Refactoring

Refactoring is a command for GitHub Copilot from jnPiyush/AgentX. It costs 11 tokens per session (350 once invoked), scanned A, original, Apache-2.0.

A code-refactoring prompt for finding design and maintenance problems in existing code and proposing concrete improvements. Refactoring changes code structure without changing its intended behaviour.

In plain words
What is it for?
Use it to review code for readability, complexity, maintainability, performance, and testability, then produce before-and-after suggestions.
Why use it?
It gives common problems such as long methods, deep nesting, duplication, and hard-to-test code a consistent review format.

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

Refactoring 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 today.

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.

Refactoring Prompt

Context

You are refactoring code for Issue #{{issue_number}}.

Analyze the provided code and suggest refactoring improvements.

Before refactoring, read this file first:

  • .github/skills/architecture/core-principles/SKILL.md

Refactoring Goals

  1. Improve Readability - Make code self-documenting
  2. Reduce Complexity - Simplify logic and control flow
  3. Enhance Maintainability - Follow SOLID principles
  4. Optimize Performance - Identify bottlenecks
  5. Increase Testability - Enable easier unit testing

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.
