What Are Skills?

Skills are self-contained capability modules. Each skill ships:
  • A script directory with TypeScript scripts the agent can invoke
  • A SKILL.md manifest that tells the agent exactly what it can do, what parameters to pass, and what to expect back
The agent reads SKILL.md at startup and immediately knows how to call the skill — no hardcoded capability lists in your system prompt, no outdated documentation.

​
The Manifest System

When you provision a wallet, a GLOSSO.md is written to your working directory. It aggregates all installed skills into one file: 
# GLOSSO — Capability Manifest

## Installed Skills

### glosso-wallet
- glosso_balance(index?, includeTokens?) → { address, sol, tokens }
- glosso_send(to, amountSol, index?) → { signature, explorer }
- glosso_history(index?, limit?) → { transactions }

### glosso-pyth
- glosso_price(symbol) → { symbol, price, confidence, ts }

### glosso-jupiter
- glosso_quote(inputMint, outputMint, amount) → { inAmount, outAmount, priceImpact }
- glosso_swap(inputMint, outputMint, amount) → { signature }
The agent passes this as a section of its system prompt — it knows what it can do, what parameters each function takes, and what to expect back.

​
Available Skills

glosso-wallet

SOL balance checks, transfers, and transaction history.

glosso-pyth

Real-time price feeds for SOL, BTC, ETH, USDC, JUP, BONK and more via Pyth Network.

glosso-jupiter

Token swap quotes and execution via the Jupiter aggregator.

OpenClaw install

Install all skills onto an OpenClaw agent VM with one command.

​
How Skills Are Loaded

At provision time, Glosso writes GLOSSO.md to the current directory by scanning ~/.openclaw/skills/glosso-*/SKILL.md (or the local packages/skills/ directory). The GLOSSO.md is a concatenation of each skill’s capabilities section. In your agent: 
import fs from 'fs';

const glossoMd = fs.existsSync('./GLOSSO.md')
  ? fs.readFileSync('./GLOSSO.md', 'utf-8')
  : '';

const systemPrompt = `
You are an autonomous Solana agent.

${glossoMd}

Use the tools above to complete the user's request.
`.trim();

​
Anatomy of a SKILL.md

Each SKILL.md is a machine-readable manifest with frontmatter and structured sections: 
---
name: glosso-wallet
description: Solana wallet for AI agents. ...
metadata: {"openclaw": {"emoji": "💳", "requires": {"bins": ["node"]}}}
---

## Available Functions

### glosso_balance(index?, includeTokens?)
**Script:** tsx scripts/balance.ts
**Returns:** { address, sol, tokens }
...
The frontmatter description field is injected into the agent’s tool discovery. The body documents each function the agent may call.
Skills are just TypeScript scripts + a manifest. You can write your own — see Writing a Skill.
