The default npm postinstall only restores an in-package build stamp and reports setup guidance. With an explicit environment opt-in, it modifies global agent tooling and registers a Context7 MCP server. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 93.0% - **Started:** 2026-08-09T15:26:48.332Z - **Finished:** 2026-08-09T15:27:37.520Z - **Download time:** 505 ms - **Static scan time:** 8936 ms - **AI review time:** 39745 ms - **Total time:** 49188 ms ## Security analysis ### Published attack-surface review - **Summary:** The default npm postinstall only restores an in-package build stamp and reports setup guidance. With an explicit environment opt-in, it modifies global agent tooling and registers a Context7 MCP server. - **Trigger:** npm install with SKS\_POSTINSTALL\_BOOTSTRAP=1 - **Impact:** Adds persistent agent-extension content and an MCP command to the user's Codex environment. - **Evidence paths:** package.json, dist/bin/sks.js, dist/cli/install-helpers.js, dist/cli/install-helpers-install-support.js, dist/core/init/skills.js, dist/core/mcp/mcp-config-preservation.js - **Review source:** ai\_review - **Reviewed:** 2026-08-09T15:27:37.520Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** opt-in global Codex skill and MCP bootstrap - **Rationale:** Not malicious under the install-control policy because foreign agent-surface mutation requires explicit lifecycle opt-in. It remains a meaningful agent-extension lifecycle risk when that opt-in is used. - **Files touched:** dist/.sks-build-stamp.json, ~/.agents/skills, ~/.codex/config.toml - **Network endpoints:** https://mcp.context7.com/mcp ### Review decision - **Verdict:** Suspicious - **Confidence:** 93.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** package.json runs dist/bin/sks.js postinstall., Opt-in postinstall creates a global sks shim and installs global agent skills., Opt-in postinstall invokes \`codex mcp add context7 -- npx -y @upstash/context7-mcp@latest\`., Generated skills can affect Codex agent behavior. - **Evidence against:** Default postinstall returns before external mutation unless SKS\_POSTINSTALL\_BOOTSTRAP=1., Default path states project, HOME, Codex, and global SKS state remain unchanged., Context7 subprocess clears CODEX\_LB\_API\_KEY., No credential collection or exfiltration was found in reviewed lifecycle sources. ## Public findings ### 1.
