domain-analysis

Maps business domains and suggests service boundaries in any codebase using DDD Strategic Design. Use when asking "what are the domains in this codebase?", "where should I draw service boundaries?", "identify bounded contexts", "classify subdomains", "DDD analysis", or analyzing domain cohesion. Do NOT use for grouping existing components into domains (use domain-identification-grouping) or dependency analysis (use coupling-analysis).

Quality

Content

50%

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

The body is a well-structured, thorough DDD analysis methodology with concrete patterns, a scoring formula, and output templates, but it is verbose with redundant and textbook content and keeps everything inline rather than splitting reference material into bundle files. Every dimension lands at level 2.

Suggestions

Remove textbook DDD explanations (bounded context definition, ubiquitous language, integration pattern glossary) and the duplicated decision tree in Quick Reference to tighten conciseness.

Add a short worked example with filled-in output (a real domain map and cohesion matrix) so the templates become concrete and actionable rather than placeholder-only.

Extract the output format templates, anti-patterns, and quick reference into reference files under references/ and link to them from SKILL.md, plus add an explicit validation checkpoint (e.g. 're-score cohesion after each split') to the phase workflow.

DimensionReasoningScore

Conciseness

The body explains DDD concepts Claude already knows (bounded context, ubiquitous language, the Shared Kernel/Conformist/Anti-corruption Layer integration patterns) and repeats material—the subdomain decision tree appears in both Phase 3 and Quick Reference—but retains enough original methodology to avoid being pure padding, fitting level 2 rather than level 1.

2 / 3

Actionability

It gives concrete scan patterns (`@Entity`, `*Service`, `*Controller`), a numeric cohesion formula, and copy-paste output templates, but the prescribed actions are advisory ("Suggest separation", "Suggest interface-based integration") with no worked example, leaving it short of fully executable guidance at level 3.

2 / 3

Workflow Clarity

The six phases are clearly sequenced and backed by checklists, but there are no explicit validation/feedback checkpoints within the process—checkpoints are implicit rather than the explicit validate→fix→retry loops required for level 3.

2 / 3

Progressive Disclosure

Sections are well organized, but the skill is a single monolithic ~430-line file with no external references at all, and content that could be split out (output templates, anti-patterns, quick reference) is all inline, matching level 2 rather than the one-level-deep referenced structure of level 3.

Description

100%

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 is exemplary: concrete actions, natural trigger phrases, explicit what/when guidance, and proactive disambiguation against sibling skills. It hits the top anchor on every dimension.

DimensionReasoningScore

Specificity

"Maps business domains and suggests service boundaries" lists multiple concrete actions in third person, matching the anchor for several specific actions rather than the partial list at level 2.

3 / 3

Completeness

It clearly states what it does ("Maps business domains and suggests service boundaries in any codebase using DDD Strategic Design") and provides an explicit "Use when asking..." trigger clause, answering both what and when.

3 / 3

Trigger Term Quality

Phrases like "what are the domains in this codebase?", "identify bounded contexts", "classify subdomains", and "DDD analysis" are natural terms a user would actually say, giving good coverage rather than just some relevant keywords.

3 / 3

Distinctiveness Conflict Risk

The explicit "Do NOT use for grouping existing components into domains (use domain-identification-grouping) or dependency analysis (use coupling-analysis)" carves out a clear niche and actively steers away from conflicting skills.
