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 | $0.00063 | $0.01389 |
| Opus 5 | $0.00032 | $0.00694 |
| Sonnet 5 | $0.00013 | $0.00278 |
| Haiku 4.5 | $0.00006 | $0.00139 |
Grade A, and why
kx-formbuilder 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 9d 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 — 71 lines — stays where its author put it; the contents beside it link to each section on GitHub.
KX FormBuilder Component
Also read kx-dashboard-core for: envelope, screen/widget wrapper, data sources, ViewState, binding patterns, actions, notifications, and the pre-flight checklist.
This skill uses progressive disclosure: the workflow, hazards, and output rules are here; the bulky JSON schema, field/validator/style tables, and examples live in reference/. Read only the reference file relevant to your current step.
Reference Files
| File | Read it when you need… |
|---|---|
| reference/component-schema.md | The raw component JSON — full options envelope, Basics, Elements field object, all kdb Field Types (incl. list dropdown and group), Validators, Style, Actions, and StateOutput. |
| reference/examples.md | A full worked Trade Entry Form plus 5 few-shot NLQ → JSON examples. |
| reference/nlq-tests.md | Maintainer NLQ regression queries to retest on every MR that changes this skill. |
When to Use This Skill
- User wants a form widget that collects values from dashboard users
- User wants to bind form field values to ViewStates and re-execute queries on submit
- User wants a dynamic form whose schema is driven by a live kdb+ query (
FormDefinition) - User wants to trigger actions (map, navigate, re-execute query) on Submit, Cancel, or Change events
- User wants to write form values back to a ViewState via
StateOutput
⚠️ FormBuilder-Specific Hazards
- Element
idmust be unique across all Elements including nested groups. Duplicate ids silently overwrite each other in the output values object. type._Typeis the kdb type string —symbol,int,float,date,list,group, etc. Never settypeto a plain string; it must always be an object with_Type.listis the dropdown type, not a kdb list. To present a dropdown to the user, settype._Typeto"list". The output value type is recorded as"symbol".passwordonly applies tosymbolfields. Settingpassword: trueon any other type has no effect.groupfields carry their child fields in a nestedElementsarray, not undertype. The group's owntype._Typeis"group"with an optionallayoutsub-property.- Actions
Triggervalues are"Submit","Cancel","Change"— not"Click". Using"Click"will silently do nothing. StateOutputTrigger fires a map action that writes the entire form's current values to the target ViewState.Currentis auto-populated; only setTarget.FormDefinitionbinding overridesElements. WhenBasics.FormDefinitionis bound to a ViewState, the properties panel hides the Elements editor and the form schema comes entirely from kdb.FormValuesis a two-way binding. It can pre-populate fields on load (if the ViewState has values) and receives the latest form values after every change.ignoreOnChangeexcludes a field from theChangetrigger output but not fromSubmitorCancel. Use it for UI-only controls that shouldn't re-trigger queries on every keystroke.
What ships with it
3 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.

kx-formbuilder is a skill published in the GitHub repository KxSystems/kx-skills (16 stars, last pushed 7d ago), licensed Apache-2.0. It adds 63 tokens to every session and 1,389 once invoked, about $0.0003 per session on Opus 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.
