Stacks Agent - OpenAI Codex Skill

Stacks blockchain development intelligence for Codex.

Skill Overview

AI-powered assistance for building on Stacks - Bitcoin's smart contract layer.

Capabilities

Generate and audit Clarity smart contracts
SIP-010 fungible tokens and SIP-009 NFTs
DeFi protocol integration (Alex, Velar, Bitflow, Zest)
Security vulnerability detection and fixes
Stacks.js frontend integration
BNS name system operations
PoX stacking and pool delegation
Deployment guides (testnet, mainnet, devnet)

Knowledge Base

170+ searchable entries across 8 domains:

python3 .shared/stacks-agent/scripts/search.py "<query>" --domain <domain>

Domains:

clarity - 61 functions and types
templates - 14 contract templates
security - 15 security patterns
defi - 15 DeFi protocols
stacksjs - 30 JavaScript snippets
bns - 10 name system operations
stacking - 15 stacking guides
deployment - 25 deployment steps

Workflow

Analyze user request (contract type, features, network)
Search knowledge base for relevant patterns
Generate code following Clarity best practices
Apply security patterns automatically
Provide deployment instructions

Code Generation Rules

Always Include

Access control checks (tx-sender validation)
Error handling (try!, unwrap!)
Input validation (asserts!)
Named error constants (ERR-*)
Kebab-case naming
Documentation comments

Never Include

unwrap-panic in production code
Hardcoded magic numbers
Unvalidated external calls
Missing return value checks

Security Patterns

Critical

Validate tx-sender for sensitive operations
Check all transfer return values
Handle errors explicitly

High

Validate all inputs
Prevent division by zero
Update state before external calls

Medium

Prevent self-transfers
Restrict minting functions
Use tx-sender not contract-caller

Example Outputs

Token Contract

(define-fungible-token my-token u1000000)
(define-constant ERR-UNAUTHORIZED (err u100))
(define-constant ERR-INVALID-AMOUNT (err u101))

(define-public (transfer (amount uint) (recipient principal))
  (begin
    (asserts! (> amount u0) ERR-INVALID-AMOUNT)
    (try! (ft-transfer? my-token amount tx-sender recipient))
    (ok true)))
