Continuous scanner CI not detected
This plugin remains listed. Its overall trust score is reduced by 10% because security checks are not maintained in the source repository's CI.
Optional: maintain the scanner in the source repository's CI to receive the full trust score. Listing does not require that change.
README badge not detected
Plugin owners can add the HOL badge to the repository README from Guard Plugins. Distribution, not security evidence. It adds a 2% engagement adjustment to the overall trust score and never changes the security result.

Install Guidance
Install in Claude Code
Install through the Claude Code plugin marketplace.
Optional: install HOL Guard for Claude Code first, so it can check this plugin's tools on your machine before Claude Code uses them.
- 1
Add the marketplace
Run this inside a Claude Code session. It registers the marketplace manifest shipped at the repository root. If the repository ships none, add the generated entry from the Advanced section below first.
claude code - 2
Find the marketplace and plugin names
The install id is <plugin-entry>@<marketplace-name>, and the marketplace name is declared inside the manifest — it can differ from the repository name. List registered marketplaces to read both names.
shell - 3
Install the plugin
Substitute the plugin entry name and the marketplace name shown by the previous step.
claude code
Did setup work in Claude Code?
No setup reports for Claude Code yet. Self-reported by signed-in visitors. Copying a command is not counted, and most installs are never reported.
Attested installs: Fewer than 10 attested installs of this plugin in week 2026-W43, so no number is shown. Counted from opt-in HOL Guard install reports, once per machine and runtime, and never mixed with the answers above. How install reports work.

Skills
7 SKILL.md files ship with this plugin. Preview, copy, or download each one, then install them with the Skills CLI.
skills/debugging-code/SKILL.md
Use for debugger-driven runtime root-cause analysis in Rider-supported solutions and projects, including .NET/C#, F#, VB, C++, Unity, Unreal Engine, and other GameDev or mixed-language projects. Trigger when runtime state or control-flow evidence is needed — actual values, branch taken, call order, thread context, whether execution reaches a chosen line — and cannot be derived confidently from source or logs; when pinning the relevant path would otherwise mean reading many files or tracing a deep call chain; or on an explicit request to debug, set breakpoints, step, or inspect runtime values. Do not use for compile-time or syntax errors, source-obvious bugs, failures already pinpointed by logs/tests, or code merely named debug/Debugger.
SKILL.md content is not in this snapshot. Open the raw file to copy it from the source repository.
skills/finding-tests/SKILL.md
Locates existing tests for a given C# class and method using the test coverage data supplied by IDE. Triggers ONLY for C# production code (`.cs` files in a Rider .NET solution) when generating new tests, adding test coverage, finding existing tests, or when the user mentions uncovered lines, test files, or test suites. Must be used before writing or editing C# test code when finding already existing tests is necessary. Do NOT invoke for non-C# languages — the underlying tool only understands C# symbols and will not return useful results.
SKILL.md content is not in this snapshot. Open the raw file to copy it from the source repository.
skills/navigating-code/SKILL.md
Use when you must know where a symbol is used or implemented in a solution open in Rider — .NET/C#, F#, VB, C++, Unity, Unreal Engine, XAML, Razor, or mixed-language projects. Trigger before changing a method, property, field, type or interface, when you trace callers, when you look for the classes that implement an interface or the overrides of a virtual member, and whenever you would otherwise grep for an identifier. Do not use for plain text (strings, comments, config keys, log messages) or to find a file by name.
SKILL.md content is not in this snapshot. Open the raw file to copy it from the source repository.
skills/refactoring-code/SKILL.md
Use when semantic refactoring is needed in Rider-supported solutions and projects, including .NET/C#, F#, VB, C++, Unity, Unreal Engine, XAML, Razor, and other GameDev or mixed-language projects. Trigger when edits must update declarations and usages across IDE-resolved references — rename symbols, move types or namespaces, safe-delete unused code, extract interface/base class/method, change signatures, or reorganize namespaces. Do not use for file-only moves, config keys, strings, comments, prose-only edits, generated output, or logic changes with unchanged names/signatures.
SKILL.md content is not in this snapshot. Open the raw file to copy it from the source repository.
skills/ue-code-authoring/SKILL.md
Use when writing or modifying Unreal Engine C++ — classes, actors, components, subsystems, interfaces, ability-system (GAS) code, module dependencies, reflected UPROPERTY/UFUNCTION API, native gameplay tags, and testable gameplay behavior — in a project open in JetBrains Rider. Source changes go through Read/Grep/Glob/Edit/Write; Rider supplies symbol search, code analysis, formatting, and builds through its MCP execute_tool. Do not use for Blueprint-only tasks or editor automation with no C++ authoring.
SKILL.md content is not in this snapshot. Open the raw file to copy it from the source repository.
skills/ue-live-debugging/SKILL.md
Use when debugging UE C++ crashes, runtime bugs, or unexpected behavior with Rider MCP available. Value over bash/grep: analyze_calls traces C++ call hierarchies (ReSharper backend); get_file_problems surfaces IDE-detected issues; get_symbol_info confirms API contracts; xdebug_set_breakpoints sets live breakpoints; ue_execute_python queries live PIE state. DO NOT TRIGGER for: pure build errors with no runtime component, net-new feature work, Blueprint-only work. When Rider MCP is unavailable, runs in reduced mode — Bash/Grep only, IDE diagnostics skipped.
SKILL.md content is not in this snapshot. Open the raw file to copy it from the source repository.
skills/ue-test-authoring/SKILL.md
Use when writing or modifying Unreal Engine automated tests — Automation (IMPLEMENT_SIMPLE_AUTOMATION_TEST, DEFINE_SPEC), CQTest, Functional, Gauntlet, LowLevel/Catch2 — along with test modules and the Build.cs dependencies they need, in a project open in JetBrains Rider. Test source goes through Read/Grep/Glob/Edit/Write; Rider supplies symbol lookup for the API under test, registration and include diagnostics, formatting, and builds through its MCP tools. Do not use for Blueprint-only testing, or for diagnosing an existing test failure that needs no test code change.
