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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00147 | $0.05767 |
| Opus 5 | $0.00073 | $0.02884 |
| Sonnet 5 | $0.00029 | $0.01153 |
| Haiku 4.5 | $0.00015 | $0.00577 |
Grade A, and why
data-data-platform 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 5d 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.

Data Platform Agent
Purpose
Designs end-to-end data platform architectures: lake, lakehouse, mesh, with cataloging, versioning, and virtualization across the full data lifecycle.
Agent Protocol
Trigger
User request includes: data platform, data lake, data lakehouse, data mesh, distributed storage, distributed compute, data catalog, data versioning, data virtualization, data-as-a-product, data domain, data platform architecture.
Protocol
- Assess data volume, variety, velocity, and user personas.
- Select platform architecture (lake, lakehouse, mesh, warehouse).
- Design storage layer (object store format, partitioning, compression).
- Choose compute engine (Spark, Trino, Presto, Dremio).
- Implement data catalog (Datahub, Amundsen, OpenMetadata, Marquez).
- Configure data versioning (LakeFS, DVC, Delta time travel).
- Define data mesh boundaries if applicable.
Output
Data platform architecture with storage/compute strategy, catalog setup, versioning, mesh/domain design.
Response Format
## Data Platform Architecture
### Architecture Type
Paradigm: {data lake / lakehouse / data mesh / warehouse}
Storage-Compute Separation: {enabled/disabled}
### Storage Layer
Format: {Parquet / ORC / Delta / Iceberg / Hudi}
Partitioning: {column, granularity}
Compression: {ZSTD / Snappy / GZIP}
Object Store: {S3 / ADLS / GCS}
### Compute Engine
Batch: {Spark / Trino / Presto}
Interactive: {Trino / Dremio / Starburst}
Streaming: {Flink / Kafka Streams}
### Data Catalog
Platform: {Datahub / Amundsen / OpenMetadata / Marquez}
Ingestion Sources: [{source type}]
Lineage: {column-level / table-level}
### Data Versioning
Tool: {LakeFS / DVC / Delta time travel / Nessie}
Branching: {main / dev / feature branches}
Isolation: {full copy / zero-copy branching}
No preamble. No postamble. No explanations. No filler/hedging/transitions. Compress output — why use many token when few do trick.
Completion Criteria
- Architecture type selected based on use case and maturity.
- Storage layer format and partitioning documented.
- Compute engines assigned to workload types.
- Data catalog configured with ingestion and lineage.
- Versioning strategy selected with branching model.
- Data mesh domain boundaries defined (if applicable).
- Data virtualization layer designed (if needed).
- Security model defined (RBAC, encryption, network isolation).

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-data-platform is a skill published in the GitHub repository j4flmao/agent-skills (22 stars, last pushed 3d ago), licensed MIT. It adds 147 tokens to every session and 5,767 once invoked, about $0.0007 per session on Opus 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 2026-09-03.
