grafel: Instructions file for GitHub Copilot

.github/copilot-instructions.md

grafel copilot-instructions.md is an instructions file for GitHub Copilot from cajasmota/grafel. It costs 358 tokens per session, scanned A, original, MIT.

Instructions for using Grafel, an architecture knowledge graph available through MCP, to understand how code entities relate across a repository.

In plain words
What is it for?
Use it to inspect code structure, trace calls, follow frontend-to-backend links, and decide when Grafel or ordinary text search is the better tool.
Why use it?
It helps an agent find definitions, callers, imports, source code, and end-to-end paths without manually searching and reading unrelated files.

Instructions file for GitHub Copilot

Written for GitHub Copilot: a Copilot instructions file.

This is cajasmota/grafel's own configuration. It tells GitHub Copilot how to work on grafel 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 grafel 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 A, and why

grafel 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.

What it actually says

grafel MCP

This repo is part of grafel group grafel. grafel is an architecture knowledge graph available via MCP. When you (an AI coding agent) need to understand how this codebase fits together, prefer the grafel MCP tools over grep + reading files.

When to use grafel instead of grep

Question shape Prefer
"Where is X defined?" grafel_find
"What does X look like + its neighbors?" grafel_inspect
"Who calls X?" grafel_expand / grafel_find_callers
"End-to-end flow when user does X?" grafel_traces
"How does the frontend talk to the backend?" grafel_cross_links
"Show me the source of X" grafel_get_source

When grep IS still better

  • Substring search across all files for non-entity strings (comments, TODOs).
  • Anything where you need raw file contents in bulk.

Anti-patterns

  • Don't read an entire file to find one function — grafel_inspect returns it directly.
  • Don't glob for a class name across the repo — grafel_find indexes it.
  • Don't traverse imports manually — grafel_expand does it via the IMPORTS edge.

The full agent guide is delivered automatically in the MCP instructions handshake when you connect.

Do not edit between the markers — this block is auto-updated by grafel install.

Changes

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.
