What it does
Domain Analysis is an agent skill from tech-leads-club/agent-skills. 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).
Its SKILL.md is about 2.9k tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files (for example `EXAMPLES.md`, `QUICK-REFERENCE.md` and `README.md`).
It sits in Development, covering Domain-driven design. The repository describes itself as: The secure, validated skill registry for professional AI coding agents. Extend Antigravity, Claude Code, Cursor, Copilot and more with absolute confidence.
When your agent uses it
- Asking what are the domains in this codebase?
- Where should I draw service boundaries?
- Identify bounded contexts
- Classify subdomains
Example prompts
- “what are the domains in this codebase?”
- “where should I draw service boundaries?”
- “identify bounded contexts”
- “/domain-analysis”
Workflow steps
6 steps, taken from the step headings in SKILL.md.
- Extract Concepts
- Group by Ubiquitous Language
- Identify Subdomains
- Assess Cohesion
- Detect Low Cohesion Issues
- Map Bounded Contexts
What it can do on your machine
Read from SKILL.md and the folder at commit 6df68d5. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are markdown).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Domain Analysis loads about 2.9k tokens when it runs. Until then it costs about 114 tokens; SKILL.md has 911 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 911 words (~2,914 tokens).
“This skill analyzes codebases to identify subdomains (Core, Supporting, Generic) and suggest bounded contexts following Domain-Driven Design Strategic Design principles.”

When should I use Domain Analysis?
Domain Analysis fits situations like: asking what are the domains in this codebase?; where should I draw service boundaries?; identify bounded contexts; classify subdomains.
How do I install Domain Analysis in Claude Code?
Run `npx skills add tech-leads-club/agent-skills --skill domain-analysis -a claude-code`. Or copy the skill folder (packages/skills-catalog/skills/(architecture)/domain-analysis in tech-leads-club/agent-skills) into .claude/skills/domain-analysis in your project. Claude Code loads it when a task matches its description.
How do I install Domain Analysis in Codex?
