Internal SmartGift build of a Claude Code monitoring dashboard. Lanes: a durable unit of parallel agent work, one per working directory, tracked across session restarts. Managed lanes are git worktrees the dashboard provisions and can reset or remove behind a three-check destroy guard and a counted preflight; adopted lanes are directories you already own and are never destroyable. Pipelines: a lane moves through pipeline stages. A stage the agent declares with evidence renders green; a stage inferred from the tool-event stream renders dashed amber and never counts as done. Detection is forward-only within a 30-minute window, and never writes the declared stage. Workspace: one page at /run with a lane grid, the selected lane's pipeline, and a full Claude console behind a disclosure.

statusline.py — Claude Code custom statusline renderer.
|
|
|
|
Reads a JSON event payload from stdin (emitted by Claude Code on every turn)
|
|
and prints a single ANSI-colored status line to stdout. Renders the model
|
|
display name, current user, working directory (with home collapsed to ``~``),
|
|
active git branch, a color-coded context window usage bar (green / yellow /
|
|
red thresholds), and token counts. Always exits 0 so it can never block
|
|
Claude Code — missing fields are silently skipped.
|
|
|
|
Intended to be referenced from Claude Code's ``statusLine`` setting (see
|
|
``statusline-command.sh`` for the wrapper) or installed to
|
|
``~/.claude/statusline.py``.
