nyrve: Instructions file for GitHub Copilot

.github/instructions/disposable.instructions.md

nyrve disposable.instructions.md is an instructions file for GitHub Copilot from malwarebo/nyrve. It costs 219 tokens per session, scanned A, a copy of vscode disposable.instructions.md, MIT.

Guidelines for managing objects that must release resources when they are no longer needed. They describe disposable objects, groups of disposables, and replaceable disposable values.

In plain words
What is it for?
Use them when writing code with IDisposable, such as objects that hold subscriptions, event handlers, timers, or other resources requiring cleanup.
Why use it?
They help prevent resource leaks and make cleanup happen consistently when objects are cleared, replaced, or closed.

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

nyrve disposable.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.

Origin

This is a copy

100% identical to vscode disposable.instructions.md — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

Core symbols:

  • IDisposable

    • dispose(): void - dispose the object

  • Disposable (implements IDisposable) - base class for disposable objects

    • this._store: DisposableStore
    • this._register<T extends IDisposable>(t: T): T
      • Try to immediately register created disposables! E.g. const someDisposable = this._register(new SomeDisposable())

  • DisposableStore (implements IDisposable)

    • add<T extends IDisposable>(t: T): T
    • clear()

  • toDisposable(fn: () => void): IDisposable - helper to create a disposable from a function

  • MutableDisposable (implements IDisposable)

    • value: IDisposable | undefined
    • clear()
    • A value that enters a mutable disposable (at least once) will be disposed the latest when the mutable disposable is disposed (or when the value is replaced or cleared).
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.
