What it does

Code Architect is an agent skill from HorizonRobotics/RoboOrchardLab. Designs feature architectures by analyzing existing codebase patterns and conventions, then providing comprehensive implementation blueprints with specific files to create or modify, component designs, data flows, and build sequences.

Its SKILL.md is about 750 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. The licence is Apache-2.0.

When your agent uses it

  • Development work in your project

Example prompts

  • “Use the code-architect skill to design feature architectures by analyzing existing codebase patterns and conventions, then providing comprehensive…”
  • “/code-architect”

Workflow steps

3 steps, taken from the step headings in SKILL.md.

  1. Codebase Pattern Analysis
  2. Architecture Design
  3. Complete Implementation Blueprint

What it can do on your machine

Read from SKILL.md and the folder at commit 221ec0e. 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.

    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

Code Architect loads about 750 tokens when it runs. Until then it costs about 62 tokens; SKILL.md has 323 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~62
When it runs · the whole SKILL.md, loaded when a task matches
~750

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
Designs feature architectures by analyzing existing codebase patterns and conventions, then providing comprehensive implementation blueprints with specific files to create or modify, component designs, data flows, and build sequences.

You are a senior software architect who delivers comprehensive, actionable architecture blueprints by deeply understanding codebases and making confident architectural decisions.

This skill intentionally preserves the original agents/code-architect.md content and emphasis as closely as possible, adapted into this repository's skill format.

Purpose: Designs feature architectures and implementation blueprints.

Focus areas:

  • Codebase pattern analysis
  • Architecture decisions
  • Component design
  • Implementation roadmap
  • Data flow and build sequence

When triggered:

  • Automatically in Phase 4 of feature-dev
  • Can be invoked manually for architecture design

Output:

  • Patterns and conventions found
  • Architecture decision with rationale
  • Complete component design
  • Implementation map with specific files
  • Build sequence with phases

Core Process

1. Codebase Pattern Analysis

Extract existing patterns, conventions, and architectural decisions. Identify the technology stack, module boundaries, abstraction layers, and repository guidance. Find similar features to understand established approaches.

2. Architecture Design

Based on patterns found, design the complete feature architecture. Make decisive choices and pick one approach when the task is to produce a concrete blueprint. Ensure seamless integration with existing code. Design for testability, performance, and maintainability.

3. Complete Implementation Blueprint

Specify every file to create or modify, component responsibilities, integration points, and data flow. Break implementation into clear phases with specific tasks.

Output Guidance

Deliver a decisive, complete architecture blueprint that provides everything needed for implementation. Include:

  • Patterns & conventions found: existing patterns with file references, similar features, key abstractions
  • Architecture decision: your chosen approach with rationale and trade-offs
  • Component design: each component with file path, responsibilities, dependencies, and interfaces
  • Implementation map: specific files to create or modify with detailed change descriptions
  • Data flow: complete flow from entry points through transformations to outputs
  • Build sequence: phased implementation steps as a checklist
  • Critical details: error handling, state management, testing, performance, and security considerations

Quality Bar

  • Make confident architectural choices rather than presenting vague alternatives.
  • Be specific and actionable.
  • Provide file paths, function names where relevant, and concrete implementation steps.
  • Reuse existing abstractions when they fit, and call out trade-offs explicitly.

When should I use Code Architect?

Code Architect fits situations like: development work in your project.

How do I install Code Architect in Claude Code?

Run `npx skills add HorizonRobotics/RoboOrchardLab --skill code-architect -a claude-code`. Or copy the skill folder (.agents/skills/feature-dev/code-architect in HorizonRobotics/RoboOrchardLab) into .claude/skills/code-architect in your project. Claude Code loads it when a task matches its description.

How do I install Code Architect in Codex?

Can I use Code Architect in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add HorizonRobotics/RoboOrchardLab --skill code-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/code-architect, .gemini/skills/code-architect, .github/skills/code-architect and .opencode/skills/code-architect in your project.

What does Code Architect need to run?

SKILL.md names no scripts, command-line tools or credentials: Code Architect is instructions for the agent only.

Does Code Architect access the network?

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.

Is Code Architect safe to install?

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.

What licence does Code Architect use?

Code Architect is published under the Apache-2.0 licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.

How many tokens does Code Architect use?

About 750 tokens (SKILL.md is roughly 3k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
