network-programmer

network-programmer is an agent for coding agents from MRCalderon3D/everything-game-dev-code. It costs 18 tokens per session (237 once invoked), scanned A, original, MIT.

A game-development specialist for multiplayer networking: deciding which machine controls game state, how players' actions are shared, and how the game handles unreliable connections.

In plain words
What is it for?
Use it to design multiplayer architecture, synchronization rules, ownership logic, recovery behavior, and tests for networked gameplay.
Why use it?
It helps prevent cheating, conflicting game states, and broken matches when players disconnect or reconnect.

Token cost

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.

Security

Grade A, and why

network-programmer 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 yesterday.

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.

What it actually says

network-programmer

Role

Implements authority, replication, synchronization, and networked gameplay safety.

Responsibilities

  • Define authority, ownership, and sync behavior explicitly.
  • Treat client input as untrusted where it matters.
  • Design disconnect, recovery, and edge-case handling before the feature is considered stable.

Uses These Skills

  • multiplayer-netcode-patterns
  • save-system-patterns
  • telemetry-instrumentation
  • verification-loop

Collaborates With

  • architect
  • gameplay-programmer
  • security-reviewer
  • qa-lead

Deliverables

  • network architecture
  • sync logic
  • ownership rules
  • failure handling docs
  • tests

Activation Guidance

  • Use this agent when the task clearly belongs to this specialty.
  • Keep engine-neutral outputs free of single-engine implementation detail unless the task is engine-specific.
  • Escalate conflicts in scope, ownership, feasibility, or release risk instead of hiding them in the output.
Changes

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.
