kx-query

kx-query is a skill for Claude Code from KxSystems/kx-skills. It costs 69 tokens per session (1,069 once invoked), scanned A, original, Apache-2.0.

A guide for creating data sources in KX Dashboards, which are screens that display live or queried data. It covers kdb+, a database and query language for time-based data, and SQL, a common language for retrieving database records.

In plain words
What is it for?
Building charts, tables, forms, maps, and dashboard actions from queried, polled, or streaming data. It also helps connect query results to dashboard controls and widgets.
Why use it?
It helps prevent invalid queries, incorrect parameter wiring, and broken links between data and dashboard widgets.

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

kx-query 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 10d 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.

KX Query & Data Sources

Depends on kx-dashboard-core for the dashboard envelope, ViewState schema, and binding patterns.

This skill uses progressive disclosure: the hazards, workflow, and validation rules are here; the connection/data-source JSON schemas, query patterns, pivot config, reserved-word list, and dashboard-oriented q snippets live in reference/. Read only the reference file relevant to your current step.

Reference Files

File Read it when you need…
reference/schema.md The connection file format, _dataType/_subscriptionType values, and the full JSON template for every data source kind (query, analytic, virtual, pykx, polling, streaming, update query, ViewState params).
reference/query-patterns.md kdb+ query idioms, filtering by ViewState type (symbol / string like / list), component-side binding, and symbol-vs-string handling.
reference/pivot-grid.md The Pivot Grid data source (key: "Datatable") — pivot attributes, _layout, _mappings, and the full template.
reference/reserved-words.md The reserved-word list and the validation algorithm to run before accepting any kdb+ query string.
reference/q-language.md Dashboard-oriented q snippets only — the few q patterns that matter specifically when writing KX Dashboards data sources (not general q fundamentals like operators, iterators, system commands, or data types).

⚠️ Hazards

  1. Always write both _autoExecute and _autoExec — some versions only honour one.
  2. _connection must match the connection file name field exactly (case-sensitive).
  3. _subscriptionType: "streaming" requires a streaming-capable connection — don't use it with static kdb+ processes.
  4. ViewState param value must use the template syntax (<%group/name%> or <%name%>), not a raw value.
  5. _dataType: "pykx" requires PyKX to be installed on the kdb+ process.
  6. Polling interval is in seconds (_subscriptionInterval). Minimum meaningful value is 1.
  7. Reserved words must never appear as assignment targets — assigning to a reserved word (e.g. sum: 5) raises 'assign at runtime. Run reserved-word validation before accepting any query. See the Reserved Word Validation section below.
  8. Analytics run a named function, not a query. _selectedAnalytic is a dotted kdb+ function name (e.g. .fx.sub), not a table. A streaming analytic must copy its _analyticParams into _streamingParameters (identical) — the subscription reads its arguments from _streamingParameters. See the Analytic Data Source section in reference/schema.md.

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-query is a skill published in the GitHub repository KxSystems/kx-skills (16 stars, last pushed 8d ago), licensed Apache-2.0. It adds 69 tokens to every session and 1,069 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.
