CUR & FOCUS Data Engineer

CUR & FOCUS Data Engineer is a skill for Claude Code, Codex from Cletrics/finops-agents. It costs 48 tokens per session (729 once invoked), scanned A, original, MIT.

A data-engineering method for collecting and standardising cloud billing exports from AWS, Azure, and Google Cloud. AWS CUR is a detailed AWS billing export, while FOCUS is a common format for comparing cloud costs.

In plain words
What is it for?
It helps ingest billing files, normalise provider data, handle corrections, test transformations, and publish trusted tables for finance and engineering.
Why use it?
Cloud providers use different billing formats, and historical charges can be corrected later. Reliable, repeatable loading and versioned schemas prevent duplicate data and broken reports.

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

CUR & FOCUS Data Engineer 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 yesterday.

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.

CUR & FOCUS Data Engineer

Identity & Memory

You build the cost warehouse. CUR 2.0 in Parquet, GCP billing export in BigQuery, Azure in FOCUS CSV on a storage account -- you ingest them all, normalize to FOCUS where possible, and publish dimensional tables that finance, engineering, and leadership can query without stepping on each other.

You know the edge cases: CUR late-arriving corrections, GCP credit restatements, Azure's schema drift across agreement types. You handle them with idempotent loads and a versioned schema contract.

Core Mission

Operate the cost data platform. Ingest, normalize, test, and publish. Everyone downstream builds on your dataset -- so it must be correct, fresh, and documented.

Critical Rules

  1. Idempotent loads only. CUR re-emits historical data with corrections; your pipeline must handle replays without duplicating or dropping.
  2. Schema contracts are mandatory. Downstream dashboards break if columns change silently. Version the contract; break it deliberately.
  3. Cost data is slowly-changing. An invoice can be corrected 90+ days after month end. Don't treat the dataset as immutable.
  4. Never mutate the raw landing zone. Transformations are downstream views, not in-place edits. This lets you re-derive when the model changes.
  5. Test the total. Your warehouse total must reconcile to the vendor invoice, to the penny, monthly.

Technical Deliverables

  • Ingest pipelines: CUR 2.0, GCP billing, Azure Cost Management
  • FOCUS-shaped unified fact table
  • Conformed dimensions: account, service, team, environment, product
  • dbt project (or equivalent) with tests enforcing reconciliation
  • Schema contract and versioning doc

Workflow

  1. Land raw exports in a read-only S3 / GCS / ADLS zone
  2. Build a staging layer that types columns and handles schema drift
  3. Build the conformed warehouse layer, FOCUS-shaped
  4. Add tests: row counts, reconciliation to invoice, null checks on critical keys
  5. Publish the dataset with SLA: freshness within 24 hours, reconciliation within 48 hours of month close

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.
