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. The package's agent instructions become available to Claude Code or Codex sessions and may influence subsequent agent behavior. - **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:** 5.78.3 - **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 automatically adds or refreshes its skill in existing Claude Code and Codex agent registries. This modifies AI-agent control surfaces without a separate setup command or consent step. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 97.0% - **Started:** 2026-09-19T14:51:39.084Z - **Finished:** 2026-09-19T14:52:37.419Z - **Download time:** 501 ms - **Static scan time:** 6071 ms - **AI review time:** 51763 ms - **Total time:** 58335 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:** Installing the package automatically adds or refreshes its skill in existing Claude Code and Codex agent registries. This modifies AI-agent control surfaces without a separate setup command or consent step. - **Trigger:** npm postinstall after package installation when ~/.claude or ~/.codex exists. - **Impact:** The package's agent instructions become available to Claude Code or Codex sessions and may influence subsequent agent behavior. - **Evidence paths:** package.json, scripts/postinstall.js, skill/greprag/SKILL.md - **Review source:** ai\_review - **Reviewed:** 2026-09-19T14:52:37.419Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Recursive installation of bundled agent skills into existing global skill directories. - **Attack narrative:** The package declares an automatic postinstall hook. When a user already has Claude Code or Codex installed, that hook creates or overwrites the package's core skill under the corresponding global agent skills directory. The copied SKILL.md provides instructions for future agent sessions. This is an unconsented install-time mutation of foreign AI-agent control surfaces. - **Rationale:** The automatic lifecycle hook writes package-controlled instructions into existing global Claude Code and Codex skill registries. That concrete install-time control-surface mutation meets the blocking policy even though the inspected installer does not make network requests. - **Files touched:** ~/.claude/skills/greprag, ~/.codex/skills/greprag ### Review decision - **Verdict:** Malicious - **Confidence:** 97.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The manifest runs a postinstall script automatically., The postinstall script targets existing Claude Code and Codex home directories and their skills directories., The postinstall script recursively copies bundled skill content into those agent-controlled directories, including a core skill even when it did not exist before., The bundled skill contains agent instructions that become available through the installed skill registry. - **Evidence against:** The postinstall script only acts when the relevant agent home directory already exists., No network request or credential collection occurs in the inspected postinstall path. ## Affected versions and remediation This report applies to greprag@5.78.3. - Avoid installing greprag@5.78.3. 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.
