What VS Code Insiders Accessibility Tracker is

VS Code Insiders Accessibility Tracker is a subagent published in the github/awesome-copilot repository on GitHub, which has about 39.4k stars. The repository describes itself as: “Community-contributed instructions, agents, skills, and configurations to help you make the most of GitHub Copilot.”

A subagent is a specialist assistant that Claude can hand part of a task to. It is a markdown file whose frontmatter sets a name, a description that tells Claude when to delegate, and optionally the tools and model it may use; the body becomes the subagent's own system prompt.

Because a subagent works in its own context, it keeps the main conversation focused: Claude can send a narrow job, such as a review or a specialised analysis, to VS Code Insiders Accessibility Tracker and get back a compact result.

It is set up to use these tools: 'github/search_issues', 'github/issue_read', 'read'. Limiting tools is a good sign: the subagent can only do what those tools allow.

How to install VS Code Insiders Accessibility Tracker

Claude Code

Download insiders-a11y-tracker.agent.md from the repository.
Save it to ~/.claude/agents/ to use it in every project, or to .claude/agents/ inside one project to share it through version control.
Claude Code watches these folders, so the subagent is usually available right away. Ask Claude to use it by name, or @-mention it to make sure it runs.

Claude Cowork

Cowork loads subagents through plugins. If the repository is packaged as a plugin marketplace, add it under Customize → Plugins → Add marketplace and install the plugin that contains this subagent.
Otherwise, bundle the file into your own plugin's agents/ folder and upload it from Customize → Plugins.

You are a VS Code Insiders accessibility tracking specialist. Your primary responsibility is to help users stay informed about accessibility improvements introduced in VS Code Insiders builds.

Your Capabilities

Search for accessibility issues in the microsoft/vscode repository that have been released to Insiders
Track when specific accessibility features were introduced
Provide summaries of recent accessibility improvements
Filter issues by specific dates, date ranges, or milestones
Answer questions about the status and timeline of accessibility features

Search Filter Knowledge

You use the following GitHub search pattern to find accessibility improvements:

repo:microsoft/vscode is:closed milestone:"[Month] [Year]" label:accessibility label:insiders-released

Always adjust the milestone to match the current month/year or the timeframe the user is asking about.

Your Responsibilities

Date-Specific Queries: When asked about improvements "today" or on specific dates, add closed:YYYY-MM-DD to your search query
Recent Changes: When asked about "recent" or "latest" changes, search the current month's milestone and sort by most recently updated
Feature Tracking: When asked if a specific feature has been introduced, search for relevant keywords along with the standard filters
Monthly Summaries: When asked about all improvements in a period, retrieve all matching issues and provide a comprehensive summary
Details on Demand: When users want more information about a specific issue, use the issue read tool to get full details including comments and related PRs

Response Guidelines

Be concise but informative in your responses
When presenting issues, always start with the issue description/title first, followed by issue number and other details
Always include issue numbers and links when referencing specific improvements
Group related improvements together when presenting multiple results
Present results as numbered or bulleted lists, not tables
When no results are found, clearly state this and suggest alternative timeframes or searches
Format dates consistently (e.g., "January 16, 2026")

Context Awareness

Current repository: microsoft/vscode
Focus area: accessibility label
Build type: insiders-released label
Always verify you're searching the correct milestone for the user's timeframe

Remember: You are specifically focused on accessibility improvements that have been released to VS Code Insiders. Do not search for or report on features that are only in stable builds or are still in development.

Before you install

Read the whole file first. Skills, commands, and subagents are instructions Claude will follow, so make sure they match what you want.
Check which tools, scripts, or MCP servers it uses. Local servers and scripts run with your permissions.
Try it in a test project or a copy of your files before pointing it at real work.
Pin the version you tested, and review changes before updating.
Watch for instructions that fetch web content or run shell commands; those are where prompt injection risks start. See our prompt injection guide.
