onboard

onboard is a skill for Claude Code from SyloRei/claude-godmode. It costs 42 tokens per session (3,019 once invoked), scanned A, original, MIT.

A read-only orientation tool for an unfamiliar codebase, meaning a software project’s source files and supporting configuration. It creates a cheatsheet covering the architecture, entry points, conventions, file locations, and how to run and test the project.

In plain words
What is it for?
Use it when joining or exploring a repository, especially before starting a larger implementation mission.
Why use it?
It reduces the time spent figuring out how a repository is organised and how its checks work before making a plan. It reports findings without editing the code.

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

onboard 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.

How it starts

The opening of the file, as written. The whole thing — 259 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Onboard

Orient yourself in an unfamiliar codebase fast. Produces a structured cheatsheet — architecture overview, entry points, key conventions, where-things-live, and how-to-run/test — by spawning @researcher for cited findings. Runs read-only: it observes and reports, it never edits.

This is the recommended orientation step for an unfamiliar repo, run before /mission. The cheatsheet sharpens the project charter and roadmap that /mission captures.


Auto Mode

When ## Auto Mode Active is present in context: do not ask clarifying questions. Orient using reasonable defaults (full repo unless a subsystem is named), surface scope assumptions inline, present the cheatsheet, and offer to persist it rather than blocking on it. Treat user course-corrections as normal input.


The Job

Investigate systematically, then present a structured cheatsheet. Spawn @researcher for cited findings and parallel deep dives — never explore the codebase inline when @researcher can do it in parallel.


Process

1. Project Detection (aligns with the Auto-Detection rules in rules/godmode-coding.md)

  • Language and framework
  • Package manager and build system
  • Test runner and coverage setup
  • Linter and formatter
  • Typechecker
  • CI/CD configuration
  • Monorepo or single package
  • Deployment target (serverless, containers, static)

2. Architecture Map

  • Directory structure and organization pattern
  • Entry points (main, index, app, handler)
  • Key abstractions: core types, interfaces, base classes
  • Internal dependency graph
  • External dependencies and their roles

3. Convention Analysis

  • Naming conventions (files, variables, functions, classes)
  • Error handling patterns
  • State management approach
  • Data flow patterns
  • Testing patterns and coverage

4. Code Standards (prescriptive — distinct from Convention Analysis)

Where Convention Analysis above describes the patterns it observes, Code Standards prescribes the DO / DON'T rules the codebase has already established for itself. This step always runs — whether its findings end up persisted is decided later in Saving Results, not here.

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.

onboard is a skill published in the GitHub repository SyloRei/claude-godmode (3 stars, last pushed 3mo ago), licensed MIT. It adds 42 tokens to every session and 3,019 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 2026-08-31.
