Clean: nothing in its files matched our rules. We read 1 file in the folder on 2026-09-28.

No findings.

Install the onboard skill

A skill is a folder. Copy it into your agent's skills folder and the agent loads it when the task matches its description.

git clone --depth 1 https://github.com/Donchitos/Claude-Code-Game-Studios.git /tmp/Claude-Code-Game-Studios
mkdir -p ~/.claude/skills
cp -r /tmp/Claude-Code-Game-Studios/.claude/skills/onboard ~/.claude/skills/onboard
available in every project

In the Claude apps, zip the folder and upload it from the Skills settings. The folder on GitHub

Automation mode: Resolve modes.automation (project.local.yaml → project.yaml → default collaborative). Every AskUserQuestion call and every file write follows .claude/docs/automation-modes.md (collaborative asks always · guided major-only · autonomous logs and proceeds; automationalwaysask categories always prompt).

Insufficient input — check this before producing any report

If the inputs this skill needs do not exist, the answer is "could not run" — not a filled-in report. Check first, and stop if the check fails.

NOT ASSESSED — NO DATA. Do not estimate it, do not infer it from an adjacent artifact, and do not leave a mandated cell to be filled by whoever reads the template next.

  2. If any input required for a section is ABSENT, that section is

NOT ASSESSED — NO DATA as the whole verdict, naming what was missing and which skill produces it.

  1. If every required input is ABSENT, stop and report

A verdict of NOT ASSESSED is a success. It is the correct, useful answer to "what does the data say?" when there is no data. The failure mode this prevents is specific and has been observed in practice: report templates whose verdict enum had no "could not run" state produced false clean passes — an asset audit returning COMPLIANT on a project with no assets and no standards, and a performance profile reporting ">99% headroom against a 16.67ms budget" with zero profiler data and no budget ever set.

Absence of evidence is never evidence of absence. A scan that finds no matches because there are no files to scan has not verified anything. Say which of the two happened — a reader cannot tell from a green result.

Phase 1: Load Project Context

Read CLAUDE.md for project overview and standards.

Read the relevant agent definition from .claude/agents/ if a specific role is specified.

Phase 2: Scan Relevant Area

  • For programmers: scan the code root (resolve per .claude/docs/code-root-resolution.md) for architecture, patterns, key files
  • For designers: scan design/ for existing design documents
  • For narrative: scan design/narrative/ for world-building and story docs
  • For QA: scan tests/ for existing test coverage
  • For production: scan production/ for current sprint and milestone

Read recent changes (git log if available) to understand current momentum.

Phase 3: Generate Onboarding Document

# Onboarding: [Role/Area]

## Project Summary
[2-3 sentence summary of what this game is and its current state]

## Your Role
[What this role does on this project, key responsibilities, who you report to]

## Project Architecture
[Relevant architectural overview for this role]

### Key Directories
| Directory | Contents | Your Interaction |
|-----------|----------|-----------------|

### Key Files
| File | Purpose | Read Priority |
|------|---------|--------------|

## Current Standards and Conventions
[Summary of conventions relevant to this role from CLAUDE.md and agent definition]

## Current State of Your Area
[What has been built, what is in progress, what is planned next]

## Current Sprint Context
[What the team is working on now and what is expected of this role]

## Key Dependencies
[What other roles/systems this role interacts with most]

## Common Pitfalls
[Things that trip up new contributors in this area]

## First Tasks
[Suggested first tasks to get oriented and productive]

1. [Read these documents first]
2. [Review this code/content]
3. [Start with this small task]

## Questions to Ask
[Questions the new contributor should ask to get fully oriented]

Phase 4: Save Document

Present the onboarding document to the user.

Ask: "May I write this to production/onboarding/onboard-[role]-[date].md?"

If yes, write the file, creating the directory if needed.

Phase 5: Next Steps

Verdict: COMPLETE — onboarding document generated.

  • Share the onboarding doc with the new contributor before their first session.
  • Run /sprint-status to show the new contributor current progress.
  • Run /help if the contributor needs guidance on what to work on next.
