What it does
API Platform Versioning is an agent skill from dev-toolings/superpowers-symfony. Evolve API Platform APIs via deprecation (deprecationReason/sunset, RFC 8594/9745), the recommended alternative to versioning; plus path/header strategies
Its SKILL.md is about 530 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
- “/api-platform-versioning”
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.
- Try deprecation first: set deprecationReason on the resource, the operation, or #[ApiProperty].
- Add sunset: with a date, and on v4 add headers carrying Deprecation (RFC 9745) and a Link with rel="successor-version".
- Before v4, emit those headers from a KernelEvents::RESPONSE listener.
- Only if still breaking, expose parallel uriTemplate values (/v1, /v2) with distinct groups, or output DTOs with one provider per version.
- Mark the old operation as deprecated in OpenAPI, document the changes per version, and test every active version.
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 Versioning loads about 528 tokens when it runs. Until then it costs about 45 tokens; SKILL.md has 246 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: notes
The automated check noted patterns worth knowing about, such as sudo or a known installer.
- NotePre-approves every shell command (allowed-tools: Bash)SKILL.md
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 Versioning (Symfony)
Use when
- A field, operation, or resource is being renamed or removed and consumers need time to migrate.
- Announcing a removal date to clients with
SunsetandDeprecationheaders. - Deciding between deprecation and parallel
/v1and/v2surfaces. - A breaking representation change that deprecation and groups cannot express.
Default workflow
- Try deprecation first: set
deprecationReasonon the resource, the operation, or#[ApiProperty]. - Add
sunset:with a date, and on v4 addheaderscarryingDeprecation(RFC 9745) and aLinkwithrel="successor-version". - Before v4, emit those headers from a
KernelEvents::RESPONSElistener. - Only if still breaking, expose parallel
uriTemplatevalues (/v1,/v2) with distinct groups, or output DTOs with one provider per version. - Mark the old operation as deprecated in OpenAPI, document the changes per version, and test every active version.
Guardrails
- Prefer deprecation: path versioning is the fallback, not the default.
- Always set a sunset date and keep at most 2 or 3 versions active.
deprecationReasonandsunsetare stable across v3 and v4, but the RFC 9745headersoption is v4-era: verify it on your installed version.- Use groups for minor additive changes rather than a new version.
Progressive disclosure
- Use this file for execution posture and risk controls.
- Open references when deep implementation details are needed.
Output contract
- The deprecation or versioning strategy chosen and why.
- Deprecated elements with their sunset dates and successor links.
- Tests for each active version and for the headers.
