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 | $0.00112 | $0.01292 |
| Opus 5 | $0.00056 | $0.00646 |
| Sonnet 5 | $0.00022 | $0.00258 |
| Haiku 4.5 | $0.00011 | $0.00129 |
Grade A, and why
open-source-strategy 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 7d 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.

Strategies: Open Source
Guides open source as a commercialization path: build community and trust first, monetize later. Many products use open source for early growth (Cursor from VSCode, Llama, Qwen, Dify) and later commercialize via managed services or open core. For GitHub (SEO, GEO, README, Awesome lists), see github. For directory submission (DevHunt, Awesome lists), see directory-submission.
When invoking: On first use, if helpful, open with 1–2 sentences on what this skill covers and why it matters, then provide the main output. On subsequent use or when the user asks to skip, go directly to the main output.
Definition & Why
Open source strategy = Use open source for distribution, trust, and community; monetize through enterprise features, managed services, or support. 95% of enterprises use open source; 33% increasing usage. Community becomes your marketing force—users self-host, contribute, and recommend.
| Path | Example |
|---|---|
| Open source → Commercial product | Cursor (VSCode fork); Llama, Qwen (enterprise/cloud) |
| Open core → Managed service | Dify (self-host free + cloud paid); MongoDB Atlas; Confluent |
Core insight: Brand is the moat when code is commoditized. Developers won't pay directly; they become your marketing army through word-of-mouth, content, and recommendations.
Business Models
| Model | Description | Examples |
|---|---|---|
| Open Core | Core free; enterprise features (SSO, audit, multi-tenancy) paid | GitLab, Elastic, Grafana |
| Managed Services (SaaS) | Self-host free; cloud/hosted paid | MongoDB Atlas, Confluent, Dify |
| Support-First | Free software; enterprise support subscriptions | Red Hat |
| Free + Paid Convenience | 70–80% revenue from cloud; self-host free | Most COSS companies |
Monetization layer: Enterprise users buy risk mitigation—SLAs, indemnification, security patches, support—not just code.
Developer-First Distribution
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.
