kitaru-importer-builder

kitaru-importer-builder is a skill for Claude Code, Codex from decodingai-magazine/building-a-coding-agent-from-scratch-course. It costs 96 tokens per session (2,781 once invoked), scanned A, original, Apache-2.0.

A guide for converting exported traces from a provider, monitoring system, file format, or agent framework into Kitaru sessions and steps. It validates the conversion locally while showing which source details are preserved or unavailable.

In plain words
What is it for?
Use it to map trace identities, ordering, hierarchy, statuses, and incomplete runs into Kitaru's format, then test the importer on a representative export.
Why use it?
It gives a structured way to use trace data when no built-in importer exists and reduces hidden data loss during conversion. It also keeps sensitive raw exports out of source control and avoids network access during parsing.

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 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 2d 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.

The opening of the file, as written. The whole thing — 182 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Kitaru importer builder

Turn a representative provider export into a locally validated Kitaru importer. 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 export acquisition outside the importer. The parser consumes static bytes and parameters without network calls, filesystem writes, subprocesses, or credential reads.
  • 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 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.

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.
