Postinstall detects supported AI clients and installs this package's named skill into their per-user skill directories. This is an automatic first-party agent-extension installation, not a remote payload chain. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 91.0% - **Started:** 2026-08-05T22:05:10.627Z - **Finished:** 2026-08-05T22:05:38.775Z - **Download time:** 768 ms - **Static scan time:** 77 ms - **AI review time:** 27302 ms - **Total time:** 28148 ms ## Security analysis ### Published attack-surface review - **Summary:** Postinstall detects supported AI clients and installs this package's named skill into their per-user skill directories. This is an automatic first-party agent-extension installation, not a remote payload chain. - **Trigger:** npm postinstall; removal on npm preuninstall - **Impact:** Changes AI-agent behavior by adding a documentation/workflow skill; uninstall deletes that same named directory. - **Evidence paths:** package.json, scripts/lib.js, scripts/postinstall.js, scripts/preuninstall.js, scripts/init.js, skills/agentic-sdlc-skill/scripts/sdlc\_core.py - **Review source:** ai\_review - **Reviewed:** 2026-08-05T22:05:38.775Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** copies/removes the bundled agentic-sdlc skill in AI-client skill paths - **Rationale:** The automatic global agent-skill installation is a real extension lifecycle risk, but source inspection supports a bundled first-party setup rather than concrete malicious behavior. Warn under the stated policy. - **Files touched:** scripts/postinstall.js, scripts/preuninstall.js, scripts/lib.js, skills/agentic-sdlc-skill/, ~/.claude/skills/agentic-sdlc/, ~/.gemini/skills/agentic-sdlc/, ~/.gemini/config/skills/agentic-sdlc/, ~/.codex/skills/agentic-sdlc/ ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** package.json runs scripts/postinstall.js automatically., scripts/postinstall.js copies the bundled skill into detected ~/.claude, ~/.gemini, ~/.codex, or Antigravity skill directories., scripts/preuninstall.js recursively removes the same named skill directories. - **Evidence against:** No network, credential harvesting, or exfiltration code found., Installed content is bundled local documentation and Python validation tooling., scripts/init.js filesystem writes occur only through an explicit CLI command., Python subprocess calls are fixed local git queries. ## 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.postinstall = node scripts/postinstall.js ``` ### 2. 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 scripts/postinstall.js ``` ### 3. Low: Non Install Lifecycle Scripts - **Category:** Manifest - **Confidence:** 80.0% Package declares lifecycle scripts that are not normally run for registry tarball installs. ### 4. Low: Scripts Present - **Category:** Manifest - **Confidence:** 100.0% Package declares npm scripts. ### 5. Medium: Environment Vars - **Category:** Source - **Confidence:** 75.0% Package source references environment variables. ### 6. Low: Filesystem - **Category:** Source - **Confidence:** 70.0% Package source references filesystem APIs. ### 7. Critical: Ai Agent Control Hijack - **Category:** Source - **Confidence:** 90.0% - **Path:** scripts/lib.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 Install-time code directly mutates a foreign AI-agent control surface: L74: cmd: 'claude', L75: home: process.env.CLAUDE_CONFIG_DIR || path.join(os.homedir(), '.claude'), L76: envVar: 'CLAUDE_CONFIG_DIR', ...

Low: High Entropy Strings - **Category:** Supply Chain - **Confidence:** 55.0% Package source contains high-entropy string patterns. ### 9. Medium: Ships Build Helper - **Category:** Artifact Inventory - **Confidence:** 70.0% - **Path:** skills/agentic-sdlc-skill/scripts/sdlc\_check.py - **Public source:** [View source]() Package ships non-JavaScript build or shell helper files. Public source snippet (untrusted): ```python path = skills/agentic-sdlc-skill/scripts/sdlc_check.py kind = build_helper sizeBytes = 3084 magicHex = [redacted] ``` ### 10. 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. ### 11. High: Previous Version Dangerous Delta - **Category:** Supply Chain - **Confidence:** 93.0% - **Path:** scripts/init.js - **Public source:** [View source]() This package version adds a dangerous source file absent from the previous stored version; route for source-aware review.
