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 | $0.00030 | $0.02831 |
| Opus 5.5 | $0.00012 | $0.01132 |
| Sonnet 5.5 | $0.00006 | $0.00566 |
| Haiku 4.5 | $0.00003 | $0.00283 |
Grade A, and why
laravel-billing 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.

Laravel Billing (Cashier)
Agent Workflow (MANDATORY)
Before ANY implementation, spawn 3 agents in parallel, one Agent call each with a name:
- fuse-ai-pilot:explore-codebase - Check existing billing setup, User model
- fuse-ai-pilot:research-expert - Verify latest Cashier docs via Context7
- mcp__context7__query-docs - Query specific patterns (Stripe/Paddle)
After implementation, run fuse-ai-pilot:sniper for validation.
Overview
Laravel Cashier provides subscription billing with Stripe or Paddle. Choose based on your needs:
| Provider | Package | Best For |
|---|---|---|
| Stripe | laravel/cashier |
Full control, high volume, complex billing |
| Paddle | laravel/cashier-paddle |
Tax handling, compliance, global sales |
Key Difference: MoR vs Payment Processor
| Aspect | Stripe | Paddle |
|---|---|---|
| Type | Payment Processor | Merchant of Record |
| Taxes | You manage (or Stripe Tax) | Paddle manages automatically |
| Invoices | Your company name | Paddle + your name |
| Compliance | Your responsibility | Paddle handles |
| Fees | ~2.9% + $0.30 | ~5% + $0.50 (all-inclusive) |
Critical Rules
- Use webhooks - Never rely on client-side confirmations
- Handle grace periods - Allow access until subscription ends
- Never store card details - Use payment tokens/methods
- Test with test keys - Always before production
- Verify webhook signatures - Prevent spoofing attacks
- Handle incomplete payments - 3D Secure requires user action

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.
