SwiftlyS2-Toolkit is a skill for Claude Code from gabrielmoreira/agent-skills-mirror. It costs 75 tokens per session (2,620 once invoked), scanned A, original, MIT.

A toolkit for creating, changing, checking, planning, and reviewing C#/.NET plugins for SwiftlyS2, a game-server plugin framework. It covers plugin commands, events, hooks, services, and player-related code.

In plain words
What is it for?
Use it when building or auditing SwiftlyS2 plugins, especially commands, event hooks, background workers, network messages, and player lifecycle logic.
Why use it?
It gives developers a consistent way to handle common SwiftlyS2 plugin tasks and avoid mistakes in server-runtime code.

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

SwiftlyS2-Toolkit 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 9d 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.

SwiftlyS2-Toolkit

This is a general-purpose toolkit entry for SwiftlyS2 C# / .NET plugin development.

Its goal is not to bind itself to any specific workspace, but to provide a publicly reusable workflow, rule set, template collection, and reference navigation system.

Public reference allowlist

The public docs, prompts, agents, and templates in this toolkit should, by default, reference only the following public sources:

  1. SwiftlyS2 official documentation: https://swiftlys2.net/docs/
  2. sw2-mdwiki: https://github.com/himenekocn/sw2-mdwiki
  3. SwiftlyS2 official repository: https://github.com/swiftly-solution/swiftlys2

If the current workspace has workspace-specific mappings, local reference repositories, historical reference projects, or special rules, that information may only be recorded in:

  • ./copilot-instructions.md

  • ./knowledge-base.md

  • If the workspace includes a local sw2-mdwiki checkout, it is strongly recommended to use it as a local reference repository to improve agent retrieval efficiency and accuracy.

What this skill should produce

When using this skill, the preferred output should be one of the following:

  • An implementation plan for a new plugin or new module
  • A direct modification plan for an existing plugin
  • A gap analysis for historical behavior alignment
  • An audit of lifecycle, thread safety, high-frequency hooks, Schema, or Protobuf usage
  • A method-level implementation plan

When to use it

Use this skill when the task involves:

  • SwiftlyS2 plugin development
  • Commands, Events, Hooks, Modules, Workers, Services
  • High-frequency runtime loops and state synchronization
  • Schema, NetMessages, Protobuf, or IPlayer lifecycle handling
  • High-frequency hooks, async workers, main-thread-sensitive APIs, or entity lifecycle handling
  • Plugin migration, behavior alignment, structural audits, or method-level planning

When not to use it

  • Regular C# work unrelated to SwiftlyS2
  • Pure frontend UI work
  • A one-off tiny change that does not require architecture, lifecycle, or thread-boundary judgment

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.
