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.

SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- medium Excessive Agency · line 4 Skill selects an external model or provider that may use a different account or billing plan than the operator expects. Undisclosed model switches can cause unexpected cost or quota consumption.Fix: Remove the model/provider override or disclose it prominently and require explicit operator approval before invoking an external coding CLI or billed model.
What it costs to keep this loaded
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 | $0.00026 | $0.01462 |
| Opus 5 | $0.00013 | $0.00731 |
| Sonnet 5 | $0.00005 | $0.00292 |
| Haiku 4.5 | $0.00003 | $0.00146 |
Grade A, and why
implementing-wpf-automation 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.

WPF UI Automation Patterns
Implementing accessibility features using UI Automation framework.
Prerequisites
When implementing AutomationPeer for a CustomControl, ensure the control project is properly set up:
- ThemeInfo attribute in AssemblyInfo.cs → See
/configuring-wpf-themeinfo - CustomControl project structure → See
/authoring-wpf-controls - DefaultStyleKeyProperty in static constructor

<!-- Name for image buttons (no text content) -->
<Button AutomationProperties.Name="Close window">
<Image Source="/Icons/close.png"/>
</Button>
<!-- HelpText - additional description -->
<TextBox AutomationProperties.Name="Email address"
AutomationProperties.HelpText="Enter your email in format [email protected]"/>
<!-- LabeledBy - reference to label element -->
<Label x:Name="UsernameLabel" Content="Username:"/>
<TextBox AutomationProperties.LabeledBy="{Binding ElementName=UsernameLabel}"/>
2.2 Additional Properties
<!-- AcceleratorKey - keyboard shortcut hint -->
<Button Content="_Save"
AutomationProperties.AcceleratorKey="Ctrl+S"/>
<!-- AccessKey - mnemonic key -->
<Button Content="_File"
AutomationProperties.AccessKey="Alt+F"/>
<!-- ItemStatus - current state information -->
<ListBoxItem AutomationProperties.ItemStatus="Selected, 3 of 10"/>
<!-- ItemType - type description for list items -->
<ListBoxItem AutomationProperties.ItemType="Email message"/>
<!-- LiveSetting - for dynamic content updates -->
<TextBlock AutomationProperties.LiveSetting="Polite"
Text="{Binding StatusMessage}"/>
What ships with it
1 file 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.

implementing-wpf-automation is a skill published in the GitHub repository christian289/dotnet-with-claudecode (41 stars, last pushed 1mo ago), licensed MIT. It adds 26 tokens to every session and 1,462 once invoked, about $0.0001 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.
