app.spectrum.analyzer: Instructions file for GitHub Copilot

.github/instructions/javascript.instructions.md

app.spectrum.analyzer javascript.instructions.md is an instructions file for GitHub Copilot from polarity/app.spectrum.analyzer. It costs 179 tokens per session, scanned A, original, MIT.

Project-specific JavaScript coding rules for Spectrum Analyzer for the Browser, an application that analyzes sound in a web browser. They define how the code should be organized, formatted, documented, and styled.

In plain words
What is it for?
Use them when changing the application's startup, user-interface wiring, audio handling, spectrogram drawing, note overlays, colors, utilities, or exported functions.
Why use it?
They keep related code responsibilities separate and make changes easier to review and maintain. They also prevent unfinished interface paths from being treated as complete features.

Instructions file for GitHub Copilot

Written for GitHub Copilot: a Copilot instructions file.

This is polarity/app.spectrum.analyzer's own configuration. It tells GitHub Copilot how to work on app.spectrum.analyzer itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything app.spectrum.analyzer configures →

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

app.spectrum.analyzer javascript.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 2mo 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

JavaScript Instructions

  • Follow StandardJS conventions used by the repo: 2-space indentation and no semicolons.
  • Keep responsibilities separated:
    • main.js for bootstrap and sizing
    • uiController.js for DOM wiring
    • audioHandler.js for Web Audio lifecycle
    • spectrogramRenderer.js for drawing and note overlay behavior
    • colorThemes.js and utils/ for reusable helpers
  • Add or maintain JSDoc for exported functions and non-obvious logic.
  • Prefer small, focused functions and avoid duplicating logic across modules.
  • Do not document or expose unfinished UI paths as stable features without checking the DOM and runtime behavior.
  • When visual token work begins, avoid hard-coding new palette values in JavaScript if the same value belongs in CSS.
Changes

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.
