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.

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 | $0.00042 | $0.01325 |
| Opus 5 | $0.00021 | $0.00662 |
| Sonnet 5 | $0.00008 | $0.00265 |
| Haiku 4.5 | $0.00004 | $0.00133 |
Grade A, and why
php-ecosystem-reference 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 — 114 lines — stays where its author put it; the contents beside it link to each section on GitHub.
It does not carry deep, version-specific how-to knowledge for Symfony full-stack, API Platform, or Slim — for implementation details it hands off to the research-expert agent and to [[php-http-psr]] for framework-agnostic HTTP.
Laravel is entirely out of scope — any Laravel task routes to the laravel-expert agent. Deep Symfony full-stack work has no dedicated expert in this ecosystem; this skill's job is to flag that gap explicitly to the user rather than improvise.
PHP Ecosystem Reference (Orientation)
Scope (read this first)
This skill is a routing / orientation map, NOT an implementation expert. It answers "which tool fits this problem, and where do I go next?" It does not carry deep, version-specific how-to knowledge for Symfony full-stack, API Platform, or Slim.
For actual implementation:
- Laravel → route to the
laravel-expertagent (out of scope here). - Framework-agnostic HTTP (PSR-7/15/17/18) → use [[php-http-psr]].
- Deep Symfony full-stack → there is no dedicated expert agent; flag this to the user (see boundaries.md).
Agent Workflow (MANDATORY)
Before relying on any detail here, use TeamCreate to spawn 2 agents:
- fuse-ai-pilot:research-expert - Verify current versions/APIs on symfony.com, api-platform.com, slimframework.com
- fuse-ai-pilot:explore-codebase - Detect which of these are already in composer.json
This skill orients; the research agent supplies verified specifics before any code.
Overview
| Area | What it is | Reference |
|---|---|---|
| Symfony Components | Decoupled PHP libraries, each installable standalone via Composer — no full framework needed | symfony-components.md |
| API Platform 4.3 | API-first framework built on Symfony (REST, GraphQL, OpenAPI from resource classes) | api-platform.md |
| Slim 4.15 | PSR-7/PSR-15 micro-framework for small APIs and services | slim-framework.md |
| Boundaries | Where this skill stops and who to route to | boundaries.md |
What ships with it
5 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-ecosystem-reference is a skill published in the GitHub repository fusengine/agents (25 stars, last pushed 1mo ago), licensed MIT. It adds 42 tokens to every session and 1,325 once invoked, about $0.0002 per session on Opus 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.
