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 0 findings 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 8d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

PowerShell Windows Engineering Patterns

Scope: Essential syntax, safety rules, and error-handling patterns for Windows PowerShell / PowerShell 7+.


🎯 Progressive Disclosure & L3 Reference Index

Read REQUIRED PowerShell rules below; consult deep L3 Reference Guides on demand:

L3 Reference Guide Purpose Trigger / When to Load
references/powershell_pitfalls_and_recipes.md JSON -Depth handling, process kills, Join-Path cross-drive safety Complex PowerShell scripting & automation

⚠️ 1. Top 4 Non-Negotiable Syntax Rules

  1. Parentheses for Cmdlets in Conditions:
    • if (Test-Path "a" -or Test-Path "b")
    • if ((Test-Path "a") -or (Test-Path "b"))
  2. ASCII Only in Logs/Scripts: Use ASCII status tags ([OK], [FAIL], [WARN]) instead of raw Unicode/emojis to prevent Windows codepage crashes.
  3. Always Specify -Depth on JSON: Always use ConvertTo-Json -Depth 20 to prevent truncation of nested objects.
  4. Safe Path Joining: Always use Join-Path or $PSScriptRoot instead of raw string concatenation.

🛡️ 2. Error Handling & Execution Policy

$ErrorActionPreference = "Stop"

try {
    # Execute operation
    cargo check --manifest-path server-rs/Cargo.toml
    Write-Host "[OK] Build verification succeeded"
} catch {
    Write-Error "[FAIL] Operation failed: $_"
    exit 1
}

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.
