explore-module

A guided investigation of one code module, covering its structure, entry points, dependencies, users, tests, and documentation. A module is a part of a codebase that groups related functionality.

In plain words
What is it for?
Use it to map a module's files and exports, trace what it imports and what imports it, locate tests, and review its documentation.
Why use it?
It reduces the time needed to understand unfamiliar code and makes hidden dependencies or circular imports easier to find. This is useful before modifying or debugging the module.

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.

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

explore-module 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 2d 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.

Module Explorer

Please help me deeply understand this module: $MODULE_PATH

Exploration depth: ${DEPTH:-3} Focus areas: ${FOCUS:-all aspects}

Module Analysis

  1. Get module overview:

    # Show module structure
    ch ctx focus "$MODULE_PATH" ${DEPTH:-3}
    
    # List all files
    find "$MODULE_PATH" -type f -name "*.${EXT:-js|ts|py}" | head -20
    
  2. Understand module boundaries:

    # Find entry points
    chs find-file "index.*" "$MODULE_PATH"
    
    # Look for main exports
    chs find-code "export|module.exports" "$MODULE_PATH"
    
  3. Trace dependencies:

    # What does this module import?
    ch cr imports-of "$MODULE_PATH/index.${EXT:-js}"
    
    # Generate dependency tree
    ch cr dependency-tree "$MODULE_PATH"
    
    # Check for circular dependencies
    ch cr circular "$MODULE_PATH"
    
  4. Find who uses this module:

    # Who imports this module?
    ch cr imported-by "$MODULE_PATH"
    
    # Search for direct references
    MODULE_NAME=$(basename "$MODULE_PATH")
    chs find-code "from.*$MODULE_NAME|import.*$MODULE_NAME"
    
  5. Locate tests:

    # Find test files
    chs find-file "*.test.*|*.spec.*" "$MODULE_PATH"
    
    # Find tests in other locations
    chs find-code "$MODULE_NAME" --include "*.test.*"
    
  6. Check documentation:

    # Find docs
    chs find-file "*.md" "$MODULE_PATH"
    
    # Look for inline documentation
    chs find-code "^\\s*\\*|^\\s*/\\*\\*|@param|@returns" "$MODULE_PATH"
    
  7. Analyze code quality:

    # Check complexity
    ch cq large-files 200 "$MODULE_PATH"
    
    # Find TODOs
    ch cq todos "$MODULE_PATH"
    

Key Questions

  1. Architecture:

    • What is the module's primary responsibility?
    • How does it fit into the overall architecture?
    • Are there clear boundaries and interfaces?
  2. Dependencies:

    • What are the external dependencies?
    • Are there any concerning coupling issues?
    • Could this module be easily extracted/reused?

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.

explore-module is a command published in the GitHub repository cassler/awesome-claude-code-setup (267 stars, last pushed 4mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 637 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
