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.
npx agentmods add instructions/feiskyer/claude-code-settings/copilot-instructionsgit clone --depth 1 https://github.com/feiskyer/claude-code-settingsWhat 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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00649 | $0.00649 |
| Opus 5 | $0.00324 | $0.00324 |
| Sonnet 5 | $0.00130 | $0.00130 |
| Haiku 4.5 | $0.00065 | $0.00065 |
Grade A, and why
claude-code-settings 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 2d 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 — 81 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CLAUDE.md
This file provides guidance to Claude Code and GitHub Copilot when working with code in this repository.
Environment Setup
This repository contains Claude Code settings, configurations and guidance. The default setup uses GitHub Copilot as the model provider through a proxy API.
Required Dependencies
copilot-gateway: Run withnpx copilot-gateway@latest start --proxy-envto start the proxy and authorize GitHub Copilot account- Use tmux for session management:
tmux new-session -d -s copilot 'npx copilot-gateway@latest start --proxy-env'
Configuration
settings.json: Contains environment variables for API configuration- Uses
localhost:4141as the API base URL - Telemetry and non-essential traffic are disabled
Skills
Skills are reusable capabilities defined in the skills/ directory. Each skill has a SKILL.md file with YAML frontmatter containing name and description fields. The description serves as both documentation and trigger condition.
Skill File Structure
All skill files must include YAML frontmatter:
---
name: skill-name
description: 'Comprehensive description that also serves as the trigger condition. Include keywords and phrases that should activate this skill.'
---

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.

claude-code-settings copilot-instructions.md is an instructions file published in the GitHub repository feiskyer/claude-code-settings (1,644 stars, last pushed 19d ago), licensed MIT. It adds 649 tokens to every session, about $0.0032 per session on Opus 5. A static security scan graded it A with 0 findings.
