What is omnigit-mcp copilot-instructions.md?

Project instructions for a GitHub connector written in Go. The connector lets AI tools work with GitHub repositories, issues, pull requests, and workflows through natural-language requests.

It helps maintain the connector, add or change its GitHub operations, preserve library compatibility, and check changes before committing.

It gives contributors the project context, coding standards, build checks, and validation commands needed before making changes.

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.

Model	Per session	Once invoked
Fable 5.1	$0.03219	$0.03219
Opus 5.5	$0.01288	$0.01288

Security

Grade A, and why

omnigit-mcp 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 2mo 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.

Origin

This is a copy

97% identical to github-mcp-server copilot-instructions.md — 20 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

GitHub MCP Server - Copilot Instructions

Project Overview

This is the GitHub MCP Server, a Model Context Protocol (MCP) server that connects AI tools to GitHub's platform. It enables AI agents to manage repositories, issues, pull requests, workflows, and more through natural language.

Key Details:

Language: Go 1.24+ (~38k lines of code)
Type: MCP server application with CLI interface
Primary Package: omnigit-mcp (stdio MCP server - this is the main focus)
Secondary Package: mcpcurl (testing utility - don't break it, but not the priority)
Framework: Uses modelcontextprotocol/go-sdk for MCP protocol, google/go-github for GitHub API
Size: ~60MB repository, 70 Go files
Library Usage: This repository is also used as a library by the remote server. Functions that could be called by other repositories should be exported (capitalized), even if not required internally. Preserve existing export patterns.

Code Quality Standards:

Popular Open Source Repository - High bar for code quality and clarity
Comprehension First - Code must be clear to a wide audience
Clean Commits - Atomic, focused changes with clear messages
Structure - Always maintain or improve, never degrade
Code over Comments - Prefer self-documenting code; comment only when necessary

Critical Build & Validation Steps

Required Commands (Run Before Committing)

ALWAYS run these commands in this exact order before using report_progress or finishing work:

Format Code: script/lint (runs gofmt -s -w . then golangci-lint)
Run Tests: script/test (runs go test -race ./...)
Update Documentation: script/generate-docs (if you modified MCP tools/toolsets)

These commands are FAST: Lint ~1s, Tests ~1s (cached), Build ~1s

When Modifying MCP Tools/Endpoints

If you change any MCP tool definitions or schemas:

Run tests with UPDATE_TOOLSNAPS=true go test ./... to update toolsnaps
Commit the updated .snap files in pkg/github/__toolsnaps__/
Run script/generate-docs to update README.md
Toolsnaps document API surface and ensure changes are intentional

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.
