Copilot Instructions Lab

v1.1.0

Audit, refactor, and ship pristine .github/copilot-instructions.md, applyTo files, AGENTS.md, and chat-mode prompts — with rules, scores, profiles, suppressions, and PR-ready patches.

A pro-grade audit + builder for GitHub Copilot instructions files — .github/copilot-instructions.md, per-file *.instructions.md with applyTo frontmatter, and AGENTS.md. Paste or drop your files, see a structured issue list with severity, an A–F health score, and one-click fixes; export a unified-diff patch, JSON / Markdown / SARIF audit report, or a paste-ready file. All static analysis — no LLM, no telemetry, no network calls.

How to use
  • →Drop your existing .github/copilot-instructions.md to get an instant audit — the tool flags vague rules, missing frontmatter, length issues, and contradictions.
  • →Use the Profile menu to switch between Default, Strict, and OSS rule sets — or load your own custom profile JSON to enforce house style.
  • →Click Generate patch after applying fixes to get a single .patch file you can ship as a PR — every change is preview-able as a diff first.
