Technical Overview & Architectural Context

Autonomous coding agents like Claude Code, Codex, and Cursor frequently miss subtle smart contract vulnerabilities—such as missing return value checks, push-over-pull reentrancy, or uninitialized storage pointers—when asked to audit EVM codebases using LLM heuristics alone. Pure LLM audits hallucinate false positives, overlook cross-contract control flows, and consume thousands of context window tokens attempting to parse AST semantics in raw text. The Aderyn Rust-Based Fast Solidity Vulnerability Detector skill anchors agent behavior to Cyfrin's lightning-fast, native Rust static analysis engine. Instead of scanning contract files via unstructured prompts, the agent leverages deterministic AST traversal to produce standardized Markdown reports (report.md) categorized by severity (High, Medium, Low, NC). This skill establishes clear sandbox constraints, enforcing programmatic execution of Aderyn, systematic vulnerability parsing, and targeted code remediation within workspace boundaries.

Prerequisites & Environment Requirements

Foundry (forge 0.2.0+) or Hardhat (v2.19+) initialized in project workspace

Rust toolchain (cargo 1.75+) or standalone Aderyn binary (aderyn 0.1.0+)

Agent runtime with workspace file write permissions (Claude Code CLI, Codex Desktop, Cursor, or Windsurf)

Step-by-Step Execution Playbook

Local Environment Setup & SKILL.md Mounting

Mount the Aderyn skill manifest into your agent's skill registry directory and verify Aderyn CLI accessibility.

Autonomous runtimes discover capabilities through standardized SKILL.md files located in workspace or user-level configuration directories. Mount the skill to `.claude/skills/`, `.cursor/skills/`, or the unified `~/.agents/skills/` directory. Next, verify that the native Rust Aderyn binary is installed and exposed in the execution PATH so the agent can trigger deterministic static checks without missing system binaries.

Production Pro-Tip

Cache Aderyn binary execution inside the agent session by creating a `.aderynignore` file for third-party mock contracts and test folders to prevent redundant AST indexing.

Sandbox Gotcha

Ensure that `shell_exec` is enabled for the workspace if your agent runtime executes the `aderyn .` CLI tool directly rather than relying on a pre-generated AST report.

Project Build Verification & Foundry Artifact Sync

Compile the smart contracts locally so Aderyn can parse Foundry/Hardhat AST artifacts reliably.

Aderyn achieves millisecond speeds by parsing Solidity AST artifacts generated during Foundry or Hardhat compilation. If the workspace contracts fail to compile or lack up-to-date artifacts in `out/` or `artifacts/`, Aderyn will abort with missing AST warnings. Instruct the agent to run a dry compilation pass before invoking static analysis.

Terminal Command

forge build || npx hardhat compile

Production Pro-Tip

Ensure remappings in `remappings.txt` or `foundry.toml` are correctly aligned; Aderyn parses imports strictly according to project configuration.

Sandbox Gotcha

Avoid committing generated `out/` or `artifacts/` directories to Git; keep compilation artifacts local to prevent repository bloat.

Intent Matching & Trigger Invocation

Execute the static analysis scan using natural language triggers that match the skill definition.

Agent engines match prompts against defined triggers such as 'run aderyn audit' or 'scan contracts with aderyn'. When matched, the agent runs the command `aderyn .` from the project root, which reads AST data and emits an organized markdown vulnerability summary in `report.md`.

Production Pro-Tip

Instruct the agent to inspect `report.md` directly and focus only on [H-XX] (High) and [M-XX] (Medium) classifications before reviewing Low/Informational items.

Sandbox Gotcha

If running inside a read-only Docker sandbox, pass `aderyn --stdout .` to stream findings into stdout rather than failing on disk write permission limits.

Automated Remediation & Verification Quality Gate

Apply patches for identified vulnerabilities and verify fixes through automated test suites.

Following Aderyn report generation, the agent systematically refactors vulnerable code (e.g., adding explicit return value checks or OpenZeppelin ReentrancyGuard). Once remediated, the agent re-runs `aderyn .` to ensure the finding is resolved, followed by test execution to ensure zero functional regressions.

Terminal Command

aderyn . && forge test

Production Pro-Tip

Check `git diff` against contracts before accepting agent pull requests to confirm no unauthorized interface changes occurred during remediation.

Real-World Scenario: Automated AST Vulnerability Triage and Remediation on a Foundry Vault Contract

Tested Trigger Prompt (Feed directly into Codex, Claude, or Cursor):

“Run aderyn audit on our core vault contract src/Vault.sol, fix any high or medium severity vulnerabilities detected in report.md, and ensure forge test passes.”

Deterministic Agent Verification Pipeline:

Agent executes `forge build` to verify Solidity AST freshness.

Agent runs `aderyn .` in the project root to scan contracts and generate `report.md`.

Agent parses `report.md`, identifying an unhandled ERC20 return value (Medium) and missing zero-address validation (Low).

Agent refactors `src/Vault.sol` using OpenZeppelin's `SafeERC20` wrapper (`safeTransferFrom`).

Agent re-executes `aderyn .` to verify that `report.md` contains 0 High and 0 Medium issues.

Agent runs `forge test` and verifies all vault invariant tests pass cleanly.

Runtime Troubleshooting & Failure Modes

Error: Error: Failed to parse Foundry project: Could not locate foundry.toml or out directory

Root Cause: Aderyn was executed in a directory without an initialized Foundry configuration or before `forge build` generated AST JSON outputs.

Resolution Command / Fix:

forge build && aderyn .

Error: aderyn: command not found (exit code 127)

Root Cause: The Cargo binary path is missing from the agent runtime environment's PATH variable.

Resolution Command / Fix:

export PATH="$HOME/.cargo/bin:$PATH" && which aderyn || cargo install aderyn

Frequently Asked Questions (Aderyn Rust-Based Fast Solidity Vulnerability Detector SOP)

Q:Can I use Aderyn Rust-Based Fast Solidity Vulnerability Detector across Codex, Claude Code, and Cursor simultaneously?

Yes. The SKILL.md specification is fully platform-agnostic and compatible across Codex, Claude Code CLI, Cursor, and Windsurf agent environments.

Q:How does Aderyn Rust-Based Fast Solidity Vulnerability Detector prevent context window overflow during long agent sessions?

Aderyn compiles AST data locally in native Rust and outputs structured summaries directly to report.md. The agent only reads relevant vulnerability blocks rather than ingesting full raw codebases into context.

Q:Does this skill require escalated root or container permissions?

No. The skill operates strictly within the workspace filesystem, requires no elevated privileges, and earned a 98/100 verified security score.
