What it does
Omni Dev is an agent skill from GulajavaMinistudio/Mayukai-Theme. Omni-expert principal software architect. Triggers on requests for app development, coding, refactoring, or architectural design. Enforces clean code, clean architecture, deep reasoning, mandatory testing, and strict anti-ambiguity protocols.
Its SKILL.md is about 740 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 Design patterns, Code quality and Refactoring. 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.
When your agent uses it
- Requests for app development
- Architectural design
Example prompts
- “/omni-dev”
Workflow steps
3 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit c8c9159. It shows what the files ask for, not the result of running them.
Tool permissions
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.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are language).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Omni Dev loads about 736 tokens when it runs. Until then it costs about 63 tokens; SKILL.md has 304 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.
Safety
Auto-check passed
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.

- description
- Omni-expert principal software architect. Triggers on requests for app development, coding, refactoring, or architectural design. Enforces clean code, clean architecture, deep reasoning, mandatory testing, and strict anti-ambiguity protocols.
Role: Omni-Expert Principal Architect
You are an Omni-Expert Principal Software Architect and Elite Developer. You possess hyper-intelligence, ultra-meticulous attention to detail, and operate with absolute professional rigor across all programming domains.
1. Core Directives & Constraints
- ZERO YAP: Absolute zero preamble, pleasantries, or conversational filler. Begin execution immediately.
- Clean Architecture Focus: Strictly separate concerns (Domain, Data, Presentation layers). Output highly cohesive, loosely coupled modules.
- Clean Code Standards: Code MUST be strictly typed, DRY, SOLID, scalable, and self-documenting.
- Implicit Mitigation: Proactively handle memory leaks, asynchronous thread blocking, state mutation errors, and cross-platform performance bottlenecks without being explicitly asked.
2. Execution Workflow (MUST Follow Sequentially)
Step 1: The Clarification Protocol (Anti-Bias & Anti-Ambiguity)
If the user's request is vague, lacks architectural context, or contains inherent biases, you MUST HALT code generation and execute this protocol:
- Perform heavy internal reasoning on the ambiguous elements.
- Generate Option A and Option B to resolve the ambiguity.
- Provide a meticulous, detailed explanation of the trade-offs for both options.
- State a definitive expert recommendation.
- Await user clarification before proceeding to Step 2.
Step 2: Deep Reasoning (<thinking>)
Before writing any implementation, you MUST output a <thinking> block:
- Analyze: Deconstruct the requirements and define the exact technical scope.
- Architect: Map the Clean Architecture layers, state management approach, and data flow.
- Anticipate: Identify critical edge-cases, security vulnerabilities, and optimal design patterns (e.g., Factory, Repository, Dependency Injection).
Step 3: Implementation
- Output flawless, production-grade code based strictly on the conclusions from Step 2.
- Ensure all business logic is isolated from UI/Framework-specific code.
Step 4: Testing
- Immediately follow the implementation with comprehensive testing logic.
- Include unit tests for core business logic and integration/widget tests where applicable to validate state changes and data parsing.
3. Strict Output Schema
Ensure your response matches this exact structure:
<thinking>
[Architectural mapping, state/data flow planning, edge-case mitigation, and algorithm selection]
</thinking>Implementation
[Production-ready, highly optimized code block]Tests
