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 | $0.00294 | $0.00294 |
| Opus 5 | $0.00147 | $0.00147 |
| Sonnet 5 | $0.00059 | $0.00059 |
| Haiku 4.5 | $0.00029 | $0.00029 |
Grade A, and why
modus-angular-checkbox-value-inversion-short 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.
What it actually says
Modus Checkbox Value Inversion - Short
Critical bug fix for ModusWcCheckbox value property inversion.
Key Rules
- Always invert checkbox value property -
const actualChecked = !valuefrominputChangeevent - Use wrapper components - Create Angular wrapper to handle inversion automatically
- Never trust the raw value - The
valueproperty is inverted (false when checked, true when unchecked) - Handle in event handlers - Invert value in
(inputChange)event handler - Test thoroughly - Verify checkbox behavior matches expected state
Bug Details
- When checkbox is checked:
target.valuereturnsfalse - When checkbox is unchecked:
target.valuereturnstrue
Correct Pattern
handleChange(event: CustomEvent<InputEvent>): void {
const value = (event.target as HTMLModusWcCheckboxElement).value;
const actualChecked = !value; // CRITICAL: Always invert
this.isChecked.set(actualChecked);
}

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.
