The explicit CLI scaffolds packaged workflow prompts and rules into project AI-agent control paths. The postinstall entrypoint exits without making these changes during npm lifecycle execution. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 94.0% - **Started:** 2026-08-17T03:26:23.032Z - **Finished:** 2026-08-17T03:27:29.094Z - **Download time:** 258 ms - **Static scan time:** 158 ms - **AI review time:** 65645 ms - **Total time:** 66062 ms ## Security analysis ### Published attack-surface review - **Summary:** The explicit CLI scaffolds packaged workflow prompts and rules into project AI-agent control paths. The postinstall entrypoint exits without making these changes during npm lifecycle execution. - **Trigger:** Explicit npx/CLI invocation outside an npm automatic lifecycle event - **Impact:** Installed rules can influence Claude, Gemini, or Cursor behavior in the target project. - **Evidence paths:** package.json, dist/install.js, dist/install/command-adapters.js, dist/bundle.json - **Review source:** ai\_review - **Reviewed:** 2026-08-17T03:27:29.094Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** project-local AI-agent workflow scaffolding - **Rationale:** The package has a guarded, explicit-user-command agent configuration capability. It warrants a warning for extension lifecycle risk, not a block, because automatic npm installation is a no-op. - **Files touched:** AGENTS.md, .agents/configs/subagents.json, .cursor/rules/ai-workflow.mdc ### Review decision - **Verdict:** Suspicious - **Confidence:** 94.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** Manifest invokes installer at postinstall., Explicit installer writes packaged templates into agent command/rule paths., Installer provisions shared and vendor-specific AI-agent configuration directories. - **Evidence against:** All npm automatic lifecycle events are detected and exit before scaffolding., Reviewed executable sources contain no network client, credential harvesting, eval, or remote payload execution., Existing files are skipped unless --force is supplied; forced replacements back up by default. ## Public findings ### 1. High: Install Time Lifecycle Scripts - **Category:** Manifest - **Confidence:** 90.0% - **Path:** package.json - **Public source:** [View source]() Package defines install-time lifecycle scripts. Public source snippet (untrusted): ```json scripts.preinstall = node -e "const f=require('fs'),{execSync}=require('child_process');if(!f.existsSync('dist/install.js')&&f.existsSync('scripts/build.js'))execSync('node scripts/build.js',{stdio:'in... ``` ### 2. Critical: Red Install Lifecycle Script - **Category:** Manifest - **Confidence:** 95.0% - **Path:** package.json - **Public source:** [View source]() Install-time lifecycle script matches a deterministic static-gate block pattern. Public source snippet (untrusted): ```json scripts.preinstall = node -e "const f=require('fs'),{execSync}=require('child_process');if(!f.existsSync('dist/install.js')&&f.existsSync('scripts/build.js'))execSync('node scripts/build.js',{stdio:'in... ``` ### 3. Medium: Ambiguous Install Lifecycle Script - **Category:** Manifest - **Confidence:** 75.0% - **Path:** package.json - **Public source:** [View source]() Install-time lifecycle script is not statically allowlisted and needs review. Public source snippet (untrusted): ```json scripts.postinstall = node dist/install.js ``` ### 4. Low: Non Install Lifecycle Scripts - **Category:** Manifest - **Confidence:** 80.0% Package declares lifecycle scripts that are not normally run for registry tarball installs. ### 5. Low: Scripts Present - **Category:** Manifest - **Confidence:** 100.0% Package declares npm scripts. ### 6. Medium: Dynamic Require - **Category:** Source - **Confidence:** 75.0% - **Path:** dist/install.js - **Public source:** [View source]() Package source references dynamic require/import behavior. Public source snippet (untrusted): ```javascript L10: L11: const fs = require('fs'); L12: const path = require('path'); ``` ### 7. Medium: Environment Vars - **Category:** Source - **Confidence:** 75.0% Package source references environment variables. ### 8. Low: Filesystem - **Category:** Source - **Confidence:** 70.0% Package source references filesystem APIs. ### 9. Critical: Ai Agent Control Hijack - **Category:** Source - **Confidence:** 90.0% - **Path:** dist/install.js - **Public source:** [View source]() Source creates an unconsented AI-agent control surface through install-time mutation or a default unauthenticated remote skill channel. Public source snippet (untrusted): ```javascript L175: function listSkillTemplateEntries() { L176: const skillPathRe = /^\.agents\/skills\/[^/]+\/SKILL\.md$/; L177: const bundle = getBundleFiles(); ... L183: } L184: const skillsDir = path.join(templateRoot, '.agents', 'skills'); L185: if (!fs.existsSync(skillsDir)) return []; ... L192: return { L193: relativePath: `.agents/skills/${name}/SKILL.md`, L194: content: fs.readFileSync(skillFile, 'utf8') ... L201: function listCommandTemplateEntries() { L202: const prefix = '.agents/commands/'; L203: const bundle = getBundleFiles(); ``` ### 10. Low: High Entropy Strings - **Category:** Supply Chain - **Confidence:** 55.0% Package source contains high-entropy string patterns. ### 11. Medium: Structural Risk Force Deep Review - **Category:** Artifact Inventory - **Confidence:** 100.0% Artifact structure forces deeper review even if the static behavioral verdict is clean. ### 12. Medium: Suspicious Lifecycle Evidence - **Category:** Manifest - **Confidence:** 94.0% - **Path:** package.json - **Public source:** [View source]() Manifest invokes installer at postinstall.
