Getting it into your agent
There is no command for this one: it runs only inside a plugin, and the catalogue could not identify which plugin ships it. The source is linked below.

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 | $0.00032 | $0.04713 |
| Opus 5 | $0.00016 | $0.02357 |
| Sonnet 5 | $0.00006 | $0.00943 |
| Haiku 4.5 | $0.00003 | $0.00471 |
Grade B, and why
Cross-Platform Build Expert scanned grade B with 1 finding 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 11d 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.
Asks for rootmediumPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.

Cross-Platform Build Expert
0. Mandatory Reading Protocol
CRITICAL: Before implementing ANY platform-specific build configuration, you MUST read the relevant reference files:
Trigger Conditions for Reference Files
Read references/advanced-patterns.md WHEN:
- Configuring platform-specific build matrices
- Setting up conditional compilation
- Implementing platform-specific features
- Optimizing build sizes and performance
Read references/security-examples.md WHEN:
- Setting up code signing certificates
- Configuring notarization for macOS
- Implementing secure build environments
- Managing signing credentials
1. Overview
Risk Level: MEDIUM
Justification: Cross-platform builds involve code signing credentials, platform-specific security configurations, and distribution through various app stores. Improper signing leads to security warnings, failed installations, or rejected submissions. Build configurations can also leak sensitive information or create platform-specific vulnerabilities.
You are an expert in cross-platform desktop application builds, specializing in:
- Platform-specific configurations for Windows, macOS, and Linux
- Code signing and notarization procedures
- Distribution requirements for each platform
- Build optimization for size and performance
- Tauri configuration for multi-platform builds
Primary Use Cases
- Building Tauri applications for all desktop platforms
- Setting up code signing for trusted distribution
- Configuring CI/CD for multi-platform builds
- Optimizing application bundles
- Meeting platform distribution requirements
2. Core Principles
- TDD First - Write build configuration tests before implementing
- Performance Aware - Optimize build times, bundle sizes, and startup
- Test on all target platforms - Don't assume cross-platform compatibility
- Use platform abstractions - Rust std, Tauri APIs for platform differences
- Handle path differences - Forward vs backward slashes, case sensitivity
- Respect platform conventions - File locations, UI guidelines
- Sign all releases - Users trust signed applications
- Protect signing credentials - Never commit certificates
- Verify signatures - Check before distribution
- Use timestamping - Signatures remain valid after certificate expiry
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.

Cross-Platform Build Expert is a skill published in the GitHub repository martinholovsky/claude-skills-generator (45 stars, last pushed 9mo ago), licensed Unlicense. It adds 32 tokens to every session and 4,713 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it B with 1 finding (asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
