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.

What it costs to keep this loaded
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 | $0.00099 | $0.04296 |
| Opus 5 | $0.00049 | $0.02148 |
| Sonnet 5 | $0.00020 | $0.00859 |
| Haiku 4.5 | $0.00010 | $0.00430 |
Grade A, and why
ue-networking-replication 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 12d 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.
How it starts
The opening of the file, as written. The whole thing — 428 lines — stays where its author put it; the contents beside it link to each section on GitHub.
UE Networking & Replication
You are an expert in Unreal Engine's networking and replication systems.
Context Check
Read .agents/ue-project-context.md for this project's multiplayer configuration.
Look for: server topology (dedicated, listen, P2P), player count, replicated classes,
and any custom net drivers.
If the context file is absent, ask:
- Server topology? (dedicated, listen, P2P)
- Maximum player count per session?
- Which actors or components need to replicate data?
- Are you using Gameplay Ability System (GAS)?
Net Roles and Authority
UE uses a server-authoritative model: the server is the source of truth for game state. Clients predict locally and reconcile with server corrections.
Every actor on every machine has a local role and a remote role (ENetRole).
ROLE_Authority — owns and can modify this actor (server for replicated actors)
ROLE_AutonomousProxy — client copy of the locally controlled pawn
ROLE_SimulatedProxy — client copy of another player's actor; engine interpolates state
ROLE_None — not replicated
From Actor.h:
ENetRole GetLocalRole() const { return Role; } // role on current machine
ENetRole GetRemoteRole() const; // role the other end sees
bool HasAuthority() const { return (GetLocalRole() == ROLE_Authority); }
Net modes: NM_Standalone, NM_DedicatedServer, NM_ListenServer, NM_Client.
Role matrix for a replicated Pawn:
| Machine | GetLocalRole() | GetRemoteRole() |
|---|---|---|
| Server | ROLE_Authority | ROLE_AutonomousProxy or SimulatedProxy |
| Owning Client | ROLE_AutonomousProxy | ROLE_Authority |
| Other Clients | ROLE_SimulatedProxy | ROLE_Authority |
Listen-server caveat: the host is both ROLE_Authority and locally controlled.
Use IsLocallyControlled() to distinguish logic that should skip the host player.
What ships with it
2 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.

ue-networking-replication is a skill published in the GitHub repository quodsoler/unreal-engine-skills (335 stars, last pushed 6mo ago), licensed MIT. It adds 99 tokens to every session and 4,296 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
