ibmi-mcp-server: Instructions file for GitHub Copilot

.github/copilot-instructions.md

ibmi-mcp-server copilot-instructions.md is an instructions file for GitHub Copilot from FanMnz/ibmi-mcp-server. It costs 2,124 tokens per session, scanned C, original, MIT.

A set of instructions for an MCP server that manages source members on IBM i systems, also known as AS/400 systems. Source members are individual editable files stored in IBM i source-physical files.

In plain words
What is it for?
Use it when developing or configuring TypeScript tools that read or write IBM i source members and when checking the server's build or editor setup.
Why use it?
It records the project's setup, dependencies, file layout, and source-marking requirement so agents can work within the intended integration.

Instructions file for GitHub Copilot

Written for GitHub Copilot: a Copilot instructions file.

This is FanMnz/ibmi-mcp-server's own configuration. It tells GitHub Copilot how to work on ibmi-mcp-server 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 ibmi-mcp-server 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.

Security

Grade C, and why

ibmi-mcp-server copilot-instructions.md scanned grade C with 1 finding 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 6d 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.

Hidden instructionshighPrompt injection

Directives inside HTML comments, invisible characters or bidirectional overrides are read by the model and not by the person reviewing the file.

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.
