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 | $0.00104 | $0.01234 |
| Opus 5.5 | $0.00042 | $0.00494 |
| Sonnet 5.5 | $0.00021 | $0.00247 |
| Haiku 4.5 | $0.00010 | $0.00123 |
Grade A, and why
solidity-auditor 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 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.
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 — 129 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Solidity Smart Contract Auditor
A professional-grade smart contract audit skill covering security vulnerabilities, gas optimization, storage patterns, and code architecture. Adapted to Solidity version specifics.
Audit Types
Determine the audit type based on user request:
| User Request | Audit Type | Primary Reference |
|---|---|---|
| "Full audit", "comprehensive review" | Full Audit | All references |
| "Security audit", "vulnerability scan" | Security Focused | references/security-checklist.md |
| "Gas optimization", "reduce gas costs" | Gas Optimization | references/gas-optimization.md |
| "Storage optimization", "storage patterns" | Storage Optimization | references/storage-optimization.md |
| "Code review", "architecture review" | Architecture Review | references/architecture-review.md |
| "DeFi audit", "protocol review" | DeFi Protocol | Security + Architecture references |
Core Audit Workflow
Phase 1: Preparation
-
Identify Solidity Version: Check pragma statement. Read
references/version-specific.mdfor version-specific considerations:- Pre-0.8.0: Check for SafeMath usage, arithmetic vulnerabilities
- 0.8.0+: Review
uncheckedblocks, check custom errors usage
-
Understand Scope:
- List all contracts, interfaces, libraries
- Identify external dependencies (OpenZeppelin, etc.)
- Note inheritance hierarchy
- Document entry points (external/public functions)
-
Gather Context: Ask if not provided:
- Protocol purpose and intended behavior
- Deployment chain(s)
- Expected user flows
- Admin roles and privileges
Phase 2: Static Analysis
-
Run automated checks mentally using patterns from the security checklist:
- Access control patterns
- State-changing operations flow (checks-effects-interactions)
- External call patterns
- Arithmetic operations (especially in
uncheckedblocks)
-
Map attack surface:
- External/public functions
- Functions handling ETH/tokens
- Functions with access control
- Upgrade mechanisms
What ships with it
6 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.

solidity-auditor is a skill published in the GitHub repository schwepps/skills (17 stars, last pushed 9mo ago), licensed MIT. It adds 104 tokens to every session and 1,234 once invoked, about $0.0004 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.
