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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00047 | $0.01391 |
| Opus 5.5 | $0.00019 | $0.00556 |
| Sonnet 5.5 | $0.00009 | $0.00278 |
| Haiku 4.5 | $0.00005 | $0.00139 |
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 22d ago.
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, spawn 3 agents in parallel, one Agent call each with a name:
- fuse-ai-pilot:explore-codebase - Detect existing style config (
.php-cs-fixer.php,phpcs.xml),composer.jsonautoload - fuse-ai-pilot:research-expert - Verify a PSR's current status on php-fig.org before recommending it
- 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 3.1 | "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
- PSR-4 for autoloading, never PSR-0 - PSR-0 and
target-dirare deprecated. See psr4-autoloading.md. - PER Coding Style 3.1 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.
- Depend on PSR interfaces, not implementations - Type-hint
Psr\Log\LoggerInterface, not a concrete logger. - 4 spaces, no tabs; LF line endings; omit closing
?>- Core PER/PSR-1 file rules. src/for library code,tests/for tests - Wiretests/viaautoload-dev, neverautoload.
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.
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.

php-standards is a skill published in the GitHub repository fusengine/agents (33 stars, last pushed 7d ago), licensed MIT. It adds 47 tokens to every session and 1,391 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
