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 | $0.00024 | $0.00876 |
| Opus 5 | $0.00012 | $0.00438 |
| Sonnet 5 | $0.00005 | $0.00175 |
| Haiku 4.5 | $0.00002 | $0.00088 |
Grade A, and why
solidity-development scanned grade A with 0 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 8d 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.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 116 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Solidity Development Workflow
Workflow for Solidity smart contract changes in the apps/eth-contracts/ Foundry project.
Prerequisites
Use git-workflow Skill for branch management, commit conventions, and PR creation.
Applicable Directories
| Path | Description |
|---|---|
apps/eth-contracts/contracts/ |
Smart contract source files |
apps/eth-contracts/script/ |
Foundry deployment scripts |
apps/eth-contracts/test/ |
Foundry test files (*.t.sol) |
Toolchain
| Tool | Version | Role |
|---|---|---|
Foundry (forge) |
1.6.0-nightly | Compile, test, deploy |
| Solidity | ^0.8.34 |
Smart contract language |
| OpenZeppelin Contracts | ^5.6.1 |
ERC-20 / standard base contracts |
| bun | primary | npm package manager |
| solhint | ^6.0.3 |
Solidity linter |
| dprint | ^0.52.0 |
JS/TS formatter |
Note:
forgeis installed at~/.foundry/bin/forge(may not be in PATH). Run with full path or add~/.foundry/bintoPATH.
Setup (first time)
cd apps/eth-contracts
# 1. Install forge-std (Foundry testing/scripting library)
forge install foundry-rs/forge-std
# 2. Install npm dependencies (@openzeppelin/contracts, solhint, dprint)
bun install
Verification Commands
cd apps/eth-contracts
forge build # Compile all contracts (artifacts → out/)
forge test -v # Run Foundry unit tests
bun run lint # Solidity lint via solhint (must exit 0, zero errors)
bun run fmt # Format JS/TS files via dprint (must exit 0)
Deployment (local)
cd apps/eth-contracts
export PRIVATE_KEY=0x<deployer-private-key>
forge script script/DeployHYC.s.sol --rpc-url http://localhost:8545 --broadcast
# → outputs contract address, tx hash, gas usage
Compatible with both anvil and geth nodes at http://localhost:8545.
Self-Review Checklist
Code Quality
- Named imports used (
import {Foo} from "...") — no global imports - NatSpec tags present (
@title,@author,@notice,@param) on contracts and public functions - Explicit visibility on all functions (constructors exempt in Solidity ≥0.8)
- Gas optimization considered
- Events emitted for state changes
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.

solidity-development is a skill published in the GitHub repository hiromaily/go-crypto-wallet (127 stars, last pushed 4mo ago), licensed MIT. It adds 24 tokens to every session and 876 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-01.
