Quality

Content

79%

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

This is a strong, actionable skill with excellent conciseness and concrete guidance. The subsystem mapping tables are particularly well-done, providing quick lookup without verbosity. The main weaknesses are the lack of explicit validation checkpoints between steps (especially after schema regeneration) and the absence of progressive disclosure via supporting bundle files for the reference tables.

Suggestions

Add a validation checkpoint after Step 3 (e.g., verify the new key appears in the generated YAML schema before committing)

Consider extracting the subsystem tables and method reference into a separate REFERENCE.md bundle file to keep the main skill focused on the workflow

Dimension	Reasoning	Score
Conciseness	The content is lean and well-structured. The tables efficiently convey subsystem mappings without unnecessary prose. It assumes Claude knows Go, YAML, and build tooling, and avoids explaining basic concepts.	3 / 3
Actionability	Provides concrete Go code snippets (BindEnvAndSetDefault), specific bash commands for schema regeneration and linting, exact file paths, and clear method signatures. The guidance is copy-paste ready and specific.	3 / 3
Workflow Clarity	The four steps are clearly sequenced and the workflow is logical. However, there's no explicit validation/feedback loop after Step 2 (e.g., verifying the key registered correctly) or after Step 3 (verifying the schema output is correct before committing). The lint step in Step 4 is a partial checkpoint but error recovery guidance is missing.	2 / 3
Progressive Disclosure	The content is well-organized with tables and sections, but it's somewhat monolithic — the subsystem tables and method reference could be split into separate reference files. No bundle files exist to offload detailed reference material, and the skill doesn't reference any external docs for advanced patterns.	2 / 3

Description

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 'add config option to datadog.yaml', 'new Datadog Agent setting', 'agent configuration parameter'.

List more specific actions involved, 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 config struct'.

Include common keyword variations users might use such as 'config option', 'agent setting', 'YAML parameter', 'datadog config'.

Dimension	Reasoning	Score
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 a 'Use when...' clause or any explicit trigger guidance for when Claude should select this skill. Per rubric guidelines, missing 'Use when' caps completeness at 2, and the 'what' is also minimal, warranting a 1.	1 / 3
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.	3 / 3
