data-architecture-design

data-architecture-design is a skill for Claude Code, Codex from Future-CX/AI-Architecture-Toolkit. It costs 62 tokens per session (2,868 once invoked), scanned A, original, MIT.

A guide for documenting how a specific business data object is defined, owned, stored, moved, protected, and governed. A canonical data object is the agreed version of something such as a customer, order, or product record.

In plain words
What is it for?
It helps create data architecture documents with flows, system responsibilities, lifecycle rules, quality expectations, privacy and retention details, governance, assumptions, and open questions.
Why use it?
It exposes unclear ownership, conflicting definitions, missing quality rules, privacy concerns, and unknown integration details before they cause design problems.

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

data-architecture-design 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 3d 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.

The opening of the file, as written. The whole thing — 151 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Data Architecture Design

Quick Start

Assume the Data Architect Agent role from agents/data-architect.md: clarify the canonical data object, ownership, source of truth, lifecycle, quality, privacy, retention, integration flows, and governance expectations.

Before creating or updating any data architecture design files, run a grill-me clarification session using ../grill-me/SKILL.md. Ask one question at a time until the target architecture link, data object meaning, ownership, lifecycle, integrations, quality expectations, privacy concerns, assumptions, and open questions are clear enough to avoid avoidable misunderstanding.

During that clarification session, use ../ubiquitous-language/SKILL.md whenever terms are vague, missing, overloaded, conflicting, or important enough to become shared domain language. Create or update <private-lab-root>/GLOSSARY.md inline as terms are clarified; do not batch glossary updates until the end.

Use templates/data-architecture-design-template.md as the output structure. Replace placeholders and drafting guidance with concrete content; mark unknown facts as TBD or open questions.

Store generated data architecture designs under the consuming repository's private lab root:

data-architectures/<data-object-slug>/<data-architecture-basename>.md
data-architectures/<data-object-slug>/diagrams/

Derive <data-architecture-basename> without repeating data:

  • When <data-object-slug> ends in -data, use <data-object-slug>-architecture-design.
  • Otherwise, use <data-object-slug>-data-architecture-design.
  • Never generate a filename containing -data-data-.

Examples: customer-data becomes customer-data-architecture-design.md, customer-user-data becomes customer-user-data-architecture-design.md, and audiences becomes audiences-data-architecture-design.md.

Do not write real-company data architecture details into this public toolkit repository.

Required Inputs

  • Target architecture document to link to
  • Canonical data object name
  • Data object description and business purpose
  • Main capability or business process using the data object
  • Source of truth and data owner
  • Data classification
  • Producing systems, consuming systems, and integration touchpoints
  • Data lifecycle states, retention, privacy, and classification expectations
  • Known quality rules, reconciliation needs, lineage needs, and governance constraints

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-architecture-design is a skill published in the GitHub repository Future-CX/AI-Architecture-Toolkit (5 stars, last pushed 4d ago), licensed MIT. It adds 62 tokens to every session and 2,868 once invoked, about $0.0003 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 2026-08-31.
