# Herdr Dispatch Budget -> split -> start -> brief -> collect -> verify -> clean up. The `Herdr` instruction decides *that* subagents become panes. This decides *how*. Policy lives there; do not restate it here. ## Preconditions ```bash test "${HERDR_ENV:-}" = 1 # else: not inside Herdr, stop printf '%s\n' "$HERDR_WORKSPACE_ID" "$HERDR_TAB_ID" "$HERDR_PANE_ID" ``` Not inside Herdr -> say so and fall back to the `Agent` tool. Never control a Herdr session from outside it. ## Pane Budget Claude Code's TUI is unusable below ~60 columns; budget at 68 so a worker can render a diff rather than merely survive. Splitting a tab N ways divides its width by N. Workers belong in their own tab - the user's driving pane stays uncluttered and their focus stays where they put it. Create that tab **first**, then measure it: ```bash herdr tab create --workspace "$HERDR_WORKSPACE_ID" --label "workers" --cwd "$PWD" --no-focus # -> .result.tab, .result.root_pane herdr pane layout --pane "<root-pane-id>" # -> .result.layout.area.width ``` **`--workspace` is not optional.** Omit it and the tab is created in whatever workspace currently has focus, which is routinely not yours - the user clicks into another project and every worker tab lands there. `--cwd` still points the agents at the right directory, so the work itself comes out correct and the mistake shows up only as panes scattered in someone else's space.
