Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00054 | $0.01032 |
| Opus 5 | $0.00027 | $0.00516 |
| Sonnet 5 | $0.00011 | $0.00206 |
| Haiku 4.5 | $0.00005 | $0.00103 |
Grade A, and why
ue5-debug-validation 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 8d 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.
This is a copy
100% identical to ue5-debug-validation — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 109 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Quick Start
- Reproduce issue with minimal steps.
- Collect output log lines and relevant actor/asset state.
- Classify fault domain: data, Blueprint, C++, networking, or editor config.
UE5.7 API Anchors
- Core diagnostics anchors:
UE_LOG(...)ensure(...),ensureMsgf(...)check(...),checkf(...)
- Runtime debug output anchors:
UEngine::AddOnScreenDebugMessage(...)UKismetSystemLibrary::PrintString(...)
- Structured log review anchors:
FMessageLog::Info(...)FMessageLog::Warning(...)FMessageLog::Error(...)
- Asset/config verification anchors:
FAssetRegistryModule,IAssetRegistryGetAssetsByPath(...)GetDependencies(...),GetReferencers(...)
Debug Stage Contract
- Every debug task must define:
- reproducible scenario and expected vs observed behavior
- data capture set (logs, runtime state, asset/config snapshot)
- first bad transition candidate in the execution pipeline
- hypothesis list ranked by probability and verification cost
- fix validation and regression scope
- If any item is missing, diagnosis output is incomplete.
Workflow
1) Reproduce and Freeze Context
- Build a minimal deterministic repro with exact steps and preconditions.
- Capture map, actor setup, input sequence, and runtime mode.
- Define expected result and observed deviation.
2) Capture Signals
- Filter logs by relevant categories and timestamps around failure window.
- Add targeted debug markers (
UE_LOG, on-screen debug, or Blueprint print) if needed. - Capture relevant state snapshots at stage boundaries.
3) Validate Data and Assets
- Verify key assets/classes/config entries exist and resolve correctly.
- Check dependencies/referencers for missing or mismatched assets.
- Confirm runtime-loaded data matches expected environment.
4) Locate First Bad Transition
- Walk pipeline step-by-step and identify earliest divergence point.
- Separate root cause from downstream noise symptoms.
- Prioritize smallest fixable cause with highest confidence.
What ships with it
6 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

ue5-debug-validation is a skill published in the GitHub repository teixasalone/UnrealEngine5-Skills (17 stars, last pushed yesterday), licensed MIT. It adds 54 tokens to every session and 1,032 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to ue5-debug-validation, differing in 0 lines, and is treated as a copy.
Other skills, from other repositories
game-performance
Hit frame budget: draw calls, batching, GC spikes, LOD strategy and in-engine profiling. Use when profiling frame times, draw calls, GPU bottlenecks, or memory.
ue5-debug-validation
UE5.6/UE5.7 debugging and validation workflow for logs, asset checks, and regression triage. Use when requests involve troubleshooting why gameplay does not work, validating expected output, narrowing minimal repro, and producing concrete fix steps.
consistency-check
Scan all GDDs against the entity registry to detect cross-document inconsistencies: same entity with different stats, same item with different values, same formula with different variables. text search-first approach — reads registry then targets only conflicting GDD sections rather than full document reads.
minecraft-debug-mcp
Operate and debug the live Minecraft bot through its built-in MCP REPL server. Use when work requires starting the bot with pnpm dev, connecting to the local MCP endpoint, inspecting cognitive state/logs/history, injecting synthetic chat/events, or running targeted REPL code against the running brain during…
console-get-logs
Retrieve Unity Editor logs from the MCP plugin's LogCollector, optionally filtered by log type or time window. Useful for debugging and monitoring Editor activity.
editor-application-get-state
Return the current state of UnityEditor.EditorApplication — playmode, paused state, compilation state, and related flags.
