arn-infra-ensure-config
This skill should be used when the user says "ensure config", "check arn infra config", "arn-infra-ensure-config", "verify arn infra setup", or wants to verify that Arness Infra configuration is present for the current project. This skill is primarily consumed as a reference by entry-point skills (arn-infra-wizard, arn-infra-assess) which read the ensure-config reference as Step 0 before proceeding with their workflow.

Discovery
89%Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.
The description excels at trigger term coverage and completeness, clearly stating when to use the skill with multiple explicit trigger phrases and explaining its role in the broader workflow. Its main weakness is a lack of specificity about what concrete actions the skill performs beyond 'verifying configuration is present' — it would benefit from listing specific checks or outputs. The relationship to other skills (arn-infra-wizard, arn-infra-assess) is well-articulated, which aids distinctiveness.
Suggestions
Add specific concrete actions the skill performs, e.g., 'checks for config file existence, validates required fields, creates default configuration if missing'.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | The description mentions verifying/ensuring configuration is present and being consumed as a reference by entry-point skills, but the concrete actions (what it actually does when it 'ensures config') are not clearly listed. It names the domain but lacks specific actions like 'creates config file', 'validates settings', etc. | 2 / 3 |
Completeness | The description explicitly answers both 'what' (verify that Arness Infra configuration is present, serve as a reference for entry-point skills) and 'when' (with explicit trigger phrases and use cases). The 'Use when' guidance is clearly stated at the beginning. | 3 / 3 |
Trigger Term Quality | Excellent trigger term coverage with multiple natural phrases: 'ensure config', 'check arn infra config', 'arn-infra-ensure-config', 'verify arn infra setup', and 'verify that Arness Infra configuration is present'. These cover various ways a user might phrase the request. | 3 / 3 |
Distinctiveness Conflict Risk | Highly distinctive with specific product name 'Arness Infra' / 'arn-infra', specific trigger phrases, and a clear niche as a pre-step configuration check. It explicitly names related skills (arn-infra-wizard, arn-infra-assess) to clarify its role, reducing conflict risk. | 3 / 3 |

Implementation
50%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This skill is essentially a thin wrapper that delegates entirely to an external reference file. While it's concise and has a clear reference path, it provides almost no actionable content on its own — no examples, no validation steps, and no preview of what the referenced instructions contain. The skill would benefit from at least summarizing the key checks performed or providing inline fallback guidance.
Suggestions
Include a brief summary of the key checks performed (e.g., 'Checks for valid user profile in ~/.arn-config and ## Arness section in project config') so the skill has standalone value even before reading the reference.
Add at minimum a validation/success criterion (e.g., 'Config is valid when both user profile and ## Arness section are found') to improve workflow clarity.
If the referenced ensure-config.md exists, provide it as a bundle file so the skill can be properly evaluated for progressive disclosure and reference accuracy.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The content is fairly brief but includes some unnecessary explanation (e.g., 'This skill guarantees that a valid user profile...' and 'It runs automatically as Step 0...' and 'When invoked directly...'). These sentences explain context Claude could infer from the description/frontmatter. | 2 / 3 |
Actionability | The skill provides a single concrete instruction (read a specific file and follow its instructions), which is actionable but delegates all real guidance to an external reference file. The skill itself contains no executable steps, commands, or examples. | 2 / 3 |
Workflow Clarity | The workflow is a single step ('read file and follow its instructions'), which is clear but entirely defers to an external file. There are no validation checkpoints, error handling, or feedback loops visible in the skill itself. Since this involves configuration verification (a potentially error-prone operation), the lack of any visible validation steps is a gap. | 2 / 3 |
Progressive Disclosure | The skill references a single external file at a specific path, which is a reasonable one-level-deep reference. However, no bundle files were provided to verify the reference exists, and the skill provides zero context about what the referenced file contains, making navigation harder. The reference path is clear but the skill gives no preview of what to expect. | 2 / 3 |
