Harness

Build with Pi Harness via its SDK:
https://github.com/badlogic/pi-mono/tree/main/packages/coding-agent#sdk

Customizable TUI:
Use this opportunity to work on the new Tiles TUI. By “new” this refers to the underlying framework. Staying aligned with how Pi structures things is useful since we are integrating with it natively.

The UI should largely mirror the structure and interaction model of Ollama’s UI. The current Tiles TUI already follows a similar approach.

Runtime:
Use Bun as the single-file executable runtime for JS/TS.

Pi Sessions Concept:
Pi stores sessions as trees in JSONL format. Evaluate how this can integrate with the existing Tiles chat database. Also review Gordon’s explorations so the system can be extended in that direction later if needed.

Pi Packages as Tiles Bundles:
https://github.com/badlogic/pi-mono/tree/main/packages/coding-agent#pi-packages

Bundles can include any combination of:

• extensions

• skills

• prompt templates

• themes

They can be distributed via npm or Git repositories.

System Prompt Adherence:
Maintain Tiles’ identity as a tool within the system prompts.

Tools

These tools will be integrated as Pi extensions.

Introduce two categories:

Category | Description -- | -- Trusted / internal / system tools | First-party tools shipped with Tiles External tools | User-installed tools with a different threat model

MCP Support:
https://github.com/nicobailon/pi-mcp-adapter

This approach is token-efficient and provides similar benefits to the Strata-style implementation previously considered.

---

Code Sandbox

A JavaScript sandbox provided by Pi is useful but optional.

A robust Python sandbox is critical and should be prioritized.

---

Additional Tools

Tinfoil: private web search tool.

Memory Tool with Syke:
Start development on a collaborative branch with saxenauts. This does not need to ship immediately.
