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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00224 | $0.03794 |
| Opus 5.5 | $0.00090 | $0.01518 |
| Sonnet 5.5 | $0.00045 | $0.00759 |
| Haiku 4.5 | $0.00022 | $0.00379 |
Grade A, and why
objectstack-ui 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 today.
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.

UI Design — ObjectStack UI Protocol
Expert instructions for designing user interfaces using the ObjectStack specification. This skill covers Views (list, form, kanban, calendar, …), App navigation, Dashboards, Reports, and Actions.
View Types
List Views
| Type | When to Use |
|---|---|
grid |
Standard data table — default for most objects |
kanban |
Visual board with columns (status-driven workflows) |
gallery |
Card-based masonry layout (visual catalogues, contacts) |
calendar |
Date-based scheduling (events, tasks, bookings) |
timeline |
Chronological activity stream |
gantt |
Project management with dependency tracking |
map |
Geospatial records with location fields |
chart |
Aggregate visualisation over the object (mini chart view) |
tree |
Self-referencing hierarchy (tree-grid) |
Form Views
| Type | When to Use |
|---|---|
simple |
Single-page form — suitable for objects with ≤ 15 fields |
tabbed |
Tabbed sections — for complex objects with many field groups |
wizard |
Step-by-step flow — guided data entry (onboarding, applications) |
Master-Detail Forms (parent + child line items)
To let users enter a record together with its child line items (invoice + lines, project + tasks) and save them atomically, you almost never need a custom page or form config. Prefer, in order:
-
Relationship
inlineEdit(default, zero UI config). Declare it in the DATA MODEL — setinlineEditon the child'smaster_detailfield that references the parent. Every standard New/Edit form for the parent (modal, drawer, full-page) then auto-renders the children and saves parent + children in one atomic/api/v1/batch. No view metadata needed. Thetrue/'grid'/'form'ladder and what each value picks: objectstack-data → Relationships → Inline Editing. -
Form view
subforms(override / tuning). Add to a form view only when you need to override the derived columns/order, or expose a child the relationship didn't mark inline:
What ships with it
10 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

objectstack-ui is a skill published in the GitHub repository objectstack-ai/objectstack (72 stars, last pushed today), licensed Apache-2.0. It adds 224 tokens to every session and 3,794 once invoked, about $0.0009 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 2026-08-30.
