arn-spark-ensure-config
This skill should be used when the user says "ensure config", "check arn spark config", "arn-spark-ensure-config", "verify arn spark setup", "configure spark", "setup arness spark", "spark config", or wants to verify that Arness Spark configuration is present for the current project. This skill is primarily consumed as a reference by entry-point skills (arn-brainstorming, arn-spark-discover, arn-spark-arch-vision) 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, providing extensive explicit trigger phrases and clear 'when to use' guidance. It also has strong distinctiveness due to the specific product naming. The main weakness is that the actual capabilities (what 'ensuring config' concretely entails) are somewhat underspecified - it says it verifies configuration is present but doesn't describe what actions it takes if config is missing or what the config contains.
Suggestions
Add specific concrete actions describing what the skill does, e.g., 'Creates default spark.config.yaml if missing, validates required fields (API keys, project ID, environment), and reports configuration status.'
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | The description mentions verifying/ensuring configuration is present and being consumed as a reference by entry-point skills, but doesn't list concrete actions like 'create config file', 'validate settings', or 'set default values'. The actual capabilities remain somewhat vague - what does 'ensure config' actually do? | 2 / 3 |
Completeness | The description explicitly answers both 'what' (verify that Arness Spark configuration is present, serve as a reference for entry-point skills) and 'when' (with a detailed list of trigger phrases and the context of being used as Step 0 by other skills). The 'Use when' guidance is clearly stated. | 3 / 3 |
Trigger Term Quality | Excellent coverage of trigger terms including multiple natural variations: 'ensure config', 'check arn spark config', 'verify arn spark setup', 'configure spark', 'setup arness spark', 'spark config', and the exact skill name. These cover many ways a user might phrase the request. | 3 / 3 |
Distinctiveness Conflict Risk | Highly distinctive with very specific product/tool naming ('Arness Spark', 'arn-spark') and explicit trigger phrases. The description also names the specific skills that consume it, making it very unlikely to conflict with other skills. | 3 / 3 |

Implementation
29%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 redirect to a reference file with no substantive content in the SKILL.md itself. While brevity is valued, this goes too far—it provides no overview of what the ensure-config workflow actually does, no inline steps or validation checkpoints, and the referenced file isn't available in the bundle to compensate. The user or consuming skill gets no useful information from the SKILL.md alone.
Suggestions
Inline at least a summary of the key steps from ensure-config.md (e.g., 1. Check for user profile, 2. Check for ## Arness section, 3. Create if missing) so the SKILL.md provides standalone value.
Add explicit validation checkpoints—what constitutes a 'valid' config, what happens if checks fail, and how errors are handled.
Either include the ensure-config.md reference in the bundle or inline its critical content so the skill is self-contained enough to be useful.
Describe the expected outputs or side effects (e.g., 'After running, ~/.arness-profile and project's ## Arness section will exist') to make the skill actionable without reading the reference.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The content is fairly lean but includes some unnecessary explanation (e.g., 'It runs automatically as Step 0 of all entry-point skills' and 'When invoked directly...' are somewhat redundant given the description). The core instruction is just one line pointing to a reference file. | 2 / 3 |
Actionability | The skill provides a concrete path to a reference file and says to follow its instructions, but the actual actionable content is entirely delegated to that reference file. The SKILL.md itself contains no executable steps, commands, or examples—it's purely a redirect. | 2 / 3 |
Workflow Clarity | There is no workflow described in the SKILL.md itself—just a single instruction to read another file. No steps, no validation checkpoints, no error handling, and no indication of what 'follow its instructions' entails. Since this skill involves configuration verification (a potentially multi-step process), the complete absence of any workflow detail is a significant gap. | 1 / 3 |
Progressive Disclosure | The skill references `ensure-config.md` but no bundle files were provided, making it impossible to verify the reference exists or is well-structured. The SKILL.md is essentially empty content that fully delegates to a single reference with no overview of what that reference contains, providing no navigational value. | 1 / 3 |
