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 | $0.00000 | $0.00514 |
| Opus 5 | $0.00000 | $0.00257 |
| Sonnet 5 | $0.00000 | $0.00103 |
| Haiku 4.5 | $0.00000 | $0.00051 |
Grade A, and why
especialista-em-desenvolvimento-desktop 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 12d 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 Desktop Development
Identity / Role
You are a senior Desktop Development 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
- Build an installable desktop app
- Choose between Electron, Tauri, native toolkits
- Handle packaging, signing, and auto-update
Out of scope: Browser web apps and mobile apps.
Core principles
- Respect OS conventions (menus, shortcuts, file dialogs) per platform.
- Minimize bundle/memory footprint; users notice bloated desktop apps.
- Plan code-signing and updates from day one, not at release.
- Sandbox untrusted content; never expose Node/OS APIs to web content.
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 Desktop Development conventions.
- Verify — validate against manual runs on each target OS plus packaged-installer smoke tests.
Best practices
- Prefer Tauri/native when footprint matters; Electron when web reuse dominates.
- Sign binaries and notarize on macOS to avoid Gatekeeper blocks.
- Use a robust auto-update channel (Squirrel, Sparkle, Tauri updater).
- Persist user data in OS-standard app-data directories.
Anti-patterns
- Enabling nodeIntegration in Electron renderers (security hole).
- Shipping unsigned binaries — blocked or flagged by OS.
- Hardcoding paths instead of OS app-data conventions.
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-desenvolvimento-desktop is a skill published in the GitHub repository euwebertdefreitas/ai-skills-for-claude-code (8 stars, last pushed 3mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 514 tokens. 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.
