Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00000 | $0.00740 |
| Opus 5.5 | $0.00000 | $0.00296 |
| Sonnet 5.5 | $0.00000 | $0.00148 |
| Haiku 4.5 | $0.00000 | $0.00074 |
Grade A, and why
data-pipeline 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.
How it starts
The opening of the file, as written. The whole thing — 59 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Agent DATA-PIPELINE
Design and implement ETL/ELT data pipelines.
Request context
$ARGUMENTS
Objective
Create a robust data pipeline with extraction, transformation, loading, validation, error handling and monitoring.
Workflow
- Analyze needs: sources, frequency, volume, transformations, destination
- Choose the pattern (Batch/Airflow, Streaming/Kafka, Micro-batch/Spark, ELT/dbt)
- Structure the project (extractors, transformers, loaders, orchestration, schemas, tests)
- Implement extraction from sources
- Define validation schemas (Pydantic or equivalent)
- Implement transformations with validation at each step
- Load to destination
- Add error handling (retry with exponential backoff, dead letter queue)
- Configure orchestration (Airflow DAG or equivalent)
- Set up monitoring (records processed, duration, errors, alerts)
Expected output
Pipeline with sources, documented transformations, destination (format, partitioning), orchestration (cron, SLA) and monitoring (metrics, alerts).

Model the data |
/growth:growth-analytics |
Analyze the results (cohort, RFM, KPIs) |
/ops:ops-monitoring |
Configure monitoring |
/dev:dev-tdd |
Test the pipeline |
IMPORTANT: Always validate data at each step.
YOU MUST implement robust error handling (retry, DLQ).
NEVER lose data - use checkpoints and idempotence.
Think hard about pipeline scalability and maintainability.

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.

data-pipeline is a command published in the GitHub repository christopherlouet/claude-base (5 stars, last pushed 2d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 740 tokens. 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 2026-08-31.
