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 | $0.00198 | $0.02229 |
| Opus 5.5 | $0.00079 | $0.00892 |
| Sonnet 5.5 | $0.00040 | $0.00446 |
| Haiku 4.5 | $0.00020 | $0.00223 |
Grade A, and why
cross-chain 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 1mo 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 — 64 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Cross-Chain on Stellar
Stellar connects to other blockchains over several production rails, each built for a different job. Picking the wrong rail wastes engineering effort; picking the right one is a routing decision, not a research project. This file routes; the deep dives live alongside it — read the file that matches the task:
| You want to | Use | Where |
|---|---|---|
| Move native USDC between Stellar and an EVM chain or Solana (no wrapped assets, no liquidity pools) | Circle CCTP V2 | cctp.md |
| Move native USDT between Stellar and an EVM chain | USDT0, a LayerZero OFT | layerzero.md |
| Have a Stellar contract call a contract on another chain, or receive calls from one (arbitrary payloads) | Axelar GMP or LayerZero OApp | axelar.md, layerzero.md |
| Make a token — new or an existing Stellar asset — exist on multiple chains | Axelar ITS or LayerZero OFT | axelar.md, layerzero.md |
| Swap any asset cross-chain (BTC, ETH, SOL, … → XLM or Stellar USDC) without integrating a bridge yourself | NEAR Intents | below |
Rules of thumb: if the asset is USDC and both ends are CCTP chains, CCTP is the cheapest and most direct (it burns and mints Circle-native USDC — nothing wrapped, nothing pooled). If the asset is USDT, the answer is USDT0 over LayerZero OFT — a different rail, and one whose shape changes per leg: Stellar burns and mints, while the Ethereum leg locks and unlocks canonical USDT through an OFT Adapter, so check the route's OFT mode before you describe the flow. If you need logic, not just value, on the far chain, that is message passing — two rails do it, and the comparison at the end of layerzero.md helps you pick between Axelar's shared validator security and LayerZero's app-configured DVN sets. If you control a token and want it multichain, that is ITS or OFT on the same split. If the user just wants "turn my X on chain A into Y on Stellar" and you don't want bridge plumbing at all, quote it through NEAR Intents.
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.

cross-chain is a skill published in the GitHub repository stellar/stellar-dev-skill (54 stars, last pushed 3d ago), licensed Apache-2.0. It adds 198 tokens to every session and 2,229 once invoked, about $0.0008 per session on Opus 5.5. 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 2026-08-30.
