It installs agent instructions, MCP wiring, and command hooks that run in later Claude sessions. - **Trigger:** npm install of the package in a project with package.json - **Impact:** Alters a foreign AI-agent's project behavior and executes package-controlled hook commands on agent events. - **Evidence paths:** package.json, bin/construct-postinstall.mjs, lib/install/stage-project.mjs, scripts/sync-worker-profiles.mjs, platforms/claude/settings.template.json - **Review source:** ai\_review - **Reviewed:** 2026-07-31T09:57:38.610Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall stages Construct launcher and Claude agent/hook configuration - **Attack narrative:** On npm installation, the postinstall hook stages a launcher and runs the adapter synchronizer in the consumer project. The synchronizer writes Claude Code agent configuration, project settings containing command hooks, and MCP configuration. Those hooks later invoke package-controlled code for Claude tool events. This is an unconsented install-time mutation of a foreign AI-agent control surface. - **Rationale:** The lifecycle hook creates and configures a consumer project's Claude Code control surface automatically. Under the install-control-surface policy, this concrete behavior requires blocking even though no secret exfiltration was confirmed. - **Files touched:** \/.construct/run.mjs, \/.construct/install-manifest.json, \/.claude/agents/construct.md, \/.claude/settings.json, \/.mcp.json, \/.gitignore ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json runs bin/construct-postinstall.mjs on postinstall., bin/construct-postinstall.mjs automatically stages adapters in the consumer project., lib/install/stage-project.mjs invokes scripts/sync-worker-profiles.mjs during install., scripts/sync-worker-profiles.mjs writes project .claude settings, agents, and .mcp.json., platforms/claude/settings.template.json installs command hooks for Claude tool events. - **Evidence against:** Global machine-scope setup is skipped during global install., No credential exfiltration was confirmed in the postinstall path., The hook declares a mutation receipt and recovery command. ## Public findings ### 1.
