Installation mutates broad, foreign AI-agent control surfaces in the user's home directory. It deploys package-controlled skills/agents and changes Claude settings by default. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 99.0% - **Started:** 2026-08-10T16:55:33.746Z - **Finished:** 2026-08-10T16:56:11.317Z - **Download time:** 511 ms - **Static scan time:** 8096 ms - **AI review time:** 28963 ms - **Total time:** 37571 ms ## Security analysis ### Published attack-surface review - **Summary:** Installation mutates broad, foreign AI-agent control surfaces in the user's home directory. It deploys package-controlled skills/agents and changes Claude settings by default. - **Trigger:** npm postinstall - **Impact:** Package content becomes available to multiple agent loaders and alters Claude Code's selected output style without explicit setup. - **Evidence paths:** package.json, scripts/install-skills.mjs, dist/cli/index.js, dist/cli/commands/governance-classify-contract-commands.js - **Review source:** ai\_review - **Reviewed:** 2026-08-10T16:56:11.317Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** cross-platform AI-agent skill, agent, output-style, and settings installation - **Attack narrative:** On installation, the postinstall script automatically symlinks package skills into every configured agent platform directory, copies package-controlled agent prompts and output styles into Claude Code directories, and creates or updates ~/.claude/settings.json to select its output style. These are foreign, broad AI-agent control surfaces and are mutated without an explicit user setup command. It also conditionally invokes an automatic project upgrade. - **Rationale:** The concrete postinstall behavior satisfies the blocking policy for unconsented mutation of broad foreign AI-agent control surfaces. No network exfiltration is needed for this install-time control-surface attack. - **Files touched:** scripts/install-skills.mjs, skills/\*\*, agents/\*.md, output-styles/\*.md, ~/.claude/skills/\*, ~/.trae/skills/\*, ~/.trae-cn/skills/\*, ~/.codex/skills/\*, ~/.cursor/skills/\*, ~/.qoder/skills/\*, ~/.tongyi-lingma/skills/\*, ~/.hermes/skills/\*, ~/.openclaw/skills/\*, ~/.zcode/skills/\*, ~/.claude/agents/\*.md, ~/.claude/output-styles/\*.md ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json runs scripts/install-skills.mjs as postinstall., scripts/install-skills.mjs fans out bundled skills into 10 AI-agent home directories without a user command., Postinstall writes bundled agents and output styles, plus ~/.claude/settings.json default outputStyle., Postinstall can spawn \`peaks upgrade --to 2.0 --auto\` based on current-directory state. - **Evidence against:** No credential harvesting, network request, or payload download was found in inspected lifecycle and entrypoint code., Dynamic require in governance command only invokes local git diff when that user-facing command runs. ## Public findings ### 1.
