repo-scan

repo-scan is a skill for Claude Code, Codex from majiang213/OpenClaw-MAS. It costs 36 tokens per session (826 once invoked), scanned A, a copy of repo-scan, MIT.

A source-code auditing tool that examines files across C++, Android, iOS, and web projects and labels what belongs to the project, came from elsewhere, or is a build artifact.

In plain words
What is it for?
Use it to map a legacy codebase, find duplicate or unused material, detect embedded libraries, and support decisions about reorganizing a monorepo, a repository containing multiple related projects.
Why use it?
It gives teams a structural view of a large codebase before refactoring, especially when third-party code is embedded directly in source files.

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

repo-scan 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 8d 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.

How it starts

The opening of the file, as written. The whole thing — 79 lines — stays where its author put it; the contents beside it link to each section on GitHub.

repo-scan

Every ecosystem has its own dependency manager, but no tool looks across C++, Android, iOS, and Web to tell you: how much code is actually yours, what's third-party, and what's dead weight.

When to Use

  • Taking over a large legacy codebase and need a structural overview
  • Before major refactoring — identify what's core, what's duplicate, what's dead
  • Auditing third-party dependencies embedded directly in source (not declared in package managers)
  • Preparing architecture decision records for monorepo reorganization

Installation

# Fetch only the pinned commit for reproducibility
mkdir -p ~/.claude/skills/repo-scan
git init repo-scan
cd repo-scan
git remote add origin https://github.com/haibindev/repo-scan.git
git fetch --depth 1 origin 2742664
git checkout --detach FETCH_HEAD
cp -r . ~/.claude/skills/repo-scan

Core Capabilities

Capability Description
Cross-stack scanning C/C++, Java/Android, iOS (OC/Swift), Web (TS/JS/Vue) in one pass
File classification Every file tagged as project code, third-party, or build artifact
Library detection 50+ known libraries (FFmpeg, Boost, OpenSSL…) with version extraction
Four-level verdicts Core Asset / Extract & Merge / Rebuild / Deprecate
HTML reports Interactive dark-theme pages with drill-down navigation
Monorepo support Hierarchical scanning with summary + sub-project reports

Analysis Depth Levels

Level Files Read Use Case
fast 1-2 per module Quick inventory of huge directories
standard 2-5 per module Default audit with full dependency + architecture checks
deep 5-10 per module Adds thread safety, memory management, API consistency
full All files Pre-merge comprehensive review

How It Works

  1. Classify the repo surface: enumerate files, then tag each as project code, embedded third-party code, or build artifact.
  2. Detect embedded libraries: inspect directory names, headers, license files, and version markers to identify bundled dependencies and likely versions.
  3. Score each module: group files by module or subsystem, then assign one of the four verdicts based on ownership, duplication, and maintenance cost.
  4. Highlight structural risks: call out dead-weight artifacts, duplicated wrappers, outdated vendored code, and modules that should be extracted, rebuilt, or deprecated.
  5. Produce the report: return a concise summary plus the interactive HTML output with per-module drill-down so the audit can be reviewed asynchronously.

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.
