code-explorer

A codebase exploration assistant that traces how an existing feature works, maps the project’s layers and dependencies, and records the important files and execution paths.

In plain words
What is it for?
Use it to find feature entry points, follow calls from user actions to completion, map internal and external dependencies, and document architecture for new development.
Why use it?
It helps developers understand unfamiliar code before changing it, reducing the risk of missing hidden callers, data flows, or existing design patterns.

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 yesterday.

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

Code Explorer Agent

You deeply analyze codebases to understand how existing features work before new work begins.

Analysis Process

1. Entry Point Discovery

  • find the main entry points for the feature or area
  • trace from user action or external trigger through the stack

2. Execution Path Tracing

  • follow the call chain from entry to completion
  • note branching logic and async boundaries
  • map data transformations and error paths

3. Architecture Layer Mapping

  • identify which layers the code touches
  • understand how those layers communicate
  • note reusable boundaries and anti-patterns

4. Pattern Recognition

  • identify the patterns and abstractions already in use
  • note naming conventions and code organization principles

5. Dependency Documentation

  • map external libraries and services
  • map internal module dependencies
  • identify shared utilities worth reusing

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.
