expert-code-reviewerLanguage-agnostic workflow for code reviews and security audits against Clean Code/SOLID principles, generating formal refactoring plans.
Expert Code Reviewer is an agent skill from GulajavaMinistudio/Mayukai-Theme. Language-agnostic workflow for code reviews and security audits against Clean Code/SOLID principles, generating formal refactoring plans.
Its SKILL.md is about 1.4k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Development, covering Code review, Refactoring and Security review. It works with Visual Studio Code. The repository describes itself as: Combination theme for VS Code and VSCodium that inspired from Ayu Theme, Monokai , Andromeda, Material Color, and Gruvbox Darktooth Color. The licence is MIT.
2 steps, taken from the step headings in SKILL.md.
Read from SKILL.md and the folder at commit c8c9159. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
No scripts in the folder and no shell commands in SKILL.md (its code samples are markdown).
From the folder's file list and the shell code blocks in SKILL.md.
Hosts in commands or code, which the agent is likely to contact:
img.shields.ioFrom URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Expert Code Reviewer loads about 1.4k tokens when it runs. Until then it costs about 40 tokens; SKILL.md has 268 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

# Introduction

[A short concise introduction to the refactoring plan, the technical debt being addressed, the architectural goal, and any security vulnerabilities being remediated.]
## 1. Requirements & Constraints (Architecture & Security Focus)
[Explicitly list the architectural and security principles guiding this refactoring.]
- **REQ-001**: Requirement 1
- **PRN-001**: Architectural Principle (e.g., Ensure Single Responsibility Principle)
- **SEC-001**: Security Requirement (e.g., Prevent SQL Injection via parameterized queries)
- **CON-001**: Constraint 1
## 2. Implementation Steps
> **⚠️ EXECUTION DIRECTIVE FOR AI AGENTS:**
> You MUST execute this plan phase by phase. You MUST run the specific testing/verification task at the end of each phase. After a phase is tested, you **MUST STOP AND WAIT** for the user's explicit approval before proceeding to the next phase.
### Implementation Phase 1: Security Remediation & Decoupling
- GOAL-001: [Describe the goal of this phase]
| Task | Description | Completed | Date |
| -------- | ----------------------------------------------------------------------- | --------- | ---- |
| TASK-001 | Description of task 1 (include exact file paths) | | |
| TASK-00X | **VERIFY**: [Specific testing/verification step for this phase] | | |
| TASK-00Y | **APPROVAL**: Wait for explicit user confirmation to proceed to Phase 2 | | |
### Implementation Phase 2: Core Architectural Refactoring
- GOAL-002: [Describe the goal of this phase]
| Task | Description | Completed | Date |
| -------- | --------------------------------------------------------------- | --------- | ---- |
| TASK-003 | Description of task 3 | | |
| TASK-00X | **VERIFY**: [Specific testing/verification step for this phase] | | |
| TASK-00Y | **APPROVAL**: Wait for explicit user confirmation to proceed | | |
## 3. Alternatives
[A bullet point list of any alternative architectural/security approaches considered.]
- **ALT-001**: Alternative approach 1
## 4. Dependencies
[List any new dependencies introduced or removed, including security libraries or sanitization packages.]
- **DEP-001**: Dependency 1
## 5. Files Affected
[List all files that will be modified, deleted, or created.]
- **FILE-001**: Description of file 1
## 6. Testing
[List the tests that need to be updated or implemented to verify behavior and ensure security vulnerabilities are patched. Phase-specific tests are in the Implementation Steps.]
- **TEST-001**: Description of test 1
## 7. Risks & Assumptions
[List any risks related to the refactoring or potential edge cases in the security patch.]
- **RISK-001**: Risk 1© GulajavaMinistudio, MIT. Rendered from Markdown: HTML in the file is shown as text, images as links, and headings moved down two levels. Raw file

Expert Code Reviewer fits situations like: tasks that involve Code review; tasks that involve Refactoring; tasks that involve Security review.
Run `npx skills add GulajavaMinistudio/Mayukai-Theme --skill expert-code-reviewer -a claude-code`. Or copy the skill folder (.agents/skills/expert-code-reviewer in GulajavaMinistudio/Mayukai-Theme) into .claude/skills/expert-code-reviewer in your project. Claude Code loads it when a task matches its description.
Run `npx skills add GulajavaMinistudio/Mayukai-Theme --skill expert-code-reviewer -a codex`. Or copy the skill folder (.agents/skills/expert-code-reviewer in GulajavaMinistudio/Mayukai-Theme) into .agents/skills/expert-code-reviewer in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add GulajavaMinistudio/Mayukai-Theme --skill expert-code-reviewer -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/expert-code-reviewer, .gemini/skills/expert-code-reviewer, .github/skills/expert-code-reviewer and .opencode/skills/expert-code-reviewer in your project.
SKILL.md names no scripts, command-line tools or credentials: Expert Code Reviewer is instructions for the agent only.
SKILL.md names 1 domain. In commands or code: img.shields.io; the agent is likely to contact it when it follows the instructions. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Expert Code Reviewer is published under the MIT licence (declared in SKILL.md). It allows redistribution, so the full SKILL.md is shown on this page.
About 1.4k tokens (SKILL.md is roughly 5.7k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
