tomevault-io SE Dev Plugin Skill
Plugin development for Space Engineers version 1.
⚠️ CRITICAL: Commands run in a UNIX shell (busybox), NOT Windows CMD. Use bash syntax!
Examples:
- ✅
test -f file.txt && echo exists - ✅
ls -la | head -10 - ❌
if exist file.txt (echo exists)- This will NOT work
Actions:
- prepare: Run the one-time preparation (Prepare.bat)
- bash: Run UNIX shell commands via busybox
- search: Search plugin code using
search_plugins.py
Routing Decision
Check these patterns in order - first match wins:
| Priority | Pattern | Example | Route |
|---|---|---|---|
| 1 | Empty or bare invocation | se-dev-plugin |
Show this help |
| 2 | Prepare keywords | se-dev-plugin prepare, se-dev-plugin setup, se-dev-plugin init |
prepare |
| 3 | Bash/shell keywords | se-dev-plugin bash, se-dev-plugin grep, se-dev-plugin cat |
bash |
| 4 | Search keywords | se-dev-plugin search, se-dev-plugin find class, se-dev-plugin lookup |
search |
Getting Started
⚠️ CRITICAL: Before running ANY commands, read CommandExecution.md to avoid common mistakes that cause command failures.
If the Prepare.DONE file is missing in this folder, you MUST run the one-time preparation steps first. See the prepare action.
Essential Documentation
- CommandExecution.md - ⚠️ READ THIS FIRST - How to run commands correctly on Windows

Harmony Patching Documentation
Progressive documentation for Harmony patching (start with basics, then read advanced topics as needed):
- Patching.md - Start here: patch types, prefix/postfix basics, common patterns
- PatchInjections.md - Special parameters:
__instance,__result,___fields,__state - AccessTools.md - Reflection utilities for finding methods, fields, and types
- TranspilerPatching.md - IL-level patching for complex modifications
- PatchingSpecialCases.md - Finalizers, reverse patches, auxiliary methods, priority
- PreloaderPatching.md - Pre-JIT patching (Mono.Cecil, client only)
Plugin Distribution
Plugins are released exclusively on the PluginHub. All plugins must be open source, since they are compiled on the player's machine from the GitHub source revision identified by its PluginHub registration. Plugins are reviewed for safety and security on submission, but only on a best effort basis, without any legal guarantees. Plugins are running native code and can do anything.
Use the se-dev-game-code skill to search the game's decompiled code. You will need this to
understand how the game's internals work and how to interface with it and patch it properly.

Plugin Code Search
Search the source code of plugins from PluginHub for examples and patterns:
# List available plugins
uv run list_plugins.py
uv run list_plugins.py --search "camera"
# Download a plugin's source code (use EXACT name from list)
uv run download_plugin_source.py "Tool Switcher"
# Index downloaded plugins (automatic after download)
uv run index_plugins.py
# Search plugin code
uv run search_plugins.py class declaration Plugin
uv run search_plugins.py method signature Patch
# Count results before viewing (useful for large result sets)
uv run search_plugins.py class usage Plugin --count
# Limit number of results
uv run search_plugins.py class usage IPlugin --limit 20
The PluginHub contains descriptions of all available plugins. Download sources for plugins that may help with your task, then index and search them.
See search action for complete documentation.
