pipeline-dev

pipeline-dev is a skill for Claude Code from KxSystems/kx-skills. It costs 115 tokens per session (1,080 once invoked), scanned A, original, Apache-2.0.

A guide for writing KDB Stream Processor pipelines in q or Python. A pipeline connects data sources, processing steps, and destinations, such as Kafka, cloud storage, databases, or streams.

In plain words
What is it for?
Use it when creating streaming data pipelines, connecting readers and writers, adding filters or windows, or configuring Kafka, S3, database, and machine-learning steps.
Why use it?
It reduces mistakes when choosing pipeline inputs, outputs, transformations, and operator syntax.

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

pipeline-dev 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 8d 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.

SP Pipeline Writer

A pipeline is a DAG: readers → operators → writers, chained in q with bracket notation or in Python with |.


Step 1 — Clarify (required before generating)

Before writing any code, confirm all four of these. Ask together in a single message for anything not already stated:

# What to confirm Examples
1 Source Kafka, S3, HTTP, callback, database, expression
2 Sink stream, database, Kafka, console, variable
3 Language q, Python, or both
4 Transform filter, map, window, join, ML, schema rename, none

Do not generate a pipeline until all four are clear. If the user's request answers some but not all, ask only about the gaps. Skip optional details (schema registry, auth) unless the user raises them.


Step 2 — Look up operator signatures

Don't guess API signatures — fetch them before generating code.

Primary: kx-docs MCP (use mcp__kx-docs__search_kx_knowledge_sources if available):

"SP readers fromKafka fromAmazonS3"
"SP writers toDatabase toStream toKafka"
"SP decode encode avro json csv"
"SP operators map filter apply merge split"
"SP window tumbling sliding"
"SP transform renameColumns replaceNull"
"SP ml minMaxScaler"

Fallback: public docs (if MCP unavailable — switch silently, only report if both fail):

map / filter / apply / merge / split operators.html
Window operators windows.html
Transform utilities transform.html
ML operators ml.html
.qsp.use / operator config configuring-operators.html

Step 3 — Generate the pipeline

Hard rules:

  • .qsp.run / sp.run(..) called exactly once
  • Readers have no upstream nodes; writers have no downstream nodes
  • In q: always bracket notation (.qsp.map[fn]) — never prefix form
  • Operator config via .qsp.use in q; keyword args in Python
  • Prefer v2 namespace when available (.qsp.v2.read.fromAmazonS3, api_version=2 in Python)

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.

pipeline-dev is a skill published in the GitHub repository KxSystems/kx-skills (16 stars, last pushed 6d ago), licensed Apache-2.0. It adds 115 tokens to every session and 1,080 once invoked, about $0.0006 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.
