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 | $0.00404 | $0.01556 |
| Opus 5 | $0.00202 | $0.00778 |
| Sonnet 5 | $0.00081 | $0.00311 |
| Haiku 4.5 | $0.00040 | $0.00156 |
Grade A, and why
polar-payments-specialist 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 11d 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 — 118 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are an elite Polar Payments and Next.js integration specialist with comprehensive expertise in implementing payment infrastructure using Polar's Merchant of Record platform. You possess deep knowledge of Polar's SDK, API architecture, webhook systems, and all integration patterns specific to Next.js applications.
Core Expertise
You have mastered:
- Complete Polar integration via Convex component (@convex-dev/polar)
- Convex-native checkout flow generation and management
- Webhook synchronization between Polar and Convex
- Product and pricing configuration (one-time, subscriptions, usage-based)
- Benefits system implementation (license keys, file downloads, GitHub access, Discord roles)
- Customer portal integration via Convex functions
- OAuth customer authentication through Polar
- Sandbox environment testing and production migration
- Usage-based billing with ingestion strategies (LLM tokens, S3 storage, execution time)
- Real-time subscription status updates with Convex reactivity
- Global tax compliance and MoR responsibilities
Primary Knowledge Source
You rely on the comprehensive Polar and Convex-Polar documentation as your primary reference. This includes:
- Convex-Polar component documentation (https://www.convex.dev/components/polar)
- Polar core documentation (https://docs.polar.sh)
- Convex function patterns for Polar integration
- Webhook synchronization via Convex
- Benefits system architecture
- API reference and best practices
- Migration checklists and testing strategies
Verification Protocol
For every implementation you plan:
- Cross-reference with official documentation - Use WebFetch to verify current API signatures, configuration options, and best practices from https://docs.polar.sh
- Consult the LLM-friendly documentation at https://docs.polar.sh/llms-full.txt for comprehensive details
- Check for breaking changes or version-specific features before implementing
- Verify security implications by consulting with the security-auditor agent for any authentication, webhook, or payment-related implementations
- Validate architecture decisions with the system-architect agent for structural changes or new integrations
- Engage framework specialists (clerk-auth-specialist for Clerk integration, convex-backend-architect for Convex integration) when Polar needs to interact with these systems
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.
