What it does

Memory Leak Audit is an agent skill from diodeme/Gold-Band. Audit code for memory leaks and disposable issues. Use when reviewing event listeners, DOM handlers, lifecycle callbacks, or fixing leak reports. Covers addDisposableListener, Event.once, MutableDisposable, DisposableStore, and onWillDispose patterns.

Its SKILL.md is about 1.3k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Development, covering Performance optimization. The repository describes itself as: Desktop app for harness engineering, loop engineering, graph engineering—and whatever comes next in local AI-agent workflows. The licence is AGPL-3.0.

When your agent uses it

Reviewing event listeners
Lifecycle callbacks
Fixing leak reports

Example prompts

“/memory-leak-audit”

Workflow steps

6 steps, taken from the step headings in SKILL.md.

DOM Event Listeners
One-Time Events
Repeated Method Calls
Model-Tied DisposableStores
Resource Pool Patterns
Test Validation

What it can do on your machine

Read from SKILL.md and the folder at commit 75622ac. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are typescript).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Memory Leak Audit loads about 1.3k tokens when it runs. Until then it costs about 67 tokens; SKILL.md has 365 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~67
When it runs · the whole SKILL.md, loaded when a task matches: ~1.3k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

name: memory-leak-audit
description: Audit code for memory leaks and disposable issues. Use when reviewing event listeners, DOM handlers, lifecycle callbacks, or fixing leak reports. Covers addDisposableListener, Event.once, MutableDisposable, DisposableStore, and onWillDispose patterns.

Memory Leak Audit

The #1 bug category in VS Code. This skill encodes the patterns that prevent and fix leaks.

When to Use

Reviewing code that registers event listeners or DOM handlers
Fixing reported memory leaks (listener counts growing over time)
Creating objects in methods that are called repeatedly
Working with model lifecycle events (onWillDispose, onDidClose)
Adding event subscriptions in constructors or setup methods

Audit Checklist

Work through each check in order. A single missed pattern can cause thousands of leaked objects.

Step 1: DOM Event Listeners

Rule: Never use raw .onload, .onclick, or addEventListener() directly. Always use addDisposableListener().

typescript

// BAD — leaks a listener every call
this.iconElement.onload = () => { ... };

// GOOD — tracked and disposable
this._register(addDisposableListener(this.iconElement, 'load', () => { ... }));

Validated by: PR #280566 — Extension icon widget leaked 185 listeners after 37 toggles.

Step 2: One-Time Events

Rule: Use Event.once() for events that should only fire once (lifecycle events, close events, first-change events).

typescript

// BAD — listener stays registered forever after first fire
model.onDidDispose(() => store.dispose());

// GOOD — auto-removes after first invocation
Event.once(model.onDidDispose)(() => store.dispose());

Validated by: PRs #285657, #285661 — Terminal lifecycle hacks replaced with Event.once().

Step 3: Repeated Method Calls

Rule: Objects created in methods called multiple times must NOT be registered to the class this._register(). Use MutableDisposable or return IDisposable to the caller.

typescript

// BAD — every call adds another listener to the class store
startSearch() {
    this._register(this.model.onResults(() => { ... }));
}

// GOOD — MutableDisposable ensures max 1 listener
private readonly _searchListener = this._register(new MutableDisposable());

startSearch() {
    this._searchListener.value = this.model.onResults(() => { ... });
}

When the event should only fire once per method call, combine Event.once() with MutableDisposable — this auto-removes the listener after the first invocation while still guarding against repeated calls:

typescript

private readonly _searchListener = this._register(new MutableDisposable());

startSearch() {
    this._searchListener.value = Event.once(this.model.onResults)(() => { ... });
}

Validated by: PR #283466 — Terminal find widget leaked 1 listener per search.

Step 4: Model-Tied DisposableStores

Rule: When creating a DisposableStore tied to a model's lifetime, register model.onWillDispose(() => store.dispose()) to the store itself.

typescript

const store = new DisposableStore();
store.add(model.onWillDispose(() => store.dispose()));
store.add(model.onDidChange(() => { ... }));

Validated by: Pattern used in chatEditingSession.ts, fileBasedRecommendations.ts, testingContentProvider.ts.

Step 5: Resource Pool Patterns

Rule: When using factory methods that create pooled objects (lists, trees), disposables must be registered to the individual item, not the pool class.

typescript

// BAD — registers to pool, never cleaned per item
createItem() {
    const item = new Item();
    this._register(item.onEvent(() => { ... }));
    return item;
}

// GOOD — wrap with item-scoped disposal
createItem(): IDisposable & Item {
    const store = new DisposableStore();
    const item = new Item();
    store.add(item.onEvent(() => { ... }));
    return { ...item, dispose: () => store.dispose() };
}

Validated by: PR #290505 — Chat content parts CollapsibleListPool and TreePool leaked disposables.

Step 6: Test Validation

Rule: Every test suite that creates disposable objects must call ensureNoDisposablesAreLeakedInTestSuite().

typescript

import { ensureNoDisposablesAreLeakedInTestSuite } from '../../../../base/test/common/utils.js';

suite('MyFeature', () => {
    ensureNoDisposablesAreLeakedInTestSuite();

    test('does something', () => {
        // test disposables are tracked automatically
    });
});

Quick Reference

Scenario	Pattern	Anti-Pattern
DOM events	`addDisposableListener()`	`.onclick =`, `addEventListener()`
One-time events	`Event.once(event)(handler)`	`event(handler)` for lifecycle
Repeated methods	`MutableDisposable` or return `IDisposable`	`this._register()` in non-constructor
Model lifecycle	`store.add(model.onWillDispose(...))`	Forgetting cleanup
Pooled objects	Item-scoped `DisposableStore`	Pool-scoped `this._register()`
Tests	`ensureNoDisposablesAreLeakedInTestSuite()`	No leak checking

Verification

After fixing leaks, verify by:

Checking listener counts before/after repeated operations
Running ensureNoDisposablesAreLeakedInTestSuite() in tests
Confirming object counts stabilize (don't grow linearly with usage)
