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 | $0.00052 | $0.01650 |
| Opus 5.5 | $0.00021 | $0.00660 |
| Sonnet 5.5 | $0.00010 | $0.00330 |
| Haiku 4.5 | $0.00005 | $0.00165 |
Grade A, and why
php-http-psr 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 1mo 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 — 146 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Includes guidance on reference implementations (nyholm/psr7, guzzlehttp/psr7, laminas-diactoros) and how to choose between them, plus a complete middleware-pipeline template.
Do NOT use this skill for Laravel's own HTTP layer (route to laravel-expert instead) or for Symfony's HttpFoundation component, which is a different, non-PSR-7 HTTP model — bridge the two via symfony/psr-http-message-bridge when needed (see references/implementations.md).
PHP HTTP — PSR-7 / 15 / 17 / 18
Agent Workflow (MANDATORY)
Before ANY implementation, spawn 3 agents in parallel, one Agent call each with a name:
- fuse-ai-pilot:explore-codebase - Detect the PSR-7 implementation already in use (composer.json)
- fuse-ai-pilot:research-expert - Verify current interface versions on php-fig.org + Packagist
- mcp__context7__query-docs - Check the chosen implementation's factory API
After implementation, run fuse-ai-pilot:sniper for validation.
Overview
These four PSR standards let libraries handle HTTP without coupling to any framework. Code depends on interfaces (Psr\Http\*); a concrete implementation is injected.
| Standard | Package | Provides |
|---|---|---|
| PSR-7 | psr/http-message |
Immutable HTTP messages: MessageInterface, RequestInterface, ResponseInterface, ServerRequestInterface, StreamInterface, UriInterface, UploadedFileInterface |
| PSR-15 | psr/http-server-handler + psr/http-server-middleware |
RequestHandlerInterface, MiddlewareInterface — the middleware pipeline |
| PSR-17 | psr/http-factory |
Factories that create PSR-7 objects without naming a concrete class |
| PSR-18 | psr/http-client |
ClientInterface::sendRequest() — send a PSR-7 request, get a PSR-7 response |
What ships with it
7 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-http-psr is a skill published in the GitHub repository fusengine/agents (33 stars, last pushed 7d ago), licensed MIT. It adds 52 tokens to every session and 1,650 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.
