SpecShip self-contained bundle for linux-arm64

AI Security Review

scanned 4h ago · by lpm-firewall-ai

LPM treats this as warn-only first-party agent extension lifecycle risk. No install-time malicious behavior is established, but the package provides an explicit installer for a Claude Code MCP extension. It can add package-owned auto-allowed MCP permissions and hooks after user invocation.

Static reason

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

Trigger

User runs specship with no args, specship install, specship update, or specship uninstall.

Impact

Claude Code may auto-run SpecShip sync/status/nudge commands and allow SpecShip MCP tools; update may install latest SpecShip globally.

Mechanism

first-party Claude Code MCP extension setup and self-update commands

Rationale

Source inspection shows potentially risky agent-extension lifecycle behavior, but it is first-party and user-invoked with no package lifecycle hook. This fits a warn-level agent extension risk rather than malicious publish blocking.

Evidence

Decision evidence

public snapshot

AI called this Suspicious at 82.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

lib/dist/bin/specship.js runs installer when invoked with no args, not via npm lifecycle.
lib/dist/installer/targets/claude.js writes Claude MCP config, permissions, hooks, slash commands, subagent, and optional status line.
lib/dist/installer/targets/shared.js auto-allows mcp__specship__ tools including designer_* tools.
lib/dist/installer/index.js can run npm install -g @specship/specship during interactive install and update flows.
lib/dist/update/run-installer.js spawns npm i -g @specship/specship@latest or shell install command only through specship update.

Evidence against

package.json has no preinstall/install/postinstall lifecycle hooks.
bin/specship only execs bundled node with lib/dist/bin/specship.js on explicit user invocation.
Installer prompts unless --yes/flags are supplied and targets first-party SpecShip Claude integration.
Claude writes are scoped to specship entries and marker-owned hooks/commands; uninstall removes matching owned entries.
JIRA credentials are saved only via explicit specship jira configure and chmod 0600.
No hardcoded exfiltration endpoint or credential harvesting loop found in inspected files.
