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 | $0.00058 | $0.01729 |
| Opus 5 | $0.00029 | $0.00864 |
| Sonnet 5 | $0.00012 | $0.00346 |
| Haiku 4.5 | $0.00006 | $0.00173 |
Grade A, and why
solidity-deploy 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 2d 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.
This is a copy
100% identical to solidity-deploy — 1 line differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 190 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Deployment Workflow
Language Rule
- Always respond in the same language the user is using. If the user asks in Chinese, respond in Chinese. If in English, respond in English.
Pre-deployment Checklist (all must pass)
| Step | Command / Action |
|---|---|
| Format code | forge fmt |
| Run all tests | forge test — zero failures required |
| Check gas report | forge test --gas-report — review critical functions |
| Verify config | Manually check config/*.json parameters |
| Dry-run | forge script <Script> --fork-url <RPC_URL> -vvvv (no --broadcast) |
| Check balance | cast balance <DEPLOYER> --rpc-url <RPC_URL> — sufficient gas? |
| Gas limit set | Deployment command must include --gas-limit |
Deployment Decision Rules
| Situation | Rule |
|---|---|
| Default deployment | No --verify — contracts are not verified on block explorers by default |
| User requests verification | Add --verify and --etherscan-api-key to the command |
| Post-deploy verification | Use forge verify-contract as a separate step |
| Multi-chain deploy | Separate scripts per chain, never batch multiple chains in one script |
| Proxy deployment | Deploy implementation first, then proxy — verify both separately |
| Upgradeable contract | Use OpenZeppelin Upgrades Plugin (see below) — never hand-roll proxy deployment |
Post-deployment Operations (all required)
- Update addresses in
config/*.jsonanddeployments/latest.env - Test critical functions:
cast callto verify on-chain state is correct - Record changes in
docs/CHANGELOG.md - Submit PR with deployment transaction hash link
- If verification needed, run
forge verify-contractseparately
Key Security Rule
- Never pass private keys directly in commands. Use Foundry Keystore (
cast wallet import) to manage keys securely. - Never include
--broadcastin templates. The user must explicitly add it when ready to deploy.

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-deploy is a skill published in the GitHub repository 0xlayerghost/solidity-agent-kit (4 stars, last pushed 22d ago), licensed MIT. It adds 58 tokens to every session and 1,729 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to solidity-deploy, differing in 1 line, and is treated as a copy.
