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 | $0.00360 | $0.00360 |
| Opus 5 | $0.00180 | $0.00180 |
| Sonnet 5 | $0.00072 | $0.00072 |
| Haiku 4.5 | $0.00036 | $0.00036 |
Grade A, and why
modus-checkbox-value-inversion-solidjs-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 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.
What it actually says
Modus Checkbox Value Inversion - Short
Critical bug fix for ModusWcCheckbox value property inversion.
Key Rules
- Use the
ModusCheckboxwrapper - It handles the value inversion bug automatically - The wrapper prop is
value, NOTchecked-<ModusCheckbox value={isChecked()} />(usingcheckedwill fail silently) - Use
onValueChangecallback - It provides the corrected boolean viaevent.detail(already inverted by the wrapper) - Never use raw
modus-wc-checkboxdirectly - The raw web component'svalueproperty is inverted (false when checked, true when unchecked) - Indeterminate state - Pass
indeterminate={true}for partial selection (e.g., select-all checkbox when some items are checked)
DO: Use the wrapper with correct props
<ModusCheckbox
value={isSelected()}
indeterminate={isSomeSelected()}
onValueChange={(e) => setSelected(e.detail)}
size="sm"
/>
DON'T: Common mistakes
// DON'T: "checked" prop does not exist on the wrapper
<ModusCheckbox checked={isSelected()} />
// DON'T: Use raw web component without inversion handling
<modus-wc-checkbox value={isChecked()} />

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.
