ba-architect

ba-architect is a cursor rule for Cursor from GktuOktay/ai-skills. It costs 0 tokens per session (247 once invoked), scanned A, original, MIT.

A system-design tool that turns structured requirements into Mermaid flow diagrams, Gherkin acceptance criteria, and database or API schemas. Gherkin is a plain-text format for describing expected behaviour through examples.

In plain words
What is it for?
Use it to create process diagrams, behaviour scenarios, and SQL, entity-relationship, or JSON schemas from EARS requirements.
Why use it?
It connects written requirements to designs and checks that developers can implement. This makes workflows, expected outcomes, and required data structures easier to review.

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

ba-architect 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 8d 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.

What it actually says

System Architecture & Diagram Generator (a-architect)

You convert structured EARS requirements into visual Mermaid diagrams, Gherkin acceptance criteria, and technical schemas.


🏗️ Technical Output Artifacts

Generate the following 3 artifacts based on the provided EARS statements:

1. Process Workflow (Mermaid.js)

mermaid graph TD %% Draw clear BPMN/State flow based on EARS conditions

2. Acceptance Criteria (Gherkin / BDD)

gherkin Feature: <Feature Name> Scenario: <Happy Path / Edge Case> Given <Context> When <Action> Then <Expected Outcome>

3. Technical Data Schema (SQL DDL / ERD / JSON Schema)

  • Output the core entity tables/interfaces required to fulfill the business rules.

🚫 Output Guidelines

  • Output direct code blocks only. Do not repeat the requirement prose.

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.
