Token cost

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.

Security

Grade A, and why

dropdown-select 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.

What it actually says

When to Use What

Options Pattern Why
2-3 Radio buttons or segmented control All options visible
4-7 Dropdown select Manageable list
8-15 Dropdown with search Finding options quickly
15+ Combobox (searchable input) Must be able to search
Multi-select needed Checkbox list or tag input Clear selection state
  • Max visible items: 6-8 (then scroll)
  • Selected item shown in the trigger
  • Checkmark or highlight on selected item
  • Keyboard navigation: type to jump, arrows to move, Enter to select
  • Group long lists into labeled sections
  • Close on selection (single-select) or have an explicit "Done" (multi-select)

Combobox

  • Filter results as user types
  • Highlight matching text in results
  • Allow custom values if appropriate
  • Show "no matches" state with suggestions
  • Clear button to reset selection

Multi-Select

  • Show selected count in trigger ("3 selected")
  • Show selected items as tags/chips that can be individually removed
  • "Select all" and "Clear all" for long lists
  • Don't close on selection (users need to select multiple)

Accessibility

  • role="listbox" for the options container
  • role="option" for each item
  • aria-selected for current selection
  • aria-expanded on the trigger
  • Full keyboard support (Tab, Arrow, Enter, Escape)
Changes

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.
