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 | $0.00027 | $0.00386 |
| Opus 5 | $0.00014 | $0.00193 |
| Sonnet 5 | $0.00005 | $0.00077 |
| Haiku 4.5 | $0.00003 | $0.00039 |
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 9d 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
100% identical to avalonia-zafiro-development — 0 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.
What it actually says
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.
What ships with it
5 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.

avalonia-zafiro-development is a skill published in the GitHub repository cgyudistira/agentkit (2 stars, last pushed 7mo ago), licensed MIT. It adds 27 tokens to every session and 386 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to avalonia-zafiro-development, differing in 0 lines, and is treated as a copy.
