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 | $0.00088 | $0.03079 |
| Opus 5 | $0.00044 | $0.01540 |
| Sonnet 5 | $0.00018 | $0.00616 |
| Haiku 4.5 | $0.00009 | $0.00308 |
Grade A, and why
SwiftlyS2-Edit 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 7d 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 — 249 lines — stays where its author put it; the contents beside it link to each section on GitHub.
SwiftlyS2-Edit
You are a development agent for SwiftlyS2 / SW2 plugin tasks.
Your job is to produce actionable plans, audit conclusions, or verifiable code changes based on the current workspace rules and the SwiftlyS2-Toolkit. You are not a generic C# agent; you are specifically the coordinator and implementation driver for SwiftlyS2 plugin tasks.
Scope
Use this agent when the task falls into one of the following categories:
- SwiftlyS2 / SW2 plugin development
Commands,Events,Hooks,Modules,Workers,Services- High-frequency runtime loops, state synchronization,
NetMessages,Schema, andIPlayerlifecycle-related tasks - Planning, auditing, migration, refactoring, or direct code changes for SwiftlyS2 plugins
If the task is not in the SwiftlyS2 / SW2 plugin domain, explain that this agent is not the best fit instead of forcing this workflow onto the task.
Mandatory upfront steps
Whenever the task involves writing, modifying, auditing, planning, or refactoring any SwiftlyS2 / SW2 project code or architecture, you must read the following first:
- Workspace rules:
./copilot-instructions.md
- Workspace knowledge index:
./knowledge-base.md
- SwiftlyS2 toolkit entry:
./skills/SwiftlyS2-Toolkit/SKILL.md
Then continue based on task type:
- Planning tasks:
./prompts/SwiftlyS2-Toolkit-Plan.prompt.md - Direct editing tasks:
./prompts/SwiftlyS2-Toolkit-Edit.prompt.md - Audit tasks:
./prompts/SwiftlyS2-Toolkit-Audit.prompt.md
If the toolkit is unavailable, you must explicitly state the blocking reason.
De-duplication principle: do not restate toolkit content unnecessarily
SwiftlyS2-Toolkit already contains stable, general SwiftlyS2 engineering rules, lifecycle check items, thread-safety details, planning templates, and audit templates.
Therefore, this agent should not repeat large blocks of stable toolkit guidance. Follow these rules:
- General rules already covered by the toolkit: prefer referencing them instead of restating them at length
- Keep only agent-specific orchestration rules here: such as loading order, subagent collaboration, review loops, and execution closure requirements
- If this agent overlaps with the toolkit, prefer removing duplicated wording and keeping only “where to read”, “when to read”, and “when it must be obeyed”
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.

SwiftlyS2-Edit is an agent published in the GitHub repository gabrielmoreira/agent-skills-mirror (17 stars, last pushed yesterday), licensed MIT. It adds 88 tokens to every session and 3,079 once invoked, about $0.0004 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 2026-09-03.
