Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

powershell-windows scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

PowerShell Windows - Scripting Rules

Essential rules for correct PowerShell usage on Windows. Follow these rules to avoid common errors when executing shell commands.

Core Principles

1. Command Separation

  • Wrong: cd "path" && command (bash syntax)
  • Correct: cd "path"; command (PowerShell syntax)

2. Path Quoting

  • Always use double quotes for paths with spaces: 
    cd "D:\My Projects\MyApp"

3. Script Execution

  • For .bat/.cmd files: 
    ./gradlew clean build
.\gradlew.bat clean build

4. Docker Commands

  • Specify full path to docker-compose files: 
    docker-compose -f "D:\My Projects\app\docker-compose.yml" up -d

5. HTTP Requests

  • Wrong: curl -s http://localhost:9090/status
  • Correct: 
    Invoke-WebRequest -Uri "http://localhost:9090/status" -UseBasicParsing

6. Waiting/Delays

  • Wrong: timeout 10
  • Correct: 
    Start-Sleep -Seconds 10

7. JSON Handling

  • JSON parsing: 
    $response = Invoke-WebRequest -Uri "http://localhost:9090/status" -UseBasicParsing
$json = $response.Content | ConvertFrom-Json
$json | ConvertTo-Json -Depth 3

8. Process Checking

  • Process search: 
    Get-Process -Name "java" -ErrorAction SilentlyContinue

9. Docker Operations

  • Stop containers: 
    docker-compose -f "path\to\file.yml" down
  • Build images: 
    docker-compose -f "path\to\file.yml" build --no-cache

10. Error Handling

  • Ignore errors: 
    Get-Process -Name "java" -ErrorAction SilentlyContinue

Common Errors and Fixes

Error Cause Fix
&& is not recognized Using bash syntax Replace && with ;
curl not found curl not installed on Windows Use Invoke-WebRequest
timeout not found timeout not supported Use Start-Sleep
Path not found Missing quotes on spaced path Wrap path in double quotes

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
