Package prompts become discoverable by multiple AI-agent harnesses. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 2.1.0 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. npm postinstall automatically links package-controlled skills and agents into multiple external AI-agent discovery directories. This alters Claude, Pi, and generic agent control surfaces without an explicit user setup command. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 97.0% - **Started:** 2026-08-23T08:35:42.480Z - **Finished:** 2026-08-23T08:36:26.026Z - **Download time:** 517 ms - **Static scan time:** 1071 ms - **AI review time:** 41957 ms - **Total time:** 43546 ms ## Security analysis ### Published attack-surface review - **Summary:** npm postinstall automatically links package-controlled skills and agents into multiple external AI-agent discovery directories. This alters Claude, Pi, and generic agent control surfaces without an explicit user setup command. - **Trigger:** npm install or npm install -g - **Impact:** Package prompts become discoverable by multiple AI-agent harnesses. - **Evidence paths:** package.json, scripts/install-skill.sh, skills/tech-design/SKILL.md, skills/tech-design/agents/tech-design-review.md - **Review source:** ai\_review - **Reviewed:** 2026-08-23T08:36:26.026Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall symlink injection into AI-agent skill and agent directories - **Attack narrative:** Installing the package invokes its postinstall hook. That hook creates symlinks from package-controlled skill and agent content into generic, Claude, and Pi agent discovery directories, causing those harnesses to load package content outside the project scope. The lifecycle script is cross-platform-control-surface mutation rather than an explicit user-invoked setup step. - **Rationale:** The package performs unconsented postinstall mutation of broad, foreign AI-agent control surfaces. This meets the blocking lifecycle-control-surface policy even though no exfiltration endpoint was found. - **Files touched:** scripts/install-skill.sh, skills/tech-design, skills/cw-cli, $HOME/.agents/skills, $HOME/.claude/skills, $HOME/.agents/agents, $HOME/.pi/agent/agents, $HOME/.claude/agents ### Review decision - **Verdict:** Malicious - **Confidence:** 97.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json runs install-skill.sh automatically via postinstall., The lifecycle script targets global .agents, .claude, and .pi agent/skill directories., The script creates symlinks to package-supplied skills and agent prompts in those external control surfaces. - **Evidence against:** No network or credential-exfiltration code was found in inspected lifecycle or entrypoint files., The script avoids overwriting existing non-symlink files and unrelated symlinks. ## Public findings ### 1.

Medium: Ships Build Helper - **Category:** Artifact Inventory - **Confidence:** 70.0% - **Path:** scripts/install-skill.sh - **Public source:** [View source]() Package ships non-JavaScript build or shell helper files. Public source snippet (untrusted): ```shell path = scripts/install-skill.sh kind = build_helper sizeBytes = 4133 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: Suspicious Lifecycle Evidence - **Category:** Manifest - **Confidence:** 97.0% - **Path:** package.json - **Public source:** [View source]() package.json runs install-skill.sh automatically via postinstall. Public source snippet (untrusted): ```json "postinstall": "bash scripts/install-skill.sh", "preuninstall": "bash scripts/uninstall-skill.sh" ``` ### 12. High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 97.0% - **Path:** scripts/install-skill.sh - **Public source:** [View source]() The script creates symlinks to package-supplied skills and agent prompts in those external control surfaces. Public source snippet (untrusted): ```text rm -f "$target" ln -s "$src" "$target" echo "✓ $target → $src" ``` ## Dependencies and install lifecycle - **Lifecycle scripts present:** Yes - **Published lifecycle scripts:** postinstall, preuninstall - **Dependencies:** 2 - **Optional dependencies:** 0 - **Peer dependencies:** 0 - **Development dependencies:** 7 - **Published dependency-graph edges:** 2 ### Published dependency entries - @sinclair/typebox ^0.34.0 (Dependency) - minimist ^1.2.8 (Dependency) ## Package metadata - **Package:** @zhushanwen/coding-workflow - **Ecosystem:** npm - **Version:** 2.1.0 - **License:** MIT - **Version published:** 2026-08-23T08:04:31.705Z - **Package first seen:** 2026-08-03T09:42:28.484Z - **Package last seen:** 2026-08-23T08:36:26.026Z - **Known versions:** 8 - **Latest version:** 2.1.0 - **Appeal under review:** No - **Description:** CI for AI coding agents: event-sourced ledger, evidence gates, and a deterministic runner that turns briefs into verified units - **Runtime engines:** node: \>=20 - **Artifact files:** 190 - **Artifact unpacked size:** 1,018,509 bytes - **Artifact signatures:** 1 - **Attestations:** Yes ## References - [HTML security report]() - [Repository]() - [Homepage]() - [Issues]()
