phantom-connect-sdk: Skill for Claude Code

.claude/skills/new-cli-action/SKILL.md

new-cli-action is a skill for Claude Code from phantom/phantom-connect-sdk. It costs 64 tokens per session (2,922 once invoked), scanned A, original, MIT.

A guide for adding a new command or tool to the Phantom CLI, a command-line interface for running actions. The action is also registered for the project’s MCP server and OpenClaw system.

In plain words
What is it for?
Use it to scaffold a new Phantom CLI command, including its inputs, result, command group, and registry entries.
Why use it?
It provides the required file creation and registration steps so one action is available in all three supported interfaces.

Skill for Claude Code

Written for Claude Code: allowed-tools in frontmatter. Also seen: mentions Claude Code; built for openclaw.

This is phantom/phantom-connect-sdk's own configuration. It tells Claude Code how to work on phantom-connect-sdk itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything phantom-connect-sdk configures →

Needs its repository: it reads a path above its own folder, which exists only inside the repository. The line is import { createAction } from "../utils/actions.js";.

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

new-cli-action 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.

/new-cli-action — Scaffold a New CLI Action

Arguments passed: $ARGUMENTS

You are helping the user add a new command to the Phantom CLI (packages/cli). Every action is automatically exposed in three places: the CLI binary, the MCP server, and OpenClaw. All three come for free from a single createAction call — the user only needs to write one file and make two registration edits.

Framework: The CLI is built on incur, a TypeScript framework for building CLIs that work as both binaries and MCP servers. The Cli and z imports in every action file come from incur. If you need deeper guidance on incur patterns — schemas, Cli APIs, or advanced usage — run npx incur skills add in the project root to pull the official incur skill into Claude Code and piggyback off it.

Step 1 — Understand the requirement

If $ARGUMENTS is empty or vague, ask the user:

  1. What should the command do? (one sentence)
  2. What inputs does it need?
  3. What does a success response look like?
  4. Where should it live in the CLI? (top-level like phantom buy, or under a sub-group like phantom perps open)

If $ARGUMENTS describes the command well enough, proceed directly.

Step 2 — Determine the file location and CLI group

The CLI is structured as follows. Read packages/cli/src/index.ts and the relevant command file to confirm the current shape before writing anything.

CLI path Command file Action files
phantom <cmd> src/index.ts (registered directly) src/actions/<name>.ts
phantom wallet <cmd> src/commands/wallet.ts src/actions/<name>.ts
phantom solana <cmd> src/commands/solana.ts src/actions/<name>.ts
phantom evm <cmd> src/commands/evm.ts src/actions/<name>.ts
phantom perps <cmd> src/commands/perps.ts src/actions/<name>.ts
phantom token <cmd> src/commands/token.ts src/actions/<name>.ts

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.
