Instructions file for GitHub Copilot

Written for GitHub Copilot: a Copilot instructions file.

This is gpsnmeajp/ai-character-checker's own configuration. It tells GitHub Copilot how to work on ai-character-checker itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything ai-character-checker configures →

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is python scripts/merge_all_in_one.py # 実行.

Reuse

Nothing to install: this file belongs to gpsnmeajp/ai-character-checker. Take a copy, put it at the same path in your own repository, and replace the rules that are about this project with yours.

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

ai-character-checker copilot-instructions.md 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.

AI Character Checker — ワークスペースガイド

このリポジトリは、AIキャラクターの多角的な分析・診断・修復・変換・新規作成を行う 20個のスキルファイル群 である。
対象は creative-writing キャラクターおよび LLM 向けシステムプロンプトの両方。
日本語・日本サブカル文化前提。動作確認モデルは Claude Opus 4.6。ライセンスは CC0。

作成するスキルは、skill-creatorの基準で適切かどうかを確認すること。 ただし、descriptionが短いのは意図的(システムプロンプト汚染防止)である。

注意!行数のカウントには、カウント用のpythonスクリプトを作成し、それでカウントしてください。 Powershellによるカウントでは空行がカウントされず、オーバーフローしているのを確認しています。

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.
