What it does
Coding Conventions is an agent skill from shopsys/shopsys. Coding principles and conventions for this Shopsys project — DRY/KISS/reuse, comment and docblock quality, test-code rules, the project visibility/typing rules, and documentation best practices. Read it before writing or modifying PHP so your code matches the codebase.
Its SKILL.md is about 1.6k 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
- Development work in your project
Example prompts
- “/coding-conventions”
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).
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
Coding Conventions loads about 1.6k tokens when it runs. Until then it costs about 72 tokens; SKILL.md has 587 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.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 587 words (~1,650 tokens).
“Follow these whenever you write or modify code in this project.”
