# TL;DR command design

## Goal

Add a Pi command that summarizes the preceding agent response by default.
An explicit command argument identifies the source to summarize.

## Decision tree

- Command form and scope
  - Settled: Create a project prompt template at `.pi/prompts/tldr.md`.
  - Command interface
    - Settled: Pass arguments through as a free-form source request.
    - Default source selection
      - Settled: Summarize the preceding agent response when no source request exists.
      - Summary format and length
        - Settled: Use a compact, format-free summary.
        - Ambiguous-source behavior
          - Settled: Add no special handling policy.

## Settled decisions

- **Q1 — Command form and scope:** Create a project prompt template.
- **Q2 — Explicit source interface:** Accept a free-form source request.
- **Default source selection:** Summarize the preceding agent response when the command has no arguments.
- **Q3 — Summary shape:** Use a compact, format-free summary.
- **Q4 — Unavailable source:** 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.
The prompt adds no special policy for unavailable or unclear sources.
