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

AI Security Review

scanned 5d ago · by lpm-firewall-ai

Source review does not support the scanner's malicious verdict: there is no install hook, and the flagged execution and network behavior belongs to explicit CLI operations or tests. The migration does create a persistent, always-loaded Cursor rule with destructive recovery advice, so a warning is appropriate.

Static reason

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

Trigger

A user runs deco-migrate without dry-run in a site.

Impact

Future Cursor sessions may follow the rule's destructive recovery advice; the cleanup may also remove source-scoped agent instructions.

Mechanism

Migration scaffolding writes an always-loaded Cursor policy pointer, and cleanup may remove the site's src/AGENTS.md file.

AI rationale

Decision evidence

public snapshot

AI called this Suspicious at 79.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

The manifest exposes CLI commands and lists only build, test, typecheck, and lint scripts; it has no install lifecycle hook.
The migration is an explicit command with a dry-run option, and its phases scaffold and clean up the selected site.
Scaffolding writes a project-local Cursor rule marked to load in every session; the rule advises agents to remove the working tree after a failed migration.
Cleanup targets a fixed list of files under the site's source directory, including its AGENTS.md file.
The flagged process and network behavior is tied to selected generators, explicitly gated KV writes, read-only configuration auditing, or test fixtures.

Evidence against

The manifest provides CLI entry points but no preinstall, install, or postinstall command.
The migration rule does not itself execute its destructive advice; it is written during the explicit migration flow.
