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 | $0.00057 | $0.00538 |
| Opus 5.5 | $0.00023 | $0.00215 |
| Sonnet 5.5 | $0.00011 | $0.00108 |
| Haiku 4.5 | $0.00006 | $0.00054 |
Grade A, and why
avalonia-api-docs 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 2mo 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 API Docs
Workflow
-
Prefer project-local package documentation over web search.
- Read the project's
obj/project.assets.jsonto get the exact Avalonia package versions and NuGet package folder. - For HaloCreek, the current restored packages are under the Windows NuGet cache path recorded in
project.assets.json, for exampleC:\Users\cuika\.nuget\packages\, which is/mnt/c/Users/cuika/.nuget/packages/from WSL. - Prefer
ref/<target-framework>/*.xmlfor API surface documentation; fall back tolib/<target-framework>/*.xml.
- Read the project's
-
Use the bundled search script for API lookup:
python3 .codex/skills/avalonia-api-docs/scripts/search_avalonia_docs.py WindowStartupLocation
python3 .codex/skills/avalonia-api-docs/scripts/search_avalonia_docs.py ShowDialog Window
python3 .codex/skills/avalonia-api-docs/scripts/search_avalonia_docs.py --list-files
-
If the local XML docs are missing, run restore/build first if appropriate for the task. In HaloCreek, prefer the repository build skill for build validation.
-
Use online docs only as secondary context:
- API reference:
https://api-docs.avaloniaui.net/ - Concept docs:
https://docs.avaloniaui.net/ - Check the displayed version. Do not assume online API pages match the project's restored package version.
- API reference:
-
When an API remains ambiguous, inspect the referenced assemblies or source package rather than guessing. If the API field, enum value, overload, or XAML syntax cannot be verified, report that explicitly.
Practical Notes
- HaloCreek targets
net10.0and currently references Avalonia12.0.3; the local package XML is the most reliable source for that exact API surface. - Common XML files are
Avalonia.Controls.xml,Avalonia.Base.xml,Avalonia.Markup.Xaml.xml,Avalonia.Desktop.xml, andAvalonia.Themes.Fluent.xml. - The script searches XML member names and documentation text, then prints member IDs and compact summaries. Use the member ID to locate exact overloads.
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.

avalonia-api-docs is a skill published in the GitHub repository xianyu603/HaloCreek (1 stars, last pushed 2mo ago), licensed MIT. It adds 57 tokens to every session and 538 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-08-31.
