What Are Agent Skills
Agent Skills are structured instruction packages (SKILL.md files) that teach AI coding assistants how to use ChainStream’s on-chain data and DeFi capabilities. Unlike raw API docs, skills provide decision trees, workflows, safety rules, and error recovery — everything an AI agent needs to operate autonomously.
chainstream-data
Tool pattern — read-only on-chain data: token analytics, market trends, wallet profiling, WebSocket streams
chainstream-defi
Process pattern — irreversible DeFi execution: swap, bridge, launchpad, transaction broadcast
Skills vs MCP vs SDK
| Layer | What It Is | Best For |
|---|---|---|
| Agent Skills | High-level AI instruction set (SKILL.md) with decision trees, workflows, and safety rules | AI coding assistants (Cursor, Claude Code, Codex) |
| MCP Server | Model Context Protocol — 17 tools callable by AI models | AI chat assistants (Claude Desktop, ChatGPT) |
| CLI | Command-line tool with wallet and x402 payment | Scripts, CI/CD, AI agents needing DeFi |
| SDK | TypeScript/Python/Go/Rust client library | Custom applications |
Routing Decision Tree
Skill Comparison
| Aspect | chainstream-data | chainstream-defi |
|---|---|---|
| Pattern | Tool (read-only) | Process (execute) |
| Risk Level | Low | High (irreversible) |
| Wallet Required | No (API Key sufficient) | Yes (signing needed) |
| MCP Support | Full (17 tools) | Tools available, but execution requires wallet on host |
| User Confirmation | Not required | Mandatory before every transaction |
| Typical Actions | Search, analyze, track, stream | Swap, bridge, create, broadcast |
Shared Resources
Both skills share common reference documents:| Resource | Content |
|---|---|
| Authentication | Four auth paths (API Key, wallet login, raw key, Tempo MPP) |
| x402 Payment | x402 and MPP payment protocols, plan selection flow |
| Error Handling | HTTP status codes, retry strategies, DeFi-specific errors |
| Chains | Supported chains matrix, native token addresses, block explorers |
Supported Platforms
Skills work with any AI coding assistant that supportsSKILL.md files:
| Platform | Installation Method |
|---|---|
| Cursor | Auto-discovered via .cursor-plugin/ |
| Claude Code | /plugin install chainstream |
| Codex | Clone + symlink |
| OpenCode | Clone + symlink |
| Gemini CLI | gemini extensions install |
