What it does

Sui Jsonrpc Skill is an agent skill from holon-run/uxc. Operate Sui public JSON-RPC through UXC with OpenRPC-driven discovery, mainnet fullnode defaults, and read-only query plus pubsub subscription guardrails.

Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including scripts and reference files (for example `agents/openai.yaml`, `references/usage-patterns.md` and `scripts/validate.sh`).

It sits in Backend & APIs, covering Event-driven systems, LLM guardrails and gRPC and Protobuf. The repository describes itself as: A unified CLI for discovering and invoking tools across OpenAPI, MCP, GraphQL, gRPC, and JSON-RPC. The licence is MIT.

When your agent uses it

  • Tasks that involve Event-driven systems
  • Tasks that involve LLM guardrails
  • Tasks that involve gRPC and Protobuf

Example prompts

  • “/sui-jsonrpc-skill”

Requirements

  • A Bash shell

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  1. Use the fixed link command by default
  2. Inspect operation schema first
  3. Prefer read/setup validation before any deeper query
  4. Execute with key/value or positional JSON
  5. Use uxc subscribe start directly for pubsub streams

What it can do on your machine

Read from SKILL.md and the folder at commit 562d47c. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 1 file in scripts/ (Shell), which the agent can run.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • fullnode.mainnet.sui.io

    Also links to:

    • docs.sui.io

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Sui Jsonrpc Skill loads about 1.1k tokens when it runs, and up to ~1.7k if it reads all its reference files. Until then it costs about 43 tokens; SKILL.md has 482 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~43
When it runs · the whole SKILL.md, loaded when a task matches
~1.1k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.7k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

Operate Sui public JSON-RPC through UXC with OpenRPC-driven discovery, mainnet fullnode defaults, and read-only query plus pubsub subscription guardrails.

Sui JSON-RPC Skill

Use this skill to run Sui JSON-RPC operations through uxc + JSON-RPC.

Reuse the uxc skill for shared execution and error-handling guidance.

Prerequisites

  • uxc is installed and available in PATH.
  • Network access to https://fullnode.mainnet.sui.io.
  • No API key is required for the public mainnet fullnode in this skill's default flow.

Scope

This skill covers a safe read-first Sui JSON-RPC surface:

  • chain identity and latest checkpoint reads
  • checkpoint lookup
  • object lookup
  • reference gas price reads
  • latest system state reads
  • pubsub subscriptions for events and transaction effects

This skill does not cover:

  • unsafe_* transaction-building methods
  • sui_executeTransactionBlock
  • wallet signing flows
  • custom/private Sui RPC providers with different auth or rate limits

Endpoint And Discovery

This skill targets the public Sui fullnode endpoint:

  • https://fullnode.mainnet.sui.io

For pubsub, use a Sui provider WebSocket endpoint that you have verified actually accepts JSON-RPC subscriptions. Do not assume the public HTTPS fullnode host automatically supports the same wss:// hostname for pubsub.

uxc JSON-RPC discovery depends on OpenRPC or rpc.discover. Sui exposes a discoverable method surface, so help-first flow works directly against the endpoint.

Authentication

The default public endpoint used by this skill does not require authentication.

If a user later points the same workflow at a private Sui RPC provider, verify its auth model first before reusing this skill unchanged.

Core Workflow

  1. Use the fixed link command by default:

    • command -v sui-jsonrpc-cli
    • If missing, create it: uxc link sui-jsonrpc-cli https://fullnode.mainnet.sui.io
    • sui-jsonrpc-cli -h

  2. Inspect operation schema first:

    • sui-jsonrpc-cli sui_getLatestCheckpointSequenceNumber -h
    • sui-jsonrpc-cli sui_getCheckpoint -h
    • sui-jsonrpc-cli sui_getObject -h

  3. Prefer read/setup validation before any deeper query:

    • sui-jsonrpc-cli sui_getChainIdentifier
    • sui-jsonrpc-cli sui_getLatestCheckpointSequenceNumber
    • sui-jsonrpc-cli suix_getReferenceGasPrice

  4. Execute with key/value or positional JSON:

    • key/value: sui-jsonrpc-cli sui_getCheckpoint id=254502592
    • positional JSON: sui-jsonrpc-cli sui_getObject '{"object_id":"0x6"}'

  5. Use uxc subscribe start directly for pubsub streams:

    • uxc subscribe start wss://<verified-sui-rpc-host> suix_subscribeEvent '{"params":[{"Package":"0x2"}]}' --sink file:$HOME/.uxc/subscriptions/sui-events.ndjson
    • uxc subscribe start wss://<verified-sui-rpc-host> suix_subscribeTransaction '{"params":[{"FromAddress":"0x..."}]}' --sink file:$HOME/.uxc/subscriptions/sui-transactions.ndjson
    • uxc subscribe status <job_id>
    • uxc subscribe stop <job_id>
Show full SKILL.md (171 more words)Show less
  • sui_getChainIdentifier
  • sui_getLatestCheckpointSequenceNumber
  • sui_getCheckpoint
  • sui_getObject
  • suix_getReferenceGasPrice
  • suix_getLatestSuiSystemState
  • suix_subscribeEvent
  • suix_subscribeTransaction

Guardrails

  • Keep automation on the JSON output envelope; do not use --text.
  • Parse stable fields first: ok, kind, protocol, data, error.
  • Stay on the public read-only method surface by default.
  • Do not call any unsafe_* methods through this skill without explicit follow-up design and review.
  • Do not use this skill for write/sign/submit flows; those need separate wallet/auth guidance.
  • Use uxc subscribe start for pubsub methods; the fixed sui-jsonrpc-cli link is for normal request/response methods.
  • Subscription jobs should always write to a sink file so events can be inspected and replayed safely.
  • Before documenting or automating a Sui pubsub host, confirm the specific provider actually exposes JSON-RPC WebSocket subscriptions; public HTTPS endpoints do not guarantee a matching wss:// endpoint.
  • Public RPC availability and rate limits can change over time; if discovery or execution starts failing, re-check the endpoint before assuming a uxc bug.
  • sui-jsonrpc-cli <operation> ... is equivalent to uxc https://fullnode.mainnet.sui.io <operation> ....
