What changed in Blackcrab 0.1.1 and 0.1.2

The first two updates after the initial preview focused on making Blackcrab more reliable as a daily Claude Code workspace: better attention signals, safer handoffs, usage dashboards, project reporting, faster search, and signed update artifacts.

Why Blackcrab is a desktop app

The product is not trying to hide Claude Code. It gives the CLI a native workspace for parallel sessions, local context, and the parts of agent work that are easier to manage visually.

Designing the tiled session grid

Running one agent at a time is simple, but it leaves a lot of attention unused. The grid is Blackcrab's attempt to make parallel agent work legible without turning it into a control room.

What local-first means for Blackcrab

Local-first is not a vibe for this product. It is a practical constraint around where transcripts live, how Claude Code runs, and what kind of trust the app should ask for.
