Claude Code

A status line for Claude Code: a powerline drawn on the same six-step ramp as the Starship prompt, so the prompt above the input box and the status line below it read as one instrument.

Left to right, the line carries the session badge (vim mode, agent name, and session name, when any of them is set), the directory, and the git branch with its dirty flags, upstream distance, the lines added and removed this session, and the open pull request as a clickable link coloured by its review state. A linked worktree gets its own glyph. The node version and Kubernetes context follow. On the right sit the model with its fast mode and effort level, context usage as tokens and a percentage, the session cost, the five-hour and seven-day rate limit windows, the output style, and the clock.

A reading that reaches 80 percent (context or a rate limit window) turns into a warning pill, and at 90 a danger pill, in the variant's own warning and danger colours. A snowflake after the context reading means the prompt cache has gone cold and the next request re-reads the whole prefix.

When the terminal is narrower than the line, readings drop in order: the tech probes, then output style, cost, and rate limits, then the git details, the session badge, and last the clock. The model and the context reading never drop.

Install

Claude Code reads one script, so pick a variant and copy it:

cp extras/claude/silkcircuit-neon.sh ~/.claude/statusline.sh

Then point Claude Code at it in ~/.claude/settings.json and restart:

{
  "statusLine": {
    "type": "command",
    "command": "~/.claude/statusline.sh",
    "refreshInterval": 30
  }
}

refreshInterval is optional. Without it the line redraws on every message, which is enough for everything except the clock.

The installer does the copy and prints that block: ./install.sh --variant neon. It leaves settings.json alone, because Claude Code owns that file and rewrites it as hooks, plugins, and permissions change.

Needs a Nerd Font

The powerline separators and the segment glyphs come from a Nerd Font, so the terminal running Claude Code has to use one.

Fast by design

The script needs no jq. The payload is read with bash regex matches, which keeps it linear on the two kilobytes Claude Code sends; a prefix strip would be quadratic on the bash 3.2 macOS ships. One git status call per render carries the branch, upstream distance, and every flag, and the node and kubectl probes are cached for a minute per directory. A render lands in about twenty milliseconds on a stock Mac, most of it git.
