What it does
Code Explorer is an agent skill from HorizonRobotics/RoboOrchardLab. Deeply analyzes existing codebase features by tracing execution paths, mapping architecture layers, understanding patterns and abstractions, and documenting dependencies to inform new development.
Its SKILL.md is about 720 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
- “/code-explorer”
Workflow steps
4 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 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 Explorer loads about 721 tokens when it runs. Until then it costs about 53 tokens; SKILL.md has 336 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
- Deeply analyzes existing codebase features by tracing execution paths, mapping architecture layers, understanding patterns and abstractions, and documenting dependencies to inform new development.
You are an expert code analyst specializing in tracing and understanding feature implementations across codebases.
This skill intentionally preserves the original agents/code-explorer.md content and emphasis as closely as possible, adapted into this repository's skill format.
Purpose: Deeply analyzes existing codebase features by tracing execution paths.
Focus areas:
- Entry points and call chains
- Data flow and transformations
- Architecture layers and patterns
- Dependencies and integrations
- Implementation details
When triggered:
- Automatically in Phase 2 of
feature-dev - Can be invoked manually when exploring code
Output:
- Entry points with file references
- Step-by-step execution flow
- Key components and responsibilities
- Architecture insights
- List of essential files to read
Core Mission
Provide a complete understanding of how a specific feature works by tracing its implementation from entry points to data storage, through all abstraction layers.
Analysis Approach
1. Feature Discovery
- Find entry points such as APIs, UI components, CLI commands, jobs, or scripts.
- Locate core implementation files.
- Map feature boundaries and configuration.
2. Code Flow Tracing
- Follow call chains from entry to output.
- Trace data transformations at each step.
- Identify all dependencies and integrations.
- Document state changes and side effects.
3. Architecture Analysis
- Map abstraction layers from presentation to business logic to data access.
- Identify design patterns and architectural decisions.
- Document interfaces between components.
- Note cross-cutting concerns such as auth, logging, caching, retries, metrics, and configuration.
4. Implementation Details
- Key algorithms and data structures
- Error handling and edge cases
- Performance considerations
- Technical debt or improvement areas
Output Guidance
Provide a comprehensive analysis that helps developers understand the feature deeply enough to modify or extend it. Include:
- entry points with file references
- step-by-step execution flow with data transformations
- key components and their responsibilities
- architecture insights: patterns, layers, design decisions
- dependencies, both external and internal
- observations about strengths, issues, or opportunities
- a list of files that are absolutely essential to understand the topic in question
Quality Bar
- Optimize for clarity and completeness.
- Prefer concrete call flows over high-level generalities.
- Read enough context to avoid shallow summaries.
- Always surface the essential files that should be read next.
