.github/copilot-instructions.md

openmelon copilot-instructions.md is an instructions file for GitHub Copilot from eight-acres-lab/openmelon. It costs 539 tokens per session, scanned A, original, Apache-2.0.

A project-specific set of development rules for the openmelon codebase. It documents the technologies, folder structure, commands, and recent changes, including its Go runtime and language-model provider integration.

In plain words
What is it for?
Guiding development in openmelon, locating source and test files, following project commands, and understanding its language-model provider and command-line options.
Why use it?
It gives an agent the project context needed to make changes that fit the existing code and workflows. It also records constraints such as the use of standard-library Go and local text and JSONL files.

Instructions file for GitHub Copilot

Written for GitHub Copilot: a Copilot instructions file.

This is eight-acres-lab/openmelon's own configuration. It tells GitHub Copilot how to work on openmelon 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 openmelon configures →

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.

Fable 5.1 $0.00539 $0.00539
Opus 5.5 $0.00216 $0.00216

Security

Grade A, and why

openmelon 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.

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.
