AI skills for internet and game troubleshooting.

Content updated November 5, 2026

If you'd like help running checks and reading the output, an AI agent on your PC can walk through them with you. Take a look at a real report before setting anything up.

See how it went on one PC

Which Wi-Fi network should I use from this room? follows three connections on one PC. See what the checks found, why they could not explain the Teams problem, and how the chosen connection worked afterward.

Read the actual agent report for observations, uncertainty, and next checks. No installation or account is needed to read it.

Continue without an agent: compare Wi-Fi connections, investigate call symptoms, choose another symptom, or run the optional browser check.

Pick a skill for the problem

internet-diagnostics: Investigates connection symptoms: Wi-Fi, DNS, VPNs, delay under load, buffering, and calls. Supports Windows, macOS, and Linux.
game-diagnostic: Investigates low FPS, stutter, input delay, rubber-banding, crashes, and loading stalls. Starts with read-only checks to distinguish PC performance problems from network delay.
game-optimizer: Measures performance before and after one change you approve. Helps you compare results and restore the original setting if needed.

A skill gives the agent instructions to follow. It may still leave the cause unresolved or find no improvement to make. The gaming skills also work on Windows, macOS, and Linux. Optional capture tools need a separate installation.

Start with an agent on your PC.

An agent is an AI app that can work with local files and run commands with your permission. Optional examples include Codex, Claude Code, Cursor, or GitHub Copilot in agent mode. Setup and capabilities vary. A browser chat alone cannot run checks on your PC.

Other agents you can look into

OpenCode: Check its current setup instructions, supported models, and provider terms.
Kilo Code: Check available model choices and current usage terms.
Freebuff: Review current availability, setup, and data policy before sharing diagnostic details.

Pricing, limits, and data policies vary by provider. Review them before use. Installer support varies by agent. Use the manual instructions if yours isn't listed.

Install your chosen skill.

Paste this into your local agent's chat:

Install https://github.com/jvickusa/tech-support-skills

Prefer a terminal? With Node.js (includes npm/npx) and Git installed, open a terminal in the folder you'll use with your agent and run:

Your PC's terminal · Downloads and installs agent skills

npx skills add jvickusa/tech-support-skills

Runs only when you paste it into your terminal and press Enter.

Select internet-diagnostics, game-diagnostic, or game-optimizer for your question, then select your agent when prompted. Installation applies to the current folder by default. Open your agent in that same folder. Refresh or restart it if the skill doesn't appear.

Use the skill across projects

Your PC's terminal · Installs for your selected agent across projects

npx skills add jvickusa/tech-support-skills --global

Runs only when you paste it into your terminal and press Enter.

Tell your agent what's going wrong.

Paste one of these prompts into your agent's chat and adapt the symptom. You can also invoke $internet-diagnostics in Codex or /internet-diagnostics in Claude Code.

Games lag, speed looks fine

Use internet-diagnostics. My game lags when someone uploads, but my speed test looks good. I'm not technical. Explain each test and guide me one step at a time. Ask before changing any settings.

Calls freeze or streams buffer

Use internet-diagnostics. Video calls freeze and streams buffer on this PC. Help me compare Wi-Fi, upload activity, and the affected app. Start with read-only checks and explain what the evidence does and doesn't show.

Make sense of a connection check

Use internet-diagnostics to help interpret my result from whyismyinternetcrap.com. Ask me to paste the readings, then suggest checks on this PC. Write an HTML troubleshooting report with findings, uncertainty, and next steps. Ask before making changes.

A game starts stuttering

Use game-diagnostic. My game starts stuttering after ten minutes. Start with read-only checks, help me reproduce it, and compare frame timing with CPU, GPU, memory, storage, and power evidence. Explain what remains uncertain.

Test a game performance change

Use game-optimizer with my diagnostic findings. Help me improve frame pacing while preserving image quality. Establish a baseline, then prepare one reversible experiment with side effects and rollback. Ask permission before changing settings.

Tell the agent what you see and let it explain each check as you go. You can ask for a Markdown or offline HTML report to keep the findings or share them with support.

Review commands and changes

The skill starts with read-only checks and tells the agent to ask before changing settings or disconnecting a VPN. Review commands before approving them. Your agent may send diagnostic output to its model provider. Review its data policy before running checks or sharing logs.

Network names and addresses can appear in diagnostics. Redact them before sharing, and never include passwords or API keys. This site doesn't automatically send your connection results to an agent. Copy only the readings you want it to see.

Treat the findings as leads to follow up. They cannot prove which router, provider, or network hop caused the problem. Run a browser connection check or start with a troubleshooting guide.
