Deco codegen (generate-blocks, generate-schema, generate-invoke) and Fresh-to-TanStack migration tooling

AI Security Review

scanned 4mo ago · by lpm-firewall-ai

Source inspection does not support the scanner's malicious verdict, but the explicit user-command Cursor rule scaffolding is a real agent control-surface lifecycle risk worth warning on. The behavior is first-party and migration-aligned, so it should not block publication.

Static reason

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

Trigger

User runs deco-migrate or related CLI commands

Impact

Project files may be rewritten and a first-party Cursor policy pointer rule is added; no stealth exfiltration or remote payload execution found.

Mechanism

explicit migration scaffolding and project bootstrap

AI rationale

Decision evidence

public snapshot

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

Evidence for warning

scripts/migrate/phase-scaffold.ts writes .cursor/rules/migration-tooling-policy.mdc during the explicit deco-migrate command.
scripts/migrate/templates/cursor-rules.ts creates an alwaysApply Cursor rule with upstream policy links and process instructions.
scripts/migrate.ts bootstraps migrated projects by running bun install and codegen commands after user-invoked migration.

Evidence against

package.json has no preinstall/install/postinstall lifecycle hooks.
Network use is package-aligned: Cloudflare KV sync, optional user-supplied cache purge, npm version lookup, and documentation links.
scripts/generate-blocks.ts only reads .deco/blocks JSON and writes generated .deco artifacts.
child_process use is in explicit migration/CI utilities or tests, not install-time execution.
No credential harvesting or exfiltration beyond documented env vars used for Cloudflare KV/API auth.
