Token cost

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.

Security

Grade A, and why

sui-sdks 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 8d 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.

Sui SDKs

MCP tool: When available in your environment, also query the Sui documentation MCP server (https://sui.mcp.kapa.ai) for up-to-date answers. Use it for verification and for details not covered by these reference files.

Most AI agents give confusing, outdated, or cross-wired answers about Sui SDKs. This skill fixes the three most common failure modes:

  1. Recommending a community SDK as if it were official. Only two SDKs are maintained by Mysten Labs: TypeScript (@mysten/sui) and Rust (sui-rust-sdk family of crates). Everything else is community-maintained.
  2. Mixing up TypeScript SDK generations. The old @mysten/sui.js package was renamed to @mysten/sui at v1.0. The v2 client API (client.core.*, include instead of show*, SuiGrpcClient replacing SuiClient) is distinct from v1.
  3. Not using the installed LLM docs. Every @mysten/* package ships docs/llms-index.md + topic-specific markdown files to node_modules. Agents should read those before answering; they are guaranteed to match the installed version.

All patterns in this skill are derived from:

If unsure about any specific API in any SDK, fetch from the relevant doc page — do not extrapolate from a different SDK's surface.

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.
