Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00166 | $0.01932 |
| Opus 5.5 | $0.00066 | $0.00773 |
| Sonnet 5.5 | $0.00033 | $0.00386 |
| Haiku 4.5 | $0.00017 | $0.00193 |
Grade A, and why
powershell-master 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 1mo 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.
How it starts
The opening of the file, as written. The whole thing — 190 lines — stays where its author put it; the contents beside it link to each section on GitHub.
PowerShell Master
Complete PowerShell expertise across all platforms for scripting, automation, CI/CD, and cloud management.
When to Activate
PROACTIVELY activate for ANY PowerShell-related task:
- PowerShell Scripts - Creating, reviewing, optimizing any .ps1 file
- Cmdlets & Modules - Finding, installing, using any PowerShell modules
- Cross-Platform - Windows, Linux, macOS PowerShell tasks
- CI/CD Integration - GitHub Actions, Azure DevOps, Bitbucket Pipelines
- Cloud Automation - Azure (Az), AWS, Microsoft 365 (Microsoft.Graph)
- Module Management - PSGallery search, installation, updates
- Script Debugging - Troubleshooting, performance, security
- Best Practices - Code quality, standards, production-ready scripts
Usage
| You say | What happens |
|---|---|
"Write/review this .ps1 script" |
Runs the Core Workflow below — identifies scope/platform, checks $PSVersionTable, loads only the reference file(s) the task actually needs, applies the Pre-Flight Checklist before finalizing. |
"Set up a GitHub Actions/Azure DevOps pipeline for this" |
Loads references/cicd-integration.md for multi-platform build/test matrix patterns. |
"Automate this in Azure/AWS/Microsoft 365" |
Loads references/modules-and-gallery.md — Az, Microsoft.Graph, AWS Tools, PSGallery install guidance. |
"Is this script secure? How do I handle credentials?" |
Loads references/security-2025.md — JEA, WDAC, Constrained Language Mode, Script Block Logging, credential handling, code signing. |
"Why is this slow / how do I write a Pester test?" |
Loads references/syntax-reference.md — cmdlet reference, pipeline, error handling, Pester, performance tuning. |
"This needs to run on Windows and Linux" |
Loads references/cross-platform-patterns.md — $IsWindows/$IsLinux/$IsMacOS, path handling, encoding, shell detection. |
Reference Map
Detailed material lives in references/. Load only what the current task needs.
What ships with it
5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
