Instructions file for GitHub Copilot

Written for GitHub Copilot: a Copilot instructions file.

This is kasuken/vscode-copilot-insights's own configuration. It tells GitHub Copilot how to work on vscode-copilot-insights itself, so it is not a mod to install elsewhere.

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

Project Guidelines 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 6d 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.

GitHub Copilot Insights

  • This repository is a VS Code extension for showing GitHub Copilot plan, quota, reset, history, and AI credit usage insights inside VS Code.
  • Keep extension-host logic in src/, with activation and command/view wiring in src/extension.ts, Copilot data access in src/api/, pure formatting/history/prediction/quota logic in src/core/, and UI-specific code in src/ui/.
  • The extension is bundled to dist/extension.js with esbuild. Extension tests compile TypeScript to the CommonJS out/ tree.

Tech Stack

  • Runtime: VS Code extension API ^1.107.0, UI extension host, Node.js-compatible extension code, and browser-based webviews.
  • Language: TypeScript targeting ES2022 with module: Node16, strict type checking, and DOM library types for webview code.
  • Extension surfaces: package.json contributions for activity bar views, webviews, commands, settings, walkthroughs, localization, and the insights_getCopilotQuota language model tool.
  • UI: VS Code webview HTML/CSS/JavaScript in src/ui/webview/ and media/, VS Code theme variables, Codicons, and offline local assets.
  • Charts: Chart.js 4.x via the bundled UMD asset at media/chart.umd.min.js.
  • Build tooling: npm scripts, esbuild for dist/extension.js, TypeScript compiler for type checks and test emits, and scripts/copy-codicons.mjs for static assets.
  • Quality and tests: ESLint 9 with typescript-eslint, Mocha-style extension tests through @vscode/test-cli and @vscode/test-electron, plus @types/vscode, @types/node, and @types/mocha.

Code Style

  • Make focused TypeScript changes that match nearby style and avoid broad rewrites or formatting churn.
  • Preserve public command IDs, setting keys, view IDs, contribution IDs, exported types, and storage shapes unless the task explicitly requires a migration or breaking change.
  • Prefer pure helpers in src/core/ for behavior that can be unit tested without the VS Code API.
  • Keep user-facing strings localizable through the existing package/l10n patterns when they are surfaced by VS Code or the extension UI.

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.
