codegraph-rules-for-agents: Instructions file for GitHub Copilot

.github/instructions/codegraph.instructions.md

codegraph-rules-for-agents codegraph.instructions.md is an instructions file for GitHub Copilot from codegraph-ai/codegraph-rules-for-agents. It costs 200 tokens per session, scanned A, original, Apache-2.0.

Project instructions for using CodeGraph, a code-intelligence tool, to answer structural questions about a codebase before searching files or reading many of them.

In plain words
What is it for?
It helps find who calls a function, assess what a change may break, gather editing context, search for symbols, and review pull-request impact.
Why use it?
It provides targeted information about symbols, callers, editing context, change impact, and pull requests.

Instructions file for GitHub Copilot

Written for GitHub Copilot: a Copilot instructions file.

This is codegraph-ai/codegraph-rules-for-agents's own configuration. It tells GitHub Copilot how to work on codegraph-rules-for-agents 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 codegraph-rules-for-agents 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

codegraph-rules-for-agents codegraph.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 it actually says

This project uses CodeGraph for code intelligence. Before grep or multi-file reads for structural questions:

  • Who calls X? → codegraph_get_callers (not grep)
  • What breaks if I change X? → codegraph_analyze_impact (not reading imports)
  • Context for editing → codegraph_get_edit_context (not reading 5+ files)
  • Find a symbol → codegraph_symbol_search (not grep -r)
  • PR review → codegraph_pr_context (blast radius + test gaps in one call)

When storing memories, pass agentSource: "copilot".

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.
