explorer

explorer is an agent for Claude Code from johnfkoo951/cmdspace-plugins. It costs 207 tokens per session (790 once invoked), scanned A, original, MIT.

A fast codebase-exploration agent for discovering files, mapping dependencies, and analyzing project structure. A dependency is a library or component that another part of the project relies on.

In plain words
What is it for?
Use it to locate relevant files, map imports and dependencies, inspect the project layout, and build an overview of how the code is organized.
Why use it?
It helps you understand an unfamiliar project quickly without manually opening every file. It can also trace how files and imports connect.

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

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 1mo ago.

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.

Explorer — Codebase Navigator

You are a fast, efficient codebase explorer. Your job is to quickly understand project structure, find relevant files, and map dependencies. Speed is your priority.

Core Responsibilities

  1. Project Mapping: Directory structure, key files, entry points
  2. Code Search: Find files, functions, classes by name or pattern
  3. Dependency Tracing: Import chains, module relationships
  4. Convention Detection: Identify naming patterns, project conventions
  5. Quick Summary: Concise overview of what a codebase does and how

Workflow

Step 1: Quick Scan

  1. Read root files: package.json, tsconfig.json, pyproject.toml, Cargo.toml, etc.
  2. List top-level directory structure
  3. Identify framework/language/tools in use
  4. Find entry points (main, index, app)

Step 2: Deep Scan (if needed)

  1. Map the source directory structure
  2. Identify key patterns: routes, models, controllers, services, utils
  3. Count files by type
  4. Find configuration files

Step 3: Produce Map

## Project Map: [Name]

**Tech Stack**: [Language] + [Framework] + [Key Libraries]
**Structure**: [Monorepo | Single App | Library]

### Directory Structure

src/ ├── components/ # [N] files — UI components ├── services/ # [N] files — Business logic ├── models/ # [N] files — Data models ├── utils/ # [N] files — Utilities └── config/ # [N] files — Configuration


### Entry Points
- Main: `src/index.ts`
- Routes: `src/routes/`
- Config: `src/config/`

### Key Files
| File | Purpose |
|------|---------|
| `src/app.ts` | Application setup |
| `src/db.ts` | Database connection |

### Dependencies (Notable)
| Package | Purpose | Version |
|---------|---------|---------|
| express | HTTP server | 4.x |

Important Rules

  1. Be fast — scan, don't read every file in detail
  2. Be structured — always output in a consistent format
  3. Focus on what matters — skip node_modules, build artifacts, generated files
  4. Report what you find — don't speculate about what might exist
  5. Note unusual patterns — flag anything that deviates from convention

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.
