ai-coding-rules copilot-instructions.md is an instructions file for GitHub Copilot from zoxknez/ai-coding-rules. It costs 206 tokens per session, scanned A, original, MIT.

Canonical coding rules for AI agents, including a test-first workflow, response format, and conditions for stopping.

In plain words
What is it for?
Use them to structure coding responses, keep changes minimal, avoid secrets and personal data, and pause before security risks, data loss, breaking changes, or large unapproved edits.
Why use it?
They set shared expectations for safe, focused changes and make plans, patches, verification, and risks explicit.

Instructions file for GitHub Copilot

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

ai-coding-rules 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 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.
