operator-extend

operator-extend is a skill for Claude Code, Codex from khaosans/operator-etl. It costs 33 tokens per session (229 once invoked), scanned A, original, Apache-2.0.

A guide for adding new data sources, subject areas, and reporting tables to Operator ETL. It explains how to configure sources such as CSV files, web addresses, and Google Cloud Storage.

In plain words
What is it for?
Use it to add an input source, create a new data domain, define its data rules, add reporting SQL, update the pipeline configuration, and verify the changes.
Why use it?
It turns a broad extension task into specific repository changes and tests. It also helps keep data contracts, SQL reports, and allowed quality checks aligned.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is ./harness/e2e.sh.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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

operator-extend 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 1mo 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.

What it actually says

Extend Operator ETL

Load: extend-new-source.md and repo-map.md

Add a source

  1. Edit pipelines/*.yaml — new entry under sources:
  2. Supported kinds: csv, csv_dir, http, gcs
  3. Add test in tests/

Add a domain

  1. Pydantic contracts in src/operator_etl/transform/
  2. Gold SQL in sql/marts/<domain>/
  3. Update Settings.domain and pipeline YAML domain: gov

MCP allowlist

New quality queries → add to sql/allowlist.yaml with allowed_nodes.

Verify

uv run pytest -q
./harness/e2e.sh
Changes

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.
