The instructions your model reads when the skill loads.

SKILL.md266 linessingle file

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.
Prefer file:/abs/path secret refs over env:VAR_NAME. env: refs are re-resolved against the process environment on every ktx run, so a var exported only in the setup shell is gone when ktx ingest or ktx mcp start runs later — the secret silently resolves to empty and the connection fails. file: refs read from disk and survive across shells. The same caveat applies to --*-api-key-env flags: the named var must be present in every shell that runs ktx, including the ktx mcp daemon's environment.
A literal database URL is safe to pass — ktx setup auto-externalizes it into .ktx/secrets/<id>-url and rewrites ktx.yaml to a file: ref (see workflow step 2). Source credential refs are not auto-externalized: write the secret to a file under .ktx/secrets/ (chmod 600) and pass a file: ref. Never ask the user to paste a secret when a file: or env: ref works.
Do not commit .ktx/secrets/*.
Print each command you run and its result.
Setup and ingest can run for many minutes (LLM-heavy source ingests take the longest), and from the outside a slow step looks identical to a stuck one. Don't go silent: say what's about to run and that it may take a while, then post brief progress/liveness updates while it runs (see step 4) so the user never has to wonder whether it stalled — otherwise they may kill it mid-run.
If a command fails, identify the cause and change something before retrying.
