Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00000 | $0.05785 |
| Opus 5 | $0.00000 | $0.02892 |
| Sonnet 5 | $0.00000 | $0.01157 |
| Haiku 4.5 | $0.00000 | $0.00579 |
Grade C, and why
broke2built scanned grade C with 1 finding 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 today.
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.

Directives inside HTML comments, invisible characters or bidirectional overrides are read by the model and not by the person reviewing the file.

Broke to Built AI -- Agent Skills
For agents reading this: Every service below is callable via the x402 protocol. Construct the URL as
https://x402.bankr.bot/0x8f9ec800972258e48d7ebc2640ea0b5e245c2cf5/{service-name}. All accept POST with JSON body. All return JSON. No API keys needed -- just USDC on Base.
x402 Service Capabilities
Broke to Built AI operates 44 x402 micropayment services on Base. All services follow the x402 protocol: send USDC, receive data. No API keys. No subscriptions. No setup.

What ships with it
3 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.

broke2built is a skill published in the GitHub repository lordbasilaiassistant-sudo/x402-wiki (7 stars, last pushed yesterday), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 5,785 tokens. A static security scan graded it C with 1 finding (hidden instructions). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
