Fo shure, Vlad! Let me put on a show with the tools. I'll do a bunch of things in parallel to demonstrate the range.
Let me start by exploring what we have and kicking off some research simultaneously.
List files in demo directory
Glob**/*
Agent
Empty directory — perfect canvas. I've got a research agent running in the background looking into 2026 programming trends. Meanwhile, let me create a small demo project and showcase some file operations.
Writeapp.py
Writeconfig.json
Created two files. Now let me run the app, do some edits, and use search tools — all in parallel.
Run the demo app
Readconfig.json
Grepdef \w+
App runs, 7 methods found via Grep, config looks good. Now let me edit both files to showcase the Edit tool, and fire off a web search.
Editapp.py
Editconfig.json
ToolSearch
Now let me run the updated app and do a live web search simultaneously.
Run updated demo app with percentage
Readapp.py
Search
Claude Code CLI new features 2026
The percentage edit works — 1/3 tasks completed (33%). And the web search pulled back some fresh Claude Code news. Let me also check what the background research agent found, and do one more thing — let me fetch a webpage and show the updated config.
Readconfig.json
Check background agent output
The background agent didn't have web search access (subagents don't inherit all MCP tools) — no worries, I already got the info from my own web search. Let me do one final showcase round: a Glob search, a Grep across files, and a quick Bash pipeline.

Count lines and show Python version
Here's the recap of everything I just showcased, Vlad:
Tools Used
| Tool | What I Did |
|---|---|
| Bash | Ran ls, executed app.py (twice), counted lines, checked Python version |
| Write | Created app.py and config.json from scratch |
| Read | Read back both files to verify content |
| Edit | Modified app.py (added percentage to summary) and config.json (bumped max_tasks, added features array) |
| Glob | Pattern-searched for **/*.{py,json} |
| Grep | Regex searched for Vlad |
| WebSearch | Searched for Claude Code 2026 features (live web results) |
| Agent | Launched a background research subagent (it lacked web tools, but demonstrated async dispatch) |
| ToolSearch | Loaded the deferred WebSearch tool on-demand |
Parallel Execution Highlights
3-way parallel:

Bash(run app)+Grep(methods)+Read(config)3-way parallel:
Glob+Grep+Bash(wc + python)
Fo shure, that's a solid tour of the toolbox. Two files created, two files edited, web research done, background agent dispatched, and search tools exercised — all with parallel execution wherever possible.

I don't have a web search tool available in my current environment, Vlad. I can't browse the internet or perform web searches — my tools are limited to local file operations, shell commands, and code search.
Here's what I can suggest:
You could run a quick search yourself using your browser or a CLI tool like
curlagainst a search API.If you have a web search MCP tool installed, let me know and I can use it.
Based on my training data (up to May 2025), I can share what the trajectory looked like heading into 2026, but I'd be honest that it wouldn't reflect actual 2026 data.
Want me to give you a best-guess summary based on what I know up to mid-2025, with the caveat that it's not live data? Or do you have a search tool I should be using?
