kitaru-importer-builder

kitaru-importer-builder is a skill for Claude Code from zenml-io/kitaru-skills. It costs 102 tokens per session (3,006 once invoked), scanned A, a copy of kitaru-importer-builder, Apache-2.0.

A guide for building a custom importer that converts trace exports into Kitaru sessions and nodes. Trace exports are records of what an AI agent or software system did during a run, while Kitaru is the target system for organizing those records.

In plain words
What is it for?
Use it to inspect a representative export, map its structure, and create a locally tested importer. It also covers joining individual turns into sessions and handling incomplete or failed traces.
Why use it?
It helps when a provider, monitoring platform, export format, or agent framework has no suitable built-in importer. It makes clear which information is preserved, approximated, or unavailable.

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

kitaru-importer-builder scanned grade A with 1 finding 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 today.

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.

How it starts

The opening of the file, as written. The whole thing — 194 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Kitaru importer builder

Turn representative provider data into a locally validated Kitaru importer for static exports or bounded API queries. Keep the path from source evidence to normalized sessions explicit so the user can see what is preserved, approximated, or unavailable.

Finish locally by default. Register code or upload trace data only when the user asks and approves each action separately.

Core contract

  • Treat the installed Kitaru version and its offline schema as authoritative. Use repository examples as patterns, not proof that a command or field is installed.
  • Treat trace content as sensitive. Keep raw exports out of version control and redact fixtures before writing them into the target repository.
  • Keep parsing separate from acquisition. The parser consumes bytes and parameters without network calls, filesystem writes, subprocesses, or credential reads; an optional fetch(query) method may read provider credentials and request API payloads.
  • Map the source before writing code. Record accepted payload shapes, identity, hierarchy, ordering, node fields, status, completeness, and intentionally unsupported data.
  • Prefer a private, single-file script importer. Use a package only when the user already has a distribution reason and the worker can install one exact pinned version.
  • Preserve useful incomplete evidence. Distinguish an unreadable payload, an invalid item, and a valid but incomplete session.
  • Join traces conservatively. A common key is insufficient without source-instance scope and meaningful turn order.
  • Do not overwrite an existing importer file, register executable code, upload trace data, or retry a partial import without an explicit checkpoint.
  • Ask separately before installing the exact importer dependencies and before running a local importer test.
  • Run local tests of any untrusted or newly generated importer, including code created in the current task, only in a credential-free isolated environment. Stop if that isolation is unavailable.
  • Treat local importer testing as code execution in a bounded child process, not as a security sandbox.
  • Offer packaging or upstream contribution only after local success. Do not make either a completion requirement.
  • Run every Kitaru CLI command and SDK script with KITARU_ACTIVE_SKILL=kitaru-importer-builder set so the server attributes the resulting activity to this skill.
  • Start or restart a user-controlled worker with --concurrency 10. Use KITARU_WORKER_CONCURRENCY=10 only when the launch surface exposes worker settings through environment variables instead of CLI options.

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.
