Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00033 | $0.00814 |
| Opus 5 | $0.00016 | $0.00407 |
| Sonnet 5 | $0.00007 | $0.00163 |
| Haiku 4.5 | $0.00003 | $0.00081 |
Grade C, and why
huginn-onboard scanned grade C with 2 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 12d 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.

Huginn Onboarding Skill
Goal: Enable any agent on any EVM chain to onboard to Starknet and register their identity with the HuginnRegistry.
When to Use
- Bridging an agent from an EVM chain to Starknet and registering it with Huginn.
- Standing up first-run onboarding flows that require funding, account deployment, and agent registration.
When NOT to Use
- Generic Starknet wallet management without Huginn registration.
- Cairo contract authoring, deployment-only runbooks, or security audits.
Related modules: skills catalog.
Prerequisites
- Agent has ETH or USDC on source chain (Ethereum, Base, or Arbitrum)
- Agent can sign transactions
- Basic HTTP/RPC access
Step 1: Bridge to Starknet
Use AVNU bridge to transfer funds:
# Get bridge quote
curl -X POST "https://api.avnu.fi/v1/bridge/quote" \
-H "Content-Type: application/json" \
-d '{
"fromChain": "ethereum",
"toChain": "starknet",
"fromToken": "ETH",
"toToken": "ETH",
"amount": "0.01",
"slippage": 0.5
}'
# Execute bridge transaction
# (Use response calldata with your signer)
Step 2: Deploy Agent Account
Deploy a Starknet account contract:
# Using starknet.js or similar
npx starknet-account deploy \
--network mainnet \
--implementation 0x... # Agent account class hash
Step 3: Register with Huginn
Call HuginnRegistry.register_agent():
import { Contract, Account } from "starknet";
const registry = new Contract(
HUGINN_ABI,
"0x...", // HuginnRegistry address
provider
);
// Register your agent
await registry.register_agent(
"MyAgent", // felt252 name
"ipfs://QmXXX" // metadata URL
);
// Emits OdinEye event - you're registered!
Step 4: Log Your First Thought
import { hash } from "starknet";
const thoughtHash = hash.starknetKeccak("Hello Starknet!");
await registry.log_thought(thoughtHash);
// Emits RavenFlight event - your thought is on-chain!

What ships with it
4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
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.

huginn-onboard is a skill published in the GitHub repository keep-starknet-strange/starknet-agentic (80 stars, last pushed 3d ago), licensed MIT. It adds 33 tokens to every session and 814 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it C with 2 findings (downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
