vscode: Skill for Claude Code

.github/skills/accessibility/SKILL.md

accessibility is a skill for Claude Code, Codex from microsoft/vscode. It costs 54 tokens per session (3,694 once invoked), scanned A, original, MIT.

Accessibility guidance for building or changing interactive VS Code features, such as panels, views, dialogs, and editor controls. Accessibility means making software usable with keyboards, screen readers, and other assistive tools.

In plain words
What is it for?
Adding accessibility help, plain-text accessible views, keyboard navigation, screen-reader announcements, ARIA labels and roles, and related settings.
Why use it?
It helps prevent new interface work from excluding people who cannot use a mouse or see the screen, and ensures important information is announced and navigable.

Written for no agent in particular: nothing here depends on one.

This is microsoft/vscode's own configuration. It tells Claude Code and Codex how to work on vscode 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 vscode configures →

Needs its repository: it reads a path above its own folder, which exists only inside the repository. The line is import { AccessibleViewType, AccessibleContentProvider, AccessibleViewProviderId } from '../../../../platform/accessibility/browser/accessibleView.js';.

About the project

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.

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

accessibility 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 yesterday.

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.

When to Use This Skill

Use this skill for any VS Code feature work that introduces or changes interactive UI. Use this skill by default for new features and contributions, including when the request does not explicitly mention accessibility.

Trigger examples:

  • "add a new feature"
  • "implement a new panel/view/widget"
  • "add a new command or workflow"
  • "new contribution in workbench/editor/extensions"
  • "update existing UI interactions"

Do not skip this skill just because accessibility is not named in the prompt.

When adding a new interactive UI surface to VS Code — a panel, view, widget, editor overlay, dialog, or any rich focusable component the user interacts with — you must provide three accessibility components (if they do not already exist for the feature):

  1. An Accessibility Help Dialog — opened via the accessibility help keybinding when the feature has focus.
  2. An Accessible View — a plain-text read-only editor that presents the feature's content to screen reader users (when the feature displays non-trivial visual content).
  3. An Accessibility Verbosity Setting — a boolean setting that controls whether the "open accessibility help" hint is announced.

Examples of existing features that have all three: the terminal, chat panel, notebook, diff editor, inline completions, comments, debug REPL, hover, and notifications. Features with only a help dialog (no accessible view) include find widgets, source control input, keybindings editor, problems panel, and walkthroughs.

Sections 4–7 below (signals, ARIA announcements, keyboard navigation, ARIA labels) apply more broadly to any UI change, including modifications to existing features.

When updating an existing feature — for example, adding new commands, keyboard shortcuts, or interactive capabilities — you must also update the feature's existing accessibility help dialog (provideContent()) to document the new functionality. Screen reader users rely on the help dialog as the primary way to discover available actions.
