Confirmed finding summary

No confirmed security findings

The completed audit recorded no confirmed security findings. This is not proof that the Skill has no side effects.

Installation context

Historical evidence

This report may not describe the currently installable artifact. Open the current Skill page for install guidance.

Open current Skill page

This report does not block or authorize the manifest or ZIP.

Static analysis reported external command, network, key, storage, reconnaissance, and weak-crypto patterns, but review found documentation-only Flutter and Dart examples. No code executes automatically, no secrets are accessed, and no prompt injection text was found.

Limitations

This report does not claim runtime or sandbox execution and does not prove the absence of side effects.

Evidence chain

Follow the evidence from source binding to the install contract. Available evidence supports verification; it is not a safety guarantee.

False Positive: Markdown Backticks Flagged as Command Execution
The external command alerts point to Markdown code fences, inline reference paths, Dart snippets, and Flutter CLI documentation. These examples are inert skill content and do not run commands automatically.
The reviewed locations are Markdown fences or inline code references. The only shell commands are Flutter profiling examples in documentation, with no autonomous execution path.

False Positive: Flutter Key Syntax Flagged as Credential Material
The certificate and key alerts match Flutter widget constructor syntax such as super.key, Key, and route query key terms. No private keys, certificates, or credential files are present.
Every cited occurrence is ordinary Flutter API syntax or documentation table text. There is no secret value, encoded material, or file path to credential artifacts.

False Positive: Weak Crypto Alerts Match Ordinary Words
The weak cryptography alerts match ordinary documentation text, including description, auth guidance, and desktop layout terms. No MD5, SHA1, DES, or cryptographic API use was found.
Manual review of the static locations found natural language and UI layout identifiers. There is no implementation of cryptographic functions or insecure algorithm selection.

False Positive: System Reconnaissance Alerts Match Dart Examples
The reconnaissance alerts occur inside Flutter routing and state-management examples, such as route parameters, Todo methods, and widget callbacks. They do not inspect host system information.
The reviewed lines are application sample code, not shell commands or host probes. No uname, whoami, environment enumeration, or filesystem reconnaissance behavior appears.
Low
SKILL.md:6
False Positive: Hardcoded URL Is Author Metadata
The network alert is a GitHub author URL in skill metadata. It is not a runtime endpoint and no data is sent to it by the skill.
The URL appears only in frontmatter metadata as the author attribution. There is no fetch, HTTP client, webhook, or exfiltration path associated with it.
Low
references/project-structure.md:69-71references/project-structure.md:87
False Positive: Storage References Are Architecture Guidance
The browser storage alert matches Flutter dependency and architecture guidance for shared preferences, Hive, and data layer responsibilities. The skill itself does not access browser storage.
The lines describe Flutter project structure and dependency choices. No executable code reads cookies, localStorage, sessionStorage, or browser credentials.
