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 | $0.00020 | $0.00499 |
| Opus 5 | $0.00010 | $0.00249 |
| Sonnet 5 | $0.00004 | $0.00100 |
| Haiku 4.5 | $0.00002 | $0.00050 |
Grade A, and why
avalonia-zafiro-development 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 4d 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.
This is a copy
86% identical to avalonia-zafiro-development — 11 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Avalonia Zafiro Development
This skill defines the mandatory conventions and behavioral rules for developing cross-platform applications with Avalonia UI and the Zafiro toolkit. These rules prioritize maintainability, correctness, and a functional-reactive approach.
Core Pillars
- Functional-Reactive MVVM: Pure MVVM logic using DynamicData and ReactiveUI.
- Safety & Predictability: Explicit error handling with
Resulttypes and avoidance of exceptions for flow control. - Cross-Platform Excellence: Strictly Avalonia-independent ViewModels and composition-over-inheritance.
- Zafiro First: Leverage existing Zafiro abstractions and helpers to avoid redundancy.
Guides
- Core Technical Skills & Architecture: Fundamental skills and architectural principles.
- Naming & Coding Standards: Rules for naming, fields, and error handling.
- Avalonia, Zafiro & Reactive Rules: Specific guidelines for UI, Zafiro integration, and DynamicData pipelines.
- Zafiro Shortcuts: Concise mappings for common Rx/Zafiro operations.
- Common Patterns: Advanced patterns like
RefreshableCollectionand Validation.
Procedure Before Writing Code
- Search First: Search the codebase for similar implementations or existing Zafiro helpers.
- Reusable Extensions: If a helper is missing, propose a new reusable extension method instead of inlining complex logic.
- Reactive Pipelines: Ensure DynamicData operators are used instead of plain Rx where applicable.
When to Use
This skill is applicable to execute the workflow or actions described in the overview.
Limitations
- Use this skill only when the task clearly matches the scope described above.
- Do not treat the output as a substitute for environment-specific validation, testing, or expert review.
- Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.
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.

avalonia-zafiro-development is a skill published in the GitHub repository beel-collab/presets.dev (2 stars, last pushed 4mo ago), licensed MIT. It adds 20 tokens to every session and 499 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. It is 86% identical to avalonia-zafiro-development, differing in 11 lines, and is treated as a copy.
