SpecShip self-contained bundle for darwin-arm64

AI Security Review

scanned 6d ago · by lpm-firewall-ai

LPM treats this as warn-only first-party agent extension lifecycle risk. No unconsented npm lifecycle attack surface was confirmed. The package is an explicit Claude Code/SpecShip integration that can add MCP config, permissions, hooks, commands, a subagent, and optional git hooks when the user runs its installer.

Static reason

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

Trigger

User runs `specship install` or related CLI commands.

Impact

Adds agent-facing capabilities and background sync commands in Claude/project config; residual risk is guarded extension lifecycle behavior rather than malware.

Mechanism

User-invoked Claude Code/MCP extension setup with optional auto-allow and sync hooks.

Policy narrative

The package ships a self-contained SpecShip CLI and native Node runtime. Its installer can configure Claude Code with a SpecShip MCP server, auto-allowed SpecShip tools, slash commands, a subagent, status-line support, and optional sync hooks. These are agent-control-surface changes, but inspection shows they are invoked through explicit CLI install flows rather than npm lifecycle hooks or import-time code.

Rationale

Because the risky Claude/MCP and hook writes are user-invoked and package-aligned, this does not meet the block threshold for unconsented lifecycle control hijack. It still warrants a warning as guarded agent extension lifecycle risk with auto-allow and hook-writing capability.

Decision evidence

public snapshot

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

Evidence for warning

`lib/dist/installer/targets/claude.js` writes Claude MCP config, permissions, hooks, slash commands, and a subagent on `specship install`.
`lib/dist/installer/targets/shared.js` auto-allows multiple `mcp__specship__*` tools when permissions are enabled.
`lib/dist/sync/git-hooks.js` can install git post-commit/post-merge/post-checkout hooks that run `specship sync`.
`lib/dist/installer/index.js` may run `npm install -g @specship/specship`, but only after interactive confirmation.

Evidence against

`package.json` has no npm lifecycle scripts, so install-time execution is not established.
Agent config writes are reached through explicit `specship install`, with local default and prompts unless `--yes` is supplied.
MCP command is package-aligned: `specship serve --mcp`, not a remote or foreign payload.
No credential harvesting or exfiltration endpoint was found in inspected entrypoints.
Native `node` binary is a bundled darwin-arm64 runtime launched by `bin/specship` to run the package CLI.
