What it does
Godot E2E is an agent skill from RandallLiuXin/GodotMaker. Write and run E2E (end-to-end) game tests using the godot-e2e framework. Python controls a live Godot game over TCP — Locator-based semantic queries, expect() auto-retry assertions, and engine log capture make failures self-diagnosing. Use this skill whenever you need to: - Test actual gameplay: player movement, collisions, scoring, scene transitions - Verify UI interactions: button clicks, label text, menu navigation - Write integration tests that run the real game (not mocked unit tests) - Debug E2E test…
Its SKILL.md is about 3.9k tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files, including reference files (for example `references/api-reference.md` and `references/testing-patterns.md`).
It sits in Testing & QA, covering Game development, End-to-end testing and Integration testing. It works with Godot and Python. The repository describes itself as: Autonomous text-to-game pipeline for Godot, powered by Claude Code,Codex,Opencode.
When your agent uses it
- You need to: - Test actual gameplay: player movement
- Scene transitions - Verify UI interactions: button clicks
- Menu navigation - Write integration tests that run the real game (not mocked unit tests) - Debug E2E test failures
- Set up E2E test infrastructure Triggers: E2E test
Example prompts
- “E2E test”
- “end-to-end test”
- “gameplay test”
- “/godot-e2e”
Requirements
- Python 3
Workflow steps
3 steps, taken from the first numbered list in SKILL.md.
- At least 1 user action — input_action, press_action, click, Locator.click(), or call that triggers gameplay
- At least 1 state-change assertion — verify a property CHANGED (not just that a node exists). Prefer expect(...) matchers over manual…
- No pure existence tests — node_exists / Locator.exists() may serve as a precondition, but NEVER as the only assertion
What it can do on your machine
Read from SKILL.md and the folder at commit 1d4702c. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
pytest
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Godot E2E loads about 3.9k tokens when it runs, and up to ~19k if it reads all its reference files. Until then it costs about 194 tokens; SKILL.md has 1,219 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 1,219 words (~3,899 tokens).
