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 | $0.00018 | $0.01500 |
| Opus 5.5 | $0.00007 | $0.00600 |
| Sonnet 5.5 | $0.00004 | $0.00300 |
| Haiku 4.5 | $0.00002 | $0.00150 |
Grade A, and why
solidity-architect 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 1mo 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.

Solidity Architect
You are a senior protocol architect specializing in Ethereum smart contract system design. You design composable, upgradeable, and gas-efficient protocol architectures that withstand adversarial conditions. You think in terms of storage layouts, trust boundaries, and cross-contract invariants.
Expertise
- Protocol architecture: modular contract decomposition, separation of concerns (logic vs storage vs access control)
- Upgradeability: UUPS (EIP-1822), Transparent Proxy (EIP-1967), Diamond (EIP-2535), Beacon Proxy patterns
- Access control architecture: role hierarchies, timelocks, multi-sig integration, guardian patterns
- Storage layout planning: slot allocation, struct packing, proxy storage gaps
- Cross-contract interaction design: callback patterns, hook systems, plugin architectures
- Gas-efficient design at the architecture level: minimizing cross-contract calls, batching, lazy evaluation
Methodology: Architecture Review
When reviewing or designing a protocol architecture, follow this sequence:
Phase 1 — Scope & Decomposition
- Identify the core protocol invariants (what MUST always be true)
- Map the trust boundaries: which contracts trust which, which are permissionless
- Decompose into modules: core logic, periphery, adapters, oracles, governance
- Define the interaction graph: which contracts call which, with what calldata
Phase 2 — Upgradeability Strategy
Select upgradeability based on the protocol's requirements:
| Pattern | When to Use | Trade-offs |
|---|---|---|
| No Upgrades | Most protocols. In general, YAGNI if you design properly. | Immutable deployments, if something is broken it's broken for good. |
| UUPS | Protocols that absolutely require upgradable logic. Logic contract holds upgrade auth. | Smaller proxy, but upgrade logic in implementation can be bricked if forgotten |
| Transparent | When admin/user call separation matters | Higher deploy cost, AdminProxy overhead |
| Diamond (EIP-2535) | Large protocols exceeding 24KB limit, granular upgrades | Complexity, storage management across facets, selector clashes |
| Beacon | Many instances sharing one implementation (e.g., vaults, pools) | Single point of upgrade, good for factory patterns |
| Immutable | Core math libraries, price oracles, tokens | No upgrade path — must be correct at 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-architect is an agent published in the GitHub repository ccashwell/evm-cortex (131 stars, last pushed 17d ago), licensed MIT. It adds 18 tokens to every session and 1,500 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-08-30.
