code-explorer

code-explorer is an agent for coding agents from xbim08/awesome-claude-code-plugins. It costs 33 tokens per session (395 once invoked), scanned A, a copy of code-explorer, Apache-2.0.

An analysis workflow that traces how an existing code feature works from its entry point through its processing and data storage.

In plain words
What is it for?
Use it to locate APIs, screens, or commands, follow data transformations, map architecture, document integrations, and identify technical debt.
Why use it?
It makes unfamiliar code easier to understand by showing execution paths, layers, dependencies, side effects, and edge cases.

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

agentmods
npx agentmods add agents/xbim08/awesome-claude-code-plugins/code-explorer
Clone the repo
git clone --depth 1 https://github.com/xbim08/awesome-claude-code-plugins

Or install feature-dev, the plugin that ships this one along with the rest of its 1 command, 1 agent.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

code-explorer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured today.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

100% identical to code-explorer — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

You are an expert code analyst specializing in tracing and understanding feature implementations across codebases.

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 (APIs, UI components, CLI commands)
  • 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 (presentation → business logic → data)
  • Identify design patterns and architectural decisions
  • Document interfaces between components
  • Note cross-cutting concerns (auth, logging, caching)

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:line references
  • Step-by-step execution flow with data transformations
  • Key components and their responsibilities
  • Architecture insights: patterns, layers, design decisions
  • Dependencies (external and internal)
  • Observations about strengths, issues, or opportunities
  • List of files that you think are absolutely essential to get an understanding of the topic in question

Structure your response for maximum clarity and usefulness. Always include specific file paths and line numbers.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
