Agent Workflows

Level 7 — Recursive prompt optimization for AI agents.

The Story​

You're building an AI agent (in LangChain, n8n, or custom code). The agent's behavior depends on its system prompt. You need to iterate, test, and improve the prompt systematically.

The Problem​

Without semantic version control:

  • Prompts are scattered in code files
  • "Which version worked better?" — nobody knows
  • Agent logs are disconnected from prompt changes
  • Manual copy-paste to test variations

The Solution​

T3x treats prompts as semantic artifacts with full version control.

Workflow​

1. Commit your initial prompt​

T3x> /new travel-agent
T3x> System prompt: You are a helpful travel booking assistant...
T3x> /commit --api --msg "travel-agent-v1"

2. Create sandbox branch​

T3x> /branch sandbox

3. Run agent, capture logs​

# Your agent runs, logs come back
T3x> Agent run: User asked about Tokyo. Response was helpful.
     Success rate: 85%
T3x> Agent run: User asked about refunds. Agent confused.
     Error: Didn't know refund policy.

4. Draft improvements​

T3x> /draft --api plan "Improve the prompt based on failure cases"

T3x analyzes logs and suggests:

  • Add refund policy to system prompt
  • Clarify edge case handling

5. Auto-iterate on sandbox​

# Commit improvement
T3x> /commit --api --msg "Added refund policy handling"

# Run again, capture new logs
# Repeat...

6. Promote to production​

When sandbox is stable:

T3x> /checkout prod
T3x> /diff prod sandbox  # Review changes
T3x> /merge sandbox      # Requires human approval

The Recursive Loop​

Prompt → Agent Run → Logs → Draft → Commit → Repeat
   ↑                                          │
   └──────────────────────────────────────────┘

Key Benefits​

  • Every prompt version is traceable — git blame for prompts
  • Logs inform improvements — Failures become draft input
  • Safe iteration — Sandbox experiments don't affect prod
  • Clear promotion path — Review before production
  • Semantic diff — See what changed at the clause level

Integration​

Works with:

  • LangChain
  • n8n
  • Flowise
  • AutoGPT
  • CrewAI
  • Custom agents

The agent framework runs the prompt; T3x versions and improves it.
