Discovery

40%

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 identifies a clear, narrow task (adding a config field to datadog.yaml) which gives it strong distinctiveness, but it lacks a 'Use when...' clause and provides only a single action without elaboration. It would benefit significantly from explicit trigger guidance and additional detail about what the process involves.

Suggestions

Add a 'Use when...' clause with trigger terms like 'when the user needs to add a new setting to the Datadog Agent config', 'datadog.yaml field', 'agent configuration option'.

Expand the capability description with more concrete actions, e.g., 'Adds a new configuration field to datadog.yaml, including defining the field schema, setting defaults, adding documentation comments, and wiring it into the agent's config parsing logic'.

Include common keyword variations users might use such as 'config option', 'agent setting', 'YAML parameter', 'Datadog config' to improve trigger term coverage.

DimensionReasoningScore

Specificity

Names a specific domain (Datadog Agent configuration) and one action (add a configuration field), but does not list multiple concrete actions or elaborate on what adding a field entails.

2 / 3

Completeness

Describes what the skill does (add a configuration field) but completely lacks any 'Use when...' clause or explicit trigger guidance for when Claude should select this skill. Per rubric guidelines, a missing 'Use when' clause caps completeness at 2, and since the 'what' is also thin, this scores a 1.

Trigger Term Quality

Includes relevant keywords like 'Datadog Agent', 'datadog.yaml', and 'configuration field', but misses common variations users might say such as 'config option', 'agent setting', 'YAML config', or 'new parameter'.

2 / 3

Distinctiveness Conflict Risk

The description targets a very specific niche — adding configuration fields to the Datadog Agent's datadog.yaml — which is unlikely to conflict with other skills due to the narrow, product-specific scope.

Implementation

92%

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

This is a high-quality skill that provides precise, project-specific guidance for adding configuration fields to the Datadog Agent. Its greatest strengths are the comprehensive subsystem mapping tables, concrete code examples, and clear verification steps. The only minor weakness is that the reference tables could potentially be split into a separate file for better progressive disclosure, though the current organization is still quite readable.

DimensionReasoningScore

Conciseness

The content is lean and efficient. Every table, code snippet, and note earns its place. It doesn't explain what Go is, what YAML is, or how config files work—it assumes Claude's competence and focuses entirely on project-specific knowledge Claude wouldn't have.

3 / 3

Actionability

Provides concrete, executable Go code for registering config keys, specific build/lint commands, exact file paths, and method signatures with real examples. The step-by-step process includes specific commands like `dda inv agent.build --build-exclude=systemd` and patterns like `BindEnvAndSetDefault("my_feature.timeout", 30, "DD_MY_TIMEOUT")`.

3 / 3

Workflow Clarity

The 4-step workflow is clearly sequenced: gather info → register key → optionally document → verify. Step 4 includes explicit build, lint, and config generation validation steps. The information-gathering step has a clear checklist of 8 items, and the skill includes decision points (e.g., serverless-compatible fields, dedicated setup file vs inline).

3 / 3

Progressive Disclosure

The content is well-structured with tables and clear sections, but it's all inline in a single file. The tables for subsystems are useful reference material that could be split into a separate reference file. However, given no bundle files exist, the skill does a reasonable job organizing content with headers and tables, though it's on the longer side for a single file.
