onboarding

onboarding is a command for Claude Code from mort-lab/excel-mcp. It costs 0 tokens per session (649 once invoked), scanned A, a copy of onboarding, MIT.

A command that analyzes a software project for a new developer. It covers the project’s purpose, technology, repository structure, setup process, important components, testing, and production builds.

In plain words
What is it for?
Use it to explain a project’s architecture, dependencies, directories, entry points, configuration, local setup, tests, and build process.
Why use it?
It gathers the information a newcomer needs in one onboarding report instead of requiring them to discover the codebase and setup steps alone.

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

onboarding 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 3d 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 — 93 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Please perform a comprehensive onboarding analysis for a new developer joining this project. Execute the following steps:

1. Project Overview

First, analyze the repository structure and provide:

  • Project name, purpose, and main functionality
  • Tech stack (languages, frameworks, databases, tools)
  • Architecture pattern (MVC, microservices, etc.)
  • Key dependencies and their purposes

2. Repository Structure

Map out the codebase organization:

  • List all top-level directories with their purposes
  • Identify where different types of code live (models, controllers, utils, tests)
  • Highlight any non-standard or unique organizational patterns
  • Note any monorepo structures or submodules

3. Getting Started

Create step-by-step setup instructions:

  • Prerequisites (required software, versions)
  • Environment setup commands
  • How to install dependencies
  • Configuration files that need to be created/modified
  • How to run the project locally
  • How to run tests
  • How to build for production

4. Key Components

Identify and explain the most important files/modules:

  • Entry points (main.js, index.py, app.tsx, etc.)
  • Core business logic locations
  • Database models/schemas
  • API endpoints or routes
  • Configuration management
  • Authentication/authorization implementation

5. Development Workflow

Document the development process:

  • Git branch naming conventions
  • How to create a new feature
  • Testing requirements
  • Code style/linting rules
  • PR process and review guidelines
  • CI/CD pipeline overview

6. Architecture Decisions

Identify important patterns and decisions:

  • Design patterns used and why
  • State management approach
  • Error handling strategy
  • Logging and monitoring setup
  • Security measures
  • Performance optimizations

7. Common Tasks

Provide examples for frequent development tasks:

  • How to add a new API endpoint
  • How to create a new database model
  • How to add a new test
  • How to debug common issues
  • How to update dependencies

8. Potential Gotchas

List things that might trip up new developers:

  • Non-obvious configurations
  • Required environment variables
  • External service dependencies
  • Known issues or workarounds
  • Performance bottlenecks
  • Areas of technical debt

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.

onboarding is a command published in the GitHub repository mort-lab/excel-mcp (5 stars, last pushed 26d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 649 tokens. A static security scan graded it A with 0 findings. It is 100% identical to onboarding, differing in 206 lines, and is treated as a copy.
