- Updated July 10, 2026
- sancovp/sdna
twi-marketplace is a Claude Code plugin catalog that ships SDNA, a gnostic agent workflow DSL so developers can compose Ariadne context chains and Poimandres generation units on the Claude Agent SDK.
About
twi-marketplace is the TWI Community Claude Code catalog publishing the SDNA plugin for gnostic agent workflow composition on the Claude Agent SDK. SDNA combines Ariadne context threading with Poimandres generation into composable SDNAC units and SDNAFlow chains. Use it when you are building reusable multi-step agent pipelines with human checkpoints rather than one-off chat prompts.
- SDNA DSL: Ariadne threading + Poimandres generation spiral
- SDNAC single units and SDNAFlow sequential chains
- Context inject, weave, dovetail, and human pause steps
- TWI marketplace plugin with chain-development skills

How do I compose multi-step Claude Agent SDK workflows with context threading, human gates, and sequential agent units?
Composes gnostic agent workflows with SDNA's Ariadne threading and Poimandres generation for Claude Agent SDK chains.
Who is it for?
Developers building programmatic agent chains with sdna-agent-sdk who need SDNAC units, flows, or flowchain optimization loops.
Skip if: Teams wanting a no-code chat plugin only, or projects not using the Claude Agent SDK and Python sdna package.
What you get
Executable agent workflow units with threaded context, human approval pauses, and chained Poimandres generation outputs.

FAQ
What is the SDNA trinity?
Ariadne handles context threading, Poimandres runs generation, and HermesConfig carries runner configuration between them.
How is SDNA installed as a library?
pip install sdna-agent-sdk provides the Python DSL; the Claude plugin adds skills for chain development from the Twi Marketplace catalog.
When should I use SDNAFlow vs SDNAC?
Use SDNAC for a single threaded unit and SDNAFlow when composing multiple SDNAC units in sequence; SDNAFlowchain adds optimization loops.
