.github/instructions/clean-code.instructions.md

clean-code-skills clean-code.instructions.md is an instructions file for GitHub Copilot from Amartuvshins0404/clean-code-skills. It costs 237 tokens per session, scanned A, original, MIT.

A set of instructions for making code easier to understand, change, and verify. It covers preparation, implementation, testing, and reviewing the final change.

In plain words
What is it for?
Use it before and during coding, refactoring, testing, or configuration work to clarify assumptions, keep changes focused, and run relevant verification.
Why use it?
It reduces unrelated edits, unclear boundaries, speculative features, and changes that are hard for the next maintainer to check.

Instructions file for GitHub Copilot

Written for GitHub Copilot: a Copilot instructions file.

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

clean-code-skills clean-code.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

Clean-Code Instructions

Apply these rules to every file type unless a more specific instruction file overrides them.

Before Editing

  • Identify what behavior the request changes.
  • Read the closest existing implementation and tests.
  • State assumptions when ambiguity affects the design.
  • Define a verification step for non-trivial changes.

While Editing

  • Keep each change directly traceable to the request.
  • Use project vocabulary in names.
  • Keep functions, modules, components, queries, scripts, and configuration focused.
  • Prefer explicit data flow and explicit boundaries.
  • Do not introduce framework swaps, new layers, caches, queues, retries, or configuration unless the task requires them.
  • Distinguish essential complexity (the problem) from accidental complexity (how it was built); only the second is yours to fix in passing.
  • Treat every observable behavior of a multi-user interface as part of the contract; change with care or version it.

Before Completion

  • Run the relevant verification command when available.
  • Review the diff for unrelated edits and speculative complexity.
  • Remove only dead code created by the current change.
  • Report any verification you could not run.

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.
