At a glance

Create a Shopsys-style enum (a class extending AbstractEnum with public typed constants, NOT a native PHP enum).

  • You need to define a fixed set of values that downstream projects (like project-base) might extend
  • SKILL.md covers The pattern, Where the enum file goes, How AbstractEnum works and Using the enum at call sites, plus 4 more sections
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Create Enum is an agent skill from shopsys/shopsys. Create a Shopsys-style enum (a class extending AbstractEnum with public typed constants, NOT a native PHP enum). Use when you need to define a fixed set of values that downstream projects (like project-base) might extend or restrict.

Its SKILL.md is about 1.9k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Development. It works with PHP. The repository describes itself as: Main repository for maintaining Shopsys Platform packages. Open for ISSUES and PULL REQUESTS.

When your agent uses it

  • You need to define a fixed set of values that downstream projects (like project-base) might extend

Example prompts

  • “/create-enum”

What it can do on your machine

Read from SKILL.md and the folder at commit 494a8a6. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are php and yaml).

    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

Create Enum loads about 1.9k tokens when it runs. Until then it costs about 61 tokens; SKILL.md has 632 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~61
When it runs · the whole SKILL.md, loaded when a task matches
~1.9k

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.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 632 words (~1,922 tokens).

“Native PHP enums (enum Foo: string { case BAR = 'bar'; }) are implicitly final and cannot be extended. Downstream Shopsys projects (notably project-base) routinely extend framework classes to add domain-specific cases or hide unused ones, so the project uses…”
