specification-architectGenerates or updates highly detailed, machine-readable technical specification documents in the /spec/ directory.
Specification Architect is an agent skill from GulajavaMinistudio/Mayukai-Theme. Generates or updates highly detailed, machine-readable technical specification documents in the /spec/ directory.
Its SKILL.md is about 1.8k 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 Product & Project Management, covering PRD writing. 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.
4 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.
No URLs in SKILL.md.
From 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.
Specification Architect loads about 1.8k tokens when it runs. Until then it costs about 34 tokens; SKILL.md has 492 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.

This skill is used to translate Product Requirements Documents (PRDs) into structured, unambiguous Technical Specifications. It defines the "WHAT" of the technical constraints, data contracts, and acceptance criteria without writing source code. This skill accompanies the @SpecificationArchitect agent.

# Introduction
[A short concise introduction to the specification and the goal it is intended to achieve.]
## 1. Purpose & Scope
[Provide a clear, concise description of the specification's purpose and the scope of its application. State the intended audience and any assumptions.]
## 2. Definitions
[List and define all acronyms, abbreviations, and domain-specific terms used in this specification.]
## 3. Requirements, Constraints & Guidelines
[Explicitly list all requirements, constraints, rules, and guidelines. Use bullet points or tables for clarity.]
- **REQ-001**: Requirement 1
- **SEC-001**: Security Requirement 1
- **CON-001**: Constraint 1
- **GUD-001**: Guideline 1
## 4. Interfaces & Data Contracts
[Describe the interfaces, APIs, data contracts, or integration points. Use tables or code blocks for schemas and examples.]
## 5. Acceptance Criteria
[Define clear, testable acceptance criteria for each requirement using Given-When-Then format where appropriate.]
- **AC-001**: Given [context], When [action], Then [expected outcome]
- **AC-002**: The system shall [specific behavior] when [condition]
## 6. Test Automation Strategy
[Define the testing approach, frameworks, and automation requirements.]
- **Test Levels**: Unit, Integration, End-to-End
- **Test Data Management**: [approach for test data creation and cleanup]
- **CI/CD Integration**: [automated testing pipelines]
- **Coverage Requirements**: [minimum code coverage thresholds]
## 7. Rationale, Context & Architecture Decisions (ADRs)
[Explain the reasoning behind the requirements, constraints, and guidelines. If a "hard-to-reverse" architectural decision was made during the planning phase (e.g., choosing a specific database or protocol), document it here as an ADR (Context, Decision, Consequences).]
## 8. Dependencies & External Integrations
[Define the external systems, services, and architectural dependencies required. Focus on **what** is needed rather than **how** it's implemented.]
### External Systems
- **EXT-001**: [External system name] - [Purpose and integration type]
### Third-Party Services
- **SVC-001**: [Service name] - [Required capabilities and SLA requirements]
### Infrastructure Dependencies
- **INF-001**: [Infrastructure component] - [Requirements and constraints]
### Data Dependencies
- **DAT-001**: [External data source] - [Format, frequency, and access requirements]
## 9. Examples & Edge Cases
` ` `javascript
// Code snippet or data example demonstrating the correct application of the guidelines, including edge cases
` ` `
## 10. Validation Criteria
[List the criteria or tests that must be satisfied for compliance with this specification.]
## 11. Related Specifications / Further Reading

Specification Architect fits situations like: tasks that involve PRD writing.
Run `npx skills add GulajavaMinistudio/Mayukai-Theme --skill specification-architect -a claude-code`. Or copy the skill folder (.agents/skills/specification-architect in GulajavaMinistudio/Mayukai-Theme) into .claude/skills/specification-architect in your project. Claude Code loads it when a task matches its description.
Run `npx skills add GulajavaMinistudio/Mayukai-Theme --skill specification-architect -a codex`. Or copy the skill folder (.agents/skills/specification-architect in GulajavaMinistudio/Mayukai-Theme) into .agents/skills/specification-architect 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 specification-architect -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/specification-architect, .gemini/skills/specification-architect, .github/skills/specification-architect and .opencode/skills/specification-architect in your project.
SKILL.md names no scripts, command-line tools or credentials: Specification Architect is instructions for the agent only.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. 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.
Specification Architect is published under the MIT licence (declared in SKILL.md). It allows redistribution, so the full SKILL.md is shown on this page.
About 1.8k tokens (SKILL.md is roughly 7k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
