First Dollar

A curriculum that teaches AI agents how to spend their own money.

What it does

Ten lessons, from "what is a wallet" to "your first real x402 purchase." Plus reference tools for troubleshooting and end-to-end testing. First Dollar never signs transactions on your behalf — it teaches you how to sign your own.

Principle

Teacher, not butler. First Dollar explains; the agent acts. The MCP never holds keys, never signs, never transacts. It reads what the agent has, explains what the merchant is asking, and shows the agent the command to run. The agent spends its own money with understanding.

Usage Guidance
This package appears to be an instructional tool and is internally consistent with that purpose, but take these precautions before installing or running it: 1) Inspect the package source (index.js) or the repository in npm before running 'npx firstdollar' to ensure there are no unexpected network calls or file operations you don't want. 2) Never paste private keys, seed phrases, or raw wallet files into prompts or supply them to the agent; the skill is designed to show commands, not to accept secrets. 3) When following suggested diagnostic commands, avoid running ones that print private keys or unencrypted wallet files; prefer checks that report presence/capabilities without revealing secrets. 4) Prefer installing in an isolated/test environment if you want to try test-payment flows and verify merchant endpoints (confirm the merchant URL yourself). 5) If you need higher assurance, fetch the package tarball from the registry and review the full index.js for any outbound network calls, telemetry, or unexpected behavior before running it. If you want, share the remainder of index.js and I can review the parts not included here for network activity or file I/O that would change this assessment.
Capability Analysis
Type: OpenClaw Skill Name: firstdollar Version: 1.0.4 The 'firstdollar' skill bundle is classified as suspicious because it provides tools that instruct the AI agent to search for and potentially expose sensitive cryptographic keys and wallet files within its environment. Specifically, the 'explain-my-wallet' tool in 'index.js' suggests commands like 'env | grep' for private keys and 'ls' for Solana/OpenClaw wallet files, which could lead to accidental credential leakage into the agent's conversation context. While the package's stated intent is educational (teaching agents to use the x402 protocol), the practice of prompting an agent to output its own secrets is a high-risk pattern that could be exploited for data exfiltration.

Capability Assessment
Purpose & Capability
The name/description (teaching agents about wallets and x402 payments) matches the declared tool set and package.json metadata. Required env vars, binaries, and config paths are nil, which is proportionate for an instructional/teaching MCP. The package.json dependency on @modelcontextprotocol/sdk is expected for an MCP server.
Instruction Scope
SKILL.md and the tool descriptions repeatedly emphasize that the skill will explain commands and checks but will not sign or hold keys. Several tools (e.g., explain-my-wallet, how-do-i-pay, verify-my-purchase, test-payment) return commands or explain checks the agent or user should run. That is coherent for a teaching tool, but these instructions could tell an agent or user to inspect local wallet files or run commands that, if executed carelessly, could expose private keys or secrets. The skill itself does not declare that it will read or exfiltrate files or env vars.
Install Mechanism
No explicit install spec in the registry besides an npx installation. Running 'npx firstdollar' will fetch the package from npm (or the npm registry mirror the user’s environment uses). This is a normal distribution channel but means code will be downloaded and executed at install/run time; users should verify package provenance before running npx.
Credentials
The skill declares no required env vars, no credentials, and no config paths. The curriculum is about inspecting and running commands against wallets the agent already controls; requesting no external secrets is proportionate. Note: the skill may instruct the user/agent to run commands that access wallet files or paste challenge data — these are expected for the stated purpose but sensitive.
Persistence & Privilege
The skill does not request always:true or any special persistent system privileges. It defines an MCP server entrypoint (index.js) as expected for an MCP bundle, and there is no evidence it modifies other skills or system-wide settings.
How to Use
  1. Make sure OpenClaw is installed (local or Docker)
  2. Run the install command in chat: /install firstdollar
  3. After installation, invoke the skill by name or use /firstdollar
  4. Provide required inputs per the skill's parameter spec and get structured output
