Developer CLI for SMRT framework - introspection, testing, and project management

AI Security Review

scanned 4d ago · by lpm-firewall-ai

No confirmed malicious attack surface was found. Risky primitives are developer CLI features activated by explicit commands, not install-time or import-time compromise.

Static reason

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

Trigger

User runs smrt CLI subcommands

Impact

User-invoked project file generation or command execution within documented CLI workflows

Mechanism

developer tooling for SMRT manifests, docs, templates, git merge drivers, migrations, and playground scaffolding

Rationale

Static inspection shows a broad developer CLI with dynamic imports, child processes, file writes, and template downloads, but these are tied to explicit commands and package-aligned functionality. There are no lifecycle hooks, credential harvesting, hidden exfiltration, persistence, or unconsented foreign AI-agent control-surface writes.

Decision evidence

public snapshot

AI called this Clean at 90.0% confidence as Benign with low false-positive risk.

Evidence for block

Evidence against

package.json has no npm lifecycle install hooks; bin only delegates to dist/index.js via node.
bin/smrt.js spawnSync executes the package CLI entry with inherited argv, not a hidden payload.
dist/index.js lazy-loads command modules and imports project .smrt/register.js or entrypoints only during CLI execution.
dist/commands-gnJG0EIL.js docs:claude writes .claude/smrt-framework.md only when user invokes that command; no install-time agent mutation.
dist/commands-gnJG0EIL.js network access is template download from user-supplied GitHub/GitLab/Bitbucket URLs with HTTPS redirect validation.
dist/commands-gnJG0EIL.js shell/package-manager usage is tied to explicit git, gnode, playground, test, or migration commands.
