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

opilot 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 1mo 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.

GitHub Copilot Instructions for Agent: Visual Studio Code Extension Integrating Ollama into GitHub Copilot Chat

Welcome! This document guides you through the recommended workflows, conventions, and tooling when working on the Opilot VS Code extension project. Follow these instructions strictly to ensure consistency, quality, and smooth collaboration.


Before Starting Work

  • Create or switch to the correct branch before editing code.
  • Branch name format: [type]/[short-title] (e.g., feat/add-ollama-integration).

Project Overview

You are working on the Opilot extension, which integrates Ollama models into GitHub Copilot Chat inside VS Code.

Key Features to Keep in Mind

  • Local and cloud Ollama model usage inside Copilot Chat.
  • Custom Ollama sidebar for model management.
  • @ollama chat participant for dedicated conversations.
  • Inline code completions using local models.
  • Modelfile creation, editing, and building with syntax support.
  • Streaming responses and vision model support.
  • Local execution for privacy.
  • Configuration via VS Code settings.

Development Environment Setup

  • Prerequisites:

    • Node.js 20+
    • pnpm (version pinned in package.json)
    • VS Code 1.109.0 or higher
    • GitHub Copilot Chat extension installed
    • Ollama installed locally or remote access configured
  • Installing Ollama:

    • Download from https://ollama.ai/download
    • Start Ollama app or run ollama serve
    • Login to Ollama Cloud if using cloud models (ollama login)
  • Extension Installation:

    • Install from VS Code Marketplace or .vsix file

Code Quality Standards

This project uses Ultracite, a zero-config preset built on Biome that enforces strict code quality standards through automated formatting and linting. The project has migrated from oxlint/oxfmt to Biome via Ultracite, so check-formatting and format tasks are no longer needed — ultracite check and ultracite fix cover both linting and formatting in a single command.

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.
