it chooses Claude Code, then recursively copies package-controlled agents, commands, skills, and rules into the consumer project and overwrites existing files. It also writes AGENTS.md and may add a CLAUDE.md bridge that causes those instructions to load. This is unconsented mutation of a foreign AI-agent control surface during dependency installation. - **Rationale:** The package has a concrete automatic postinstall chain that defaults to and overwrites consumer AI-agent control files. This meets the install-control-surface blocking policy. - **Files touched:** .claude/agents, .claude/commands, .claude/skills, .claude/rules, .pi/agents, .pi/prompts, .pi/skills, .pi/rules, .codex/agents, .codex/prompts, .codex/skills, .codex/rules, AGENTS.md, CLAUDE.md, .gitignore, .catalyst/secrets.local.yaml ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** Postinstall automatically runs the installer., In CI, installer defaults to Claude Code without a user choice., Installer recursively overwrites agents, commands, skills, and rules in consumer AI-agent directories., Installer adds an AGENTS bridge and overwrites AGENTS.md in the consumer project., Installer also changes the consumer .gitignore and creates a secrets file. - **Evidence against:** No runtime dependency on another catalyst-os release was found., The ElevenLabs request is in a separately installed local voice daemon and requires a configured key. ## Affected versions and remediation This report applies to catalyst-os@3.8.1. - Avoid installing catalyst-os@3.8.1. 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.
