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 | $0.00054 | $0.01353 |
| Opus 5.5 | $0.00022 | $0.00541 |
| Sonnet 5.5 | $0.00011 | $0.00271 |
| Haiku 4.5 | $0.00005 | $0.00135 |
Grade A, and why
combobox 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.
How it starts
The opening of the file, as written. The whole thing — 95 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Combo box
Searchable dropdown for picking one or several options. Options can come from an association, an enumeration or boolean attribute, a database list, or a fixed list of static values.
When to use
- Use Combo box when the user picks a value in a form from a list of options: an associated object, an enumeration value, a boolean, or a fixed set of values.
- Use Combo box when the list is long or the user needs to search in it. It filters as the user types and loads options lazily.
- Use Combo box when the user must pick several objects for a reference set.
- Prefer radio buttons when there are only 2 to 4 options and all of them should be visible at once.
- Prefer a check box for a single yes/no boolean, unless the user asks for a dropdown.
- Do not use Combo box to browse, compare or act on records. Use Data grid 2 or Gallery for that.
Choosing the data source
Decide source first. Every other property depends on it.
| The user wants to pick... | source |
Then set |
|---|---|---|
| An associated object (one, or several) | context |
optionsSourceType = association |
| A value of an enumeration attribute | context |
optionsSourceType = enumeration |
| Yes/No for a boolean attribute | context |
optionsSourceType = boolean |
| Objects from a list, without an association to set | database |
optionsSourceDatabaseDataSource |
| One of a few fixed values written at design time | static |
staticAttribute + optionsSourceStaticDataSource |

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.

combobox is a skill published in the GitHub repository mendix/web-widgets (40 stars, last pushed today), licensed Apache-2.0. It adds 54 tokens to every session and 1,353 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-10-14.
