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 package has no install-time trigger, but its explicit migration command modifies project agent configuration and adds an always-on rule containing destructive advice. This is a warning-level agent capability risk, not evidence of an active attack.

Static reason

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

Trigger

Run the migration command outside dry-run mode.

Impact

Future Cursor sessions may follow destructive advice and remove project files; the package does not execute that advice itself.

Mechanism

The migration removes src/AGENTS.md and writes a project-local Cursor rule that applies in every session and recommends erasing the working tree after a failed migration.

AI rationale

Evidence

scripts/migrate.tsscripts/migrate/phase-cleanup.tsscripts/migrate/phase-scaffold.tsscripts/migrate/templates/cursor-rules.tssrc/AGENTS.md.cursor/rules/migration-tooling-policy.mdc

Decision evidence

public snapshot

AI called this Suspicious at 91.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

The manifest exposes migration as a CLI and contains no install lifecycle hook.
The migration writes its project configuration and runs provisioning only in execution mode, outside dry run.
Cleanup can delete src/AGENTS.md as part of migration.
Scaffolding writes a project-local Cursor rule that is marked to apply in every session.
The generated rule advises agents to erase the working tree if migration fails; the package does not execute that instruction.
Analytics provisioning requires a supplied Supabase token and uses it for a site metadata update through the Supabase API.

Evidence against

The agent configuration changes require a user to run the migration command; they are not triggered by package installation.
The credential request is for Deco site provisioning through the Supabase API, and no unrelated credential recipient or data collection was established.
