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 | $0.01456 | $0.01456 |
| Opus 5.5 | $0.00582 | $0.00582 |
| Sonnet 5.5 | $0.00291 | $0.00291 |
| Haiku 4.5 | $0.00146 | $0.00146 |
Grade A, and why
nyrve tree-widgets.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.
This is a copy
100% identical to vscode tree-widgets.instructions.md — 4 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.

Workbench Tree Widgets Overview
Location: src/vs/platform/list/browser/listService.ts
Type: Platform Services
Layer: Platform
Purpose
The Workbench Tree Widgets provide high-level, workbench-integrated tree components that extend the base tree implementations with VS Code-specific functionality like context menus, keyboard navigation, theming, accessibility, and dependency injection integration. These widgets serve as the primary tree components used throughout the VS Code workbench for file explorers, debug views, search results, and other hierarchical data presentations.
Scope
Included Functionality
- Context Integration: Automatic context key management, focus handling, and VS Code theme integration
- Resource Navigation: Built-in support for opening files and resources with proper editor integration
- Accessibility: Complete accessibility provider integration with screen reader support
- Keyboard Navigation: Smart keyboard navigation with search-as-you-type functionality
- Multi-selection: Configurable multi-selection behavior with platform-appropriate modifier keys
- Dependency Injection: Full integration with VS Code's service container for automatic service injection
- Configuration: Automatic integration with user settings for tree behavior customization
Integration Points
- IInstantiationService: For service injection and component creation
- IContextKeyService: For managing focus, selection, and tree state context keys
- IListService: For registering trees and managing workbench list lifecycle
- IConfigurationService: For reading tree configuration settings
- Resource Navigators: For handling file/resource opening with proper editor integration
Out of Scope
- Low-level tree rendering and virtualization (handled by base tree classes)
- Data management and async loading logic (provided by data sources)
- Custom styling beyond workbench theming integration
Architecture
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.
