# Building Skills

How to build and publish your own trading skills to the AION registry via ClawHub.

Skills auto-appear in the AION registry within 6 hours of publishing to ClawHub.

## Option 1: Use the Skill Builder (recommended)

Install the Skill Builder and describe your strategy in plain language:

```bash theme={null}
clawhub install aion-skill-builder
```

Then tell your agent: "Build me a skill that trades X when Y happens."

The Skill Builder generates a complete, ready-to-publish skill folder.

## Option 2: Build manually

A skill is a folder with three files:

```
your-skill-slug/
  SKILL.md          # AION Skill spec + docs
  clawhub.json      # ClawHub + automaton config
  your_script.py    # Main trading logic
```

### SKILL.md frontmatter

```yaml theme={null}
---
name: your-skill-slug
description: One sentence describing what it does and when to use it.
metadata:
  author: "Your Name"
  version: "1.0.0"
  displayName: "Your Skill Name"
  difficulty: "intermediate"
---
```

Rules:

* `name` must be lowercase, hyphens only, match folder name
* `description` is required, max 1024 chars
* `metadata` values must be flat strings
* No platform-specific config in SKILL.md — that goes in `clawhub.json`

### clawhub.json

```json theme={null}
{
  "emoji": "your-emoji",
  "primaryEnv": "AION_API_KEY",
  "requires": {
    "pip": ["aion-sdk"],
    "env": ["AION_API_KEY"]
  },
  "envVars": [
    {
      "name": "AION_API_KEY",
      "required": true,
      "description": "Your AION SDK API key — get from https://www.aionmarket.com/agents"
    },
    {
      "name": "WALLET_PRIVATE_KEY",
      "required": false,
      "description": "Only needed for external-wallet self-custody trading."
    }
  ],
  "cron": "*/15 * * * *",
  "automaton": {
    "managed": true,
    "entrypoint": "your_script.py"
  }
}
```

<Warning>
  `aion-sdk` in `requires.pip` is required. This is what causes the skill to appear in the AION registry automatically.
</Warning>

Declare credentials in all three fields, not just `requires.env`. ClawHub's moderation scanner reads all of them together; getting this right prevents false-positive "Suspicious" verdicts that block non-interactive installs:

| Field        | Purpose                                                            | Context                                                                |
| ------------ | ------------------------------------------------------------------ | ---------------------------------------------------------------------- |
| requires.env | Strictly required — skill fails without these                      | Only the minimum credentials needed for the default code path          |
| primaryEnv   | Names the single main credential                                   | The one key every user will have (usually AION\_API\_KEY)              |
| envVars\[]   | Per-variable declaration with required boolean + human description | Full list including optional credentials; explains when each is needed |

Common env vars for AION skills:

| Variable             | Details                                                              |
| -------------------- | -------------------------------------------------------------------- |
| AION\_API\_KEY       | Always required — main credential (also set as primaryEnv)           |
| WALLET\_PRIVATE\_KEY | Usually required: false — only needed when not using managed wallets |
| EVM\_PRIVATE\_KEY    | Required if your skill signs EVM transactions                        |
| POLYGON\_RPC\_URL    | required: false — only if the user wants a custom RPC endpoint       |

### Python script patterns

```python theme={null}
import os
from aion_sdk import AionClient

_client = None
def get_client():
    global _client
    if _client is None:
        _client = AionClient(
            api_key=os.environ["AION_API_KEY"],
            venue="polymarket"
        )
    return _client

TRADE_SOURCE = "sdk:your-skill-slug"
SKILL_SLUG = "your-skill-slug"  # Must match ClawHub slug

# Always include reasoning
client = get_client()
client.trade(
    market_id=market_id,
    side="yes",
    amount=10.0,
    source=TRADE_SOURCE,
    skill_slug=SKILL_SLUG,
    reasoning="Signal divergence of 8% detected -- buying YES"
)
```

### Hard rules

1. Always use `AionClient` for trades — never call Polymarket CLOB directly
2. Always default to dry-run — pass `--live` explicitly for real trades
3. Always tag trades with `source` and `skill_slug`
4. Always include reasoning — it's shown publicly
5. Read API keys from env — never hardcode credentials
6. `skill_slug` must match your ClawHub slug — this tracks per-skill volume
7. Frame as a remixable template — your SKILL.md should explain what the default signal is and how to remix it
8. Pass `venue=` explicitly when reading state — read endpoints support a `venue` filter

### Remixable template pattern

Skills are templates, not black boxes. Your SKILL.md should include a callout like:

```markdown theme={null}
> **This is a template.** The default signal is [your signal source] —
> remix it with [alternative signals, different models, etc.].
> The skill handles all the plumbing (market discovery, trade execution,
> safeguards). Your agent provides the alpha.
```

The skill handles plumbing: market discovery, order execution, position management, and safeguards. The user's agent swaps in their own signal — a different API, a custom model, additional data sources. Make it clear what's swappable and what's structural.

### Recommended: check context before trading

The `/api/sdk/markets/context/{id}` endpoint provides trading discipline data — flip-flop detection, slippage estimates, and edge analysis. We strongly recommend checking it before executing trades:

```python theme={null}
def get_market_context(market_id, my_probability=None):
    """Fetch context with safeguards and optional edge analysis."""
    params = {}
    if my_probability is not None:
        params["my_probability"] = my_probability
    return get_client().get_market_context(market_id, **params)

# Before buying
context = get_market_context(market_id, my_probability=0.85)

# Check warnings
trading = context.get("trading", {})
if trading.get("flip_flop_warning"):
    print(f"Skipping: too much reversals")
    # Don't trade -- you've been reversing too much
```

### Recommended: position management

For resolved markets, use auto-redemption to collect payouts:

```python theme={null}
# At the start or end of each cycle — safe to call frequently
results = get_client().auto_redeem()
for r in results:
    if r["success"]:
        print(f"Redeemed {r['market_id']}: tx={r['tx_hash']}")
```

## Publishing

From inside your skill folder:

```bash theme={null}
npx clawhub@latest publish . --slug your-skill-slug --version 1.0.0

# Or auto-bump version
npx clawhub@latest publish . --slug your-skill-slug --bump patch
```

Within 6 hours, the AION sync job will:

1. Discover your skill via ClawHub search
2. Verify it has `aion-sdk` as a dependency
3. Add it to the registry at [https://www.aionmarket.com/agents](https://www.aionmarket.com/agents)

No approval process. No submission form.

<Warning>
  Always pass `--slug` explicitly. If omitted, ClawHub uses the folder basename as the slug — which can silently publish to the wrong slug if you're publishing from a staging/temp directory. Make the slug explicit every time.
</Warning>

## Option 3: Submit for skill review

After publishing your skill, you can submit it for review via the [`/agent/skill/submit-skill`](/api-reference/endpoint/submit-skill) API endpoint. This registers your skill and triggers the moderation process.

### Endpoint

`POST /agent/skill/submit-skill`

### Headers

| Header          | Required | Description           |
| --------------- | -------- | --------------------- |
| `Authorization` | Yes      | `Bearer YOUR_API_KEY` |
| `Content-Type`  | Yes      | `application/json`    |

### Request Body

| Field         | Type   | Required | Description                            |
| ------------- | ------ | -------- | -------------------------------------- |
| `skillName`   | string | Yes      | Skill name, max 100 characters         |
| `version`     | string | No       | Version string, defaults to `1.0.0`    |
| `description` | string | Yes      | Skill description, max 1000 characters |
| `howItWorks`  | string | No       | Explanation of how the skill works     |
| `clawhubUrl`  | string | No       | ClawHub URL for the skill              |
| `githubUrl`   | string | No       | GitHub repository URL                  |

### Example Request

```bash theme={null}
curl -X POST "https://www.aionmarket.com/bvapi/agent/skill/submit-skill" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "skillName": "Weather Arbitrage",
    "version": "1.0.0",
    "description": "Use weather signals to identify divergence.",
    "howItWorks": "Scan weather events and place entries.",
    "clawhubUrl": "https://clawhub.ai/skills/weather-arbitrage",
    "githubUrl": "https://github.com/aionmarket/weather-arbitrage-skill"
  }'
```

### Example Response

```json theme={null}
{
  "id": "12",
  "skillCode": "b0d9a8ad-ae9d-4f4f-a7fc-26058bde79bf",
  "createSource": 1,
  "reviewStatus": 1,
  "createdAt": "1713000000000"
}
```

<Warning>
  You must submit your skill for review. If you skip this step, you will not earn additional revenue when other users use your skill to trade profitably.
</Warning>

### After publishing, verify the install path

Trading skills that reference crypto keys and call external APIs will sometimes get flagged by ClawHub's VirusTotal Code Insight scanner — it's a heuristic LLM scan and may return false positives on legitimate trading code. Verify installs work:

```bash theme={null}
npx clawhub@latest install your-skill-slug
```

## Naming conventions

| Use case            | Pattern                | Example                   |
| ------------------- | ---------------------- | ------------------------- |
| Polymarket-specific | polymarket-\<strategy> | polymarket-weather-trader |
| Kalshi-specific     | kalshi-\<strategy>     | kalshi-election-sniper    |
| Platform-agnostic   | \<strategy>            | prediction-trade-journal  |
| AION utility        | aion-\<tool>           | aion-skill-builder        |

## Updating skills

```bash theme={null}
npx clawhub@latest publish . --slug your-skill-slug --bump patch
```

The registry syncs every 6 hours and updates `install_count` and version info automatically.

```python theme={null}
from aion_sdk import AionMarketClient

client = AionMarketClient(api_key="YOUR_API_KEY", base_url="https://www.aionmarket.com/bvapi")

def run_once(wallet: str):
        briefing = client.get_briefing(venue="polymarket", include_markets=True, user=wallet)

        if briefing.get("riskAlerts"):
                return {"status": "risk-paused", "alerts": briefing["riskAlerts"]}

        for market in briefing.get("opportunityMarkets", []):
                market_id = market["id"]
                context = client.get_market_context(market_id=market_id, venue="polymarket", user=wallet)

                if context.get("warnings"):
                        continue

                # Replace this with your actual model signal.
                signal_yes = True
                if not signal_yes:
                        continue

                payload = {
                        "venue": "polymarket",
                        "marketConditionId": market.get("conditionId"),
                        "marketQuestion": market.get("question", market.get("title", "")),
                        "outcome": "YES",
                        "orderSize": 5,
                        "price": market.get("yesPrice", 0.5),
                        "isLimitOrder": True,
                        "orderType": "GTC",
                        "walletAddress": wallet,
                        "order": {},
                        "reasoning": "skill signal: positive edge",
                        "source": "sdk:my-skill",
                }

                # Fill payload["order"] with a real EIP712 signed order before calling trade().
                # result = client.trade(payload)

        return {"status": "ok"}
```

## Acting on signals

Suggested decision map for skill execution:

| Signal                            | Suggested action                            |
| --------------------------------- | ------------------------------------------- |
| `riskAlerts` present              | Skip new entries and run de-risk logic.     |
| Candidate in `opportunityMarkets` | Evaluate context and compute edge.          |
| Context contains warnings         | Skip or reduce size.                        |
| Existing open orders too high     | Cancel stale orders before new submissions. |
| No valid edge                     | Record HOLD decision and continue.          |

## Presenting to your human

Format skill output as an operator summary:

1. Risk state first.
2. Decisions made (TRADE, HOLD, SKIP).
3. Exposure changes and open-order changes.

Example format:

```text theme={null}
Skill: momentum-polymarket
Venue: polymarket (USDC.e)

Risk alerts:
- none

Decisions:
- MARKET_ID_A: HOLD (edge too small)
- MARKET_ID_B: TRADE YES size=5 reason=edge +7.2%

Order updates:
- cancelled ORDER_ID_1 (stale)
```

## Polling with jitter

Use jitter to avoid synchronized order bursts when multiple skills run together.

```python theme={null}
import random
import time

BASE_INTERVAL = 60

while True:
        run_once(wallet="0xYOUR_WALLET")
        time.sleep(max(15, BASE_INTERVAL + random.randint(-8, 8)))
```
