# TL;DR command design tree

This tree reviews the implementation decisions in `tldr-design.md`.

## Settled decisions

- **Command form and scope:** Add the project prompt template `.pi/prompts/tldr.md`.
- **Explicit source interface:** Interpret command arguments as a free-form source request.
- **Default source:** Summarize the preceding agent response when no source request exists.
- **Summary shape:** Produce a compact summary without a fixed format.
- **Unavailable or unclear sources:** Add no special handling policy.

## Frontier

The frontier is empty.

## Shared understanding pending confirmation

The project gets a `/tldr` prompt command in `.pi/prompts/tldr.md`.
Without arguments, it summarizes the preceding agent response.
With arguments, it interprets them as a free-form source request.
It produces a compact summary with no fixed format or language policy.
The prompt adds no special policy for unavailable or unclear sources.
