Agent Experience Graph for VS Code

An early IDE integration for discovering, recommending, rating, and measuring agent skills directly inside a developer workspace.

Install

Install Agent Experience Graph from the Visual Studio Code Marketplace, then open a workspace containing SKILL.md or capability.json files.

For a local VSIX build:

npm install
npm run package
code --install-extension agent-experience-graph-0.1.0.vsix

MVP Features

• Discovers local SKILL.md and capability.json files.
• Recommends skills for selected code/text or a task description.
• Opens the selected skill or copies its path for use by an agent.
• Records local skill-use counts and estimated selection-context tokens.
• Lets developers rate skills from 1 to 5.
• Displays usage, estimated tokens, and average ratings.

Metrics remain local in .aeg/skill-metrics.json by default. This MVP does not send telemetry to a hosted service.

Run Locally

cd integrations/vscode
npm install
npm run compile

Open this directory in VS Code and press F5 to launch an Extension Development Host.

Commands

Open the Command Palette and run:

• AEG: Discover Workspace Skills
• AEG: Recommend Skill for Current Task
• AEG: Rate a Skill
• AEG: Show Skill Metrics

You can also select text in an editor, right-click, and choose AEG: Recommend Skill for Current Task.

Skill Discovery

The extension scans these workspace patterns by default:

[
  "**/SKILL.md",
  "**/capability.json"
]

They can be changed with aeg.skillGlobs.

Local Metrics Format

{
  "skills/example/SKILL.md": {
    "uses": 4,
    "totalEstimatedTokens": 820,
    "ratings": [5, 4],
    "lastUsed": "2026-07-15T12:00:00.000Z"
  }
}

The current token number is an estimate based on text length. A production version should collect actual model usage from supported agent runtimes.

Next Steps

• Semantic embeddings and hybrid ranking instead of keyword overlap.
• Parse richer skill manifests: inputs, outputs, tools, constraints, and compatibility.
• Connect to Codex, OpenAI Agents SDK, Claude Code, MCP, and other runtimes.
• Record actual tokens, cost, latency, retries, validation results, and success rate.
• Add trusted automatic skill loading/install with permission boundaries.
• Publish team and community skill leaderboards.
• Package and publish to the VS Code Marketplace and Open VSX.
