A setup guide for ktx, a context layer that connects data sources and embeddings to data-focused agents. It also installs the agent integration and checks whether the setup is ready.

Use it to add ktx to a project, configure database connections and embeddings, connect data sources, or troubleshoot a local installation.

It removes the need to drive ktx's interactive setup manually and helps keep connection details and secrets out of source control.

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.

Any agent

npx skills add skillmds/skillmd --skill ktx

Clone the repo

git clone --depth 1 https://github.com/skillmds/skillmd

Made for: Claude Code.

Or install data-ml, the plugin that ships this one along with the rest of its 17 skills.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00081	$0.02336
Opus 5.5	$0.00032	$0.00934
Sonnet 5.5	$0.00016	$0.00467
Haiku 4.5	$0.00008	$0.00234

Security

Grade A, and why

ktx 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 1mo 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 — 215 lines — stays where its author put it; the contents beside it link to each section on GitHub.

ktx

Install and configure ktx, the open-source context layer for data agents. Use this skill when a user wants an agent to add ktx to a project, connect data sources, build initial context, install agent integration, or troubleshoot a local ktx setup.

Operating rules

Act autonomously when the user asks you to install or configure ktx. The non-interactive scripted flow below is the canonical path — bare ktx setup is interactive (clack prompts) and an agent cannot drive it.
Setup's non-interactive flags are intentionally hidden from --help. Use the flags listed below; verify uncommon flags against the docs at https://docs.kaelio.com/ktx/ or this skill — not against --help output.
Ask only for values you cannot infer: project directory, connection targets, credentials, account identifiers, and source selections.
Never ask the user to paste secrets when an env:VAR_NAME or file:/path reference would work. Pasting a literal URL is also safe — ktx setup auto-externalizes URLs into .ktx/secrets/<id>-url (see workflow step 2).
Do not commit .ktx/secrets/*.
Print each command you run and its result.
If a command fails, identify the cause and change something before retrying.

Gather inputs once

Before invoking ktx setup, collect in one round:

Project directory (default: current working directory).
LLM backend and key strategy. In --no-input mode the CLI defaults to anthropic and requires an API key. When the user is inside Claude Code, pass --llm-backend claude-code explicitly; otherwise pass --llm-backend anthropic --anthropic-api-key-env ANTHROPIC_API_KEY.
Embedding backend (sentence-transformers is the local default and needs no key; use openai only if the user already has a key, then pass --embedding-api-key-env OPENAI_API_KEY).
Database: driver, connection id, URL (or env: / file: ref), and one or more schemas.
Optional context sources (dbt, Metabase, Looker, LookML, MetricFlow, Notion). Add each one with a follow-up ktx setup --source … run (see Add context sources); use --skip-sources only when the user has none.

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.

ktx is a skill published in the GitHub repository skillmds/skillmd (143 stars, last pushed 4d ago), licensed MIT. It adds 81 tokens to every session and 2,336 once invoked, about $0.0003 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 2026-09-19.
