Discovery
7%Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.
This description is extremely weak, essentially just restating the skill name with no substantive content. It lacks concrete actions, meaningful trigger terms, and any 'Use when...' guidance. It would be nearly indistinguishable from other GCP or networking skills in a large skill library.
Suggestions
Add specific concrete actions the skill performs, e.g., 'Generates GCP VPC firewall rules including ingress/egress configurations, port specifications, IP range allowlists, and service account-based targeting.'
Add an explicit 'Use when...' clause with natural trigger terms, e.g., 'Use when the user asks about creating firewall rules, configuring network access, allowing or blocking traffic on specific ports, or setting up VPC security policies in Google Cloud Platform.'
Remove the duplicate trigger term ('firewall rule generator' is listed twice) and expand with varied natural language terms users might say, such as 'network rules', 'allow SSH', 'open port', 'GCP firewall', 'VPC rules'.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | The description only names the skill ('Firewall Rule Generator') and mentions GCP, but does not describe any concrete actions like 'creates ingress/egress rules', 'configures ports', or 'sets up network policies'. It is essentially just a title repeated. | 1 / 3 |
Completeness | The description fails to answer 'what does this do' beyond the title and completely lacks a 'when should Claude use it' clause with explicit triggers. Both dimensions are very weak. | 1 / 3 |
Trigger Term Quality | The trigger terms are just 'firewall rule generator' repeated twice. It misses natural user phrases like 'firewall rules', 'network security', 'allow traffic', 'block port', 'VPC firewall', 'GCP firewall', or 'ingress/egress rules'. | 1 / 3 |
Distinctiveness Conflict Risk | The mention of 'GCP' and 'firewall rule' provides some specificity that distinguishes it from generic networking skills, but the lack of detail about what kind of firewall rules or specific GCP services means it could overlap with other GCP networking or security skills. | 2 / 3 |
Total | 5 / 12 Passed |
Implementation
0%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This skill is an empty shell with no substantive content. It consists entirely of generic boilerplate that describes what a firewall rule generator skill would do without providing any actual instructions, code, examples, or GCP-specific guidance. It fails on every dimension of the rubric.
Suggestions
Add concrete, executable examples of GCP firewall rule generation using `gcloud compute firewall-rules create` commands with specific flags and common configurations (e.g., allow SSH, HTTP, internal traffic).
Include a workflow with validation steps, such as listing existing rules before creation, using `--dry-run` or preview modes, and verifying rules after creation with `gcloud compute firewall-rules describe`.
Provide example firewall rule configurations in both CLI and Terraform/JSON format covering common patterns (ingress/egress, priority ordering, service account-based rules).
Remove all generic boilerplate ('This skill provides automated assistance...', 'Example Triggers', etc.) and replace with actionable content that teaches Claude how to generate correct GCP firewall rules.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The content is entirely filler and boilerplate. It explains nothing Claude doesn't already know, repeats 'firewall rule generator' excessively, and provides zero substantive information about actually generating firewall rules. | 1 / 3 |
Actionability | There is no concrete guidance whatsoever—no code, no commands, no GCP CLI examples, no firewall rule schemas, no configuration snippets. It only describes what the skill supposedly does without actually doing it. | 1 / 3 |
Workflow Clarity | No workflow is defined. There are no steps, no sequencing, no validation checkpoints. The phrase 'step-by-step guidance' is claimed but never delivered. | 1 / 3 |
Progressive Disclosure | The content is a flat, monolithic block of generic placeholder text with no references to detailed files, no structured navigation, and no meaningful content organization. | 1 / 3 |
Total | 4 / 12 Passed |
Validation
81%Checks the skill against the spec for correct structure and formatting. All validation checks must pass before discovery and implementation can be scored.
