Create an immutable value object. Use when modeling concepts without identity like Money, Email, Address. Use this skill for any domain concept defined by its attributes rather than identity — CPF, CRM, phone numbers, date ranges, or any value requiring validation and formatting. Dispatch hub — routes to typescript/go variants by file extension.

Value Object
Immutable concept defined by its value rather than identity (Email, Money, CPF, CRM, DateRange). Self-validating on construction — an invalid VO never exists. Lives inside entities.
The shape and idioms of this primitive differ per backend language; the lang-specific playbooks below carry the concrete rules, code, and bad practices.
Language variants
| Backend | Playbook | Registry |
TypeScript — packages/api/typescript/ | typescript/SKILL.md | typescript/registry.yaml |
Go — packages/api/go/ | go/SKILL.md | go/registry.yaml |
How dispatch works
scripts/review.ts infers the language from the file extension (.ts / .go) and loads the matching <lang>/registry.yaml. The CLI scaffolder takes a --lang flag (--lang=typescript / --lang=go) or infers it from cwd. When editing or reviewing code, open the lang playbook matching the file you're touching — patterns and bad practices are coded per-language (e.g. VO-GO-01).

Does it work?
Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.
No reviews yet
People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.
- It worked
- Partly
- It didn't
Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.
Your trail
Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
Now do this for your own.
Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
