eval-import

eval-import is a skill for Claude Code, Codex from malloydata/publisher. It costs 142 tokens per session (5,563 once invoked), scanned A, original, MIT.

An evaluation-set importer that turns questions from files, spreadsheets, documents, emails, or production logs into structured JSONL test cases. JSONL is a text format with one JSON object per line.

In plain words
What is it for?
Use it to import question lists, map their accompanying data into evaluation cases, place the cases beside the model's repository, and record what each item is worth.
Why use it?
It standardises questions before an AI system is evaluated and keeps the test set separate from the package being tested, reducing the risk of contaminating results.

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

eval-import 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 24d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/import_cases_test.py, scripts/import_cases.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 — 422 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Import questions into an eval set

Questions arrive in whatever shape their author had. This turns them into evals/<set>/, ready for a run, and records what each key is actually worth.

Scope boundary: cases only. This never answers a question, scores an answer, or edits a model. It is skill:eval-loop's scrape step, expanded, and it is where the set's honesty is decided.

The file shapes are defined once, in reference/ledger-schema.md of skill:eval-answer. Read them there; this skill does not restate them. reference/case-format.md covers what is specific to an import: which fields an arriving item maps to, and the four physical formats.

Where the set goes

Two separate rules, and "package" blurs them:

  • The same git repository as the model it evaluates, so one commit pins the model and the ledger together. That is what a checkpoint is.
  • Never inside the directory tree the answerer's package serves. The answerer can read files in the served tree, and gold there is a contamination path.

So the set is a SIBLING of the package under test, in its repo. A repo with ecommerce/ under test gets evals/ecommerce-questions/, beside it.

Step 1: keep the file as it arrived

Copy it verbatim into evals/<set>/as-received/, and never edit that copy. Not the encoding, not the line endings, not an obvious typo.

It is there so a later disagreement is about the key and not about whether somebody transcribed the question correctly. That disagreement is guaranteed: skill:eval-loop's reference/auditing-an-answer-key.md is about what happens when it arrives, and its first check is the question against this file.

If the source cannot be committed, because it carries names, addresses, internal URLs, or row values somebody pasted into a thread, say so. Record in set.json where the original lives and a hash of it, note under sourceNote that the copy is withheld and why, and tell the user that the byte-for-byte check is now impossible for anyone without the original. Do not redact silently: a redaction you got wrong becomes the provenance record.

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.
