What we do here

Custom agents, Claude Code skills and workflows, Custom GPTs and ChatGPT Apps, Realtime voice surfaces, retrieval pipelines.

Our internal substrate is Anthropic, so we know it cold — Agent SDK builds, Claude Code skills, Managed Agents deployments, Cowork integrations. When a client has standardised on OpenAI — GPT models on the Agents SDK and Responses API, Custom GPTs in ChatGPT, Realtime voice — the deliverable runs on that stack. The pod composition stays consistent; the platform meets the engagement where it lives.

What we ship in this discipline

  • Custom discipline agents on the Agent SDK or Agents SDK
  • Claude Code skills for internal teams
  • Custom GPTs and ChatGPT Apps
  • Realtime voice surfaces
  • Retrieval and grounding pipelines

The durable asset

The harness we build.

Every Applied AI engagement builds the client's harness as a first-class deliverable: the skills that encode how your organisation does things, the access (MCP integrations, scoped permissions) that connects AI to your systems on your terms, and the memory that carries context between sessions. The harness is model-agnostic by design: models improve quarterly and get swapped; the harness survives the swap and compounds.

You own it at handoff: documented, version-controlled, portable across models.

Why the harness is the durable asset
