+# Caps Escape Design
+
+## Facts
+
+- Commit `250b0b71f` removed `services.xserver.xkb.options` from the shared host module.
+- The removed option was `caps:escape_shifted_capslock`.
+- That XKB option maps Caps Lock to Escape.
+- Shift+Caps Lock still enables Caps Lock.
+- The shared host module configures Neogaia, Zeus, and Pikachu.
+- Zeus has QMK firmware that provides equivalent keyboard behavior.
+- Neogaia and Zeus enable `modules.host.cachyos` and `modules.desktop`.
+- Pikachu enables neither module.
+- `configs/nixos/hosts/neogaia/default.nix` directly sets Neogaia-specific hardware, networking, desktop application, and Waybar settings.
+- The current configuration has no Caps Lock or Escape remapping.
+- This session runs on Zeus, not Neogaia.
+
+## Design Tree
+
+- Restore Caps Lock behavior
+  - Scope the configuration
+    - Configure Neogaia only. ✓
+  - Select the mapping behavior.
+    - Restore `caps:escape_shifted_capslock`. ✓
+    - Set `services.xserver.xkb.options` in `configs/nixos/hosts/neogaia/default.nix`. ✓
+  - Define validation for Neogaia.
+    - Run static checks and manually verify both keys after deployment. ✓
+    - Stop after source and static validation. ✓
+
+## Settled Decisions
+
+1. Configure the mapping on Neogaia only.
+2. Restore `caps:escape_shifted_capslock`.
+3. Set `services.xserver.xkb.options` directly in Neogaia's host configuration.
+4. Run static checks and manually verify both keys on Neogaia after deployment.
+5. Stop after source and static validation.
+
+## Frontier
+
+None.

+# 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.
