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 | $0.00070 | $0.03918 |
| Opus 5 | $0.00035 | $0.01959 |
| Sonnet 5 | $0.00014 | $0.00784 |
| Haiku 4.5 | $0.00007 | $0.00392 |
Grade A, and why
nylo-widgets 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 2d 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.

Nylo Built-in Widgets
Overview
Nylo v7 provides a rich widget library covering common UI patterns: toast notifications, bottom sheet modals, styled buttons with animation, list/grid rendering with pagination, async data display, pull-to-refresh, rich text, spacing, localization, and connectivity-aware layouts. These widgets integrate with Nylo's theme and state systems.
When to Use
- Showing toast notifications or alert dialogs
- Displaying bottom sheet modals
- Creating buttons with loading states, animations, or form submission
- Rendering lists or grids with pagination, sorting, and filtering
- Loading async data with loading/error states
- Adding pull-to-refresh to scrollable content
- Building rich text with mixed styles and tap handlers
- Adding consistent spacing between elements
- Translating text or switching languages
- Showing different UI based on network connectivity
- When NOT to use: for custom widgets unrelated to Nylo's built-in library, use standard Flutter widgets

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.
