AI Security Review

scanned 1d ago · by lpm-firewall-ai

LPM treats this as warn-only first-party agent extension lifecycle risk. Explicit CLI invocation can install a SpecShip MCP server and hook commands into Claude Code configuration. With `--yes`, it defaults to project-local configuration and enables auto-allow; normal installation prompts first. No npm lifecycle hook activates this behavior during package installation.

Static reason

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

Trigger

User runs `specship` without arguments or invokes `specship install`, including optional `--yes` flags.

Impact

Persists package-owned `specship` commands in `.mcp.json` and Claude settings; hooks run `specship sync --quiet` or `specship spec-nudge`.

Mechanism

CLI-driven Claude Code MCP, permission, and hook configuration.

Rationale

Source inspection found no malicious payload, credential exfiltration, or unconsented npm install-time mutation. The explicit CLI installer persists agent configuration and auto-executing package commands, which meets the policy’s warning boundary for first-party agent extension lifecycle risk.

Decision evidence

public snapshot

AI called this Suspicious at 91.0% confidence as Dangerous Capability with low false-positive risk.

Evidence for warning

`lib/dist/bin/specship.js` invokes the installer when run with no arguments.
`lib/dist/installer/index.js` supports noninteractive `--yes`, defaulting to local Claude config and auto-allow.
`lib/dist/installer/targets/claude.js` writes SpecShip MCP, permissions, and package-owned hooks.
`lib/dist/hooks/hooks.json` configures `sync --quiet` and `spec-nudge` hook commands.
`lib/dist/update/run-installer.js` spawns a global npm upgrade only through `specship update`.

Evidence against

`package.json` has no `preinstall`, `install`, or `postinstall` hook.
`bin/specship.cmd` only launches the bundled Node runtime and CLI.
Installer source presents prompts for global install, location, and auto-allow unless `--yes` is supplied.
Inspected network code is update/Jira functionality; no credential harvesting or exfiltration chain was found.
No source shows remote payload execution, stealth persistence, or destructive behavior.
