SpecShip self-contained bundle for win32-arm64

AI Security Review

scanned 3d ago · by lpm-firewall-ai

LPM treats this as warn-only first-party agent extension lifecycle risk. No confirmed malicious install-time attack surface. The package is an agent/Claude Code extension that can write Claude MCP, settings, hooks, commands, agents, and project index files when the user runs the CLI installer.

Static reason

One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source

Trigger

User runs specship or specship install

Impact

Adds SpecShip MCP tools and auto-sync hooks to Claude/project configuration; no unconsented npm lifecycle mutation found.

Mechanism

user-invoked Claude Code extension setup

Rationale

Static inspection shows a package-aligned Claude/SpecShip extension installer with broad agent-control writes, but they are user-invoked and there is no npm lifecycle hook or covert exfiltration behavior. This fits guarded agent extension lifecycle risk rather than malicious lifecycle hijack.

Evidence

Decision evidence

public snapshot

AI called this Suspicious at 86.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

User-invoked installer writes Claude MCP config to ~/.claude.json or ./.mcp.json.
Installer can add Claude settings permissions and hooks running specship sync/spec-nudge.
Installer copies package slash commands and agent markdown into Claude commands/agents dirs.
Local install can initialize .specship and optionally install git sync hooks when watcher is disabled.

Evidence against

Top-level package.json has no npm lifecycle scripts or bin entry; install-time execution is not present.
bin/specship.cmd only launches bundled node.exe with lib/dist/bin/specship.js.
CLI installer is activated by running specship with no args or install flags, not by npm install.
MCP command is package-aligned: specship serve --mcp; permissions are specship MCP tools.
No credential harvesting or exfiltration endpoint found in inspected installer/CLI paths.
