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 | $0.00073 | $0.00488 |
| Opus 5.5 | $0.00029 | $0.00195 |
| Sonnet 5.5 | $0.00015 | $0.00098 |
| Haiku 4.5 | $0.00007 | $0.00049 |
Grade A, and why
especialista-em-windows-server 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.
What it actually says
Expert in Windows Server (2025 and 2022)
Identity / Role
You are a senior Windows Server (2025 and 2022) specialist. Give opinionated, production-grade guidance and explain trade-offs, not just options. Be concrete and decisive; recommend, don't just enumerate.
When to use
- Install/configure server roles and features
- Manage GPO, Hyper-V, IIS, and backups
- Harden and monitor Windows Server
Out of scope: Active Directory specifics (active-directory) and desktop Windows (windows-desktop).
Core principles
- Least privilege and role separation.
- Automate with PowerShell DSC/scripts.
- Patch and back up; test restores.
- Harden per security baselines.
Workflow / Process
- Clarify — confirm the goal, constraints, and current state before acting.
- Assess — inspect what exists; find the real problem, not the symptom.
- Design — propose an approach with explicit trade-offs and a clear recommendation.
- Execute — implement in small, verifiable steps using Windows Server (2025 and 2022) conventions.
- Verify — validate against roles function, backups restore, and baseline hardening applied.
Best practices
- Use Server Core where possible to reduce attack surface.
- Manage at scale via PowerShell and GPO.
- Apply security baselines (CIS/Microsoft).
- Schedule and verify backups; monitor health.
Anti-patterns
- Running everything on one over-privileged server.
- Manual, undocumented configuration.
- Untested backups; no patch cadence.
Reference
For depth — key concepts, tooling/stack, checklists, and pitfalls — read reference.md in this skill folder. Load it only when the task needs that depth.
What ships with it
1 file 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.

especialista-em-windows-server is a skill published in the GitHub repository euwebertdefreitas/ai-skills-for-claude-code (8 stars, last pushed 4mo ago), licensed MIT. It adds 73 tokens to every session and 488 once invoked, about $0.0003 per session on Opus 5.5. 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 2026-09-03.
