What it does
Defender Quickscan is an agent skill from taracodlabs/aiden. Windows Defender: scans, threat history, signatures (PowerShell)
Its SKILL.md is about 750 tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `skill.json`).
It works with PowerShell. The repository describes itself as: Aiden — an autonomous AI agent and work engine built solo. It can operate your browser, terminal, files, apps, APIs, skills and tools, remember context, recover from failures… The licence is Apache-2.0.
Example prompts
- “Use the defender-quickscan skill to window Defender: scans, threat history, signatures (PowerShell)”
- “/defender-quickscan”
What it can do on your machine
Read from SKILL.md and the folder at commit 3704204. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are powershell).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Defender Quickscan loads about 751 tokens when it runs. Until then it costs about 21 tokens; SKILL.md has 218 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Defender Quick Scan
Trigger Windows Defender antivirus scans, inspect threat history, update virus definitions, and check real-time protection status — all via PowerShell cmdlets.
When to Use
- User wants to run a quick or full antivirus scan
- User asks about recent threats detected by Defender
- User wants to check if real-time protection is enabled
- User needs to update virus/malware signatures
- User wants to know the current Defender protection status
How to Use
Check Windows Defender status
Get-MpComputerStatus | Select-Object AMServiceEnabled, AntispywareEnabled,
AntivirusEnabled, RealTimeProtectionEnabled,
AntispywareSignatureAge, AntivirusSignatureAge, QuickScanAgeRun a quick or full scan
Start-MpScan -ScanType QuickScan # fast scan of likely threat locations
Start-MpScan -ScanType FullScan # thorough scan of all files (30-60 min)Scan a specific file or folder
Start-MpScan -ScanType CustomScan -ScanPath "C:\Users\<you>\Downloads"Update virus definitions

Remove-MpThreat -ThreatID 12345Check exclusion list
(Get-MpPreference).ExclusionPath
(Get-MpPreference).ExclusionExtensionAdd a scan exclusion (path)
Add-MpPreference -ExclusionPath "C:\DevTools\node_modules"Examples
"Scan my Downloads folder for threats"
→ Start-MpScan -ScanType CustomScan -ScanPath "$env:USERPROFILE\Downloads" — Defender scans the folder and logs any detections.
"Are my virus definitions up to date?"
→ Get-MpComputerStatus | Select-Object AntivirusSignatureAge, AntivirusSignatureLastUpdated — signature age of 0 means updated today.
"Show me the last 5 threats Defender found"
→ Get-MpThreatDetection | Sort-Object InitialDetectionTime -Descending | Select-Object -First 5
Cautions
- Full scans can take 30-60 minutes and consume significant CPU/IO — warn the user before running
Start-MpScanrequires Windows Defender to be the active antivirus — third-party AV may disable these cmdlets- Removing a threat with
Remove-MpThreatis permanent; confirm with the user before executing - Adding exclusions reduces protection coverage — only exclude paths you're certain are safe
