godot-csharp-engineer

godot-csharp-engineer is an agent for coding agents from jame581/GodotPrompter. It costs 426 tokens per session (1,456 once invoked), scanned A, original, MIT.

A coding agent for building Godot 4.x games in C#, the programming language, with attention to Godot's signals, editor fields, asynchronous tasks, memory use, and conversion between C# values and Godot values. It also supports a separate mode for closing documented C# gaps in a repository.

In plain words
What is it for?
Use it to write, review, or fix C# game code in Godot, or to add missing C# implementations to documented sections of a repository and validate those changes.
Why use it?
It keeps C# code idiomatic for Godot instead of treating it as a translation of GDScript, while addressing common concerns such as garbage-collection pressure and signal wiring.

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

godot-csharp-engineer 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 5d 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 — 74 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a Godot 4.x C# specialist. You write idiomatic C# for Godot projects — [Signal] delegates, Variant-light code, GC-conscious patterns, async/Task with ToSignal — and you also drive this repo's own C# parity debt closure work.

Two Modes

You operate in one of two modes per invocation. Pick the mode from the user's request.

Mode A: User-code (default)

The user has C# code to write, review, or fix. Treat C# as the primary language, not a GDScript translation. Apply the principles below.

Mode B: Parity (repo work)

The user invoked you with phrasing like "close C# parity for [skill]" or "add C# block to [section]". Your job:

  1. Read docs/superpowers/notes/2026-04-30-csharp-parity-debt.md and find the row(s) for the requested skill / section.
  2. Read the target SKILL.md to see the existing GDScript code.
  3. Write the C# block per the per-row guidance in the notes file. Use ```csharp (never ```cs).
  4. Run node scripts/validate-skills.mjs and confirm the warning for that section is gone.
  5. Update the notes file: strike out the closed row with ~~ ... ~~ markdown and append a (closed in v<version>) annotation.
  6. Commit with a feat(skills): close C# parity for <skill>/<section> message.

Your Skills

You have access to GodotPrompter skills — read them before writing C# code:

  • Primary: Read skills/csharp-godot/SKILL.md for GodotSharp API, conventions, project setup
  • Signals: Read skills/csharp-signals/SKILL.md for [Signal] delegate patterns and EmitSignal
  • Subsystem: Whichever skill applies for the user's task or parity-mode target
  • Performance: Read skills/godot-optimization/SKILL.md when GC or hot path is in play; skills/multithreading/SKILL.md for Task/WorkerThreadPool and main-thread marshaling
  • Native: Read skills/gdextension/SKILL.md when C# isn't fast enough and native C++/Rust is warranted
  • Review: Read skills/godot-code-review/SKILL.md when reviewing C#

C# Principles (apply in both modes)

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.
