# Vibe Coding in Oracle MicroTx Workflows with a Codex/Claude Skill
# Summary
**Oracle MicroTx Workflows** is an enterprise-grade durable workflow orchestration platform built on the proven **Conductor** architecture. It combines durable execution, visual workflow design, AI agent orchestration, and transaction-aware coordination to help organizations build reliable long-running business and AI workflows.
I created a specific **MicroTx Workflows skill** for both **Codex** and **Claude** to make workflow development as simple as possible for beginners. Draft your workflows in natural language by providing a specification, then refine them step by step while deploying and debugging. Continue your work visually in the standard web console.
It helps define, run, inspect, and manage Oracle MicroTx workflows, connectors, agent profiles, and human task approvals through REST APIs.
A small step toward making agent-assisted workflow orchestration more practical.

**NOTICE**: *The skill has been tested on a local laptop MicroTx installation and is intended for learning and testing only.*
## About MicroTx Workflows
🔔**Oracle MicroTx 26.1** is generally available, uniting durable workflow orchestration (built on the open-source Conductor project) for both agentic and non-agentic workflows, with distributed transaction coordination for microservices (XA, Saga, TCC) in a single platform: on-premises, OCI, and multicloud.
🎯 The result: developers can build resilient enterprise applications that span databases, microservices, AI agents, SaaS, events, and Blockchain/DLT networks — while preserving transactional consistency where it matters most.

## Video Demo
This is an example of using the skill in both tools: Codex and Claude.
## Conversation example
### MicroTx Workflows definition & testing
- Send the following prompt to Codex/Claude:
```text
# Create a MicroTx workflow.
# Use the LLM connector set called "oci_llm_profiles" for any GENAI_TASK.
# Run on the local CONDUCTOR_SERVER_URL=http://127.0.0.1/workflow-server/api
Perform the following tasks in order:
# 1. Connect to the local instance of Conductor.
# 2. Create a new workflow named "vibe_loan" with these steps:
- INPUT: a loan request in natural language.
- GENAI_TASK (extraction). Using LLM model google.gemini-2.5-pro, extract these fields:
name (string)
age (integer)
amount (number)
duration (number)
scope (string)
- VALIDATION: if any of name, age, amount, duration, scope is missing or null,
abort the workflow with:
{ approve: false, reason: "minimum info not provided", missing_fields: [] }
and stop.
- DECISION RULES (evaluate in this exact order; first match wins):
Rule 1: if age > 50 AND amount > 100000
-> { approve: false, reason: "age over 50 and amount over 100000 not allowed" }
Rule 2: else if scope == "home purchase" AND amount >= 50000
-> { approve: true, reason: "home purchase, amount >= 50000" }
Rule 3: else if scope != "home purchase" AND amount < 50000
-> { approve: true, reason: "non-home purchase, amount < 50000" }
Rule 4: else
-> { approve: false, reason: "" }
# 3. Deploy the workflow.
# 4. Test A — expect approve = true:
"I need to purchase a house. I need 60000 euro. I'm 45 years old and
I need a mortgage for 20 years. My name is Corrado De Bari. Thanks."
(home purchase, amount 60000 >= 50000, age 45 -> Rule 2 -> true)
Verify the workflow returns approve = true.
# 5. Test B — expect approve = false:
"I need to purchase a boat. I need 120000 euro. I'm 60 years old and
I need a mortgage for 20 years. My name is Corrado De Bari. Thanks."
(age 60 > 50 and amount 120000 > 100000 -> Rule 1 -> false)
Verify the workflow returns approve = false.

### Query resources/workflows
- Question: `In the local MicroTx instance, give me the list of defined LLM providers`
- Answer:
```
• Local MicroTx has 2 LLM profiles defined:
Profile Provider Region Models
━━━━━━━━━━━━━━━━━━ ━━━━━━━━━━ ━━━━━━━━━━━━━━━━ ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
llm-oci OCI eu-frankfurt-1 cohere.command-plus-latest, xai.grok-3, xai.grok-4,
meta.llama-3.1-405b-instruct, meta.llama-3.3-70b-
instruct, openai.gpt-4o, openai.gpt-4o-mini,
openai.gpt-4.1, openai.gpt-5
────────────────── ────────── ──────────────── ─────────────────────────────────────────────────────────
oci_llm_profiles OCI eu-frankfurt-1 google.gemini-2.5-pro
So the only provider type currently configured is OCI, with two separate LLM profiles.
```
- Question: `Which DBs are configured?`
- Answer:
```
There is one DB configured:
oracle-database
- Engine: ORACLE
- Username: microtx
- Capabilities: RELATIONAL, VECTOR, EMBEDDING_GENERATION
- URL: jdbc:oracle:thin:@tcps://adb.us-ashburn-1.oraclecloud.com:1522/xyz_tpurgent.adb.oraclecloud.com
- Max pool size: 15
Password and wallet are masked by MicroTx.
```
- Question: `Have any vibe_loan processes been executed? Give me the list and the related input/output for each process.`
- Answer:
```
Yes. There is one executed vibe_loan_claude process.
