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 5.1 | $0.00015 | $0.00251 |
| Opus 5 | $0.00008 | $0.00125 |
| Sonnet 5 | $0.00003 | $0.00050 |
| Haiku 4.5 | $0.00002 | $0.00025 |
Grade A, and why
symfony 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 6d 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.
What it actually says
Symfony
Symfony v7.1 (2025) is the bedrock of modern PHP (Drupal, Laravel components). It emphasizes Attributes (Annotations) and strict typing.
When to Use
- Enterprise PHP: Complex business logic, long-term stability (LTS).
- Components: Using standalone libraries (Console, HttpFoundation) in other apps.
- DDD: Well-suited for complex domain modeling.
Core Concepts
Dependency Injection
The Container is central. Auto-wiring is default.
Bundles
Plugin system.
Attributes
#[Route('/api', name: 'api')] replaces YAML/Annotation configs.
Best Practices (2025)
Do:
- Use Maker Bundle:
php bin/console make:controller. - Use AssetMapper: No Webpack/Node.js required for simple assets.
- Use Messenger: For async message bus (queues).
Don't:
- Don't use YAML for Services: Use PHP attributes and autowiring.

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.

symfony is a skill published in the GitHub repository G1Joshi/Agent-Skills (12 stars, last pushed 7mo ago), licensed MIT. It adds 15 tokens to every session and 251 once invoked, about $0.0001 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.
