Visual Studio Code is a code editor that supports editing, navigating, understanding, debugging, and extending software projects. Developers use it for the edit-build-debug cycle, and the catalogue add-ons provide skills, instructions, and agents for working within the editor.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00219 | $0.00219 |
| Opus 5.5 | $0.00088 | $0.00088 |
| Sonnet 5.5 | $0.00044 | $0.00044 |
| Haiku 4.5 | $0.00022 | $0.00022 |
Grade A, and why
vscode 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.

What it actually says
Core symbols:
-
IDisposabledispose(): void- dispose the object
-
Disposable(implementsIDisposable) - base class for disposable objectsthis._store: DisposableStorethis._register<T extends IDisposable>(t: T): T- Try to immediately register created disposables! E.g.
const someDisposable = this._register(new SomeDisposable())
- Try to immediately register created disposables! E.g.
-
DisposableStore(implementsIDisposable)add<T extends IDisposable>(t: T): Tclear()
-
toDisposable(fn: () => void): IDisposable- helper to create a disposable from a function -
MutableDisposable(implementsIDisposable)value: IDisposable | undefinedclear()- 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).
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.
