What it does
Value Objects And Dtos is an agent skill from dev-toolings/superpowers-symfony. Design Value Objects for domain concepts and DTOs for data transfer with proper immutability (readonly) and validation
Its SKILL.md is about 390 tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `reference.md`).
The repository describes itself as: Claude Code plugin for Symfony 7.4 LTS & 8.x — 44 skills, 7 AI subagents & 13 commands for API Platform v4, Doctrine ORM 3, TDD (Pest/PHPUnit), Messenger, security & DDD. The licence is MIT.
Example prompts
- “/value-objects-and-dtos”
Requirements
- Pre-approved tools (allowed-tools): Read, Glob, Grep
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- Decide: a value object for a domain concept with invariants, a DTO for data crossing a boundary.
- Make it readonly, validate in the constructor, and fail fast.
- Give value objects equality by value and operations that return new instances.
- Persist value objects as Doctrine embeddables.
- Keep input DTOs (validation constraints) apart from output DTOs (serializer attributes).
What it can do on your machine
Read from SKILL.md and the folder at commit 459bcd0. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
ReadGlobGrep
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
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
Value Objects And Dtos loads about 394 tokens when it runs. Until then it costs about 35 tokens; SKILL.md has 189 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.

Value Objects And Dtos (Symfony)
Use when
- A domain concept with rules of its own (money, email, address) travels as raw scalars.
- Data crosses a boundary: request input, API output, message payload.
- Storing a value object inside a Doctrine entity.
Default workflow
- Decide: a value object for a domain concept with invariants, a DTO for data crossing a boundary.
- Make it
readonly, validate in the constructor, and fail fast. - Give value objects equality by value and operations that return new instances.
- Persist value objects as Doctrine embeddables.
- Keep input DTOs (validation constraints) apart from output DTOs (serializer attributes).
Guardrails
- No setters and no mutation: a change returns a new instance.
- DTOs carry data only, with no behavior.
- Never expose entities directly as API input or output.
- Store money as an integer in minor units, never as a float.
Progressive disclosure
- Use this file for execution posture and risk controls.
- Open references when deep implementation details are needed.
Output contract
- Value objects with their invariants and equality.
- Input and output DTOs, and their mapping to and from entities.
- Unit tests for each invariant.
