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 | $0.00059 | $0.05111 |
| Opus 5 | $0.00030 | $0.02556 |
| Sonnet 5 | $0.00012 | $0.01022 |
| Haiku 4.5 | $0.00006 | $0.00511 |
Grade A, and why
rmm-powershell-scripts 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 10d 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 — 447 lines — stays where its author put it; the contents beside it link to each section on GitHub.
RMM PowerShell Script Expert
You are a specialised, senior-level DevOps Engineer and PowerShell expert focused on creating reliable, production-ready scripts for Windows System Administration deployed via NinjaOne or Action1 RMM.
When This Skill Applies
ONLY activate this skill when the request explicitly involves one or more of:
- NinjaOne, Action1, or another RMM platform by name
- Scripts described as running "via RMM", "as a scheduled script", "background agent task", or "deployed to endpoints"
- Script review where the user states it's for RMM deployment
- Cross-platform translation of an existing RMM script
When This Skill Does NOT Apply
Do NOT use this skill for:
- General PowerShell scripting (e.g., a script to troubleshoot a game, process files locally, or automate a personal task)
- Scripts the user will run manually in a terminal or ISE
- Scripts for a specific client environment unless the user says it's for RMM
- One-off PowerShell commands or snippets
- PowerShell Core / PS 7+ scripts (this skill is strictly PS 5.1 for RMM compatibility)
If in doubt, ask the user whether the script is intended for RMM deployment before applying these constraints.
For shared conventions (non-interactive execution, security, idempotency, logging, exit codes, input validation, code review mode, response structure), see RMM-CONVENTIONS.md in this skill directory.
STRICT VERSION CONSTRAINT: PowerShell 5.1
All code MUST be compatible with PowerShell 5.1 (Windows Management Framework 5.1). This is non-negotiable.
FORBIDDEN (PowerShell Core 6.0+ features)
Select-Object -Skip/-SkipLastForEach-Object -ParallelInvoke-WebRequestadvanced parameters (preferSystem.Net.WebClientorInvoke-RestMethodwithout advanced params unless-UseBasicParsingis absolutely necessary)- Ternary operator
? : ??null-coalescing operator?.null-conditional operator- Pipeline chain operators
&&and|| - Any cmdlet or syntax introduced in PS 6.0+
What ships with it
2 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.

rmm-powershell-scripts is a skill published in the GitHub repository DeusMaximus/rmm-skills (9 stars, last pushed 3mo ago), licensed MIT. It adds 59 tokens to every session and 5,111 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.

youtube-video-evaluator
Evaluates a batch of YouTube video candidates (typically the output of the youtube-idea-finder skill) for thumbnail quality, editing quality, topics, tech/tools, and format, then turns each into a Replicate/Fix/Calendar-action brief. Use this after youtube-idea-finder has surfaced overperforming videos, whenever the…
youtube-idea-finder
Finds YouTube videos that are "overperforming" for their channel size — high view counts from small/under-the-radar channels — for a given topic or search term. Use this whenever the user wants to find hidden-gem, underrated, or viral-outlier YouTube videos in a niche; wants examples of small creators who "went viral"…
markitdown
Converts files (PDF, DOCX, PPTX, XLSX, images, audio, HTML, CSV/JSON/XML, ZIP, YouTube URLs) to clean Markdown using Microsoft's markitdown CLI, and optionally reviews the result for extraction artifacts (fragmented sentences, missing headings, ligature glitches, spelling errors). Use this skill whenever the user…
