Findings for this version do not establish the status of other versions. AI assessment: manual review; recommendation: manual review. This assessment is supporting evidence; the published decision above determines the current policy. Static inspection found a potentially consequential agent skill installation capability, but could not establish its reachability or consent boundary in the obfuscated bundle. The manifest shows no npm install-time hook, so the available evidence does not establish malicious behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Manual Review - **Recorded analysis confidence:** 58.0% - **Started:** 2026-10-15T11:53:42.059Z - **Finished:** 2026-10-15T11:55:40.287Z - **Download time:** 1537 ms - **Static scan time:** 2009 ms - **AI review time:** 114681 ms - **Total time:** 118228 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 MCP bundle contains a skill download and installation capability, but inspection did not establish whether its helpers are reachable or consent-gated. - **Trigger:** Unresolved; no activating caller was confirmed by static inspection. - **Impact:** If reachable without an effective consent boundary, it could add or update agent skill files; the resulting behavior is unresolved. - **Evidence paths:** dist/mcp.cjs - **Review source:** ai\_review - **Reviewed:** 2026-10-15T11:55:40.287Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The helper downloads skill content and writes files into selected agent skill directories. - **Rationale:** Static inspection found a potentially consequential agent skill installation capability, but could not establish its reachability or consent boundary in the obfuscated bundle. The manifest shows no npm install-time hook, so the available evidence does not establish malicious behavior. - **Files touched:** dist/mcp.cjs ### Review decision - **Verdict:** Manual Review - **Confidence:** 58.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** Medium - **AI review observations:** The manifest has a prepublish-only build hook, with no preinstall, install, or postinstall hook., The MCP bundle defines a helper that downloads skill files using a bearer token and a service base passed to the helper., The bundle contains a helper that writes downloaded files into agent skill directories, including workspace and home-directory scopes., The entrypoint and MCP bundle are heavily obfuscated, and static inspection did not resolve the skill helpers’ callers or consent boundary. - **Evidence against:** The installer checks file paths and skips paths that escape the selected skill directory., The manifest points the package entrypoint and command aliases to dist/index.cjs; the skill helpers are in dist/mcp.cjs. ## Affected versions and remediation This report applies to @whalent/agent@0.3.510. - Review the evidence and your use of @whalent/agent@0.3.510 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
