sui-platform

Rules for building on Sui, a blockchain platform, including address balances and gasless stablecoin transfers.

In plain words
What is it for?
Use it when designing payment systems, choosing a transaction payer, sending stablecoins, or debugging Sui transaction failures.
Why use it?
It explains limits and eligibility details that can otherwise cause transaction conflicts or misleading balance errors.

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.

Made for: Cursor.

Per session 0 Nothing until a file matches its globs; then the whole rule loads.
When invoked 365 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
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-platform 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 2d 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.

What it actually says

Sui Platform → .claude/skills/t2000-sui-platform/SKILL.md

The two things people get wrong:

  1. "One Sui address can only do one tx at a time" is a myth for a server payer. Address Balances (SIP-58) turn fungible holdings into an accumulator (no owned-object lock) and address-balance gas removes the gas-coin contention → a single settlement address scales. A wallet fleet is a blast-radius lever, never a scaling prerequisite.
  2. "Gasless" is narrower than it sounds. Only pure stablecoin transfers on the allowlisted trio qualify — any custom Move call still needs gas. Plus: 0.01 minimum, a dust-remainder floor that surfaces as a misleading "insufficient SUI balance" error, and auto-detect that only works on gRPC/GraphQL transports.

Read the full gotcha list before architecting a payer or debugging a send: .claude/skills/t2000-sui-platform/SKILL.md.

Changes

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.

sui-platform is a cursor rule published in the GitHub repository mission69b/t2000 (23 stars, last pushed 3d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 365 tokens. 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.
