okf-rs: Instructions file for GitHub Copilot

.github/copilot-instructions.md

okf-rs copilot-instructions.md is an instructions file for GitHub Copilot from jyjeanne/okf-rs. It costs 207 tokens per session, scanned A, original, Apache-2.0.

Project-specific instructions and a searchable knowledge base describing the code's modules, types, functions, and call relationships.

In plain words
What is it for?
Use it to look up code concepts, inspect the public API, trace callers and callees, find call cycles, and regenerate the knowledge base after code changes.
Why use it?
They reduce the need to reconstruct the project's structure by reading many files. They also provide ways to find symbols and trace which functions call or are called by others.

Instructions file for GitHub Copilot

Written for GitHub Copilot: a Copilot instructions file.

This is jyjeanne/okf-rs's own configuration. It tells GitHub Copilot how to work on okf-rs 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 okf-rs 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

okf-rs 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 it actually says

Knowledge base

This project's structural knowledge — modules, types, functions, and their call graph — is available as an OKF bundle in knowledge/. It's plain markdown with YAML frontmatter; browse knowledge/index.md for an overview, or query it with the CLI:

  • okf-rs search <query> — find a symbol, type, or module by name or tag
  • okf-rs graph callers <id> / okf-rs graph callees <id> — trace the call graph from a concept id (ids are shown by search)
  • okf-rs graph api — list the public API surface
  • okf-rs graph cycles — list call-graph cycles

Regenerate the bundle after code changes with okf-rs generate.

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.
