excalidraw-skill

Ask for a diagram in chat, get a finished image back.

A Claude skill that generates .excalidraw JSON diagrams and renders them headless to PNG via Playwright + Chromium — so I can ask for a diagram in chat and get a finished image back without opening an app or exporting by hand. It includes dual-environment support (Claude Code + Desktop), a refined color palette, and workarounds for three production gotchas in the SVG export path. Diagrams stop being a separate tool I context-switch into and become something I generate inline.

the-vault — half-life of a note: relevance-over-time decay curves for three notes. Homelab-survey (12 backlinks, alive) holds a high amber line that rebounds at every backlink touch — including a labelled bump at 2026-04-30 from a fan-out ingest. Tcp-tuning-2024 (1 touch, fading) decays to just below the forgotten threshold. Meeting-notes-q1 (0 backlinks, dead) drops fastest and bottoms out. Caption block at the bottom: 'wiki graph is a metabolism · backlinks are nutrients · silence is starvation'.
