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.

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

Most static findings are false positives from Markdown examples, Firestore Rules syntax, or defensive security guidance. Five findings are confirmed because SKILL.md instructs agents to run Firebase CLI commands through npx, including metadata reads and database creation. No evidence found of prompt injection, credential exfiltration, or malicious intent.

Capability review items (5)
Medium
SKILL.md:9
Ruby/shell backtick execution
compatibility: This skill is best used with the Firebase CLI, but does not require it. Firebase CLI
The skill directs agents to access Firebase CLI through npx, which installs and executes external tooling. This is legitimate but requires user confirmation because it reaches npm and Firebase services.
Medium
SKILL.md:19-20
Ruby/shell backtick execution
Run the following command to list current Firestore databases: `bash npx -y
The skill tells the agent to run firebase-tools through npx to list Firestore databases. This executes external networked tooling and may expose project metadata.
Medium
SKILL.md:24-25
Ruby/shell backtick execution
1. For each database found, inspect its edition and details: `bash npx -y
The skill tells the agent to query Firestore database details with firebase-tools. This executes external CLI tooling and reads cloud project metadata.
Medium
SKILL.md:38
Ruby/shell backtick execution
Run `npx -y firebase-tools@latest firestore:locations` to get the list of options.
The skill directs the agent to run firebase-tools to retrieve Firestore locations. This is a benign Firebase query but still executes external networked tooling.
Medium
SKILL.md:42
Ruby/shell backtick execution
`bash npx -y firebase-tools@latest firestore:databases:create <database-id> --edition="enterprise" -
The skill instructs database creation with firebase-tools. This can mutate cloud resources and should require explicit user approval for project, database, edition, and location.

Risk findings

Confirmed security concerns are separated from items that still need review.

No confirmed security findings were recorded for this completed audit.

Remediation

Suggested fixes recorded by this audit. Applying them is the maintainer’s responsibility.

  1. FIX-001
    Medium
    External Firebase CLI commands may run without enough confirmation.
    Require explicit user approval before running npx or firebase commands, and show the target project and database first.
  2. FIX-002
    Medium
    Database creation can mutate cloud resources.
    Confirm project, database ID, edition, location, and expected impact before creating or deploying Firestore resources.
  3. FIX-003
    Low
    firebase-tools@latest can change behavior over time.
    Recommend a pinned or user-approved Firebase CLI version for reproducible workflows.
