What it does
API Platform Dto Resources is an agent skill from dev-toolings/superpowers-symfony. Map entities to API DTOs in API Platform (v5, 4.4, 4.3) with the Symfony Object Mapper ([Map], stateOptions) for decoupled input/output contracts
Its SKILL.md is about 590 tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `reference.md`).
It works with Symfony. 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
- “/api-platform-dto-resources”
Requirements
- Pre-approved tools (allowed-tools): Read, Glob, Grep, Write, Edit, Bash
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- Require symfony/object-mapper and set stateOptions: new Options(entityClass: ...) on the DTO resource.
- Bind the DTO and the entity with #[Map(source: ...)] and #[Map(target: ...)], and use #[Map(transform: ...)] for computed fields.
- For distinct shapes, create input and output classes and wire them with input: and output: on each operation.
- When mapping needs real logic, write a custom ProcessorInterface that calls ObjectMapperInterface::map().
- Test each operation: payload in, response shape out.
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:
ReadGlobGrepWriteEditBash
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
API Platform Dto Resources loads about 593 tokens when it runs. Until then it costs about 43 tokens; SKILL.md has 267 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

The automated check noted patterns worth knowing about, such as sudo or a known installer.

allowed-tools: Read, Glob, Grep, Write, Edit, Bash
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.

Api Platform Dto Resources (Symfony)
Use when
- The
#[ApiResource]class must be the API contract, decoupled from the Doctrine entity. - Entity and API fields differ in name or format (rename, formatted price, computed value).
- Create, update, or list operations need their own input or output shape.
- Migrating code that relied on
DataTransformerInterface, which no longer exists.
Default workflow
- Require
symfony/object-mapperand setstateOptions: new Options(entityClass: ...)on the DTO resource. - Bind the DTO and the entity with
#[Map(source: ...)]and#[Map(target: ...)], and use#[Map(transform: ...)]for computed fields. - For distinct shapes, create input and output classes and wire them with
input:andoutput:on each operation. - When mapping needs real logic, write a custom
ProcessorInterfacethat callsObjectMapperInterface::map(). - Test each operation: payload in, response shape out.
Guardrails
- The automatic Object Mapper provider and processor only apply when
stateOptionshas anentityClassand both the DTO and the entity carry#[Map]. DataTransformerInterfaceis gone: use Object Mapper or a provider and processor.- No Object Mapper on 3.4 or on Symfony 6.4 LTS (it needs Symfony 7.3+): map manually in a
ProviderInterfaceand aProcessorInterface. ObjectMapperProcessoris removed in 5.0: the automatic path usesObjectMapperInputProcessorandObjectMapperOutputProcessor(4.3+).- Never return the entity itself from a DTO resource: only mapped fields reach the client.
Progressive disclosure
- Use this file for execution posture and risk controls.
- Open references when deep implementation details are needed.
Output contract
- The resource, input, and output classes with their
#[Map]bindings. - The mapping path chosen (Object Mapper or custom processor) and why.
- Tests showing the request and response shape of each operation.
