kitaru: Skill for Claude Code

.agents/skills/kitaru-importer-development/SKILL.md

kitaru-importer-development is a skill for Claude Code, Codex from zenml-io/kitaru. It costs 48 tokens per session (1,630 once invoked), scanned A, original, Apache-2.0.

A guide to building separately packaged Kitaru importers that turn exports from external providers into imported sessions.

In plain words
What is it for?
Use it to parse provider exports, define session boundaries, produce stable external IDs, register importer metadata, and populate supported session details.
Why use it?
It clarifies when a reusable importer package is appropriate and how to preserve source data, identify duplicates, and report bad records without stopping the whole import.

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-development 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 14d 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.

Kitaru Importer Development

Read AGENTS.md, plugins/AGENTS.md, plugins/DEVELOPMENT.md, and src/kitaru/task/importer.py. Treat the task module as the executable importer contract. Read the JSONL importer first for the smallest example, then the closest provider importer and its fixtures. Load the same-name kitaru-dev repo skill for the current host for the general command and PR workflow. When an importer version or another release unit changes, also load the kitaru-release skill before opening or updating the PR. State whether each changed distribution will ship in the next applicable release or be deferred past it; attach its exact release-unit label when publication is deferred past that release.

First decide whether the request needs a reusable package. A one-off conversion to Kitaru JSONL or a self-contained registered script may be smaller. Registration stores source metadata; it does not upload or vendor a package.

Implement the parser contract

Implement parse(payload: bytes, params: dict[str, Any]) as an iterator of ImportedSession or ImportFailure.

  • Choose and document the source-to-session boundary.
  • Derive a stable source external_id and use a nonempty importer provider. Kitaru 0.24.0 and later deduplicates on (imported_from, external_id, agent_id), across all versions of the destination logical agent. Kitaru 0.23.0 used a global provider/external-ID key; verify the destination server's contract when supporting older or unknown versions.
  • Preserve source inputs and outputs. Populate selectors, models, tokens, costs, reasoning selectors, framework, attributes, and metadata only when the export supports them without guessing.
  • Yield ImportFailure for an isolated bad record. An exception raised while starting or advancing the parser ends the import task.
  • Preserve valid node ordering and graph relationships. Use either nested nodes or the flat indexed form accepted by flatten_nodes; follow that function's validation rules.
  • Validate provider parameters and keep normalization or grouping provenance in metadata when it changes how the source is interpreted.

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.
