At a glance

Write PHP following PSR coding standards, SOLID principles, and code-quality guidelines.

  • Guard clauses—not Composer/PSR-4 project configuration
  • SKILL.md covers Priority: P1 (HIGH), Structure, Implementation Guidelines and Anti-Patterns, plus 2 more sections
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
  • Tasks that involve Code quality

What it does

Php Best Practices is an agent skill from HoangNguyen0403/agent-skills-standard. Write PHP following PSR coding standards, SOLID principles, and code-quality guidelines. Use for PHP style, design, refactoring, naming, and guard clauses—not Composer/PSR-4 project configuration.

Its SKILL.md is about 640 tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files (for example `evals/evals.json` and `references/implementation.md`).

It sits in Development, covering Code quality, Design patterns and Refactoring. It works with PHP. The repository describes itself as: A collection of Agent Skills Standard and Best Practice for Programming Languages, Frameworks that help our AI Agent follow best practies on frameworks and programming laguages. The licence is MIT.

When your agent uses it

  • Guard clauses—not Composer/PSR-4 project configuration
  • Tasks that involve Code quality
  • Tasks that involve Design patterns

Example prompts

  • “/php-best-practices”

What it can do on your machine

Read from SKILL.md and the folder at commit b529c2d. 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 Best Practices loads about 638 tokens when it runs, and up to ~801 if it reads all its reference files. Until then it costs about 54 tokens; SKILL.md has 239 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~54
When it runs · the whole SKILL.md, loaded when a task matches
~638
With references · SKILL.md plus every file in references/, read only if the agent opens them
~801

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.

Implementation Guidelines

Coding Style (PSR Standards)
  • PSR-12: Enforce 4-space indentation and opening braces on same line for functions/methods.
  • Organization: One class per file; use statements follow namespace. Run PHP CS Fixer with PSR-12 preset.
  • Naming Conventions: Use PascalCase (UserService) for classes, camelCase (getUserById) for methods/variables, and SNAKE_CASE (MAX_RETRIES) for class constants.
SOLID Principles in PHP
  • SRP: Single Responsibility Principle — extract each into its own focused class; keep classes under ~200 lines.
  • Dependency Inversion: inject via constructor with interface type-hints. Inject dependencies via constructor for testability. Favor composition over deep inheritance chains.
  • Separation of Concerns: Use Interfaces for decoupling integrations and logic.
Logic & Performance
  • Guard Clauses: Return early for error conditions (e.g., if (!$user) return null); no else after return to reduce nesting depth.
  • Traits: Define trait HasTimestamps (e.g., use HasTimestamps) for cross-cutting behavior. Keep traits focused and lightweight.
  • Helper Functions: Avoid global-namespace logic; organize in classes.

Anti-Patterns

  • No monolithic classes: Each class one responsibility (SRP).
  • No hardcoded magic numbers: Define as named class constants.
  • No deep nesting: Use guard clauses to return early.
  • No echo in services: Return data; let controller output.
