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 | $0.00059 | $0.02693 |
| Opus 5 | $0.00030 | $0.01347 |
| Sonnet 5 | $0.00012 | $0.00539 |
| Haiku 4.5 | $0.00006 | $0.00269 |
Grade A, and why
avalonia-controls-data-display 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 5d 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.

Avalonia Data Display Controls
Overview
Data display controls render read-only or selectable information. Prefer ItemsControl for simple lists, ListBox when selection is needed, DataGrid for tabular data, and TreeView for hierarchical data.

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-controls-data-display is a skill published in the GitHub repository linuxdevel/Avalonia-skills (36 stars, last pushed 4mo ago), licensed MIT. It adds 59 tokens to every session and 2,693 once invoked, about $0.0003 per session on Opus 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 2026-08-30.
