Flutter Updater

Security checks across malware telemetry and agentic risk

Overview

This Flutter updater has a clear purpose, but it asks the agent to run multiple helper programs that are not included in the reviewed package before making project changes.

Review before installing. Use only in a version-controlled Flutter/Dart project, and do not run it unless you trust the source of the flutter-updater helper binaries it will execute. Expect dependency upgrades, source edits, dart fix, tests, builds, network lookups for releases/changelogs, local state writes, and a report file.

Vague Triggers

Medium

Confidence: 90% confidence
Finding: The invocation phrases are broad enough to match routine maintenance requests like 'update dependencies' or 'upgrade packages', which can cause the skill to run in situations where the user may not expect SDK upgrades, code edits, tests, builds, or report generation. In this skill, that ambiguity is more dangerous because execution performs substantial file modifications and external tooling actions, increasing the chance of unintended changes.

Missing User Warnings

Medium

Confidence: 95% confidence
Finding: The description advertises automated updating but does not clearly warn that the skill will modify project files, run package upgrades, execute analyze/test/build commands, and save reports to disk. This lack of up-front disclosure can mislead users into invoking a high-impact automation workflow without informed consent.
