foundations

foundations is a skill for Claude Code from openshift-eng/ai-helpers. It costs 30 tokens per session (1,132 once invoked), scanned A, original, Apache-2.0.

Shared safety instructions for running BigQuery queries against OpenShift CI data. They require showing queries, checking how much data they will scan, controlling costs, and using cached results where appropriate.

In plain words
What is it for?
Use them whenever querying the supported CI datasets, especially to preview queries, estimate costs, set the project explicitly, and request confirmation for expensive work.
Why use it?
They reduce accidental expensive queries and make the data access process easier to review before a query runs.

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

foundations 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 16d 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.

BigQuery CI Data Foundations

Shared foundations for all CI data BigQuery skills. Every skill in this plugin follows these protocols.

Prerequisites

  • bq CLI installed and authenticated (gcloud auth login)
  • BigQuery read access to the relevant projects

Projects and Datasets

Project Dataset Purpose
openshift-gce-devel ci_analysis_us Primary engineering CI data (jobs, junit, variants, labels)
openshift-gce-devel ci_analysis_qe QE CI data (same schema as ci_analysis_us, smaller)
openshift-ci-data-analysis ci_data_autodl Auto-collected data from test runs (disruption, CPU, audit logs, risk analysis, etc.)

Always pass --project_id=<project> explicitly to all bq commands.

Cost Safety Protocol

Non-negotiable. Every query follows this flow:

  1. Show the query to the user before doing anything
  2. Dry-run to get bytes scanned:
    bq query --project_id=<project> --dry_run --use_legacy_sql=false '<query>'
    
  3. Calculate cost: bytes / 10^12 * $6.25 (on-demand pricing)
  4. If cost > $1.00: show estimated cost and bytes, ask user to confirm
  5. If cost <= $1.00: proceed, report cost in results
  6. Never loop or repeat queries. Run once, cache locally, analyze from cached data.

Partition and Clustering Filters

When a table is partitioned, every query MUST include a filter on the partition column to avoid full-table scans. Use tight date ranges. Not all tables are partitioned (e.g. job_variants is small and unpartitioned).

When a table is clustered, filter on the clustering column too for major cost reduction.

Caching Results Locally

After executing a query, save results to .work/bigquery-ci-data/ as JSON or CSV. Name files descriptively.

Always query fresh — never skip a query because a cached file with a similar name already exists. CI data changes continuously; stale cache files produce misleading results. Use cached files only for follow-up analysis of the same data within the same conversation, and re-query if more than 4 hours have passed since the cache was written.

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.

foundations is a skill published in the GitHub repository openshift-eng/ai-helpers (121 stars, last pushed today), licensed Apache-2.0. It adds 30 tokens to every session and 1,132 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-10-06.
