Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 | $0.00036 | $0.00857 |
| Opus 5.5 | $0.00014 | $0.00343 |
| Sonnet 5.5 | $0.00007 | $0.00171 |
| Haiku 4.5 | $0.00004 | $0.00086 |
Grade A, and why
pentagonal scanned grade A with 1 finding 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 2mo 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Pentagonal — Smart Contract Security & Deployment
Use this skill when the user asks about:
- Auditing smart contracts for vulnerabilities
- Generating Solidity or Anchor/Rust smart contracts
- Deploying contracts to EVM or Solana chains
- Checking contract security or finding bugs
- Creating ERC20/ERC721/SPL tokens
Setup
Set PENTAGONAL_API_URL to your Pentagonal instance (default: https://www.pentagonal.ai).
export PENTAGONAL_API_URL="https://www.pentagonal.ai"
Capabilities
1. Generate Smart Contracts
Generate AI-powered smart contracts from natural language descriptions.
# EVM (Solidity)
bash scripts/pentagonal-generate.sh --chain ethereum --prompt "ERC20 token with burn and pause"
# Solana (Anchor/Rust)
bash scripts/pentagonal-generate.sh --chain solana --type program --prompt "Escrow program with time lock"
# Solana (SPL Token)
bash scripts/pentagonal-generate.sh --chain solana --type token --prompt "Governance token with 1B supply"
2. Audit Smart Contracts
Run AI-powered security audits on existing contract code.
# Audit from file
bash scripts/pentagonal-audit.sh --file ./contracts/MyToken.sol
# Audit from stdin
cat contract.sol | bash scripts/pentagonal-audit.sh --stdin
# Audit with specific focus
bash scripts/pentagonal-audit.sh --file ./contracts/MyToken.sol --focus "reentrancy,access-control"
The audit returns findings classified by severity:
- 🔴 Critical — Must fix before deployment
- 🟠 High — Likely exploitable
- 🟡 Medium — Potential issue
- 🔵 Low — Best practice suggestion
- ⚪ Info — Informational note
3. Deploy Contracts
Deploy compiled contracts to supported chains.
Supported EVM Chains:
- Ethereum (Mainnet, Sepolia)
- Polygon (Mainnet, Amoy)
- BSC (Mainnet, Testnet)
- Arbitrum (Mainnet, Sepolia)
- Base (Mainnet, Sepolia)
- Optimism (Mainnet, Sepolia)
- Avalanche (Mainnet, Fuji)
Supported Solana:
- SPL Token creation (Devnet, Mainnet)
- Anchor program deployment (via Solana Playground guided walkthrough)
What ships with it
5 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.

pentagonal is a skill published in the GitHub repository Pentagonal-ai/pentagonal (1 stars, last pushed 3mo ago), licensed MIT. It adds 36 tokens to every session and 857 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
