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

AI Security Review

scanned 5d ago · by lpm-firewall-ai

The source supports a warning for first-party agent configuration that persists into later Cursor sessions and contains destructive advice. Because this setup is user-invoked and no concrete attack behavior is established, block publication is not warranted.

Static reason

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

Trigger

A user runs the exposed `deco-migrate` command on a project.

Impact

Later Cursor sessions may follow the generated destructive advice. The source does not show that the migration itself executes that advice or transfers credentials.

Mechanism

The migration scaffolds a Cursor policy pointer and removes a fixed list of files under the project’s source directory, including `src/AGENTS.md`. The generated rule advises agents to remove the working tree and rerun if migration fails.

AI rationale

Evidence

package.jsonscripts/migrate.tsscripts/migrate/phase-scaffold.tsscripts/migrate/phase-cleanup.tsscripts/migrate/templates/cursor-rules.ts.cursor/rules/migration-tooling-policy.mdcsrc/AGENTS.md

Decision evidence

public snapshot

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

Evidence for warning

The manifest exposes `deco-migrate` as a CLI and declares only build, test, typecheck, and lint scripts.
Running migration calls scaffold and cleanup phases; this setup is user-invoked.
Scaffolding writes an always-applied Cursor policy pointer into the migrated project.
The generated guidance tells agents to remove the working tree and rerun after a failed migration.
Cleanup includes `src/AGENTS.md` in its fixed deletion list.

Evidence against

The Cursor rule is created during the explicit migration command, and the manifest has no install lifecycle script.
The generated rule points to the project’s canonical migration policy; the inspected code does not establish remote code execution or credential transfer.
