What is api-platform-resources?

A guide for defining API Platform resources, the public endpoints and data models exposed by a Symfony API.

Use it to configure REST or GraphQL resources, operations, pagination, typed OpenAPI documentation, DTOs, providers, processors, validation, and security.

It keeps operations, pagination, and API documentation explicit and consistent as the API evolves.

api-platform-resources — Skill for Claude Code by dev-toolings

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Any agent

npx skills add dev-toolings/superpowers-symfony --skill api-platform-resources

Clone the repo

git clone --depth 1 https://github.com/dev-toolings/superpowers-symfony

Made for: Claude Code.

Or install superpowers-symfony, the plugin that ships this one along with the rest of its 44 skills, 13 commands, 7 agents, 1 hook.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00043	$0.00528
Opus 5.5	$0.00017	$0.00211
Sonnet 5.5	$0.00009	$0.00106

Security

Grade A, and why

api-platform-resources scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 17d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

91% identical to api-platform-dto-resources — 39 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

Api Platform Resources (Symfony)

Use when

Exposing a new entity or class as an #[ApiResource].
Choosing exactly which of Get, GetCollection, Post, Put, Patch, and Delete the API offers.
Tuning collection pagination (items per page, partial pagination, client control).
Documenting operations with typed OpenAPI objects instead of openapiContext arrays.

Default workflow

Install only the components you need: api-platform/symfony, api-platform/doctrine-orm, and optionally api-platform/graphql; on Symfony 6.4 LTS, pin them to ~4.3.0.
List every operation in operations:, since declaring any one stops the automatic CRUD, and Put is never automatic.
Set uriTemplate, requirements, status, or routePrefix only where the defaults do not fit.
Configure pagination through resource attributes or api_platform.defaults in config/packages/api_platform.yaml.
Describe operations with openapi: model objects, set validationContext groups, then check the routes and the OpenAPI export.

Guardrails

Declaring one operation removes the default CRUD: an operations: [new Get()] resource has no collection, Post, or Delete.
openapiContext arrays are deprecated in v4: use the typed openapi: option.
collectionOperations and itemOperations no longer exist.
paginationClientEnabled lets clients disable pagination: keep paginationMaximumItemsPerPage set.

Progressive disclosure

Use this file for execution posture and risk controls.
Open references when deep implementation details are needed.

Output contract

The resource class with its explicit operation list and the routes it produces.
Pagination and OpenAPI settings, with the reason for each override.
Route listing and test results for each declared operation.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
