Description
Audit Azure NSG rules and Azure Firewall policies for dangerous internet exposure
Usage Guidance
This skill is instruction-only and appears coherent, but take these precautions before using it: (1) Run the az commands locally yourself and review the JSON output — do not paste any credentials, tokens, or connection strings. (2) If you must share data, redact or replace sensitive identifiers and public IPs when possible, or share a sanitized example. (3) Use least-privilege roles locally (Reader is sufficient for many exports; Network Contributor is only needed for some effective-rule queries). (4) The skill will produce recommended CLI commands and tightened JSON — review those before applying them in your environment. (5) Note the skill lists a price and 'pack' metadata in its header; this is informational and not required to run the guidance. If you need the auditor to run commands directly against your subscription, prefer a vetted tool or grant temporary, audited access rather than pasting secrets into chat.
Capability Analysis
Type: OpenClaw Skill
Name: nsg-firewall-auditor
Version: 1.0.0
The skill is explicitly designed as 'instruction-only' and states it 'does not execute any Azure CLI commands or access your Azure account directly.' It instructs the agent to analyze user-provided data and explicitly forbids asking for credentials or secret keys, further instructing the agent to confirm no credentials are included in user-pasted data. While 'bash' is listed as a tool, its implied use is for displaying example commands, not for executing commands based on user-provided data, which is stated to be analyzed by 'Claude'. There is no evidence of malicious intent, data exfiltration, or unauthorized execution in the `SKILL.md` instructions.
Capability Assessment
Purpose & Capability
The name/description match the instructions: the skill asks users to provide az CLI exports (NSG lists, effective rules, firewall policies) and describes checks and remediation. It does not request unrelated credentials, binaries, or access.
Instruction Scope
SKILL.md stays within scope (it instructs the agent to analyze user-provided exports and not to run CLI against the user's account). Minor inconsistency: the front-matter lists 'tools: claude, bash' though the body emphasizes that the skill will not execute Azure CLI — this is likely informational but could confuse less technical users. The skill explicitly warns to confirm exported data contains no credentials before processing.
Install Mechanism
No install spec and no code files — instruction-only, so nothing is written to disk or downloaded. This is the lowest-risk install model and matches the stated behavior.
Credentials
No environment variables, no credentials, and no config paths are requested. The skill requests exported CLI output and recommends minimum RBAC roles for running those CLI commands locally; those requirements are proportionate to the auditing task.
Persistence & Privilege
always is false and model invocation is allowed (platform default). The skill does not request persistent presence or modification of other skills or system-wide settings.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install nsg-firewall-auditor - After installation, invoke the skill by name or use
/nsg-firewall-auditor - Provide required inputs per the skill's parameter spec and get structured output
Version History
