README

shellcast

Live inline cards for every shell command Claude runs, right in the Claude Code transcript. No side panel.

I got tired of my agent's shells being reduced to this:

Claude Code's footer: auto mode on · 1 shell, 2 monitors · 1 agent

What is that shell doing? Is it stuck? How far along is it? shellcast puts every shell command Claude runs right in the transcript as a live card, and keeps long background jobs in sight while the agent goes on writing. Quick commands stay as one-line rows with their own icons. Completed tool blocks collapse into a summary of the work and an icon strip, keeping the whole sequence easy to scan:

Stock Claude Code (left) · shellcast (right)
Synchronized before and after: stock Claude Code on the left; shellcast on the right with descriptive tool summaries, command icons, compact writes, and a live build card

The same prompt, tool calls, file contents, and eight-second build, with synchronized scripted replies. A search, a file read, and nine shell commands collapse into descriptive blocks with their icons intact; three Write summaries stay compact. Icons use SHELLCAST_ICONS=nerd-bold.

Open the full-size comparison, individual before / after videos, or the short icons + writes demo.

While a command is running you can see its output, progress and throughput. Once it finishes, the card folds into a single line:
