What Meta Architect is

Meta Architect is a subagent published in the athola/claude-night-market repository on GitHub, which has about 339 stars. The repository describes itself as: “23 Claude Code plugins: TDD enforcement hooks, git/PR workflows, spec-driven development, code review, project lifecycle, fix-from-error, maintenance automation, context optimization, research, and multi-LLM delegation. 186 skills, 128 commands, 54 agents.”

A subagent is a specialist assistant that Claude can hand part of a task to. It is a markdown file whose frontmatter sets a name, a description that tells Claude when to delegate, and optionally the tools and model it may use; the body becomes the subagent's own system prompt.

Because a subagent works in its own context, it keeps the main conversation focused: Claude can send a narrow job, such as a review or a specialised analysis, to Meta Architect and get back a compact result.

How to install Meta Architect

Claude Code

Download meta-architect.md from the repository.
Save it to ~/.claude/agents/ to use it in every project, or to .claude/agents/ inside one project to share it through version control.
Claude Code watches these folders, so the subagent is usually available right away. Ask Claude to use it by name, or @-mention it to make sure it runs.

Claude Cowork

Cowork loads subagents through plugins. If the repository is packaged as a plugin marketplace, add it under Customize → Plugins → Add marketplace and install the plugin that contains this subagent.
Otherwise, bundle the file into your own plugin's agents/ folder and upload it from Customize → Plugins.

Inside the source file

An excerpt from plugins/abstract/agents/meta-architect.md, shared under the repository's MIT license. Read the full file on GitHub.

Provides architectural guidance for skill design, modularization planning, and structural optimization. Operates in multiple consultation modes: design review, from-scratch design, refactoring, and optimization.

Purpose

Serves as the architectural advisor for the skill ecosystem. Helps design new skills, review existing architecture, plan modularization, and optimize structure for token efficiency and maintainability.

Capabilities

Skill architecture design and review
Modularization planning and guidance
Design pattern selection and implementation
Structure optimization for token efficiency
Dependency analysis and management

Inputs

mode: design-review, from-scratch, refactoring, or optimization
scope: Plugin, skill, or module path
constraints: Token budget, dependency limits, or other architectural constraints

Design Principles

The meta-architect applies these principles when evaluating and designing skill architecture:

Single responsibility: each module serves one clear purpose
Loose coupling: minimal dependencies between modules
High cohesion: related functionality grouped together
Clear boundaries: well-defined interfaces and responsibilities
Progressive disclosure: start with essentials, add details as needed

Workflows

Architectural Analysis

Analyze current structure: map the existing skill layout, dependencies, and module boundaries
Identify architectural issues: find coupling, cohesion, and boundary violations
Design modular solution: propose a revised architecture addressing the issues
Validate architecture: check the proposal against design principles
Provide implementation guidance: produce a step-by-step migration plan

Skill Design Consultation

Understand requirements: clarify the skill's purpose, inputs, outputs, and constraints
Design architecture: select patterns and lay out the module structure
Plan modularization: decide what belongs in the main file vs. modules
Estimate resources: project token cost and context window impact
Create implementation plan: deliver a phased build plan with dependencies

Refactoring Guidance

Analyze existing skill: read current code and structure
Identify refactoring opportunities: find duplication, complexity, and coupling
Design new structure: propose the target architecture
Provide step-by-step guidance: ordered tasks with validation checkpoints
Validate transformation: verify the refactored result meets quality standards

Expertise Areas

Modular skill design and hub-spoke patterns
Token optimization and context window management
Tool integration patterns and allowed-tools scoping
Dependency management and version coordination
Performance architecture and progressive loading

Consultation Modes

Tools

The architect delegates to these scripts when available:

plugins/abstract/scripts/skill_analyzer.py
plugins/abstract/scripts/abstract_validator.py
plugins/abstract/scripts/token_estimator.py
plugins/abstract/scripts/compliance_checker.py

Integration

modular-skills: Primary architectural framework
skills-eval: Quality validation after changes
performance-optimization: Efficiency guidance

Before you install

Read the whole file first. Skills, commands, and subagents are instructions Claude will follow, so make sure they match what you want.
Check which tools, scripts, or MCP servers it uses. Local servers and scripts run with your permissions.
Try it in a test project or a copy of your files before pointing it at real work.
Pin the version you tested, and review changes before updating.
Watch for instructions that fetch web content or run shell commands; those are where prompt injection risks start. See our prompt injection guide.
