Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. The bundle can rewrite foreign agent MCP configs and skill directories, but only through an explicit daemon tool action, and package.json has no install hook. That is a guarded agent-control capability, so it warrants a warning rather than a publish block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 74.0% - **Started:** 2026-09-26T21:12:54.260Z - **Finished:** 2026-09-26T21:15:07.119Z - **Download time:** 763 ms - **Static scan time:** 2212 ms - **AI review time:** 129883 ms - **Total time:** 132859 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 daemon tool can register an MCP server into another agent's config and install skill files under .claude, .cursor, or .agents. That happens only after the running daemon receives the matching tool action, not during npm install. - **Trigger:** An explicit daemon tool call with action register, or the skill install action, while dist/mcp.cjs is running. - **Impact:** A caller of the daemon can add or replace MCP server entries and skill files for other local AI agents. There is no install-time or silent startup mutation. - **Evidence paths:** dist/mcp.cjs, package.json - **Review source:** ai\_review - **Reviewed:** 2026-09-26T21:15:07.119Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** injectMcpServer selects Claude, OpenCode, Kimi, or Codex and writes the supplied command into that product's MCP config. installSkill resolves a platform skill directory and writes the provided files. - **Rationale:** The bundle can rewrite foreign agent MCP configs and skill directories, but only through an explicit daemon tool action, and package.json has no install hook. That is a guarded agent-control capability, so it warrants a warning rather than a publish block. - **Files touched:** .claude.json, .claude, .cursor, .agents, mcp.json, config.toml ### Review decision - **Verdict:** Suspicious - **Confidence:** 74.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** A daemon tool action named register calls injectMcpServer with the caller-supplied server name, command, args, and env., injectMcpServer writes that server into Claude, OpenCode, Kimi, or Codex config, including ~/.claude.json via writeClaudeConfig., installSkill creates a directory from platformDir (.claude, .cursor, or .agents) under the home directory or workspace and writes skill files there., package.json exposes the whalent-core CLI and has no install lifecycle scripts, so these writes run only when the daemon tool is invoked. - **Evidence against:** Published package.json has no preinstall, install, or postinstall hook., Skill file writes reject absolute paths and paths that escape the skill directory., The platform token is a caller-supplied Whalent token sent to the configured Whalent platform, defaulting to memory.whalent.com. ## Affected versions and remediation This report applies to @whalent/agent-core@0.3.470. - Review the evidence and your use of @whalent/agent-core@0.3.470 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.
