wiki-onboarding

wiki-onboarding is a skill for Claude Code from ratnesh-maurya/cursor-claude-personas. It costs 36 tokens per session (927 once invoked), scanned A, original, MIT.

An onboarding guide generator that creates two views of a codebase: an architectural deep dive for senior engineers and a step-by-step walkthrough for new contributors.

In plain words
What is it for?
Use it to create onboarding documentation and getting-started guides tailored to different levels of engineering experience.
Why use it?
It reduces the time needed to understand an unfamiliar repository and explains both how the system is structured and how to start contributing.

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

wiki-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 9d 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.

Wiki Onboarding Guide Generator

Generate two complementary onboarding documents that together give any engineer — from newcomer to principal — a complete understanding of a codebase.

When to Activate

  • User asks for onboarding docs or getting-started guides
  • User runs /deep-wiki:onboard command
  • User wants to help new team members understand a codebase

Language Detection

Scan the repository for build files to determine the primary language for code examples:

  • package.json / tsconfig.json → TypeScript/JavaScript
  • *.csproj / *.sln → C# / .NET
  • Cargo.toml → Rust
  • pyproject.toml / setup.py / requirements.txt → Python
  • go.mod → Go
  • pom.xml / build.gradle → Java

Guide 1: Principal-Level Onboarding

Audience: Senior/staff+ engineers who need the "why" behind decisions.

Required Sections

  1. System Philosophy & Design Principles — What invariants does the system maintain? What were the key design choices and why?
  2. Architecture Overview — Component map with Mermaid diagram. What owns what, communication patterns.
  3. Key Abstractions & Interfaces — The load-bearing abstractions everything depends on
  4. Decision Log — Major architectural decisions with context, alternatives considered, trade-offs
  5. Dependency Rationale — Why each major dependency was chosen, what it replaced
  6. Data Flow & State — How data moves through the system (traced from actual code, not guessed)
  7. Failure Modes & Error Handling — What breaks, how errors propagate, recovery patterns
  8. Performance Characteristics — Bottlenecks, scaling limits, hot paths
  9. Security Model — Auth, authorization, trust boundaries, data sensitivity
  10. Testing Strategy — What's tested, what isn't, testing philosophy
  11. Operational Concerns — Deployment, monitoring, feature flags, configuration
  12. Known Technical Debt — Honest assessment of shortcuts and their risks

Rules

  • Every claim backed by (file_path:line_number) citation
  • Minimum 3 Mermaid diagrams (architecture, data flow, dependency graph)
  • All Mermaid diagrams use dark-mode colors (see wiki-vitepress skill)
  • Focus on WHY decisions were made, not just WHAT exists

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.

wiki-onboarding is a skill published in the GitHub repository ratnesh-maurya/cursor-claude-personas (8 stars, last pushed 5mo ago), licensed MIT. It adds 36 tokens to every session and 927 once invoked, about $0.0002 per session on Opus 5. 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 2026-09-03.
