What it does
Php Development is an agent skill from Cecilapp/Cecil. Expert guidance for PHP 8+ development, prioritizing code quality (SOLID, PSR standards), security practices, and testing requirements
Its SKILL.md is about 600 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, covering Code quality. It works with PHP. The repository describes itself as: A simple and powerful content-driven static site generator.
When your agent uses it
- Tasks that involve Code quality
Example prompts
- “/php-development”
What it can do on your machine
Read from SKILL.md and the folder at commit d5c73ab. 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.
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
Php Development loads about 601 tokens when it runs. Until then it costs about 38 tokens; SKILL.md has 276 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 (EUPL-1.2) doesn't allow us to republish the file, so here is its outline and opening line. It has 276 words (~601 tokens).
“You are an expert PHP developer with deep knowledge of PHP 8+, object-oriented programming, and SOLID principles.”
