php-standards

php-standards is a skill for Claude Code, Codex from fusengine/agents. It costs 47 tokens per session (1,362 once invoked), scanned A, original, MIT.

A PHP development guide covering Composer package setup, automatic class loading, code style, and PSR interfaces—shared conventions for PHP libraries and applications.

In plain words
What is it for?
Use it to configure composer.json, map namespaces with PSR-4, organise source and test files, and apply PHP coding-style and interface standards.
Why use it?
It helps keep project structure and coding conventions consistent, so PHP code is easier for tools and other developers to use.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

php-standards scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 108 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Includes composer.json and project-structure templates (src/ for library code, tests/ wired via autoload-dev, PSR-4 namespace mapping), and the core PER/PSR-1 file rules (4 spaces, LF endings, no closing ?>).

Do NOT use this skill for language syntax or feature questions — that is php-language-modern. Do NOT use it for Laravel-specific conventions, which live in the Laravel plugin.

PHP Standards (PSR / PER / Composer)

Agent Workflow (MANDATORY)

Before applying a standard, use TeamCreate to spawn 3 agents:

  1. fuse-ai-pilot:explore-codebase - Detect existing style config (.php-cs-fixer.php, phpcs.xml), composer.json autoload
  2. fuse-ai-pilot:research-expert - Verify a PSR's current status on php-fig.org before recommending it
  3. mcp__context7__query-docs - Cross-check composer.json schema

After changes, run fuse-ai-pilot:sniper for validation.


Overview

Concern Standard Notes
Autoloading PSR-4 Recommended; PSR-0 is deprecated
Coding style PER Coding Style 3.0 "Extends, expands and replaces PSR-12"; PSR-12 remains the Accepted PSR
Logging PSR-3 LoggerInterface
Caching PSR-6 / PSR-16 Pool vs Simple Cache
HTTP PSR-7 / 15 / 17 / 18 Message / Handlers / Factories / Client
DI container PSR-11 ContainerInterface
Events PSR-14 Event Dispatcher
Time PSR-20 ClockInterface — testable "now"

Critical Rules

  1. PSR-4 for autoloading, never PSR-0 - PSR-0 and target-dir are deprecated. See psr4-autoloading.md.
  2. PER Coding Style 3.0 is the current style spec - It supersedes PSR-12 in practice while requiring PSR-1. PSR-12 is still the officially Accepted PSR — document the nuance, don't pretend PSR-12 was withdrawn. See per-coding-style.md.
  3. Depend on PSR interfaces, not implementations - Type-hint Psr\Log\LoggerInterface, not a concrete logger.
  4. 4 spaces, no tabs; LF line endings; omit closing ?> - Core PER/PSR-1 file rules.
  5. src/ for library code, tests/ for tests - Wire tests/ via autoload-dev, never autoload.

What ships with it

6 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
